Abstract: The present invention is in the field of digital imaging. It relates to a method and a system for selecting a subject of interest in a digital image, so as to be able to then display this subject of interest on the screen of a terminal with low display capacity. The present invention enables the display directly and automatically on the screen of a terminal with low display capacity, of subjects of interest, previously selected in an original image. This is done based on a simple operation or request executed from the terminal with low display capacity. This enables the image to be exploited correctly, by viewing the subjects of interest of the original image, in the best possible conditions of image rendering, given the display capacity of said terminal. The application of the present invention is in the area of the users of terminals with low display capacity.

Abstract: An image cut-away/display system is disclosed. Images are taken in continuous view areas by several cameras, etc. The images are combined for forming a single wide-area view image. View-point data is generated for each of users. Images are cut away for each user from the single wide-area view image based on the view-point data for each user. The cut-away images are displayed on a head-mount display for each user at a view point of each user.

Abstract: An image processing method converts line vectors of an input graphic path and an input clip path into run sets in dot coordinates passed by the line vectors, and generates a region run describing a closed region represented by the entire path from the run sets, so as to obtain a graphic region run and a clip region run, and extracts an overlapping portion of the graphic region run and the clip region run to generate a plot region run. The scan line conversion and the clipping form a rasterizing process.

Abstract: A client-server arrangement for camera viewing using digital cameras across a computer network. A camera server controls a motorized gimbal which determines the viewing angle of a camera, according to signals from a client computer which is equipped with an eye movement tracking system. Movements of the viewer's eyes result in changes in viewing angle of the remote cameras. The original full-resolution image is divided into a foveal area and a peripheral area. Subsequently, if a change in the peripheral area of a field of view is detected relative to the most recently displayed image, the viewing angle of the cameras is changed to center on the detected change, and an image is captured of this anticipated future field of view. When the viewer eventually changes his or her point of interest to the area of detected change, the pre-captured image is transmitted immediately for viewing.

Abstract: The present invention provides a mechanism by which the number of bits used to identify the WIDs for each of the color buffer and the overlay buffer may be programmed into the graphics adapter based on the currently active application environment. With the apparatus and method of the present invention, a programmable WAT color size selection device is provided in a RAMDAC of the graphics adapter. This programmable WAT color size selection device may be dynamically programmed to use varying bit splits of a WID from a WID buffer to obtain different indexes into a color WAT table and an overlay WAT table. In this way, different splits of, for example, an eight bit WID may be obtained based on the setting of the programmable WAT color size selection device such that varying color and overlay capabilities are obtainable dynamically.

Abstract: Embodiments of the present invention efficiently support rendering of high resolution images under zone rendering. In particular, a bin array rectangle and binner clipping rectangle for determining primitive-zone intersections. Both of these rectangles are defined by graphics device state variables containing the screen-space location of the rectangle corners. In particular, the binner clipping rectangle is used to define the visible region in screen coordinates. Objects completely outside the binner clipping rectangle in one or more directions will be discarded. Objects that cannot be trivially rejected are subjected to bin determination. The bin array rectangle handles color buffer resolutions larger than could otherwise be accommodated by the optimally-renderer image limits.

Abstract: A system and methods for creating user definable windows for applying image processing, particularly useful in a post-production color correction equipment. The system allows a user of an image processing system such as a scene by scene color corrector to define a color region of interest in an image for purposes of applying image processing only to the region of interest, with automatic tracking of that region of interest over a plurality of frames in a scene. The user defined window, comprising a closed polygon, is converted on a frame-by-frame basis to a matte that is keyed with image processing such as color correction values. The user defined windows can be edited and stored and recalled for use in other frames.

Abstract: A method and system for transferring interactive videos from a video source to a video display system is disclosed. The method and system reduces the bandwidth required between the video source and the video display system. Rather than transferring all image data from each image frame of an interactive video, only relevant portions of subsequent image frames are transferred. For example, in one embodiment of the present invention, a view window is defined in a current image frame. Then, a view neighborhood is defined for a subsequent image frame. Image data from the subsequent image frame within the view neighborhood is transferred to the video display system.

An optimum, median fused depth map of a new, desired view of an object or a scene is constructed from a plurality of depth maps of the object or scene, utilizing median values for each of the image pixels within the image domain of the new view.

The calculated median values are then assembled into a median fused depth map of the new view of the object or scene, with the median fused depth map available to construct a new two or three dimension images and models of the object or scene as perceived from the new view.

Abstract: A method and apparatus used to render cubic curves is disclosed. A cubic Bezier curve is rapidly decomposed into small segments piecewise by using two independent operation units in parallel for processing four control points of the cubic Beizer curve with the assistance of an arbitrator to display the cubic curve on a monitor or output to a printer. A set of control data of the cubic Beizer curve is obtained from an input device and serves as the original input data for a vertical division operation unit and a horizontal extension operation unit that generate four sets of control points in parallel. The arbitrator makes two decisions from the four sets of control points. First, if there are sets of control points meeting the condition of rendering the curve, those sets are transferred to a segment generator to generate points for rendering the curve. Second, it determines which set of control points is the next feedback input data for the parallel horizontal extension operation.

Abstract: A method of de-interlacing used to convert an interlaced video signal to a progressively scanned format utilizing vertical temporal filtering to generate the missing lines, utilizing appropriate filter coefficients to give a desired vertical frequency response, and filter utilizing coefficients such that the total combined contribution from all fields is unity while the total contribution from each individual field is chosen so as to boost higher temporal frequencies which has the perceived effect of increasing the sharpness of moving edges. Furthermore, in order to avoid certain unwanted artifacts, the lines of the current field are modified using a vertical temporal filter with similar temporal boosting properties to that which was used to generate the missing lines.
