摘要： A method of positioning an image of a subject, placed before a selected backing, to a desired position with respect to an image of a background scene appearing on a camera view screen, using a digital camera. An image is observed on the camera's view screen and at least one of the subject and the camera are physically positioned to place the subject's image at the desired position with respect to the image of said background scene. An image of the positioned subject in front of said background scene is captured in the camera. A composite image of the subject and the background scene is then formed. Additional subjects may be captured and composited using the prior composite as the background scene for each added subject.

摘要： A teleconferencing system in which the video image of a subject in front of a selected background scene is extracted from that scene and transmitted to other locations where selected backgrounds are stored. By compositing the subject and background images (25) at each remote location, both image elements, being originals, will show no loss of detail when projected. For a front projection screen (29), the projector (27) is inhibited from illuminating a presenter (28).

摘要： A method for projecting an image onto a front projection screen without the image being projected onto a presenter and without the presenter casting a shadow. Left and right rectilinear corrections of an image are simultaneously projected onto the screen from each of two positions that are off-axis on opposite sides of the centerline of the screen such that both projections register as a single image. A center of mass of the presenter's silhouette is generated. A vertical join line is located on the screen directly behind said presenter's center of mass. The portion of the projected image from the left projector that extends to the right of the join-line is inhibited. The portion of the projected image from the right projector that extends to the left of the join-line is also inhibited thereby providing the full projected image on the screen from the left and right image segments, without either segment projecting said image onto the presenter, and without casting the presenter's shadow onto the screen.

摘要： A method for extracting a clear frame from an image frame containing at least one or more subjects disposed before a backing, whose color and luminance vary smoothly from one backing area to another. The method replaces a subject's pixel signal levels with backing pixel signal levels. The method selects a known backing pixel and compares the RGB signal levels of an adjacent pixel with the RGB signal levels of the known backing pixel and identifies the adjacent pixel as a backing pixel when its RGB signal levels are each within an assigned tolerance of the RGB signal levels of the known backing pixel. This comparison is performed on all known backing pixels with unidentified adjacent pixels until all pixels in the image frame have been examined and all backing pixels identified. The method then replaces the RGB signal levels of the at least one subject's pixels with the RGB signal levels of backing pixels located at opposite edges of said at least one subjects by at least one of interpolation and or extrapolation across the at least one subject thereby removing said at least one subject to leave a clear frame.

摘要： A video signal is generated representative of a background scene, such as a weather map, which provides an outline of all the detail in the map. This outline detail is made visible to a foreground subject (2) by projecting it onto a white screen (1) behind the subject in a selected color such as green. The projector (3) is selectively inhibited so as to prevent the background detail from projecting onto the foreground subject. The white screen and the green detail lines are removed and replaced by the background scene by an image compositing process. Prompts are visible to the foreground subject, but not visible to a home viewing audience.

摘要： A pattern is projected onto a screen by a projector using an illumination having a nonvisible wavelength. A camera, displaced several inches from the projector, observes the projected pattern whose signals are then stored to create a reference frame. The pattern is then projected onto the screen a second time with a presenter present. The camera observes the projected pattern whose signals are then stored to create a current frame, including the presenter, and signals obtained from the reference frame are compared to determine their difference. In unobscured screen areas, the pattern images match. The pattern on the presenter is displaced because of the displaced camera, and no longer matches the reference pattern, thereby identifying the presenter's silhouette area.

摘要： Changes in a current image frame (Cu) from variations in room light level, and automatic camera adjustments, are determined and incorporated into a clear (reference) frame (C1), thereby resulting in a zero difference in the background region when the clear frame (C1) and a current frame (Cu) are subtracted. Any deviation from zero defines the beginning edge of a transition from background to subject. The location of the outer edge of a transition area is further refined by subtracting derivatives of the RGB signals in each frame, and by the use of a fourth color channel when available. The difference of derivitives (dcu-dcl) identifies the subject to background transition area, whose edges define the inner and outer boundary lines. Shadow areas on the backing are retained and may be transferred to the inserted background scene. Small areas on the backing having the same color and luminance as the subject are prevented from printing through the subject by a second "derivative" alpha channel for the small areas.
