converter with at least two photosensitive halbleiterelementen

摘要

A photosensitive semiconductor array includes a plurality of photodiodes with separate output electrodes and color filters overlaying each photodiode. Each of the photodiodes, when simultaneously exposed to a point source of image bearing multicolored light focused on the photodiode array, responds by producing signals at its output terminals. The size of each photodiode and the filters overlaying same may be altered to change the response thereof. The photodiode array is useful in translating a light beam scanning motion picture film frames into red, green and blue color signals.
