Latest Patents

Kawanobe'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 of pixels. Notably, some 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. The location of the light-blocking film varies depending on the pixel's position within the pixel region, with different placements for pixels at the periphery compared to those in the center.

Another significant patent addresses a data storage device and an error processing method in its read processing. This invention aids disk drives in effectively managing data address mark detection errors. The data sector is equipped with multiple data address marks, allowing the read/write (RW) channel to utilize part of these marks during data retrieval. Each section of a split sector contains two data address marks, and the RW channel selects one based on a specified register. In the event of a detection error, the position is recorded, enabling the error recovery processing section to determine the appropriate data address mark for subsequent retries.
