1. A display apparatus comprising:
a first display portion where first pixels are arranged in a matrix;
a second display portion where second pixels are arranged in a matrix;
a first row driver circuit;
a second row driver circuit; and
a control circuit,
wherein each of the first pixels and the second pixels comprises a light-receiving element,
wherein each of the first pixels and the second pixels is configured to acquire imaging data using the light-receiving element,
wherein the first row driver circuit is configured to select one of the first pixels from which the imaging data is to be read out,
wherein the second row driver circuit is configured to select one of the second pixels from which the imaging data is to be read out,
wherein the control circuit is configured to perform driving in a first mode in which the first row driver circuit and the second row driver circuit are sequentially driven,
wherein the control circuit is configured to perform driving in a second mode in which one of the first row driver circuit and the second row driver circuit is driven based on a basis of the imaging data, and
wherein each of scan rates of the first row driver circuit and the second row driver circuit in the first mode is higher than a scan rate of the first row driver circuit or the second row driver circuit in the second mode.
