IMAGE PROCESSOR

An image processor processes an image having color pixels (R, G, B) arranged in a Bayer pattern. The image processor provides a de-correlated image composed of three types of components (Y, Cr, Cb). The image processor provides a component of the first type (Y) as a substitute for a pixel of the fir...

Beschreibung
Zusammenfassung:	An image processor processes an image having color pixels (R, G, B) arranged in a Bayer pattern. The image processor provides a de-correlated image composed of three types of components (Y, Cr, Cb). The image processor provides a component of the first type (Y) as a substitute for a pixel of the first type (G), whereby the component of the first type (Y) is a weighted combination of a cluster of pixels that includes the pixel of the first type (G) and neighboring pixels, wherein neighboring pixels of the second and third type (R, B) have an overall positive weighting factor corresponding to an overall addition of neighboring pixels of the second and third type (R, B) to the pixel of the first type (G). The image processor also provides a component of the second type (Cr) and a component of the third type (Cb) in similar fashion.
