Video distribution in which provided information is superimposed on video

A display control method performed by a computer for streaming-distributing a video, based on a distance image in which a streamer is captured, the display control method comprising:

• acquiring a depth distribution in the distance image;
• determining a threshold value, based on the acquired depth distribution;
• specifying, in the distance image, a distant region where depth is greater than the threshold value and a near region where depth is less than the threshold value;
• and
• providing, in conjunction with the video, to a viewer terminal to which the video is to be streaming-distributed, control information to set the distant region as a background, set the near region as a foreground, superimpose provided information over the background, and superimpose the foreground over the background over which the provided information is superimposed.

A computer-readable recording medium recording a program causing a computer for streaming-distributing a video, based on a distance image in which a streamer is captured to execute processing of:

• acquiring a depth distribution in the distance image;
• determining a threshold value, based on the acquired depth distribution;
• specifying, in the distance image, a distant region where depth is greater than the threshold value and a near region where depth is less than the threshold value;
• and
• providing, in conjunction with the video, to a viewer terminal to which the video is to be streaming-distributed, control information to set the distant region as a background, set the near region as a foreground, superimpose provided information over the background, and superimpose the foreground over the background over which the provided information is superimposed.
