Therefore, even a user who has little knowledge about the function can intuitively understand the function to be operated.
When the two-screen display mode is selected, one of the screens is used as a video adjustment screen and the viewing video is displayed on the other screen, so that the video being viewed can be continuously viewed even during the video adjustment operation.
If the effects of the function of each menu item of video adjustment are known, the video adjustment function installed in the television can be used appropriately by the user, and the video life can be further enjoyed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an example when the present invention is applied to a television receiver. The control unit 10 that controls various functions provided in the television receiver 1 receives a signal from an operation unit or a remote control reception unit 11 generated by a user's key operation. The television broadcast signal from the tuner 12 selected by the user's selection is detected as a video signal by the video intermediate frequency / detection circuit 13, and the detected video signal or the video signal input from the external input terminal is a video signal. The signal is input to the Y / C separation circuit unit 15 via the selector 14. The video signal input to the Y / C separation circuit unit 15 is separated into a luminance signal and a color difference signal, then converted to digital data by the A / D conversion unit 16, and input to the main screen video processing circuit unit 17.
The main screen image processing circuit unit 17 can display the viewing image on one of the two divided screens when a predetermined process for color image data and a later-described two-screen display mode are selected to display the viewing image. To perform compression processing. The image adjustment image generation unit 18 generates a moving image or a still image for explaining the function of each adjustment item, and a function explanation image corresponding to the selected item is generated by a two-screen insertion circuit unit according to a command signal from the control unit 10. 19 is supplied.

  When the two-screen display mode is selected, the two-screen insertion circuit unit 19 performs a process for displaying a viewing video on the right screen and a video adjustment image on the left screen. The matrix circuit unit 20 adds the display characteristic data set by the display characteristic setting circuit unit 21 to the video data from the screen insertion circuit unit 19 and converts it into RGB data. The synthesized video generation unit 22 synthesizes the RGB data from the matrix circuit unit 20 and the on-screen image data from the on-screen display image generation unit 23 to generate one screen image data. The on-screen display image generation unit 23 supplies on-screen image data of the above-described start screen and video adjustment screen to the composite video generation unit 22 based on a command signal from the control unit 10. The video data synthesized by the synthesized video generation unit 22 is converted into an analog signal by the D / A conversion unit 24 and output to the display unit.

  When the two-screen display mode is selected, the control unit 10 issues a command signal to the two-screen insertion circuit unit 19, and the two-screen insertion circuit unit 19 divides the screen into two according to the command, and the left screen is used for video adjustment. The compressed viewing video is displayed on the screen and the right screen. Further, when the user selects a setting item to be confirmed or adjusted, the control unit 10 issues a command signal to the video adjustment screen generation unit 18 based on the information, and the video adjustment screen generation unit 18 corresponds to the setting item. The image data for function explanation is supplied to the two-screen insertion circuit unit 19. In addition, when the user performs a setting operation for changing a setting value or changing a setting state, the control unit 10 issues a command signal to the display characteristic setting circuit unit 21 based on the information, and the display characteristic setting circuit unit 21 is nonvolatile. The setting information stored in the memory is rewritten with the changed setting value or setting state.

  Next, in the television receiver of FIG. 1 to which the present invention is applied, an operation when performing video adjustment will be described using a screen display example. Note that the following operations are performed using a remote controller, and the remote controller is provided with a menu key, a numeric keypad, an increase / decrease (+-) key, an enter key, a cross key, a return key, and the like.

  When the menu key for adjusting the image is pressed while the viewing image is displayed on the screen, the image adjustment start screen shown in FIG. 2 is displayed first, and “YES” is selected when the two-screen display mode is selected. Is switched to the two-screen display shown in FIG. 3, the viewing video that has been viewed up to now is displayed on the right screen, the setting menu screen for video adjustment and the default or previous items used on the left screen The function explanation image is displayed. As described above, image data for still images and moving images is prepared as function explanation images, and images suitable for the respective items are displayed. The display example in FIG. 3 shows an image for explaining the function of “quick shoot”, which is a function that makes a fast-moving image clear and clear, and makes it easier to see on a liquid crystal television. A pair of videos with and without are displayed side by side. In this case, using a moving image is extremely effective for understanding the function.

