Title: Keiko Hirayama: Innovator in Frame Generation Technology

Introduction

Keiko Hirayama is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of image processing, particularly in the development of technologies that enhance video quality through interpolation techniques. With a total of 6 patents to her name, her work has had a substantial impact on the industry.

Latest Patents

Hirayama's latest patents include an interpolation frame generation apparatus, an interpolation frame generation method, and a broadcast receiving apparatus. According to one embodiment, the interpolation frame generation apparatus generates an interpolation frame image to be inserted between continuous frame images. This apparatus includes a motion vector detection module and a generation module. The motion vector detection module executes block matching processing in each of a plurality of blocks included in the continuous frame images and specifies one motion vector on an interpolation frame. The generation module generates an interpolation frame image based on the specified motion vector or, in cases where no motion vector is detected, generates an interpolation frame image based on the frame image containing no motion vector component.

Another embodiment describes an interpolated frame generator that comprises a first detector, which detects potential motion vectors by block matching between input frame images using a first block of fixed size. A second detector detects motion vectors using a larger block size. The generator then creates an interpolated frame based on the detected motion vectors, ensuring high-quality image output.
