Belichtungskontrolle mit fester Belichtungszeit bei hohem Leuchtniveau.

摘要

A camera having an automatic exposure system for providing decreasing aperture-interval values with increasing ambient light levels including an ambient light level sensor element for detecting an ambient light level equal to a predetermined high ambient light level and a control system for overriding the automatic exposure system in response to detection of said predetermined level for providing a fixed effective aperture and fixed exposure time interval corresponding to the aperture-interval value defined by the automatic exposure system at the predetermined level whereby increased exposure is provided at light levels greater than the predetermined level to thereby provide a scene overexposure increasing with the amount of ambient light exceeding the predetermined level so as to provide acceptable exposure of a subject within that high light level scene.
