Description

  Embodiments described herein relate generally to image adjustment of an image display device.

  A conventional image display device, such as a monitor device, displays a setting menu for displaying image adjustment items and the degree of adjustment (adjustment value) on the screen by OSD (On Screen Display), and operates buttons provided on the main body. By doing so, adjustment items and adjustment values are set.

  In recent years, since images with various aspect ratios have been handled, the screen of the monitor device can be rotated 90 degrees. Since the display position of the setting menu by OSD is determined with respect to the image, when the screen is rotated 90 degrees, the setting menu is also rotated together with the image. For this reason, the menu characters are rotated by 90 degrees and the display position is changed, which makes the menu difficult to use. When the screen is rotated 90 degrees, the up / down / left / right direction of the main body button is shifted from the up / down / left / right direction on the menu in the image.

Japanese Patent Laid-Open No. 2001-256768

  When the conventional electronic device rotates the screen, the setting menu for image adjustment also rotates with the image, and there is a problem that the operability of the menu is lowered.

  An object of the present invention is to provide an electronic device, a method, and a program for displaying various menus on a screen so that the operability of the menu does not deteriorate even when the screen is rotated.

  According to the embodiment, the electronic device includes an image adjustment unit, a menu display unit, an operation button, and a rotation processing unit. The image adjusting unit adjusts an image displayed on the image display unit.

As shown in FIG. 1A, the system includes a monitor device 10 including an LCD panel and a video source device 14. The video source device 14 is a device that supplies a video signal to the monitor device 10, and includes a TV tuner, a DVD (registered trademark) / BD (registered trademark) player, a set top box, and the like. The video source device 14 and the monitor device 10 are connected by a cable 16 according to a video display standard such as HDMI (registered trademark) or a display port. The HDMI standard includes, for example, HDMI 2.0 and HDMI 1.4. Note that the monitor device 10 and the video source device 14 are not necessarily physically separated, and the embodiment may be a television receiver in which both are integrated. The content displayed on the monitor device 10 is not limited to a moving image, but may be a still image (photo). In this case, the video source device 14 may be a memory card that stores photos, a USB memory, or the like.

  As shown in FIG. 1B, a power button 20 and an operation button 18 are provided below the right end of the back surface of the monitor device 10. These buttons can be operated by a user located on the front side by extending the index finger, middle finger, ring finger, etc. of the right hand to the back. The operation button 18 is composed of double concentric buttons, the center button 18a is a decision button, and the outer circular button 18b is a button that can be operated in four directions, up, down, left, and right. The outer button 18b only needs to be operable in four directions, and is not limited to an annular shape. The outer button 18b may be a cross shape, or may be four buttons, upper, lower, left, and right. In the case of an annular shape, a vertically long elliptical ring shape may be used so that the top / bottom and the left / right can be easily recognized by a fingertip. The determination button 18a is used to display an adjustment item and an adjustment value setting menu 12 when the monitor device 10 adjusts an image.

  As will be described later, the setting menu 12 includes, for example, various horizontal writing items arranged in the vertical direction, and the items can be selected by the up / down operation of the up / down / left / right button 18b. The adjustment value or choice of the selected item can be set by the left / right operation of the up / down / left / right button 18b.

  If there is an installation space in the front frame of the monitor device 10, the power button 20 and the operation button 18 may be provided on the front instead of the back.

  FIG. 2 is a block diagram showing a system configuration of the monitor device 10. A video input unit (for example, HDMI input unit) 22 to which a video signal is input from the video source device 14 is connected to the video processing unit 24. The video processing unit 24 adjusts the video signal with respect to various items (for example, backlight, color temperature, contrast, black level, gamma characteristic, hue, color density, sharpness, etc.). The set value is given from the system controller 28. The system controller 28 includes a CPU. The output of the video processing unit 24 is displayed on the LCD panel 26. The system controller 28 is connected to a flash memory 30 that stores setting values of adjustment items, an operation unit 32, an OSD signal generation unit 38, a backlight 40, and the like.

  The system controller 28 sets the setting value read from the flash memory 30 in the video processing unit 24. The flash memory 30 also stores software (firmware) for controlling the operation of the CPU included in the system controller 28. The operation unit 32 includes an operation button 18 and a power button 20 provided on the back surface of the monitor device 10 described above. The OSD signal generator 38 creates a video adjustment menu displayed on the LCD panel 26 by OSD. The output of the OSD signal generation unit 38 is supplied to the video processing unit 24, and a video adjustment menu is superimposed on the video. The system controller 28 also controls the brightness and color temperature of the backlight 40.

Next, image adjustment according to the embodiment will be described.
When the determination button 18a among the operation buttons of the monitor device 10 is pressed, a video adjustment menu as shown in FIGS. 3A and 3B is displayed superimposed on the video by the OSD. When the enter button 18a is pressed again in this state, the menu display is turned off.

