In this case, the information processing means 180 (including the function of the movement signal addition means) adds the movement signal received from the other computer device to the position of the set pointer image 16 to generate a movement signal. It has a function. In this case, the information processing unit 180 (including the function of the pointer video position setting unit) sets the position of the first pointer video 16 based on the added movement signal, and points to the received specific computer device. A process of setting the position of the second pointer image 16 is performed based on the movement signal of the device, and an image including a plurality of pointer images is projected at least at the set position.

  Further, the pointer projection instruction acquisition unit such as the information processing unit 180 acquires a predetermined amount of movement signal while acquiring the pointing device button pressing signal from a specific computer device, and then releases the pointing device button pressing. When the signal is acquired, the pointing device movement signal received from the specific computer device is used to project and move the pointer image for the pointing device, and the pointer image is not projected independently. It has a function to switch between.

  Next, operation event processing executed by the computer device 800 and the projection device 100 will be described with reference to FIG.

  FIG. 4 is a flowchart of the operation event transmission process executed by the information processing unit 880 of the computer apparatus 800 and the operation event process executed by the information processing means 180 of the projection apparatus 100.

  When the user operates the input unit 170 or the like provided in the projection device 100 to instruct the projection of the image, the processing executed by the information processing unit 180 of the projection device 100 is step S152 “projection, pointer mode. Proceeding to the processing of “setting” (hereinafter abbreviated as S152), the projection mode and pointer mode are set.

  Here, the projection mode to be set includes setting of a plurality of video display modes in which a plurality of videos acquired from a plurality of computer devices are arranged in the projection image 27 projected by the projection apparatus 100. When the projection mode is determined, the RAM 181 stores various setting information such as the resolution of the video received from the computer device 800, the resolution of the projection image 27, and the number of videos arranged in the projection image 27. In addition, the pointer mode set here includes setting of pointer attributes such as the display color, shape, locus, and movement of the pointer image to be projected.

  When the projection mode and the pointer mode are set in S152, the initialization information including the mode setting information is stored in the storage unit such as the RAM 181 and the communication unit such as the wireless transmission / reception unit 161 or the wired transmission / reception unit 162 of the projection apparatus 100. To one or a plurality of computer devices 800 connected for communication.

  Then, the process executed by the information processing unit 180 of the projection apparatus 100 proceeds to S154 “Set the drawing coordinate of the pointer video to the center of the screen”, and uses the number of pixels of the projection image 27 as the initial value of the projection position of the pointer video 16 ( Set half of the vertical and horizontal values. For example, when the number of pixels of the projection image 27 is 1280 × 1024 dots, Xp = 640 and Yp = 512 are substituted as initial values of the projection position (Xp, Yp) of the pointer video 16 and stored in the RAM 181. .

  On the other hand, the computer device 800 receives initialization information including mode setting information via the communication means such as the wireless transmission / reception means 861 or the wired transmission / reception means 862 in S102 “projection, pointer mode setting”, and stores the storage means such as the RAM 881. The projection mode and the pointer mode are set.

  Then, the information processing unit 880 does not pass the event information such as the pointing device movement signal (ΔX, ΔY) acquired from the mouse 830 or the like, the button pressing signal and the pressing release signal to the application program, and the wireless transmitting / receiving unit 861. Alternatively, a process of setting a mode for transmitting to the projection apparatus 100 via a communication unit such as the wired transmission / reception unit 862 is performed. The wheel scroll information acquired from the mouse 830 may be passed to the application program of the computer device 800 without being transmitted to the projection device 100.

  In the above description, the projection mode and the pointer mode are input on the projection apparatus 100 side. However, the projection mode and the pointer mode are set on the computer apparatus 800 side. May be. In this case, initialization information including mode setting information is transmitted from the computer device 800 to the projection device 100, and the projection mode and pointer mode setting processing is performed by each device.

In addition, the computer devices 800A to 800D may display information about the pointer shape and the pointer display color to the projection device 100 side to display the unique pointer video 16. Further, a default pointer image 16 may be determined on the projection apparatus 100 side in advance as the pointer shape and pointer display color. When the projection mode and the pointer mode are set in S102, the processing executed by the information processing means 880 Proceeds to the next determination of S104 “There is a pointing device operation?”, Checks the buffer of the pointing device interface 852 by interruption or polling, and waits for the movement signal of the pointing device, the button press signal or the press release signal to be stored. Process.

