<p>A method and device for processing analog color signals, comprising: analog preprocessing (3) sensor output signals to obtain analog preprocessed signals that cause a reduced amount of digital quantization errors; converting (5) the analog preprocessed signals into digital signals; reconstructing (7) a first basic color signal (), a second basic color signal (), and a third basic color signal () from the digital signals; and correcting (9) the basic color signals to obtain standardized signals, in which a three color signal matrix containing the first, second and third basic color signals (, ,) is multiplied by a correction matrix containing coefficients that depend on the analog preprocessing (3). In a first embodiment, the analog preprocessing includes a white balance adjustment. In a second embodiment, the horizontal sum values of the correction matrix are adjusted to one for horizontal sum values larger than one, with the analog preprocessing comprising a corresponding multiplication in the analog preprocessing to ensure to the overall processing multiplication remains the same as in the prior art. The invention further relates to a color camera comprising an RGB Bayer sensor for generating the sensor output signals, and the above-mentioned processing device.</p> |
