Abstract: A rear-facing camera (17) captures a live-action video image while a front-facing camera (16) captures an image of a distributor. An avatar controller (13) controls an avatar based on the image of the distributor captured by the front-facing camera (16). A synthesizer (14) arranges the avatar in a predetermined position of a real space coordinate system and synthesizes the avatar with the live-action video image. The face of the distributor captured by the front-facing camera (16) is tracked and reflected on the avatar.

Abstract: A data replacement apparatus according to one aspect of the present invention includes an acquisition unit, a determination unit, and a replacement unit. The acquisition unit acquires first control data having a value based on the position of a first device which can be mounted on a user's head and the position of a second device which can be gripped by a user. The determination unit determines whether or not a prescribed condition is satisfied. The replacement unit replaces the first control data with second control data when it is determined that the condition is satisfied. The second control data has a value not based on the position of the first device and/or the position of the second device.

Abstract: A reaction candidate storage unit stores candidates of reactions that are switched at predetermined time intervals. A reaction candidate update control unit updates the reaction candidates stored in the reaction candidate storage unit so that a candidate of a new reaction is stored and a reaction candidate already stored is erased after a predetermined time. A reaction candidate display control unit implements control to cause a reaction candidate stored in the reaction candidate storage unit to be displayed on a display unit. A reaction posting control unit, when one of reaction candidates being displayed on the display unit is selected and instructed to be posted, implements control to post the selected reaction candidate stored in the reaction candidate storage unit.

Abstract: Since an image projected from a projector has basically not high quality due to degradation of brightness and mixture of outside light, the image shot by the conventional technology includes the projected image with basically not high quality. In order to solve the above deficiency, in an aspect of the present invention provides an image system, where live performance is provided to audience by image projection on the screen, and the image to be shot does not include the projected image with low quality. For example, the image system can later synthesize a high-quality image having the same content as the projected image.

Abstract: Conventionally, a system for real-time distribution of images of the various productions of the stage to user terminals on the network has been provided. However, it is nothing but an image, the viewer can hardly feel for participation in the performance including the production. In order to solve the above deficiency, the present invention provides a stage production system, which receives an entry of a comment for distributed live image of the stage from the user terminal on the network, promptly displays the comment in a viewable state for a viewer of the distribute live image on a display, and controls the production equipment on the real stage such as the lighting equipment, sound equipment, and smoke machine.
