Abstract
The present invention provides a system of transmitting image data from a server via a network or another communication path to a cellular phone or another terminal. In order to enhance the picture quality of displayed images, the system causes input image data to be subjected to a tone correction process and a halftoning process according to display characteristics of the terminal. Image processing packages are provided in both the server and the terminal. The system selectively uses these image processing packages according to their processing capacities. The server determines execution or non-execution of image processing according to the type of the terminal. When any image processing is carried out in the server, a control signal representing execution of the image processing is mapped to the processed image data and transmitted to the terminal. The terminal determines requirement of further image processing in response to the control signal and carries out a required series of image processing, which has not been executed by the server. In this system, at least either one of the server and the terminal takes charge of the image processing to enhance the picture quality. Execution of the image processing by the device having the higher image processing capacity effectively improves the processing efficiency.
