METHOD FOR VISUALLY MEASURING BRIGHTNESS OF ILLUMINATION SURROUNDING DISPLAY

摘要

PURPOSE: A method for visually measuring brightness of illumination surrounding a display is provided to measure the brightness of surrounding illumination at a low cost without using an additional device such as a colorimeter or a matching card. CONSTITUTION: Reference brightness is determined based on the kind of a display(S140). A user inputs information about a place where the display is used(S200). Brightness values of predetermined brightness sections are determined based on the reference brightness and the information input by the user. Brightness of predetermined reference image is converted into brightness values corresponding to the brightness sections. Images whose brightness has been converted is displayed to the user(S320). The user inputs information about an image whose brightness is the closest to brightness of illumination surrounding the display to measure the brightness of the surrounding illumination(S340).
