20090201415 | Display Device and Display Method - A display device includes: a display unit including a plurality of pixels each including a plurality of sub-pixels; an acquisition unit configured to acquire a numbers of sub-pixels corresponding to an amount of motion of a target image between a plurality of reference original frames; an allocating unit configured to allocate the numbers of sub-pixels acquired by the acquisition unit to an interpolated frame, in accordance with an order of the interpolated frame to be interposed between the plurality of reference original frames; and a generating unit configured to generate the interpolated frame, in accordance with the numbers of sub-pixels allocated by the allocating unit. | 08-13-2009 |
20090296820 | Signal Processing Apparatus And Projection Display Apparatus - A signal processing apparatus includes: a specification unit configured to specify, based on plural pixels forming the target block, a partial region which is a part of the target block; a search-region shifting unit configured to sequentially shift, within the reference frame a search region which is compared with the partial region; a comparing unit configured to calculate a degree of coincidence between the search region and the partial region, and to specify a coincidence region which is the search region having the highest degree of coincidence with the partial region, as the search region is shifted; and a detecting unit configured to detect the motion vector of the target block based on both positions of the partial region within the target frame ad the coincidence region within the reference frame. | 12-03-2009 |
20100165003 | Image Display Apparatus And Projection Display Apparatus - An image display apparatus includes a light source controller; an element controller; and an image analyzing unit. The light source controller controls the amount of the light to be emitted from the light source, based on the target light amount and a time constant. The image analyzing unit calculates saturation based on the signal values of the video input signals of the plurality of colors, and sets the time constant according to the saturation. | 07-01-2010 |
20100182668 | Projection Image Display Apparatus - A projection image display apparatus includes a solid light source, and a projection element configured to scan a projection plane with spot light emitted from the solid light source. The projection image display apparatus includes an element controller configured to control a scanning speed of the projection element on the basis of an image input signal; and a signal corrector configured to correct the image input signal on the basis of the scanning speed of the projection element controlled by the element controller. | 07-22-2010 |
20100245586 | PROJECTION DISPLAY APPARATUS - A camera for capturing an object that will enter a projection space is attached to the casing of a projection display apparatus. The camera is installed at the position in which, when the camera faces the projection plane, at least one of the back direction and the side direction of the casing is included within the filed of view of the camera. For example, the cameras are installed on both side edges of the casing so as to face each other. | 09-30-2010 |
20100245780 | PROJECTION DISPLAY APPARATUS - A detection unit detects an entering object that will enter at least a projection space. When an entering object has been detected by a first detection unit, a controller initiates safety processing, the safety processing being milder than safety processing that is initiated when an error has occurred in the projection display apparatus itself. For example, when an entering object has been detected, the controller controls components of the projection display apparatus so as to switch to the projection of a black image and so as to maintain the state of the projection display apparatus, excluding the switching. | 09-30-2010 |
20110032488 | Projection Display Apparatus - A projection display apparatus includes: a light source, a light valve configured to modulate light emitted from the light source, a projection unit configured to project light emitted from the light valve, on a projection surface, and a valve controller configured to initialize the light valve in response to a drive-starting command to start driving the projection display apparatus; and a light-source controller configured to make the light source start operating when the valve controller finishes initialization of the light valve. | 02-10-2011 |
20120081678 | PROJECTION DISPLAY APPARATUS AND IMAGE ADJUSTMENT METHOD - A projection display apparatus displays a test pattern image formed of at least parts of three or more line segments defining three or more intersection points. The projection display apparatus computes a positional relationship between the projection display apparatus and the projection surface, based on the three or more intersection points. The test pattern image has a distortion in an opposite direction to a direction of the lens. | 04-05-2012 |

20120140189 | Projection Display Apparatus - A projection display apparatus includes: an imager; a projection unit; an acquisition unit; a shape correction unit that performs a shape correction process for projecting a shape correction pattern image on the projection plane, calculating shape correction values from the picked-up image of the shape correction pattern image, and correcting the shape of the image projected on the projection plane, based on the shape correction values; and a coordinate calibration unit that performs an interactive calibration process for projecting a calibration pattern image on the projection plane, calculating calibration correction values from the picked-up image of the calibration pattern image, associating coordinates of the picked-up image captured by the image pick-up element and coordinates of the image projected on the projection plane with each other, based on calibration correction values. The interactive calibration process is performed after the shape correction process. | 06-07-2012 |
