Patent ID: 7668393

Claim:
A signal processing device including: a data continuity detector configured to detect data continuity in image data made up of a plurality of pixels from which a part of the continuity has been lost of second real world light signals obtained by first real world light signals being cast onto a plurality of detecting elements each having time-space integration effects, the continuity of said second real world signals being that a cross-sectional shape of an object being detected is the same at arbitrary positions in a continuity direction, the data continuity detector detecting a data continuity function having a constant value along a direction corresponding to continuity of data, the data continuity function changed from continuity of the second real world light signals; an actual world estimating unit configured to generate a second function approximating a first function representing said second real world light signals, using the data continuity function with the constant value along the direction of continuity of data detected by said data continuity detector; and a pixel value generator configured to generate pixel values corresponding to pixels of a desired magnitude, by integrating said second function generated by said actual world estimating unit with a desired increment in said at least one dimension direction.
