The invention, exemplified as a single lens stereo optics design with a stepped mirror system for tracking the eye, isolates landmark features in the separate images, locates the pupil in the eye, matches landmarks to a template centered on the pupil, mathematically traces refracted rays back from the matched image points through the cornea to the inner structure, and locates these structures from the intersection of the rays for the separate stereo views. Having located in this way structures of the eye in the coordinate system of the optical unit, the invention computes the optical axes and from that the line of sight and the torsion roll in vision. Along with providing a wider field of view, this invention has an additional advantage since the stereo images tend to be offset from each other and for this reason the reconstructed pupil is more accurately aligned and centered.

A method of processing a digital image comprising: using a digital camera, capturing the image utilising an adjustable focusing technique; storing the focusing settings within a memory of the digital camera; utilising the focusing settings as an indicator of the position of structures within the image; processing the image within a processor of the camera utilising the said focus settings to produce a manipulated image having effects specific to said focus settings; and printing out the image using a printer inbuilt to the camera body.

A multi-function display controller that includes a source detector unit for determining if the source of an input stream is either film originated source originated or video source originated. A source converter unit for converting the input image stream to a common signal processing format is coupled to the source detector unit. Once converted to the common signal processing format, a determination is made if the input image stream is interlaced or non-interlaced (progressive scan). If the input image stream is interlaced, a de-interlace unit converts the interlaced signal to progressive scan using either motion adaptive or motion compensated de-interlacing techniques. It should be noted that in the described embodiment, motion vectors generated for use by the motion compensated de-interlace can be optionally stored in a memory unit for use in subsequent operations, such as motion compensated frame rate conversion or noise reduction (if any).

An X-ray imaging control apparatus acquires radiographic data obtained from an X-ray imaging apparatus which controls an X-ray dose upon X-ray imaging by detecting the X-ray dose in one or a plurality of detection regions, and displays a radiographic image on the basis of the acquired radiographic data. At this time, detection region information indicating the position and range of each detection region used in the X-ray imaging apparatus upon generating the radiographic data is acquired. Based on this detection region information, an image indicating each detection region is superimposed on the displayed radiographic image.
