a virtual cameras set in the virtual space; an event information storage unit to store information on an event which may occur during the progress of the computer game and information associating the event with the virtual camera; an event detection unit to detect that an event has occurred during the progress of the computer game; an image information acquisition unit to acquire, when an event has occurred, image information representing an image of the virtual space captured by a virtual camera associated with the event; and a gameplay recording video creation unit to create a gameplay recording video using an image acquired by the image information acquisition unit. ## Claims ### Claim 1 A gameplay recording video creation system configured to create a video of a record of playing a computer game by a player operating a character acting in a preset virtual space with an input terminal, the gameplay recording video creation system comprising: a progress control unit configured to progress a computer game by processing an action of the character input through the input terminal based on a predetermined algorithm; a plurality of virtual cameras set in the virtual space and each configured to capture the virtual space at a predetermined angle of view; an event information storage unit configured to store information on a plurality of events which may occur during progress of the computer game and information associating each of the plurality of events with one of the plurality of virtual cameras; an event detection unit configured to detect that one of the plurality of events has occurred while the computer game is in progress; an image information acquisition unit configured to acquire, when the event detection unit detects that one of the plurality of events has occurred, image information representing an image of the virtual space captured by a virtual camera associated with the event; a gameplay recording video creation unit configured to create a gameplay recording video using image information acquired by the image information acquisition unit; an evaluation information collection unit configured to collect an evaluation for image information of each event included in the gameplay recording video; and a video editing unit configured to, when the evaluation on the image information of each event does not satisfy a predetermined standard, delete the image information of the event and create a new gameplay recording video. ### Claim 2 (depends on 1) The gameplay recording video creation system according to claim 1, wherein the event information storage unit is configured to store a second event which may occur during the progress of the computer game and image information associated with the second event, the event detection unit is configured to further detect that the second event has occurred while the computer game is in progress, and the image information acquisition unit is configured to acquire image information associated with the second event from the event information storage unit when the event detection unit detects that the second event has occurred. ### Claim 3 (depends on 1) The gameplay recording video creation system according to claim 1, further comprising: an acquired image information storage unit configured to store the image information acquired by the image information acquisition unit; and a virtual camera image information storage unit configured to sequentially store image information representing images of the virtual space captured by the plurality of virtual cameras. ### Claim 4 (depends on 2) The gameplay recording video creation system according to claim 2, wherein a plurality of pieces of virtual camera and/or image information is associated with some of the plurality of events and the second event, and the gameplay recording video creation unit is configured to create a plurality of gameplay recording videos having different combinations of image information. ### Claim 5 A gameplay recording video creation system configured to create a video of a record of playing a computer game by a player operating a character acting in a preset virtual space with an input terminal, the gameplay recording video creation system comprising: a progress control unit configured to progress a computer game by processing an action of the character input through the input terminal based on a predetermined algorithm; a plurality of virtual cameras set in the virtual space and each configured to capture the virtual space at a predetermined angle of view; an event information storage unit configured to store information on a plurality of events which may occur during progress of the computer game and information associating each of the plurality of events with one of the plurality of virtual cameras; an event detection unit configured to detect that one of the plurality of events has occurred while the computer game is in progress; an image information acquisition unit configured to acquire, when the event detection unit detects that one of the plurality of events has occurred, image information representing an image of the virtual space captured by a virtual camera associated with the event; and a gameplay recording video creation unit configured to create a gameplay recording video using image information acquired by the image information acquisition unit, wherein a plurality of pieces of virtual camera and/or image information is associated with some of the plurality of events and the second event, and the gameplay recording video creation unit is configured to create a plurality of gameplay recording videos having different combinations of image information, the gameplay recording video creation system, further comprising: an evaluation information collection unit configured to collect an evaluation for image information of each event included in each gameplay recording video, for each of the plurality of play recording videos; an evaluation information analysis unit configured to aggregate evaluations collected for each of the combinations of the event and the image information; and a video editing unit configured to create a new gameplay recording video using a combination of the event and the image information having a high aggregated result. ### Claim 6 (depends on 1) The gameplay recording video creation system according to claim 1, wherein the plurality of virtual cameras are associated with one of the plurality of events, and the image information acquisition unit is configured to acquire images of the virtual space captured by the plurality of virtual cameras associated with the event concerned. ### Claim 7 (depends on 1) The gameplay recording video creation system according to claim 1, wherein at least one of the plurality of virtual cameras is associated with a plurality of events. ### Claim 8 (depends on 1) The gameplay recording video creation system according to claim 1, wherein the one of the plurality of virtual cameras is arranged to catch a predetermined target related to the event concerned. ### Claim 9 (depends on 1) The gameplay recording video creation system according to claim 1, wherein the image information representing the image of the virtual space captured by the virtual camera associated with the event is associated with position information and posture information of the character.
