1. A method for correcting crosstalk artifacts in an image signal processor circuit, the method comprising: performing an interpolation operation using color values of neighbor pixels to obtain interpolated color values at a current pixel in an image sensor; determining first matrix coefficients of a first matrix; and performing a first multiplication operation, using the image signal processor circuit, between the interpolated color values and the first matrix to correct disparity between the current pixel and the neighbor pixels in an image sensor independent of correcting chromaticity between the current pixel and the neighbor pixels and Luma between the current pixel and the neighbor pixels.
