Title: Masahiro Haraguchi: Innovator in Projection Technology
Introduction
Masahiro Haraguchi is a prominent inventor based in Daito, Japan, known for his significant contributions to projection technology. With a total of nine patents to his name, Haraguchi has made remarkable advancements in optical modulation and video projection devices.
Latest Patents
One of his latest patents is a projection display apparatus that features an optical modulator element. This element modulates incident light from a light source using an input signal. A projection lens then magnifies and projects the outgoing light from the optical modulator element. Additionally, a pixel shift element is positioned between the optical modulator element and the projection lens, displacing the optical path of the outgoing light. This innovation allows for the shifting of a display position of a pixel on a screen in a given cycle between two positions. The controller manages the pixel shift element, enabling shifts at varying speeds.
Another notable patent is a video projection device and method that controls the light source based on an image signal. This device includes a splitter that divides the light flux emitted from a light source into multiple colors in a time-divisional manner. The video display element modulates the light based on an input image signal to form an image. A controller calculates light intensity and adjusts the light source accordingly.
