DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram of a video projector according to an embodiment of the present invention. A video projector receives an analog video signal from a video playback device such as a DVD player, converts it into digital data, adjusts the image quality, and projects it on a screen. In the figure, a signal input from a video playback device such as a DVD player may be in any format such as a composite signal or an RGB component signal. The input video signal is converted into digital data by the AD converter 11 and becomes video data. This video data is input to the image quality adjustment unit 12. The image quality adjustment unit 12 adjusts the image quality of the video data input from the video playback device based on the image quality adjustment parameter input from the control unit 10. The image quality adjustment parameters include brightness (Brightness), contrast (Contrast), hue (Hue), saturation (Saturation), sharpness (Sharpness), color temperature (Color Temp), and the like. The video data whose image quality has been adjusted by the image quality adjustment unit 12 is input to the frame controller 13. As shown in FIG. 3, the frame controller 13 has a frame buffer, stores one frame of video data input from the image quality adjustment unit 12, and synchronizes this video data with the processing cycle of the optical system 14 at the subsequent stage. Output. The reproduced image is projected on the screen 20 by the light source lamp and the projection lens. The remote control communication unit 15 receives and demodulates an infrared signal transmitted from the remote control shown in FIG. 2 and inputs a code generated by the remote control operation to the control unit 10. The control unit 10 controls the entire apparatus, that is, the AD converter 11, the image quality adjustment unit 12, the frame controller 13, and the optical system 14, and is constituted by a microcomputer.
[0008]
FIG. 2 is an external view of the remote controller 2 attached to the video projector. The remote controller 2 includes four cross-cursor buttons 21 (21u, 21d, 21l, and 21r) including up / down / left / right button switches, a confirmation button 22 provided at the center of the four cross-cursor buttons 21, and a menu window image. A menu button 23 for calling and deleting 50 (menu 50: see FIG. 5) and an escape button 24 for canceling selection of a predetermined area in the menu 50 are provided. This remote controller is used when adjusting the image quality of the video projector 1.
[0009]
FIG. 3 is a block diagram of the frame controller 13. The frame controller 13 includes a processing unit 30 that controls input / output and composition of video data and a frame buffer 31 that stores one frame of video data. During normal reproduction, the video data input from the image quality adjustment unit 12 is written into the frame buffer 31 for each frame, and is output in synchronization with the processing cycle of the optical system 14.
[0010]
When the user calls the menu by operating the remote controller 2, the control unit 10 generates the menu 50 in FIG. 5 and inputs it to the processing unit 30. The processing unit 30 synthesizes this on the video data input from the image quality adjustment unit 12 and inputs it to the optical system 14. Accordingly, at this time, a screen as shown in FIG. The video data of the menu 50 may be buffered separately or may be directly written in the frame buffer 31.
[0011]
The frame controller 13 is smaller than the frame buffer 31 and has a capture memory 32 that can store a part of the frame. The capture memory 32 is used when the user adjusts the image quality (changes the image quality adjustment parameter).
[0012]
Here, in this specification, the adjustment of (image quality) is used as a word representing the video data processing operation performed by the image quality adjustment unit 12 based on the image quality adjustment parameter. This is used as a word representing an image quality adjustment parameter changing operation performed by the above operation.
[0013]
When adjusting the image quality, the user turns on the menu button 23 of the remote controller 2 to call up the menu. At this time, a video playback device such as a DVD player connected to the front stage of the video projector may be paused so that the video is stopped and a still image may be output, or a moving image may be used. When the menu is called, the control unit 10 generates a menu window image 50 as shown in FIG. 5 and inputs it to the frame controller 13. The frame controller 13 synthesizes the menu window image 50 on the video data input from the image quality adjustment unit 12 and outputs it to the optical system 14 to project the synthesized video as shown in FIG. .
[0014]
Here, the menu window image 50 will be described with reference to FIG. Hereinafter, the menu window image 50 may be simply referred to as a menu 50. The menu includes a plurality of pages, and each page includes a tag area 51 as a heading and a setting area 52 for setting parameters corresponding to the page. FIG. 5A shows a state where the tag area 51a of the image quality adjustment page is selected. In this state, the tag area 51a is colored in a different color from the other tag areas so that it stands out. FIG. 5B shows a state where the second parameter Contrast from the top in the setting area of the image quality adjustment page is selected. The selected parameter is colored with a different color from the other parameters to make it stand out, and the selected parameter operation description (Change Picture Contrast) is displayed in the bottom column of the menu 50. Note that Video displayed on the right is an input source name. In the selected parameter column, an arrow 55 indicating a movable direction indicating which cursor button is turned on to move to another area (parameter) is displayed. In the figure, it is possible to move up or down. When the image quality adjustment page is selected, a preview window 53 for displaying a video adjusted according to the image quality adjustment is set on the left side of the menu 50.
