Abstract
A method may include a cycle of reading a current pixel including connecting the capacitive node of the pixel to a capacitive node of a previous pixel already read, connecting the capacitive node of the current pixel and the capacitive node of a previous pixel to an output line, reading a first voltage of the capacitive node of the pixel through the output line, transferring charges from the accumulation node to the capacitive node of the pixel, reading a second voltage of the capacitive node of the pixel through the output line, and disconnecting the capacitive node from the capacitive node of a previous pixel, and a cycle of reading a next pixel. This cycle may include accumulating charges in the accumulation node of the next pixel while the capacitive node of the current pixel is connected to a capacitive node of a previous pixel.
