Description

  The present invention relates to a display device that can be moved, and in particular, it is possible to view a three-dimensional object from any direction only by changing the position or angle of the display unit, as well as enlargement, reduction, movement, etc. of a two-dimensional image. The present invention relates to a display device that can perform the above.

  In recent years, the frequency of browsing electronic documents on a PC (personal computer) monitor such as a CRT (cathode ray tube) or LCD (liquid crystal display) has been extremely high. Many of these monitors are installed on a desk as a form of device, and an operator is forced to observe a vertically leaning screen installed on the desk in a sitting position on a chair. When viewing and operating documents at this position, the distance between the operator and the monitor screen and the relative angle are almost fixed, so the worker's posture tends to be fixed, and physical fatigue and gaze continue. Eye strain caused by this has been pointed out as a work problem.

  Under such circumstances, a panel PC having a portability called a tablet PC has been developed in recent years. This conventional tablet PC includes, for example, a rectangular parallelepiped casing having a thickness of about 10 mm, an image display section that is provided at the center of the casing, and displays an image, and an operation section that performs various operations. It is.

  The operation unit includes operation buttons, a slide switch, and the like fixedly provided around the image display unit of the housing. According to this tablet PC, the user holds the tablet PC in both hands, operates the operation unit with the fingers of the held hand, or places the tablet PC on the desk or on the knee and holds the tablet PC with one hand, and the other hand. The user can operate the operation unit to change the image displayed on the image display unit.

  In recent years, there are various types of electronic documents, and it is necessary to quickly search and view a display of a three-dimensional virtual object and a wide range of materials. Conventionally, in response to such a request, for example, when a personal computer is used, it is possible to view a document displayed on a fixed display unit by operating a mouse to rotate or move a three-dimensional virtual object. Scroll through a wide range of materials. However, when viewing a 3D object, you can quickly and intuitively see where you want to see it by holding it with your hand and spreading it on your desk. It was only possible to see the object by indirect operations that took time and effort.

  In order to solve such problems, there has been proposed an image area designating device that uses a mouse and can drag and drop a predetermined position with the mouse to perform corrections such as rotation and enlargement of the image. (For example, refer to Patent Document 1).

  Further, in a display device including a display unit that displays a part of an image, a change in the position of the display unit in the horizontal or vertical direction is detected by a position detection unit including a position sensor, a speed sensor, an acceleration sensor, and the like. There has been proposed a display device that displays a part of an image fixed relative to the eyes by changing the display portion of the image information in accordance with the position change of the part (see, for example, Patent Document 2).

In addition, instructions such as model movement, rotation, enlargement, reduction, etc., operator position changes, etc. are input by an input detection unit such as a joystick or mouse, and the model moves, rotates, or enlarges as the operator approaches the model. A model display device has been proposed in which the reduction operation is delayed and the model is enlarged so that the detailed design of the model can be easily confirmed (see, for example, Patent Document 3).
Japanese Patent Laid-Open No. 2003-323241 ([0062] to [0078], FIG. 7) Japanese Patent Laid-Open No. 7-13554 ([0011] to [0017], FIGS. 1 and 2) JP 2000-20754 A ([0027] to [0034], FIG. 5)

  However, according to the conventional image area designating device, it is always necessary to operate the mouse. Therefore, when it is applied to a tablet PC, it is difficult to operate the mouse while holding the display device. It is limited to a PC provided with a display unit.

  Further, according to the conventional display device, even if the display unit is tilted, the display image does not change. Therefore, when the display unit is moved by hand as in the case of a display device such as a table tablet PC, it is natural. There is a problem that it does not look like a correct image.

  Furthermore, according to the conventional model display device, since the operator's viewpoint is virtual in the screen, in order to actually operate for the hand, a sensor for detecting the movement of the display unit is indispensable, Moreover, although distance detection is indispensable, none of the specific means are shown, and unsolved problems remain.

  Accordingly, an object of the present invention is to display a three-dimensional object that can be viewed from an arbitrary direction only by changing the position or angle of the display unit, and that can enlarge, reduce, and move a two-dimensional image. To provide an apparatus.

There is provided a display device comprising: a processing unit that processes the original image on the basis thereof; and a control unit that displays the image processed by the processing unit on the display unit.

  When the original image is a folder selection screen, the processing unit sets a virtual selection screen corresponding to the selection screen in a space, and displays the virtual image on the display unit according to the parallel movement of the display unit with respect to the virtual selection screen. A folder to be displayed may be moved, and an image in a lower hierarchy than the folder may be formed in accordance with the approach of the display unit to the folder.

  According to the display device of the present invention, since the image obtained by processing the original image is displayed based on the three-dimensional position of the display unit, the three-dimensional object can be moved from any direction only by changing the position of the display unit. In addition to being able to see, enlargement, reduction, etc. can be performed, and further, enlargement, reduction, movement, etc. of a two-dimensional image can be performed.

