Title: Jin Ogasawara: Innovator in Image Processing Technology

Introduction

Jin Ogasawara is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of image processing, holding a total of 7 patents. His innovative work focuses on enhancing image quality through advanced processing techniques.

Latest Patents

Ogasawara's latest patents include an image processing apparatus and method designed to sharpen input images. This technology involves up-converting the input image to increase the pixel count, which allows for the generation of higher frequency components than those present in the original image signal. By reducing the number of multipliers required, his invention achieves significant downsizing of the apparatus and cost reduction. The image processing apparatus features a path for up-converting the input image signal and a sharpening processing side that performs nonlinear arithmetic processing. This includes a filter that can either remove noise or eliminate DC components, enhancing the overall image quality.

Another notable patent involves sharpening images using frequency components that exceed the Nyquist frequency. This apparatus generates an output image by applying nonlinear processing to the input image signal, followed by sharpening processing to create a second signal with higher frequency components. The final output image signal is produced by combining this second signal with the original input image signal.
