Display system, display method, and recording medium recording display program

A display method for displaying a specific image on a plurality of display devices by means of a plurality of image signals output from a video output device, the display method for causing one or a plurality of processors to execute:

• dividing the specific image into a plurality of divided images according to the number of the display devices, grouping the plurality of divided images into a plurality of groups, and generating a plurality of group images;
• first image outputting of outputting, to a predetermined one of the plurality of display devices, each of the plurality of group images generated in the divided image generation;
• second image outputting of outputting a second group image to the display device on a latter stage when a first group image output from the video output device in the first image outputting and the second group image output from the display device on a former stage are input;
• extracting, from at least one of the first group image and the second group image, a plurality of the divided images to be displayed by the own display device, rearranging each of the extracted divided images in accordance with a divided display area of the own display device, and generating a synthesized image;
• and
• displaying the synthesized image generated in the synthesized image generation.

A non-transitory computer readable recording medium that records a display program that displays a specific image on a plurality of display devices by means of a plurality of image signals output from a video output device, the display program for causing one or a plurality of processors to execute:

• dividing the specific image into a plurality of divided images according to the number of the display devices, grouping the plurality of divided images into a plurality of groups, and generating a plurality of group images;
• first image outputting of outputting, to a predetermined one of the plurality of display devices, each of the plurality of group images generated in the divided image generation;
• second image outputting of outputting a second group image to the display device on a latter stage when a first group image output from the video output device in the first image outputting and the second group image output from the display device on a former stage are input;
• extracting, from at least one of the first group image and the second group image, a plurality of the divided images to be displayed by the own display device, rearranging each of the extracted divided images in accordance with a divided display area of the own display device, and generating a synthesized image;
• and
• displaying the synthesized image generated in the synthesized image generation.
