[0047] Configuration of information processing device
[0048] figure 1 is a block diagram showing a first configuration example of the information processing apparatus 1 according to the first embodiment of the present invention.
[0049] An image compressed by Joint Photographic Experts Group (JPEG) compression that appears blurred due to hand shake at the time of shooting is an input blurred image to the information processing apparatus 1 .
[0050] The information processing apparatus 1 separates the input blurred image into a plurality of blocks g, and initially estimates, in each block, a point spread function h representing blur occurring in the block g and a point spread function h representing the block g having a large value, a flat portion, and an edge The structure of the components of f.
[0051] The information processing apparatus 1 repeatedly updates the point spread function h and the structure f ...
