Camera device, compartment-interior imaging system, and compartment-interior-information acquisition device
A camera device of one embodiment is provided with an image capturing unit configured to capture image of a room interior; a receiving unit configured to receive an image capturing instruction for capturing image of the room interior by way of a home appliance; and a camera-side controller being configured to standby in a low-power mode consuming relatively less electric power compared to a normal-operation mode and being configured to capture image of the room interior through the image capturing unit by returning to the normal-operation mode when the receiving unit receives the image capturing instruction.
1. A camera device comprising:
a camera provided inside a refrigerator and configured to capture an image of a room interior inside the refrigerator;
an optical sensor configured to receive an image capturing instruction for capturing the image of the room interior encoded in an optical energy emitted according to a predetermined pattern by an in-room lighting provided inside the refrigerator;
and a controller configured to standby in a low-power mode consuming relatively less electric power compared to a normal-operation mode and configured to capture the image of the room interior through the camera by returning to the normal-operation mode when the optical sensor detects the optical energy emitted according to the predetermined pattern by the in-room lighting.
2. The camera device according to claim 1 , wherein the controller is configured to capture the image of the room interior when a pattern of energy detected by the optical sensor matches the pattern of energy given as the image capturing instruction.
3. The camera device according to claim 2 , wherein the controller is configured to switch to the low-power mode when the pattern of energy detected by the optical sensor and the pattern of energy given as the image capturing instruction do not match and when image capturing by the camera is completed.
4. An in-room image capturing system comprising:
a refrigerator;
a camera device provided inside the refrigerator and including a camera configured to capture an image of a room interior inside the refrigerator, an optical sensor configured to receive an image capturing instruction for capturing the image of the room interior encoded in an optical energy emitted according to a predetermined pattern by an in-room lighting provided inside the refrigerator, and a controller configured to standby in a low-power mode consuming relatively less electric power compared to a normal-operation mode and configured to capture the image of the room interior through the camera by returning to the normal-operation mode when the optical sensor detects the optical energy emitted according to the predetermined pattern by the in-room lighting;
an operation terminal configured to input the image capturing instruction to the camera device; and a home appliance provided with a transceiver communication unit configured to receive the image capturing instruction given by the operation terminal and a transmitting unit the in-room lighting configured to transmit the image capturing instruction received by the transceiver communication unit to the camera device by emitting the optical energy according to the predetermined pattern.
5. An in-room information acquiring device comprising: a sensor provided inside a refrigerator configured to acquire information of a room interior inside the refrigerator;
an optical sensor configured to receive an acquiring instruction given to the information acquiring unit encoded in an optical energy emitted according to a predetermined pattern by an in-room lighting provided inside the refrigerator;
and a controller configured to standby in a low-power mode consuming relatively less electric power compared to a normal-operation mode and configured to control the sensor to acquire the information of the room interior by returning to the normal-operation mode when optical sensor detects the optical energy emitted according to the predetermined pattern by the in-room lighting.
