Smart pixels in a focal-plane image compression system

Image compressors improve the handling of image data in image-processing systems. In our proposed image-compression system, we employ a smart complementary metal oxide semiconductor (CMOS) sensor and an integrated spatial light modulator (SLM) and then the optoelectronic architecture performs a large part of image-compression processes. Each pixel of the integrated SLM consists of multiple modulation pads; the integrated SLM then performs decoding and optical D/A conversion. A paired configuration of the smart CMOS sensor and the integrated SLM transforms optical analog signals into electronic digital signals. A theoretical analysis showed that the error ratio of the proposed systems was 3%.
