Abstract
An electronic camera for producing a composite image having a wide dynamic range and a high quality by composing first and second image signals obtained by picking-up an object successively two times with first and second stroboscopic flash exposures having a predetermined exposure amount ratio, including a CCD image sensing element, a stroboscopic flash device, and a flash light control circuit for controlling an excited emission of said stroboscopic flash device. At an end of the first exposure, the excited light emission from the stroboscopic flash device is temporarily stopped, but an excited condition of the stroboscopic flash device is kept. During this very short light emission interruption period, electrostatic charges stored in a light receiving section of the CCD image sensing element during the first exposure are transferred into a vertical transfer section. After that, the excited flash light is emitted again to perform the second exposure without recharging a trigger capacitance.
