Abstract: A pixel includes a transfer gate, and a sample structure having a first sample stage and a second sample stage. The transfer gate and the first and the second sample stages are configured to be operated in conjunction with a light source in response to a control signal. The first sample stage is configured to sample a first sample value that depends on radiation incident on the photosensitive element from an object or a scene that is illuminated by the light source emitting light at a first output power, while the second sample stage is configured to sample a second sample value that depends on radiation incident on the photosensitive element from the object or the scene that is illuminated by the light source emitting light at a second output power. The first output power is different, in particular significantly different, from the second output power.
