  • Architecture for color space transformation to compensate for relative chip-to-chip spectral variations on a butted full-width array sensor bar
    Patent number: 6266438
    Abstract: A color space transformation device includes a sensor bar. The sensor bar includes a plurality of sensor chips. Each sensor chip scans a unique section of an original image to produce first data in a first color space. A memory means stores groups of coefficients. Each group of coefficients corresponds to one of the sensor chips. A processor independently transforms each of the sections of the first data to a respective section of a second data. The transformation is performed as a function of one of the groups of coefficients corresponding to the sensor chip which produced the first data.
