PRODUCING FULL-COLOR IMAGE USING CFA IMAGE
First Claim
1. A method of forming a full-color output image using a color filter array image having a plurality of color channels and a panchromatic channel, comprising one or more processor(s) for providing the following:
- a) capturing a color filter array image using a color filter array image sensor, the color filter array image having a plurality of color channels and a panchromatic channel, wherein the panchromatic channel is captured using a different exposure time than at least one of the color channels;
b) computing an interpolated color image and an interpolated panchromatic image from the color filter array image;
c) computing a chrominance image from the interpolated color image; and
d) forming the fall color output image using the interpolated panchromatic image and the chrominance image.
