Abstract
Provided are a light intensity detection circuit, a light intensity detection method and an light intensity detection apparatus. The light intensity detection circuit includes a photoelectric conversion sub-circuit, a source follower sub-circuit, a reset sub-circuit, a read sub-circuit and a sense sub-circuit. The photoelectric conversion sub-circuit generates a corresponding electrical signal according to an incident light signal, and outputs it to a first node; the source follower sub-circuit generates a corresponding voltage signal or current signal according to the electrical signal of the first node and outputs it to a second node; the read sub-circuit reads the voltage signal or current signal of the second node to determine an incident light intensity; the reset sub-circuit provides a voltage at a offset voltage terminal to the first node.
