PURPOSE:To enable training in many kinds of environment by providing a video signal processing part which selecting each specific number of picture elements of digital data regarding a playback video signal and partial video signals respectively and putting them together, and outputs their composite video signal. CONSTITUTION:A video reproducing device 10 reproduces a visual field image of a driver in a train travel as the playback video signal and partial video generation parts 201 - 20n generate the partial video signals under specific playback conditions. The video signal processing part 22 selects each specific number of picture elements of digital data regarding the playback video signal partial video signals respectively and puts them together to output the composite video signal. A video display device 16 displays an image based upon the composite video signal. The composite video signal can, therefore, be generated without decreasing the SN ratio nor the resolution and the composite image is offered as the simulation visual field. Consequently, training becomes possible in many kinds of environment. |
