  • Patent number: 7715286
    Abstract: An optical pickup (20) projects a read beam onto an optical disc (40) as an optical storage medium which is driven to rotate by a spindle motor (30) and receives its reflection. A laser beam from a laser producing element (21) passes through a liquid crystal panel (25) and guided to an objective lens (26). The panel (25) is provided to correct spherical aberration caused by an irregular thickness of a transparent substrate of the optical disc (40). A control circuit (50) changes a spherical aberration correction signal SA to carry out sampling more than once, covering a range of the output of an optical sensor (31) where the output shows large changes. The circuit (50) determines the position of a peak of an approximation curve through calculation and designates that position as the magnitude of correction. Thus, the optical pickup (20) can quickly and accurately detect the magnitude of the correction of the spherical aberration caused by an irregular thickness of the optical disc (40).

  • Patent number: 7714850
    Abstract: A display device includes a left and a right panel sections provided adjacently along a sequence of a plurality of data signal lines, and a plurality of source drivers which are provided along a sequence of the data signal lines and correspond to the panel sections. A controller sends data signals to the respective source drivers in parallel, and a start signal to one of the source drivers in each of the display panel. In each panel section, an operation of acquiring data signals sequentially shifts from the source driver having received the start signal to the next source driver. The controller sends the start signals to the two source drivers closest to a border between the two display regions, and rearranges an order of data signals, which are supplied to source drivers in one of the display regions, to be in line with an order of data signals which are supplied to the other one of the display regions.

  • Patent number: 7715618
    Abstract: A controller (101) designates the method of integrating viewpoint images. An image integrator (102) creates an integrated image by placing individual viewpoint images in appropriate positions. A 3D image control information creator (103) creates 3D image control information by formatting the placement mode of individual viewpoint images and various 3-dimensional image characteristics. An encoder (104) encodes integrated image data. A multiplexer (105) multiplexes the coded data and the 3D image control information and outputs them. A filename deciding unit (106) decides the name of a file when multiplexed data is recorded as a file. A storage directory deciding unit (107) decides the directory in which a file to be recorded is stored. A file creator (108) records a file with the decided filename under the decided storage directory. Thus, the distinction between 3-dimensional display image data and 2-dimensional image data can be clarified.

  • Patent number: 7715858
    Abstract: A secondary station has a receiver capable of resolving signals received (504,510) as a plurality of multipath signals from a plurality of base stations during a soft handover process. In order to decode and act upon the received signals in a very short period of time, an initial subset of received multipath signals is processed (506) to provide an estimate of the action needing to be taken by the station, which action is then implemented by the station (508). Later arriving signals are processed separately (512) and used to update the estimate, as a result of which the action already taken may be corrected (514). Such a secondary station is particularly suitable for decoding and acting upon power control commands included in received signals in a UMTS system, for which a very limited period of time is provided by the UMTS specification.
