Summary:PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of simply accelerating 2-dimensional filter processing. SOLUTION: An image color signal input unit 11 inputs an RGB signal as image data. A G edge-detection filter processor 14 is a two-dimensional filter means, and applies G edge-detection filter of a two-dimensional image processing filter to the image data. The filter processing is carried out by shifting in the order of a pixel an image data for the filter processing and corresponding to a filter processing range. An image data upside down reversal processor 16 is a reversal processing means, and reverse color signal location of the image data for filter processing and filter coefficient location of the two-dimensional image processing filter relatively up and down, whenever a filter processing object is shifted. The same two-dimensional image filter can be used due to the reversal process even if the filter processing object shifts. Accordingly, filter switching is unnecessary. COPYRIGHT: (C)2008,JPO&INPIT
