PROBLEM TO BE SOLVED: To drive a large-sized high definition panel merely by adding the change of an extremely small scale to an existing system. SOLUTION: An image display system is provided with a transmitter (PC) 10 for transmitting image data, based on the plotting instruction from an OS or an application and a reception side monitor 40 for displaying the image data received via a monitor cable 39 on a high-definition panel 41. The transmitter 10 is provided with a plot instruction analyzer 20 for detecting an area, where a change is generated on an image by the plotting instruction and calculating the transmission area to be transmitted, on the basis of the detected area and a graphics card 12 for transmitting a packet including the calculated transmission area, which includes the control information of the transmission area in the packet by the form of header data and transmitting it. The reception side monitor 40 is provided with a packet receiver 50, provided with a frame memory for analyzing the header data from the transmitted packet and developing the image data, on the basis of the header data.
