Abstract: An electronic device includes a connection unit, a communication unit configured to communicate with a first external device or a second external device, and a control unit configured to control the electronic device. The control unit controls the electronic device so that at least one terminal of the connection unit is connected to the communication unit in a case where the first external device is connected to the connection unit. The control unit controls the electronic device so that at least one terminal of the connection unit is connected to the control unit in a case where the second external device is connected to the connection unit.

Abstract: An image sensor, comprising pixels that have paired first pixel sections and second pixel sections, and a pixel signal generation circuit that repeatedly outputs an pixel signal, wherein the pixel signal generation circuit in a first frame among image frames, adds pixel signals of the first pixel sections corresponding to a first column to generate a first pixel addition signal, adds pixel signals of the second pixel sections corresponding to a second column to generate a second pixel addition signal, and respectively outputs the first and second pixel addition signals, and in a second frame that is continuous to the first frame, adds outputs of the second pixel section corresponding to the first column to generate a third pixel addition signal, adds outputs of the first pixel section corresponding to the second column to generate a fourth pixel addition signal, and respectively outputs the third and fourth pixel addition signals.
