Abstract

A method of processing a digital image having a predetermined color pattern, includes converting the predetermined color pattern of the digital image into a converted digital image having a different desired color pattern; and using algorithms adapted for use with the desired color pattern for processing the converted digital image.

Claims

1. A method of processing a digital image having a predetermined color pattern, comprising:

(a) converting the predetermined color pattern of the digital image into a converted digital image having a different desired color pattern; and

(b) using algorithms adapted for use with the desired color pattern for processing the converted digital image.

2. The method of claim 1 wherein step (a) includes interpolating color pixels in the predetermined color pattern to provide color pixels in the desired color pattern.

3. The method of claim 2 wherein the desired color pattern is a Bayer pattern.

8. The method of claim 1 where the processing further comprises:

(a) providing a panchromatic or derived panchromatic image and a full color image; and

(b) using the panchromatic derived panchromatic image for enhancement of the full color image.

4. A method of processing a digital image having a predetermined color pattern, comprising:

(a) providing a first two-dimensional array of pixels from the image capture device, some of which are color pixels, and some of which are panchromatic pixels;

(b) converting the digital image having the predetermined color pattern into a converted digital image having a different desired color pattern; and

(c) using algorithms adapted for use with the desired color pattern for processing the converted digital image.

5. The method of claim 4 wherein the desired color pattern is a Bayer pattern.

6. The method of claim 4 wherein the predetermined color pattern has a repeating unit of:

7. The method of claim 4 wherein the predetermined color filter array pattern has a repeating unit of:

9. The method of claim 4 wherein the predetermined color pattern has a repeating unit of:

10. The method of claim 4 wherein the predetermined color pattern has a repeating unit of:

11. A method of processing a digital image having a predetermined color pattern, comprising:

(a) providing a first two-dimensional array of pixels from the image capture device, some of which are color pixels, and some of which are panchromatic pixels;

(b) converting the digital image having the predetermined color pattern into a converted digital image having a different desired color pattern having pixels with three different effective spectral sensitivities; and

(c) using algorithms adapted for use with the desired color pattern for processing the converted digital image.

12. The method of claim 11 where the desired color pattern in step (b) is a Bayer pattern.
