Latest Patents

Asahi’s patent, “Imaging Element and Imaging Device,” addresses how to generate phase-difference signals while preventing a reduction in saturation charge. The disclosed pixel includes multiple photoelectric conversion sections that convert incident light into charge, along with separators that isolate sections and pixels. An overflow path allows excess charge to move between photoelectric conversion sections, while an overflow gate adjusts the path’s potential. Charge-transfer sections move generated charge to a charge-holding section, which supports the generation of an image signal.

Career Highlights

Asahi’s listed patent reflects work on pixel architecture and charge management in imaging devices. These features are designed to support phase-difference signal generation while preserving charge capacity.

Collaborations

Asahi is associated with Sony Semiconductor Solutions Corporation. His listed coworker is Hiroki Tojinbara.

Conclusion

Toshihiro Asahi’s patent describes an imaging-device design that manages charge within pixels to support phase-difference signals and maintain saturation capacity.
