  • Publication number: 20220284543
    Abstract: A pixel is appropriately interpolated regarding a histogram image in which a distance histogram is allocated to each pixel position. A signal processing apparatus according to the present technology includes a histogram generation unit that inputs a histogram image in which a distance histogram indicating results of a plurality of times of distance measurement as frequency information for each distance is allocated to each pixel position and generates a distance histogram of an interpolation target position in the histogram image on the basis of distance histograms of a plurality of pixel positions near the interpolation target position.

  • Publication number: 20220137193
    Abstract: A measurement apparatus (1a) according to an embodiment includes: a first pixel (10); a light source (131); a control unit (150) that controls emission of light emitted from the light source by generating light emission commands that allow the light source to emit light; a first measuring unit (133ref) that measures a first time period between a first light emission command timing at which the control unit generates a first light emission command out of the light emission commands and a light emission timing at which the light source emits light in accordance with the first light emission command; second measuring units (1331, 1332, 1333, and . . . ) each of which measures a second time period between a second light emission command timing at which the control unit generates a second light emission command out of the light emission commands and a time at which the light is received by the first pixel; and generating units (1401, 1402, 1403, and . . .

  • Patent number: 10460185
    Abstract: A system and method for roadside image tracing are described herein. The system includes a camera mounted on a vehicle configured to capture images of objects around the vehicle while driving along a route of a plurality of routes, and processing circuitry. The processing circuitry is configured to receive the captured images from the camera and vehicle parameters including speed, a fuel level, and a mileage, extract objects and locations of the objects within the captured images including information related to driving, determine a route ranking based on the information collected from the objects during one or more trips along each route of the plurality of routes, generate route options based on the route ranking and the vehicle parameters, and transmit route options to a display.

  • Patent number: 10303339
    Abstract: A vehicular human-machine interface, an instrument cluster and a method of providing information to a driver of a vehicle. The interface includes a multi-information display that provides a driver numerous dynamically-adjustable icons that are representative of a vehicle systems such that the driver can view, and if necessary, control through the interface. During use by a driver to navigate among the various icons being displayed, the human-machine interface enhances a driver's visual acuity by providing notorious indicia of the status of a particular vehicle system that may be of interest to the driver. In addition, by having certain information be arranged in a dynamic presentation format for selective viewing rather than arranged statically, certain information not of immediate interest can be temporarily removed, thereby freeing up the display to show a larger number of the icons on any particular screen being viewed.

  • Publication number: 20180074687
    Abstract: A vehicular human-machine interface, a dashboard and a method of providing information to a driver of a vehicle. The interface includes a multi-information display that provides a driver icons that are representative of a vehicle systems such that the driver can view, and if necessary, control through the interface. Input is simplified through a reduced set of directional buttons on a steering wheel-mounted four-way switch. By eliminating a separate BACK button from the steering wheel, driver input operations to achieve navigational control between various vehicle system menus that correspond to the icons, as well as sub-menus within a particular vehicle system, is simplified. The simplified navigation that is either between various icons on the display or various menu-based levels that can be sequentially shown also permits, in addition to viewing various vehicle system operational parameters, the ability to change such parameters through adjustment through the human-machine interface.

  • Publication number: 20170206045
    Abstract: A first-screen is continuously displayed on a display according to contents of the first-screen, in a case where a first display request is cancelled before a continuous display time in which the first-screen based on the first display request has been continuously displayed on the display, reaches a predetermined reference time. Meanwhile, after display of the first-screen has been continued and before the continuous display time of the first-screen reaches the reference time, in a case where a second display request making an instruction for displaying a second-screen to be displayed at a highest priority occurs, the display is switched from the first-screen to the second-screen at a time when the second display request occurs, and, in a case where the second display request does not occur, the first-screen is displayed on the display until the continuous display time of the first-screen reaches the reference time.
