Title: Masaaki Kisou: Innovator in Image Processing Technology

Introduction

Masaaki Kisou is a prominent inventor based in Chiba, Japan. He has made significant contributions to the field of image processing technology, holding a total of 4 patents. His work focuses on enhancing image display and reducing noise in television receivers.

Latest Patents

Masaaki Kisou's latest patents include an innovative image track display apparatus. This apparatus features a memory that delays an image signal by at least one vertical scanning period. It incorporates a first subtraction circuit that generates a first difference signal between the image signal and its delayed counterpart. The first difference signal consists of first and second polarity components. A non-linear processing circuit then multiplies one polarity component by K times (where 0 < K < 1) while reducing the other polarity component to zero when it exceeds a prescribed value. Additionally, a second subtraction circuit takes a second difference signal between the output of the non-linear processing circuit and the original image signal. Finally, a display device showcases the delayed image signal obtained through the memory circuit.

Another notable patent is a noise reduction circuit for a chrominance signal used in television receivers. This circuit is designed to minimize noise in the chrominance signal. It includes a decoder for decoding first and second color difference signals, which contain noise components from the received chrominance signal. A signal subtraction circuit generates first and second frame difference signals in response to two successive color difference signals. A signal converting circuit extracts compensation signals from these frame difference signals. The noise reduction circuit then reduces noise from the color difference signals based on these compensation signals. A discrimination circuit determines whether both frame difference signals are below a prescribed level, generating a control signal accordingly.
