Patent number: 11758302Abstract: An imaging device includes a controller, a power supply, a regulator, and a switch. The controller is configured to control an imaging unit, on the basis of a command and data that are received from a host in accordance with an I2C/I3C communication protocol. The power supply is configured to supply a voltage to a digital block of the controller. The digital block is configured to be subjected to dynamic voltage frequency scaling within one-frame operation. The regulator and the switch are provided between the digital block and the power supply, and coupled in parallel with each other.Type: GrantFiled: September 3, 2021Date of Patent: September 12, 2023Assignee: Sony Semiconductor Solutions CorporationInventors: Chiaki Takano, Toshimasa Shimizu, Yuki Takizawa, Mark Pude, Hirotaka Murakami, Kevin Fronczak

Patent number: 11705473Abstract: An imaging device includes a photodetector and an optical filter disposed on a light-receiving surface of the photodetector. The optical filter may include a diffraction grating, a core layer, and a reflector disposed on first and second opposing sides of the core layer. In some cases, the optical filter (e.g., a GMR filter) uses interference of electromagnetic waves on an incidence plane of light or a plane parallel to the incidence plane. The reflector may reflect electromagnetic waves between adjacent optical filters. The present technology can be applied to, for example, an image sensor provided with a GMR filter, such as a back-side-illuminated or front-side-illuminated CMOS image sensor.Type: GrantFiled: January 6, 2022Date of Patent: July 18, 2023Assignee: Sony Semiconductor Solutions CorporationInventors: Sozo Yokogawa, Hirotaka Murakami, Mikinori Ito
