Video distribution system, video distribution method, and display terminal

A video distribution method performed by a video distribution system, comprising:

• acquiring a low-resolution image from a low-resolution camera while acquiring a high-resolution image from a high-resolution camera, the high-resolution image having a narrower angle of view than the low-resolution image, having a higher resolution than the low-resolution image, and representing a region of a real space included in the low-resolution image;
• determining whether or not there is an abnormality in any one of a first signal representing the low-resolution image and a second signal representing the high-resolution image;
• and
• transmitting first synthetic images to a display terminal in a case where it is determined that there is no abnormality, the first synthetic images having continuity between the low-resolution image and the high-resolution image, and transmitting second synthetic images to the display terminal in a case where it is determined that there is an abnormality, the second synthetic images substantially reproducing the continuity by replacing an image acquired from one determined to have the abnormality between the low-resolution camera and the high-resolution camera with a substitute image corresponding to the region of the real space.

A display terminal comprising:

• an image acquisition unit that acquires first synthetic images having continuity between
• a low-resolution image acquired from a low-resolution camera and
• a high-resolution image acquired from a high-resolution camera, the high-resolution image having a narrower angle of view than the low-resolution image, having a higher resolution than the low-resolution image, and representing a region of a real space included in the low-resolution image;
• and
• a display control unit that
• displays the first synthetic images on a display unit in a case where there is no abnormality in any one of a first signal representing the low-resolution image and a second signal representing the high-resolution image, and
• displays second synthetic images on the display unit in a case where there is an abnormality, the second synthetic images substantially reproducing the continuity by replacing an image acquired from one having the abnormality between the low-resolution camera and the high-resolution camera with a substitute image corresponding to the region of the real space.
