Abstract: The rendering control unit controls the laser light source unit in such a way that a display image is rendered in a range smaller than a scan range of the scan mirror unit based on input display image data. The detection unit detects a range to be a reference for setting a laser beam output position for adjusting an output of the laser beams based on the display image data. The output adjusting control unit controls the laser light source unit in such a way that the laser beams for adjusting an output of the laser beams are output at a position outside the range where the display image is rendered in the scan range of the scan mirror unit, and the position is based on the range detected by the detecting unit.

Abstract: An image display device according to the exemplary embodiment includes: an RGB laser diode that outputs a light beam; a laser driver that drives the RGB laser diode based on input image data; a scanning mirror that scans the light beam by reflecting the light beam at an angle according to a drive voltage; and a scanner control unit that applies a bias voltage to the scanning mirror based on an angle with respect to a horizontal plane, or a static angle of the scanning mirror that is at a standstill when the drive voltage is not applied.

Abstract: A communication controller transmits current location information of a subject apparatus to another pre-registered apparatus, and receives current location information of the another pre-registered apparatus. A location relationship determiner determines whether the subject apparatus precedes the another apparatus in a heading direction. An operation mode determiner operates the subject apparatus as a main device when it is determined that the subject apparatus precedes the another apparatus in the heading direction, and operates the subject apparatus as a sub device when it is determined that the subject apparatus does not precede the another apparatus in the heading direction. A function selector activates a function of transmitting heading direction information to the another apparatus when the subject apparatus is determined to be a main device, and activates a function of receiving the heading direction information from a main device when the subject apparatus is determined to be a sub device.

Abstract: A content reproducing apparatus comprises a server monitoring means for monitoring the connection status of a server existing on a network; a content information acquiring means for acquiring information of the contents on public view at the server; and a content reproducing means for reproducing the contents on public view at the server. When detecting a server connected to a network, the content reproducing apparatus acquires information of the contents on public view at the server, and automatically reproduces the contents on public view at the server based on the acquired information of the contents. The content reproducing apparatus is provided which can reproduce the contents on public view at DMSes on a network without requiring any troublesome operations.
