Abstract
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.
