Title: Albert J Theuwissen: Innovator in Charge Coupled Imaging Devices

Introduction

Albert J Theuwissen is a notable inventor based in Bree, Belgium. He is recognized for his contributions to the field of imaging technology, particularly in the development of charge coupled devices (CCDs). His innovative approach has led to advancements that enhance the functionality and versatility of imaging systems.

Latest Patents

Theuwissen holds a patent for a charge coupled imaging device that features an adjustable aspect ratio. This invention allows for the adjustment of the width/height ratio in charge coupled imaging devices by selectively using columns on either side of the imaging matrix. The technology enables a reduction in aspect ratio from 16/9 to 4/3, which is particularly relevant for applications such as widescreen televisions. However, it has been observed that this reduction can impair image quality in the 4/3 mode. The invention proposes using an FT device with a 4/3 aspect ratio operated as a 4-phase CCD, while also allowing for a 16/9 aspect ratio by reducing the height of the device through the non-use of selected lines. This innovative approach maintains the width and vertical line count, ensuring that the aspect ratio remains substantially equal to 16/9.

Career Highlights

Theuwissen has made significant strides in his career, particularly through his work with U.S. Philips Corporation. His expertise in imaging technology has positioned him as a key figure in the development of advanced imaging solutions.