[0015]
When the cursor button 21d in the downward direction is turned on twice from the state shown in FIG. 9A, the state changes to the state shown in FIG. In addition, when the right cursor button 21r is turned on in the state of FIG. The image of the setting area of the selected page is displayed in the display area 52 of the setting area.
[0016]
Further, when any one of the tag areas 51 is selected and the upward cursor button 21u is turned on, the moving bar 54 is selected. The moving bar 54 is not normally displayed, but is displayed only when it is selected. Alternatively, it may be displayed all the time and colored to stand out when selected. When any of the cursor buttons 21 is turned on while the moving bar 54 is displayed, the entire menu 50 moves in the direction of the turned-on cursor.
[0017]
In FIG. 3, after the menu 50 is displayed, when the user operates the remote controller 2 to select the image quality adjustment area, the video data input from the image quality adjustment unit 12 at that time is captured in the frame buffer. That is, the video data at that time is held in the frame buffer 31 as video data before adjustment, and writing of video data input thereafter is prohibited to the frame buffer 31.
[0018]
When the user further operates the remote controller to change the image quality adjustment parameter, that is, when the image quality is adjusted, the control unit 10 inputs the image quality adjustment parameter changed by this adjustment to the image quality adjustment unit 12. Then, the video data output from the image quality adjustment unit 12 thereafter has the image quality adjusted by the user's operation. The frame controller 13 does not take this video data into the frame buffer 31. Only the video data of a part of the area is written into the capture memory 32. The video data written to the capture memory 32 is video data corresponding to the area of the preview window 53 provided on the left side of the menu 50. Then, the processing unit 30 synthesizes the preview video data, which is the video data after the change of the image quality captured in the menu 50 and the capture memory 32, on the video data of the entire frame before the change stored in the frame buffer 31. And output to the optical system 14. As a result, the image after the image quality adjustment is displayed in the window before the image quality adjustment, and it is possible to compare how much the image quality has changed, and the user can adjust the image quality while comparing the actual image. can do.
[0019]
The user adjusts the image quality until the desired image quality is obtained, and when the desired image quality is obtained, the confirmation button 22 is turned on (or the image quality adjustment page is exited). Then, confirmation instruction data indicating that the adjustment of the image quality is confirmed is transmitted from the control unit 10 to the processing unit 30. The processing unit 30 resumes the loading of the video data input from the image quality adjustment unit 12 into the frame buffer 31 corresponding to the instruction data so that the entire video becomes an adjusted video.
[0020]
When the user turns on the menu button 23 again, the menu is erased from the screen, and a normal image is output to the optical system 14. Thereafter, the user releases the pause of the video playback device in the previous stage and resumes normal playback so that the video image is projected. In this way, in this apparatus, when the user adjusts the image quality of the image, both the unadjusted image and the adjusted image are projected on the screen 20, so the user can improve the image quality while comparing the two images. It can be adjusted optimally.
[0021]
In this embodiment, the preview video is displayed inside the window provided on the left side of the menu. However, the combination of the video before the image quality adjustment and the preview video after the adjustment is limited to this. Not. For example, the pre-adjustment video may be left in the window 53 of the menu 50, and all the screens other than the menu may be used as the adjusted preview video. Further, as shown in FIG. 4B, the screen is divided into two areas 201 and 202 without using a window, an image before adjustment is displayed in one area 201, and a preview image is displayed in the other area 202. You may do it. Further, there may or may not be a boundary line between the pre-adjustment video and the preview video. In the example of the menu window image of FIG. 5, the boundary line on the left side of the preview window 53 may be eliminated.
[0022]
6 to 8 are flowcharts showing the operation of the control unit 10. This operation indicates a processing operation corresponding to the button operation of the remote controller 2. As described above, the remote controller 2 has the up / down / left / right cross cursor buttons 21, the confirm button 22, the menu button 23, and the escape button 23. When each button is operated, the corresponding operation is executed. When the menu 50 is not displayed, button operations other than the menu button 23 are invalid.
[0023]
When the menu button 23 is operated, this is determined in s1, and the processing of s2 to s5 is executed. In s2, it is determined whether the menu 50 is currently displayed. When the menu 50 is not being displayed, it is assumed that the operation of the menu button 23 is a menu call, and the data of the menu window image 50 is output to the frame controller 13 and displayed on the screen (s3). In the menu 50, the tag area 51a of the image quality adjustment page, which is the upper left tag area, is selected (s4), the area is colored, and the movable direction is displayed (s5). In the case of this image quality adjustment page tag area 51a, there are three possible directions of movement: up (movement bar 54), right (other tag areas), and down (image quality adjustment page setting area 52).
