  • Patent number: 8830371
    Abstract: An image pickup apparatus capable of reducing the influence of dark current noise to thereby obtain excellent image quality, even when the dynamic range is expanded under a photographing condition. In an image pickup element of a CMOS image sensor of the apparatus, a photo diode (PD) generates and accumulates electric charge according to an optical input, and a floating diffusion portion (FD) accumulates the electric charges. A charge holding portion (MEM) is disposed between PD and FD. A first transfer transistor selectively separates and connect between PD and MEM, and a second transfer transistor selectively separates and connects between MEM and FD. A system control circuit sets an operation mode to either a first operation mode in which PD and MEM are separated or a second operation mode according to photographing conditions for shooting an object in which PD and MEM are connected.