  If it is determined that the pointing device movement signal, the button pressing signal, or the pressing release signal is stored in the buffer of the pointing device interface 852, the process proceeds to the next step S106 “Acquire pointing device operation information”.

  In step S <b> 106, the information processing unit 880 acquires the movement signal of the pointing device, the button pressing signal, and the pressing release signal stored in the buffer of the pointing device interface 852 via the bus 899. Then, a process for reading the pointer attributes such as the display color, shape, locus, and movement of the pointer image 16 stored in the RAM 881 is performed, and the process proceeds to the next step S112.

  In step S112, the information processing unit 880 performs processing for creating transmission data of event information including the operation information of the pointing device acquired in step S106.

  FIG. 5 shows an example of the structure of the event information created in S112.

  As shown in FIG. 5, the event information includes an X-direction movement signal and a Y-direction movement signal that indicate the movement amounts of the pointing device in the X direction and the Y direction. Further, the computer apparatus identification information and the pointing device movement signal may be associated with each other according to the necessity of the processing executed by the projection apparatus 100, or the display color information of the pointer image, the movement signal of the pointing device, and the pointer shape Information and pointing device movement signal, computer device identification information and button pressing signal and pressing release signal of pointing device or keyboard, etc., and whether or not the computer device identification information and pointer image are projected and moved independently Information or the like may be associated.

  When the creation of event information transmission data is completed in S112, the process proceeds to the next S114 "Event information transmission", and the information processing means 880 outputs an address and a transmission command to the wireless transmission / reception means 861 or the wired transmission / reception means 862. At the same time, the event information is output via the bus 899 and output. Then, the computer apparatus 800 performs processing for transmitting event information to the projection apparatus 100 via the wireless transmission / reception means 861 or the wired transmission / reception means 862. When the transmission of the event information ends, the processing executed by the information processing means 880 proceeds to the next determination of S116 “Projection end?”.

  In S116, the information processing unit 880 checks the buffer of the wireless transmission / reception unit 861 or the wired transmission / reception unit 862, and checks whether the projection end command has been transmitted from the projection apparatus 100 or the buffer of the input interface 871. It is determined whether a projection end command has been acquired from the user.

  If it is determined in S116 that the projection end command has been acquired, the processing executed by the information processing means 880 proceeds to the next S118 “End processing”, and it is determined that the projection end command has not been acquired. In the case, the process returns to S104.

  In step S118, the information processing unit 880 performs processing for canceling the setting of the projection mode and the pointer mode in response to the acquisition of the projection end command. Then, the information processing means 880 sets a normal use mode in which event information such as a pointing device movement signal (ΔX, ΔY) acquired from the mouse 830 or the like, a button press signal, and a press release signal is passed to the application program. Then, the process proceeds to the next S120 “END”, and the operation event transmission process routine is terminated.

  On the other hand, the information processing unit 180 of the projection apparatus 100 receives the event information of the pointing device from the one or more computer apparatuses 800 via the wireless transmission / reception unit 161 or the wired transmission / reception unit 162 in S156 “Receive event information?”. Wait for it to do.

  If the event information received from the computer device 800 is not stored in the buffer of the wireless transmission / reception unit 161 or the wired transmission / reception unit 162, the process of S156 is executed again. Also, if it is determined that the event information transmitted by the computer device 800 is stored in the buffer of the wireless transmission / reception unit 161 or the wired transmission / reception unit 162, the preset display color of the pointer video, the pointer video The shape, the locus of the pointer image, the movement of the pointer, etc. are acquired from the storage means such as the RAM 181 or the ROM 183, and the process proceeds to the next step S160 “Set pointer image position (Xp, Yp)”.

  In S160, the information processing unit 180 acquires the position (Xp, Yp) of the pointer image 16 currently set from the RAM 181 and uses the pointing device movement signal (ΔX, ΔY) acquired in S156 to perform the pointer. A process of setting the position of the image 16 (Xp + ΔX → Xp, Yp + ΔY → Yp) is performed.

