See full text

An image processing apparatus sections an image to be processed into a plurality of blocks, rearranges the blocks into positions specified by an encryption key that uniquely specifies the positions of the blocks in the image, determines a computing method used to convert pixel values of pixels that form a minimum area included in each of the blocks after the blocks are rearranged based on the pixel values of predetermined pixels that do not belong to the minimum area, and converts the pixel values based on the computing method.
