Pixels output a first signal based on signal charge of a part of photoelectric conversion units of multiple photoelectric conversion units, and a second signal based on signal charge of multiple photoelectric conversion units. An imaging apparatus outputs signals based on the first signals and signals based on the second signals by reducing the number of signals based on the first signals as compared to the number of signals based on the second signals.

Imaging apparatus, and imaging system having a plurality of pixels for outputting a signal based on a generated signal charge

An actuator includes a control part, a first rotation sensor, and a second rotation sensor able to detect rotation of an output shaft. The control part performs a first rotation angle acquisition control for acquiring a target rotation angle of the output shaft when a movable part is moved from the second position to the first position as a first rotation angle. The first rotation angle is a rotation angle of the output shaft that is closer to the second position side than when the movable part abuts the first wall part. In the first rotation angle acquisition control, the control part causes the movable part abuts the first wall part, acquires a rotation angle of the output shaft when the movable part has abutted the first wall part, and calculates the first rotation angle based on the rotation angle of the output shaft that has been acquired.
