Abstract:
A brightness adjusting device of the present invention includes: a brightness setting section that accepts input of brightness change information that is an instruction to change a brightness setting value; a brightness adjusting section that performs brightness adjustment by either one of a first brightness adjusting unit and a second brightness adjusting unit having different characteristics from each other, in accordance with the instruction that is input from the brightness setting section; a determining section that determines whether or not the brightness adjustment of the brightness adjusting section switches from the first brightness adjusting unit to the second brightness adjusting unit; and an output section that outputs an alarm when the brightness adjustment of the brightness adjusting section is determined to switch from the first brightness adjusting unit to the second brightness adjusting unit based on a determination result of the determining section.
