Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote commander using infrared rays or the like, or an electronic device that can be operated by an operation section provided in the device body.

[0002]

2. Description of the Related Art Electronic equipment, which is capable of various adjustments and the like by a remote commander using infrared rays or radio waves, is widely used, and is known as a television device, a monitor device, a VTR, a CD player, or the like. ing. In these remote control methods, a command signal is set so that the operation of the remote commander on a certain device does not cause another device to react and malfunction. Further, these electronic devices are also provided with an operation unit in the device body, and various adjustments can be performed from the device body side as in the remote commander.

By the way, the number of various operation keys arranged on the remote commander or the operation section is kept to a minimum so as not to give the user a complicated impression. That is, when performing various adjustments, a predetermined operation key is used to display an operation menu generated by the graphic generator on the screen, and each of the contrast, brightness, chroma, phase, aperture, etc. displayed on the operation menu is displayed. It is possible to select an item and perform image quality adjustment and various settings. Further, for example, in a television receiver to which a device such as a VTR is connected to the outside, when an operation of selecting a broadcast channel is performed while an external input channel is selected, for example, Japanese Patent Laid-Open No. 60-8
As shown in No. 9178, a warning is displayed that the current broadcast channel cannot be selected by either the remote commander or the operation unit.

[0004]

By the way, as described above, various adjustments and setting operations can be performed by the operation menu displayed on the display unit, and both the remote commander and the operation unit have operation menus. Since the display functions are the same, the operation items of the operation menu displayed by operating the respective menu display keys are the same. However, for example, when there is an operation item that can be performed only by the operation unit provided in the device body, when the operation item is displayed in the operation menu, inconvenience occurs. That is, operation items that cannot be operated from the remote commander are also displayed in the operation menu, and the user can select the operation item from the remote commander.
Since the settings such as the numerical values of the operation items cannot be changed from the remote commander, the user will be confused during operation. The same problem occurs when an operation item that can be operated only from the remote commander is to be executed from the operation unit. In this case, for example, a dedicated operation key may be provided only on the operation unit so that a predetermined setting operation can be performed only by the operation key. However, since the number of operation keys increases, the operation unit becomes complicated. Therefore, the operability will decrease.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and displays a menu screen by an on-screen display function and serves as a remote commander or device as an operating means. In an electronic device capable of adjusting / setting operations of operation items displayed on the menu screen by an operation unit provided on the main body, adjustment is made only by an operation means of either the remote commander or the operation unit. An electronic device is configured such that, when an operation item that can be set / set is selected by the other operation unit, the operation item is displayed in a mode different from that of other operation items.
Further, a message indicating that the operation item is inoperable is displayed.

[0006]

According to the present invention, when an operation item that cannot be executed by the remote commander is to be executed on the menu screen, the display mode of the operation item can be changed and displayed. The display makes it possible to know that the operation from the remote commander is impossible. Further, when trying to execute the operation item, it becomes easy to determine that the operation means is changed from the remote commander to the operation unit provided in the device body, and the operability is improved. .

Embodiments of the electronic equipment of the present invention will be described below with an example in which a television receiver, in particular, a large number of television receivers 1 are arranged in a stack and used as a multi-monitor device as described later. I will give you an explanation.

The video circuit system of each television receiver 1 is
It is configured as shown in FIG. Reference numeral 2 denotes a tuner / VIF for selecting a broadcast wave received by the antenna A and amplifying an intermediate frequency of the selected broadcast wave. An image processing circuit unit 3 performs a predetermined process according to a tuner / VIF 2 selected by the switch SW or an image signal supplied via the video input terminal tv, and outputs an R signal / G.
Signal / B signal is demodulated and output. Further, the image processing circuit 3 also performs image quality variable adjustment such as brightness and contrast. 4 is OSD (on screen
It is a display) and superimposes the menu screen and the like generated by the graphic generator 5 on the video signal output from the video processing circuit 3 and supplies the superposed image to the CRT 6.

Reference numeral 7 denotes a sync separation circuit, which extracts a horizontal sync signal H and a vertical sync signal V from an input video signal and supplies them to a deflection circuit 8. The deflection circuit 8 generates horizontal and vertical deflection currents in accordance with the horizontal synchronizing signal H and the vertical synchronizing signal V, and respectively generates a horizontal deflection coil 9H and a vertical deflection coil 9V.
To perform image scanning. Reference numeral 10 denotes a command receiving unit that receives and demodulates various control commands output from the remote commander RC, and supplies the control unit 12 with a command receiving unit. Reference numeral 11 denotes an operation unit provided in the main body of the television receiver 1, and a command receiving unit. Similar to 10, various control commands are supplied to the control unit 12. Remote Commander R
C, the operation section 11 is provided with various operation keys having substantially the same functions as described later with reference to FIG.

