Patent ID: 7573515

Claim:
A method for signal processing, wherein a sensor signal of an image sensor is provided as an input and wherein the input is reconstructed in a filter to establish an output for further processing, wherein the filter comprises at least one reconstruction-filter selected from the group consisting of: a luminance-reconstruction-filter, a red-green-blue-color-reconstruction-filter and a contour-reconstruction-filter, wherein the sensor signal comprises a plurality of pixels, and a pixel provides a color value assigned to at least one of the colors red, green or blue, characterized in that the method comprises the steps of: applying the reconstruction-filter to an array of pixels of predetermined array size comprising a number of pixels of said plurality of pixels, wherein at least one of the number of pixels is formed by a red-pixel assigned to the color of red, at least one of the number of pixels is formed by a blue-pixel assigned to the color of blue, and at least one of the number of pixels is formed by a green-pixel assigned to the color of green; weightening the red- and/or the blue-pixel by a green-parameter; summarizing the pixels of the array into one output-pixel; and centering the output-pixel in the array.
