Abstract:
1. An imaging system, comprising: an image sensor having an array of image sensor pixels, wherein the array of image sensor pixels includes red image sensor pixels configured to generate red image signals in response to red light, blue image sensor pixels configured to generate blue image signals in response to blue light, and clear image sensor pixels configured to generate white image signals in response to at least red light, green light and blue light; and processing circuitry configured to perform filtering operations on the red image signals, the blue image signals, and the white image signals that increase noise correlations associated with red image signals, the blue image signals, and the white image signals, wherein the processing circuitry is configured to perform the filtering operations on the red, blue, and white image signals that increase the noise correlations associated with the red, blue, and white image signals such that noise fluctuations in the red, blue, and white image signals increase and decrease together in a correlated manner.
