Title: Kazuhiro Tanabe: Innovator in Image Processing Technology

Introduction

Kazuhiro Tanabe is a prominent inventor based in Iruma, Japan. He has made significant contributions to the field of image processing, holding a total of eight patents. His work focuses on enhancing the quality of video signals in imaging devices, particularly in color television cameras.

Latest Patents

Among his latest patents are an image processing apparatus and an image processing method. These innovations aim to achieve both a high signal-to-noise ratio and a wide dynamic range of the output video signal from a one-CCD color television camera. The image signal processing apparatus utilizes a solid-state image sensor with different color filters arranged strategically. It includes an amplifying unit that boosts color signals from the sensor, a separating unit that divides these signals into individual color components, and a white balance adjusting unit that fine-tunes the color signals. Additionally, a level detecting unit monitors the saturation level of the adjusted signals, while a correction signal generating unit creates necessary adjustments based on the detected saturation. The first adding unit then combines these correction signals with the adjusted color signals.

Another notable patent is the image pickup apparatus, which features an image pickup device with pixels coated in various color filters. This apparatus includes a separation unit that extracts three color image signals from the video output of the pixels. It also has an adjustment signal generation unit that produces color balance and hue adjustment signals, which are used by an adjustment unit to refine the video output.
