Latest Patents

Masatoshi Arai holds a patent for an image sensor, semiconductor device, and image sensing method. This invention allows for the acquisition of image signals with a high signal-to-noise (S/N) ratio during rapid image pickup operations. The design involves an input transfer stage of CCD memory, where signal charges are processed efficiently. The final transfer stage is connected to the input transfer stage, enabling the transfer of signal charges in a systematic manner. In accumulation mode, the read gate and drain gate remain off, allowing for the next transfer operation of the CCD memory. The accumulated signal charges are transferred stage by stage, and the signal charges obtained during the first image pickup timing are transferred directly to the input transfer stage. This innovative approach allows newly obtained signal charges from the photoelectric conversion section to be injected into the input transfer stage, resulting in the integration of signal charges from multiple image pickups.
