发明名称 Image sensing apparatus
摘要 In an image sensing apparatus having an image sensor which converts an optical image of an object into an electrical signal, a view finder for monitoring the optical image equivalent to the image incident on the image sensor, an optical member arranged in the path of light incident on the image sensor to selectively guide the light to the image sensor and also to the view finder, an exposure member which is at least partially disposed in between the object and the optical member and is arranged to control an exposure and a light receiving element which is arranged separately from the image sensor, a control circuit is arranged to cause the light receiving element to form a first photometric information when the optical member guides the optical image to the view finder; to control the exposure member on the basis of the first photometric information while the optical image is led to the image sensor by the optical member; to cause, after that, the image sensor to form a second photometric information; and again to control the exposure member on the basis of the second photometric information.
