Abstract
An image pickup apparatus is capable of reducing saturation of a photoelectric conversion part at a time of photometry. The image pickup apparatus includes a photographing lens and an image pickup device including the following units. A photoelectric conversion part generates an electric charge by converting incident light through the lens photoelectrically and can accumulate the generated electric charge. A transfer switch transfers the electric charge to a charge accumulation part from the photoelectric conversion part. A control unit selectively sets a driving mode from among a first driving mode in which the electric charge generated by the photoelectric conversion part is intermittently transferred to the charge accumulation part by switching ON/OFF of the transfer switch and a second driving mode in which the electric charge generated by the photoelectric conversion part is continuously transferred to the charge accumulation part by keeping an ON state of the transfer switch.
