Patent ID: 7319481

Claim:
A camera signal processing apparatus comprising: an interpolated pixel data generating means for interpolating pixel data in at least two directions based on a position of said pixel data andlor pixel data around said position, said pixel data being generated based on an imaging signal coming from a solid-state image sensor in which an imaging light enters through a color filter having a different spectral characteristic for each pixel, thereby separately generating interpolated pixel data in said at least two directions; a correlation detecting means for detecting a correlation value indicative of a degree of correlation in each of said at least two directions of said interpolated pixel data generated by said interpolated pixel data generating means; a color-difference signal detecting means for detecting a color-difference signal of each of said interpolated pixel data in each of said at least two directions generated by said interpolated pixel data generating means and interpolated pixel data added with said correlation value detected by said correlation detecting means in each of said at least two directions; a selecting means for selecting a smallest one of the color-difference signal of said interpolated pixel data in each of said at least two directions and the color-difference signal of the interpolated pixel data computed by use of said correlation value in each of said at least two directions; and an image generating means for generating an image based on the interpolated pixel data selected by said selecting means.
