[Object] To provide a control device that can make more efficient an inspection performed by a flying body capable of performing imaging. [Solution] Provided is a control device including an acquisition unit configured to acquire information related to an overview of a structure, and a flight information generating unit configured to generate flight information of a flying body being caused to fly over a periphery of the structure to image the structure on the basis of the information acquired by the acquisition unit. The control device generates information used to cause the flying body to image the structure, and thereby makes it possible to make more efficient the inspection performed by the flying body capable of performing imaging.

Abstract:
A method and apparatus for realizing a stable focus jump operation even in a case where a waveform of an S-curve of a focus error signal fluctuates due to aberration due to fluctuation of a multilayer optical disk substrate thickness or the level of the S-curve fluctuates due to reflectance fluctuation are provided. A focus jump processing means (DSP 51) for performing a focus jump operation moving a laser spot among recording layers of a multilayer optical disk 10 having a plurality of recording layers corresponding to a record/reproduce operation for recording data on the multilayer optical disk 10 or reproducing data recorded on the multilayer optical disk 10 performs acceleration processing for moving the objective lens mounted on an optical pick-up from a certain recording layer of the multilayer optical disk to another recording layer, waiting processing, and deceleration processing for stopping the objective lens 34 and makes an impulse of the acceleration pulse added for the movement of the objective lens 34 in the acceleration processing larger than the deceleration pulse impulse stopping the objective lens 34.
Abstract:
PROBLEM TO BE SOLVED: To appropriately prevent a burn-in phenomenon when a still image such as an OSD screen is displayed on a display panel.SOLUTION: When a menu screen is displayed on a video screen in a superimposed manner, a menu phrase in at least one of a left-eye video and a right-eye video is deleted for display on a menu background area. A time period is reduced in which a large brightness difference between still pixels is generated in a boundary between a menu background area and a menu phrase, and thereby the occurrence of the burn-in phenomenon can be prevented. However, the menu background area is constantly displayed without being deleted, so that screen flickering does not occur.
Abstract:
PROBLEM TO BE SOLVED: To attain a high speed and sure discrimination of the number of layers of an optical disk having three or more recording layers. SOLUTION: The optical disk drive 1 attains the high speed and sure discrimination of the number of layers of the optical disk 100 having the recording layers Y of three or more layers, since the number of layers of the optical disk 100 having the recording layers Y of three or more layers can be accurately discriminated at the time point before a focus servo is effected to the optical disk 100, by acquiring a signal level of a stray signal SN of the time point when a focus error signal SFE indicates zero cross and arranging so that the number of layers of the optical disk 100 is discriminated based on obtained whole signal levels.

Abstract:
PROBLEM TO BE SOLVED: To appropriately prevent the occurrence of a burn-in phenomenon during a display of a video in which an OSD screen is superimposed on a video screen.SOLUTION: By appropriately moving the position for displaying an OSD screen when the OSD screen is displayed on a video screen in a superimposed manner, a burn-in phenomenon is prevented from occurring in a menu background area of the OSD screen or a boundary portion between the menu background area and a menu phrase. For example, each time the OSD screen is displayed, the OSD screen is moved by one pixel and then displayed. Movement of the display position of the OSD screen is implemented by an instruction from an OSD display position control unit 215.
Abstract:
PROBLEM TO BE SOLVED: To discriminate surely and at high speed the number of layers and a kind of a recording layer of an optical disk. SOLUTION: A focal point of a light beam is approached to an optical disk 100 from a cover layer side, the last section in which a signal level of a sum signal SUM exceeds a section detection threshold value is recognized as a detection object section, when a bottom value Bn of a stray light signal X in the detection object section is more than a first stray light bottom threshold value THb1, the disk is discriminated as a dual-layer disk. Further, when the bottom value Bn of a stray light signal X on the detection object section is more than a second stray light bottom threshold value TFb2 being smaller than the first stray light bottom threshold value THb1 and the maximum amplitude Wn of a focus error signal FE in the detection object section is a first focus error threshold value TH w1 or less, the disk is discriminated as the dual-layer disk.

Abstract:
PROBLEM TO BE SOLVED: To enable performing stably tracking servo even when a center level of amplitude of a tracking signal is deviated at the time of seek for a different region in a case in which regions of two or more having different physical characteristics are formed on a disk. SOLUTION: When tracking servo operation is turned off because of seek operation astriding different regions formed in an optical disk, a center level of amplitude of a tracking error signal is calculated. And in a period in which the tracking servo is turned on, deviation of an amplitude level of the tracking error signal is canceled based on the center level calculated in this way. Thereby, when the center level of amplitude of the tracking error signal is caused in accordance with accessing the region having the different physical characteristics, this deviation can be compensated.
