Upon receiving a communication switching instruction from a first wireless access point used for communication with an image processing apparatus, an image display apparatus disconnects communication with the first wireless access point. Simultaneously, the image display apparatus transmits, to a second wireless access point, a link request to establish communication with the second wireless access point of a new communication destination included in the switching instruction. The image display apparatus displays, on a display unit, a captured image continuously acquired from am image capturing unit until switching from the first wireless access point to the second wireless access point finishes as communication destination switching.
