とした電子スチルカメラ。 An optical system that includes an automatic focusing mechanism that automatically focuses the photographic lens based on the output signal of the distance measuring means that measures the distance to the subject, and the image of the subject is displayed on the monitor based on the output signal from the image sensor. In an electronic still camera equipped with an electronic viewfinder section, the photographing lens is configured with a zoom lens, and zooms when the amount of skin color signal component in the video signal obtained from the output signal is less than a predetermined reference skin color signal. An electronic still camera characterized by having a control means for driving a lens mechanism to zoom up.
