Title: Woo Suk Ha: Innovator in Display Technology

Introduction

Woo Suk Ha is a prominent inventor based in Yongin-si, South Korea. He has made significant contributions to the field of display technology, holding two patents that showcase his innovative approach to improving image quality in liquid crystal displays.

Latest Patents

One of his latest patents is an "Inverse Tone Mapping Method." This invention provides a technology that separates a low-contrast-ratio image into sublayer images. It classifies each sublayer image into several categories based on their characteristics and learns a transformation matrix that represents the relationship between the low-contrast-ratio image and a high-contrast-ratio image for each category. Additionally, this technology separates an input low-contrast-ratio image into sublayer images, selects a category for each sublayer image, and applies a learned transformation matrix to generate a high-contrast image.

Another notable patent is for a "Liquid Crystal Display Apparatus and Driving Method Thereof." This invention addresses the issue of picture quality deterioration caused by signal distortion in liquid crystal display devices. It selects an area within an image that has rapidly changing gamma voltage, identifies a border between different intensity regions, computes an average intensity within that area, and adjusts the gamma voltage for each pixel based on the average intensity. The liquid crystal display device includes a panel, an analyzer for brightness characteristics, an average video signal voltage generator, a bordering value processing part, and a weighting part for pixel voltage adjustment.
