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： In the case where an input signal is an interlace signal such as NTSC signal, a flicker interference as aliasing interference brought about by the sampling theorem is contained in a region where a vertical frequency component is high. Accordingly, in the conventional processing in which rate of change in gradation is improved by making a drive voltage of liquid crystal at the time of change in gradation larger than normal liquid crystal drive voltage to increase response rate of the liquid crystal panel, interference component is also emphasized. As a result, quality level of a video picture to be displayed on the liquid crystal panel is deteriorated. The invention provides a compensation device capable of improving rate-of-change in gradation at a part where there is no flicker interference and changing rate-of-change in gradation to suppress the flicker at a part where there is any flicker interference.

摘要： A coding circuit codes present image data of a pixel which is received as raster data and a delay circuit stores a coded image data for one frame period and outputs one-frame preceding image data of the pixel in accordance with an input of the coded image data. First and second decoder circuits decode coded image data and one-frame preceding coded image data, respectively, a variation-amount calculation circuit calculates variation-amount data of both decoded image date, and an one-frame preceding image reproduction circuit reproduces one-frame preceding reproduced image data. An image date correction circuit generates corrected present image data on the basis of the present image data and the one-frame preceding reproduced image data.

摘要： In the image processors and the image processing methods of the present invention, the number of bits for quantizing image data is adjusted on the basis of a dynamic range of each block. Therefore, the error introduced by encoding is reduced without increasing the data amount of the encoded image data, and the response speed of a liquid crystal can be controlled appropriately by preventing unnecessary voltages from being applied due to the error introduced by encoding.