Reference numeral 12 denotes a control section formed by a microcomputer including a CPU, ROM, RAM, interface section and the like. The control unit 12 determines whether various control commands to be input are input from the remote commander RC via the command receiving unit 10 or input from the operation unit 11. 13 indicates a memory,
Unit I individually provided to each device as described later
D, and a set ID that is set by the user to specify the operation target by the remote commander. Holds a non-volatile RAM, EEP-ROM, etc. so that data will not be lost even when the power is turned off. Alternatively, the power source backup means may be added to the D-RAM or S-RAM.

FIG. 2A is a diagram showing an example of various operation keys provided on the operation unit 11, and FIG. 2B is an example showing various operation keys provided on the remote commander RC. The operation keys for performing the same operation in these figures will be described with the subscript a attached to those provided on the operation unit 11 and the subscript b attached to those provided on the remote commander RC. 21 in these figures
(A, b) power key, 22 (a, b) volume up /
Down key, 23 (a, b) are channel up / down keys, 24 (a, b), 25 (a, b) are VT, for example.
An external input channel selection key such as R. Also, 26
(A, b), 27 (a, b), 28 (a, b) are keys for menu operation, for example, the menu key 26
(A, b) are keys for executing menu display, select keys 27 (a, b) are keys for selecting operation for moving the cursor, pointer, etc. in the menu, enter key 2
8 (a, b) is a key for executing the selected content.

In this embodiment, the remote commander RC is provided with an ID mode ON key 29, an ID mode OFF key 30, and an ID mode set key 31 as keys for the ID operation mode. The contents of these commands will be described later. Further, the remote commander RC is provided with a direct channel key (numerical key) 32.

When a certain key among various kinds of keys provided in this way is pressed, the microcomputer inside the remote commander RC reads the command data corresponding to the key from the ROM or the RAM and uses the predetermined carrier. Modulate. Then, the light emitting diode is turned on / off by the modulation signal and a command signal is output as an infrared modulation signal.

Such an infrared command signal is received by a light receiving element (for example, a phototransistor) in the command receiving section 10 of the television receiver 1, converted into an electric signal, demodulated and supplied to the control section 12 as command data. Will be decoded.

The control unit 12 controls each unit according to the content of the decoded command signal. For example, in this embodiment, when a command signal is supplied by the menu key 26 (a, b), a menu screen as described later with reference to FIG. 13 is displayed, and the menu item selected according to the menu screen is displayed. By controlling the video processing unit 3 and the like, the coefficient variable setting of the adjustment circuit is performed.

Here, the television receiver 1 thus constructed has, for example, nine television receivers 1a to 1a.
When the multi-monitor device is arranged as a stack 1i as shown in FIG. 3, normally, the command signal from the remote commander RC is received by all the television receivers 1a to 1i. For example, when the power key 21b is pressed on the remote commander RC in front of this multi-monitor device, the power of all the television receivers 1a to 1i is turned on.

However, in such a multi-monitor device, it is important that there is no difference in image quality between the television receivers 1a-1i. Therefore, the image quality is adjusted individually in each device so that there is no difference in the image quality between the television receivers 1a to 1i.

In this embodiment, for example, in such a case, the remote commander RC allows only a specific television receiver to be operated, thereby facilitating the adjustment work. Needless to say, not only the image quality adjustment but also all the operations that can be executed by the remote commander RC can be individually executed.

Therefore, in the memory 13 of the television receiver 1, the unit ID individually given to each television receiver 1 and the set ID set by the user for designating the device to be operated. Is memorized. First, as the unit ID, for example, ID numbers 1 to 255 are randomly assigned when the television receiver 1 is shipped from the factory. This is because each of the television receivers 1a to 1i should have a different unit ID as much as possible, even if the television receivers 1a to 1i are used as a multi-monitor device by using some nine television receivers 1 as shown in FIG. is there.

As described above, each of the television receivers 1a-1
Only a specific television receiver is set as a remote commander RC by setting an individual unit ID to i.
The ID operation mode of the present embodiment, which is operated by, can be executed.

This operation will be described below with reference to FIGS. 4 and 5 are flowcharts showing the processing of the control unit 12, and FIGS. 6 to 11 show examples of display states of the television receivers 1a to 1i. Note that, in FIG. 4 and FIG. 5, for simplification of description, the main processing, that is, I
Only the processes related to the D operation mode are shown.

