Image capturing device and activation method therefor
First Claim
1. A portable apparatus comprising:
- a plurality of sensors including an image sensor,wherein said portable apparatus is operable in a plurality of powered operational states including a first operational state and a second operational state, and when in the first operational state the portable apparatus is adapted to perform an image capturing operation; and
a processor including;
a plurality of connections corresponding to and interconnected with the plurality of sensors; and
one or more control units, at least one of said control units having a variably controllable operating frequency,wherein said processor is to control said portable apparatus to change operational state of said portable apparatus from the second operational state to the first operational state and to control said portable apparatus to supply power to one or a plurality of components of the portable apparatus including said image sensor, in response to receiving a first signal representing an activation of the image capturing operation in the second operational state according to output of one or a plurality of said sensors,wherein the operational state is changed while the processor is performing background processing, andwherein at least one of the control units has at least two power consumption states, in which power consumption in one of the power consumption states is less than power consumption in another of the power consumption states.

Abstract
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.
