Image Signal Processor Circuits and Methods for Correcting Crosstalk Artifacts

摘要

Methods and circuits can be provided to correct crosstalk artifacts by generating image data correction matrices for respective pixel locations in an image sensor, based on pre-calibration matrices associated with the respective pixel locations. The image data correction matrices can be applied to the respective pixel locations to reduce imaging crosstalk artifacts associated with at least one of disparity, luminance, and chrominance.

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