An information processing device includes a memory; and a processor coupled to the memory, wherein the processor executes a process comprising: drawing an image representing a processing result based on software into an image memory; identifying a high-frequency change area; animating an image of the high-frequency change area; adding time information to an image of a change area having a change or the image of the high-frequency change area animated, and transmits the image to a terminal device; receiving the time information from the terminal device; determining based on a difference between the received time information and a reception time of the time information whether image drawing delay occurs; and starting an animation of the change area when the image drawing delay occurs and the animation is not being executed or changes an image transmission interval when the image drawing delay occurs and the animation is being executed.
