Storage device for part of monitor screen image

摘要

The device uses an adhesive film (4) of photosensitive material (2), which is effective on the monitor side to store the image information. This is especially applicable to a code, which is displayed on a part of a monitor, particularly a television screen. The photosensitive material is sensitive to light of a certain wavelength range, and contains fluorescent material (3) for converting any light outside the sensitivity range into light within the range. The fluorescent material may be located between the photosensitive material and a reflective layer.
