Abstract: A method for processing a three-dimensional (3D) graphic object, having the first step of converting a set of vertices for the 3D graphics object. Further, decomposing the 3D graphics object into a set of segments; and for each segment: (1) extracting a set of vertex coordinates; and (2) subtracting the set of vertex coordinates from a previously determined set of vertex coordinates to produce a set of encoded vertex coordinates. Then, compressing the set of encoded vertex coordinates. An apparatus for performing the method.

Abstract: An imaging system using a color shutter receives signals indicative of color information in a plurality of planes together with infrared information and a signal indicative of the infrared radiation alone. The infrared radiation signal may be subtracted from the signals associated with the color planes to develop signals free of infrared radiation effects for each of the desired color planes. In addition an infrared signal is available which may have useful applications in some situations. In this way, color information color bands may be obtained without the need an infrared filter and infrared information is retained for use in other applications if desired. In addition infrared and dark current information may be derived that can be used for dark current correction.

Abstract: A infrared pixel sensor comprising a pixel circuit and a composite infrared pass filter comprising a plurality of filters, wherein each filter belonging to the plurality of filters are substantially transparent to infrared radiation and have a visible pass spectrum so that the composite infrared pass filter is substantially opaque to visible light. Signals from infrared pixel sensors are subtracted from color pixel sensors to correct for infrared radiation in the image signal without the need for an infrared blocking filter.

Abstract: The present invention is directed to a method and apparatus for providing three-dimensional (3-D) input data to a computer. A marker is moved in a 3-D work place. The marker has at least one unique feature distinctive from other objects in the 3-D work place. The movement of the marker in the 3-D work place is sensed by at least two sensors in a stereo imaging geometry to produce stereo images containing the marker. The stereo images are processed to produce marker images. The 3-D coordinates of the marker are computed from the marker images to provide the 3-D input data to the computer.

Abstract: A method and apparatus for extracting three-dimensional (3-D) data from a target object is disclosed. A plurality of markers are formed on the object. A plurality of images are captured of the object. A first point is designated from a marker from one of the images and a line equation corresponding to the first point is determined. A second point in a marker in another image corresponding to the first point is determined and a second line equation corresponding to the second point is determined. The intersection of the two line equations is determined.

Abstract: A focal plane processor, located on the focal plane of an imaging array, allows on-chip imaging and scaling. Computational functions normally achieved by a separate computer may be achieved through the imaging chip itself. This can result in an imager with advanced functionality. Also, additional processing bandwidth provided by the focal plane processor may assist a computer which may receive different image segments from different pixel arrays each having associated focal plane processors.
