Description of the Invention: [Technical Field] The present invention is mainly an image display device, and more particularly, an image display device having a function of decoding compressed image data. [Prior Art] The frame rate (Franie Rate) of the display has been gradually improved. However, in order to make the image signal sources match each other, the true improvement of the image can be achieved, thus making the dynamic estimation of Estimation, ME and moving compensation ( Motion Compensation, MC) technology is highly valued. Frame rate conversion (Frame Rate c〇nversi〇n, FRC) is performed by MEMC technology to present the best image quality to make the broadcasted image smoother. Therefore, it is necessary to add motion prediction and motion compensation compensation (MEMC or Motion Estimation Motion Compensation) to the display to predict the frame insertion of the next frame' re-creation compensation. Therefore, the image display device according to an embodiment of the invention includes an image decoding unit that receives a compressed image data, decodes and generates one of the first frame rates. The first image data, wherein the first image data includes an image object information; a frame rate conversion unit generates a compensation frame according to the image object information, and interpolates the compensation frame to the first image data to generate a second image data of a second frame rate; and a display unit for outputting the second image data. An image display method according to an embodiment of the invention includes receiving a compressed image data, decoding the compressed image data, and generating one of the frame rates of a PNAI-SW-0306-TWXX/0814-A42550-TWf 4 201228403 The first search for you - '7V image, where μ ★ image object information; according to the above-mentioned image of a younger brother; interpolated the above complement h _ ' object information to generate a compensation frame; interpolation of the above compensation map pivot Object information generation - compensating the second frame rate - the second shadow 2 - image data to produce a material having a mussel #, and rotating out the second image frame of the second image rate = this = one implementation The example includes a stream receiving device, a beta media shirt image streaming display decoding unit, a decoding pressure: a compressed image stream, and an image rate-first image data, wherein the first image frame is generated. Object information; a picture of the pivot rate conversion _ ^ image data includes an image generation and compensation frame 'interpolation of the above complement: Figure ==, the cattle information production has a second picture pivot rate / said the first - image data to the image Turn-out unit, output The first - the image data; and [embodiment] data. The description below uses the following description of the present invention to illustrate that the basic outline of the present invention is not limited to the scope of the application, and the scope of the application is well defined. A block diagram of the image display insertion 100 according to an embodiment of the invention. The image display device 1 is mounted 110, and the frame rate conversion unit 120 is configured to dry up and display the image data (for example, ΜΡΕ Μ Μ Μ , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , = code early MPEG-4 or other reduced format), then decode the 2 data to generate the initial image data. The frame rate conversion unit receives the initial image data, and performs frame rate conversion ' ^ 'conversion' The compensation compensation frame to the initial image data is used to increase the PNAI-SW-0306-TWXX/0814-A42550-TWf 201228403 frame rate (for example, 24Hz to 60Hz, 50Hz to 60Hz, _z to 120Hz, 60Hz to 240Hz, etc.) The image data after the frame rate is increased is output to the display unit it 13G. Since the compressed image data is compressed, it usually has information of the image object in the display surface, for example, position or motion vector (montion vector) Therefore, the frame rate conversion table 120 can directly generate a compensation frame according to the image object information, so that the image picture is smoother, and no additional motion prediction is required for the image. In some embodiments, the frame rate conversion unit 12 〇 also generates an interpolation compensation frame according to the frame rate of the initial image data and the frame rate to be increased. For example, when the frame rate needs to be increased more. , it is necessary to interpolate more frames, and the difference between the compensation frames is small. Conversely, when the frame 4 rate needs to be improved less, more frames need to be interpolated, and the compensation frame changes greatly. In some embodiments of the present invention, the image display device 100 can be a multimedia video stream display device, and further includes a stream receiving device 140. The stream receiving device 140 receives a compressed video stream (eg, a digital television signal). The wireless network signal, the local area network signal, and the USB signal are decoded by the round-trip to the image decoding unit 110. The third figure is a method for displaying the image display device according to the first embodiment of the present invention. In the step S2〇2, the image code unit 110 receives the compressed image data (for example, MPEG-1, MPEG-2 MPEG-4 or other compressed processed format). In step _, the image Decoding unit 110 Decompressing the compressed image data to generate the initial image data 'where the initial image data has its image object on the display surface °: PNAI-SW-〇3〇6-TWXX/〇8i4-A42550-TWf 6 201228403 image object information (for example, The position or movement vector is output to the frame rate conversion unit 120. In step S206, the frame rate conversion unit 120 generates a compensation frame according to the image object information. For example, the frame rate conversion unit 120 may be based on the image object. The motion vector in the message produces a compensation frame. In step S208, the compensation frame is interpolated to the initial image data to generate the interpolated image data, so that the image data is more continuous and smooth after the frame rate conversion. In step S210, the display unit 130 outputs the image data after the interpolation. Since the image object information generated by the compressed image data solution is directly used in the frame rate conversion stage, the frame can be directly output to the display unit without performing image motion prediction to generate compensation, and thus Achieve smoother image playback and save on the cost of motion prediction and Motion Estimation Motion Compensation (MEMC). The present invention has been described in terms of preferred embodiments, and is not intended to limit the embodiments of the invention. Rather, it encompasses a variety of variations and similar configurations (as will be apparent to those skilled in the art). In addition, the following broadest interpretation should be made in accordance with the scope of the appended claims to cover all such variations and similar configurations.
