| 20090201431 | PROJECTOR, MULTI-SCREEN SYSTEM, PROJECTOR CONTROL METHOD, COMPUTER PROGRAM PRODUCT, AND INFORMATION STORAGE MEDIUM - A image pickup unit picks up an image of a video projected by a projection unit and outputs the picked-up image. A control unit determines whether the picked-up image includes a projection video other than the video projected by the projection unit or not. If the control unit determines that the picked-up image includes a projection video other than the video projected by the projection unit, the control unit instructs a keystone correction unit to carry out keystone correction of the video signal in accordance with the picked-up image. The keystone correction unit carries out keystone correction of the input video signal or the output video signal so that an edge of the video projected by the projection unit contacts an edge of the projection video other than the video projected by the projection unit. | 08-13-2009 |
| 20100188589 | IMAGE ADJUSTMENT DEVICE AND METHOD FOR AN IMAGE PROJECTOR IN AN AIRCRAFT - An image adjusting device and method for image projection in an aircraft, in which vibration-induced excursions between a projection device and an associated projection surface are offset via the corresponding acquisition of position-time states in such a way that an image displayed on a display surface remains essentially unchanged. | 07-29-2010 |
| 20100220247 | DIGITAL CORRECTION MODULE FOR VIDEO PROJECTOR - A geometry correction module for a fixed pixel raster projector to project an image onto a projection surface is provided. The geometry correction module includes a receiver and a geometry corrector. The receiver collects an input pixels grid that represents an input image. The geometry corrector generates an output pixels grid representing an output image that compensates for the geometry of the projection surface by repositioning image data interpolated from at least two input pixels. The output image represents an altered input image that when projected onto the projection surface will display a correctly proportioned input image. A method of correcting geometry distortion when projecting an image is also provided. | 09-02-2010 |
| 20130278840 | System And Method For Image Aspect Preservation In Multiple Projector Alignment - A method is disclosed herein that derives a post-alignment transform that is applied to the input source after the application of an alignment transform to ensure that when each source illuminates the screen, the display is aligned and retains the correct displayed aspect ratio. The transform takes into account the alignment transform and the input source aspect, and then performs a secondary, post-processing transformation that corrects the distortion induced by the alignment transform. This aspect-preserving function is a linear transform that maps pixels in the aligned space to the aligned and aspect-correct space and can be applied to the input signal after the first alignment transform, or, in the case where the alignment transform is also linear, transforms can be directly combined to derive a compound multi-projector, aspect preserving transform. In this way, the input signal to the projectors will be aligned as well as retain proper aspect. | 10-24-2013 |
| 20160091781 | INTEGRATED AND ADJUSTABLE IMAGE PROJECTION WITH AUTO-IMAGE CORRECTION IN ELECTRONIC DEVICES USING AN IN-FACING OR WORLD-FACING IMAGE PROJECTOR - A system and method for implementing integrated and adjustable image projection with auto-image correction in electronic devices using an in-facing or world-facing image projector are disclosed. A particular embodiment includes an electronic device including: a lid; a base including a hinge coupling the lid with the base; and an image projection subsystem including an image projector installed in the lid, the image projector being configured to produce a projected image that is projected onto a projection surface, the angle of the projection being adjustable by adjusting the angle of the lid relative to the base. | 03-31-2016 |
