20080218641 | Method and System for a User-Following Interface - Techniques are disclosed for projecting an image onto a surface suitable for interaction with a user while avoiding user occlusion, and while correcting for distortion due to oblique projection. The displayed image moves to a suitable surface at a suitable size and orientation as a user moves around an environment, resulting in a user-following interface. Surfaces are selected in which the projected interface is not occluded by the user or other objects in the environment. Displayed images may be interactive, and moved into an interaction area on a suitable surface that is convenient for the user. The interaction area may or may not coincide with the display area. Adaptation of the projected interface is allowed so that the content of the display and the style of interaction widgets are modified based on distance from the user and orientation of the user with respect to a projected interface. | 09-11-2008 |
20090059096 | IMAGE SIGNAL PROCESSING APPARATUS AND VIRTUAL REALITY CREATING SYSTEM - A virtual reality creating system including: a screen | 03-05-2009 |
20150009416 | DISPLAY DEVICE, IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD, AND COMPUTER PROGRAM - Provided is a display device including an image display unit configured to display an image with a plurality of pixels arranged on a display surface, an eyepiece optical unit configured to project the display surface of the image display unit in a manner that a predetermined angle of view is obtained, and an image correction unit configured to correct a display image on the display surface at a position of each of representative pixels which are discretely located on the display surface, on the basis of distortion generated due to the eyepiece optical unit. | 01-08-2015 |
20150029407 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image processing apparatus generates image data for projection by applying a deformation process to obtained image data based on an input parameter related to the deformation process. The image processing apparatus prohibits execution of the deformation process if it is determined that a magnification related to the deformation process based on the input parameter with respect to the obtained image data is out of a predetermined range. | 01-29-2015 |
20150092114 | KEYSTONE CORRECTION METHOD AND APPARATUS OF CURVED DISPLAY - A keystone correction apparatus and method of curved display are provided. The apparatus includes a curved screen that displays an image and a projector that has an infrared lighting device to irradiate infrared light to the curved screen. An infrared imaging device is configured to capture infrared light reflected from the curved screen. A controller is configured to determine whether the curved screen is distorted using an infrared image captured by the infrared imaging device and perform a keystone correction. | 04-02-2015 |
20150103257 | IMAGE PROCESSING DEVICE, PROJECTOR, AND METHOD OF CONTROLLING PROJECTOR - An image processing device used for a projector displays an image by projecting the image on a projection surface. A detection image generation section adapted to generate a detection image, which is an image adapted to detect a state of a projection image displayed on the projection surface, and includes a plurality of detection image parts is provided. Each of the detection image parts includes a plurality of regions having respective luminance values different from each other. The detection image generation section changes the luminance distribution of each of the detection image parts of the detection image to be generated so that the maximum luminance values of the detection image parts included in the taken detection image obtained by taking the detection image projected on the projection surface fall within an allowable range. | 04-16-2015 |
20160127704 | DISPLAY CONTROL APPARATUS, METHOD OF CONTROLLING THE SAME, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM - A display control apparatus which projects and displays at least one image on a screen, converts a frame frequency for a display of the at least one image to N times (N>1), generates an added image by adding a predetermined pattern to the converted frame and a subtracted image by subtracting the predetermined pattern from the converted frame as a first frame and a second frame following the first frame, projects the generated first frame and the second frame for an image on the screen at the N-times frequency, acquires the image projected on the screen, extracts the pattern from the acquired image, and corrects a shape of the image based on the extracted pattern. | 05-05-2016 |
20160142691 | IMAGE PROCESSING APPARATUS, IMAGE PROJECTION SYSTEM, IMAGE PROCESSING METHOD, AND COMPUTER PROGRAM PRODUCT - According to an embodiment, an image processing apparatus includes a corresponding point calculator, a parameter calculator, a corrector, and a detector. The corresponding point calculator calculates corresponding points between an input image and a captured image including a projection surface onto which a projection image is projected. The projection image is generated from the input image. The parameter calculator calculates a correction parameter based on the input image, the captured image, and the corresponding points. The corrector corrects pixel values of the input image using the correction parameter with respect to each color component. The detector detects a change in the projection surface. When the detector detects the change in the projection surface, the corresponding point calculator updates the corresponding points for the change, and the parameter calculator calculates the correction parameter based on the updated corresponding points. | 05-19-2016 |
