摘要: An imaging system capable of black level calibration includes an pixel array, at least one reference pixel, and peripheral circuitry. The array a plurality active pixels each coupled to capture image data. is generate signal for calibrating the Light transmitting layers are disposed on first side die including cover pixel. A light shielding layer covers portion without covering array.