  Then, in the next S162 “project projection image and pointer video”, the information processing means 180 displays an instruction to project the one or more pointer videos 16 specified in S160 at the set position together with the video. The data is output to the processing unit 196. Then, for example, as shown in FIG. 1, the pointer video 16 is displayed on the projection image 27. The pointer video 16 may be a pointer video unique to the computer device 800A, for example, or may be a shared pointer video in which one pointer video 16 is moved based on movement signals received from a plurality of computer devices 800A to 800D. Good. When the shared pointer image 16 is moved, the movement signals (ΔX, ΔY) are obtained by adding the movement signals of the plurality of pointing devices acquired from the plurality of computer apparatuses 800A to 800D to the set position of the pointer image 16. And the shared pointer video 16 is moved.

  In next S164 “projection end?”, The information processing unit 180 checks the buffer of the wireless transmission / reception unit 161 or the wired transmission / reception unit 162, and a projection end command has been transmitted from the computer device 800 or the input unit 170. The interface buffer is examined, and it is determined whether or not a projection end command has been obtained from the user.

  If it is determined in S164 that a projection end command has been acquired, the projection end flag of the computer device 800 that has acquired the projection end is set, and the process proceeds to the next determination in S166 "Is there a video signal?" . If it is determined that the projection end command has not been acquired, the process returns to S156.

  In next step S166, the information processing unit 180 inquires of the image processing unit 196 whether or not the video signal input unit 151 has acquired the video signal. If the information indicating that the video signal input means 151 is receiving the video signal is acquired from the image processing means 196, the processing executed by the information processing means 180 returns to S156 and the projection is continued. Further, when the information indicating that the video signal input unit 151 is receiving the video signal is not acquired from the image processing unit 196, or the projection end flags of all the computer apparatuses 800 that are in communication connection are set. If YES, the processing executed by the information processing means 180 proceeds to “end processing” in S168.

  In S168, the information processing unit 180 performs processing for outputting information for ending the projection of the projection image 27 to the lamp control circuit 195, the image processing unit 196, and the like, and ends the projection. Then, the process proceeds to the next S170 “END”, and the operation event processing routine is terminated.

  Next, another embodiment of the operation event process executed by the computer apparatuses 800A to 800D and the projection apparatus 100 will be described with reference to FIG.

  6 shows an operation event transmission process executed by the information processing means 880 of the computer device 800 when projecting and moving a plurality of pointer images having different display colors or shapes for each of the computer devices 800A to 800D. 4 is a flowchart of operation event processing executed by the information processing means 180 of the apparatus 100. Note that description of the same processing as that shown in FIG. 4 is omitted.

  When the user operates the input unit 170 or the like provided in the projection device 100 to instruct the projection of the image, the processing executed by the information processing unit 180 of the projection device 100 is step S152 “projection, pointer mode. Proceeding to the “setting” process, the projection mode and the pointer mode are set.

  Here, the projection mode to be set includes setting of a plurality of video display modes in which a plurality of videos acquired from a plurality of computer devices are arranged in the projection image 27 projected by the projection apparatus 100. When the projection mode is determined, the RAM 181 stores various setting information such as the resolution of the video received from the computer devices 800 </ b> A to 800 </ b> D, the resolution of the projection image 27, and the number of videos arranged in the projection image 27. The pointer mode set here includes setting of pointer attributes such as the number of pointers to be projected, the display color, shape, locus, and movement of the pointer video.

  The processing of S152 to S154 and S102 to S106 is the same as the processing described in FIG.

  When the information processing means 880 acquires the movement signal of the pointing device, the button pressing signal, and the pressing release signal via the bus 899 in S106, the process proceeds to the next S108 "pointer video designation mode?"

  In S108, the information processing means 880 determines whether or not the set pointer mode is a mode for designating pointer attributes such as the display color, shape, locus, and movement of the pointer video. If the mode for specifying the pointer attribute is not set, the process branches to the process of S112 “transmission data creation”.

  If the mode for specifying the pointer attribute is set, the process proceeds to S110 “Get pointer attribute”, and pointers such as the display color, shape, locus, and motion of the pointer video 16 stored in the RAM 881 are displayed. Process to read the attribute. Then, the process proceeds to the next step S112.