As shown in FIG. 4, when the control unit 12 receives the command signal, the process proceeds from step F101 to F102. Here, the user can use each of the television receivers 1a ...
The user wants to know the unit ID assigned to 1i and performs a predetermined operation, for example, the menu key 26b and the select key 27.
If the operation for designating the unit ID display processing as the processing in the menu is performed using the b and enter keys 28b (note that the remote commander RC is provided with a dedicated key for the unit ID display operation, of course). The unit ID number may be displayed in step F103. This processing is to be displayed as an OSD on the CRT 6 of the television receiver 1 (display of various ID numbers described later is also the same).

Now, suppose that the television receivers 1a to 1i are assumed.
However, the unit ID is "015" and "002" respectively
"176""250""037""016""010"
If the numbers "096" and "052" are given, each of the television receivers 1a to 1i displays the unit ID stored in the memory 13 in response to the unit ID display operation from the remote commander RC. Therefore, the OSD display is performed as shown in FIG. 6 on the multi-screen by each of the television receivers 1a to 1i. This allows the user to confirm the unit ID of each of the television receivers 1a to 1i.

As will be described later, the unit ID can be individually changed by the user from the operation unit 11.
Therefore, for example, if there is a television receiver with the same unit ID, rewrite the same unit I.
It can be reset so that D does not exist. However, since the unit ID is randomly given as described above and the television receiver 1 is shipped, it is unlikely that the unit ID needs to be rewritten in this way. Although not particularly required, the unit ID of each of the television receivers 1a to 1i is set to "00" as shown in FIG.
By rewriting it into a serial number that is easy to remember, such as 1 ”,“ 002 ”, ...,“ 009 ”, it becomes easier to use thereafter.

The unit ID may be variably set and stored by a mechanical switch, for example.
For example, a mechanical switch (which may be any type of switch) capable of changing 1 to 256 is provided on the rear surface other than the operation unit 11 of the television receiver 1, for example, and a unit ID is stored depending on the switch state. Alternatively, it may be changed by a switch operation.

When the command signal is received and it is not the unit ID display operation, the process proceeds to step F104 to determine whether or not the ID operation mode is currently set. If it is not the ID operation mode in the normal state, it is determined whether the received command signal is the ID operation mode ON command, that is, whether the ID mode ON key 29b is pressed (F105). If the command signal is not in the ID operation mode and the command signal is not the ID operation mode ON command, the process proceeds to step F106 to perform normal processing. That is, predetermined control is performed according to the command content. Looking at this as a whole multi-monitor device, each television receiver 1
The same operation is executed in all of a to 1i.

If the command for turning on the ID operation mode is given in step F105, the ID operation mode is turned on (F10
7), the set ID stored in the memory 13 at that time
And the unit ID match (F10
8). The set ID is an ID number set by the user to specify an operation target by the remote commander RC, and is updated every time it is set and held in the memory 13 (that is, held as a last memory).

Now, as the initial value, the set ID number =
If it is stored as "001", when the unit ID is set in each of the television receivers 1a to 1i as shown in FIG. 5, the set ID and the unit ID do not match in any of the television receivers. Therefore, the processing proceeds to step F109 in all the television receivers 1, and the unit ID and the set ID are displayed as shown in FIG. 7, for example. The OSD display of the unit ID and the set ID is displayed as red characters, for example.

The display of the unit ID and the set ID as described above indicates that the ID operation mode is turned on. The red display means the unit ID and set I
The television receiver 1 displaying the non-coincidence state of D does not accept the operation from the remote commander RC during the ON period of the ID operation mode (however, the ID mode ON key 29, the ID mode OFF key 30, the ID mode). Only the set key 31 is accepted and decoded).

If the ID mode ON key 29 is pressed and the process proceeds to step F108 at the time when the set ID is "002", the unit ID and the set ID match only for the television receiver 1b. It will be. Therefore, the steps are performed in the television receiver 1b.
Proceed to F110 to display the set ID and unit ID as blue character characters. At this time, in the other television receivers 1a and 1c to 1i, the process proceeds to step F109, and the set ID and the unit ID are displayed in red. Therefore, only the television receiver 1b is displayed differently on the multi-screen as shown in FIG. Unit ID and set ID
Will be displayed.

Here, the blue display (that is, the unit ID and the set ID match display) means that the television receiver is an operation target by the remote commander RC in the ID operation mode. That is, FIG.
In this state, only the television receiver 1b can be operated.

