Abstract

If an electronic camera is set in an image-capturing sensitivity automatic control mode, a program autoexposure calculation is executed based upon the subject brightness and the image-capturing sensitivity setting to determine a control aperture value and a control shutter speed. If the correct exposure is not achieved, a control exposure sensitivity is calculated based upon the exposure deviation and the image-capturing sensitivity setting is adjusted accordingly. If an internal flash unit or an external flash unit is utilized, an autoexposure calculation is executed by using the flash unit synchronizing speed, the subject brightness and the image-capturing sensitivity setting to determine the control aperture value.