  The video adjustment menu is a three-level menu, and the first-level menu displayed initially includes three items of input settings, video settings, and main device settings, and their icons. Three horizontal writing items are displayed side by side in the vertical direction (vertical direction).

  The display position of the video adjustment menu is set to the lower left of the screen, but can be changed by the user's setting. The menu may be displayed by completely replacing the video at the same position (with the video hidden), but the video and the menu may be superimposed at a certain ratio so that the video can be seen under the menu.

When the cursor is moved by the operation of the up / down button and an item is selected, a second hierarchy menu including the sub-item of the item and the adjustment value is displayed on the right side of the first hierarchy menu. 3A and 3B show a case where the video setting is selected in the first hierarchy menu. That is, a second hierarchy menu including backlight, color temperature, RGB Drive, and LED area control, which are sub-items for video settings, is displayed side by side in the first hierarchy menu. The setting values of each item are 40 cd / m ^{2 for the} backlight, 15,000 K for the color temperature, R: 50, G: 50, B: 50 for RGB Drive, and LED area control is OFF.

When a sub item, for example, a backlight is selected by operating the up / down button, a slider for adjusting the setting value of the sub item is displayed, and the value is adjusted by operating the left / right button. The backlight is set in increments of 40 cd / m ² to 350 cd / m ² . The color temperature is set in increments of 100K in the range of 4,000K to 15,000K. RGB Drive is set in the range of 0 to 100% for each of R, G, and B. Note that RGB Drive cannot be set so that the total of R, G, and B is 30 or less. Also, the color temperature and RGB Drive are exclusive.

  Thus, the item is selected by pressing the up / down key to move the cursor. When the cursor reaches the uppermost item and the upper key is pressed, the cursor moves to the lowermost item. Similarly, when the cursor reaches the bottom item and the down key is pressed, the cursor moves to the top item. Thus, the up and down keys move the cursor in a loop.

  Selection of item choices (setting values) is performed by pressing the left and right keys. The left and right keys may be moved in a loop as in the case of the up and down keys. However, in the case of a set value, it may be preferable not to move the cursor. It is optional to move or not move in a loop.

  3A shows a menu display when the monitor device 10 is installed horizontally, and FIG. 3B shows a menu display when the monitor device 10 is rotated 90 degrees clockwise from the state of FIG. 3A and installed vertically. The video processing unit 24 normally processes a horizontally long image so as to be suitable for a horizontally long monitor device and supplies the processed image to the LCD panel 28. As shown in FIG. 3B, when the installation direction of the monitor device 10 is rotated vertically, the image processing unit 24 rotates the image so that the horizontally long image fits the vertically long monitor device 10 and applies it to the LCD panel 28. Supply. There are several processes for rotating the image. For example, there are a method of displaying a horizontally long image on a vertically long screen with a reduced resolution (black bands remain at the top and bottom), and a method of cutting the left and right end portions and displaying the center vertically long portion without changing the resolution. . FIG. 3B is an example of the latter. Even if the installation direction of the monitor device 10 is rotated vertically, the video processing unit 24 performs processing so that the menu is displayed at the same position as before rotation, that is, at the lower left of the screen but without being rotated. For this reason, even if the screen is rotated, the menu is always displayed in horizontal writing at the same position on the screen independently of the rotation of the image.

  Although the rotation of the monitor device 10 can be detected by an acceleration sensor or a structural contact switch, in this embodiment, when the user rotates the screen, some rotation position signal is input from the operation unit 32. .

  3A and 3B show an example in which the lower hierarchy menu is displayed side by side on the right side of the upper hierarchy menu. However, when the lower hierarchy menu is displayed, the display of the upper hierarchy menu is turned off and the upper hierarchy menu is displayed. Instead of, a lower hierarchy menu may be displayed. The display mode of the menu can be variously modified depending on circumstances such as the display space.

  In the example of FIGS. 3A and 3B, the aspect ratio of the menu display area is not changed before and after the rotation. However, when the lower-level menu is sequentially displayed on the right side of the upper-level menu, the aspect ratio of the vertically long screen is If the width of the menu is wide and difficult to see, the menu display area can be changed to a vertically long shape by changing the aspect ratio of the menu display area as shown in FIGS. 4A and 4B as the screen rotates. It is. Alternatively, the slider width may be shortened simply by reducing the magnification of the slider. Since the layout changes when the aspect ratio of the menu is changed, the menu display area is reduced by changing the character size or resolution without changing the aspect ratio, as shown in FIGS. 4A and 4C. It may correspond to portrait.

