Application: Image capturing apparatus, control method, and storage medium (Patent ID: US20240048865A1)

The patent filed by Canon Inc. describes an image capturing apparatus that includes an image sensor, power supply circuit, and power storage device. The apparatus is designed to control power distribution based on the operational state of the device. In a first state, power is supplied from the power supply circuit to the image sensor without using the power storage device. However, in a second state with higher power consumption, power is supplied from both the power supply circuit and the power storage device to the image sensor. The apparatus is capable of determining the usability of the power storage device based on factors like temperature and equivalent series resistance.

Additionally, the patent outlines specific modes of operation for the image capturing apparatus, such as still image mode and moving image mode, with corresponding power consumption levels. The apparatus is equipped with a control unit that manages the charging of the power storage device based on the operational requirements, ensuring efficient power utilization. Furthermore, the patent details the use of different types of power storage devices, such as electrical double-layer capacitors or all-solid-state batteries, in conjunction with the power supply circuit to optimize power distribution in various operational states of the image capturing apparatus.
