A mobile body controller according to the present disclosure includes circuitry configured to recognize an environment surrounding a mobile body to be controlled, and change parameters used for self-position estimation by the mobile body based on the recognized environment.

Mobile body, method of controlling mobile body, and program

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.

Control device, imaging device, control method, imaging method, and computer program

Achieved is an autonomous traveling control device which generates a safety priority path for avoiding passage through or approach to a dangerous region where a contact with another mobile object is possible, and travels along the safety priority path. The autonomous traveling control device includes a traveling path determination unit that generates a safety priority path for avoiding passage through or approach to a dangerous region where a contact with another mobile object is possible; and a traveling control unit that executes control causing the own device to travel along the safety priority path generated by the traveling path determination unit. The traveling path determination unit generates a cost priority path in a metric map on the basis of a minimum cost path in a topology map, and generates a safety priority path bypassing the dangerous region by correcting the cost priority path in the metric map.

Provided is an information processing device that includes a planning unit that sets a joining route on the basis of information about at least one of a planned route of a user mobile unit that uses a service or a planned route of a provider mobile unit that provides the service, the joining route being a zone for the user mobile unit and the provider mobile unit to receive and provide the service, and makes a movement plan including at least one of a route plan for the user mobile unit or a route plan for the provider mobile unit based on the joining route. The information processing device further includes a service provision unit that controls provision of the service so that the user mobile unit and the provider mobile unit receive and provide the service while moving on the joining route.

Information processing device, information processing method, and mobile unit

[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.

To appropriately prevent a burn-in phenomenon when a still image such as an OSD screen is displayed on a display panel. 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 on a menu background area. A time period in which a brightness difference between still pixels in a boundary between a menu background area and a menu phrase remains large is reduced, and thus 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.

Head mount display and display control method

Provided is a head mounted display including a displaying unit to display an image, an image signal processing unit to process an image signal, a display control unit to perform an image quality adjustment of the image signal processed by the image signal processing unit, and to control a display in the displaying unit, a mounting sensor to detect whether an observer has mounted the apparatus, and a control unit to issue an instruction for the image quality adjustment of the image signal in the display control unit, in response to a detection result by the mounting sensor.

Head mounted display and display control method

A recording and reproducing apparatus is provided, which includes a rotary drive unit, an optical pickup unit, an adjustment unit which compensates for changes in characteristics of the laser light caused by changes in temperature, a temperature detection unit which detects a temperature of the optical pickup unit, an evaluation value generation unit which generates an evaluation value based on reflected light information, and a control unit. The control unit performs a temperature acquisition process, an optimum point adjustment process, a temperature acquisition process for acquiring a detected temperature during spin down, an optimum point search process, and a temperature characteristic compensation operation coefficient calculation process for performing temperature compensation with respect to the adjustment values.

Recording and reproducing apparatus, method of calculating temperature characteristic compensation operation coefficient, and reproducing apparatus

An optical disk apparatus can reliably detect the target recording layer of an optical disk having two recording layers. The optical disk apparatus is adapted to recording information on and reproducing information from an optical disk formed by sequentially laying a first recording layer, a second recording layer and a cover layer. The focal point of the light beam is moved closer to the optical disk from the side of the cover layer and the focal point of the light beam is determined to be coming close to the recording layer when the signal level of the focus error signal falls below a positive focus error threshold value after rising above the latter or rises above the negative focus error threshold value after falling below the latter. Then, the focal point of the light beam is kept on moving toward the optical disk after the detection of the recording layer and the recording layer that is detected last is determined to be the first recording layer when the recording layer is not re-detected within a re-detection period.

Optical disk apparatus, focal position control method and focal position control apparatus

A code conversion method that may be used for uniquely converting n-bit codes inclusive of those capable of being converted into first and second m-bit data, where n&gt;m. With the present method, a conversion table may be reduced for reducing the size of the conversion circuit. At a step S1, a status bit specifying whether or not a n-bit code next following the n-bit code being converted is a first pre-set codestring. At a step S2, the n-bit codes are split into a first code made up of upper k bits, where 0&lt;k&lt;n, and a second code made up of lower n-k bits. At a step S3, the result of conversion is obtained from a conversion table outputting m-bit data associated with n-bit codes represented by the combination of the first and second codes, with account being taken of the status bit. Second m-bit data are allocated to the combinations of the first and second codes constituting the n-bit code capable of being converted into two m-bit data are allocated to those addresses of the conversion table which are associated with the combinations of the first and second codes excluded by the minimum run-length limitations for the n-bit codes.
