JVC

Victor Company of Japan, Ltd , TYO: 6792, usually referred to as JVC, is a Japanese international consumer and professional electronics corporation based in Yokohama, Japan. Founded in 1927, the company is best known for introducing Japan's first televisions, and for developing the Video Home System video recorder.From 1953 to 2008, Matsushita Electric Industrial Co., Ltd. was the majority stockholder in JVC. In 2008, JVC merged with Kenwood Corporation to create JVC Kenwood Holdings. Wikipedia.

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.


An object is to notify a user of a communication terminal of a specific content of a danger. An on-vehicle video system (1) according to the present invention includes a camera (10) configured to capture images of surroundings of a vehicle, an information processing unit (11) configured to identify a person and a communication terminal in a captured image, and a communication unit (12) configured to send the captured image to the communication terminal. The on-vehicle video system (1) achieves a video transfer system by identifying a communication terminal in the captured image and sending the captured image to an identified communication terminal via base station devices and a network.


A diagnosis supporting device includes a display, an imaging unit configured to capture a subject, an eye gaze detector configured to detect an eye gaze direction of the subject from a captured image captured by the imaging unit, a gaze point detector configured to detect a gaze point of the subject in a display region of the display, based on the eye gaze direction, an output controller configured to display, on the display, a diagnosis image that includes a person image and a geometric pattern image, and in which at least one of contrast, color density, and a degree of transmittance of the person image or the geometric pattern image is changed over time, and an evaluator configured to calculate an evaluation value of the subject, based on the gaze point detected by the gaze point detector when the diagnosis image is displayed.


A uniformity correction data generation unit generates uniformity correction data for an R signal, a G signal, and a B signal. A multiplier multiplies pixel signals of the R signal, the G signal, and the B signal by the uniformity correction data for the R signal, the G signal, and the B signal. The multiplier shifts, from one another, positions of pixels at a time of multiplying the pixel signals of the R signal, the G signal, and the B signal by the uniformity correction data for the R signal, the G signal, and the B signal.


A first level converter performs level conversion for a first digital signal into a second digital signal. A second level converter performs level conversion for a third digital signal into a fourth digital signal. An arithmetic unit generates a fifth digital signal obtained by subtracting the fourth digital signal from the second digital signal, and a sixth digital signal obtained by adding the first digital signal and the fourth digital signal to each other. A first DA converter performs DA conversion for the fifth digital signal into a first analog signal. A second DA converter performs DA conversion for the sixth digital signal into a second analog signal. An adder adds the first analog signal and the second analog signal to each other to generate a third analog signal.


A prediction information derivation unit derives inter prediction information candidates from inter prediction information of coded prediction blocks neighboring a prediction block subject to coding within the same picture as the prediction block subject to coding and inter prediction information of a prediction block in a coded picture that is different from the prediction block subject to coding. The prediction information derivation unit determines an inter prediction information candidate to be used for inter prediction of the prediction block subject to coding from the inter prediction information candidates that have been derived. A second bitstream generation uni codes an index that indicates the inter prediction information candidate based on the number of the inter prediction information candidates.


An image drawing device (1) includes: a laser light source controller (6) configured to control a laser light output timing of a laser light source unit (3) and an output value of laser light so that a drawing image based on input image data is generated in a scanning region scanned by a scanner unit (4); a scanner controller (7) configured to control scanning of the scanner unit (4) so that the scanner unit (4) scans the laser light with a predetermined amplitude; and a characteristic detection controller (8) configured to control the scanner controller (7) to perform scanning in a range in which an amplitude of scanning of the scanner unit (4) exceeds a scanning range corresponding to a predetermined amplitude when the output value of the laser light output from the laser light source unit (3) is adjusted, control the laser light source controller (6) to output characteristic detection laser light during scanning in a range which is outside of a range in which the drawing image is generated and beyond the scanning range corresponding to the predetermined amplitude, and adjust the output value of the laser light based on a detection result of the output value of the characteristic detection laser light.


A rearview mirror with a display function (1) includes a display panel (30) that displays a picture of a rear camera (51) of a vehicle, and a half mirror (22) provided in a display surface of the display panel (30). A motion sensor (40) performs motion detection. A switching control unit (108) performs processing of switching a mode to a display mode, in a motion detection result in any direction of directions detected by the motion sensor (40), when the rearview mirror with a display function (1) functions as a mirror mode, and processes the motion detection detected by the motion sensor (40) as a moving instruction of a display range to each of the detected directions, when the rearview mirror with a display function (1) functions as the display mode.


A prediction information deriving unit derives the inter-prediction information candidates from inter-prediction information of a prediction block neighboring to a coding target prediction block or a prediction block present at the same position as or near the coding target prediction block in a coded picture at a temporally different position from the coding target prediction block. A candidate supplementing unit supplements inter-prediction information candidates having the same prediction mode, reference index, and motion vector until the number of inter-prediction information candidates reaches the designated number of candidates when the number of inter-prediction information candidates is smaller than the designated number of candidates.
