A camera apparatus includes a single release switch member. The single release switch member is for instructing an image capture operation, and selects one of a first operative state and a second operative state. The first operative state is selected when the single release switch member is pushed down to a first depth. The second operative state is selected when the single release switch member is pushed down to a second depth which is deeper than the first depth. The camera apparatus selects a recordable portion of a recording medium in response to selection of the first operative state, and generates a predetermined electrical signal if the camera apparatus selects the recordable portion of the recording medium. The camera apparatus records the image signal on the selected recordable portion if the second operative state is selected by the single release switch member, and the predetermined electrical signal is generated.
