Abstract: An electronic still camera having an image pickup device for converting the image of an object into an image signal; a regulator for regulating the amount of exposure of the image pickup device; a controller for causing the image pickup device to generate the image signal plural times and controlling the regulator in such a manner that the plural image signals have mutually different amounts of exposure; a mean calculator for calculating the mean value of data of mutually corresponding pixels in the plural image signals; and a recording device for recording a mean image signal thus obtained.

Abstract: An electronic still camera for recording stationary images comprises a light metering device for light-metering a plurality of portions of an object to be photographed and outputting a pluraltiy of signals corresponding to the quantities of light of the portions, an image pickup device for converting the image of the object to be photographed into an image signal, a contour enhancing device provided with a plurality of selectable contour enhancement degrees and enhancing the contour of the image signal, and a selecting device for effecting calculation on the basis of the outputs from the light metering device and selecting one of the plurality of contour enhancement degrees provided in the contour enhancing device on the basis of the result of the calculation.

Abstract: An electric still camera is provided with a device for varying the gain of an image signal amplifying circuit in response to the excess or deficiency of the amount of light from a flash unit, before the image signal is recorded.
