Title: Ke-Hua Lan: Innovator in Cinematographic Technology
Introduction
Ke-Hua Lan is a notable inventor based in Grenoble, France. He has made significant contributions to the field of cinematographic technology, holding a total of 2 patents. His innovative work focuses on methods and devices that enhance the visual restoration of digital images.
Latest Patents
One of his latest patents is an installation for exposing a cinematographic film from digital images. This installation includes a light source, means for storing film photoresist for exposure and exposed photoresist, and a film carrier for positioning the film photoresist at an exposure plane. It also features a projection lens capable of projecting digital images at the exposure plane, a liquid crystal matrix for displaying the various digital images, and a retractable mirror oriented at 45° to the optical axis of the projection lens. An image analysis device is symmetrically positioned with respect to the exposure plane, allowing it to receive images transmitted by the liquid crystal matrix. The signals detected are processed using associated software to set the characteristics of the optical members of the installation.
Another significant patent is a method for transferring a digital image to visually restore it. This method involves associating an array of microlenses with a transparent LCD screen at its input face, upstream from a black mask. Each cell of the LCD is paired with a microlens from the array. A telecentric projection lens enhances the sharpness and uniformity of the image during visual restoration. The method verifies the angle of divergence of an incident beam of exposure or illuminating light, and the LCD screen or each pixel is laterally offset at least once on the projection surface. One or several exposures are taken of each of these offset projections.
