摘要： Imaging apparatus (100, 200, 1200) includes a semiconductor substrate (312) and an array (202) of pixel circuits (1202, 1204), which are arranged in a matrix on the semiconductor substrate and define respective pixels (212) of the apparatus. Pixel electrodes (1208) are respectively coupled to the pixel circuits, and a photosensitive (1206) is formed over the pixel electrodes. A common electrode (1207), which is at least partially transparent, is formed over the photosensitive film. An opaque metallization layer (1214) is formed over the photosensitive film on one or more of the pixels and coupled in ohmic contact to the common electrode. Control circuitry (208, 1212) is coupled to apply a bias to the common electrode via the opaque metallization layer while correcting a black level of the output values from the pixels using the signals received from the one or more of the pixels over which the opaque metallization layer is formed.

摘要： Various embodiments comprise apparatuses and methods including a light sensor. In one embodiment, an integrated circuit includes an image sensing array region, a first photosensor having a light-sensitive region outside of the image sensing array region, and control circuitry. The control circuitry is arranged in a first mode to read out image data from the image sensing array region, where the data provide information indicative of an image incident on the image sensing array region of the integrated circuit. The control circuitry is arranged in a second mode to read out a signal from the first photosensor indicative of intensity of light incident on the light-sensitive region of the first photosensor. Electrical power consumed by the integrated circuit during the second mode is at least ten times lower than electrical power consumed by the integrated circuit during the first mode. Additional methods and apparatuses are described.
