Patent Images

1. a color image sensor, including:

  • Pel array, it chromatic filter including covering the array for the optical sensor obtaining color image dataWhat array CFA, wherein said CFA included covering first group in described optical sensor has the first of the first colorSecond pseudo-colour filtering with the second color of second group in color filter component and the described optical sensor of coveringDevice element, wherein first group of optical sensor produces first chrominance signal with the first color channel, and second groupOptical sensor produces has the second chrominance signal of the second color channel, each grand in wherein said pel arrayPixel groups comprises the single pixel with the first color filter component and the list with the second color filter componentIndividual pixel;

    Chrominance signal combination device circuit CSCC, it is coupled to be received from described the first of described pel array outputChrominance signal and described second chrominance signal, described CSCC includes multiplier circuit, and described multiplier circuit is through couplingClose, described first chrominance signal and described second chrominance signal to be multiplied to produce, there is the of third color channelThree chrominance signals;

    Output port, it is defeated with the described color image data that will have three color channel that it coupled to described CSCCGo out outside described color image sensor.
