Description

本発明は、静止画と動画を撮影可能な撮影装置及び撮影方法に関し、具体的には動画撮影中に静止画を撮影できるデジタルカメラに関する。   The present invention relates to a photographing apparatus and a photographing method capable of photographing a still image and a moving image, and more specifically to a digital camera capable of photographing a still image during moving image photographing.

図7は、従来のデジタルカメラの斜視図である。キャビネット(2)上には、シャッタ釦(20)、撮影レンズ(21)、ストロボランプ(27)、液晶パネルであるディスプレイ(22)、メモリカード(4)が挿入されるスロット(23)が、周知の如く配備される。   FIG. 7 is a perspective view of a conventional digital camera. On the cabinet (2), there are a shutter button (20), a photographing lens (21), a strobe lamp (27), a liquid crystal panel display (22), and a slot (23) into which a memory card (4) is inserted. It is deployed as is well known.

近年、フォトダイオードなどの光電変換素子を2次元に配列した固体撮像素子を利用したデジタルスチルカメラにおいて、動画と静止画の夫々を撮影できるものが普及している。このような撮影装置に用いられる固体撮像素子には、光電変換素子で撮影されて得られた電荷を電位障壁を用いて画素毎に転送するCCD(Charge Coupled Device)がある。   In recent years, digital still cameras using a solid-state imaging device in which photoelectric conversion elements such as photodiodes are two-dimensionally arranged are capable of shooting moving images and still images. A solid-state imaging device used in such an imaging apparatus includes a CCD (Charge Coupled Device) that transfers charges obtained by imaging with a photoelectric conversion element for each pixel using a potential barrier.

図9は、従来のデジタルカメラの内部ブロック図である。撮影レンズ(21)は駆動機構(
図示せず)により、光軸に沿って移動可能であり、被写体の像は撮影レンズ(21)により絞
り(54)を通ってCCD(5)上に結ばれる。CCD(5)は、ドライバ回路(56)にて制御され、受けた光信号を電気信号である画像信号に変換して出力し、該画像信号はCDS(相関二重サンプリング)回路(50)によりノイズが低減された後に、AGC(自動利得制御)回路(51)によりレベルが調整される。
FIG. 9 is an internal block diagram of a conventional digital camera. The photographic lens (21) has a drive mechanism (
(Not shown) is movable along the optical axis, and the image of the subject is connected to the CCD (5) through the diaphragm (54) by the photographing lens (21). The CCD (5) is controlled by a driver circuit (56), converts the received optical signal into an image signal which is an electrical signal, and outputs the image signal, which is output by a CDS (correlated double sampling) circuit (50). After the noise is reduced, the level is adjusted by an AGC (automatic gain control) circuit (51).

画像信号は、A/Dコンバータ(55)にてデジタル信号に変換され、信号処理部(52)にて黒レベルやホワイトバランスが調整された後に、制御手段であるCPU(1)に入力する。CPU(1)にはシャッタ釦(20)及び操作キーの信号が入力され、動画及び静止画の画像信号は画像圧縮処理部(53)にて圧縮されてメモリカード(4)内に格納される。動画及び静止画には、夫々異なる拡張子が付され、再生時には該拡張子により動画か静止画かを判断する。   The image signal is converted into a digital signal by the A / D converter (55), and after the black level and white balance are adjusted by the signal processing unit (52), the image signal is input to the CPU (1) as the control means. The CPU (1) receives the shutter button (20) and operation key signals, and the video and still image signals are compressed by the image compression processing unit (53) and stored in the memory card (4). . A moving image and a still image are given different extensions, and at the time of reproduction, it is determined whether the moving image is a moving image or a still image.

このような動画及び静止画の撮影ができる撮影装置においては、静止画像の撮影を行う際、高画質な画像の撮影が求められることが多い。そのため、CCD(5)は高解像度のものとなるように高画素化される。それに対して、動画の撮影を行う際には、NTSC(National Television System Committee)方式やPAL(Phase Alternation Line)方式などのアナログTV信号規格に準じた方式での撮影が求められるため、幾つかの画素を混合した低画素の画像を読み出す方法が提案されている。   In a photographing apparatus capable of photographing such moving images and still images, it is often required to photograph a high quality image when photographing a still image. Therefore, the CCD (5) has a high pixel count so as to have a high resolution. On the other hand, when shooting moving images, it is required to shoot with a method conforming to an analog TV signal standard such as NTSC (National Television System Committee) method or PAL (Phase Alternation Line) method. A method for reading out a low-pixel image in which pixels are mixed has been proposed.

