Abstract: The present technology relates to an information processing apparatus, an information processing method, a program, and an information processing system that are able to appropriately superimpose content on a scene visible from within a mobile body. The information processing apparatus includes a recognition section and a display control section. The recognition section recognizes a scene visible from within the mobile body through a transparent or translucent display surface provided in the mobile body. The display control section controls display of the content on the display surface according to the recognized scene. The present technology is applicable, for example, to a system that superimposes the content on a window of a vehicle.

Abstract: An image processing device according to the present technology includes: a foreground-background classification unit configured to classify an input image into a foreground image portion which is a portion in which a subject in a foreground is captured and a background image portion which is a portion in which a subject in a background farther than the foreground image portion is captured; a foreground correction unit configured to correct the foreground image portion; and an inconsistency correction unit configured to correct an inconsistent portion caused by the correction of the foreground image portion by the foreground correction unit.

Abstract: A main processing unit in a virtual reality space provision system builds a virtual reality space online. An action evaluation unit evaluates an action of a user participating in the virtual reality space by use of an avatar. A point allocation unit allocates a point to the user to be used in the virtual reality space in accordance with the evaluation. For example, the action evaluation unit evaluates participation by a user in an event held in the virtual reality space, the behavior of the user in the event, or whether the user wins or loses a game in the event.
