Description

  The present invention relates to a display device, and more particularly to adjustment of display parameters thereof.

  A technique has been proposed in which a linear sensor is provided on a display device, and display parameters are adjusted according to the position of a user's finger on the sensor. For example, Patent Document 1 discloses a technique as shown in FIG.

  As shown in FIG. 1A, the display 2 is provided with a slide pad 4. When the user touches the slide pad 4, a menu for parameter adjustment is displayed on the screen of the display 2. When a desired parameter is selected from the menu, a scroll bar 6 for adjusting the horizontal position is displayed, for example, as shown in FIG. 1B. When the user touches the slide pad 4, the horizontal position is adjusted according to the position.

  In Patent Document 1, the parameters are changed so as to correspond to the finger detection position of the slide pad 4. In Patent Document 2, the parameter change rate is changed in accordance with the detection position of the slide pad 4. For example, still playback is performed at the center of the slide pad 4, fast-forwarding is performed on the right side, and rewinding is performed on the left-hand side.

JP 2006-301736 A

  In any of the above prior arts, accurate parameter adjustment is difficult unless the user is aware of where the finger is touching on the slide pad. In the technique of Patent Document 1, since the parameter is directly determined according to the finger position, it is important to recognize the finger position. Further, in the technique of Patent Document 2, since the change rate of the parameter changes according to the distance of the finger from the midpoint, it is important to recognize where the midpoint is.

  However, the conventional technique has a problem in that the operation is complicated because the slide pad must be watched at the time of parameter adjustment. Further, in the technique such as Patent Document 2, in addition to the above-described problem, a physical mark for indicating the midpoint must be provided. There was also a problem that the display was confused. These problems are applicable not only to display devices but also to other devices that require parameter adjustment in general.

BEST MODE FOR CARRYING OUT THE INVENTION

1. First embodiment
1.1 Overall Configuration FIG. 2 is a functional block diagram of a display device according to an embodiment of the present invention. The position detection sensor 10 detects the position of the user's finger that is the detection target. The first position detection means 12 receives the output from the position detection sensor 10 and sets the position where the finger is detected as the first position.

  The control value determination means 14 receives the output from the position detection sensor 10 and determines the position where the finger is detected after the first position is determined as the second position. Further, the control value determining means 14 determines a control value based on the relative positional relationship between the first position and the second position.

  The adjusting unit 16 receives the control value from the control value determining unit 14 and adjusts the display parameter on the display unit 18.

  Therefore, the user can adjust the display parameters by moving the finger around the position on the position detection sensor 10 where the finger is placed for a predetermined time or more.

1.2 Hardware Configuration FIG. 3 shows the hardware configuration of the display device shown in FIG. The tuner unit 20 receives a high frequency signal from the antenna terminal and restores a video signal and an audio signal. The video signal is supplied to the video signal processing unit 22, and the audio signal is supplied to the audio signal processing unit 24.

  The video signal processing unit 22 is also given a video signal as an external input. The video signal processing unit 22 switches between the video signal from the tuner unit 20 and the externally input video signal in accordance with the video control signal from the MPU unit 26.

  The on-screen display (OSD) signal generation unit 30 generates an image for control or the like as an OSD signal in accordance with a control signal from the MPU unit 26. The OSD signal adding unit 28 superimposes the OSD signal on the video signal from the video signal processing unit 22. The video signal on which the OSD signal is superimposed is displayed on the display unit 18. The display unit 18 is provided with a backlight unit 38, and the brightness of the backlight is adjusted under the control of the MPU unit 26.

  An audio signal from the outside and an audio signal from the tuner unit 20 are given to the audio signal processing unit 24. The audio signal processing unit 24 switches between the audio signal from the tuner unit 20 and the externally input audio signal in accordance with the audio control signal from the MPU unit 26. The audio signal from the audio signal processing unit 24 is output as sound from the speaker 36.

  The MPU unit 26 includes a CPU, a memory, and the like, and controls the tuner unit 20, the video signal processing unit 22, the audio signal processing unit 24, the backlight unit 38, and the like. In addition, control signals for external devices can be output by CEC, i-LINK, infrared rays, and the like. A control program for adjusting various parameters is recorded in the memory of the MPU unit 26.

