  However, in order to display a new image object on the screen using an existing input device, a certain amount of knowledge is required, and thus it cannot be easily used by a person who has no knowledge. When a new image object is displayed on the screen using an existing input device, the usage pattern of the image object is limited due to the input mode. This has been an obstacle to the idea of how to display and use new image objects.

  An object of the present invention is to provide an image display device that can easily cause a new image object to appear on a display screen using a new image object input command generation device attached to a case holding an image display unit. There is.

  Another object of the present invention is to provide a new image object input command generation device that makes it possible to conceive a new display method and use method of an image object that cannot be considered in the conventional input device. .

  The present invention basically includes an image display unit having a display screen, a case for holding the image display unit, an image data storage unit, an image change command generation unit, a new image object input command generation device, Image display control means. The image data storage means stores image data of an image to be displayed on the display screen, such as an image of an image object or a background image. The image display control means displays an image on the image display unit based on the image data stored in the image data storage means, changes the image accordingly when an image change command is input, and based on the input command, An image object is displayed on the display screen.

  More specifically, the new image object input command generating device includes an input command generating device main body, a mounting structure for attaching the input command generating device main body to the case so as to form a predetermined positional relationship with the display screen, and a display. When the positional relationship detecting means for detecting the positional relationship between the screen and the input command generating device main body, the operation unit operated when generating the input command provided in the input command generating device main body, and the operating unit are operated An input command generation unit that generates an input command including the above-described positional relationship, and a signal transmission unit that transmits the input command to the image display control unit are provided. The image display control means has a function of determining the expression position of the display screen of the image object based on the positional relationship included in the input command, and causing the image object to appear on the display screen from the expression position.

  According to the present invention, the input command generated by operating the operation unit of the new image object input command generating device attached to the case includes information on the positional relationship between the display screen and the input command generating device main body. . The image display control means determines the expression position of the image object on the display screen based on the information on the positional relationship, and causes the new image object to appear on the display screen. Therefore, according to the present invention, even a user who does not have special knowledge can operate the operation unit of the dedicated new image object input command generation device attached to the case, on the display screen related to the attachment position. A new image object can be easily expressed at the position. Also, a new image that could not be considered in the past, for example, a new image object input command generation device attached to the case, and a new image image that is displayed in such a manner that the image object enters the display screen. It is possible to conceive how to display and use objects.

  Preferably, the case includes a frame portion surrounding the periphery of the display screen, and the attachment structure portion is configured to attach the input command generation device main body to the frame portion so that the position of the input command generation device body can be changed. With this configuration, a new position can be obtained by arbitrarily selecting the attachment position of the input command generation device body and operating the operation unit of the new image object input command generation device attached to the case frame while viewing the display screen. An image object can be expressed on the display screen. In particular, when it is provided in the frame, it is possible to express the image object directly from the input command generator main body attached to the frame, and it is possible to display an image object that has never been seen before. It becomes possible.

  As the positional relationship detecting means for detecting the positional relationship between the display screen and the input command generator main body, various configuration methods are conceivable. For example, the positional relationship detection means includes a plurality of position detection markers that are provided on the frame and whose positional relationship with the display screen is specified, and marker detection that is provided on the input command generator main body and detects the position detection markers. Means. The position detection marker can be constituted by a seal or the like having an adhesive surface. If the position for providing the position detection marker of a specific shape is determined in advance as the center position of the side of the frame, by placing another position detection marker with reference to the position detection marker of the specific shape, The positional relationship between the input command generator main body and the display screen can be specified. In this case, it is only necessary to attach the position detection marker to the frame portion of the case, so that complicated setting is not necessary and the removal is easy. Also, if a position detection marker is provided in the case frame, the distance between the input command generator main body and the position detection marker can be minimized, and the thickness of the frame need not be considered.

