US Patent 7580056 Digital still camera

It is aimed to provide a small and lightweight digital still camera capable of reducing the possibility of moving the digital still camera while an image is taken due to an operation for pressing a shutter switch by a user. Thus, a single-stage switch which is turned on when the user presses up to a predetermined stroke with his/her finger and is turned off when the user takes his/her finger off is used as the shutter switch. In the normal imaging mode, in a state where the shutter switch is turned on by the user, an image for monitoring is taken at a predetermined interval and the image is displayed on the display device as an electronic view finder using image data output from the imaging device. When the shutter switch is turned off, an image for recording is taken, the obtained image data is recorded in the memory card and the taken image is displayed on the display device using the image data.
