Abstract: An electronic flash device and a camera which can smoothly display a video even though preliminary emission for red-eye reduction in photographing the video are obtained. A timing generator generates a preliminary emission signal such that preliminary emission for red-eye reduction by a light emitting tube is performed in a period of operation of an electronic shutter arranged in an interline CCD to input the preliminary emission signal to a trigger circuit. The timing generator sets a period in which the preliminary emission signal is set at an active level as a period corresponding to a cycle between the edge of a pulse of a transfer gate signal serving as for transferring signal charges from a light-receiving element of the CCD to a vertical transfer path and the edge of a pulse of an overflow drain signal representing a timing at which excess charges are drained by an overflow drain of the CCD.

Abstract: The present invention relates to an electronic flash device capable of dimming control, particularly with the objective of enhancing the dimming precision in weak light emissions. The electronic flash device of the present invention thus predicts the quantity of overrun light after stopping of the emission based on the target quantity of emission, and performs correction to advance emission stop timing in accordance with the quantity of overrun light. Here, the rate between the target quantity of emission and the quantity of full emission by the emission means (the rate of emission) is preferably obtained so that the quantity of overrun light after stopping of the emission is predicted based on the rate of emission. In split emission, the emission stop timing is preferably corrected on each chopper emission.

Abstract: A lens-fitted photo film unit is provided with a stop blade that is switched over between a small aperture position and a large aperture position depending upon a subject brightness measured through a photometric circuit that is activated when a shutter button is pressed. The film unit has an f-number of not more than f/8.0 when the stop blade is in the large aperture position, or an f-number of not less than f/14 when the stop blade is in the small aperture position. The film unit is also provided with a flash light control circuit in connection to a flash device. The flash light control circuit measures a light amount reflected from a subject while a flash light is projected from the flash device toward the subject, to stop the flash device from projecting the flash light when the measured light amount reaches a predetermined value.

Abstract: A power source part supplies power to an electronic flash charging circuit and camera circuits such as an LCD backlight circuit. When the charge begins, the electricity stops being supplied to the camera circuits, and a high current (first charging current) is sent to the electronic flash charging circuit so that the electronic flash is rapidly charged. When the charging voltage of the electronic flash reaches a light-emission-possible voltage that is lower than a full-charge voltage, the charging current is lowered and the charge is continued, and the camera circuits such as the LCD backlight circuit and an imaging circuit start to be activated at the same time. Thus, a decline of the performance of the electronic flash such as a decline of the guide number and a reduction of the light-emission-possible time can be prevented, and the preparation time from the start of the charge to the time at which the camera gets ready for the shooting can be shortened.
