Abstract
An image processing device, method, recording medium, and program where the device includes an image data continuity detector configured to detect continuity of image data made up of a plurality of pixels acquired by real world light signals being cast upon a plurality of detecting elements, and a real world estimating unit configured to estimate real world light signals by approximating image data with discontinuous functions.
Claims5
An image processing device comprising:
- an image data continuity detector configured to detect continuity of image data made up of a plurality of pixels acquired by real world light signals being cast upon a plurality of detecting elements, each having spatio-temporal integration effects, of which a part of continuity of said real world light signals have been lost;
- and
- a real world estimating unit configured to estimate said real world light signals by approximating said image data with discontinuous functions, assuming that pixel values of each pixel corresponding to a position in at least a one-dimensional direction out of spatio-temporal directions of said image data are the pixel values acquired by integrating of said at least the one-dimensional direction, corresponding to the image data continuity detected by said image data continuity detector.
