Title: Arnaud Defernez: Innovator in Image Sensor Technology

Introduction

Arnaud Defernez is a notable inventor based in Breda, Netherlands. He has made significant contributions to the field of image sensor technology, particularly with his innovative patent that enhances image capture capabilities.

Latest Patents

Defernez holds a patent for a technology titled "Shared photodiode reset in a 5 transistor-four shared pixel." This invention focuses on an image sensor that provides global shutter scanning with exposure time control during image capture. The image sensor features a pixel array with shared pixel units, each containing four photodiodes with a floating diffusion node shared between them. Additionally, it includes respective global shutter gates positioned between each photodiode and the supply voltage of the pixel array. An image capture timing controller is responsible for managing the exposure time of each photodiode by adjusting the width of a global shutter reset pulse applied to the global shutter gates after each readout cycle during image capture. This innovation allows for the modification of the respective exposure time of each shared pixel unit.
