Abstract: To solve the problem with mobile phone carriers that increasing mail traffic increases storage capacity of a mail server and network load, a relay server which relays a mail transfer (SMTP communication) and a mail fetch (IMAP communication) is installed in a carrier facility network. The relay server compresses a mail including a header transferred from a mail transfer server, adds a new header to encapsulate the mail, and transmits the encapsulated mail to an IMAP server as a compressed mail. In response to a mail fetch request from a communication terminal, the relay server decapsulates and restores the compressed mail fetched from the IMAP server, and transmits the restored mail to the communication terminal. The relay server changes parameters such as the mail size, so that no inconsistency of IMAP commands occurs in compressing/restoring the mail.

Abstract: In a stereoscopic display system, comprising a display and a lens array, it is difficult to manufacture the lens array with lens spacing at high accuracy as designed, and it is also difficult to attain high installation accuracy when the display and the lens array are combined together. An image of a stereoscopic display 27 with a display 1 and a lens array 2 integrated with each other is taken by a camera 3, and a positional relation of each pixel of the display 1 and each lens center of the lens array 2 is determined by a measuring system 4. Based on the matching positional relation information of the lenses and the pixels thus acquired, a stereoscopic image generating/outputting system 12 generates a stereoscopic image and supplies the image to the stereoscopic display 27.

Abstract: The present invention represents an object with high-quality texture. A texture image display apparatus includes: a panel display device (20) having a plurality of pixels (21); a lens array (30) having a plurality of lenses for controlling outgoing directions of light outputted from the pixels (21); a pixel data generation part (14) for generating pixel data for each pixel; and a panel driving circuit 15 for driving the panel display device (20) on the basis of the pixel data. One lens (31) is provided for a plurality of adjacent pixels (21), and directs light outputted from these adjacent pixels (21) in directions different from one another. For each pixel (21), the pixel data generation part (14) generates pixel data of different image brightness levels depending on outgoing direction of light, for the same image point in displayed content.

Abstract: An autostereoscopic display includes a display having a non-luminescence area between two adjacent pixels. Each pixel includes a blue subpixel, a red subpixel, and a green subpixel. A lens sheet including a lot of lenses is configured over the display. A diffusion board is placed between the display and the lens sheet. The diffusion board has a trench disposed over the non-luminescence area between two adjacent pixels.

Abstract: In an autostereoscopic display, a horizontal view range can be widened without reducing two-dimensional resolutions. Lenses are arranged to be a linear combination having integer coefficients of two unit vectors, thereby to control the vertical and horizontal view ranges.

Abstract: Objects of the present invention are to widen a visual field of a three-dimensional image display device, and to improve the image quality of the three-dimensional image display device. A number of pixels 51, 52 are formed on a two-dimensional image display device 1 for providing image data of a three-dimensional image. A lens array 2 constituted of a large number of micro lenses 3 is disposed on the two-dimensional image display device 1. Each of the micro lenses 3 is associated with a plurality of pixels 5, each of which emits the same color. In order to ensure a visual field ? required for the three-dimensional image, a diameter LD of each of the micro lenses 3, the distance DFL between each of the pixels 5 and each of the micro lenses 3 in the two-dimensional image display device, are properly set.

Abstract: An apparatus for rendering a three-dimensional model from a plurality of eye points to present a three-dimensional picture, wherein the position of a virtual camera for rendering apexes of the three-dimensional model is controlled in accordance with the amount of protrusion of an object under rendering from a display plane to create and present a non-perspective projection picture as a picture at each eye point position. Also, for this control, a weighting parameter is incorporated in each part of the three dimensional model, such that the presentation of stereoscopic sense can be finely controlled.

Abstract: Devices that provide stereoscopic vision by placing a lens array or a pinhole array on a display have a problem. The resolution of an object in the background present at a great distance is degraded. With respect to a three-dimensional object of interest, an intermediate stereoscopic image. This intermediate image is synthesized with a two-dimensionally projected background image separately prepared to obtain another image, and this image is displayed on a stereoscopic display.

Abstract: An acceleration sensor housed in a confined space can detect rotational acceleration with great accuracy. The acceleration sensor has first and second piezoelectric elements with electrodes for outputting a charge produced by strain deformation. Each of the first and second piezoelectric elements has at least one piezoelectric body and a support block for supporting the piezoelectric body. The electrodes are provided on opposite sides of the piezoelectric body. One surface of the first piezoelectric element and one surface of the second piezoelectric element are substantially parallel to each other.