  In S112, the information processing unit 880 performs processing for creating transmission data of event information in which the operation information of the pointing device acquired in S106 and the computer device identification information for specifying the computer devices 800A to 800D are associated with each other.

  The event information created here is, for example, the information shown in FIG. 5, and includes computer device identification information and a pointing device movement signal, pointer image display color information and pointing device movement signal, or pointer shape information and pointing device information. Associated with the movement signal.

  Henceforth, since the process of S112-S120 which computer apparatus 800A-800D performs is the same as the process shown in FIG. 4, description is abbreviate | omitted.

  On the other hand, the information processing unit 180 of the projection apparatus 100 receives the event information of the pointing device from one or a plurality of computer apparatuses 800A to 800D via the wireless transmission / reception unit 161 or the wired transmission / reception unit 162 in S156 “Event information received?”. Waiting to receive is performed.

  If the wireless transmission / reception unit 161 or the wired transmission / reception unit 162 has not received event information from the computer devices 800A to 800D, the process of S156 is executed again. If the wireless transmission / reception unit 161 or the wired transmission / reception unit 162 determines that the event information has been received from the computer devices 800A to 800D, the next S158 “pointer video identification (display color, shape, locus, operation, etc.) The process proceeds to.

  In step S158, the information processing unit 180 analyzes the event information and performs processing for specifying the display color of the pointer video, the shape of the pointer video, the locus of the pointer video, or the operation of the pointer.

  For example, when the computer device that has transmitted the movement signal of the pointing device is set to a mode that displays a pointer image having a different display color or pointer image shape, the computer device identification information received from the computer devices 800A to 800D The pointer attribute corresponding to is specified. When pointer information such as the display color of the pointer video or the shape of the pointer video is received from the computer devices 800A to 800D, the received pointer attribute is specified.

  Then, a process of associating a pointer attribute such as the display color or shape of the specified pointer image with the acquired movement signal of the pointing device is performed, and the next S160 “sets pointer image position (Xp, Yp)” Proceed to processing.

  In S160, the information processing unit 180 acquires the position (Xp, Yp) of the pointer image 16 having the corresponding display color or shape from the RAM 181 and uses the movement signal (ΔX, ΔY) of the pointing device acquired in S158. Thus, processing for setting the position of the pointer video 16 (Xp + ΔX → Xp, Yp + ΔY → Yp) is performed.

  In the above-described embodiment, the embodiment has been described in which the relative movement amounts (ΔX, ΔY) are acquired from the computer devices 800A to 800D and the position of the pointer image 16 is set. However, the pointer images are displayed from the computer devices 800A to 800D. The absolute position (Xp, Yp) of 16 may be acquired, and the projection apparatus 100 may set the position of the pointer image 16.

  Then, in the next S162 “project projection image and pointer video”, the information processing means 180 gives an instruction to project the pointer video 16 of the display color or shape specified in S160 to the set position together with the video. The image is output to the image processing unit 196. Then, a plurality of pointer images 16 and 16A are displayed on the projection image 27 as shown in FIG.

  FIG. 7 is a diagram showing another configuration of the projection system including the projection apparatus according to the embodiment of the present invention.

  As shown in FIG. 7, the projection system 10 includes a plurality of projection images 27A to 27D generated using a plurality of video signals received from a plurality of computer devices 800A to 800D in one video (projection image 27). Arranged and projected.

  In addition, the projection system 10 projects pointer images 16 and 16A that can be moved independently based on the movement signal of the pointing device received from the plurality of computer apparatuses 800A to 800D. The pointer video 16 may be a pointer video unique to the computer device 800A, for example, or may be a pointer video shared by the computer devices 800A to 800C. When the shared pointer video 16 is moved, a movement signal is generated by adding the movement signals of the plurality of pointing devices acquired from the plurality of computer apparatuses 800A to 800C to the set position of the pointer video 16 to share the movement. The pointer image 16 is moved.

  Next, a pointer video display color table that associates a plurality of display colors of a pointer video with a plurality of computer apparatuses 800A (PC1) to 800D (PC4) will be described with reference to FIG.

  FIG. 8 is a diagram showing an example of the structure of a display color table for pointer video stored in the RAM 181.