図8は、CCD(5)の内部拡大図である(例えば、特許文献1参照)。CCD(5)は、水平及び垂直方向に配列されて、各画素の受光部を形成する複数のフォトダイオード(PD1)−(PD9)と、フォトダイオードにて形成される信号電荷を垂直方向に転送する複数の垂直転送路(8)(8)と、各垂直転送路(8)(8)から転送される信号電荷を水平方向に転送する水平転送路(80)と、該水平転送路(80)から転送される信号電荷を増幅する出力アンプ(81)を具える。各フォトダイオード(PD1)−(PD9)上には、入射光をフォトダイオード(PD1)−(PD9)に集光するマイクロレンズ(図示せず)が設けられている。   FIG. 8 is an enlarged view of the inside of the CCD (5) (see, for example, Patent Document 1). The CCD (5) is arranged in the horizontal and vertical directions, and transfers a plurality of photodiodes (PD1) to (PD9) that form the light receiving portions of the respective pixels and the signal charges formed by the photodiodes in the vertical direction. A plurality of vertical transfer paths (8) and (8), a horizontal transfer path (80) for transferring signal charges transferred from the vertical transfer paths (8) and (8) in the horizontal direction, and the horizontal transfer paths (80 ) Is provided with an output amplifier (81) for amplifying the signal charge transferred from the circuit. On each photodiode (PD1)-(PD9), a microlens (not shown) for condensing incident light onto the photodiodes (PD1)-(PD9) is provided.

各フォトダイオード(PD1)−(PD9)には、R、G、Bに対応したフィルタが設けられており、低画素の画像を表示するには、画素混合と呼ばれる方法が用いられる。これは、例えばフォトダイオード(PD1)−(PD9)の中の幾つかのフォトダイオードからは、Rに対応した信号電荷を読み出し、他の幾つかのフォトダイオードからは、G又はBに対応した信号電荷を読み出した後に、R、G、Bの信号電荷を混合して低画素の画像を生成し、読み出す方法である。これにより、画素を間引いて低画素の画像を作成するよりも感度を高めている。 高画素、特に最高画素の画像を撮影する際には、ドライバ回路(56)は全てのフォトダイオード(PD1)−(PD9)にて生成される信号電荷を垂直転送路(8)に送る。低画素の画像を撮影する際には、ドライバ回路(56)は画素混合にて生成した信号電荷を垂直転送路(8)に送る。   Each photodiode (PD1)-(PD9) is provided with filters corresponding to R, G, and B, and a method called pixel mixing is used to display a low-pixel image. For example, signal charges corresponding to R are read from some photodiodes in the photodiodes (PD1) to (PD9), and signals corresponding to G or B are read from some other photodiodes. In this method, after the charge is read out, R, G, and B signal charges are mixed to generate a low pixel image and read it out. As a result, the sensitivity is increased as compared with the case of creating a low-pixel image by thinning out pixels. When taking an image of a high pixel, particularly the highest pixel, the driver circuit (56) sends the signal charges generated by all the photodiodes (PD1)-(PD9) to the vertical transfer path (8). When taking an image of a low pixel, the driver circuit (56) sends the signal charge generated by the pixel mixture to the vertical transfer path (8).

高画素、低画素の何れの画像を映すかは、CPU(1)に入力される操作キーの信号によるが、動画の場合は前記の如く、低画素の画像が表示される。また、動画の場合は、フレーム数が多いと、処理する画素数が膨大となり、CCD(5)から電荷を読み出せない、又は信号処理ができないから、フレーム数を減らすこともある。
特開2003−234964号公報
Whether a high pixel image or a low pixel image is displayed depends on an operation key signal input to the CPU (1). In the case of a moving image, a low pixel image is displayed as described above. In the case of a moving image, if the number of frames is large, the number of pixels to be processed becomes enormous, and the number of frames may be reduced because charges cannot be read from the CCD (5) or signal processing cannot be performed.
JP 2003-234964 A

斯種デジタルカメラには、動画撮影を行っている間に、静止画を記録できるものがある。この場合、高画素で静止画を撮影すると、静止画の画素処理に時間が掛かるから、画素処理が行われている間、動画の撮影が止まる。その結果、動画が不連続で記録される。   Some of such digital cameras can record a still image while taking a moving image. In this case, if a still image is shot with high pixels, it takes time for the pixel processing of the still image. Therefore, the shooting of the moving image is stopped while the pixel processing is being performed. As a result, the moving image is recorded discontinuously.

