1. An imaging system, comprising a video camera, the video camera comprising: a wide field of view lens; an imaging sensor operable to form a first image having a first pixel area; and an interface operable to receive commands from a host entertainment device; in which the video camera is operable to receive a command requesting at least one secondary image, the command identifying a second pixel area of the at least one secondary image for a 3D mapping of a portion of the first image; and the imaging system further comprises a graphics processor operable to perform the 3D mapping to generate the at least one secondary image from the first image, in which the 3D mapping transforms a section of the first image depicting a surface having a normal in a first direction to form a given one of the at least one secondary image in which the normal of that surface faces directly out of the given secondary image, and the 3D mapping includes rotating an estimated normal of the depicted surface in 3D space so that its normal substantially coincides with the normal of a 2D plane of the given secondary image.
