ABSTRACT:
An image processing system comprising and image recording system and an image rendering system. The image recording system records images of a scene, and comprises a recording device for recording images of the scene on a series of frames, each frame including image information reflecting the scene as illuminated at the time the frame was recorded, a plurality of individually-energizable light sources each for illuminating the scene; and a synchronizer connected to the recording device and the light sources for synchronizing the separate energization of the light sources and the recording by the recording device of the separate frames in the series. The image rendering system generates a rendered image which reflects a desired light source position. The image rendering system specifically comprises a frame store for storing the image information for each of the series of frames, a rendered image store for receiving rendered image information a rendered image a rendered image information generator for generating rendered image information for storage in response to image information from the frame store related to frames of the series as recorded in synchrony with diverse ones of the light sources, the rendered image information generator generating the rendered image information in relation to the image information of each of the frames, as weighted in relation to the relationship between the position of the light sources in synchrony with which the frame was recorded and the desired position of the light source for the rendered image.