動画撮影を行っている間に、静止画を撮影し、且つ動画を途切れなくするには、動画の記録画素と静止画の記録画素を同じく低画素にすることが考えられる(しかし、この場合
でも、動画の画像処理法と静止画の画像処理法が異なれば、動画が途切れる可能性がある)。或いは、動画のフレーム数を小さくして、動画の画素処理の時間を短くし、その分静止画の画素処理に余裕を持たせることも考えられる。
In order to shoot still images while shooting a movie and to keep the movie uninterrupted, it is conceivable that the recording pixels of the movie and the still image recording pixels should be set to the same low pixel. If the image processing method for moving images is different from the image processing method for still images, the moving image may be interrupted). Alternatively, it is conceivable to reduce the number of frames of the moving image to shorten the time for pixel processing of the moving image, and to give a margin to the pixel processing of the still image accordingly.

従来のデジタルカメラでは、動画撮影を行っている間に、動画が途切れてもよいから高画素で静止画を記録せんとする場合と、静止画を低画素で撮影してでも、動画を途切れないように撮影することを、使用者が選択することができず、使用者に不便なものであった。   With conventional digital cameras, the video may be interrupted while the video is being shot, so there is no need to record a still image with high pixels, and even if a still image is shot with low pixels, the video is not interrupted. Thus, it is inconvenient for the user because the user cannot select the shooting.

本発明の目的は、静止画のサイズ(画素数データ)や動画のフレーム数を選択することにより、動画の連続性を保つ場合と、連続性を保たなくともよい場合を選択できる撮影装置を提供することにある。   An object of the present invention is to provide a photographing apparatus that can select a case where the continuity of a moving image is maintained and a case where it is not necessary to maintain the continuity by selecting the size of the still image (pixel number data) and the number of frames of the moving image. It is to provide.

撮影装置は、キャビネット(2)内に、被写体画像を信号電荷に変換する固体撮像素子と、該固体撮像素子に繋がって動画撮影時には静止画撮影時よりも低画素の信号電荷を固体撮像素子から読み出すことができるドライバ手段と、該ドライバ手段に繋がってドライバ手段を制御する制御手段を設け、動画撮影中に静止画撮影可能である。   In the cabinet (2), a solid-state image pickup device that converts a subject image into signal charges and a signal charge of a lower pixel are connected to the solid-state image pickup device from the solid-state image pickup device during moving image shooting. A driver unit that can be read out and a control unit that is connected to the driver unit and controls the driver unit are provided, and still image shooting is possible during moving image shooting.

制御手段はメモリ手段及び報知手段に繋がり、メモリ手段内には少なくとも使用者が選択可能な静止画の画素数データと、単位時間当たりの動画撮影枚数と、選択された単位時間当たりの動画撮影枚数にて動画撮影中に、選択された画素数データにて静止画を撮影した際の動画の連続性情報が格納され、
制御手段は、静止画の画素数データ又は単位時間当たりの動画撮影枚数が選択された際に、該静止画の画素数データ又は単位時間当たりの動画撮影枚数に対応した動画の連続性情報を報知手段に伝達し、報知手段を作動させる機能を有する。
The control means is connected to the memory means and the notification means, and at least the number of still picture pixels selectable by the user in the memory means, the number of moving picture shots per unit time, and the number of moving picture shots per unit time selected Stores the continuity information of the movie when shooting a still image with the selected pixel number data during movie shooting at
The control means notifies the continuity information of the moving image corresponding to the pixel number data of the still image or the moving image shooting number per unit time when the pixel number data of the still image or the moving image shooting number per unit time is selected. It has the function to transmit to a means and to operate | move an alerting | reporting means.

