20080284839 | Light Shielding Member, A Line Head and An Image Forming Apparatus Using The Line Head - A line head, includes: a head substrate that includes a plurality of light emitting element groups as groups of light emitting elements; a lens array that includes a plurality of lenses each of which faces the corresponding light emitting element group in a first direction; and a light shielding member that is disposed between the head substrate and the lens array and includes a plurality of light shielding plates which are arranged side by side in the first direction while defining a space layer therebetween, wherein each of the plurality of light shielding plates is provided with a plurality of light guide holes penetrating in the first direction and facing the plurality of light emitting element groups in the first direction respectively, the plurality of light guide holes facing each of the light emitting element groups are arranged in the first direction respectively to form a plurality of light guide portions, and lights from the plurality of light emitting element groups are incident on the plurality of lenses through the plurality of light guide portions respectively. | 2008-11-20 |
20080284840 | Method, System and Apparatus for Voice and Data Transmission Over A Conductive Path - A system that provides video signal communication between a source of video signals and a plurality of units that include destinations of the video signals, the system including an interface coupled to the source and to conductive paths, each of which serves at least one of the units and carries voice signals to and from one or more telephone devices at said unit. The interface receives video signals from the source, and also receives voice signals. The interface transmits voice and video signals onto the conductive path. Receivers at each destination of information connected to the conductive path recover the video signal and apply it to one or more of the destinations at the unit. The receivers also recover the voice signal from the telephone line and apply it to a telephone device. Signals also transmit in the reverse direction, from the units back to the interface and the source of information. | 2008-11-20 |
20080284841 | Methods, media, and devices for providing visual resources of video conference participants - Methods, media, and devices for providing visual resources of video conference participants are provided. In some embodiments, methods for providing a visual resource of a participant to a video conference comprise: determining that the participant is joining or departing the video conference; accessing a visual resource that identifies the participant; and presenting the visual resource to at least one other participant to the video conference. | 2008-11-20 |
20080284842 | STEREO VIDEO SHOOTING AND VIEWING DEVICE - A stereo video shooting and viewing device includes: a body, having two groups of eyepieces spaced apart from each other by a certain distance corresponding to a distance between two human eyes; two micro display screens, disposed on front ends of the eyepieces; two digital camera lenses, disposed on an outer side of the body, spaced apart from each other by a certain distance corresponding to the distance between two human eyes, and used for synchronously capturing images with a visual angle difference corresponding to that of the human eyes; and a main control unit (MCU), connected to the two micro display screens and the two digital camera lenses, and used for processing the images synchronously captured by the two digital camera lenses and image signals received from exterior, and displaying the images on the two micro display screens separately. In this embodiment, the images with the visual angle difference corresponding to that of the human eyes captured by the camera lenses are separately displayed on the micro display screens, so as to form a stereo image once being viewed by human eyes, thereby having the advantages of simple structure and vivid stereoscopic effects. | 2008-11-20 |
20080284843 | Three-dimensional image display method and apparatus - A three-dimensional image display method, includes: displaying a three-dimensional image including a left eye image signal and a right eye image signal displayed at a display focus angle; determining whether to change a viewing focus angle with respect to the display focus angle; calculating a pixel distance between the left eye image signal and the right eye image signal if it is determined to change the viewing focus angle; and displaying indicator marks at positions spaced as much as a half of the pixel distance from a center of a screen in leftward and rightward directions. | 2008-11-20 |
