  Embodiments in which the present invention is applied to a projector will be described below with reference to the drawings. In addition, the Example shown below does not limit the content of the invention described in the claim at all. In addition, all the configurations shown in the following embodiments are not necessarily essential as means for solving the invention described in the claims.

(First embodiment)
FIG. 1 is a diagram showing a projection situation in the first embodiment. The projector 100 is connected to the pen tablet 30 via a USB cable, connected to the DVD player 40 via an HDMI cable, and connected to the PC 50 via a display cable. The projector 100 generates the image 20 based on the image information from the DVD player 40 or the PC 50 and projects the image 20 onto the screen 10.

  The user can add an illustration, a comment, or the like by drawing the movement locus of the designated position on the image 20 using the pen tablet 30. In the present embodiment, the projector 100 is based on the pointing position information from the pen tablet 30 and the source image included in the image 20 (an image based on input image information) and an additional image (an image indicating a comment or the like by the pen tablet 30). ) Can be moved.

  Next, functional blocks of the projector 100 having such functions will be described. FIG. 2 is a functional block diagram of the projector 100 according to the first embodiment.

  The projector 100 includes an image information input unit 110 that inputs image information indicating a source image from the DVD player 40, the PC 50, and the like, an instruction position information input unit 120 that inputs instruction position information indicating an instruction position from the pen tablet 30 and the like, An update unit 130 that also functions as a data generation unit, a storage unit 140, a determination unit 150 that performs various determinations, an image generation unit 160 that generates various images, and a projection unit 190 that projects images. Has been.

  In addition, the storage unit 140 includes image data 141 indicating the source image and the additional image, state data 142 indicating the display position of the source image and the additional image, movement trajectory data 143 indicating the movement trajectory of the designated position, the additional image, Input data 144 indicating the type of the output device of the source image information when the additional image information is input is stored.

  FIG. 3 is a diagram illustrating an example of the image data 141, the state data 142, and the input data 144 in the first embodiment.

  The items of the image data 141 correspond to, for example, “ID”, “image information”, which is identification information for each type of image information. The items of the status data 142 include, for example, “ID”, “type”, “upper left position” indicating the display position of the region, “width” indicating the width of the region, “height” indicating the height of the region, display “Order” indicating the time relationship, “state” indicating the display state, and the like are applicable. The items of the input data 144 correspond to, for example, “ID”, “type” indicating the type of the output device of the source image information when the additional image information is input.

  For example, in the state data 142, the images are overlaid in the order of background, PC, HDMI, and USB, so the source image from the PC 50 is overlaid on the background image, and an additional image indicating the movement locus is overlaid thereon. become.

  Note that the projector 100 may implement the functions of these units using the following hardware. For example, in the projector 100, the image information input unit 110 is an HDMI terminal (input unit), a D-sub 15pin terminal (input unit), the pointing position information input unit 120 is a USB interface, the update unit 130, and the determination unit 150 are CPUs. The storage unit 140 may be mounted using a RAM, the image generation unit 160 may be mounted using an image processing circuit, and the projection unit 190 may be mounted using a lamp, a liquid crystal panel, a liquid crystal driving circuit, a lens, or the like.

  Further, the projector 100 may implement the functions of the determination unit 150 and the like by reading a program stored in the information storage medium 200. As such an information storage medium 200, for example, a CD-ROM, DVD-ROM, ROM, RAM, HDD, or the like can be applied.

  Next, a procedure for projecting the image 20 by the projector 100 will be described. FIG. 4 is a flowchart showing a projection procedure in the first embodiment.

  In the initial state, the projector 100 receives image information indicating a source image from the PC 50. The image information input unit 110 inputs image information from the PC 50, and the update unit 130 updates the image data 141 indicating the source image (step S1).

  The determination unit 150 determines whether or not the instruction position information from the pen tablet 30 is input based on the information from the instruction position information input unit 120 (step S2). When the instruction position information is input, the determination unit 150 determines whether the movement instruction operation is performed based on the instruction position information and the state data 142 (step S3).

  For example, the determination unit 150 determines that the pen down position of the pen tablet 30 is a predetermined pixel range (for example, 3 × 3 pixels) from the “upper left position” among the areas other than the background in which the “state” is “display”. If it is within, it may be determined that it is a movement instruction operation.

  If it is not a movement instruction operation, the updating unit 130 updates the movement trajectory data 143 and the state data 142 based on the designated position information (step S5). The image generation unit 160 generates an additional image indicating the movement locus based on the movement locus data 143, and updates the image data 141 indicating the additional image (step S6).

  The image generation unit 160 generates an entire image including the source image and the additional image based on the image data 141 and the state data 142, and the projection unit 190 projects the entire image (step S10).

  FIG. 5 is a diagram illustrating an example of the entire image 300 in the first embodiment. When the entire image including the source image 310 is displayed, the user draws an arrow with the pen tablet 30 to project the entire image 300 in which the movement locus 330 is added to the source image 310.

  Note that a rectangular additional image 320 is displayed so as to surround the movement locus 330, but only the movement locus 330 is actually displayed by setting a transparent color for the background of the additional image 320.

  In the case of the pen tablet 30, the coordinates of the pen tablet 30 and the coordinates of the entire image 300 are clearly associated with each other. Further, as shown in FIG. 5, the movement trajectory 330 may overlap the source image 310, and the movement trajectory 330 and the source image 310 may be difficult to see.

  In such a case, the user can move the source image 310 and the additional image 320 by operating the pen tablet 30.

  For example, the user places the pen tip at a position corresponding to the vicinity of the upper left position of the source image 310 in the pen tablet 30 and moves the pen tip downward as it is. Thereby, a so-called drag operation is performed. Note that the movement instruction operation may be, for example, an operation of moving the image after continuing the pen-down state without moving it for several seconds or more within the region of the image to be moved.