  When the original image is used as a folder selection screen, the folder is moved or an image of a lower hierarchy is formed in accordance with the moving operation of the display unit, so that it is easy to select a folder or a file having a hierarchical structure. .

Next, when the user operates the touch panel 32 or operates the trackball 51 and the mouse button 52, the control unit 12 reads the designated image from the image memory 17 and the LCD controller 14 causes the screen unit 30 of the display unit 3 to be read. Display an image on. Further, the control unit 12 performs page turning and scroll display on the displayed image in accordance with the operation content of the user's cross-shaped key 53.

(3D object image display operation)
Next, a display operation of a three-dimensional object image (stereoscopic image) will be described with reference to FIGS. FIG. 4 shows a three-dimensional object image (stereoscopic image) displayed on the screen unit of the display device. 5 shows a display image (two-dimensional image) obtained by viewing the three-dimensional object image of FIG. 4 from different angles, and FIG. 5A shows an image viewed from the direction A in FIG. b) is an image viewed from the direction B in FIG. 4, FIG. 5C is an image viewed from the direction C in FIG. 4, and FIG. 5D is an image viewed from the direction D in FIG. is there.

  First, the user holds the grip portion 2 with both hands and keeps the display portion 3 in a predetermined posture (for example, horizontal) at a predetermined height. A desired stereoscopic image is selected by operating the first or second operation unit 5A, 5B or the touch panel 32, and the reset switch 55 is pressed. Here, it is assumed that the stereoscopic image 40 shown in FIG. 4 is selected. By pressing the reset switch 55, the stereoscopic image 40 is virtually fixed at a certain coordinate in space. The user can view the stereoscopic image 40 (virtual image) from an arbitrary angle by moving around the virtual image while holding the grip portion 2 of the display device 1.

  For example, when the display unit 3 is moved in the direction of A in FIG. 4 while holding the display device 1 in the hand with respect to the stereoscopic image 40, as shown in FIG. 2D image) is displayed on the display unit 3. Similarly, when the display unit 3 is moved in the direction B, as shown in FIG. 5B, an image viewed obliquely from above is displayed on the display unit 3, and the display unit 3 is moved in the direction C. As shown in FIG. 5C, an image viewed from above is displayed on the display unit 3, and when the display unit 3 is further moved in the direction D, as shown in FIG. The image viewed from the right side is displayed on the display unit 3.

  Further, when the display unit 3 is brought close to the stereoscopic image 40, an image enlarged according to the distance from the reference position is displayed on the display unit 3, and when the display unit 3 is moved away from the stereoscopic image 40, the distance from the reference position is increased. The image reduced accordingly is displayed on the display unit 3.

  In this way, an image whose elevation angle is changed is displayed by moving the display unit 3 up and down, and an image whose angle is changed with respect to the vertical axis is displayed by circular movement (moving left and right). When viewed from the user, an image viewed by placing a three-dimensional object in front of the user and moving around the object appears to be displayed on the screen unit 30.

  In this way, the three-dimensional object image is always fixed and installed at a fixed angle at a fixed position, and the screen held by a hand simply functions as a window frame. In particular, not only when the screen is always moved parallel to the ground, but also when turning around a line perpendicular to the screen held by the hand, it is always viewed from the user regardless of the angle of rotation. It is also desirable to change the angle of the image in the screen so that the image can be seen in the same way.

  On the other hand, it is desirable that the image does not change when the screen held by the hand moves up, down, left, or right, and the image is changed in response to a change in angle. That is, when the user wants to view the image from the right side, it is desirable that the user can see the right side of the image only by turning or turning the screen to the right without moving to the right and turning around. Similarly, when the user wants to view the image from the upper side, it is desirable to set the user so that the upper side of the image can be seen only by turning or turning the screen downward without moving around and moving up. In this case, it is desirable that the image is enlarged or reduced with respect to the movement in the front-rear direction of the screen.

  Note that a large image change can be obtained by slightly changing the distance or angle by, for example, doubling the distance or angle that moves on the screen relative to the distance or angle that is actually held by the hand. Is also desirable.

  The display process as shown in FIG. 5 is performed by calculating the position and angle of the display unit 3 by the three-dimensional position / angle calculation unit 15 based on the information detected by the position / angle detection unit 10. Based on this, one of the images as shown in FIG. 5 is generated by the display image creation unit 16. This image is transferred to the LCD controller 14 by the control unit 12 and displayed on the LCD 33 by the LCD controller 14.

  When a desired image is displayed on the display unit 3, when the user presses the shooting switch 56, the image is stored in the image memory 17, and then read out as necessary and displayed on the display unit 3.

