发明名称 Color page scanner using fiber optic bundle and a photosensor array
摘要 A color image scanner comprises a noncoherent fiber optic bundle having a linear entrance face and an area exit face coupled to an array of photosensors. The density of sensors of the array is such that each fiber end in the exit face corresponds to a plurality of sensors. A striped (RGB) color filter positioned between the exit face and the sensor array permits a sensor to be selected for each color for each pixel in the entrance face. The addresses of the three sensors for each pixel are stored in a lookup table in a proper sequence to correspond to the proper pixel sequence in the entrance face. The addresses are stored in sequence in ROM and the sequence is triggered for each of the consecutive scan lines of a page being scanned. Thus, color scanner operation is achieved with a monochrome photosensor array in the absence of time-sequential color illumination.
