ABSTRACT:
A still video adapter device is detachably mounted to a back portion of a camera body, in place of a rear cover. The light passing through an objective lens of the camera body is relayed by a relay optical system and split into two groups, one being directed to an image sensor for the still video photography, the other to a light measuring element for the exposure control. The output of the light measuring element is integrated and compared with a given value, thereby generating a signal for interrupting the flash light emission when the integrated value reaches the given value.
