Abstract

A brightness adjustment method provides a brightness adjustment interface for allowing a user to operate the input unit to adjust the brightness of any area in the image in the brightness adjustment interface. When the user operates the input unit to adjust the brightness of any area in the image in the brightness adjustment interface, the processing unit of the image capturing device responds to the operation of the input unit to adjust the light-emitting intensity of the light-emitting unit accordingly. When the illumination intensity of the illumination unit changes, the brightness of the corresponding area in the image also changes. Thereby, the user can easily adjust the illumination intensity of any of the illumination units through the brightness adjustment interface to adjust the brightness of the corresponding area in the image.