[0024]
On the other hand, if the menu 50 is being displayed when the menu button 23 is displayed, the operation of the menu button 23 instructs the frame controller 13 to delete the menu window image as an instruction to delete the menu. The menu is deleted (s6). If the area selected at that time is the setting area of the image quality adjustment page, the frame controller 13 is instructed to cancel the capture of the video data to the frame buffer 31 (s7), and the normal area is selected. Return to playback.
[0025]
If the cross cursor button 21 is turned on, this is determined in s10, and if the menu screen is displayed (s11), the operations of s12 to s36 are executed. If the moving bar 54 at the top of the menu 50 is selected at that time, the menu 50 is moved on the screen according to the direction of the cursor button that has been turned on (s13). This movement may be performed by the control unit 10 changing the display coordinates of the menu window image with respect to the frame controller 13.
[0026]
If the selected area is other than the moving bar 54, the process proceeds to s14 to determine whether the upper and lower cursor buttons 21u and 21d are turned on or whether the left and right cursor buttons 21r and 21l are turned on (s14). When the upper and lower cursor buttons 21u and 21d are turned on, the area to be selected is moved according to the operation (s15). That is, all the parameter changes in the setting area are performed by the left and right cursor buttons 21r and 21l, and the upper and lower cursor buttons 21u and 21d are exclusively used for moving the area selection. If the movement bar 54 is selected as a result of this movement, the movement bar 54 is displayed so as to be visible (s17). When moving to an area other than the moving bar, the selected area is colored to stand out, and an arrow indicating the direction in which the area can be moved is displayed (s18).
[0027]
If the setting area 52 of the image quality adjustment page is selected as a result of this movement, the video data currently input from the image quality adjustment unit 12 is input to the frame buffer 31 as an unadjusted video to the frame buffer 13. Instruct to capture (s19, s20). If another setting area is selected as a result of this movement, processing corresponding to that area is performed (s21, s22). In addition, when the area selection is moved from the setting area 52 of the image quality adjustment page to the tag area 51a by this movement, the capture of the video before the adjustment is canceled and the frame controller 13 returns to normal video playback. Instruct (s23, s24).
[0028]
If the left and right cursor buttons 21r and 21l are turned on, it is determined whether the tag area 51 is currently selected or the setting area is selected (s30). When the tag area 51 is selected, the tag area of the page next to the operated direction is moved to display the page in the setting area (s31), and the tag area selected by the movement is colored. And an arrow indicating the direction in which the tag area can be moved is displayed (s32). If the setting area is selected when the left and right cursor buttons are turned on, the setting value is changed according to the operation (s33). At that time, the image quality adjustment area is selected, and any one parameter of brightness (Brightness), contrast (Contrast), hue (Hue), saturation (Saturation), sharpness (Sharpness), and color temperature (Color Temp) is selected. Is changed (s34), the changed parameter value is transmitted to the image quality adjustment unit 12 to change the content of the image quality adjustment (s35). If the setting area is other than the image quality adjustment unit, processing corresponding to the area is executed (s36).
[0029]
If the confirm button 22 is turned on, it is determined in s40 and the processes of s41 to s44 are executed. If the setting area 52 of the image quality adjustment page is selected when the confirm button 22 is turned on, the adjustment content at that time is temporarily confirmed, so that it is input from the image quality adjustment unit 12 to the frame controller 13 at that time. The video buffer 31 is instructed to capture again the current video data (s41, s42). As a result, the image quality adjustment content when the confirm button 22 is turned on is taken into the frame buffer 31 as an image before adjustment. If another setting area is selected, processing corresponding to that area is executed (s43, s44). If the selected area is other than the setting area, nothing is done.
[0030]
If the escape button 24 is turned on, this is determined in s45, and the operation from s46 is executed. In this embodiment, the escape button 24 is effective only when the moving bar 54 is selected. For this reason, it is determined whether or not the moving bar 54 is currently selected (s46), and if the moving bar 54 is not selected, nothing is done. When the movement bar 54 is selected, it is determined that the movement of the escape button 24 is completed, and the selection is moved to the tag area selected before moving to the movement bar 54 ( s47). Then, the tag area is colored to stand out, and an arrow indicating the direction in which the tag area can be moved is displayed (s48).
[0031]
Thus, in this embodiment, when the menu 50 is displayed and the setting area 52 of the image quality adjustment page is selected, the pre-adjustment video is displayed on a screen other than the menu 50, and the preview window in the menu 50 is displayed. By displaying the adjusted preview video in 53, it is possible to adjust to the optimum image quality while comparing both.
