An imaging and pulse detection pixel and an array of imaging and pulse detection pixels are provided. Each imaging and pulse detection pixel includes an optical detection device connected directly to a first and second transistor only, a pulse detection circuit that operates on the signal read out from the optical detection device and outputs a pulse detection output signal suitable for detection of pulses, and an imaging circuit that operates on a signal read out from the optical detection device and outputs an image output signal suitable for generation of an image. A terminal of the optical detection device is directly connected to only a gate terminal of the first transistor and a non-gate terminal of the second transistor.
