Patent ID: 7450166

Claim:
An apparatus for processing a digital signal in an image sensor, comprising: a line memory means for storing an inputted digital signal of red (R), green (G) and blue (B); a kernel generation means for generating a plurality of kernels after receiving the RGB digital signal from the line memory means; a false color detection means for detecting false colors by using the plurality of kernels; an edge detection means for detecting edges by using the plurality of kernels; an interpolation means for interpolating the RGB digital signal from the line memory means; a color space conversion means for converting the interpolated RGB digital signal into a YCbCr signal; and an image enhancement means for suppressing the false colors and enhancing the edges in the YCbCr signal in response to outputs of the false color detection means and the edge detection means wherein the false color detection means uses a portion of the plurality of the kernels to detect the false colors and the edge detection means uses another portion of the plurality of the kernels to detect the edges.
