Abstract
A method of acquisition of an image may include accumulating electrical charges by a photosensitive element of a pixel circuit of an image sensor during a first period, transferring the electrical charges accumulated during the first period to a first electrical charge storage region of the pixel circuit, and at the end of the transfer of the electrical charges, accumulating the electrical charges by the photosensitive element during a second period. The method may further include transferring the electrical charges accumulated during the second period to a second electrical charge storage region of the pixel circuit, successively transferring the electrical charges stored in the first and second storage regions to a common reading node of the pixel circuit, acquiring two images from electrical charges transferred to the reading node from the first and second storage regions, respectively, and combining the two images acquired into a resultant image.
