Title: The Innovative Contributions of Osamu Oka
Introduction
Osamu Oka is a prominent inventor based in Kumamoto, Japan. He has made significant contributions to the field of solid-state imaging technology. With a total of five patents to his name, Oka's work has had a substantial impact on electronic apparatuses and imaging modules.
Latest Patents
Oka's latest patents include a solid-state imaging device, an electronic apparatus, a lens control method, and an imaging module. The solid-state imaging device features a pixel region with a two-dimensional matrix pattern of pixels. Some of these pixels are designed as phase difference detection pixels, which include a photoelectric conversion section on a semiconductor substrate and a light blocking film positioned above part of the photoelectric conversion section. Notably, the location of the light blocking film varies depending on the position of the phase difference detection pixel within the pixel region. For instance, the light blocking film for a pixel at the edge of the region differs from that of a pixel located at the center.
Another patent describes a solid-state image pickup apparatus that consists of an image pickup pixel and a focus detection pixel. The image pickup pixel is equipped with a micro lens and a photoelectric conversion unit that captures light from the micro lens. The focus detection pixel also includes a micro lens, a photoelectric conversion unit, and a light shielding unit that blocks part of the light incident on the photoelectric conversion unit. In this apparatus, the micro lens is uniformly formed across both pixel types, and the focus detection pixel features a high refractive index film beneath the micro lens.
