ABSTRACT:
An electronic image pickup apparatus comprising a focal plane shutter for controlling reception or cut-off of the light from an object, a CMD, image pickup device as a MOS-type internal amplification sensor, RGB channel process circuits for processing RGB outputs from the CMD, and a system controller for controlling the entire apparatus. The focal plane shutter lets in the light from the object to photograph for exposure. The resulting image data is temporarily stored in a memory. With no light from the object projected onto the CMD, a dark exposure is performed for the same time as the exposure to extract a signal corresponding to dark current. Reading the image data from the memory and reading the data at the dark exposure are performed at the same time. The dark current component is removed by subtracting the dark exposure data from the image data.
