Claim:
An image processing apparatus comprising: an acquiring unit that acquires a display request including a first external apparatus identification information capable of identifying a first external apparatus and screen identification information capable of identifying a screen from the first external apparatus; a storage unit that stores external apparatus screen information in which the first external apparatus identification information and the screen identification information acquired by the acquiring unit are associated with each other; an update unit that updates the first external apparatus screen information whenever the display request is acquired; a determining unit that determines a polling interval for the first external apparatus on the basis of the external apparatus screen information stored in the storage unit; and a transmitting unit that transmits, to the first external apparatus, screen data which includes information of the determined polling interval and is displayed on a screen corresponding to the display request, wherein, when a second external apparatus identification information item corresponding to the same screen identification information as that included in the display request is stored in the storage unit, the determining unit determines the polling interval for the first external apparatus as a first polling interval, and when the second external apparatus identification information item is not stored in the storage unit, the determining unit determines the polling interval for the first external apparatus as a second polling interval, wherein the first polling interval is smaller than the second polling interval.