For example, there is a method of changing the blinking speed of the position detection marker image according to the position. In addition, the position detection marker image can be set so that the color or illuminance differs depending on the position. If the marker of the positional relationship detection means is configured by displaying the image on the display screen in this way, it is not necessary to prepare another member other than the input command generator main body for detecting the positional relationship. Therefore, the position of the input command generator main body attached to the frame portion can be detected with a small number of parts and with high accuracy.

Further, the positional relationship detection means may be constituted by an input command generator main body provided with two positional relationship detection sensors and a reflector. The positional relationship detection sensor includes a light emitting portion and a light receiving portion that receives light emitted from the light emitting portion and reflected by the reflecting plate , and is provided at a predetermined interval in a frame portion of the case.

With this configuration, the positional relationship detection sensor may be installed at any position on the case frame regardless of the length of the case frame.

  Further, when the rail structure is fixed to the frame portion of the case and the mounted structure portion that can be attached to the rail structure so that the position can be changed along the rail structure is provided in the input command generator main body, the rail structure The positional relationship detection means can also be configured by a linear position detection sensor that detects the positional relationship of the mounted structure portion with respect to the mounting structure. If comprised in this way, it will become possible to slide an input command generator main body along a rail structure, and there exists an advantage that the position change of an input command generator main body can be performed smoothly.

  The present invention can also be grasped as a new image object input command generation device provided with function adding means for adding a predetermined function to the image display control means. The function adding means adds a function to the image display control means to determine the expression position of the display screen of the image object based on the positional relationship included in the input command and to cause the image object to appear on the display screen from the expression position. It is. With this configuration, an image object can be displayed on the display screen simply by connecting a new image object input command generation device, without preparing the function in advance in the image display control means. become.

  Here, the function adding means may be provided with a function of storing image object data in the image data storage means. In this case, it is not necessary to prepare image data of the image object in advance in the image data storage means.

  In addition, the function adding unit may have a function of causing the image display control unit to create an image object using the image data stored in the image data storage unit. In this case, since existing image data is used, it is not necessary to prepare image data in advance.

  According to the present invention, the input command generated by operating the operation unit of the new image object input command generating device attached to the case includes information on the positional relationship between the display screen and the input command generating device main body. Therefore, the image display control means determines the expression position of the image object on the display screen based on the information related to the positional relationship, and causes the new image object to appear on the display screen. Therefore, according to the present invention, even a user who does not have special knowledge can operate the operation unit of the dedicated new image object input command generation device attached to the case, on the display screen related to the attachment position. A new image object can be easily expressed at the position. In addition, the conventional input device has an advantage that it is possible to conceive a new display method and use method of an image object that cannot be considered.

  As shown in FIG. 3, the image display apparatus according to the present embodiment includes a new image object input command generation apparatus 1 and a notebook personal computer PC. In the embodiment of FIG. 3, the new image object input command generation device 1 is arranged on one side 25 a of the frame portion 25 of the case 23 holding the image display portion 22 (for example, a liquid crystal panel) having the display screen 21 of the personal computer PC. It is attached via the attachment structure. Although a notebook personal computer is used in this embodiment, the present invention is not limited to this. For example, as a matter of course, the new image object input command generating device 1 may be attached to the image display unit of a desktop personal computer employing a cathode ray tube or a liquid crystal panel as the image display unit 22. In the personal computer PC, function realizing means such as image data storage means and image display control means, which will be described later, are configured. The keyboard input unit 26 of the personal computer PC functions as a part of image change command generation means for generating an image change command. The new image object input command generation device 1 and the personal computer PC are communicably connected by a signal transmission means 16 including, for example, a USB code 15.

