    摘要: A rear projection imaging system with an image warping distortion correction system using a camera and processing unit to generate a warping map that corrects for image distortion. The warping map is generated in an iterative process by displaying a known pattern on a viewing screen and, through the use of a camera, having a microprocessor determine the location and shape of the pattern on the screen. The microprocessor then compares the displayed image to the original reference image, calculates the distortion effects present in the projection optics, and generates a warping map.

    摘要: A television leveling module determines, using at least one accelerometer module in response to activation of the television leveling module, an angle of orientation relative to horizontal of a television coupled to a horizontal level-adjustable mounting assembly. An indication of the angle of orientation relative to horizontal is displayed on a television display. The display of the indication of the angle of orientation relative to horizontal of the television is iteratively updated in response to detected adjustments of the angle of orientation. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

    摘要: A calibration image including dots and scale points is projected at first and second display surfaces. A location of a scale point may be modified. A location for a registration point is determined and the registration point is added to the calibration image. The projected calibration image is captured. A location of the captured registration point and locations captured scale points are identified. Captured dots that are projected onto the first display surface and their locations are identified. Each of the captured dots identified as being projected onto the first display surface are mapped to a corresponding dot of the calibration image. Dots of the calibration image that are not projected onto the first display surface are identified, locations of each of the identified dots are determined, and a synthetic dot is added to the captured image for each identified dot. The captured image may be provided as input to a process for determining one or more inverse offsets.

    摘要: A depth camera and an optional visual camera are used in conjunction with a computing device and projector to display a presentation and automatically correct the geometry of the projected presentation. Interaction with the presentation (switching slides, pointing, etc.) is achieved by utilizing gesture recognition/human tracking based on the output of the depth camera and (optionally) the visual camera. Additionally, the output of the depth camera and/or visual camera can be used to detect occlusions between the projector and the screen (or other target area) in order to adjust the presentation to not project on the occlusion and, optionally, reorganize the presentation to avoid the occlusion.

    摘要: In a projection type image display apparatus, for enlarging an image on a image display apparatus 1 by means of a projection lens 2, thereby projecting the enlarged image onto a screen 6, obliquely, being inclined thereto, between the projection lens 2 and a rear-surface mirror 5, there are disposed free shaped surface mirrors 3 and 4, each having a free shaped surface for compensating a trapezoidal distortion due to oblique projection of the enlarged image. The surface configuration of the free shaped surface mirror is so shaped as to satisfy a following equation: |L1−L2|>1.4·Dv if assuming that a distance for a light beam of an upper end of the enlarged image to reach the screen after being reflected upon a free shaped surface is “L1”, a distance for a light beam of a lower end of the enlarged image to reach the screen after being reflected upon the free shaped surface is “L2”, and a distance from an upper end of an image on the screen to a lower end thereof is “Dv”.
