Abstract
An image data processing apparatus wherein patterns obtained on the basis of common image information shared by a plurality of pre-conversion pixels with one post-conversion pixel are stored in a calculation data selector, and there is decided a pattern conforming with the pixel data inputted to the calculation data selector via an A/D converter and a frame memory. A calculation coefficient selector selects the calculation coefficients corresponding to the pattern thus decided, and outputs the selected coefficients to a calculator. Then the calculator calculates new pixel data by the use of such calculation coefficients and pixel data inputted thereto. In this apparatus, the post-conversion image formed by converting the number of its pixels can be displayed clearly.
