CAMERA DEVICE, COMPARTMENT-INTERIOR IMAGING SYSTEM, AND COMPARTMENT-INTERIOR-INFORMATION ACQUISITION DEVICE

摘要

A camera device (2) in an embodiment is provided with the following: an imaging unit (11) that images the interior of a compartment; receiving means (a light sensor (14), a sound sensor (19), and a vibration sensor (20)) for receiving, via a household electrical appliance (a refrigerator (1)), an imaging instruction for imaging the interior of the aforementioned compartment; and a camera-side control unit (18). Most of the time, the camera-side control unit (18) is on standby in a low-power mode, the power consumption of which is less than that of a normal operating mode, but when an imaging instruction is received by the receiving means (light sensor (14), sound sensor (19), and vibration sensor (20)), the camera-side control unit (18) reverts to said normal operating mode and uses the imaging unit (11) to image the interior of the compartment.
