1. An image sensing device comprising:
a plurality of pixels;
a receiver configured to perform signal reception from a sensor which is different from the image sensing device; and
a control circuit configured to generate (1) a first signal which gives a first timing based on one of (a) a leading edge of a signal received by the receiver from the sensor and (b) a trailing edge of a signal received by the receiver from the sensor and (2) a second signal which gives a second timing based on the other of the leading edge and the trailing edge,
wherein each of the plurality of pixels includes a photoelectric converter, a first charge holding portion configured to hold charges generated by the photoelectric converter, and a second charge holding portion configured to hold charges generated by the photoelectric converter, and
wherein in each of the plurality of pixels, the charges whose accumulation is started in the photoelectric converter in accordance with the first signal are held by the first charge holding portion, and the charges whose accumulation is started in the photoelectric converter in accordance with the second signal are held by the second charge holding portion.
