Abstract

The present invention pertains to a pixel for use in a system for determining a distance to an object by range gating, said pixel comprising: a first charge storage well (221) and a second charge storage well (222) for accumulating electrical charges representative of amounts of light impinging on said pixel during respective sets of exposure intervals, wherein said first charge storage well (221) has a charge capacity that is at least 50% greater than a charge capacity of said second charge storage well (222). The invention also pertains to a range gating system comprising such a pixel.
