  The control means 20 includes, for example, a storage device such as a microcomputer, graphic controller, ROM, RAM, flash memory, etc., and predetermined input information from the vehicle side ECU that is input through the in-vehicle LAN (in this case, for example, a vehicle speed sensor, It includes elements necessary for driving and controlling the image display device 10 in accordance with information from the engine rotation sensor and fuel sensor) and displaying an image to be described later.

  On the display screen of the image display device 10, as the image, when the vehicle speed does not exceed 60 km / h (predetermined value) (from 0 km / h to 60 km / h), as shown in FIG. As a display mode, the first pointer-type display image (information image) GR1 that displays the vehicle speed (vehicle information) in an analog manner in the center is displayed, and the second pointer-type display that displays the vehicle engine rotation (vehicle information) in an analog manner on the left side. An image (information image) GR2 is displayed adjacent to each other at intervals with a third pointer-type display image (information image) GR3 that analog displays the remaining fuel amount rotation (vehicle information) on the right side. A decoration image GR4 that decorates the third pointer type display images GR1 to GR3 is displayed. Note that whether or not the vehicle speed exceeds a predetermined value is determined based on speed information input to the control means 20.

  Each of the pointer-type display images GR1 to GR3 is displayed as a moving image by reading and reproducing image data including a plurality of patterns stored in the storage device based on predetermined input information input by the control unit 20 through the in-vehicle LAN. Each is provided with a rotating pointer 31 and an index portion 32 that is an instruction target of the pointer 31.

  The decoration image GR4 includes a decoration ring R that borders the outside of each pointer type display image GR1 to 3, and a circular pattern pattern P that constitutes the inner background of each pointer type display image GR1 to 3. The ring R has a gradation pattern in which the color gradually increases from the center of the design of each pointer type display image GR1 to 3 toward the outside, and the pattern pattern P corresponds to each of the pointer type display images GR1 to GR3. It has a gradation pattern in which the color gradually decreases as it goes outward from the center of the design, and the three-dimensional effect is given to each of the pointer-type display images GR1 to 3 by these decorative images GR4.