  When such an operation is performed, the determination unit 150 determines that the operation is a movement instruction operation, and the update unit 130 updates the state data 142 so that the “upper left position” of the source image 310 is updated ( Step S4).

  In addition, for example, when there is a movement instruction operation in which more than half of the additional image 320 is moved to the outside of the entire image 300, the update unit 130 determines that the additional image 320 is to be erased and determines data of the additional image 320 (this embodiment In the example, data having “ID” “0004”) may be deleted, or “state” of the additional image 320 in the state data 142 may be updated to “non-display”.

  For example, when there is a movement instruction operation, the update unit 130 may update the “order” of the state data 142 so that the movement instruction target image is in the foreground. For example, in the state shown in FIG. 5, when the user moves the source image 310 to the upper end of the entire image 300, the entire additional image 320 is hidden by the source image 310. In this case, the additional image 320 is displayed again when the user moves the source image 310 downward.

  The image generation unit 160 generates an entire image including the source image and the additional image based on the image data 141 and the state data 142, and the projection unit 190 projects the entire image (step S10).

  FIG. 6 is a diagram illustrating an example of the entire image 301 at the time of movement in the first embodiment. For example, when the source image 310 is moved downward, the entire image 301 in which the movement trajectory 330 and the source image 310 do not overlap each other is displayed.

  Further, the determination unit 150 determines whether or not there is a change in the input unit of image information to be applied, that is, so-called source switching (step S7). For example, the source is switched when the input source is changed from PC to HDMI by a user operation or when image information is input to the HDMI terminal while the original source is in the PC state.

  In the case of source switching, the update unit 130 generates the input data 144 and stores it in the storage unit 140 in order to reproduce the moving trajectory 330 being displayed (step S8). For example, when the input source of image information is a PC and the movement locus 330 is being displayed, the update unit 130, as shown in FIG. 3, the additional image 320 (the ID and image information of the additional image 320) and the additional image information. The input data 144 indicating the type (PC) of the output device of the source image information at the time of input is generated.

  When the input source is changed to HDMI, the image generation unit 160 refers to the input data 144 and based on the data whose “type” is “HDMI”, the “type” is “HDMI”. The additional image 320 indicating the movement locus 330 is generated (step S9), and the projection unit 190 projects the entire image including the additional image 320 (step S10).

  The projector 100 determines whether or not to end by turning off the power button or the like (step S11).

  As described above, according to the present embodiment, the projector 100 generates the entire image 301 in which the position of at least one of the source image 310 and the additional image 320 is changed in the case of the movement operation instruction based on the instruction position information. In addition, by generating the entire image 300 indicating the movement locus 330 of the designated position when it is not a movement operation instruction, it is possible not only to add a comment or the like to the image but also to move the position of the comment or the source image 310. Therefore, it is possible to generate a more easily viewable image.

  Further, according to the present embodiment, the projector 100 manages the additional image information for each type of the output device of the source image information, thereby corresponding to the type of the input unit after application according to the change of the input unit. The entire images 300 and 301 showing the added image 320 can be generated.

  In addition, according to the present embodiment, the projector 100 can display the source image 310 and the additional image 320 at a position corresponding to the movement operation instruction by using the state data 142, and thus adds a comment or the like to the image. In this case, an image that is easier to see can be generated.

  In addition, according to the present embodiment, the user can erase or hide the additional image 320 by moving the source image 310 or the additional image 320 while holding the pen of the pen tablet 30. There is no need to press the delete button to delete the additional image 320 or use the PC 50 or remote controller. Thereby, the projector 100 can reduce a complicated operation of the user and make the projector 100 and the like easier to operate.

(Second embodiment)
In the first embodiment, the projector 100 displays the movement locus 330 as it is. However, the projector 100 may perform character recognition on the movement locus 330 and display it as characters.

  FIG. 7 is a functional block diagram of the projector 101 in the second embodiment. The projector 101 includes a character recognition unit 170 that performs character recognition of the movement trajectory 330 in addition to the configuration of the projector 100 described above, and stores character data 145 indicating a character recognition result in the storage unit 140.

  The character data 145 may include attribute data indicating font data for displaying characters, character size, color, and the like. Further, the projector 101 may read the program from the information storage medium 201 and implement functions such as the character recognition unit 170.

  When the determination unit 150 determines that the operation is not a movement instruction operation, the character recognition unit 170 performs character recognition of the movement locus 330 based on the movement locus data 143 and stores character data 145 indicating the character recognition result in the storage unit 140. To do.

  Based on the character data 145, the image generation unit 160 generates an entire image indicating a character string as the additional image 320 when the movement locus 330 is recognized as a character.

  As described above, the projector 101 can perform character recognition of the movement locus 330 and generate and project an entire image with characters added thereto.

(Other examples)
In addition, application of this invention is not limited to the Example mentioned above, A various deformation | transformation is possible. For example, the image generation unit 160 may generate an additional image 320 indicating a pen-shaped cursor or the like at the current designated position portion of the movement locus 330.

  Further, the output device of the indicated position information is not limited to the pen tablet 30 and may be, for example, a mouse, a liquid crystal pen tablet, a touch pad of a notebook PC, or the like. The image information output device is not limited to the DVD player 40 and the PC 50, and may be, for example, a digital video camera, a digital camera, a photo storage, or the like.

  Further, the usage of the projectors 100 and 101 is not limited to the presentation, and may be, for example, an outdoor advertisement, a television program (for example, a weather forecast) or the like.

  The projector 100 is not limited to a liquid crystal projector (transmission type, reflection type such as LCOS), and may be a projector using a DMD (Digital Micromirror Device), for example. DMD is a trademark of Texas Instruments Incorporated.
