Patent ID: 7595800

Claim:
An image processing device comprising: a region selecting unit configured to select a region corresponding to a pixel of interest which is a pixel within image data made up of a plurality of pixels acquired by light signals of a real world being cast upon a plurality of detecting elements each having spatio-temporal integration effects, of which a part of continuity of the light signals of the real world have been lost; a frequency detector configured to detect a frequency corresponding to pixels belonging to the region as well as setting the frequency thereof for each pixel according to a correlation value between pixel values of pixels of interest and pixel values of pixels according to the region selected by said region selecting unit; a continuity detector configured to detect data continuity of said image data corresponding to the continuity of said real world light signals which have been lost by detecting a regression line based on said frequency detected by said frequency detector, said continuity detector configured to detect the region having data continuity based on a standard deviation of an estimated error between said regression line and said frequency corresponding to the pixels belonging to the region; and a real world estimating unit configured to estimate said light signals by estimating the continuity of said real world light signals which have been lost, based on the data continuity of said image data detected by said continuity detector, said real world estimating unit configured to generate a second function approximating a first function which represents said real world light signals based on the region having said data continuity detected by said continuity detector.
