LED ILLUMINATION CALIBRATION APPARATUS AND CONTROL METHOD THEREOF

摘要

Disclosed is an LED brightness calibration apparatus which can improve LED quality uniformity by quickly calibrating the brightness of a plurality of LEDs. The LED brightness calibration apparatus comprises: a storage unit for storing brightness information of a reference image photographing reference LED brightness; and a processor for controlling current supply of a target LED to match a brightness value on at least one area of the reference image with a brightness value of an area corresponding to the at least one area of the reference image among images photographing brightness of the target LED based on the information stored in the storage unit.
