1. A method of processing an array of pixels captured by an image capture device, 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) a processing stage for determining in response to ambient lighting conditions, whether panchromatic pixels are to be combined with color pixels;
(c) combining pixels determined from step (b) to produce a second two-dimensional array of pixels which has fewer pixels than the first two-dimensional array of pixels; and
(d) correcting the color pixels produced in step c.

Abstract
A method of processing an array of pixels captured by an image capture device, having 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; determining in response to ambient lighting conditions, whether panchromatic pixels are to be combined with color pixels; combining pixels to produce a second two-dimensional array of pixels which has fewer pixels than the first two-dimensional array of pixels; and correcting the color pixels.

13. A method of converting a high resolution color digital image captured by a electronic sensor into a lower resolution color digital image, including:
-
(a) using the electronic sensor to capture a first two-dimensional array of pixels; (b) analog combining pixels in the first two-dimensional array of pixels to produce a second two-dimensional array including at least some composite pixels and also having non-regular spacing; (c) using a processing stage for computing a third two-dimensional array of pixels with regular spacing; and (d) correcting the regularized third two-dimensional array of pixels to produce a corrected image with reduced artifacts. - View Dependent Claims (14)
