Abstract
The invention is a display device and method for correcting the amount of emitted light and brightness level from multiple light sources, which illuminate an object that is being imaged and displayed by a display module. The device and system include multiple temperature sensors that correspond to each of the multiple positions in the display module. The device and system also include a computer processor, which operates as a correction unit to individually correct the brightness for each of the multiple light sources based on the detected temperatures, detected by the temperature sensors, respectively, and the dispersion of the plurality of temperatures. The correction unit also performs (1) the temperature correction processing, to individually correct each of the multiple measured temperatures based on the dispersion; and (2) the brightness correction processing, to individually correct each of the brightness levels of the multiple light sources based on the corrected temperatures.
