Abstract: A method of calibrating an endoscope including the steps of placing a calibration target in front of the endoscope, capturing an image frame of the calibration target by the endoscope, determining a pixel value for each pixel of the image frame, comparing each pixel value with a reference value and determining a compensation value for each pixel.

Abstract: An image conversion system for converting monoscopic images for viewing in three dimensions including: an input means adapted to receive the monoscopic images; a preliminary analysis means to determine if there is any continuity between a first image and a second image of the monoscopic image sequence; a secondary analysis means for receiving monoscopic images which have a continuity, and analyzing the images to determine the speed and direction of motion, and the depth, size and position of objects; a first processing means for processing the monoscopic images based on data received from the preliminary analysis means or the secondary analysis means; a second processing means capable of further processing images received from the first processing means; a transmission means capable of transferring the processed images to a stereoscopic display system.

Abstract: A method of producing left and right eye images for a stereoscopic display from an original 2D image including the steps of: a) identifying at least one object within said original image, b) outlining said or each object, c) defining a depth characteristic for said or each object, d) respectively displacing selected areas of said or each image by a determined amount in a lateral direction as a function of the depth characteristic of said or each object, to form two stretched images for viewing by the left and right eyes of the viewer.

Abstract: A system for displaying a plurality of images to multiple viewers (V1, V2, V3, . . . , VN) includes at least one semi-reflective mirror (12), a retroreflective screen (15) and a plurality of optical imaging means (not shown), each viewer being provided with a respective optical imaging means, each optical imaging means including a projection means for projecting images along an optical path, a tracking means (not shown) to determine the spatial position of the respective viewer's eyes, and a focusing means (not shown) to modify the optical path in response to movement of the respective viewer (V1, V2, V3, . . . , VN).

Abstract: A tracking system is provided for locating the eyes of a viewer including: an illumination element; a plurality of cameras; and a processor; wherein at least the viewer's eyes are illuminated by the illumination element to enable capture by each camera, and wherein the processor is adapted to process images from each camera so as to detect the position of the viewer's eyes.
