1. An on-vehicle device comprising:

  • a peripheral situation detector that detects a situation of a periphery of an own vehicle;

    a display that is able to display an image, on a front windshield glass of the own vehicle, in a manner of being superposed on a scene of a real space at a vehicle front side of the own vehicle;

    an eye detector that detects a height position of eyes of a driver of the own vehicle; and

    at least one processor programmed to;

    support driving of the own vehicle by the driver by controlling the own vehicle based on the situation of the periphery of the own vehicle that was detected by the peripheral situation detector;

    generate image data, in which marks for driving support of the own vehicle are drawn so as to be superposed on a forward situation diagram that shows a situation at a front side of the own vehicle, based on the detected situation of the periphery of the own vehicle and information obtained from supporting the driving of the own vehicle;

    set a vanishing point in accordance with the height position of the eyes of the driver and compute a display image depicted by a one-point perspective drawing method from the detected height position of eyes of the driver and the generated image data;

    cause the display image to be displayed on the front windshield glass by the display such that the vanishing point is set in accordance with the height position of the eyes of the driver based on the detected height position of the eyes of the driver, wherein;

    the marks include a first mark, that is shaped as an arrow and shows a traveling direction of an other vehicle in the detected situation of the periphery of the own vehicle, and a second mark, that is shaped as an arrow and shows a planned traveling direction of the own vehicle; and

    the first mark includes, in order from a tip end of the arrow toward another end of the arrow, a distal end portion, a first intermediate portion, a second intermediate portion and a near portion;

    in response to determining that an inter-vehicle distance between the other vehicle and the own vehicle is smaller than a threshold value that is set in advance;

    display the first intermediate portion, the second intermediate portion and the near portion of the first mark; and

    not display the distal end portion of the first mark; and

    in response to determining that the inter-vehicle distance between the other vehicle and the own vehicle is greater than or equal to the threshold value;

    display the distal end portion, the first intermediate portion and the second intermediate portion of the first mark; and

    not display the near portion of the first mark.
