The capture section 105 captures the screen data stored in the display plane section 104 to output to the image compression section 106. By this means, it is possible to capture only the original image data, and to omit redundant information. Thus, the original image data and setting data is divided, it is thereby possible to compress the original image data, and it is possible to perform efficient transmission/reception. The image compression section 106 compresses the image data received from the capture section 105, and outputs the data to the screen data managing section 113. The screen data managing section 113 outputs to the communication section 114 the captured original image data, transmission-side user setting information, transmission-side image quality information, and transmission-side panel information as the screen data.

Described next is the flow of screen data transmission processing and reception processing in the screen data transmitting terminal 100 and screen data receiving terminal 200.
First, the capture section 105 in the screen data transmitting terminal 100 captures original image data sent to the display plane section 104 from the image generating section 103 (step S1). Next, the screen data managing section 113 acquires the transmission-side user setting information from the user setting information managing section 108 (step S2), and outputs the transmission-side user setting information to the communication section 114. The screen data managing section 113 acquires the transmission-side image quality information from the image quality information managing section 109, and outputs the transmission-side image quality information to the communication section 114 (step S3). Then, the screen data managing section 113 acquires the transmission-side panel information from the panel information managing section 111 to output to the communication section 114 (step S4).

The screen data receiving terminal 200 sends the image data to the display plane section 203 based on the received screen data (step S6), and further sends the transmission-side user setting information to the user setting information managing section 206 (step S7). Then, based on the received screen data, the transmission-side image-quality setting information is output to the image quality information managing section 207 (step S8), and the transmission-side panel setting information is output to the panel information managing section 208 (step S9). Next, based on the information in the image tone reflecting section 204 and panel information managing section 208, the terminal 200 displays the reproduced screen in the display section 209 (step S10).
By executing the above-mentioned flow whenever a display frame of the screen data transmitting terminal 100 is updated, the screen data receiving terminal 200 is capable of reproducing the same screen display as in the screen data transmitting terminal 100.
A screen display example will be described below.
Meanwhile, the screen data receiving terminal 200 receives the screen data, and reproduces the screen in the display section 209.
In the above-mentioned Embodiment, the screen data transmitting terminal 100 transmits to the screen data receiving terminal 200 the captured original image data, transmission-side user setting information, transmission-side image quality information and transmission-side panel information as the screen data, and another constitution may be performed such that the captured original image data and transmission-side user setting information is transmitted as the screen data without transmitting the transmission-side image quality information and transmission-side panel in formation. By this means, it is possible to reproduce the screen displayed in the transmission-side terminal in the reception-side terminal without undergoing effects of unnecessary information such as the panel state, etc. As a result, it is possible to reproduce the same screen and to find an error in user setting.
When the apparatuses of the same configuration are used in the screen data transmitting terminal 100 and screen data receiving terminal 200, the screen data transmitting terminal 100 transmits the captured original image and transmission-side user setting information to the screen data receiving terminal 200, and by changing the reception-side user setting information, the same screen display is actualized in the screen data transmitting terminal 100 and screen data receiving terminal 200. Further, when different models are used in the screen data transmitting terminal 100 and screen data receiving terminal 200, by using the above-mentioned method, it is possible to confirm an obvious error (such as reddish screen display, etc.) in the transmission-side user setting information in the screen data transmitting terminal 100.
Described next is the flow of processing in the screen data transmitting terminal 100 and screen data receiving terminal 200 according to Embodiment 2.
First, the capture section 105 in the screen data transmitting terminal 100 captures image data sent to the display plane section 104 from the image generating section 103 (step T1). Next, the screen data managing section 113 acquires the transmission-side user setting information from the user setting information managing section 108 (step T2) to output to the communication section 114. The communication section 114 transmits the captured original image data and user setting information as the screen data to the communication section 201 in the screen data receiving terminal 200, and the communication section 201 acquires the screen data (step T3).
The image generating section 202 outputs the captured original image data to the display plane section 203 based on the screen data captured through the communication section 201 (step T4) to store the image data in the display plane section 203. Next, the image generating section 202 outputs the transmission-side user setting information to the user setting information managing section 206 (step T5). Then, the screen data receiving terminal 200 displays the screen displayed in the screen data transmitting terminal 100 (step T6). By this means, it is possible to reproduce the same screen as the screen on the transmission side and to find an obvious error in user setting, etc.
In addition, the Embodiments disclosed in the forgoing are illustrative, and the invention is not limited to the scope of the Embodiments. In the above-mentioned example, the screen data transmitting terminal 100 transmits the capture screen data to the screen data receiving terminal 200 on a frame-by-frame basis, but in the case where a change amount is small in the captured original image data, the terminal 100 may transmit the data only when the captured original image data changes so as to save the communication band. Further, the screen setting information may be transmitted only when the information changes.
