摘要： 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.

摘要： The present invention relates to projection systems where one or more projectors are utilized to project a video, a still image, or combinations thereof. More particularly, the present invention relates to methods of calibrating and operating such systems. According to one embodiment of the present invention, a method of calibrating an image display system is provided. The system comprises one or more projectors oriented to project an image on a projection screen and one or more image sensors oriented to acquire an image projected on the projection screen. According to the method, the projector is operated to project a calibration image comprising one or more image fiducials on the image projection screen. The image sensor acquires the projected calibration image including the image fiducials. The respective positions of the image fiducials are identified and the identified fiducial positions are validated by applying a parametric model to compare respective ones of the identified fiducial positions with corresponding approximations of the identified fiducial positions. Corrected fiducial positions are generated when a result of one of the comparisons exceeds an error threshold. The corrected fiducial positions are used in place of fiducial positions for which errors are certified to generate geometric calibration data for the projector for operation in a calibrated projection mode. Additional embodiments are disclosed and claimed.

摘要： The present invention relates to multi-projector image rendering systems and methods for their operation. According to the present invention, a plurality of image projectors are coupled to an image processor and the system utilizes specialized image processing methodology to render an output image that is composed of pixels collectively rendered from the plural image projectors. As a result, the resolution of the rendered video can exceed the video resolution that would be available from a single projector.

摘要： The present invention relates to projection systems where multiple projectors are utilized to create respective complementary portions of a projected image. More particularly, according to one embodiment of the present invention, 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 using canonical surface data representing the image projection screen. The local parametric models 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.

摘要： The present invention relates to projection systems where multiple projectors are utilized to create respective complementary portions of a projected image. The present invention also relates to methods of calibrating and operating individual image projectors. According to one embodiment of the present invention, an attenuation map is generated for the projectors and pixel intensity values are established for the projectors by applying one or more intensity transfer functions to the attenuation maps. The intensity transfer functions are configured to at least partially account for the non-linear response of the output intensity of the projectors, as a function of an input intensity control signal applied to the projectors. Additional embodiments are disclosed and claimed.

摘要： The present invention relates to projection systems where one or more projectors are utilized to project a video, a still image, or combinations thereof. More particularly, the present invention relates to methods of calibrating and operating such systems. According to one embodiment of the present invention, a method of operating an image display system is provided. According to the method, one or more image sensors acquire respective overlapping portions I1, I2 of a projected image. Screen position coordinates for image fiducials in the first and second portions I1, I2 of the projected image are identified and used to establish first and second sets of distance metrics D1, D2 for the first and second portions of the projected image. A global point set is constructed from the first and second sets of distance metrics D1, D2. Global points within a region where the first and second portions I1, I2 of the projected image overlap are derived from only one of the first and second sets of distance metrics D1, D2. In this manner, a first subset G1 of the global point set will comprise fiducial positions derived from only one of the first and second sets of distance metrics D1, D2 and a second subset G2 of the global point set will comprise fiducial positions derived from the other of the first and second sets of distance metrics D1, D2. Alignment of the first and second subsets G1, G2 of the global point set is optimized by adjusting fiducial positions in the global point set in a manner that at least partially accounts for differences between local positional data derived from the first and second sets of distance metrics D1, D2 and global positional data of the fiducial positions in the global point set. Additional embodiments are disclosed and claimed.
