Method and apparatus for transversely staged combustion utilizing forced internal recirculation

A method for generating an outpnt signal corresponding to an image focused on a sensor array having rows and columns of pixel sensors on a substrate wherein two adjacent pixel sensors in a row are connected to a shared column line, each sensor capable of collecting electrical charge based on a detected light intensity, the method comprising the steps of:

• activating a first sensor in a row connected to a shared column line for a first period of time then subsequently activating an adjacent second sensor in the row connected to said shared column line for a second period of time;
• detecting a first voltage at a node of a respective activated sensor;
• resetting the voltage of the respective nodes of said activated sensors to a predetermined voltage, wherein said voltage is reset by a reset transistor addressed by a reset line which is linear in said substrate;
• transferring electrical charges collected by said activated sensor to said node;
• generating an output signal over said shared column line.
