Abstract
An electronic apparatus having a photographing function includes: a flash that emits light including a visible light wavelength range and an infrared wavelength range and radiates the light onto a subject; an infrared detector that absorbs light in the infrared wavelength range and generates a detection signal corresponding to the light; an image sensor that photoelectrically transforms incident light and generates an image signal; and a controller that controls an exposure time of the image sensor based on the detection signal.