  The MPU unit 26 receives an operation signal from an operation button (not shown), the remote controller 34, or the like, and performs control corresponding thereto. The MPU unit 26 receives a position detection signal from the slide bar 32 that is a position detection sensor. In this embodiment, the slide bar 32 is provided in the lower part of the display part 18, as shown in FIG.

  The slide bar 32 includes a plurality of n touch sensors arranged, and position detection can be performed depending on which sensor has output. As a sensor for the slide bar 32, a sensor that detects pressure, a sensor that detects capacitance, a sensor that detects light, and the like can be used. In addition, a sensor that continuously detects the position (for example, a sensor whose capacitance changes depending on the position) may be used instead of the n sensors.

1.3 Parameter Adjustment Processing FIGS. 5 and 6 are flowcharts of control programs recorded in the MPU unit 26. FIG. The MPU unit 26 determines whether or not the slide bar 32 has been tapped by the user (step S1). Here, tapping means that there is a detection output from the slide bar 32 for a time shorter than a predetermined time. That is, the user touches the slide bar 32 and immediately releases it.

  When detecting the tapping, the MPU unit 26 controls the OSD signal generation unit 30 to display a menu for parameter adjustment on the display unit 18 (step S2). An example of the menu displayed on the display unit 18 is shown in FIG.

  In FIG. 7, menus M1 to M7 are displayed as pictures. Menu M1 indicates picture adjustment, menu M2 indicates color adjustment, menu M3 indicates power saving control, menu M4 indicates other adjustments, menu M5 indicates information display, menu M6 indicates language setting, and menu M7 indicates menu end. In the figure, the cursor C is positioned on the menu M2.

  When the user touches the slide bar 32, the MPU unit 26 moves the cursor C according to the detected position (step S3). Therefore, the user can perform menu selection by touching the slide bar 32. In this embodiment, the slide bar 32 is associated with menus M1, M2, M3, M4, M5, M6, and M7 from the left side to the right side.

  Next, the MPU unit 26 detects whether or not the slide bar 32 has been tapped again (step S4). When this is detected, the MPU unit 26 displays a detailed menu corresponding to the menu where the cursor C is located when tapped (step S5).

  FIG. 8 shows a detailed menu of the color adjustment menu M2. Menu M21 indicates brightness, menu M22 indicates color temperature, menu M23 indicates gamma adjustment, menu M24 indicates color intensity, menu M25 indicates hue, menu M26 indicates reset, and menu M27 indicates return. When the user selects a menu with the slide bar 32 and performs tapping (steps S6 and S7), processing corresponding to the detailed menu is executed (step S8).

  Here, the description is made assuming that the detailed menu M21 of brightness shown in FIG. 8 is selected. When the brightness detail menu M21 is selected, the MPU unit 26 controls the OSD signal generation unit 30 to display an adjustment bar for brightness adjustment on the display unit 18 (step S11 in FIG. 6).

  FIG. 9 shows a display example of the adjustment bar 40. On the upper part of the adjustment bar 40, numbers “0”, “50” and “100” indicating the brightness value are displayed. The current brightness is indicated by bar 42.

  The user can adjust the parameter (here, brightness) by touching the slide bar 32. In this embodiment, the jog mode and the shuttle mode can be adjusted by touching the slide bar 32.

  In the jog mode, according to the difference between the position (first position) of the slide bar 32 first touched by the finger and the position of the finger (second position) moved without being separated from the slide bar 32, The amount of parameter change can be changed continuously. When the finger is removed from the slide bar 32, the parameter change is stopped.

  In the shuttle mode, the parameter changing speed can be continuously changed according to the difference between the first position and the second position.

  First, the jog mode will be described. When the adjustment bar 40 is displayed in step S11, the MPU unit 26 determines whether there is a detection output from the slide bar 32 (steps S12 and S13).

  If there is a detection output, it is determined in step S14 whether or not the detection position is different from the previous time. Here, since the detection is made for the first time after displaying the adjustment bar 40, the detection position is not the same as the previous time, and the process proceeds to step S15.

