(Embodiment 1)
FIG. 1 is a diagram showing the overall configuration of the pointer system according to Embodiment 1 of the present invention. In FIG. 1, the screen 102 reflects and displays the projection image from the projector 104. An image from the personal computer 103 or the VIDEO deck 106 is input as an input image to the projector 104. The pointer 101 is displayed on the screen 102 by coordinate data from the remote controller 105.

  FIG. 2 is a diagram showing a schematic appearance of the remote controller 105 in FIG. 1, which includes the remote controller main body 105, the liquid crystal screen 202, and the touch screen 203, and indicates that the touch pen 203 is used for input to the touch screen 203. .

  FIG. 3 is a diagram showing the internal configuration of the projector and the remote controller. As the internal configuration of the projector 104, video from the VIDEO deck or the personal computer is input by the video input means 304. The input image is resized (changed in size) by the image resizing unit 302 to a size that matches the image projecting unit 312. The resized video is input to the video output unit 303, the output from the video output unit 303 is captured by the video capturing unit 307, the captured video is stored by the captured video storage unit 311, and the stored video is resized by the captured video The image is resized to a size that can be displayed on the liquid crystal screen 202 by the means 309 and passed to the wireless video transmission means 310. The wireless video transmission unit 310 establishes wireless communication with the remote controller and transmits the resized captured image to the remote controller 105. The video transmitted from the projector 104 is received by the wireless video receiving means 314 in the remote controller 105, transferred to the received video storage means 315, and displayed on the liquid crystal screen 202 of the pointing video display means 317 by the liquid crystal screen display means 316. With the configuration so far, when projected by the projector 104, the same image is displayed on the liquid crystal screen of the remote controller 105.

  Next, an operation for displaying a pointer on a projected image will be described. First, the touch screen 203 of the pointing image display unit 317 of the remote controller 105 is touched with the touch pen 204 in FIG. 2, the coordinates are detected by the input coordinate detection unit 320, passed to the infrared command transmission unit 321, and transmitted to the projector. . The remote controller 105 also has a function of instructing the projector 104 to perform input switching by using the button SW 322 and the pressed button determining unit 323, and this instruction is also transmitted to the projector 104 by the infrared command transmitting unit 321. In the projector 104, the command transmitted from the infrared command transmission unit 321 of the remote controller 105 is received by the infrared command reception unit 305. The received command is passed to the video input means 304 if it is an input switching command, and is passed to the pointer display coordinate setting means 306 if it is a pointing coordinate. The pointer display coordinate setting means 306 determines the coordinates for displaying the pointer 101 on the projected image, the coordinates are passed to the pointer composition means 308, the pointer is synthesized with the image output from the image output means 303, and the image projection means. The image is input to 312 and projected on the screen. With the configuration so far, the coordinates of the projected image can be specified directly by touching the touch screen 203 arranged on the liquid crystal screen 202 of the remote controller 105, and the pointer is displayed at the position to be pointed to by the projected image. be able to.

  Further, since the command for designating the position of the pointer is not transmitted unless the touch screen 203 is touched, the displayed pointer does not shake.

(Embodiment 2)
FIG. 4 is a diagram illustrating an internal configuration of the projector and the remote controller in the projector, the projector remote controller, and the pointer system according to the second embodiment of the present invention. 4, the same components as those in FIG. 3 in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The captured video resizing unit 309 in the projector 104 in FIG. 3 in the first embodiment is omitted, and the captured video is directly sent to the wireless video transmission unit 310. Further, in the remote controller 105, a received image resizing unit 401 is disposed between the received image storage unit 315 and the liquid crystal screen display unit 316 so that the same image as the projected image of the projector 104 is resized on the remote controller 105 side. ing.

  According to this configuration, since the configuration of the projector 104 can be simplified, the main body size of the projector can be reduced.

(Embodiment 3)
FIG. 5 is a diagram showing a configuration when a pointing device is connected to the remote controller in the projector, the projector remote control, and the pointer system according to the third embodiment of the present invention. FIG. 6 is a diagram showing the internal configuration of the projector remote control in the present embodiment. The projector has the same configuration as that in FIG.

  According to this configuration, the pointing device 501 such as a mouse connected to the remote controller 105 notifies the pointer input coordinate setting unit 601 of the remote controller 105 of the pointer movement distance, and the pointer input coordinate setting unit 601 notifies the liquid crystal screen of the remote controller 105. The pointer composite coordinates and the pointer coordinates are notified to the infrared command transmission means 321, and the pointer composition means 602 displays a pointer (not shown) on the liquid crystal screen 202. With this configuration, by moving a pointer (not shown) displayed on the liquid crystal screen 202 of the remote controller 105 with the pointing device 501, the coordinates are detected by the input coordinate detecting means 320 and passed to the infrared command transmitting means 321 to be projected by the projector. 104 is transmitted. Thereby, the pointer position on the projection screen can be designated, and the pointer can be displayed at the position desired to be pointed by the projected image.

  As described above, the projector and the pointer system according to the present invention can capture a still image from a personal computer and a VIDEO image such as a VIDEO deck or a DVD player in real time by the image capturing means, and transmit the captured image to the remote controller in real time. Therefore, the same image as the image projected on the screen is always displayed on the remote control. The speaker can point the desired position by intuitively pointing the same image as the projected image displayed on the remote control, and the pointer is displayed directly at the indicated position. Since the troublesomeness of moving can be eliminated and the pointer position is sent to the projector only when the LCD screen is pointed, when not pointing, the pointer is displayed at the previously pointed position. The pointer does not sway when the speaker's arm swings.