  For example, if event information that associates the computer device identification information with the movement signal of the pointing device is received from each of the computer devices 800A (PC1) to 800D (PC4) in S158, the display color of the specified pointer image is displayed. (One form of pointer attribute) and the movement signal PC1 (ΔX, ΔY) to PC4 (ΔX, ΔY) of the pointing device are associated and stored in the RAM 181.

  In S160, the information processing means 180 refers to the table shown in FIG. 8, and the red pointer image is the movement signal PC1 (ΔX, ΔY), the blue pointer image is the movement signal PC2 (ΔX, ΔY), The position of the pointer image is set using the movement signal PC3 (ΔX, ΔY) for the green pointer image and the movement signal PC4 (ΔX, ΔY) for the cyan pointer image.

  In this manner, pointer images having different display colors can be projected and moved for each of the plurality of computer apparatuses 800A to 800D.

  Next, a pointer video shape table that associates a plurality of pointer video shapes with a plurality of computer apparatuses 800A (PC1) to 800B (PC2) will be described with reference to FIG.

  FIG. 9 is a diagram illustrating an example of the structure of a pointer video shape table stored in the RAM 181.

  For example, when event information that associates the computer device identification information with the movement signal of the pointing device is received from the computer devices 800A (PC1) to 800B (PC2) in S158, the shape of the specified pointer video (pointer) One form of the attribute.) And the movement signal PC1 (ΔX, ΔY) to PC2 (ΔX, ΔY) of the pointing device are associated with each other and stored in the RAM 181.

  In S160, the information processing means 180 refers to the table shown in FIG. 9, and the arrow pointer image is the movement signal PC1 (ΔX, ΔY), and the hourglass pointer image is the movement signal PC2 (ΔX, ΔY). ) Is used to set the position of the pointer image.

  In this way, pointer images having different shapes can be projected and moved for each of the plurality of computer apparatuses 800A to 800B.

  Next, the processing after S164 “Projection end?” Shown in FIG. 6 will be described.

  In step S164, the information processing unit 180 checks the buffer of the wireless transmission / reception unit 161 or the wired transmission / reception unit 162, and checks whether the projection end command has been transmitted from the computer devices 800A to 800D or the interface buffer of the input unit 170. Then, it is determined whether or not a projection end command has been acquired from the user.

  If it is determined in S164 that the projection end command has been acquired, the projection end flag of the computer apparatuses 800A to 800D that acquired the projection end is set and associated with the corresponding computer apparatus identification information. A process for erasing the pointer video is performed. Then, the process proceeds to the next determination of S166 “Is there a video signal?”. If it is determined that the projection end command has not been acquired, the process returns to S156.

  In next step S166, the information processing unit 180 inquires of the image processing unit 196 whether or not the video signal input unit 151 has acquired the video signal. If the information indicating that the video signal input means 151 is receiving the video signal is acquired from the image processing means 196, the processing executed by the information processing means 180 returns to S156 and the projection is continued.

  Further, when the information indicating that the video signal input unit 151 is receiving the video signal is not acquired from the image processing unit 196, or the projection end flags of all the computer apparatuses 800A to 800D connected through communication are displayed. If it is set, the processing executed by the information processing means 180 proceeds to S168 “end processing”.

  In S168, the information processing unit 180 performs processing for outputting information for ending the projection of the projection image 27 to the lamp control circuit 195, the image processing unit 196, and the like, and ends the projection. Then, the process proceeds to the next S170 “END”, and the operation event processing routine is terminated.

  Next, another embodiment of the operation event process executed by the computer apparatuses 800A to 800D and the projection apparatus 100 will be described with reference to FIG.

  FIG. 10 is a flowchart of processing that enables switching between a mode in which a dedicated pointer video is projected and a mode in which a shared pointer video is projected for each of a plurality of computer apparatuses 800A to 800D. Of the processes shown in FIG. 10, a process different from the process shown in FIG. 6 is S157 “pointer video separation / merging process” executed on the projection apparatus 100 side. Therefore, the same processes as those shown in FIG. 6 are denoted by the same step numbers and description thereof is omitted.

  When the information processing unit 180 of the projection apparatus 100 acquires the event information in S156, the processing executed by the information processing unit 180 proceeds to the next subroutine of S157, and executes the processing of S202 “Get pointer list” shown in FIG. To do.

