Abstract

PURPOSE: To perform correct dimming operation regardless of the position and the state of a subject by providing a dimming means which divides a photographic area into plural areas and dims light, and dimming the light of an area where the subject is present.
CONSTITUTION: When a command signal is outputted from a command signal generating means 2 to a storage means 3, the storage means 3 stores a light metering output corresponding to the brightness of the center part of an image plane among divided areas whose light is metered by a division light metering means 1. A selecting means 4 inputs the light metering output of the image plane center part light metering outputs of the respective divided areas to detect the correlation among them. Then, the position of the subject is detected and an area to be dimmed is specified to the dimming means 5 which dims plural areas.
