    摘要: An image processing circuit for driving a liquid crystal that encodes and decodes image data to reduce the size of the frame memory that, when it quantizes (45) each block of image data in the current frame and outputs encoded data, selects (44) a mean value on the basis of the dynamic range of each unit block and adjusts the amount by which the image data is reduced (53). This type of control enables it to reduce the amount of image data that must be temporarily stored in the delay circuit (5), so the size of the frame memory constituting the delay circuit can be reduced while minimizing the encoding error that occurs in the encoder (4). Consequently, the image data can be corrected accurately and appropriate voltage corrections can be applied to the liquid crystal without the effects of coding and decoding errors.

    摘要: An image signal representing consecutive video frames is resampled, using different sampling phases so that different subsets of pixels are taken from each frame in a consecutive set of frames. The resulting set of resampled frames is combined into a single frame and transferred to an image display unit that divides the single frame into subframes and displays the subframes sequentially with different pixel shifts. Each pixel in each subframe is displayed at its correct spatial and temporal position. Although the resampling process greatly reduces the pixel data transfer rate, the image display unit can reproduce still images without loss of definition and moving images without motion blur.
