Information processing apparatus and method

A server apparatus renders a process result of software on an image memory that stores a display image to be displayed on a client terminal, detects an update area in which an update occurs between frames of an image. The server apparatus selectively switches and performs a first generation process and a second generation process according to the number of detected update areas.
