1. An artificial intelligence refrigerator, comprising:
a depth sensor;
an inner door;
an outer door having a transparent display;
one or more cameras provided in the outer door;
a second sensor configured to detect at least an opening of the outer door, a closing of the outer door or an angle that the outer door is opened; and
at least one processor configured to:
determine whether the angle is greater than or equal to a preset angle based at least in part on detecting a movement of the outer door,
cause a camera from among the one or more cameras to capture an image of the inner door based at least in part on the angle being determined to be less than the preset angle,
determine a storage state of food items located in the inner door based on the captured image,
cause a display, on the transparent display, of food management information associated with the food items based on the determined storage state,
partition the inner door and an inner storage compartment located inside the inner door based at least in part on a depth image obtained through the depth sensor, and
distinguish a region corresponding to the partitioned inner storage compartment from the captured image, wherein the storage state is obtained based at least in part on the captured image including the distinguished region.
 
14. An artificial intelligence (AI) refrigerator, comprising:
a depth sensor;
an inner door;
an outer door having a transparent display;
one or more cameras provided in the outer door;
a second sensor configured to detect at least an opening of the outer door, a closing of the outer door or an angle that the outer door is opened;
a communication interface configured to communicate with an AI server, and
at least one processor configured to:
determine whether the angle is greater than or equal to a preset angle based at least in part on detecting a movement of the outer door,
cause a camera from among the one or more cameras to capture an image of the inner door based at least in part on the angle being determined to be less than the preset angle,
transmit, to the AI server, the captured image through the communication interface,
receive, from the AI server, a storage state of food items located in the inner door based on the transmitted captured image and food management information associated with the food items,
cause a display, on the transparent display, of the received food management information based on the received storage state,
partition the inner door and an inner storage compartment located inside the inner door based at least in part on a depth image obtained through the depth sensor, and
distinguish a region corresponding to the partitioned inner storage compartment from the captured image, wherein the storage state is obtained based at least in part on the captured image including the distinguished region.
