Apparatus and method for optimized compression of interlaced motion images

An interlaced image processing module and corresponding method facilitate improved processing of interlaced motion images. In one embodiment, the interlaced image processing module receives image data frames having interlaced first and second fields and produces a reference field and error field. The reference field corresponds to the still image content of the interlaced frame, whereas the error field corresponds to the motion content of the interlaced frame, particularly the motion between fields. Motion between fields is thus represented in the error field, without redundant representation of the still image content provided by the first field. Where there is little motion between fields, the error terms will be small so the predictor preserves the coding efficiency provided by any auto-correlation in the image. Further, the interlaced image processing method does not rely upon pixel group classification, and thus avoids classification errors, and the loss of coding efficiency from still image content in motion classified blocks. Finally, problems presented by relative motion between fields are avoided, as are local artifacts. Another embodiment transforms the interlaced fields into frame data having a high frequency field and a low frequency field.

Computer interface employing a manipulated object with absolute pose detection component and a display

A system that has a remote control, e.g., a wand, equipped with a relative motion sensor that outputs data indicative of a change in position of the wand. The system also has one or more light sources and a photodetector that detects their light and outputs data indicative of the detected light. The system uses one or more controllers to determine the absolute position of the wand based on the data output by the relative motion sensor and by the photodetector. The data enables determination of the absolute pose of the wand, which includes the absolute position of a reference point chosen on the wand and the absolute orientation of the wand. To properly express the absolute parameters of position and/or orientation of the wand a reference location is chosen with respect to which the calculations are performed. The system is coupled to a display that shows an image defined by a first and second orthogonal axes such as two axes belonging to world coordinates (Xo,Yo,Zo). The one or more controllers are configured to generate signals that are a function of the absolute position of the wand in or along a third axis for rendering the display. To simplify the mapping of a real three-dimensional environment in which the wand is operated to the cyberspace of the application that the system is running, the third axis is preferably the third Cartesian coordinate axis of world coordinates (Xo,Yo,Zo).

Position detector

A position detector is provided for detecting the relative movement of first and second members which are mounted for relative movement along a measuring path. One of the members comprises a magnetic field generator for generating a magnetic field and the other member comprises first and second conductors which are inductively coupled to said magnetic field generator. The arrangement of the first and second conductors and the magnetic field generator is such that output signals are generated in a first and second receive circuits whose position varies with the relative movement between the two members. In addition to carrying information relating to the relative position between the two members, the signals induced in the receive circuits also comprise information defining the relative orientation of the two movable members, and by suitable processing of the received signals the relative orientation of the two members can also be determined. In a preferred form of the invention, the system operates to define the relative position and orientation of the two movable members in first and second directions from which the relative orientation of the two members in a plane containing the two directions can be determined. The signals induced in the receive circuits can also be processed to give an indication of the gap between the two circuits and to provide an indication of the full relative orientation of the two members.