  FIGS. 1A to 1F show the new image object input command generation device 1 as seen from different directions. Hereinafter, the new image object input command generation device 1 will be described with reference to FIGS. 1 to 3. The input command generator main body 2 is provided with an operation switch 3 and a dial switch 5 that constitute the operation unit 6 shown in FIG. The input command generator main body 2 includes a main body base 2A formed of plastic or the like. The operation switch 3 is mounted on an elastic cover member 3A mounted on the main body base 2A and a circuit board (not shown) attached to the main body base 2A to detect a change in pressure inside the cover member. And a pressure sensor unit (not shown) that is turned on / off or whose output changes. 2A, when the cover member 3A is pushed from the left and right (when picked) and as shown in FIG. 2B, the cover member 3A is pushed from above. Even in this case, the operation switch 3 generates an operation signal. Although not shown, the input command generator main body 2 is provided with an air flow passage for taking air into and out of the cover member 3A. Therefore, when the finger is released from the cover member 3A, the cover 3A returns to its original shape by the elastic restoring force of the material of the cover member 3A. Further, as shown in FIG. 2C, the dial switch 5 is fixed so as to be rotatable with respect to the main body base 2A.

  As shown in FIGS. 1B, 1C, and 1F, an input command is input to one side 25a of the frame 25 of the case 23 of the personal computer PC at the bottom of the main body base 2A of the input command generator main body 2. Elongated attachment members 9a and 9b that constitute an attachment structure for attaching the generator main body 2 are provided. The engaging member 9a for attachment contacts the back surface of the case 23 of the personal computer PC. The mounting engagement member 9a has a curved shape so as to protrude toward the mating mounting engagement member 9b so that a spring force can be generated in a state where the mounting engagement member 9a is mounted on the frame portion 25 of the case 23. is doing. The engaging member 9b for attachment has a shape in which a cross-sectional shape in a direction orthogonal to the longitudinal direction forms an L shape. The attachment member 9b is fitted to the inner edge of the frame 25 surrounding the display screen 21 of the case 23 in a state where the attachment member 9a is in contact with the back surface of the case 23. When the new image object input command generating device 1 is attached to the frame portion 25, the attachment engaging member 9 b is fitted to the inner edge of the frame portion 25, and then the attachment engaging member 9 a is moved along the back surface of the case 23. You can lower it down. In this example, the positional relationship between the new image object input command generation device 1 and the display screen 21 can be changed by sliding the main body base 2 </ b> A along one side 25 a of the frame portion 25. Further, the positional relationship may be changed using the dial switch 5. Note that the structure of the attachment structure portion is not limited to the structure of the present embodiment, and is arbitrary.

  As shown in FIG. 1E, from the front side end of the main body base 2A, a sensor mounting plate 13 to which light receiving elements 11a to 11c made of phototransistors constituting optical marker detecting means are attached. It extends. In the present embodiment, as shown in FIG. 3, the light receiving elements 11 a to 11 c face the upper area of the display screen 21 in a state where the new image object input command generation device 1 is attached to one side 25 a of the frame portion 25. Further, the length dimension of the sensor mounting plate 13 is determined. It should be noted that the sensor mounting plate 13 may be configured such that its length dimension can be adjusted so as to be compatible with image display units of various personal computers.

  In the present embodiment, the light receiving elements 11 a to 11 c read the positional relationship detection marker image 27 displayed along the one side 25 a of the frame portion 25 in the upper region of the display screen 21. As will be described in detail later, in the present embodiment, the display screen 21 and the input command generator main body 2 include the optical marker detection means including the light receiving elements 11a to 11c and the positional relationship detection marker image 27. A positional relationship detecting means for detecting a positional relationship between the two is configured. The position detection marker image 27 is stored in the image data storage unit 29 by the function adding unit 18 described later and displayed on the display screen 21.

  The control system of the present embodiment will be described with reference to a block diagram showing the configuration of the image display apparatus of the present embodiment shown in FIG. The new image object input command generation device 1 includes an operation unit 6, a positional relationship detection unit 12 that detects a positional relationship between the display screen 21 and the input command generation device main body 2, an input command generation unit 14, and a USB code 15. The signal transmission means 16 comprised including the function addition means 18 is provided. On the personal computer PC side, an image display unit 22 having the display screen 21 described above, an image change command generating means 31 including a keyboard switch 26 and a mouse, and a control unit 28 serving as the center of command control The image data storage means 29 and the image display control means 30 are arranged. In the embodiment shown in FIGS. 1 to 3, the operation unit 6 includes the operation switch 3 and the dial switch 5 described above. When the operation unit 6 is operated, the input command generation unit 14 generates an input command including the positional relationship detected by the positional relationship detection unit 12.

