Patent ID: 7602992

Claim:
An image processing device comprising: a setting unit to set an angle corresponding to a predetermined reference axis and a direction of continuity of data in 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 real world estimating unit to generate a second function approximating a first function representing real world light signals by approximating said image data, assuming that pixel values of said pixels corresponding to a position in at least two dimensional directions within said image data are pixel values acquired by integration effects in said at least two dimensional directions, said second function corresponding to said angle set by said setting unit; a pixel value generator to generate pixel values by integrating said second function generated by said real world estimating unit with desired increments; and a difference computer to compute a difference between the pixel values which are values integrating said second function generated by said real world estimating unit with increments corresponding to pixels of interest in said image data, and the pixel values of said pixels of interest.
