Abstract:
1. An image processing system for dynamically correcting color cross-talk and/or green disparity in pixel outputs in an image sensor, comprising: the image sensor, wherein the image sensor comprises at least a pixel array, an array of micro-lenses, and an array of color filters, and wherein: means for receiving analog outputs from each pixel in the pixel array; means for converting the received analog outputs to digital outputs; means for retrieving a selected digital output from a selected pixel on the pixel array and neighboring digital outputs from pixels neighboring the selected pixel, wherein the neighboring pixels comprise a left pixel located horizontally appurtenant to and on the left hand side of the selected pixel, a right pixel located horizontally appurtenant to and on the right hand side of the selected pixel, an upper pixel located vertically appurtenant to and directly above the selected pixel, and a down pixel located vertically appurtenant to and directly below the selected pixel; means for calculating a first digital average of the digital outputs from the left pixel and the right pixel; means for calculating a second digital average of the digital outputs from the upper pixel and the down pixel; means for processing a hyperbolic location for the scanned pixel, wherein the hyperbolic location is determined relative to a reference location on the pixel array; means for determining a color cross-talk correction factor for the selected pixel, wherein: means for correcting the selected digital output with the correction factor.