本発明にあっては、報知手段が示した動画の連続性情報の内容から、静止画又は動画の撮影前に、動画撮影中に、動画が途切れてもよいから高画素で静止画を記録せんとする場合と、静止画を低画素で撮影してでも、動画を途切れないように撮影することを選択することができる。これにより、誤って動画を途切れさせる虞れを事前に防止でき、使用者にとって便利である。   In the present invention, from the content of the continuity information of the moving image indicated by the notification means, the moving image may be interrupted during moving image shooting before shooting the still image or moving image. In this case, even when a still image is shot with low pixels, it can be selected to shoot a moving image without interruption. Thereby, it is possible to prevent in advance the possibility of accidentally interrupting the moving image, which is convenient for the user.

1A and 1B are perspective views of a digital camera according to this example. FIG. 2 is a perspective view of an example digital camera related to the dependent claims of the present invention. An auxiliary cabinet (3) is connected to the cabinet (2) by a hinge (30). The auxiliary cabinet (3) is rotated around the hinge (30) in the direction of arrow A in FIG. When rotated in the direction, the display (22) provided on the back surface of the auxiliary cabinet (3) is exposed as shown in FIG. 1 (b). A zoom button (24), SET button (25), and MENU button (26) are provided on the cabinet (2) as is well known. When the MENU button (26) is pressed, a menu is displayed on the display (22). Then, the contents of the menu can be selected with the SET button (25).

図2に示すように、キャビネット(2)上には、動画撮影用の第1レリース釦(6)と、高画素の静止画を撮影用の第2レリース釦(60)と、低画素の静止画を撮影用の第3レリース釦(61)とが配備されている。キャビネット(2)は片手で把持できる大きさであり、右手でキャビネット(2)を把持した場合、第1レリース釦(6)及び第3レリース釦(61)は、親指で操作でき、第2レリース釦(60)は人差し指で操作できる。全てのレリース釦(6)(60)(61)を片手で操作でき、便利である。   As shown in FIG. 2, on the cabinet (2), a first release button (6) for moving image shooting, a second release button (60) for shooting a high pixel still image, and a low pixel still image A third release button (61) for taking a picture is provided. The cabinet (2) has a size that can be held with one hand. When the cabinet (2) is held with the right hand, the first release button (6) and the third release button (61) can be operated with the thumb and the second release. The button (60) can be operated with an index finger. All the release buttons (6) (60) (61) can be operated with one hand, which is convenient.

図3は、ディスプレイ(22)の画面を示す図である。ディスプレイ(22)上には、静止画情報を示す第1アイコン(9)と、動画情報を示す第2アイコン(90)とが表示される。使用者はMENU釦(26)、SET釦(25)を操作して、静止画情報を示す第1アイコン(9)を選択すれば
、撮影すべき静止画の画素数データが表示される。また、第2アイコン(90)を選択すれば、撮影すべき動画のフレーム数(1秒間当たりの画像枚数で単位がfps)が表示される。尚、第1アイコン(9)及び第2アイコン(90)は、図3に示す位置、図形に限定されず、適宜変更可能である。
FIG. 3 is a diagram showing a screen of the display (22). A first icon (9) indicating still image information and a second icon (90) indicating moving image information are displayed on the display (22). If the user operates the MENU button (26) and the SET button (25) to select the first icon (9) indicating still image information, the pixel number data of the still image to be photographed is displayed. If the second icon (90) is selected, the number of frames of the moving image to be shot (the number of images per second, the unit is fps) is displayed. Note that the first icon (9) and the second icon (90) are not limited to the positions and figures shown in FIG.

図4は、本例に係わるデジタルカメラの内部ブロック図である。CCD(5)は、ドライバ回路(56)にて制御され、受けた光信号を電気信号である画像信号に変換して出力し、該画像信号はCDS(相関二重サンプリング)回路(50)によりノイズが低減された後に、AGC(自動利得制御)回路(51)によりレベルが調整される。画像信号は、A/Dコンバータ(55)にてデジタル信号に変換され、信号処理部(52)にて黒レベルやホワイトバランスが調整された後に、制御手段であるCPU(1)に入力する。CPU(1)にはシャッタ釦(20)及び操作キーの信号が入力され、動画及び静止画の画像信号は画像圧縮処理部(53)にて圧縮されてメモリカード(4)内に格納される。この点は、従来と同様である。   FIG. 4 is an internal block diagram of the digital camera according to this example. The CCD (5) is controlled by a driver circuit (56), converts the received optical signal into an image signal which is an electrical signal, and outputs the image signal, which is output by a CDS (correlated double sampling) circuit (50). After the noise is reduced, the level is adjusted by an AGC (automatic gain control) circuit (51). The image signal is converted into a digital signal by the A / D converter (55), and after the black level and white balance are adjusted by the signal processing unit (52), the image signal is input to the CPU (1) as the control means. The CPU (1) receives the shutter button (20) and operation key signals, and the video and still image signals are compressed by the image compression processing unit (53) and stored in the memory card (4). . This is the same as in the prior art.