[0032]
In addition, regardless of which area is selected in the menu 50, the user can perform an appropriate operation by displaying the movable direction with an arrow when moving from that area to another area. It becomes possible. In the embodiment, the arrow is displayed in the selected area. However, an arrow display area may be provided outside the selected area so that the arrow is always displayed in the area. Moreover, you may make it display the arrow of a movable direction in all the areas including the area which is not selected.
[0033]
In addition, since the menu 50 can be moved within the screen, when adjusting the image quality, the menu is moved to an unobtrusive place, or the preview window 53 is moved to the most noticeable place. This makes it possible to display a preview image, and the image quality can be easily adjusted.
[0034]
9 and 10 are diagrams showing another embodiment. In these embodiments, the frame controller 13 includes only the processing unit 30 and the frame buffer 31, and the embodiment of FIG. 9 performs a preview using the function of the control unit 10, and the embodiment of FIG. The preview is performed using the mask function of the processing unit 30.
In FIG. 9, the processing unit 10 captures a partial area of the video data input to the frame controller 13, adjusts the image quality, and feeds this back to the frame controller 13. In this embodiment, the frame controller 13 stores the video data input from the image quality adjustment unit 12 in the frame buffer 31, of which a partial area (area of the preview window 53 of the menu 50) designated by the control unit 10. Video data is input to the control unit 10. The control unit 10 adjusts the video data of this partial area to the image quality adjusted by the user. The control unit 10 stores image quality adjustment parameters that are currently set in the image quality adjustment unit 12, and also receives image quality adjustment parameters that have been changed by the user. Based on this, the control unit 10 adjusts the input video data of the partial area to the image quality changed by the user and feeds it back to the frame controller 13. The frame controller 13 combines the original video data buffered in the frame buffer 31 (pre-adjustment video), video data of a partial area fed back from the control unit 10 (adjusted preview video and menu window image). In this case, the frame controller 13 (processing unit 30) may overwrite the video data fed back from the control unit 10 on the frame buffer 31, and the processing unit without rewriting the frame buffer 31. The images may be combined within 30 and output to the optical system 14.
[0035]
In the case of the above configuration, in the flowcharts of FIGS. 6 to 8, the processing unit 10 uses the video data input from the frame controller 13 based on the user's setting change instead of transmitting the parameter to the image quality adjustment unit 12 in s35. The image quality is adjusted (readjusted) and fed back to the frame controller 13.
[0036]
The above processing is basically performed on a still image, but if the processing of the control unit 10 is fast, it is possible to preview the moving image as it is. Further, in this embodiment, since the processing unit 10 creates a preview image, it is not necessary to directly input the image quality adjustment parameter setting change (adjustment) by the user to the image quality adjustment unit 12, and the setting change can be canceled. Easy. When previewing a moving image as it is, it is not necessary to instruct to capture and release the video in the flowcharts of FIGS. 6 to 8, and the latest video data is always input from the image quality adjustment unit 12 to the frame buffer 31. What is necessary is just to input the video data of the part corresponding to a preview window among writing.
[0037]
In the embodiment of FIG. 10, when the setting area 52 of the image quality adjustment page is selected, the image input at that time is masked by masking areas other than the area of the preview window 53 to the processing unit 30 of the frame controller 13. Capture data as a pre-adjustment video. When the image quality adjustment parameter is changed by remote control operation, the control unit 10 transmits the parameter to the image quality adjustment unit 12. Therefore, the image quality adjusting unit 12 adjusts the image quality of the video data to be input thereafter and inputs it to the frame controller 13, but this new video data is frame buffered only in the portion corresponding to the unmasked preview window 53. 31 is written. Thus, the capture memory 32 can be omitted by directly writing the preview video data into the frame buffer 31.
[0038]
In this embodiment, the level of the items of the menu 50 is two levels of page → parameter. However, as shown in FIG. 11, page (menu 1-5) → submenu (Prm1-5) → parameter There are also three stages. Even in this case, as shown in the figure, when each item (page, submenu, parameter) is selected, the movable direction is displayed by an arrow. In this figure, all the arrows are shown, but actually, only the arrows in the movable direction from the item selected at that time are displayed.
[0039]
In this embodiment, a video projector has been described as an example. However, the present invention is not limited to a video projector, and any processing device that displays a plurality of items such as menus on a screen and allows a user to operate the screen can be used. It can also be applied to various devices.
[0040]
【The invention's effect】
As described above, according to the present invention, by displaying an item whose selection can be moved with an arrow or the like, when the user operates, for example, the parameter is increased or decreased to move or the parameter is increased or decreased. Does not make mistakes such as moving the parameter selection.
