20130258114 | DIGITAL PROCESSING FOR COMPENSATING SIGNALS EMITTED BY PHOTOSITES OF A COLOUR SENSOR - The present invention relates to the acquisition of colour images by a sensor including a plurality of photosites comprising spectral sensitivities that can to be different between photosites. The invention provides for a digital processing of signals emitted by the photosites, which comprises applying a spatial-chromatic transfer function to said signals, taking into account a variety of spectral sensitivities of the photosites. The sensor can then be devoid of a physical matrix of colour filters. Spectral calibration of the sensor is also provided for this purpose, thus comprising the following steps: obtaining spectral sensitivity data of each photosite (S | 10-03-2013 |
