Camera using light source having subject eye protection function

Abstract

Provided is a camera using a light source having a subject eye protection function. The camera includes a light source driver installed between a power supply and a light source for emitting light to a subject and configured to convert electric power supplied by the power supply to a pulse current, a light source driver controller configured to control the light source driver to be turned on or off such that the light source driver converts the electric power supplied by the power supply to the pulse current, a current measurement unit configured to measure the pulse current supplied to the light source, an amplitude controller configured to control an amplitude of the pulse current measured by the current measurement unit, a smoothing circuit configured to smooth the pulse current of which the amplitude is controlled by the amplitude controller, and a comparator controller configured to control the electric power supplied by the power supply to be interrupted in a case in which the smooth current smoothed by the smoothing circuit is greater than a preset threshold value.