  The positional relationship detection means 12 may have any configuration as long as it can detect the positional relationship between the display screen 21 and the input command generator main body 2. In the embodiment shown in FIGS. 1 to 3, the position detection marker image 27 displayed on the display screen 21 is read by the light receiving elements 11 a to 11 c provided on the new image object input command generation device 1 side, and the display screen is displayed. The positional relationship between 21 and the input command generator main body 2 is detected. In the present embodiment, as shown in FIG. 4A, a rectangular image with a gradation in which the right side is the darkest toward the display screen 21 and the color becomes lighter toward the left side is adopted. Yes. That is, the gradation density is set so that the illuminances detected by the three light receiving elements 11a to 11c are clearly different according to the mounting position of the input command generator main body 2 of the new image object input command generator 1. By observing the difference between the output signal values of the three light receiving elements 11a to 11c, the position can be detected with relatively high accuracy. It is also possible to detect the position using only one light receiving element.

  As shown in FIG. 4B or 4C, the position detection marker image 27 may be set in other manners. FIG. 4B is an image in which the rectangular position detection marker image 27b is divided by one diagonal line to form two triangles, with one triangle being black and the other triangle being white. Since the ratio of black and white differs depending on the position, the installation position of the input command generator main body 2 can be known by reading the color using the light receiving element. FIG. 4C shows a circular position detection marker image 27c in which the size of the circle is gradually increased from the right to the left. In this case, a CCD camera may be used as the optical marker detection means. Then, the attachment position of the input command generator main body 2 of the new image object input command generator 1 may be known depending on the size of the circle read by the CCD camera. Note that the position detection marker image 27 can also be configured by setting graphic images such as circles of the same size provided at regular intervals so that the blinking speed varies depending on the display location. In any case, the positional relationship detecting means 12 displays the input command generating device main body 2 of the new image object input command generating device 1 in accordance with the position detecting marker image 27 detected by the optical marker detecting means (11a to 11c). Determine the positional relationship to the screen and generate information about the positional relationship. Information regarding this positional relationship is included in the input command output from the input command generation unit 14 and transmitted to the control unit 28 via the signal transmission means 16. The control unit 28 outputs a predetermined control command to the image display control unit 30 based on the received input signal.

  The function adding unit 18 adds a predetermined function to the image display control unit 30 when the new image object input command generation device 1 is connected to the control unit 28 of the personal computer PC via the signal transmission unit 16. The command is transmitted to the control unit 28 via the signal transmission means 16. The function adding unit 18 according to the present embodiment determines an expression position of an image object display screen, which will be described later, based on the positional relationship included in the input command to the image display control unit 30, and displays the image object from the expression position. A command for adding a function to be developed on the screen 21 is generated. In the present embodiment, since the function adding means 18 is provided, a new image object input command can be obtained without installing a program for executing the above functions in the image display control means 30 in advance on the personal computer PC side. By simply connecting the generator 1 to the personal computer PC, the image object can be displayed on the display screen. The function adding unit 18 also has image data, and has a function of storing new image object data in the image data storage unit 29. The function adding means 18 is realized by a storage medium such as a flash memory incorporated in the new image object input command generating device 1 and a CPU, and when the new image object input command generating device 1 is connected to the personal computer PC. A function is added to the image display control means 30 by automatically installing necessary programs and data in the personal computer PC.

