| 20100259602 | HYBRID SYSTEM FOR MULTI-PROJECTOR GEOMETRY CALIBRATION - A method of calibrating a multi-projector image display system is provided. According to the method, non-parametric calibration data for the display system is recovered and used to generate a non-parametric model of the display system. Local parametric models relating to the display surface of the projection screen are generated and are compared with data points defined by the non-parametric calibration data to identify one or more local errors in the non-parametric calibration data. The local errors in the non-parametric calibration data are converted to data points defined at least in part by the local parametric models and the projectors are operated to project an image on the image projection screen by utilizing a hybrid calibration model comprising data points taken from the non-parametric model and data points taken from one or more local parametric models. Additional embodiments are disclosed and claimed. | 10-14-2010 |
| 20090284555 | SYSTEMS AND METHODS FOR GENERATING IMAGES USING RADIOMETRIC RESPONSE CHARACTERIZATIONS - Particular embodiments relate generally to display systems and, more particularly, to display systems and methods for blending multiple images. A display system may include a first display source configured to generate a first image comprising illuminated points on a display surface, and a measurement device configured to measure an output energy value of the first image at output wavelengths for input values provided to the first display source. A normalized response function of the first display source corresponding to the measured output energy values for each output wavelength may be generated. A first response function that includes one or more of the normalized response functions of the first display source may be generated to derive corrected image input values corresponding to a desired output energy value at one or more illuminated points. The first display source may be controlled by applying the corrected input values. | 11-19-2009 |
| 20090262260 | MULTIPLE-DISPLAY SYSTEMS AND METHODS OF GENERATING MULTIPLE-DISPLAY IMAGES - A display system includes a first and second display source configured to generate first and second images that overlap to form a multiple-display image. Each illuminated point within an overlap region includes a first image pixel contribution generated by the first display source and a second image pixel contribution generated by the second display source. The display system is programmed to select one or more dithering pixels within the overlap region and apply a blending function that alters one or more radiometric parameters of pixels within the overlap region. The blending function includes a deterministic blending function that alters contribution of non-dithering pixels based at least in part on the location of the non-dithering pixel within the overlap region. The blending function also includes a dithering component that alters contributions of dithering pixels within the overlap region of multiple-display image based at least in part on a modification value X. | 10-22-2009 |
