Title: Terence W Mead: Innovator in Film Scanning Technology

Introduction

Terence W Mead is a notable inventor based in Hertford, GB, recognized for his contributions to film scanning technology. With a total of 12 patents to his name, Mead has made significant advancements in the field, particularly in optical scatter correction and film stability.

Latest Patents

One of Mead's latest patents focuses on optical scatter correction for film scanners. This invention involves a film scanner that utilizes diffuse illumination and an array sensor, such as a line array or area array CCD. The design includes an integrating optical element in the form of an integrating sphere, which provides diffuse illumination to the film. This illumination improves the light level reaching the array sensor, especially from film that has been scattered by defects like scratches. The invention also features a lens at the exit aperture of the integrating sphere, which helps define a specific area from which light that is not scattered by the film is derived. Additionally, an extra light source can be included to enhance the visibility of scratches, allowing for a separate signal to correct the main image signal.

Another significant patent addresses the correction of film instability based on the movement of the video image. In this invention, film unsteadiness in a flying spot film scanner is measured by examining spatial and temporal differences around a given pixel. A correction signal is generated and applied as feedback to the X and Y circuits of the scan generator, ensuring improved image stability.
