IMAGE CAPTURING DEVICE AND ACTIVATION METHOD THEREFOR

摘要

An image capturing device includes a first controller operable to control image capturing; an operation section including a switch; a detector operable to detect a change to an image capturing mode and to send a signal representing the change; a second controller operable to monitor and process the sent signal, the second controller having a power consumption less than that of the first controller; and a power supply operable to supply power to the first controller, the second controller, and a functional section of the device. When the second controller receives the signal sent from the detecting section in a power saving state in which power is supplied from the power supply to the second controller, the power saving state is changed to a power supplying state capable of image capturing by supplying power from the power supply to portions of the device including the first controller.

主权项

1. An image capturing device, comprising:
first control means for controlling image capturing, the first control means having a first power consumption; operation means including a switch; detecting means for detecting a change to an image capturing mode and for sending a signal representing the change to the image capturing mode; second control means for monitoring and processing the signal sent from the detecting means, the second control means having a power consumption less than the first power consumption; and a power supply for supplying power to the first control means, the second control means, and a functional section of the image capturing device, wherein a power saving state is changed to a power supplying state capable of image capturing by supplying power from the power supply to portions of the image capturing device including the first control means when the second control means receives the signal representing the change to the image capturing mode from the detecting means.
