Patent ID: 7750925

Claim:
A signal processing device comprising: a hardware sensor configured to detect a plurality of pixels; a movement vector setting unit configured to set movement vectors for an object within image data wherein a light signal of a real world is projected on the plurality of pixels, each having a time-space integration effect, and a portion of continuity of the light signal of the real world is lost; and a real world estimating unit configured to estimate a real world function, a pixel value of each pixel corresponding to a position in a predetermined one-dimensional direction of a spatial direction of image data is a pixel value acquired by the real world function corresponding to said real world light signals approximated with a spline function, the real world estimating unit configured to estimate the real world function by solving an equation representing that the pixel value is acquired by integrating a model as the moving spline function, which is moving in a time direction corresponding to said movement vector while phase-shifting, in said predetermined one-dimensional direction and the time direction.
