Abstract
An endoscope apparatus includes: a light-emitting element; a rolling shutter-type image pickup device allowing an exposure period in which the plurality of lines are simultaneously exposed and a reading period in which image pickup signals of the respective lines are sequentially read to be alternately switched to each other; and a control section. The control section controls an intensity of the light emitted by the light-emitting element. The control section can perform switching between a first illumination mode in which the light is applied from the light-emitting element in the exposure period and the reading period and a second illumination mode in which the light is applied from the light-emitting element only in the exposure period, and if the intensity of the light is controlled so as to have a predetermined value, performs control to switch one of the first mode and the second mode to the other.
