【Example】

 FIG. 1 is a block diagram of an embodiment in which the present invention is applied to a vehicle-mounted image display device. The same parts as those in the configuration diagram of the conventional example shown in FIG. 5 are designated by the same reference numerals, and the description thereof will be omitted. Reference numeral 10 denotes a vehicle type information input unit, which is composed of, for example, a DIP switch or the like, and inputs the vehicle type in which the display 1 is installed. The vehicle type information input unit 10 is provided because the installation location of the display 1 (positional relationship between the driver and the display) is generally determined depending on the vehicle type. A correction data storage unit 11 stores values for correcting the display position of the image data displayed on the display 1 for each vehicle type. An image data processing unit 12 corrects the display position of the image data stored in the image data storage unit 4 with the correction value of the correction data storage unit 11 and sends it to the video signal creation unit 5. A CPU 3 operates according to the flowchart of FIG.

FIG. 2 is a flowchart showing the operation of the CPU 3. In step S1, the vehicle type in which the display 1 is installed is fetched from the vehicle type information input unit 10. In step S2, the correction value corresponding to the vehicle type is read from the correction data storage unit 11. In step S3, it is detected which of the screen changeover switches 2a to 2c has been pressed. In step S4, the image data corresponding to the pressed switch is read from the image data storage unit 4. In step S5, the image data and the correction data are sent to the image data processing unit 12 in order to calculate the display position of the image. In step S6, control is performed to convert the image data corrected by the image data processing unit 12 into a video signal.

Based on such a flow chart, the image display device according to the present invention displays an image as follows. Based on the vehicle type information input to the vehicle type information input unit 10, the CPU 3 reads the correction data for the vehicle type from the correction data storage unit 11. The correction data storage unit 11 stores, for example, data as shown in FIG. 3 for each vehicle type. In FIG. 3, the vehicle type A shows that the correction value of the X coordinate is 0 and the correction value of the Y coordinate is -8. As shown in FIG. 4, the horizontal direction of the display 1 is the X coordinate and the vertical direction is the Y coordinate.

When the operator presses any one of the screen changeover switches 2 a to 2 c, the CPU 3 reads out the image data corresponding to the switch from the image data storage unit 4 and sends it to the image data processing unit 12. In the image data processing unit 12, the display position of the image data is corrected for each vehicle type by the data from the image data storage unit 4 and the correction data from the correction data storage unit 11, and the image signal generation unit 5 corrects the image data display position. The signal is converted and displayed on the display 1.

For example, the position coordinate of the image data read from the image data storage unit 4 is X coordinate = a, Y coordinate = b, and the position coordinate of the correction data read from the correction data storage unit 11 However, if X coordinate = 0 and Y coordinate = -8, the corrected position coordinates calculated by the image data processing unit 12 are X coordinate = a and Y coordinate = b-8.

With this configuration, for example, when the menu displays 1a to 1c that look like FIG. 4A when viewed from the front of the display 1 are displayed, the display 1 is positioned relative to the position of human eyes. Conventionally, when placed diagonally downward, the positions of the menu displays 1a to 1c on the display 1 seemed to be shifted upward as shown in FIG. 4 (b). However, according to the present invention, the menu display is displayed. When the positions of 1a to 1c are shifted downward, that is, when viewed from the front of the display 1, the positions are shifted as shown in FIG. 4C, so that the display is apparently as shown in FIG. 4D. Therefore, it appears to human eyes that there is no displacement between the screen changeover switches 2a to 2c and the positions of the menu displays 1a to 1c on the display 1 corresponding to the switches.

In the above-described embodiment, an example in which the display position of the image is corrected for each vehicle type has been described. However, since the interior color of the interior of the vehicle is generally different for each vehicle type, the color on the display 1 that matches the interior color is displayed. The color of the image data may be variable. That is, based on the vehicle type information from the vehicle type information input unit 10, a color suitable for the interior color of the vehicle type is read from the correction data storage unit 11, and the display color of the image data from the image data storage unit 4 can be changed. You may allow it. In addition, if there are several interior colors for one car model, each interior color can be selected in the car model information input section 10 using a DIP switch, etc. It can be the color that most closely matches the interior color of the.

In the above embodiment, the case where the screen change switch is provided beside the display has been described. However, even when the display is a touch panel type, the switch position displayed on the screen and the switch There may be a parallax between the menu display position and the menu display position, but by correcting the menu display position or the switch display position as in the above embodiment, the shift due to the parallax can be eliminated.

Further, even when the image is simply displayed on the display without the switch, the image near the edge of the display may be difficult to see depending on the place where the display is placed. Even in such a case, by correcting the display position of the image, it is possible to shift the image to a position where it is easy to see and display the image.

In the embodiment configured as described above, the image data storage unit 4 serves as an image data generation unit, the CPU 3 serves as an image data control unit, the vehicle type information input unit 10 serves as an installation location specifying unit, and image data processing is performed. The section 12 corresponds to the display position correction means.

[0019]

[Effect of device]

 As described in detail above, according to the present invention, the image display position displayed on the display is corrected according to the installation location of the display, so that the apparent display position is displaced due to human parallax. Can be resolved. Therefore, for example, when selecting the screen change switch on the side of the display by the menu displayed on the display, even if the display installation position changes, the position of the screen change switch and the menu display corresponding to that switch are displayed. Since the position does not seem to shift, it is possible to avoid pressing the switch wrongly due to parallax.
