Solid state sensor having logarithmic photovoltaic response, with pixel uniformity correction and white balance circuitry therefor |
摘要 |
A solid-state image sensing apparatus includes a solid state image sensing device having a characteristic that an output voltage thereof natural-logarithmically varies in accordance with light reception amount. An image sensing output signal is obtained with respect to each pixel when uniform light is irradiated to the solid-state image sensing device. The difference is then calculated between an image sensing output signal obtained with respect to each pixel in actual sensing and an image sensing output signal with respect to a pixel corresponding thereto which signal is stored, to form an image signal.
