摘要： A sensor pixel circuit (9) includes: a light receiving element (PD); a first node Vsig that retains charges corresponding to an amount of light incident on the light receiving element; and a second node Vint that receives charges from the first nodeVsig and retains the charges. Under control by a driving circuit (7), during one of a detection period while a light source (3) for sensors is in an ON state and a detection period while the light source (3) for sensors is in an OFF state, charges corresponding to an amount of light incident on the light receiving element (PD) during this detection period are accumulated in the first node Vsig. The charges accumulated are transferred from the first node Vsig to the second node Vint. During the other one of the detection period while the light source for sensors is in the ON state and the detection period while the light source for sensors is in the OFF state, charges corresponding to an amount of light incident on the light receiving element (PD) during this detection period are accumulated in the first node Vsig, and the charges accumulated are transferred from the first node Vsig to the second node Vint. By doing so, a value of a difference between the amount of light accumulated while the light source for sensors is in the ON state and the amount of light accumulated while the light source for sensors is in the OFF state is determined in the second node Vint.
