ABSTRACT:
A pixel signal of Bayer pattern output from an imaging device is subjected to interpolation in a pixel interpolation circuit, and converted into a YCbCr signal in a color space conversion circuit. A chroma value calculation circuit calculates a chroma value based on the pixel signal output from the imaging device. A look-up table converts the chroma value into a suppression signal. More specifically, when the chroma value is lower than a threshold value, the look-up table outputs a value lower than 1 as the suppression signal. The suppression signal is corrected in another look-up table, and then, works on Cr and Cb signals in multipliers. A signal in a low-chroma region is thereby suppressed.
