An image processing apparatus that provides multiple services for users who issue various requests on a network, while maintaining the real-time nature of the apparatus. The image processing apparatus includes a developing unit for developing image data to time-varying image data, an image processing unit for performing image processing of the time-varying image data, a network interface for sending out the time-varying image data processed by the image processing unit onto a network, and a network control unit for controlling the time-varying image data for which multiple different image processing operations have been performed by the image processing unit, to be outputted to the network interface within one picture period.
