Abstract
An electronic still camera includes a finder optical system for viewing a subject image. An imaging section obtains the subject image. A display section displays the subject image based on image data associated with the subject image obtained by the imaging section. A mode selecting section selects either a first mode in which the electronic still camera performs imaging operation using the imaging section while a user views the subject image through the finder optical system or a second mode in which the electronic still camera performs imaging operation using the imaging section while the user views the subject image on the display section. A first focus detection circuit performs a first focus detecting operation when the first mode is selected by the mode selecting section. A second focus detection circuit performs a second focus detecting operation when the second mode is selected by the mode selecting section.