During the ID operation mode in which the unit ID and the set ID are displayed on the screen as described above, if a command signal is received, the process proceeds from step F104 to step F111. Here, it is determined whether or not the received command signal is applied to the ID mode set key 31, and if it is a command of the ID mode set key 31, a set ID designation (change of set ID) process is performed (F112). This set ID designation processing will be described later with reference to FIG.

If the command is not the ID mode set key 31, it is determined whether the ID operation mode is off, that is, the ID mode off key 30 is pressed (F
113).

If the command is not for turning off the ID operation mode but for operating various other operation keys, is the unit ID = set ID at that time, that is, is the state in which blue display is being performed? Whether or not it is determined (F114), and if the unit ID = set ID, predetermined operation control is executed according to the decoding content of the command signal (F115). If the unit ID is not the set ID, the command signal is not accepted, and no control processing according to the command content is performed (F116).

Therefore, the menu is displayed in the state of FIG. 8 and the operation item "contrast" is selected by the select key 27b.
, The contrast adjustment is performed only for the television receiver 1b, but the contrast adjustment is performed for the other television receivers 1a and 1c-1i even if the command signal is received. In other words, the user can operate only the television receiver 1b by the remote commander RC by setting the set ID in the ID operation mode to "002".

If the command signal received during the ID operation mode is the OFF operation of the ID operation mode, step F113
From F to F117, the ID operation mode is turned off, and the unit ID and set ID display is turned off (F
118). Needless to say, after the ID operation mode is turned off, if a normal operation command signal is received, the process proceeds to step F106, and the process corresponding to the command signal is unconditionally executed.

Here, when the user wants to operate a certain arbitrary television receiver, it is necessary to change the set ID. For example, when the ID operation mode is set to operate the television receiver 1b, the set ID is "0.
In the case of "01" and the state of FIG. 7, the set ID is "0".
02 ”to obtain the state shown in FIG.

Further, after operating the television receiver 1b, if it is desired to operate the television receiver 1e this time, the set ID is changed to "037" and the state of FIG. (Assuming that machine 1e is specified by the set ID, its OSD display will be blue)
I have to

Such a change of the set ID is executed by pressing the ID mode set key 22b in the ID operation mode. That is, this is the process of step F112. The process of step F112 is shown in detail in FIG. First, the ID set mode is set (F200). In this ID set mode, a user's numerical input or enter input is awaited, but in order to present that fact, the OSD display of the set ID may be blinked in the ID set mode. .

Then, in steps F201, F202, F203, the input or ID number input is awaited. The ID number is input as a direct numerical value input or numerical value increment / decrement input by the numerical keys 32 of the remote commander RC or the channel up / down keys 23b. The enter operation is an operation for determining the input numerical value as the set ID, and is, for example, an operation of pressing the ID mode set key 31b again in the ID set mode.

When a numerical value is input, in step F204,
It is determined whether or not the numerical value matches the unit ID number. If they do not match, the OSD is displayed in red with the set value as a set ID number. If they match, the value is displayed in blue as a set ID number.

For example, when the ID mode set key 31 is pressed from the state of FIG. 6 to shift to the ID set mode,
If the user inputs "0", "3", and "7" with the numeric keys 32, the display is as shown in FIG. 9 (however,
Numbers should be blinking as they have not been decided yet). In other words, only the television receiver 1e has a blue OSD display because this input numerical value matches the unit ID, and the other television receivers 1a to 1d and 1f to 1 are displayed.
i is a red OS because the input numerical value does not match the unit ID
It becomes D display.

When the user desires to operate the television receiver 1e, the enter operation, that is, the ID mode set key 31 is pressed here. Then, the process proceeds to step F207, rewrites the memory 13 with the input numerical value as a new set ID number, and ends the ID set mode (F208).
Returning to the routine of FIG.

When the remote commander RC is operated in the ID operation mode, the television receiver 1e proceeds to step F115 in response to the reception of the command signal,
Although the operation according to the operation is executed, the command signal is ignored in the other television receivers 1a to 1d and 1f to 1i in step F116. That is, it is possible to operate only the television receiver 1e designated by the set ID.

By the way, as described above, the unit ID in each television receiver can be set only from the operation unit 11 of the television receiver 1, and cannot be set from the remote commander RC. However, the menu screen displayed on the CRT 6 is the operation unit 11
It is the same even when displayed by operating the (menu key 26a) or the remote commander RC (menu key 26b). That is, the operation items that cannot be set from the remote controller RC are displayed in the same manner as the settable operation items.

