摘要： A GPS positioning unit acquires GPS positioning data of an object positioned based on a signal from a GPS satellite, and an angular velocity sensor acquires an output signal of the object. A sensitivity coefficient calculation unit sequentially derives a temporary sensitivity coefficient of the angular velocity sensor based on the GPS positioning data and the output signal. The sensitivity coefficient calculation unit derives a sensitivity coefficient for correcting the angular velocity output from the angular velocity sensor, by performing statistical processing on the temporary sensitivity coefficient of the angular velocity sensor that has been sequentially derived. A correlation coefficient calculation unit derives a correlation coefficient based on the GPS positioning data and the output signal. The sensitivity coefficient calculation unit changes a forgetting coefficient to be used when the statistical processing is performed, in accordance with the correlation coefficient.

摘要： Divided periods by dividing a frame of a video signal are produced. A display element is ON-OFF controlled on a pixel-by-pixel basis according to a video signal in accordance with the divided periods preassigned to each gradation. The light amount of a light source for emitting light to the display element is controlled so that a first light amount in a first divided period corresponding to the lowest gradation except black display becomes a light amount lower than a second light amount in a second divided period other than the first divided period.

摘要： A camera thumbnail image acquisition unit acquires a first thumbnail image from a camera. A distribution server thumbnail image acquisition unit acquires a second thumbnail image from a distribution server. A thumbnail image selection unit selects one of the first thumbnail image and the second thumbnail image as a thumbnail image that should be displayed. A camera information acquisition unit acquires camera information including streaming execution information indicating whether the camera is streaming. The thumbnail image selection unit refers to the streaming execution information to select the second thumbnail image as the thumbnail image that should be displayed when the camera is streaming and to select the first thumbnail image as the thumbnail image that should be displayed when the camera is not streaming.

摘要： A bird's-eye view image generation device includes: an image data acquisition unit that acquires periphery image data obtained by photographing a periphery of a vehicle; an obstacle information acquisition unit that acquires positional information of an obstacle detected in the periphery of the vehicle; a bird's-eye view image generation unit that generates a bird's-eye view image obtained by combining periphery images acquired by the image data acquisition unit, the periphery images having been subjected to viewpoint conversion processing so that a virtual viewpoint is positioned at a position at which the vehicle and the obstacle can be overlooked, based on the positional information of the obstacle acquired by the obstacle information acquisition unit; and a display control unit that causes a display panel to display the bird's-eye view image generated by the bird's-eye view image generation unit.

摘要： A server of a video management system includes a control unit that, upon receiving the video transmission request and the affiliation information transmitted from the terminal, determines whether the video transmission request and the affiliation information correspond to a first case in which the affiliation destination indicated by the affiliation information and the affiliation destination of the affiliation video data are the same, a second case in which the affiliation destination indicated by the affiliation information and the affiliation destination of the affiliation video data are the same for a group and are different for a team, or a third case in which the affiliation destination indicated by the affiliation information and the affiliation destination of the affiliation video data are different for a group, the control unit transmitting the match video data to the terminal in the first case.

摘要： A first motion vector detecting unit calculates a first matching error by detecting a first motion vector based on a first frame and a second frame. A second motion vector detecting unit calculates a second matching error by detecting a second motion vector based on the second frame and a third frame. A local determining unit determines whether a discontinuously moving object is present in a continuously moving background, based on an absolute difference value between the first motion vector and the second motion vector, and the first and second matching errors. An integrating unit integrates determination values for each block within a frame. A determining unit determines whether an image signal is a specific moving image in which the discontinuously moving object is present in a continuously moving background, based on a pattern of integrated values of at least two frames.

摘要： Light emitted from a light source is irradiated to a reflective light modulator which modulates irradiated light to reflect based on image data and the light reflected by the light modulator is projected. A ratio of return light returning from the light modulator to the light source to the light irradiated to the light modulator is calculated based on the image data. A light amount of the light emitted from the light source is calculated by using the calculated ratio and a detection output of an optical sensor provided between the light source and the light modulator.
