Abstract
An electronic camera of the present invention includes a CCD, a diaphragm, an EEPROM, and a CPU. The CCD has a condenser micro-lens opposed to a light receptor. The diameter of the diaphragm is variable in relation to a plurality of f-numbers. In the EEPROM, data items of outputs of the CCD associated with the plurality of f-numbers or ratios of the outputs are stored in advance. The CPU calculates an exposure time according to an output of the CCD associated with a given f-number, controls exposure, and corrects an exposure time according to data stored in the EEPROM during recording.
