ABSTRACT:
This invention has as its object to provide an apparatus which can match the brightness of an image displayed on a viewfinder with a target luminance level in actual exposure. To achieve this object, the apparatus has an image sensing sensor for converting an optical image into an image signal, a viewfinder for displaying the image signal obtained by the image sensing sensor, and a correction device for correcting the brightness of the viewfinder in accordance with the difference between the luminance level of the image signal obtained by the image sensing sensor, and a target luminance level.
