Abstract
A method of directly obtaining a Y value for a luminance/chrominance representation of a scanline of a color scanned image produced by a color contact image sensor device having a linear sensor array to collect reflected light, wherein said contact image sensor device comprises red, green and blue light sources and wherein an optimal on time for each of the light sources is calibrated, the method comprising the step of illuminating the scanline during a single pulse independently with the red, the green and the blue light sources and allowing the linear sensor array to accumulate the reflected light from all of the light sources.
