Abstract: The invention relates to a digital optical instrument including two eyepieces and a folding bridge for adapting the eyepiece distance to the interpupillary distance of the user. In an image recorded by an image sensor, a first bounding frame which is tilted about a first tilt angle relative to the image sensor, is defined and bounds a first portion of the recorded image, wherein the first tilt angle is defined depending on the folding angle. The first portion which is bounded by the tilted first bounding frame is transmitted to the first or second display and displayed by the first or the second mechanically tilted display while maintaining the orientation of the recorded image relative to the observed scene or relative to the horizontal, that is, without rotating the recorded image or the image portion relative to the observed scene or relative to the horizontal.
