[0055] based on figure 1 , the structure of the display unit included in the vehicle device mounted on the vehicle will be described. The display unit 6 is composed of a color filter 1, a liquid crystal layer 2, a TFT (Thin Film Transistor) 3, a backlight 4, and the like.
[0056] The color filter 1 is a film printed with three primary colors (RGB) for each pixel. The liquid crystal layer 2 is a so-called liquid crystal shutter whose molecular alignment changes upon application of an external voltage or the like. TFT3 changes the molecular arrangement of the liquid crystal in the liquid crystal layer 2 corresponding to the target element by controlling the electrodes arranged in a matrix and applying voltage to the matrix-shaped target element, so that the light from the backlight 4 is transmitted to the color filter 1 side thin film transistors. The backlight 4 includes a plurality of light emitting diodes (LEDs (Light Emitting Diodes)) 5 as light sources, which a...
Deformed example 1
[0098] In the representative embodiment described above, the outer areas S1 and S2 are defined outside the left and right sides of the navigation guidance area M. However, if Figure 6 As shown, the outer area S3 may be defined only outside one of the left and right sides of the navigation guidance area M. The image analysis unit 14 sets the predetermined outer region S3 as a black image.
[0099] In this case, as Figure 6 As shown, the light quantity determination unit 17 determines to cause the LEDs 5A to 5M corresponding to a certain area M in the car navigation image G3 to emit a certain amount of light. In addition, the light quantity determination unit 17 determines that the LEDs 5N to 5U corresponding to the outer area S3 in the car navigation image G3 are not to emit light.
[0100] In addition, in step SA7, if Figure 6 As shown, the control unit 11 makes the LEDs 5A to 5M corresponding to the fixed area M in the car navigation image G3 emit a certain amount of li...
Deformed example 2
[0103] In the representative embodiment described above, although a certain area of the map image centered on the position mark J of the vehicle is defined as the navigation guide area M, as in Figure 7 As shown in FIG. 2 , an area narrowed so as to accommodate a wider range of map images within a certain range may also be specified as the navigation guidance area M. The image analysis unit 14 thereby defines the navigation guide area M, and defines the outer area S4 and the outer area S5 outside the navigation guide area M.
[0104] In addition, in this case, the image analysis unit 14 may increase the reduction ratio of the navigation guidance area M as the distance from the vehicle position mark J increases.
[0105] Thus, since the own vehicle position marker J displayed as an important display in the navigation image and images in its vicinity are displayed in detail, and the amount of information of images less important than it is reduced, the marker J can be display...