ドライバ回路(56)は、動画撮影時には静止画撮影時よりも低画素の信号電荷をCCD(
5)から読み出すことができ、具体的には、前記の画素混合により、動画は1フレームが
30万画素に圧縮されて読み出される。勿論、動画は1フレームが30万画素に限定されない。
The driver circuit (56) receives a lower pixel signal charge when shooting a moving image than when shooting a still image.
5), specifically, by the above-described pixel mixture, a moving image is read with one frame compressed to 300,000 pixels. Of course, a moving image is not limited to 300,000 pixels per frame.

CPU(1)には、メモリ(7)及び前記ディスプレイ(22)が接続される。メモリ(7)には図5の表に示す如く、使用者が選択可能な静止画のサイズ、即ち画素数データと、動画フレーム数と、選択された動画フレーム数にて動画撮影中に、選択された画素数データにて静止画を撮影した際の動画の連続性情報が予め格納されている。   The CPU (1) is connected to the memory (7) and the display (22). In the memory (7), as shown in the table of FIG. 5, the size of the still image that can be selected by the user, that is, the number of pixel data, the number of moving image frames, and the selected number of moving image frames is selected during moving image shooting. The continuity information of a moving image when a still image is taken with the pixel number data is stored in advance.

動画の連続性情報とは、具体的には、動画撮影中に静止画を撮影した際に、動画が途切れることなく撮影されることが可能か否かの情報である。また、動画は640×480ドットのVGA(Video Graphics Array)サイズにて表示されるが、このサイズに限定されない。更に、図5の表の情報は、デジタルカメラの取扱説明書にも記載されており、使用者が該取扱説明書を見ることにより、動画撮影中に静止画を撮影した際に、動画が途切れることなく撮影されるか否かが判る。   Specifically, the moving image continuity information is information indicating whether or not a moving image can be taken without interruption when a still image is taken during moving image shooting. In addition, the moving image is displayed in a 640 × 480 dot VGA (Video Graphics Array) size, but is not limited to this size. Furthermore, the information in the table of FIG. 5 is also described in the instruction manual of the digital camera, and the user sees the instruction manual, and when the user takes a still image while shooting the movie, the movie is interrupted. You can tell whether or not you can shoot without it.

動画を撮影中に、静止画を撮影した際に、動画が途切れないか否かは、CCD(5)からの電荷を読み出す速度、又は信号処理速度によって決定される。例えば、フレーム数が30fpsで動画を撮影中に、500万画素で静止画を撮影せんとしても、静止画の膨大な画素に対応した電荷をCCD(5)から読み出すには時間が掛かるから、動画は途切れる。   Whether or not the moving image is interrupted when a still image is shot during shooting of the moving image is determined by the speed at which the charge from the CCD (5) is read or the signal processing speed. For example, even when shooting a still image with 5 million pixels while shooting a movie with a frame number of 30 fps, it takes time to read out the charge corresponding to the huge pixels of the still image from the CCD (5). Is interrupted.

これに対し、フレーム数が15fpsで動画を撮影中に、30万画素で静止画を撮影する
場合には、静止画に対応した電荷をCCD(5)から読み出すには余裕があり、動画は途切れない。尚、図5の表に示した静止画のサイズ及び動画フレーム数は、説明の便宜上の一例であり、これに限定されない。
On the other hand, when shooting a still image with 300,000 pixels while shooting a movie with a frame number of 15 fps, there is room to read the charge corresponding to the still image from the CCD (5), and the movie is interrupted. Absent. Note that the size of the still image and the number of moving image frames shown in the table of FIG. 5 are examples for convenience of description, and are not limited to these.