  The image data storage unit 29 stores image data of an image to be displayed on the display screen, such as an image of an image object or a background image. Further, the image display control means 30 displays an image on the display screen 21 based on the image data stored in the image data storage means 29 according to a predetermined display operation mode. Further, when the image change command is input from the image change command generating unit 31, the image display control unit 30 changes the image accordingly. Further, the image display control means 30 displays a new image object on the display screen 21 based on the input command input from the new image object input command generation device 1. The control unit 28 executes various command input processes and image data input / output processes. In the present embodiment, the image display control means 30 includes the display screen 21 and the new image object input command generation device 1 included in the input command input from the new image object input command generation device 1 via the control unit 28. Based on the positional relationship with the input command generator main body 2, an expression position on the display screen 21 of a new image object is determined, and the image object is expressed on the display screen 21 from the expression position.

  According to the present embodiment, even an operator who does not have special knowledge can operate the new image object input command generation device 1 only by operating the operation unit 6 of the new image object input command generation device 1 attached to the case 23. A new image object can be easily expressed at a position on the display screen 21 having a relationship with the mounting position of the input command generator main body 2. Therefore, it is possible to conceive a new display method and use method of an image object that could not be considered in the past.

  If a program for executing the function added by the function adding unit 18 is installed in advance on the personal computer PC side, the function adding unit 18 does not need to be provided in the new image object input command generation device 1.

  FIG. 6 is a flowchart showing an algorithm of a program used when a new image object IG is displayed on the display screen 21 by the image display apparatus of the present embodiment as shown in FIG. First, in step ST1, the attachment position of the input command generator main body 2 is confirmed. In step ST2, it is confirmed whether or not the mounting position of the input command generator main body 2 can be detected. If the attachment position cannot be detected, it is determined that the operation is not ready to be accepted and an error occurs, and the process proceeds to step ST3. If the attachment position can be detected, it is next determined whether or not the operation unit 6 has been operated in step ST4. When there is no operation of the operation part 6, it will be in a standby state and will return to step ST1. If the operation unit 6 has been operated, the process proceeds to step ST5, where the input command generation unit 14 generates an input command together with information on the positional relationship, and based on this, the image display control means 30 displays the display screen in step ST6. The expression position of is determined. In step ST7, as described above, when there is an image change command from the image change command generating means 31, the image is changed according to the command, and the image object IG is displayed on the display screen 21. It will be. If the operation of the operation unit 6 is repeated, the process returns to step ST1 by step ST8 for the number of times operated, and the process ends when the flow check for each operation is completed.

  7A and 7B are diagrams showing an example of the display of the image object IG displayed on the display screen 21. FIG. In this example, the input command generation device of the new image object input command generation device 1 on the one side 25a of the frame portion 25 based on the information on the positional relationship of the input command generation device main body 2 attached to the one side 25a of the frame portion 25. The image object IG is expressed so that the image object IG is blown out from the position where the main body 2 is attached. In the present embodiment, the operation signal from the operation switch 3 is changed according to the difference in pressure between when pressed from the left and right and when pressed from above. When the operation switch 3 is held and pressed from the left and right, the image is changed so as to inflate the image object IG. Further, when the operation switch 3 is pressed from above, the image object IG is separated from the frame portion. The display pattern of such an image object is arbitrary. For example, based on the information on the positional relationship, the position where the image object appears may be expressed such that the image object IG blows out from the other side 25c opposite to the side 25a of the frame 25. In addition, a plurality of image objects IG may be expressed simultaneously from a plurality of locations on a virtual line of the display screen 21 that passes through the attachment position of the input command generation device main body 2. Therefore, the position of the expression location of the image object IG may be set so as to have some predetermined correspondence with the determined positional relationship.

  In the example of FIG. 7, when the operator pushes the operation switch 3 from the left and right, the image object IG is displayed on the display screen 21 of the new image object input command generation device 1 as shown in FIG. The image object IG blows out from the lower position and expands. Thereafter, when the operation switch 3 is pressed from above, the image object IG is cut off from the one side 25a of the frame portion 25 and dropped toward the bottom of the display screen 21, as shown in FIG. 7B. When the image object IG is displayed in this way, it is possible to realize a method for displaying and using an image object that cannot be conceived by a conventional input device, as if the image object IG was injected from a frame portion.

