MOBILE TERMINAL HAVING CAMERA FLASH AND METHOD FOR CONTROLLING CAMERA FLASH
Abstract:
A mobile terminal including an LED camera flash includes a lens, which is for photographing an object, an image sensing unit, which generates a sensor result value by executing automatic exposure and automatic white balance, a flash module, which includes a flash driving unit that controls the LED camera flash, an actuator, which moves the lens and records a distance traveled by the lens, and a camera control module, which sets an exposure gain value by using the sensor result value, extracts a distance current value and a distance gain value by using position information of the lens that is determined by using the distance traveled by the lens, and controls the flash driving unit so as to adjust a brightness of the LED camera flash according to a gain correction value, which is set by using the exposure gain value, the distance current value and the distance gain value.
