20130163078 | Autostereoscopic Display Apparatus - A display device is configured so that color pixels of a plurality of colors are formed in a longitudinal stripe shape. A lenticular lens is arranged on the display device, in which a periodical direction thereof is inclined with respect to the horizontal direction of the display device. A display position adjustment unit shifts a projected image data in predetermined pixel shift amounts of the respective horizontal and vertical directions including the pixel shift amount of 0, in a unit of one pixel defined by each of the color pixels of the plurality of colors in the horizontal direction of the display device and in a unit of each of the color pixels in the vertical direction thereof. A driving unit drives the display device to display the projected image data thereon. | 06-27-2013 |
20130194398 | AUTOSTEREOSCOPIC DISPLAY APPARATUS - An autostereoscopic display apparatus includes a two-dimensional display including color subpixels arranged in horizontal and vertical directions, cylindrical lenses configured to observe the color subpixels therethrough, a temperature sensor measuring an ambient temperature of the cylindrical lenses, and a parallax image changer changing the parallax images based on the measured ambient temperature. px is a horizontal pixel pitch. py is a vertical pixel pitch. Lx is a horizontal lens pitch. θ is an inclined angle of boundaries of the cylindrical lenses to the vertical direction. Ax and Ay are relatively prime natural numbers. Ax is equal to or larger than two. Bx is a minimum natural number by which a value GF indicated in the formula (2) represents an integer value. px, py, Lx and θ satisfy relational expressions represented by the formula (1) to the formula (3). | 08-01-2013 |
20130208356 | AUTOSTEREOSCOPIC DISPLAY APPARATUS - An autostereoscopic display apparatus includes a display in which color pixels of different colors are periodically arranged in a horizontal direction and color pixels of an identical color are arranged in a vertical direction, and a plurality of cylindrical lenses placed on the display and arranged parallel to each other, through which the color pixels are magnified and observed. When a pixel pitch of the color pixels in the horizontal direction is defined as px, a lens pitch of the cylindrical lenses is defined as L, an inclined angle of boundaries of the cylindrical lenses with respect to the vertical direction is defined as θ, and m is a positive integer, px, L and θ fulfill the formula (1). | 08-15-2013 |
20130265640 | NAKED-EYE STEREOSCOPIC DISPLAY APPARATUS - A naked-eye stereoscopic display apparatus satisfies θ=arctan {(Ax·px)/(Ay·py)}, GF=Bx·Lx/px, Ay≧2 and Bx≧2, Lx=α·px+β·py·tan θ, and GH=(α·px) | 10-10-2013 |
20130278736 | NAKED-EYE STEREOSCOPIC DISPLAY APPARATUS - A plurality of pixels is arrayed on a display device. On the display device, a lenticular lens is arranged in a state where a periodic direction thereof is inclined with respect to a horizontal direction. The lenticular lens divides video data of N different viewpoints into separate viewpoint directions, presents the divided video data, and creates stereoscopic vision. In the event of assigning respective pieces of pixel data of video data composed of less than N viewpoint images to the plurality of pixels and displaying the pixel data, the drive unit lowers brightness of pixel data of viewpoint images seen to overlap each other. | 10-24-2013 |
20130293691 | NAKED-EYE STEREOSCOPIC DISPLAY APPARATUS, VIEWPOINT ADJUSTMENT METHOD, AND NAKED-EYE STEREOSCOPIC VISION-READY VIDEO DATA GENERATION METHOD - On a display device, a lenticular lens is arranged in a state where a periodic direction thereof is inclined with respect to the horizontal direction. Within a maximum predetermined viewing angle defined by two viewpoint images with the largest parallax, a viewpoint adjustment unit sets a first angular region where there is a high possibility that one or more eyes may be present when an observer observes the display device, and a second angular region where there is a low possibility that one or more eyes may be present. The viewpoint adjustment unit adjusts the viewpoints so that a parallax between adjacent viewpoint images in viewpoint images to be presented in the first angular region is reduced more than a parallax between adjacent viewpoint images in viewpoint images to be presented in the second angular region. | 11-07-2013 |
20140043394 | PRINTING APPARATUS - An embodiment of this invention is directed to a printing apparatus capable of providing an output result without a printing density difference between two surfaces in two-sided printing. In the printing apparatus, one subtank is provided for each type of ink. The nozzles of printheads that receive inks supplied from the subtank and are used for printing of the front surface of a printing sheet and printing of the back surface, respectively, are aligned to almost the same level in the vertical direction, thereby making the water head pressures match. | 02-13-2014 |
20140204144 | PRINTING APPARATUS - An object of the present invention is to provide a printing apparatus, in which a time required for printing is shortened. The printing apparatus includes a first printing unit that performs printing on a first surface of a sheet by an ink jet system; and a second printing unit that performs printing on a second surface of the sheet by the ink jet system, the second printing unit being disposed on a downstream side of the first printing unit. Moreover, the printing apparatus includes a sheet discharge sensor that detects the sheet to be discharged from the second printing unit. The sheet discharge sensor includes an arm having a rotating member supported thereon, the rotating member being brought into contact with the sheet being conveyed while being rotated. | 07-24-2014 |
