Abstract
The image sensing device adapted to compose an appropriate single picture from a plurality of pictures of different exposures obtained from the same subject, wherein the camera operation is controlled using as a reference the signal of one of said plurality of pictures of different exposures.
Claims7
An image sensing apparatus comprising:
- (a) image sensing means for sensing an image;
- (b) image composing means for composing an image with a plurality of image signals output from said image sensing means;
- (c) comparison means for comparing a luminance signal level of said plurality of image signals with a predetermined reference level, said comparison means evaluating the luminance signal level distribution;
- (d) controlling means for controlling a composing condition based on a comparison result of said comparison means.