Therefore, in the present invention, when the remote commander RC attempts to set, for example, a unit ID that cannot be set from the remote commander RC as described above, a display mode of operation items that cannot be set on the menu screen. To indicate that the setting cannot be changed from the remote commander RC.

This operation will be described below with reference to FIGS. FIG. 12 is a flowchart showing the processing of the control unit 12, and FIGS. 13, 14, and 15 are diagrams showing an example of the display state of the television receiver 1. 13,
In FIG. 14, C is a cursor indicating a setting item to be selected.

By pressing the menu key 26a or 26b to perform various adjustments / settings, the CRT 6 is caused to display a menu screen as shown in 13 (a) (F301). On the menu screen displayed here, operation items such as "contrast", "color", "brightness", and "unit ID" are displayed.
Then, for example, when adjusting the contrast, "contrast" is selected by the select key 27a or 27b (F302). The keys from steps F301 to F302,
The operation is the same for both the operation unit 11 and the remote commander RC. When the operation item is selected in step F302, the enter key 28a or 2 is pressed to determine the operation item.
Press 8b (F303).

Then, the control unit 12 detects whether the enter key 28 (a or b) of the operation unit 11 or the remote commander RC is pressed (F304). Here, if it is determined that the remote commander RC has operated,
In step F305, it is determined whether or not the selected operation item can be set from the remote commander RC. Since "contrast" which can be adjusted from the remote commander RC is selected here, the menu screen shifts to the "contrast" adjustment screen as shown in FIG. 13B, for example. As shown in FIG. 7C, the contrast adjustment value can be changed from "30" to "45" (F306).

Further, in step F302, as shown in FIG.
When the "unit ID" is selected as shown in (a), it is determined in step F305 that it is impossible to set from the remote commander RC,
For example, as shown in FIG.
] To indicate that the setting is not possible (F307). In addition to changing the display mode of the set numerical value as shown in FIG. 14B, a message such as “Remote control cannot be used” is displayed as shown in FIG. 14C. Good.

When the enter key 27a of the operation unit 11 is input in step F303, the process proceeds from step F304 to step F308. In this step F308, since there are no unsettable items in this embodiment, the selected operation item can be changed. For example, when “Contrast” is selected, the settings shown in FIGS.
It can be performed in the same manner as the case described in. If "Unit ID" is selected in step F302, the setting screen shown in FIG. 15A is displayed,
As shown in FIG. 7B, the unit ID is “00
It is possible to change from "1" to "777", for example.

If the enter key 27a of the operation unit 11 is operated in the state shown in FIG. 14B, the settable display shown in FIG. 15B is displayed and the unit ID can be changed. It becomes possible and the unit ID can be changed by the operation unit 11. When the enter key 27b of the remote commander RC is operated in the state shown in FIG.
As shown in (b) or (c), the display becomes impossible.

As described above, in the present embodiment, for example, the unit ID that can be changed only by the operation unit 11 is used.
When changing from the remote commander RC, changing the display mode on the menu screen reveals that setting is not possible from the remote commander RC, and confusion in operation can be avoided. become. In this embodiment, the operation command that can be adjusted / set only in the operation unit 11 is the remote commander R.
Although the example of performing the operation by C has been described, for example, when the operation unit 11 attempts to execute an operation item that can be adjusted / set only by the remote commander RC, the display mode of the operation item can be changed. Is also possible. Further, in addition to changing the display mode of the menu screen, for example, the electronic device body is provided with a light emitting unit such as an LED, and the light emitting unit is lit or blinked for adjustment / adjustment.
It may be possible to indicate that the setting cannot be executed.

Further, the present invention is not limited to the television receiver shown in the embodiments, but can be applied to a device such as a monitor device, a VTR and the like, which can be operated by an operation unit and a remote commander.

[0055]

As described above, the electronic apparatus according to the present invention uses the operation section provided in the apparatus body and the operation means such as the remote commander to select various operation items displayed on the menu screen. When adjusting / setting, using the remote commander, if you try to adjust / set an operation item that can be adjusted / set only with the operation unit among the displayed operation items, the operation The display mode of the item can be changed, and a message that the operation cannot be performed can be displayed. Therefore, in such a case, the user can understand from the displayed operation item or message that the selected operation item is an operation item that cannot be adjusted / set by the operation means currently used. That is, it is easy to understand that adjustment / setting can be performed by changing the operation means, and there is an advantage that operability is improved.
