Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system suitable for an audiovisual system and the like.

[0002]

2. Description of the Related Art In recent years, VTRs, television receivers, C
A / V equipment such as D player, air conditioner,
Various electronic devices such as lighting devices can be remotely operated using a remote commander. By the way, since it is troublesome for a user to use a dedicated remote commander for each type of device, it is preferable that one remote commander can perform operations of a plurality of types of electronic devices.

Therefore, the present applicant has previously proposed that, as a prior art,
For example, a method has been proposed in which various operation images are displayed on the screen of a CRT monitor or the like, and various devices can be operated by selecting them with a pointer or a cursor.

For example, when connecting a control unit when connecting a laser disk player or VTR as an AV system to a CRT monitor, for example, when operating the laser disk player, FIG.
As described above, various operation images SD and the pointer P for selecting them can be displayed on the CRT monitor screen.

Then, for example, when a command code serving as position displacement information is output from the remote commander, the pointer P is moved accordingly, and when the pointer P is on a certain operation image, the remote commander serves as enter information. When the command code is supplied, the command code corresponding to the operation image is output from the control unit to a predetermined device.

For example, when an enter operation is performed in the state shown in FIG. 15A, a command code indicating the beginning of the next track is output from the control unit to the laser disc player. Then, the laser disc player receives the command code and executes the next track cue search operation in accordance with the command code.

In this system, for example, as the operation input means by the remote commander, it is sufficient that only the operation for moving the pointer P and the enter operation can be performed, and the simplicity of the operation is greatly improved.

[0008]

However, when an operation character image is displayed on the monitor screen and is used for the operation as described above, the character image from the laser disc player, the VTR, the TV tuner, or the like is displayed. Has a problem in that it becomes difficult to see or disappears when it is superimposed on the operating character image.

For example, when a track search operation is performed in a laser disc player, the laser disc player outputs a character image OSD such as "CHAPTER 7" to indicate a chapter number (track number) for search. Figure 15
As shown in (b), the operation image SD and “CHAPTER
The character image OSD “7” may overlap and the character image OSD may become very difficult to see. In particular,
If the operation image SD and the character image OSD overlap each other in the same color portion, the character image OSD cannot be seen at all.

Further, as shown in FIG. 16 (a), an operation image SD for channel switching of the TV tuner is displayed. For example, when the pointer P is in the channel up position as shown in the figure, the enter operation is performed. The TV tuner will be switched in the up direction. Here, when the channel is switched, the TV tuner often outputs a new channel number as a character image for a predetermined time, but in this case also, the operation image SD and the new channel number are used. For example, if the character images OSD showing a numerical value of “6” overlap on the screen as shown in FIG. 16B, this also becomes very difficult. In addition, the same applies to the case of a character image generated for adjusting brightness, sharpness, etc. of the monitor device.

The operation image SD and the character image O
It suffices to set the SD so that it is displayed at a position where it does not overlap, but in reality, the display output position of the character image OSD differs depending on various manufacturers and models, so this is always avoided to display the operation image SD. It is actually very difficult to do.

[0012]

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to solve the problem that a character image formed by various devices is difficult to see due to an operation image formed by a control system.

Therefore, operation input means (remote commander, touch panel operation unit, etc.) capable of transmitting or outputting positional displacement information or enter information as input information at least in accordance with an operation in a wired or wireless manner and various command codes are stored. Display control for displaying and outputting an operation image and a position designation image corresponding to all or a part of various command codes stored in the storage means, based on the storage means and the input information transmitted from the operation input means. Means, and a command generating means for reading out a command code corresponding to the operation image designated by the position designation image from the storage means based on the input information transmitted from the operation input means, and outputting the command code. Means for transmitting the command code to the operated device or the operated unit by wire or wirelessly In addition to constructing a control system, the display control means, in accordance with the instruction of the output operation of the command code from the command generation means by the input information transmitted from the operation input means, the operation image and the position designation image. Configure so that the display output of can be stopped.

