| 20090268591 | HIGH-FREQUENCY SUPERIMPOSING METHOD AND OPTICAL DISK APPARATUS USING IT - An optical disk drive includes drive current generation unit for supplying a mark forming semiconductor laser drive current and a space forming semiconductor laser drive current; first high-frequency superimposition unit for superimposing a high-frequency component on the space forming semiconductor laser drive current; and high-frequency superimposition control unit for controlling the first high-frequency superimposition unit to stop the superimposition of the high-frequency component for a predetermined duration prior to a timing at which to switch from the space forming semiconductor laser drive current to the mark forming semiconductor laser drive current, eliminating positional variations on the disk of the mark leading and trailing edges due to the high frequency superimposition. | 10-29-2009 |
| 20100118677 | Optical Disc Apparatus, Method of Adjusting Focus Offset for Optical Disc Apparatus, and Program for Executing Focus Offset Adjustment - In an optical disc apparatus, whether an unrecorded recording layer without information recorded thereon is included in the multiple recording layers of the optical disc mounted inside the apparatus is judged. then when the unrecorded recording layer is judged to be present, a signal for focus offset adjustment is recorded in a non-user data recording area of the unrecorded recording layer, and reproduction of the recorded focus offset adjusting signal is followed by its quality evaluation, which is further followed by calculation and setup of an appropriate focus offset value based on evaluation results. | 05-13-2010 |
| 20110096641 | OPTICAL DISC, OPTICAL DISC RECORDING/PLAYBACK APPARATUS, AND INFORMATION RECORDING/PLAYBACK METHOD - For a disc on which recording is to be performed at a plurality of recording densities, a technique for easily reading out disc management information without an error is disclosed. An optical disc ( | 04-28-2011 |
| 20110235487 | RECORDING QUALITY EVALUATION METHOD OF OPTICAL DISK AND OPTICAL DISK STORAGE SYSTEM - There is provided a method of calculating the degradation over time of the quality of data recorded on an optical disk in a short time. In the method, when user data is recorded on a data area, a test signal including a component in which the signal level is smaller than a reference value, is recorded on a test area. Then, the test signal is reproduced from the test area when a predetermined time has passed, to calculate the quality degradation of the user data from the evaluation result. Alternatively, every time when the user data is recorded/reproduced on/from the data area, the test signal is recorded/reproduced repeatedly on/from the test area. Then, the test signal is reproduced from the test area at a predetermined timing, to calculate the quality degradation of the user data from the evaluation result. | 09-29-2011 |

| 20080277585 | MONITORING APPARATUS - An imaging apparatus includes a camera unit, a panorama-image generating section generating a panorama image of the entire area by combining a plurality of unit images obtained by the camera unit, a panorama-image storage/management section storing and managing the panorama image generated by the panorama-image generating section, an infrared camera photographing an object that has a temperature falling within a preset temperature range as an infrared image, a direction controller sequentially shifting the photographing direction of the infrared camera within the area being photographed, an infrared-image generating section combining a plurality of infrared images provided by the infrared camera, an image-synthesizing section synthesizing the panorama image generated by the panorama-image generating section, with the panorama infrared image generated by the infrared-image generating section, and a display displaying the synthesized image generated by the image-synthesizing section. | 11-13-2008 |
| 20090066791 | Monitoring system - Disclosed herein is a monitoring system, including an infrared camera; an image pickup direction control section configured to vary the image pickup direction of the infrared camera; a correction section configured to correct irregularity in brightness of a screen image of image data picked up in each of the image pickup directions by the infrared camera and output the corrected image data whose irregularity in brightness is corrected; an image processing section configured to connect the corrected image data corresponding to the image data picked upon in the individual image pickup directions by the infrared camera to produce a whole image; and a display section configured to display the whole image. | 03-12-2009 |
| 20090213209 | MONITORING SYSTEM FOR A PHOTOGRAPHY UNIT, MONITORING METHOD, COMPUTER PROGRAM, AND STORAGE MEDIUM - A coverage area picture imaging a maximum area is displayed on a coverage area picture display. A camera is moved within a predetermined range and a plurality of frames obtained as a result form a picture. The pixels of the picture is decimated in vertical and horizontal directions and form a thumbnail as the coverage area picture. The coverage area picture display presents a display indicating a direction in which the camera is currently directed for picture photographing. In accordance with the display, a photographing direction is controlled. A plurality of frames are photographed with respect to a designated position, then stored, and displayed. A whole picture display presents a whole panorama picture. A selective picture display presents a frame at the position designated within the whole panorama picture as a selected picture. | 08-27-2009 |