(Map display operation)
Next, a map display operation will be described with reference to FIG. FIG. 6 is an explanatory diagram showing an operation of enlarging or reducing a virtual image (virtual map) like a map by only moving the display device 1. First, the user holds the grip portion 2 with both hands and keeps the display portion 3 in a predetermined posture (for example, horizontal) at a predetermined height. A desired map is selected by operating the first or second operation unit 5A, 5B or the touch panel 32, and the reset switch 55 is pressed. Here, it is assumed that the virtual map 60 shown in FIG. 6 is selected. By pressing the reset switch 55, the virtual map 60 is virtually fixed at a certain coordinate in space. The user can see an arbitrary location on the virtual map 60 by moving left and right, back and forth, and up and down while holding the grip portion 2 of the display device 1 around the virtual image.

  For example, when the user moves the display device 1 directly above the corner portion of the virtual map 60 and brings the center portion of the display portion 3 onto the corner portion, as shown in FIG. An image 61 of the corner portion of the map 60 is displayed on the screen portion 30. Next, when the display unit 3 is moved directly above the center of the virtual map 60, an image 62 of the center of the virtual map 60 is displayed on the screen unit 30 as shown in FIG. When the display device 1 is moved away from the surface of the virtual map 60, an image 63 obtained by reducing the virtual map 60 is displayed on the screen unit 30 as shown in FIG. When the display unit 3 is brought close to the virtual map 60, an enlarged image is displayed. Further, if the display unit 3 is continuously horizontally moved while holding the display device 1 in the hand, the front, back, left and right of the virtual image can be seen according to the movement.

  The display process as shown in FIG. 6 is performed by calculating the position and angle of the display unit 3 by the three-dimensional position / angle calculation unit 15 based on the information detected by the position / angle detection unit 10. Based on this, one of the images as shown in FIG. 6 is generated by the display image creating unit 16. This image is transferred to the LCD controller 14 by the control unit 12 and displayed on the LCD 33 by the LCD controller 14.

  In this manner, the display device 1 can be easily scaled and moved by moving the display device 1 in the vertical direction (perspective movement) or horizontally (moving it parallel to the virtual image). In addition, an image is not limited to a map, For example, a circuit diagram, a design drawing, a photograph, etc. may be sufficient.

  Note that even when the screen is rotated around a line perpendicular to the screen held by the hand, the image on the screen and the image are attached so that the user can always see the same image regardless of the angle of rotation. It is also desirable to change the angle of the characters to be played. However, for the purpose of setting the direction on the map not only to the north but to any direction other than the north, the image is changed depending on the angle rotated around the line perpendicular to the screen you have in hand. It is also desirable to be able to select a mode in which characters are always fixed at an angle that can be read and viewed by the user without changing.

(Hierarchical image display operation)
Next, with reference to FIG. 7, the display operation of the hierarchical image will be described. FIG. 7 is an explanatory diagram showing an operation of browsing a hierarchical folder on a display device. Here, as a folder, a folder 71 including files (A-1, A-2, A-3) 711, 712, 713, a folder 72 including files (B-1, B-2) 721, 722, A folder 73 including files (C-1, C2) 731 and 732 is prepared. An image or text is recorded in each file. The folders 71 to 73 are displayed in a list format on one screen.

  First, the user holds the grip portion 2 with both hands and keeps the display portion 3 in a predetermined posture (for example, horizontal) at a predetermined height. An image of a desired hierarchical structure, that is, a list of folders is selected by operating the first or second operation unit 5A, 5B or the touch panel 32, and the reset switch 55 is pressed. Here, it is assumed that the folder list shown in FIG. 7 is selected. By pressing the reset switch 55, the folder list is virtually fixed at a certain coordinate in the space. The user can view the folder or a file under the folder (or folder) by moving the list of folders left, right, front, back, back and forth while holding the grip 2 of the display device 1 and select the folder or file. can do.

  For example, when the operation units 5A and 5B are operated while holding the display device 1, the control unit 12 displays a part of the folder list screen on the display unit 3 as shown in FIG. In the screen of FIG. 7A, the icons of folders (folders A and B) 71 and 72 are displayed, but the folder (folder C) 73 is not displayed. If the display unit 3 is moved horizontally in this state, the folder (folder B) 72 is displayed at the center of the display unit 3, and if the display unit 3 is further moved horizontally, as shown in FIG. 71 disappears and a folder (folder C) 73 is displayed in the center of the screen of the display unit 3. That is, another folder 73 in the same hierarchy can be browsed.

  In the state shown in FIG. 7A, if the display unit 3 is moved upward, the list screen is reduced and all the folders 71 to 73 can be viewed at the same time.

  Next, in the state of (b) in FIG. 7, if the display unit 3 is lowered so as to approach the image as it is, the display unit 3 has a lower hierarchy of the folder 73 as shown in (c) of FIG. 7. Files 731 and 732 are displayed. Here, the target file is selected by operating the touch panel 32 or the cursor.

  The hierarchy switching is configured to be performed when the vertical position of the display unit 3 exceeds a predetermined position.
