Method for transferring a digital image so as to visually restore said digital image, and device for carrying out said method |
摘要 |
A method for visually restoring a digital image that is displayed on a transparent LCD screen includes associating an array of microlenses with the LCD screen at the input face thereof, upstream from a black mask. Each of cells of the LCD is associated with a microlens of the array. A telecentric projection lens increases the sharpness and uniformity of the image during the visual restoration thereof. The angle of divergence of an incident beam of exposure or illuminating light is verified. The LCD screen or each pixel of the image displayed on the LCD screen is laterally offset at least once on the projection surface by means of a body. One or several exposures are taken of each of said offset projections.
