Abstract
An image processing device, method, recording medium, and program where the device includes a simple-type angle detecting unit simply detects the angle as continuity using correlation from an input image. The device includes an input configured to input 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 light signals being cast in an optical low-pass filter.
Claims7
An image processing device comprising:
- an input configured to input 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 temporal integration effects, via an optical low-pass filter, of which a part of continuity of said real world light signals have been lost;
- and
- a real world estimating unit configured to estimate light signals being cast in said optical low-pass filter, with consideration for light signals being scattered and integrated in at least a one-dimensional direction out of spatial directions by said optical low-pass filter, said real world estimating unit configured to generate functions approximating said real world light signals, by estimating a plurality of real world functions, such that pixel values of pixels of interest, corresponding to a position in two different spatial directions out of the spatial directions of said image data, are acquired by integrating in the two different spatial directions each of the plurality of real world functions corresponding to the plurality of light signals scattered in a spatial direction by said optical low-pass filter to generate a plurality of integrated real world functions, the real world estimating unit configured to compute pixel values by adding together contributions from at least two of the plurality of integrated real world functions.
An image processing method comprising:
- inputting 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 temporal integration effects, via an optical low-pass filter, of which a part of continuity of said real world light signals have been lost;
- and
- estimating light signals being cast in said optical low-pass filter, with consideration for light signals being scattered and integrated in at least a one-dimensional direction out of spatial directions by said optical low-pass filter, said estimating including generating functions approximating said real world light signals, by estimating a plurality of real world functions, such that pixel values of pixels of interest, corresponding to a position in two different spatial directions out of the spatial directions of said image data, are acquired by integrating in the two different spatial directions each of the plurality of real world functions corresponding to the plurality of light signals scattered in a spatial direction by said optical low-pass filter to generate a plurality of integrated real world functions, the estimating including computing pixel values by adding together contributions from at least two of the plurality of integrated real world functions.