Particularly, when the command generation means instructs the output operation of the predetermined command code by the enter information transmitted from the operation input means, the display control means continues to input the enter information. In the meantime, the display output of the operation image and the position designation image can be stopped.

Alternatively, the display control means, when the enter information transmitted from the operation input means instructs the output operation of the predetermined command code from the command generation means, a predetermined period from the time when the enter information is input. Enables to stop the display output of the operation image and the position designation image.

Further, the display control means suspends the display output of the operation image and the position designation image in response to the instruction of the output operation of the command code from the command generation means based on the input information transmitted from the operation input means. In the meantime, the position displacement information from the operation input means for displacing the display position of the position designation image is not accepted as a valid operation.

[0017]

[Function] While the position displacement information is transmitted and the pointer is moved, the user must operate while confirming the operation image, but when the enter operation is performed to confirm the operation, the operation is performed. The user does not need to confirm the operation image during the operation. Therefore, there is no problem even if the operation image and the position designation image are erased from the screen during this period.

Further, when the user has transmitted the position displacement information while the operation image and the position designation image are erased in this way, it is not appropriate to move the position designation image accordingly. Therefore, if this is an invalid operation, the operation will not be confused for the user.

EXAMPLES Examples of the present invention will be described below. 1 and 2 show a configuration of a remote control system according to an embodiment, and FIG. 1 is an explanatory view of an example of an AV system adopting the remote control system of the embodiment, FIG.
FIG. 3 is a block diagram of a remote control system.

In FIG. 1, 10 is an AV selector amplifier, 61 is a VTR, 62 is a CD player, 63 is a TV tuner, 64 is an LDP (laser disc player), 7
Reference numeral 0 represents a monitor device, and 71 represents a speaker.

The VTR 61, the CD player 62, the TV tuner 63, and the LDP 64 each have an audio / video signal output connected to the AV selector amplifier 10, and the audio / video signal selected by the AV selector amplifier 10 is output from the monitor device 70 and the speaker 71. Connected to be output. In addition, the VTR 61, the CD player 62, the TV tuner 63, and the LDP 64 have infrared receiving sections 61a and 61a, respectively.
62a, 63a, and 64a are provided, and normally, they can be remotely operated by infrared command signals output by dedicated remote commanders. However, in this embodiment, the operation of each device can be executed by one remote commander R.

The remote control system according to the present embodiment comprises the remote commander R and a control unit (described in FIG. 2) built in the AV selector amplifier 10. The remote commander R is, for example, x. , As long as it can output only the positional displacement information on the y-coordinate and the enter information, as shown in the figure, only the shuttle ball S is provided as the operation unit, an angular velocity sensor, an acceleration sensor, or the like. It can output position displacement information, or can output trackball rotation information like a mouse in a personal computer (not shown), can output operation direction information with a joystick, and has direction keys such as 4 or 8 directions. It can be anything that you eat. That is, it is not necessary to provide a large number of operation keys. The signal transmission method may be any of infrared rays, radio waves, or wire transmission.

For example, in the case of the remote commander R using the shuttle ball S, when the user rotates the shuttle ball S, displacement information in the x and y directions is output as, for example, an infrared modulation signal, and when the shuttle ball S is pressed. Allows enter information to be output.

The remote commander R using the angular velocity sensor is constructed as described with reference to FIGS. 3 to 6, for example. FIG. 3 is a block diagram of the internal configuration of the remote commander R using the angular velocity sensor, and 1 indicates a vibration gyro as the angular velocity sensor.

The vibrating gyro has a characteristic that when a rotating angular velocity is applied to a vibrating object, a Coriolis force is generated in a direction perpendicular to the vibration, and the Coriolis force F is expressed as follows. F = 2mvω (m: mass, v: velocity, ω: angular velocity) Therefore, the angular velocity ω
Is proportional to the Coriolis force F, and the rotational angular velocity can be detected by detecting the Coriolis force F.

