Abstract
A camera may one or more lenses and an image sensor having an array of light-gathering pixels. The pixels may generate image signals based on light passing through the lenses. The camera may include at least one pixel output settling assist circuit. The pixel output settling assist circuit may be electrically coupled to an output signal line of at least one of the pixels. The pixel output settling assist circuit may include a pixel output voltage change detection circuit and a bias current adjustment circuit. During read-out of the image signals of the at least one pixel, the pixel output voltage change detection circuit may detect a change of a voltage at the output of the pixel. The bias current adjustment circuit may generate and adjust a current injected to the output based on the detected change of the voltage at the output.
