A matching adjustment between left and right screens is easily and accurately performed in a digital stereo camera and/or a digital stereo video camera at or after the time of photographing. A stereo viewfinder 3 of a digital stereo camera 1 comprises a pair of left and right liquid crystal displays and eyepiece lenses 10. Aspect ratios of left and right image display regions of the liquid crystal displays is made narrower than aspect ratios of image capture regions of image capture devices and horizontal scrolling is performed symmetrically. Images on the image capture devices are horizontally scrolled, while finder images are viewed in a stereoscopic manner with both eyes, so that perspective of a stereoscopic image changes and an optimally scrolled image data can be photographed. Scroll adjustment can be performed on image data after being photographed, and stereo photographs giving an optimal stereoscopic feeling can be printed from edited image data.
