• activate the camera in response to a request, and store an image captured through the camera,
• in response to the search command, control the first AI agent to convert the search command into converted text and extract the search keyword from the converted text,
• identify whether the first AI agent is interconnected with the second AI agent and determine a transmission path of the search keyword,
• transmit the search keyword to the second AI agent according to the determined transmission path,
• create category information defining a type of the captured image via the second AI agent,
• match the captured image with the category information and store the matched information,
• retrieve the at least one piece of image information corresponding to the search keyword from the pre-stored image information using the category information,
