Abstract
A refrigerator system capable of reducing decrease in the accuracy of detecting change in a storage state and reducing a communication load for transmitting images of the inside of a storeroom, which are taken at a plurality of viewpoints to the outside of a refrigerator is provided. To achieve this, the refrigerator system includes: a camera configured to take the images of the inside of the storeroom; a camera moving device configured to move the camera at least in the vertical direction; a communication device configured to transmit the images taken by the camera to the outside of a main body; and a change detecting device configured to detect change in a food-item storage state of each shelf based on the images taken by the camera. The camera takes images of each shelf at a first viewpoint and a second viewpoint. The change detecting device detects change in the food-item storage state of the shelf based on the image taken at the first viewpoint. The communication device transmits, for the shelf, change in the food-item storage state of which is detected, both images taken at the first viewpoint and the second viewpoint to the outside of the main body.
