Provided, in response to the movement / rotation amount of the display unit detected by the movement amount sensor 13a and the rotation angle sensor 13b,
There is a display means for selectively displaying the image data in the image memory 10,100, and the display means is the image memory 1
From the movement point A of the display unit 1 in 0,100 to the normal direction indicated by the display unit 1 and the predetermined rotation angle α direction, the predetermined offset angle β direction, and the offset amount from the movement point A. Means for displaying image data of a predetermined area of m (≦ n) dimensions of d (specifically, means for transferring and displaying from the image memory 10,100 to the display memory 11,110) are necessary for carrying out the present invention. It is a means.

The structure and operation of the display device of the present invention will be described below with reference to FIGS. FIG. 1 (a) shows a configuration example of the display device of the present invention, and FIG. 1 (b) shows a case where an image in the two-dimensional image memory 10 is displayed.

In the display device shown in FIG. 1A, the display unit 1 is moved after the image data from the host is stored in the image memory 10,100 via the interface unit under the control of the control unit, for example. After moving on the rail 12a, the image data seen from the display unit 1 when the display unit 1 is rotated by α degrees with respect to the normal direction indicated by the display unit 1 by the rotating means 12b. Clip from image memory 10,100 and transfer to display memory 11,110 for display.

In this embodiment of the display shown in FIG. 1 (b), the display unit 1 can be moved left and right on the moving rail 12a, for example. The transfer rail
The amount of movement of the position above 12a from a predetermined starting point (for example, the leftmost end) O is detected by the movement amount sensor 13a.

Based on the movement amount detected by the movement amount sensor 13a, the image data of the image memory 10 in the range corresponding to the current position of the display unit 1 is clipped (transferred) and transferred to the display memory 11. , Position A shown in FIG.

, The movement of the display unit 1 is limited to the horizontal direction. However, if the image memory is a three-dimensional image memory, in addition to the horizontal direction, movement in the depth direction,
Image data in the three-dimensional image memory when the display unit 1 is rotated by a predetermined angle α at the moving position A is clipped to display memory (the display memory in this case is also three-dimensional memory). It can be transferred to the 110 and displayed.

2 and 3 schematically show display examples in this case. First, in FIG. 2, the display unit 1 is moved from a starting point (for example, the lowermost end and the leftmost end of the three-dimensional image memory 100 shown in the figure) O, on the moving rail 12x in the X-axis direction to the right by a predetermined amount ( xd) Rails for moving in the Y-axis direction after moving
A predetermined amount (yd) is moved upward on the 12y, and further, a predetermined amount (zd) is moved on the moving rail 12z in the depth direction (Z-axis direction in the figure) in the depth direction.

Considering the image data when the three-dimensional image memory 100 is viewed at the destination A, the destination A
By clipping the image data in the area of the display memory 110 on the xy plane at, and transferring to the display memory 110 for display, the image data at the destination A in the three-dimensional image memory 100 is displayed. can do. The display memory 110 in this case may be a two-dimensional memory.

When the image data of the offset amount d is clipped and displayed from the destination A, the display memory 110 is a three-dimensional memory, and the image data of the rectangular column area corresponding to the offset amount d is displayed. , The display memory 110
, And displays a three-dimensional image that has been subjected to hidden surface processing in which the maximum Z value is d, for example.

The display unit 1 with respect to the normal direction of the display unit 1, for example,
The above two-dimensional image or three-dimensional image that is rotated by an angle α in the upper (lower left / right) direction and is offset angle β {β = 0 is the direction rotated by the angle α in the upper (lower left / right) direction}. The case where an image is displayed is shown.

When the offset amount d = 0 in each direction,
When the above-mentioned two-dimensional image is obtained and the offset amount d ≠ 0, as described above, the image data of the rectangular prism region is transferred to the three-dimensional display memory 110, and the maximum value of the Z value is d. Display a three-dimensional image that has undergone hidden surface processing.

These two-dimensional image and three-dimensional image display techniques are based on known display techniques and are not a feature of the present invention. The feature of the present invention is that the display unit 1 is moved in the vertical and horizontal directions, and at the moving point A, the display unit 1 is further moved in the horizontal direction (in the figure, the xz plane) in the vertical and horizontal directions.
The image data in the three-dimensional image memory 10,100 when changed by a predetermined angle α is clipped (cut out) and transferred to the display memory 11,110, and the two-dimensional image,
Or, it is in the place of displaying a three-dimensional image. At this time,
The offset amount d in the normal direction of the display surface of the display unit 1 and the image data in the offset angle β direction can also be displayed.

In the above embodiment, the three-dimensional display space has been described as an example, but it goes without saying that the display space may be generally expanded to the n-dimensional display space. As described above, the display device of the present invention includes an image memory that stores n-dimensional image data, a display unit, a unit that moves and rotates the display unit in the n-dimensional direction, and a movement amount in the n-dimensional direction. , Equipped with a movement amount sensor that senses the rotation angle and a rotation angle sensor, and changes the display content in response to the movement amount and the rotation amount of the display unit detected by the movement amount sensor and the rotation angle sensor.
