Abstract
A method for controlling a pixel including at least one photodiode capable of being connected to a sense node, the method including the steps of: a) at the beginning and at the end of a first integration period included within a second integration period, controlling the pixel to transfer the charges stored in the photodiode above a first threshold onto the sense node; and b) at an intermediate time between the beginning of the second period and the beginning of the first period, controlling the pixel to transfer the charges stored in the photodiode above the first threshold onto the sense node.
