Claims
- 1. A built-in flash camera including a strobe light therein, the built-in flash camera comprising:
- a photometry part for measuring a brightness within a shot visual field;
- a focusing part for measuring a distance between a camera and an object within the shot visual field;
- an automatic exposure mechanism for opening and closing a combination shutter and a stop blade so as to obtain a predetermined exposure in response to the measured brightness of external light being more than a predetermined reference external light brightness, the predetermined reference external light brightness being an external light brightness at which an optimum exposure is obtained when a shutter is opened for a predetermined time; and
- a strobe light control part for directing the strobe to flash every time in connection with the opening and closing of the shutter and for decreasing the exposure of the strobe in accordance with the measured brightness and the measured distance, the strobe light control part prohibiting the strobe from flashing when the measured brightness is above a predetermined brightness and the measured distance is above a predetermined distance.
- 2. A built-in flash camera as set forth in claim 1, wherein a correction table including a plurality of brightnesses, distances and corresponding aperture correction values is stored in the built-in flash camera, and wherein the strobe flashing is prohibited in accordance with an aperture values, corrected in accordance with the correction table, the aperture value being required for determining flash timing.
- 3. The built-in flash camera as set forth in claim 2, wherein, in the correction table, distance between the camera and the object is classified into a plurality of levels and the external light brightness within the shot visual field is classified into a plurality of levels, and a correction value for adjusting the exposure of the strobe is stored for each level.
- 4. A built-in flash camera as set forth in claim 1, wherein the built-in flash camera calculates an exposure value and an aperture value based upon the measured brightness and the measured distance, wherein the strobe flashing is prohibited in accordance with the calculated aperture value and the calculated exposure value.
- 5. The built-in flash camera of claim 2, wherein the correction table includes a plurality of values for decreasing the aperture value by predetermined incremental percentages.
- 6. The built-in flash camera of claim 1 wherein, for measured distances above a predetermined distance, the amount of the strobe is either reduced to 0 or maintained at 100%.