  FIG. 11 is a diagram showing a subroutine of pointer video separation and merging processing executed by the information processing means 180 of the projection apparatus 100.

  When the processing executed by the information processing unit 180 proceeds to S202, the information processing unit 180 refers to the RAM 181 and acquires a pointer video list. FIG. 12 shows an example of the pointer video list acquired here.

  FIG. 12 shows pointer video identification information for specifying a pointer video, computer device identification information for specifying a computer device for acquiring a movement signal for moving each pointer video, and a coordinate value of a projection position of each pointer video. It is a figure which shows the Example of the pointer image | video list memorize | stored in association.

  When the pointer video list is acquired in S202, the processing executed by the information processing means 180 proceeds to the determination of S204 "Switch the pointer video projection mode?" In S202, when the information to switch the projection mode of the pointer video is acquired from the user, the process branches to the determination of S206 "Is there a dedicated pointer video?" If information indicating that the pointer video projection mode is to be switched has not been acquired from the user, the process proceeds to S214 “Is there a dedicated pointer video?”.

  As an input method of information to switch the projection mode of the pointer image acquired from the user in S202, a method of inputting by operating a specific switch provided in the input unit 170 of the projection apparatus 100, the user A method of operating and inputting the keyboards of the computer devices 800A to 800D being operated, a method of inputting predetermined information to the pointing device by the user, and the like can be given.

  In this embodiment, since the user operates the mouse 830 connected to the computer devices 800A to 800D, a method of inputting information for switching the projection mode of the pointer video using the mouse 830 will be described. .

  For example, when the information processing unit 180 acquires a right button press signal of the mouse 830 connected to a specific computer device 800A to 800D as event information, the right button press specific to the specific computer device 800A to 800D is pressed. Set the flag. Further, when the right button press release signal of the mouse 830 is received, the right button press flag is reset.

  Next, the information processing means 180 is in a state in which a right button pressing flag unique to the specific computer devices 800A to 800D is set (a state in which a button pressing signal of the pointing device is acquired from the specific computer devices 800A to 800D) In this case, a predetermined amount of movement signal (for example, 100 pulses) is acquired from the specific computer devices 800A to 800D, and then a right button press release signal of the mouse 830 is acquired from the specific computer devices 800A to 800D. Using the movement signal of the mouse 830 received from the specific computer devices 800A to 800D, the pointer image 16 of the mouse 830 of the specific computer devices 800A to 800D is projected and moved independently, and the pointer Video 16 is projected independently It is possible to switch between stateless.

  In S206, the information processing unit 180 refers to the pointer video list acquired in S202, and the pointer video identification information or the computer device identification information included in the event information acquired in S156 is the dedicated pointer video 16. It is determined whether it is registered as. If the dedicated pointer video 16 is registered, the process proceeds to S208 “Delete pointer information from pointer video list”. On the other hand, if the dedicated pointer video 16 is not registered, the process proceeds to S210 “Register dedicated pointer information in the pointer video list”.

  In S208, the information processing means deletes the dedicated pointer information associated with the pointer video identification information or the computer device identification information included in the event information acquired in S156 from the pointer video list acquired in S202. Perform the process. Then, the process proceeds to the next S224 “update pointer video list”.

  On the other hand, in S210, the information processing means 180 performs processing for registering dedicated pointer information associated with the pointer video identification information or the computer device identification information included in the event information acquired in S156, and then in the next S212. Proceed to the process of “setting the coordinates (Xp, Yp) of the dedicated pointer”. Then, for example, as the initial value of the projection position of the dedicated pointer, the initial value of the projection position (Xp, Yp) is substituted so that the dedicated pointer video 16 is projected at the center of the projection image 27 and stored in the RAM 181. Then, the process proceeds to S224.

  For example, in the example shown in FIG. 12, the pointer image to be moved based on the movement signal received from the PC 3 is a pointer image having a white arrow shape shared with the PC 1, but information indicating that the projection mode of the pointer image of the PC 3 is switched. If acquired, new pointer information dedicated to the PC 3 is registered as shown in FIG. FIG. 13 is a diagram showing a state in which pointer information of a red arrow dedicated to PC 3 is registered in the pointer video list shown in FIG.
