Abstract:
1. An image processing device comprising: horizontal processing circuitry configured to take, as an object of processing, a first thinned-out image obtained by thinning out pixels of a first image in an oblique direction, and a second thinned-out image obtained by thinning out pixels of a second image which differs from the first image in an oblique direction, and perform horizontal packing in which, as horizontal processing for manipulating the array of pixels in the horizontal direction, pixels of said first thinned-out image and pixels of said second thinned-out image are packed in the horizontal direction; combining circuitry configured to generate, as an encoding object image to serve as the object of prediction encoding, a combined image in which said first thinned-out image and said second thinned-out image subjected to horizontal packing by said horizontal processing are arrayed adjacently; and vertical processing circuitry configured to take, as an object of processing, of said first thinned-out image and said second thinned-out image subjected to horizontal packing by said horizontal processing circuitry, separate odd lines and even lines from said first thinned-out image and said second thinned-out image subjected to horizontal packing by said horizontal processing circuitry, and generate post-vertical processing images including an image in which only said odd lines are arrayed and an image in which only said even lines are arrayed, as vertical processing to manipulate the vertical direction array of the pixels; wherein said combining circuitry generates said combined image by adjacently arraying said post-vertical processing images.
