发明名称 Image sensing apparatus executing exposure control using object luminance information
摘要 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.