  When changing the setting value, operating the increase / decrease key changes the display level of the numeric bar of the highlighted item name, and the change is reflected in one of the displayed function explanation images, for example, the left image Thus, it is possible to confirm how the afterimage feeling of fast moving images is reduced. When the user makes adjustments while watching the change in the image and presses the enter key when the desired display characteristics are obtained, the changed display characteristics are reflected in the viewing video on the right side of the screen. In addition, the setting value of the quick shoot stored in the nonvolatile memory in the display characteristic setting circuit unit 21 is rewritten to the setting value after the change.

  Subsequently, when selecting the next item “3D Y / C separation”, the up / down direction key is operated to highlight the item. In the case of this item, an OFF pattern image in which rainbow color noise is generated and an ON pattern image in which rainbow color noise is reduced are displayed, and the function can be understood. It is like that. In this case, a still image is more suitable than a moving image. FIG. 5 shows a display example in the case of “black stretching”, which is a function of tightening black and eliminating a black float to give a sense of depth, and a still image is also suitable in this case.

  FIG. 6 shows a screen display example of the single screen display mode when the two-screen display mode is not selected on the selection screen of FIG. 2. In this case, the entire screen becomes a video adjustment screen. Cannot be displayed. Instead, since the function explanation image can be displayed in a large size, there is an advantage that it is easy to confirm the item for which it is necessary to confirm the details of the image. In the example shown in the figure, the item “quick shoot” described above is used. However, in the case of a moving image, a large screen is often easier to understand.

FIG. 7 shows a flowchart of the video adjustment process in the present invention.
First, when viewing video is displayed on the screen, when the menu key is pressed to select the “video adjustment” item, the video adjustment start screen of FIG. 2 is displayed on-screen (S1), and the display mode is selected. (Step S2) When the two-screen display is selected (Step S3 / Y), the screen is switched to the two-screen display of FIG. 3 described above, and the image adjustment screen is displayed on the left screen (Step S4). FIG. 3 shows a display example in which an image for explaining the function of the item positioned first in the menu item is displayed by default as an example.

When another item is highlighted by operating the up / down key from the currently highlighted item (step S5), the function explanation image displayed so far is switched to the highlighted item (step S6). ). Subsequently, when the up / down direction key is operated, the process returns to step S5 (step S7), and the screen is switched to the function explanation screen selected by the operation.
When the increase / decrease key (or left / right direction key) is operated in step S7, the setting condition of the selected item is changed, and the changed display characteristics are reflected in one of the pair of function explanation images (step S8). In the two-screen display mode, the display characteristics being adjusted may be reflected in the viewing video displayed on the right screen.
In this way, by operating the up and down direction keys on the display screen of FIG. 3, the function explanation images of the respective items can be sequentially displayed, and the change of the display image can be confirmed by operating the increase / decrease keys. During step S9, the function confirmation mode can be used by operating the up / down direction key and the increase / decrease key (or the left / right direction key).

When the setting key is changed by operating the increase / decrease key (or the right / left direction key) and the image of the desired display characteristics is obtained while viewing the function explanation image that changes accordingly, the determination key is pressed (step S9). The setting change is also reflected in the viewing video displayed on the right screen, and the setting value or state stored in the nonvolatile memory is rewritten to the setting after the change (step S10).
When changing the setting of another item or confirming the function, the process returns from step S11 to step S5 by operating the up / down direction key, and the same processing is repeated until step S10.

Also, when setting change or function confirmation is performed in the single screen display mode, if the return key is pressed in step 11, the process returns to step 1, and if "NO" is selected on the display screen of FIG. 2, the process proceeds to step 12, and FIG. Is displayed on one screen (step S12). Subsequent steps S13 to S19 are basically the same as steps S5 to S11 described above, and a description thereof will be omitted.
To end the video adjustment mode, when the menu key is pressed between steps 7-11 or 15-19, the screen returns from the video adjustment screen to the normal screen (step S20), and the video adjustment mode ends.

  In addition, when the image data of the function explanation image in the present invention is stored in the memory, since the moving image data requires a larger capacity than the pattern image or the still image, the moving image data of the short time video is used. The video may be replayed repeatedly until the function check or setting value adjustment of the item is completed.