本例の動作を図6のフローチャートを用いて説明する。予め動画のフレーム数は選択されているとする。   The operation of this example will be described with reference to the flowchart of FIG. It is assumed that the number of frames of the moving image has been selected in advance.

電源がONされた後に(S1)、CPU(1)は、使用者が高画素の静止画撮影用の第2レ
リース釦(60)を押したか否かを検索する(S2)。第2レリース釦(60)が押されれば、選択
された動画のフレーム数が高いか否かを、メモリ(7)内の図5の表に基づいて判断する(
S3)。例えば、動画のフレーム数が30fpsのときに、動画撮影中に500万画素の静止

アイコン(90)を所望の色に点灯又は点滅させる。
After the power is turned on (S1), the CPU (1) searches for whether or not the user has pressed the second release button (60) for photographing a high-pixel still image (S2). If the second release button (60) is pressed, it is determined based on the table of FIG. 5 in the memory (7) whether the number of frames of the selected moving image is high (see FIG. 5).
S3). For example, when the number of frames of a moving image is 30 fps, the moving image is interrupted even if a still image of 5 million pixels is shot during moving image shooting. The CPU (1) sends a signal indicating that the moving image is interrupted to the display (22), and the display (22) displays this (S6). For example, the second corresponding to the video
The icon (90) is turned on or blinked in a desired color.

ステップS2にて、高画素で静止画を撮影しない、即ち低画素の静止画撮影用の第3レ
リース釦(61)が押された場合は、動画が連続して撮影され得るか否かを判断する(S4)。
動画が連続して撮影され得ない場合は、動画が途切れる旨をディスプレイ(22)に表示する(S6)。
In step S2, if a still image is not photographed with high pixels, that is, if the third release button (61) for photographing a low pixel still image is pressed, it is determined whether or not a moving image can be continuously photographed. (S4).
If the moving image cannot be continuously shot, a message that the moving image is interrupted is displayed on the display (22) (S6).

ステップS4にて、静止画を撮影しても動画が連続して撮影され得ると判断されれば、
その旨をディスプレイ(22)上に表示する(S5)。例えば、動画のフレーム数が30fpsのときに、動画撮影中に30万画素の静止画を撮影しても、動画は途切れないから、その旨を表示する。
If it is determined in step S4 that a video can be continuously shot even if a still image is shot,
A message to that effect is displayed on the display (22) (S5). For example, when the number of frames of a moving image is 30 fps, even if a still image of 300,000 pixels is shot during moving image shooting, the moving image is not interrupted, so that effect is displayed.

この動画の連続性が保たれる場合は、使用者の更なる操作を待たずに、選択された動画の画素数で、自動的に動画を連続的に撮影できるように設定してもよい。   When the continuity of the moving image is maintained, it may be set so that the moving image can be automatically and continuously shot with the number of pixels of the selected moving image without waiting for further operation by the user.

本例にあっては、ディスプレイ(22)が示した動画の連続性情報の内容から、静止画又は動画の撮影前に、動画撮影中に、動画が途切れてもよいから高画素で静止画を記録せんとする場合と、静止画を低画素で撮影してでも、動画を途切れないように撮影することを選択することができる。これにより、誤って動画を途切れさせる虞れを事前に防止でき、使用者にとって便利である。   In this example, from the content of the continuity information of the moving image shown on the display (22), the moving image may be interrupted during moving image shooting before shooting the still image or moving image. When recording is to be performed, it is possible to select to capture a moving image without interruption even when a still image is captured with low pixels. Thereby, it is possible to prevent in advance the possibility of accidentally interrupting the moving image, which is convenient for the user.

上記の記載では、動画が連続して撮影可能か否かを示す報知手段として、ディスプレイ(22)を示したが、例えばブザー、チャイム等で示すことも可能である。   In the above description, the display (22) is shown as an informing means for indicating whether or not a moving image can be continuously shot.

また、固体撮像素子として、CCD(5)を例示したが、C−MOSでもよい。   Further, although the CCD (5) is exemplified as the solid-state imaging device, it may be a C-MOS.

上記実施例の説明は、本発明を説明するためのものであって、特許請求の範囲に記載の発明を限定し、或は範囲を減縮する様に解すべきではない。又、本発明の各部構成は上記実施例に限らず、特許請求の範囲に記載の技術的範囲内で種々の変形が可能であることは勿論である。   The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof.