  In steps S15 and S16, adjustment is performed by detecting a difference based on the previous detection position. However, since there is no previous detection position, nothing is performed and the process proceeds to step S17.

  In step S17, the current detection position is recorded in the memory of the MPU unit 26 as the previous detection position. In this way, the first position is recorded in the memory.

  In order to operate as the jog mode, the user moves his / her finger on the slide bar 32 without touching the same position on the slide bar 32 for a long time.

  Subsequently, the MPU unit 26 determines whether or not there is a detection from the slide bar 32 (steps S12 and S13). When there is position detection, the MPU unit 26 determines whether or not the current detection position is different from the previous detection position recorded in the memory (step S14). If they are different, the process proceeds to step S15.

  In step S15, the MPU unit 26 calculates the difference between the current detection position (second position) and the previous detection position (first position). Based on the calculated difference, the MPU unit 26 calculates a parameter (brightness here) change amount as a control value. Then, a video control signal (control value) is output to the video signal processing unit 22 and adjusted so that the brightness changes by the calculated change amount (step S20).

  Note that the greater the difference is, the greater the brightness change amount is controlled. In this embodiment, the parameter change amount V is calculated as a magnitude proportional to the difference.

  If the second position is on the right side of the first position, the parameter is changed to the “positive” direction. If the second position is on the left side, the parameter is changed to the “negative” direction. In other embodiments, conversely, the change may be “negative” on the right side and “positive” on the left side.

  Next, the MPU unit 26 displays the changed brightness value (parameter value) on the adjustment bar 40 (step S16).

  Thereafter, the MPU unit 26 records the current position as the previous position (first position), and executes step S12 and subsequent steps (step S17). Therefore, next, the same adjustment can be performed using the place where the slide bar 32 is touched as the second place.

  As shown in FIG. 10A, it is assumed that the relationship between the first position P1 and the second position P2 touched by the user in the slide bar 32 is determined. In this case, the display of the adjustment bar 40 indicating the brightness changes from “before change” to “after change” in FIG. 10A.

  As shown in FIG. 10B, if the first position P1 and the second position P2 are close to each other, the amount of change in brightness is also small.

  As shown in FIG. 10C, if the second position P2 is to the left of the first position P1, the brightness change amount is “negative”.

  Therefore, the user does not need to visually confirm the center point of the slide bar 32 and can adjust the point touched by himself / herself as the center point.

  In this embodiment, in addition to the jog mode described above, a shuttle mode is also provided. When the user wants to make an adjustment in the shuttle mode, the user keeps touching the same position of the slide bar 32 (so-called “long press”). The MPU unit 26 receives and determines the position detection output from the slide bar 32 at a predetermined interval (for example, every 0.5 seconds). In step S14, if the detected position is the same as the previous time, the process proceeds to step S18. In step S18, it is determined whether the same position has been reached a predetermined number of times (for example, 4 times). If it is detected that the position is the same for a predetermined number of times, the MPU unit 26 shifts to the shuttle mode, assuming that “long press” has been made.

  In the shuttle mode, the MPU unit 26 records, in the memory, the detection position “long pressed” as the first position (step S19). Subsequently, as shown in FIG. 11, the MPU unit 26 displays the shuttle mode adjustment bar 44 in addition to the adjustment bar 40 (step S20). As shown in FIG. 11, the shuttle mode adjustment bar 44 preferably has the same length as the slide bar 32 and is displayed in parallel so that the positional relationship thereof corresponds.

  The full length of the shuttle mode adjustment bar 44 corresponds to each detection position of the slide bar 32. As shown in FIG. 11, the MPU unit 26 displays the first position P <b> 1 detected as “long press” on the shuttle mode adjustment bar 44. Further, with the first position P1 as the center, a "positive" parameter change amount (2, 4, 8, 16) is displayed on the right side, and a "negative" parameter change amount (-2) is displayed on the left side. Since the change amount in the shuttle mode is a change amount per predetermined time, it can be called a parameter change speed.

  Next, the MPU unit 26 determines whether or not the user keeps touching the slide bar 32 with a finger (whether the position detection output of the slide bar 32 continues after the first position determination) (steps S21 and S22). . If the finger is released, the MPU unit 26 releases the shuttle mode and returns to step S11.

