22 (corresponding to the first image data storage unit 131 in FIG. 1) and the drawing IC 223 (the first processing unit 13 in FIG. 1).
2, the second processing unit 133 and the data cutout unit 135
Is equivalent to ) And a drawing RAM 224 (corresponding to the second image data storage unit 134 in FIG. 1).

The image data ROM 222 stores three-dimensional data of the continuous annular body S as shown in FIG. 5 and image data of a character (see FIG. 7) indicating the control state of the air conditioner, and a drawing IC 223. , These data are sequentially read.

The drawing IC 223 cuts out a plurality of discontinuous annular bodies D as shown in FIG. 5 from the three-dimensional data of the continuous annular bodies S stored in the ROM 222 for image data. The character C according to the control state is read from the image data ROM 222 and written into the three-dimensional data of the cut annular body D.

Here, the three-dimensional data of the ring-shaped body D on which the character C is written is converted into data in a range wider than the display range of the display 21 by the drawing RAM 22.

In FIG. 2, the control ROM 225 stores a program for performing information processing other than the drawing process in accordance with a command from the operation switch 23 or the like, and uses the memory area of the microcomputer 221 and the control RAM 226. Such processing is performed.

Next, the image processing procedure will be described. The monitor device 1 of the present embodiment selectively displays, on one liquid crystal display 21, a control state image of an air conditioner as shown in FIG. This selection can be performed by pressing the menu switch 238 of the operation switch 23 shown in FIG.

A screen showing the control state of the air conditioner is displayed as a three-dimensional image as shown in FIG. 7, and has an expression effect equivalent to that of a computer graphic. These images are processed according to the following procedure and the liquid crystal display 2
1 is displayed.

First, the image data ROM 222 stores the three-dimensional data of the virtual donut shape S shown in FIG. 5, and the drawing IC 223 positions the three-dimensional data of the virtual donut shape S in front. From the data of the area, five three-dimensional data of the drum shape D shown in the figure are cut out from here (D1 to D5 from the left in the figure). The extracted drum shape data D
Since 1 to D5 are generated based on the three-dimensional data, they are displayed three-dimensionally as shown in FIG.

At this time, the three-dimensional data D1 to D5 of the drum shape to be cut out are converted into data for drawing R as data of a range B wider than the display range A of the actual display 21.
AM 224 is written once. The above is the drawing IC 22
3 is a process of reading from the image data ROM 222 and a process of extracting the drum shape data D.

Next, as shown in FIG.
The control state of the air conditioner is attached to each of the two drum shape data D1 to D5. Here, from the left, a drum D1 indicating automatic control or manual control, a drum D2 indicating a current set temperature, a drum D3 indicating a current air volume (that is, a fan rotation speed), and a drum D4 indicating a current outlet mode, The drum D5 at the right end is not used.

The character C representing the control state attached to each of the drums D1 to D5 is, for example, a number or a figure as shown in FIG. Even at “28 ° C.”, each shape is stored according to the position where it is attached. In other words, since the drum D2 indicating the current set temperature has five portions to which the character C is pasted, the numbers "28 ° C." having five types of shapes are stored in the image data ROM 222. The same applies to other characters C. In FIG. 7, in order to indicate the control state value located on the surface of each of the drums D1 to D5 as the current control state, the character C attached to the front has a different color from the other characters C. .

In the drawing IC 223, such a character C is displayed on the image data RO in order to display the current control state based on the detection signal from the air conditioner controller 24.
The data is selected from M222, read out, and pasted on each of the drum shape data D1 to D5 stored in the drawing RAM 224. This data is also stored in the drawing RAM as data in a range B wider than the display range A of the display 21.
224.

Then, in accordance with the cursor position, the drawing R
Data corresponding to the display range A of the display 21 is cut out from the AM 224 and transmitted to the display 21. The state thus pasted is the image shown in FIG. In this example, the control state of the air conditioner is represented by using five drums D1 to D5.
5 cannot be displayed on the display 21, a part of the undisplayable drums (here, D1 and D5) is displayed on both sides of the screen as shown in FIG. To the user.

To change the set temperature from this state, for example, the roller push switch 239 of the operation switch 23 and the right or left switch 240, 2 shown in FIG.
Use 41. For example, now the display 21 is
It is assumed that the drums D1 to D3 are displayed as shown in FIG. 8A, and the cursor position (the black portion in FIG. 8) is on the drum D1. Since the drum D for displaying the set temperature is the drum D2 on the right of the drum at the current cursor position, first, the right switch 240 is pressed to move the cursor position one position to the right. As a result, the display range A of the display 21 shifts to the drums D2 to D4 as shown in FIG. 3B, and on the display 21, it looks as if the drums D1 to D5 have moved left and right.

Since the change processing of the display range A by the right switch 240 is performed only by changing the cutout range from the wide area B data written in the drawing RAM 224, a high-speed and unnecessary memory area is used. Can be done without. In the embodiment shown in FIG. 2B, the entire display range is moved by one to the right even if the cursor is moved by one to the right from FIG. Are the drums D2 arranged in the center
This is because the display content of D4 is a control state value having priority and importance. Therefore, only the cursor may be moved to the right without changing the display range A as shown in FIG.

As shown in FIG. 8B, when the cursor position is located on the drum D2 indicating the set temperature, the roller push switch 239 is turned with a finger so that the target set temperature comes to the front position. Manipulate. When the roller push switch 239 is turned in either direction, the encoder signal is sent to the drawing IC 223 via the microcomputer 221, and the characters C of the drum shape data D1 to D5 written in the drawing RAM 224 are transferred to the encoder. Paste according to the rotation angle. As a result, on the display 21, it appears as if the drum D is rotating.

Then, when the target set temperature reaches the front position, the roller push switch 239 is pressed. Thereby, the microcomputer 2 of the monitor controller 22
A signal to change the set temperature is sent from the air conditioner 21 to the air conditioner controller 24.

As described above, according to the monitor device 1 of the present embodiment, it is possible to provide a monitor display which has a three-dimensional effect and a continuous effect on the display 21 and is easy to use. Further, such three-dimensional data can be processed at high speed by effectively using the drawing RAM 224,
There is no need to increase the memory capacity or use a high-speed CPU.

The embodiments described above are described for facilitating the understanding of the present invention, and are not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

For example, in addition to the donut shape shown in FIG. 5, the annular body S of the present invention may adopt, for example, a straight pipe shape S shown in FIG. 9 or a conical shape S shown in FIG.
Any shape can be adopted as long as it is a continuous annular body S.

[0041]

As described above, according to the on-vehicle monitor device of the present invention, a plurality of discontinuous annular bodies are cut out from the continuous annular body, and a character corresponding to the control state is pasted on the discontinuous annular body. Therefore, the display means displays an image having a three-dimensional effect and as if individual discontinuous bodies are continuous.

In this case, the plurality of discontinuous annular bodies are cut out from the three-dimensional data of the continuous annular bodies stored in the first image data storage unit, so that a large-capacity storage device is not required. In addition, high-speed processing can be performed without complicated calculation processing.

Further, the three-dimensional data obtained by the second processing unit is stored in the second image data storage unit as data in a range wider than the display range of the display means, and the three-dimensional data to be sent to the display means is stored. By cutting out a part of the image data from the second image data storage unit, exchange of three-dimensional data can be executed only by the second image data storage unit, and a large-capacity storage device is not required. In each case, high-speed processing can be performed without complicated calculation processing.