  In the above embodiment, the USB cable 15 is used for signal transmission, but it goes without saying that signals may be transmitted and received wirelessly.

  The position where the new image object input command generation device 1 is installed is not limited to the upper side 25 a of the frame portion 25. Various shapes can be adopted as the shape of the new image object input command generation device 1. FIGS. 8A and 8B are diagrams showing a second embodiment of the present invention. In FIGS. 8A and 8B, the same members as those in the embodiment shown in FIGS. 1 to 7 have the same reference numerals as those shown in FIGS. 1 to 7 plus 100. The description is omitted. In the second embodiment shown in FIGS. 8A and 8B, the position detection marker image 127 is arranged along the right side 125b of the frame portion 125 on the right side of the display screen. The shape of the new image object input command generation device 101 is the pistol shape. In this case, when the trigger (operation unit 106) of the pistol-shaped input command generation device main body 102 attached to one side 125b of the frame portion 125 is pulled, an image showing a situation in which a bullet-shaped image object IG is fired. Is expressed.

  In the above embodiment, the positional relationship detection means 12 is realized by a combination of the position detection marker image and the optical marker detection means, but the configuration of the positional relationship detection means 12 is not limited to this. 9 and 10 are diagrams showing another example of the positional relationship detection means that can be used in the present invention. In FIGS. 9 and 10, the same members as those in the embodiment shown in FIGS. 1 to 7 are given the same reference numerals as those shown in FIGS. 1 to 7 plus 200. Description is omitted. For example, as shown in FIG. 9, marker detection provided in the new image object input command generation device 201 is performed by attaching an adhesive tape 251 on which a position detection marker 227 corresponding to a position detection marker image is printed to a frame 225. You may implement | achieve using the means 211. FIG. Of course, the position detection marker 227 printed on the adhesive tape 251 may be a marker as shown in FIGS. In this embodiment, as shown in FIG. 10, an adhesive tape 251 on which a position detection marker 227 is printed is attached to the upper surface of one side 225a of the frame portion 225, and directly attached to the bottom of the new image object input command generating device 201. The marker may be detected by the marker detection means 211 provided in the above. If the positional relationship detection means is configured in this way, the display screen is not used, and thus it is possible to prevent the degree of freedom of display from being limited.

  Further, as shown in FIG. 11, the positional relationship detection means may be composed of two positional relationship detection sensors 353 and 354 and reflecting plates 358 and 359 provided in the input command generator main body 302. In FIG. 11, the same members as those in the embodiment shown in FIGS. 1 to 7 are denoted by the same reference numerals as those in FIGS. One positional relationship detection sensor 353 includes a light emitting unit 353a and a light receiving unit 353b, and the other positional relationship detection sensor 354 also includes a light emitting unit 354a and a light receiving unit 354b. The two positional relationship detection sensors 353 and 354 are installed at one end and the other end of one side 325a of the frame portion 325. The new image object input command generation device 301 is disposed between the positional relationship detection sensors 353 and 354. With this configuration, the light emitted from the light emitting unit 353a is reflected by the reflecting plate 358 provided in the input command generating device main body 302, and the light receiving unit 353b receives the reflected light. The light emitted from the light emitting unit 354a is reflected by the reflection plate 359 provided in the input command generation device main body 302, and the light receiving unit 354b receives the reflected light. The positional relationship between the input command generator main body 302 of the new image object input command generator 301 and the display screen 321 is derived from the outputs from the light receiver 353b and the light receiver 354b. That is, when the input command generator main body 302 is installed at equal intervals from the positional relationship detection sensors 353 and 354, the light emitting unit emits light and the light receiving unit receives reflected light. Since the time is the same, the positional relationship between the input command generation device main body 302 and the display screen 321 can be detected using the difference in time. Illustration of the cable 315 is omitted.