When the input setting is selected in the first hierarchy menu, a second hierarchy menu including the following sub-items is displayed as shown in FIGS. 5A and 5B.
The sub items of the input setting are input, video signal, audio signal, video mode, installation direction, and IP address. The sub item options are as follows.
The input options are HDMI-1 / HDMI-2 or HDMI-Dual / Displayport (SST / MST). Video signal options are no signal, no support, RGB / YPbPr (4: 4: 4/4: 2: 2/4: 2: 0) **** Hx **** (** Hz), interlaced / Progressive. The audio signal options are no signal, no support, HDMI-x, and L-PCM 2ch (** KHz). Video mode options are user, Adobe RGB, sRGB, BT. 709, EBU / SMPTE-C / DCI / DICOM-sim, (memory / calibration / calibration (memory). The installation direction options are landscape (landscape) and portrait (portrait). The choices are disconnected and address values, which are sequentially selected by the operation of the left and right buttons, and are determined by the operation of the decision button 19a, whereby the monitor device 10 recognizes the installation direction. The video processing unit 24 can perform image rotation processing.

  5A and 5B show HDMI-1 as input, RGB (4: 4: 4), 3840Hx2160V (24 Hz) as video signal, progressive, L-PCM 2ch (48 KHz) as audio signal, and Adobe as video mode. RGB shows an example in which landscape (landscape) is set as the installation direction and 192.168.0.3 is set as the IP address.

  Although not shown, when main unit setting is selected from the first layer menu, video input, video mode, adjustment mode, color temperature, backlight, headphone volume, software (firmware) update, initialization, input in progress A menu including items such as format display of the video signal, display of the IP address of the apparatus, display of the elapsed time since the calibration was performed, and software version display is displayed.

Options for each item are as follows, for example. Video input is set to one of HDMI1 / HDMI2 / display port. The video mode is Adobe RGB / sRGB / BT. 709 / EBU / SMPTE-C / DICOM-sim / TV / movie. The adjustment mode is set to either preset / custom. The color temperature is set in increments of 100K in the range of 4000K to 15000K. The backlight is set in increments of 40 cd / m ² to 350 cd / m ² (manual setting only). The volume of the headphones is set in increments of 5 in the range of 0 to 100 (can be set when the headphones terminal is inserted). Software (firmware) update and initialization are set to either “execute” or “do not execute”. The video signal format, IP address, elapsed time after calibration, and software version are automatically displayed. Note that the calibration is color calibration, in which a sensor connected to the USB terminal of the monitor device 10 is brought into close contact with the LCD panel 26 to measure luminance and color, and is automatically adjusted.

  FIG. 6 is a view of the monitor device 10 as viewed from the front. In the case of landscape, as shown in FIG. 6A, a menu 54 is displayed at the lower left, and an operation button is located at the lower right (viewed from the front) of the back. The four areas 52a, 52b, 52c, and 52d of the operation buttons correspond to the upper button, the right button, the lower button, and the left button, respectively. The functions of the up button 52a, the right button 52b, the down button 52c, and the left button 52d are as follows: “Select the item one up”, “Select the value increase or next (one right) option”, “One down” “Select an item” and “Select a value decrease or previous (one left) option”.

When the screen is rotated 90 degrees clockwise by 90 degrees and becomes vertically long, as shown in FIG. 6B, the position of the operation button changes to the lower left of the back (viewed from the front). At this time, if the definition of each area of the button (corresponding to the up / down / left / right button) is the same as in FIG. The operation feels bad. Therefore, in this embodiment, since the operation button is rotated 90 degrees, the definition of the four areas 52a, 52b, 52c, and 52d is also rotated 90 degrees. That is, the areas 52a, 52b, 52c, and 52d change to a right button, a down button, a left button, and an up button, respectively. Table 1 shows changes in the definition of the four areas on the top, bottom, left, and right of the operation button depending on the screen orientation. This allows the button areas located on the top, right, bottom, and left (viewed from the front of the screen) to function as the top button, right button, bottom button, and left button, respectively. Can be correctly selected.

FIG. 7 is a flowchart illustrating a flow of image adjustment processing according to the embodiment.
When the operation of the enter button 18a is detected in block B62, a menu is displayed in block B64. When the operation of the up / down / left / right button is detected in block B66, it is determined in block B68 whether the setting direction of the screen is vertically long. If it is vertically long, the rotation processing of the video processing unit 24 is turned on in block B70 (the display of FIGS. 3B and 4B is realized), and the definition of the up / down / left / right buttons is changed according to Table 1 in block B72. Thereafter, in block B74, an item is selected or an adjustment value is set according to a key signal from the up / down / left / right button. If the block B68 is determined to be horizontally long, the blocks B70 and B72 are skipped.

  When the operation of the enter button 18a is detected in block B76, the menu display is turned off in block B78, and the process ends. When the operation of the enter button 18a is not detected in block B76, the process returns to block B64 and the menu display is continued.

  According to the present embodiment, when the screen is rotated 90 degrees in an electronic device that displays a menu for setting image adjustment items superimposed on the image, the image is rotated 90 degrees, but the menu is not rotated. Display in the same position as before rotation. And the function at the time of operation of each direction of the button which can operate four directions of up and down, right and left provided in an apparatus is changed according to rotation. As a result, even if the screen is rotated, the correspondence between the upper, lower, left, and right of the menu and the left, right, and upper of the button does not change.
