Title: Maki Koizumi: Innovator in Video Signal Processing
Introduction
Maki Koizumi is a prominent inventor based in Yokohama, Japan. She has made significant contributions to the field of video signal processing, holding a total of 3 patents. Her work focuses on enhancing the efficiency and accuracy of motion vector detection in video technology.
Latest Patents
Maki Koizumi's latest patents include a "Video signal processing apparatus and method." This invention features a frequency distribution monitor unit that partitions the size of a vertical component of a motion vector into multiple classes. It detects the frequency of occurrences of the vertical component in each class. When the vertical component exceeds a predetermined threshold in specific classes, the offset control unit generates offset signals to shift read addresses in the vertical direction. Additionally, a selection control unit manages the vertical shifting of pixel data selected by delay selection units.
Another notable patent is the "Motion vector detecting apparatus and motion vector detecting method." This apparatus includes a correlation detecting unit, a repetitive object detecting unit, and a motion vector detecting unit. The correlation detecting unit identifies correlations among multiple pieces of pixel data in various directions. The repetitive object detecting unit determines whether the pixel data, where a motion vector is to be detected, is part of a repetitive object. The motion vector detecting unit then reduces the difference value in the direction of the detected motion vector, enhancing the accuracy of motion vector detection.
