Abstract:
An electronic camera which enables imaging a moving picture and a still picture, comprising:a diaphragm which intercepts partially or wholly incident light, said diaphragm being closed when imaging said still picture;an image sensor device which converts said incident light focused thereon into an electric signal;an image sensor driving circuit which drives said image sensor device;a signal processing circuit which processes the electric signal outputted from said image sensor device; anda control circuit which controls said diaphragm and said image sensor driving circuit according to an amount of exposure determined based on a luminance signal outputted from said signal processing circuit;wherein said control circuit determines an amount of exposure for imaging said still picture based on an amount of exposure determined during imaging said moving picture, and controls said diaphragm to close from a last aperture of imaging said moving picture.
