Abstract
In an image processing device, image data is buffered by an image buffer section to output an interested pixel value and surrounding pixel values of a pixel surrounding an interested pixel. A shift condition determination section determines on the basis of the interested pixel value and the surrounding pixel values whether or not the interested pixel value should be shifted, and outputs a shift determination result. A pixel shifting amount computing section computes the pixel shifting amount of the interested pixel, and the shifted pixel position calculation section outputs a shift pixel position signal on the basis of setting parameters Tx and Ty, and clock signals XCLOCK and YCLOCK. A pixel value shifting section outputs the interested pixel value after the shifting on the basis of the interested pixel value, a shift determination result, the pixel shifting amount, and the shift pixel position signal.
