Control method executed in information processing apparatus, information processing system, and non-transitory computer readable storage medium

An information processing system including an information processing apparatus and an external apparatus that are connected via a network,

• wherein the information processing apparatus comprises:
• an image obtainment unit configured to obtain a captured image of a liquid container acquired by capturing an image using an image-capturing unit;
• a first identifier obtainment unit configured to obtain a first identifier for uniquely identifying the liquid container from the captured image;
• a detection unit configured to detect a remaining amount of liquid in the liquid container by analyzing the captured image;
• and a transmission unit configured to transmit the first identifier and the remaining amount of liquid to the external apparatus via the network, and
• the external apparatus stores the first identifier being associated with the remaining amount of liquid.

An information processing system including an information processing apparatus and an external apparatus that are connected via a network,

• wherein the information processing apparatus transmits a captured image of a liquid container acquired by capturing an image using an image-capturing unit, and
• the external apparatus comprises:
• a first identifier obtainment unit configured to obtain a first identifier for uniquely identifying the liquid container from the captured image;
• a detection unit configured to detect a remaining amount of liquid in the liquid container by analyzing the captured image;
• and a storage unit configured to store the first identifier being associated with the remaining amount of liquid.

A non-transitory computer readable storage medium storing a program for executing a control method of an information processing apparatus, the control method comprising the step of:

• Obtaining a captured image of a liquid container obtained by capturing an image using an image-capturing unit;
• obtaining a first identifier for uniquely identifying the liquid container from the captured image;
• detecting a remaining amount of liquid in the liquid container by analyzing the captured image;
• and
• transmitting the first identifier and the remaining amount of liquid to an external apparatus.
