  The control unit 50 includes a CPU, a ROM that stores an operation program executed by the CPU, and a RAM that is used as a work memory. The control unit 50 receives a key operation signal input from the key unit 51 in response to a key operation or a position signal input from the A / D conversion unit 52 in response to the operation of the slide bar 30 (in a predetermined range of the slide bar 30). A control signal corresponding to the position information corresponding to the relative position) is transmitted to the projector device 10 via the Ir transmitter 53.

  The key unit 51 controls an input operation to each key shown in FIG. 3 and notifies the control unit 50 of a key operation signal corresponding to each key operation.

  The A / D converter 52 performs A / D conversion on the signal from the variable resistor that changes in accordance with the slide operation on the slide bar 30 and outputs the signal to the controller 50.

  Next, the operation of the projector apparatus 10 according to the present embodiment will be described with reference to the flowcharts shown in FIGS. FIG. 5 is a flowchart for explaining the operation of the remote controller 29, and FIG. 6 is a flowchart for explaining the operation of the projector device 10.

  Here, a case will be described in which an application program running on a personal computer, for example, a program that executes a process for presentation, executes a process of displaying images of a plurality of pages while switching them in units of pages. In this case, by switching the image to be displayed by the application program of the personal computer, the image signal of this image is output to the projector device 10 and projected onto the screen. In this embodiment, by operating the slide bar 30 provided in the remote controller 29, the operation of the application program on the personal computer can be controlled through the projector device 10 to switch the image projected on the screen. .

  First, the remote controller 29 (control unit 50) sets the maximum value and the minimum value of the voltage value that is changed by operating the slide bar 30 (step A1).

  When a key operation is performed on various keys provided on the remote controller 29 (step A2), the control unit 50 inputs a signal corresponding to the key operated from the key unit 51. The control unit 50 transmits a key operation signal corresponding to the signal input from the key unit 51 to the projector device 10 through the Ir transmission unit 53 (step A3).

  Further, the control unit 50 reads a signal input via the A / D conversion unit 52 (step A4), and a voltage that can be obtained by a change in the voltage value indicated by this signal and the position of the slide bar 30 set in advance. Based on the maximum and minimum values, the current position of the slide bar 30 is calculated (step A5). For example, the position in the movable range of the slide bar 30 can be calculated depending on the relative position of the current voltage value in the range of the maximum value and the minimum value of the voltage.

  Here, when the position of the slide bar 30 has changed since the voltage value was read first, that is, when there has been an operation to change the position of the slide bar 30, the control unit 50 performs the operation of the slide bar 30. A position signal representing the position is transmitted to the projector device 10 via the Ir transmitter 53 (step A7).

  In this way, the remote controller 29 can notify the projector device 10 of information on the position changed by the slide operation on the slide bar 30.

Next, the operation of the projector device 10 will be described.
First, the projector device 10 reads data handled in an application program running on a personal computer, that is, the total number of pages of an image to be projected onto the screen (step B1). Here, the user may input by operating the key / indicator unit 47 provided in the projector device 10, or the user inputs the page number by operating the key to the remote controller 29 and receives it through the remote controller 29. Anyway. Further, a program attached to an application program executed on the personal computer may acquire information on the data file currently being processed from the application program, and may receive the information via the USB cable. In this case, this program needs to be installed in the personal computer in advance so that it can communicate with the projector device 10.

  The controller 44 monitors whether the signal from the remote controller 29 is received by the Ir receiver 48 (step B2). When receiving from the remote controller 29 (step B2, Yes), the control part 44 determines whether the received signal is the key operation signal transmitted by key input operation (step B3).

  Here, when the key operation signal received from the remote controller 29 indicates page feed (step B4, Yes), the control unit 44 sends to the personal computer via the input / output interface 31, the input / output connector unit 21, and the USB cable. A control code (control information) instructing execution of page feed is output (step B5). The control unit 44 converts the control code handled by the application program on the personal computer, that is, the control code input by the key operation on the keyboard in the personal computer, and outputs the control code. Thus, the application program on the personal computer can be controlled by the control code from the projector device 10.

