— The image‐processing techniques used in a newly developed video printer are described. The amount of image data is reduced by subsampling the chrominance signals and by data compression. The DPCM algorithm is used for the compression. A field‐interpolation algorithm that takes into account the correlation between diagonal dots is proposed. This algorithm is simple and has better spatial‐frequency characteristics than the bi‐linear interpolation algorithm. A color‐signal‐conversion circuit that enables users to adjust the color, tint, contrast, and luminance after capturing an image is also described.
