Abstract
An image sensing apparatus is provided with an aperture unit (104), an image sensor (106) that converts light beams entering through a photographing lens (103) and the aperture unit into electrical signals, and a display unit (107), including an electronic viewfinder mode to continuously display on the display unit images based on the electrical signals obtained by the image sensor. The image sensing apparatus has a control unit (135) that causes the aperture unit to stop down, when there is an instruction to display on the display unit an image other than the image based on the electrical signals obtained by the image sensor while in the electronic viewfinder mode.
Claims7
An image sensing apparatus having:
- an aperture unit;
- an image sensor adapted to convert light entering through a photographing lens and the aperture unit into electrical signals;
- and
- a display unit,
- the image sensing apparatus having an electronic viewfinder mode in which an image based on electrical signals obtained by the image sensor is displayed continuously on the display unit, wherein the image sensing apparatus further comprises:
- a control unit operable to cause the aperture unit to stop down if there is an instruction to display an image other than an image based on electrical signals obtained by the image sensor on the display unit while in the electronic viewfinder mode.
A control method for an image sensing apparatus that includes an aperture unit, an image sensor that converts light entering through a photographing lens and the aperture unit into electrical signals, and a display unit, and that is operable in an electronic viewfinder mode in which an image based on electrical signals obtained by the image sensor is displayed continuously on the display unit, the control method being comprising:
- stopping down the aperture unit if there is an instruction to display on the display unit an image other than an image based on electrical signals obtained by the image sensor while in the electronic viewfinder mode.
