    Abstract: An image device has an array of pixels, each pixel having a photosensitive area, a first storage node and a second storage node. A pixel is illuminated for a first period of time, and charge accumulated on the photosensitive area of the pixel during the first period of time is stored on the first storage node of the pixel. The pixel of the array is illuminated for a second period of time, and charge accumulated on the photosensitive area during the second period of time is stored on the second storage node of the pixel. A first signal is generated based on the charge stored on the first storage node, and a second signal is generated based on the charge stored on the second storage node. The first and second signals are combined using at least one subtraction operation having the first and second signals as operands.

    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.
