Content addressable video system for image display
First Claim
1. A method for displaying image data representing a plurality of visual image of a subject, wherein each of the plurality of visual images comprises a different perspective of the subject, comprising the steps of:
- organizing the plurality of visual image into a matrix in which each visual image has a position in the matrix and the perspective of each visual image is indicated by its position in the matrix;
storing a frame of image data for each visual image in a location accessible in response to the position of the visual image in the matrix;
displaying a current frame;
displaying to an operator a representation of at least a portion of the matrix;
highlighting on the displayed representation, a position in the matrix of the current frame;
providing input data indicating a change in position in the matrix and thereby a desired change in perspective of the subject;
translating the input data to an updated position in the matrix;
accessing the frame having the updated position and displaying the accessed frame as a new current frame.

Abstract
An interactive video display system with tight coupling between user-input and the images displayed to provide a feeling of real control by the user. A library of frames of video data is stored in randomly accessible data locations, such as an optical video disc. The video data in each frame in the library is assigned a virtual position in a pre-defined data space, such that the visual image in each frame is related to visual images in other frames by virtual position in the data space. User input is provided through track ball or mouse generating displacement signals. The input signal is translated to an updated virtual position in the data space relative to a previous virtual position and the next frame having the updated virtual position is displayed next.
