Abstract
An electronic camera is disclosed, which comprises a CCD image pick-up device , a CCD driver for setting the photoelectric charge accumulation time of the CCD image pick-up device, an image pick-up circuit including gain control means, for processing a signal from the CCD image pick-up device to obtain an image signal, and CPU for sequentially executing an AE, an AF and an AWB process according to an AE, an AF and an AWB evaluation values obtained by using the image signal. The gain of the image signal is updated by adding ⅓ of the change in a gain setting value obtained in the AE process executed by the CPU for each frame. The image brightness is thus varied smoothly to provide movie images not giving any sense of uncomfortability.