  If the finger is not released (if the position detection output of the slide bar 32 continues), the current finger position is acquired as the second position by the detection output of the slide bar 32. If the user moves the finger without releasing it from the slide bar 32 after performing “long press”, the second position is different from the first position.

  The MPU unit 26 determines a parameter (brightness) change speed (amount of change per predetermined time) as a control value based on the difference between the first position and the second position. Then, a video control signal (control value) is output to the video signal processing unit 22, and adjustment is performed so that the brightness changes at the determined change speed (step S23).

  At this time, the MPU unit 26 displays the current detection position on the shuttle mode adjustment bar 44 as the second position P2, as shown in FIG. Thus, the user can know the parameter change speed.

  Subsequently, the MPU unit 26 displays the changed brightness value (parameter value) on the adjustment bar 40 (step S24).

  The MPU unit 26 returns to Steps S21 and S22, determines whether or not there is a detection output of the slide bar 32, and repeats the above processing if there is a detection output. Therefore, unlike the jog mode, the brightness is continuously changed at the change speed corresponding to the difference between the first position and the second position without repeating the movement of the finger (slide operation) on the slide bar 32. Will change. See the changes in (1), (2), and (3) in FIG. 12A.

  Further, the change speed can be changed by moving the position of the finger on the slide bar 32. In this embodiment, the difference between the first position and the second position and the change speed are not changed linearly, and if the difference between the first position and the second position becomes large, the change speed is further increased. (For example, exponentially increases) (see the shuttle mode adjustment bar 44 in FIG. 11). Therefore, it can be quickly changed with relatively coarse accuracy until it approaches the target parameter value, and the amount of change can be adjusted with fine accuracy when it approaches the target value, and the operation is easy.

  As in the jog mode, when the first position and the second position are reversed, the parameter changing direction is reversed. See the changes in (4), (5) and (6) in FIG. 12B.

  In this embodiment, the jog mode and the shuttle mode are switched depending on whether or not the slide bar 32 is “long pressed” in order to determine the first position. Therefore, mode switching can be performed in the parameter change processing operation, and a complicated mode switching operation is unnecessary.

  Further, in this embodiment, the MPU unit 26 can perform the same control as described above by giving a control signal by CEC, i-LINK, infrared, or the like to an externally connected device such as a display.

  In the above description, brightness has been described as an example for control purposes, but other adjustments such as time adjustment, horizontal / vertical position, black level, contrast, color density, hue, color temperature, contour correction, RGB gain, gamma correction, screen size, etc. You may make it adjust for a display parameter as a control objective.

  Furthermore, adjustments may be made for the purpose of control, such as sound parameters such as volume, sound quality, and balance other than display parameters. Further, channel and program selection and frequency tuning in the tuner unit may be used for control purposes.

  The adjustment according to this embodiment is particularly effective for continuously changing parameters.

1.4 Other Embodiments In the above embodiment, only the adjustment bar 40 is displayed in the jog mode. However, as shown in FIG. 13, the jog mode adjustment bar 46 may be displayed in addition to the adjustment bar 40, as in the shuttle mode. The jog mode adjustment bar 46 shows a first position P1 and a second position P2.

  In the above embodiment, the parameter change amount is determined in association with the difference between the first position and the second position. However, the parameter change rate may be associated with the difference. That is, a change rate of how much the current parameter value is changed according to the difference may be determined, and thereby the change amount may be calculated. This can be applied to both the shuttle mode and the jog mode. When applied to the shuttle mode, the change amount (per predetermined time) may be calculated by multiplying the change rate based on the parameter value when the first position is always determined. The change amount (per predetermined time) may be calculated by multiplying the change rate based on the later parameter value.

  In the above embodiment, the parameter change amount (change rate) is calculated based on the difference between the first position and the second position. In this case, various relational expressions such as a quadratic function and an inverse proportion can be used as well as a simple proportion.

