Image display device, brightness control method and brightness control program
View Patent ↗An image display device includes a display unit that is installed inside a finder window provided in a housing and displays images, an obtaining unit that obtains brightness of a space inside the finder window, and a control unit that when the brightness obtained by the obtaining unit is a first brightness, sets the brightness of the display unit to a second brightness, and when the brightness obtained by the obtaining unit is a third brightness brighter than the first brightness, sets the brightness of the display unit to a fourth brightness brighter than the second brightness.
1. An image display device comprising:
a display unit that is installed inside a finder window provided in a housing and displays images;
an obtaining unit that obtains brightness of a space inside the finder window; and
a control unit that when the brightness obtained by the obtaining unit is a first brightness, sets the brightness of the display unit to a second brightness, and when the brightness obtained by the obtaining unit is a third brightness brighter than the first brightness, sets the brightness of the display unit to a fourth brightness brighter than the second brightness.
2. The image display device according to claim 1 , wherein at least wall surfaces around the display unit of wall surfaces inside the housing are white.
3. A brightness control method comprising:
displaying images on a display unit installed inside a finder window provided in a housing;
obtaining brightness of a space inside the finder window; and
when the obtained brightness is first brightness, setting the brightness of the display unit to a second brightness, and when the obtained brightness is a third brightness brighter than the first brightness, setting the brightness of the display unit to a fourth brightness brighter than the second brightness.
4. A non-transitory computer-readable medium, storing thereon a brightness control program enabling a computer to perform:
displaying images on a display unit installed inside a finder window provided in a housing;
obtaining brightness of a space inside the finder window; and
when the obtained brightness is a first brightness, setting the brightness of the display unit to a second brightness, and when the obtained brightness is a third brightness brighter than the first brightness, setting the brightness of the display unit to fourth brightness brighter than the second brightness.
5. The image display device according to claim 1 , further comprising an illumination unit disposed inside the finder window, wherein the brightness obtained by the obtaining unit is at least partly dependent on an amount of illumination output by the illumination unit.
