    Abstract: 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.

    Abstract: Interpolation data for a missing pixel are obtained (4) after a correction (3) for variations in the characteristics of the imaging devices (8(1), 8(2)). The correction for variations in characteristics includes, for example, a black level correction (9) and a sensitivity correction (10). The interpolation includes, for example, interpolation calculations (14(1), 14(2)) such that a mean value of a plurality of pixels including the missing pixel and a mean value of a plurality of pixels not including the missing pixel become equal and an interpolation calculation (14(0)) that takes the mean of the pixels to the right and left of the missing pixel, the calculation with the least error being selected (13, 15). Thus missing pixels in highly periodic images can be properly interpolated, and interpolation can be performed with high precision even when there are variations in the sensitivity characteristics of the individual imaging devices constituting the contact image sensor.

    Abstract: A color conversion apparatus receives red-green-blue color data, calculates characteristic information and first hue region data from the color data, adjusts the first hue region data according to the characteristic information to obtain second to N-th hue region data, N being an integer equal to or greater than three, generates matrix coefficients for the second to N-th hue region data, and performs a matrix operation on the second to N-th hue region data to obtain color data with four or more color components. Color data with three primary components are thereby converted to color data with four or more primary components by simple calculations, without using a large amount of memory space.

    Abstract: 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.
