ABSTRACT:
A image-sensing device includes an array of light-sensing pixels arranged in rows, a readout circuit, and a control logic coupled to the rows of pixels. Each of the pixels has a respective conversion gain that changes to a respective second value from a respective first value within a settling time when a control signal is applied to the pixel. The readout circuit is coupled to the array of pixels and samples the rows of pixels once in an array sampling process. The control logic applies the control signal to the pixels of at least one row after sampling of the pixels in at least one other row of the array has begun but at least the settling time before the at least one row is sampled.
