A single integrated-circuit color camera chip is color sensitive by grouping closely-adjoining light-detecting cells in a photodiode array into triplets. Each pixel of the sensor includes both a read transistor and a write transistor. Each cells in the triplet is similar, but each cell is associated with a color filter of a different color, with red, green or blue cells in an R-G-B system. The proximity and small size of the cells in a triplet allows accurate color differentiation each pixel. Color information is adjusted on-chip for color, brightness and contrast before being sent to an external read device or display device. The color filter is a series of passive layers formed on the integrated circuit surface permitting the selective transmission of light or electromagnetic radiation of certain frequency ranges. The filter may be coated onto a semiconductor wafer after the latter has undergone conventional MOS process steps.
