Abstract
The present invention discloses a finder device capable of adjusting the amount of light emitted from a light-emitting display section arranged in the device according to the light-receiving level of an image pickup device. The amount of light emitted is adjusted, for example, so that the light-receiving level of the image pickup device is not saturated. The light-emitting display section can be configured, for example, to include a LED display element for projecting light onto a mat screen in the finder device and a drive circuit that can adjust the amount of LED light, or to include an LCD display unit provided adjacent to the mat screen and a backlight unit that can adjust the amount of light for the LCD unit.
