Title: Eiichiro Tomonaga: Innovator in Image Processing Technology

Introduction

Eiichiro Tomonaga is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of image processing, holding a total of 4 patents. His work focuses on enhancing image quality and processing efficiency, which has implications in various technological applications.

Latest Patents

Tomonaga's latest patents include an image processing apparatus and method. This invention features a scaling converter that transforms a first image signal into a second image signal with a higher pixel count. Additionally, it incorporates a luminance histogram detector that identifies the luminance histogram of the image. A determination module assesses whether the second image signal contains a graphics image based on the histogram data. The super resolution processor then enhances the second image signal to create a third image signal with superior resolution, applying sharpening techniques based on a reference gain. Notably, when the second image signal includes a graphics image, the processor adjusts the sharpening gain accordingly.

Another significant patent is a video signal processing device and method. This invention utilizes a buffer to delay an input luminance signal by one frame period. A screen unit motion detection section discerns whether the input signal represents a moving or static image, providing a gradual determination result. The device employs a subtracter to generate a differential signal by subtracting the delayed luminance signal from the input signal. Furthermore, a pixel unit motion detector identifies pixel motion using multiple level values within a specified range. A limiter then regulates the differential signal based on the motion detection results, while an adder combines the output signal with the input luminance signal.
