METHOD AND APPARATUS FOR CONTROLLING ANTI-BLOOMING TIMING TO REDUCE EFFECTS OF DARK CURRENT |
摘要 |
An electronic imager includes a plurality of pixels having photosensors for accumulating charge corresponding to individual pixel values of a sensed image. Each of the pixels includes an anti-blooming function which allows charge in excess of a predetermined amount to be drained from the photosensor thus reducing the charge from the pixel that migrates to adjacent pixels. The imager also includes circuitry which controls the anti-blooming function in response to image intensity to reduce dark current in the imager caused by the anti-blooming function.
