摘要:
A display device in the finder of a camera has a plurality of digits of light-emitting elements for displaying exposure information on the side of a frame of field of view of the finder. The light-emitting element of the nearest one of the digits to the frame of field of view is made brightest, and, as the distance from the frame increases, the brightness of the light-emitting element of each digit is made lower. Therefore, the apparent brightnesses of all the light-emitting elements become almost equal to one another, permitting the observer to read the displayed information with ease and clearness.
