Abstract:
An electronic camera producing an image having a wide dynamic range by composing two image signals obtained by picking-up an object two times successively with different exposure amounts, comprising:an image picking-up means including a solid state image sensing element for picking-up an object to derive an image signal; a flash light emitting means for irradiating said object with flash light; an image signal composing means for composing two image signals obtained by picking-up the object two times with a desired exposure amount ratio; and a flash light emission controlling means for controlling an excited emission of said flash light emitting means in accordance with said desired exposure amount ratio such that upon the first exposure, said flash light emitting means is excited and the flash light is emitted, an excited condition of the flash light emitting means is kept over said second exposure, and after once stopping the light emission at an end of the first exposure, the flash light is emitted again to perform the second exposure.
