Captured image display device, captured image display method, and captured image display program

A captured image displaying device adapted to generate a video signal for causing a thumbnail image of a video taken by an imaging device to be displayed on a map, the device comprising:

• a synthesis unit that generates a video signal for synthesizing and displaying a thumbnail image of a video of an imaging device in an image display area provided in association with an imaging position of the imaging device on a map, wherein
• when there are imaging positions of a plurality of imaging devices in the image display area, the synthesis unit generates a video signal that causes thumbnail images of videos of the plurality of imaging devices to be displayed in the image display area according to a predetermined order so as to overlap each other.

A captured image displaying method adapted to generate a video signal for causing a thumbnail image of a video taken by an imaging device to be displayed on a map, the method comprising:

• generating a video signal for synthesizing and displaying a thumbnail image of a video of an imaging device in an image display area provided in association with an imaging position of the imaging device on a map, wherein
• when there are imaging positions of a plurality of imaging devices in the image display area, the generating of a video signal generates a video signal that causes thumbnail images of videos of the plurality of imaging devices to be switched and displayed in the image display area in a predetermined sequence, or generates a video signal that splits the image display area and causes the thumbnail images of the videos of the plurality of imaging devices to be displayed in split areas.

A captured image displaying program adapted to generate a video signal for causing a thumbnail image of a video taken by an imaging device to be displayed on a map, the program comprising computer-implemented modules including:

• a synthesis module that generates a video signal for synthesizing and displaying a thumbnail image of a video of an imaging device in an image display area provided in association with an imaging position of the imaging device on a map, wherein
• when there are imaging positions of a plurality of imaging devices in the image display area, the synthesis module generates a video signal that causes thumbnail images of videos of the plurality of imaging devices to be switched and displayed in the image display area in a predetermined sequence, or generates a video signal that splits the image display area and causes the thumbnail images of the videos of the plurality of imaging devices to be displayed in split areas.
