摘要： A solid state imager converts analog pixel values to digital form on an arrayed per-column basis. A counter is coupled to an N-bit DAC to produce an analog ramp that varies corresponding to the contents of the counter. A ripple counter is associated with each respective column. A clock or a source of counts at a predetermined sequence supplies clock signals or counts to the counter elements. Column comparators gate the counter elements when the analog ramp equals the pixel value. The counter contents feed a video output bus to produce the digital video signal. Additional black-level readout counters elements can create and store a black level digital value that is subtracted from the pixel value to reduce fixed pattern noise. The counters may employ two's complement arithmetic. An additional array of buffer counter/latches can be employed. Ripple counters can be configured as counters to capture the digital video level, and then as shift registers to clock out the video levels to an output bus. The clock pulses or counts for the DAC counter and for the ripple counters can be at the same or different rates.

SOLUTION: An illumination intensity level mapping controller determines a number of pixels of image data having illumination intensity levels within a first defined range of illumination intensity levels and determines an illumination intensity level mapping function based upon the determined number of pixels within the first defined range of illumination intensity levels. An exposure controller determines a number of pixels having illumination intensity levels within a second defined range of illumination intensity levels and determines an integration time based upon the determined number of pixels having illumination intensity levels within the second defined range of illumination intensity levels. A transfer control function generation circuit determines a composite transfer control function based on determined integration time and the determined illumination intensity level mapping function; determines each transition point between a plurality of discrete transfer control functions from the determined integration time and the determined illumination intensity level mapping function; and imposes the determined transfer control function upon a pixel of the digital imager.
