ABSTRACT:
A method and system for image chroma suppression of an image sensor system. Chroma suppression is performed to reduce the false color phenomena. The amount of chroma suppression is performed based on the strength of spatial frequency for a current processing pixel measured during edge detection. In determining the strength of spatial frequency of the current processing pixel, only a small number of green pixel values are needed, regardless of whether or not the current processing pixel is a green pixel within the Bayer pattern. As such, line buffers from the color interpolation module of an image sensor system can also be used for the purpose of chroma suppression.
