摘要： A method of displaying an image with a display system includes receiving image data for the image. The method includes generating a first sub-frame and a second sub-frame corresponding to the image data based on a geometric relationship between a hypothetical reference projector and each of a first and a second projector. The method includes projecting the first sub-frame with the first projector onto a target surface. The method includes projecting the second sub-frame with the second projector onto the target surface, wherein the first and the second sub-frames at least partially overlap on the target surface.

摘要： A method for tone mapping a digital image comprised of a plurality of high bit depth intensity values in linear space is disclosed. First, a plurality of liner intensity values are mapped from the linear space to a non-linear space (402). Then a left and a right boundary interval value are determined in the linear space for each of the plurality of high bit depth intensity value (404). A dither pattern is then overlaid onto the plurality of high bit depth intensity values in linear space (406). For each one of the plurality of high bit depth intensity values in linear space, one of the boundary interval values is selected, based on the current high bit depth intensity value, the left and right boundary interval values for the current pixel, and the dither pattern value overlaid onto the current pixel (408). Each of the selected boundary interval values are mapped into a lower bit depth non-linear space (410). And then the mapped selected boundary interval values are stored onto a computer readable medium.

摘要： A method for compensating for cross-talk in a 3-D projector-camera system having a controller including a processor and system memory and at least two channels, includes the steps of calibrating the projector-camera system, computing cross-talk factors applicable to the projector-camera system, and correcting new image data for cross-talk based upon the computed cross-talk factors. The system is calibrated by sequentially projecting and capturing, with a camera, a calibration image for each channel, to capture cross-talk between the channels. The controller can compute the cross-talk factors based upon the captured calibration images.
