Image capturing device and activation method therefor
First Claim
1. A portable apparatus having a function of image capturing comprising:
- a processor including one or a plurality of control units;
a plurality of types of sensors including an image sensor, said sensors having respective outputs of multiple types capable of being input to said processor;
a display configured to display an image based on an image signal from said image sensor; and
a power supply unit to supply power to said processor, said sensors and said display,wherein said portable apparatus is operable in a plurality of powered operational states including a first operational state and a second operational state, an image capturing operation being performable in the first operational state,wherein said portable apparatus changes its operational state from the second operational state to the first operational state and said power supply unit supplies power to one or a plurality of components of the portable apparatus including said image sensor when receiving a first signal representing an activation of the image capturing operation in the second operational state according to a result of the output of one or a plurality of said sensors,wherein said portable apparatus changes its operational state from the first operational state to a monitoring state and reduces power consumption of said display when there is not a second signal detected in a predetermined period, andwherein at least one of said control units has a variably controllable operating frequency and controls the image capturing operation in the first operational state, and said operating frequency can be lowered so that power consumption of said at least one of the control units can be lower than other of said control units that control operation other than the image capturing operation.

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.

9. A processor for a portable apparatus, wherein the portable apparatus comprises a display and a plurality of types of sensors, said types of sensors including an image sensor, wherein said portable apparatus is operable in a plurality of powered operational states, said powered operational states including a first operational state and a second operational state, and an image capturing operation is performable in the first operational state,
wherein said sensors have respective outputs of multiple types capable of being input to said processor, wherein said processor includes one or a plurality of control units, at least one of said control units having a variably controllable operating frequency and controlling the image capturing operation in the first operational state, wherein said processor is to control said portable apparatus to (1) change its operational state from the second operational state to the first operational state and (2) supply power to one or a plurality of components of the portable apparatus including said image sensor when receiving a first signal representing an activation of the image capturing operation in the second operational state according to a result of the output of one or a plurality of said sensors, wherein said processor is to control said portable apparatus to (1) change its operational state from the first operational state to a monitoring state and (2) reduce power consumption of said display when there is not a second signal detected in a predetermined period, and wherein said operating frequency can be lowered so that power consumption of said at least one of the control units can be lower than other of said control units that control operation other than the image capturing operation.
