Publication number: 20090213209Abstract: 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.Type: ApplicationFiled: March 5, 2009Publication date: August 27, 2009Inventors: Hiroyuki HASEGAWA, Hideki HAMA, Hiroshi NEDU, Takeyoshi KUROYA, Masaaki KUREBAYASHI

Publication number: 20080037395Abstract: Recording parameters are decided so that the time control information on at least the front edge and the rear edge of a parameter forming a mark of twice size or above of the laser spot diameter focused on the recording medium is substantially proportional to the recording linear velocity. The mark is recorded and reproduced at a predetermined linear velocity to obtain an electric signal waveform having a time width Tm. A parameter is decided so as to control the laser pulse for recording information so that a voltage value change amount at two points at a distance Ts (Ts<Tm/2) in the time axis direction before and after the time position Tm/2 from the front edge of the waveform is substantially constant for the recording linear velocity change.

Patent number: 7274643Abstract: It is an object of the present invention to provide an information recording and reproducing technique capable of improving the reliability of information recorded on a recording medium. A recording condition comprising amplitude information and the ratio of the amplitude to the recording power is previously recorded on the recording medium. Using this previously recorded information, information is recorded and then immediately reproduced to calculate the optimum recording power from the amplitude information obtained from the reproduced signal. By adapting the recording condition accordingly, it is possible to secure reliability of information in performance.Type: GrantFiled: August 15, 2003Date of Patent: September 25, 2007Assignees: Hitachi, Ltd., Hitachi-LG Data Storage, Inc.Inventors: Tsuyoshi Toda, Hiroyuki Minemura, Masaaki Kurebayashi

Patent number: 7221401Abstract: A camera includes a lens unit and an imaging unit. The optical axis of the camera is defined as a reference line, and a central line of a shooting area including an object to be shot is defined as an imaging centerline. A shift lens is moved to a shift-lens position which corresponds to the count of pulses supplied to a servomotor of a pan/tilter, so that an object image travels along an optical path generated by the shift lens is incident on another lens, and is then incident on the imaging unit. Accordingly, the object image incident on the imaging unit does not change while the shift lens is moved.Type: GrantFiled: May 14, 2003Date of Patent: May 22, 2007Assignee: Sony CorporationInventors: Hideki Hama, Noriyuki Yamashita, Masaaki Kurebayashi
