Title: Innovations of Joon-Chok Lee

Introduction

Joon-Chok Lee is a prominent inventor based in Penang, Malaysia. He has made significant contributions to the field of optical sensors and navigation devices. With a total of 11 patents to his name, Lee continues to push the boundaries of technology through his innovative designs.

Latest Patents

One of his latest patents is an optical sensor that synchronizes to ambient light flicker and its operating method. This invention includes a photodiode that detects ambient light flicker to generate sine waves. The sine waves are then converted to square waves by a wave converter. A processor uses a sampling frequency to count these square waves, determining whether the ambient light flicker is accurately detected. This technology allows for adjustments in the acquiring phase of the image frame based on the counting values.

Another notable patent is a navigation device capable of estimating contamination and determining an update threshold. This device features an image sensor that outputs successive image frames. The processing unit calculates the contamination level and motion signal based on filtered image frames. It then decides whether to update a fixed pattern noise (FPN) stored in a frame buffer, optimizing the update process based on various calculated parameters.
