Abstract:
1. A hand-held telescopic real-time observation instrument for distant objects, comprising at least one line-of-sight viewing system, each line-of-sight viewing system being provided with a set of optical lenses, having a first-zoom state, and having electronic retina means registering a presented real-time observation, and an electronic display screen showing an image of said presented real-time observation, wherein said display screen has two display modes: a real-time display mode, and a still-image display mode, said display screen being adapted to exclusively show only one display mode at a time at the choice of a user of said instrument by control means, wherein said display screen in said still-image display mode freezes said presented real-time observation and said instrument assumes a second zoom-state in order to further magnify said frozen image, wherein an eye of a user need not change viewing position when changing between said two display-modes, wherein said optical system includes a set of optical lenses for providing enlargement in said first mode and said electronic retina means provides a higher degree of magnification and a lower field of vision as compared to the first mode, when in said second mode.
