Method of controlling integration time using IR, Computer readable storage medium of recording the method and a digital photographing apparatus

摘要

The present invention discloses a digital photographing apparatus, comprising a flash for emitting light having a visible wavelength range and an infrared wavelength range to illuminate a subject; an infrared detection unit for absorbing light having an infrared wavelength range to generate a detection signal corresponding to the light; an image sensor for photoelectrically converting incident light to generate an image signal; and a control unit for controlling an exposure time of the image sensor based on the detection signal.