  In the above embodiment, in the shuttle mode, the parameter change speed is confirmed by the shuttle mode adjustment bar 44. However, in addition to or instead of the shuttle mode adjustment bar 44, as shown in FIG. 14, the change speed may be indicated near the tip 42a of the bar 42 indicating the parameter amount. In the example of FIG. 14, the change speed is “10”, and it can be known that the direction of the arrow is rightward, so that it is a change in the increasing direction (if the arrow is in the opposite direction, the direction is decreasing). . This display moves in the same manner as the tip 42a of the bar 42 moves with the change of the parameter. At the time of parameter adjustment, since the tip 42a of the bar 42 is watched, it is possible to easily know the current parameter change speed.

  In the above-described embodiment, it is detected that the slide bar 32 is “long pressed” and the shuttle mode is entered. However, switching to the shuttle mode or the jog mode may be performed not only for “long press” but also for a specific position detection mode such as “tapping”.

  In the above embodiment, in the jog mode, the detection value when the finger is moved from the first position without being separated from the slide bar 32 is set as the second position. However, the place where the finger is removed from the first position and touched again may be set as the second position. Further, in the shuttle mode, a position where the position detection is performed again after the first position is determined may be used as the second position.

  In the embodiment described above, whether the jog mode or the shuttle mode is selected may be displayed on the display unit 18. For example, the color of the adjustment bar 40 or the bar 42 may be changed between the jog mode and the shuttle mode. Further, the color of the bar 42 may be changed depending on whether the parameter is increased or decreased.

  In the above embodiment, if the first position is not the center of the slide bar in the shuttle mode, the change speed (absolute value) is different between the right end and the left end of the slide bar 32 (shuttle mode in FIG. 11). Adjustment bar 44). However, the change speeds (absolute values) at the right end and the left end of the slide bar 32 may be made equal regardless of where the first position is. In this case, the shuttle mode adjustment bar 44 may be as shown in FIG. Such a method can be applied not only to the shuttle mode but also to the jog mode.

  Further, as shown in FIG. 16, the change speed may be set by folding the slide bar 32. For example, assume that the first position P1 is determined in the slide bar 32 as shown in FIG. 16A and the finger is moved in the left direction. At this time, the MPU unit 26 displays the shuttle mode adjustment bar 44 as shown in FIG. 16A.

  When the user further moves his / her finger to the left and reaches the left end of the slide bar 32 as shown in FIG. 16B, the MPU unit 26 changes the display of the shuttle mode adjustment bar 44 as shown in FIG. 16B. That is, the user can obtain a larger change speed by moving the finger in the opposite direction from here. For example, when the finger is moved to the second position P2 in FIG. 16C, a change speed greater than “−4” can be obtained.

  When the finger is positioned at the left end of the slide bar 32 again, the MPU unit 26 returns to the display as shown in FIG. 16D.

Such a method can be applied not only to the shuttle mode but also to the jog mode.
In the above embodiment, a menu is displayed when the slide bar 32 is tapped. However, menu selection may be performed by a button provided separately from the slide bar 32. Alternatively, the menu display may be performed only by detecting the position instead of tapping. Further, the menu may be selected depending on the position where the slide bar 32 is tapped. In this case, when the first tapping is detected, the menu contents selected corresponding to the detected position of the slide bar 32 are displayed on the display unit 18 as shown in FIG.

  Further, as shown in FIG. 18, the slide bar 32 is configured by a touch panel or the like capable of displaying, and when tapping is detected, the menu contents selected corresponding to the detected position of the slide bar 32 are displayed on the slide bar 32 itself. You may do it. Thus, when the slide bar 32 is configured by a touch panel, the adjustment bar 40 and the like can be displayed on the slide bar 32 itself.

  In the above embodiment, it is assumed that the user touches the slide bar 32 with one finger. However, when the first position is determined or the second position is determined, it may be allowed to touch with two fingers. When two fingers are detected, the MPU unit 26 uses the middle as the first position or the second position, and performs a change process different from the case where one finger is detected. For example, it is possible to perform a special process such as changing the change speed and the change amount to double that of a single finger.

