Title: Takashi Matsushita: Innovator in Display Technology

Introduction

Takashi Matsushita is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of display technology, holding a total of 15 patents. His work focuses on enhancing the quality and functionality of display apparatuses and network printing systems.

Latest Patents

One of Matsushita's latest patents is for a display apparatus and display method. This invention allows for appropriate and accurate focusing of images displayed on a unit. The process involves storing an image in a first storage unit, moving the focus position of the image with a movement unit, and storing the newly focused image in a second storage unit. A comparison unit then analyzes the images on a pixel basis, extracting areas with changes in pixel state. A calculation unit determines the contrast value in these areas, and a determination unit assesses changes in the contrast values. Finally, a change unit modifies the attributes of the pixels in the extracted image area based on the determination results.

Another notable patent is for a network print system, along with an information processing apparatus and its control method. This system aims to print high-quality image data, such as forms generated using a web browser. When a form image is displayed on a client’s web browser and a print process is initiated, the instruction is sent to a server. The server then searches for an appropriate template in a form template storage unit, merges it with the data using an image generation unit, converts the merged data into PDL data through a print output unit, and prints the high-quality image from a printer.

Career Highlights

Matsushita is currently employed at Canon Kabushiki Kaisha, a leading company in imaging and printing technology. His innovative work has significantly advanced the capabilities of display and printing systems, making them more efficient and user-friendly.