  If the key operation signal received from the remote controller 29 indicates page return (step B6, Yes), the control unit 44 similarly outputs a control code for instructing the personal computer to execute page return. (Step B7).

  When another key operation signal is received, the control unit 44 executes other processing according to the key operation signal (step B8).

  On the other hand, when the control unit 44 determines that the position signal is transmitted from the remote controller 29 by an operation on the slide bar 30 (step B9, Yes), a page corresponding to the position of the slide bar 30 indicated by the position signal is displayed. Calculation is made based on the total number of pages read first (step B10).

  The control unit 44 instructs execution of page switching based on the page calculated according to the position of the slide bar 30 (step B11). Note that the control unit 44 converts a page switching execution instruction into a control code handled by an application program on a personal computer and transmits the control code. For example, if the application program can be controlled by a control code instructing page jump by designating the page, it is converted into the corresponding control code (designated page, page jump) and output, or simply page feed or page return control If control is possible using codes, page feed or page return control codes are continuously output for the number of pages required for page switching.

FIG. 7 is a diagram showing a correspondence relationship between the total number of pages of the file handled by the application program and the position of the slide bar 30.
For example, as shown in FIG. 7A, when the total number of pages is 5, each page corresponds to each of a range of 1/5 of the movable range of the slide bar 30. Thus, by moving the slide bar 30 to a position corresponding to the desired page, it is possible to instruct to switch to the page corresponding to this position.

  Further, when the total number of pages of data handled by the application program is 20, each page corresponds to a range of 1/20 of the movable range of the slide bar 30 in the same manner. Even when the number of pages is large as described above, the pages can be easily switched by simply moving the slide bar 30 to the range (position) in the vicinity of the corresponding page. Therefore, there is no need to instruct page return or page feed for the number of pages from the current display target page to the desired page.

  When the total number of pages is very large, it becomes difficult to reliably specify the position of the corresponding page by the slide bar 30. In such a case, first, the page is switched to the vicinity of the desired page by operating the slide bar 30, and then the page is switched to the desired page by key operation for page advance or page return. As a result, even when the total number of pages is very large, it is easier to switch pages because the number of pages is larger than when switching pages by keying for page advance or page return. Can do.

  The application program of the personal computer controls page switching according to the control code received via the projector device 10. As a result, the image to be displayed is switched to the page designated by the operation of the remote controller 29, and the display data of the image is transmitted to the projector device 10 via the RGB cable and projected onto the screen.

  In this way, the slide bar 30 is provided in the remote controller 29, and the projector device 10 transmits a control code (control information) corresponding to the position of the slide bar 30 changed by an operation on the slide bar 30 to the personal computer. can do. Accordingly, in a predetermined range (all pages) for processing executed on the personal computer, for example, processing for switching and displaying images of a plurality of pages, by designating a position within a predetermined range in which the slide bar 30 is movable. It is possible to control display switching by directly specifying a specific position (page to be displayed).

  In the above description, the slide bar 30 is provided in the remote controller 29. However, for example, an operation element having another form such as a rotary (dial) type may be provided. In the case of a rotary operation element, for example, a rotation range is determined, and a position signal corresponding to a relative rotation position in the rotation range is transmitted to the projector device 10.

  In the above-described configuration, the input operation to the slide bar 30 is detected by the configuration using the variable resistor and the A / D conversion unit 52 in the configuration of the remote controller 29, but other configurations such as a linear encoder are used. It may be used.

  In the above description, the application program for executing the process of displaying a plurality of pages of images while switching them in units of pages is controlled by operating the slide bar 30 via the projector device 10. It is also possible to control various processes executed on the personal computer. For example, it is possible to target various processes such as scrolling of a display image, movement of a cursor, movement of a mouse pointer, and the like that can specify the width of change by a relative position in the entire range.

  Also, a plurality of functions may be controlled by operating the slide bar 30 by combining a plurality of other key operations and operations on the slide bar 30.

  Note that the above embodiment includes inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent elements are deleted from all the constituent elements shown in the embodiment, at least one of the problems described in the column of problems to be solved by the invention can be solved, and described in the column of the effect of the invention.