  In addition, as shown in FIG. 19, a display that can be used by switching between portrait and landscape is also available. In this case, the MPU unit 26 receives the output of a sensor (not shown) that detects vertical / horizontal switching, and as shown in FIG. 19, the shuttle mode adjustment bar so as to match the direction of the slide bar 32. 44. It is preferable to change the display direction of the menu or the like.

  In the above embodiment, the slide bar 32 is provided on the surface of the display device. However, according to the present invention, unlike the conventional slide pad, it is not necessary to visually confirm the position of the finger or the position of the middle point. Therefore, as shown in FIG. Good. In this case, it is preferable to provide the slide bar 32 from end to end of the housing. In addition, it is preferable to provide, on the surface of the slide bar 32 or in the vicinity thereof, a protrusion that can be sensed by touch, such as a protrusion shown in an enlarged manner in FIG. In this embodiment, the width of the protrusion is maximized at both ends of the slide bar 32 and is minimized at the center. Thereby, it is possible to confirm which part of the slide bar 32 is being touched.

  In the above description, the back surface is illustrated as an area other than the viewable area (area where the user who is using the display can normally visually recognize). However, the slide bar 32 may be provided on the side surface or the bottom surface as an area other than the visible area.

  Further, as shown in FIG. 21, the display unit 18 may be a touch screen and may replace the slide bar 32. In this case, after the menu is selected, the shuttle mode adjustment bar 44 can be displayed around the point (first position P1) that the user has long pressed.

In the above embodiment, the slide bar 32 is provided on the main body side of the display device. However, the same processing can be performed by providing the slide bar 32 on the side of the remote control device that can send a signal to the display device. In this case, the adjustment bar 40, the shuttle mode adjustment bar 44, and the like may be displayed on the display unit 18 of the display device, but may also be displayed on the display on the remote control side.

2. Second Embodiment In the first embodiment, the number of parameters to be changed is one. In the second embodiment, a plurality of parameters can be changed simultaneously.

  Since the hardware configuration and the like are the same as those in the first embodiment, a description thereof will be omitted. In this embodiment, a pad 33 as shown in FIG. 22 is used instead of the slide bar 23. The pad 33 detects the position of the finger in the X direction and the Y direction and outputs it to the MPU unit 26.

  The MPU unit 26 controls the first parameter by the X direction component of the detection position, and controls the second parameter by the Y direction component. Each control method is the same as in the first embodiment.

  FIG. 23 shows a display example of the adjustment bars 40X and 40Y in the jog mode. The adjustment bar 40X indicates a first parameter controlled by the X component, and the adjustment bar 40Y indicates a second parameter controlled by the Y component.

  FIG. 24 shows a display example of the adjustment bars 40X and 40Y and the shuttle mode adjustment bars 44X and 44Y in the shuttle mode.

  According to this embodiment, two parameters can be adjusted simultaneously.

  Further, as described above, the flat pad 33 is not provided, and a plurality of slide bars 32 as in the first embodiment are provided, and a plurality of parameters can be adjusted simultaneously by touching each slide bar 32 with a finger. You may do it.

  Instead of providing the pad 33, all or part of the display unit 18 may be used as a touch screen instead of the pad.

  Further, a pad 33 as shown in FIG. 25 may be used. The pad 33 outputs the distances X, Y, and Z to each side for the finger position P to the MPU unit 26. Therefore, the MPU unit 26 can control three parameters at the same time.

Furthermore, two or more parameters may be controlled using the slide bar 32 used in the first embodiment. For example, when the first parameter is changed, in order to obtain a good result (for example, an appropriate image), it may be preferable to change the second parameter at the same time. In such a case, simultaneously with changing the first parameter, the MPU unit 26 calculates an appropriate second parameter for the first parameter and changes the second parameter at the same time.

3. Others In the above embodiments, display parameters and audio parameters of the display have been described. However, it can also be used for fast-forwarding and rewinding of moving images such as DVDs.

  Moreover, it can generally be used for parameter adjustments other than display parameters and audio parameters. That is, it can also be used for parameter adjustment in a device other than the display device.

  In each of the embodiments described above, the user's finger is used as the detection target. However, an object other than a finger may be detected as an object. For example, the above processing may be performed using a line of sight, a stylus pen, or the like as a detection target.