A driving piezoelectric ceramic 1a and a detecting piezoelectric ceramic 1b are attached to the vibration gyro 1, and an alternating signal which is an oscillation output of the oscillator 2 is applied to the driving piezoelectric ceramic 1a. Vibration gyro 1 in this state
Is rotated in the direction of Ω ₀ , Coriolis force F is applied to the detecting piezoelectric ceramic 1b, and a voltage E is generated.

The minute voltage obtained from the detecting piezoelectric ceramic 1b is amplified by the amplifier 3 and supplied to the A / D converter 4,
It is regarded as digital data. 5 is a CPU 5a and a ROM 5
b shows a control unit formed by a microcomputer having a RAM 5c, and a command signal to be transmitted is stored in the ROM 5b or the RAM 5c. Reference numeral 6 indicates a clock oscillator. Reference numeral 7 denotes an enter key provided as an operation key on the remote commander R as shown in FIG. 1, for example, and operation information of the enter key 7 is also supplied to the control unit 5. The control unit 5 reads out and outputs an enter command from the ROM 5b or the RAM 5c in accordance with the operation of the enter key 7, and supplies it to the transmission unit 8.

Further, the control unit 5 reads an up command or a down command from the ROM 5b or the RAM 5c according to the digital data of the voltage E input from the A / D converter 4, and supplies it to the transmission unit 8. The angular velocity ω applied to the vibration gyro 1 and the generated voltage E have a proportional relationship as shown in FIG. 4, and the control unit 5 converts the input voltage E (digital data) into voltage values Va, Vb, Vc, Vd, for example. By comparing, it is possible to output the command code according to the operation performed on the remote commander R by the user.

For example, the vibrating gyro 1 is arranged in the remote commander R such that the voltage E rises due to the angular velocity when the remote commander R is swung upward, and the voltage E decreases according to the angular velocity when the remote commander R is swung downward. If so, the control unit 5 determines the command code to be generated, for example, according to the flowchart of FIG.

When the enter key 7 is pressed, an enter command is unconditionally generated (F101 → F102). In other cases, the input voltage E (digital data) is converted into voltage values Va, Vb, Vc. , Vd. And V
If c <E <Vd, that is, if the remote commander R is swung upward, the up command is sent to the ROM 5b or R.
Read from AM5c (F103 → F104). Also, Va <E
If <Vb, that is, if the remote commander R is swung downwards, the down command is read (F105 → F106).
. The voltage E input in the control unit 5 is Vb
If ≦ E ≦ Vc, no command code is generated, but this is set as a dead zone so that the command code is not output when the user touches or carries the remote commander R for a while. Is.

The command code thus generated from the control unit 5 is subjected to a predetermined modulation processing in the transmission unit 8 and is output to a predetermined device by an infrared signal or a radio wave. Therefore, as the remote commander R in the remote control system of the present embodiment, for example, as shown in FIG. 6, the vibration gyro 1 is used as the movement information (angular velocity) detecting means corresponding to the vertical direction y and the horizontal direction x in the remote commander R. , 2 units are provided in the orthogonal direction (1x, 1y), the angular velocity ω _x when the remote commander R is swung in the left-right direction is detected, and a left movement command or a right movement command (that is, position displacement information in the x-axis direction) is issued. In addition to the output, the angular velocity ω _y when the remote commander R is swung up and down may be detected and an up command or a down command (that is, position displacement information in the y axis direction) may be output.

In order to configure the remote control system of this embodiment, a remote commander R capable of outputting position displacement information by including such a shuttle ball, trackball, jog shuttle, x, y angular velocity sensor, etc. Corresponding to, the control unit provided in the AV selector amplifier 10 is shown in FIG.

Supply to. As the display contents by the character image, as shown in FIG. 1, an operation image SD showing the operation contents according to various devices and a specific operation image SD among the operation images SD displayed as the position designation image. A display of a finger image indicating the arrow, an arrow, and the like (hereinafter, referred to as a pointer P) is prepared. For example, a plurality of operation images SD are displayed on one screen, and the displayed operation images SD are grouped corresponding to each device, for example. For example VT
Operation images SD for reproduction, recording, stop, fast forward, rewind, etc. are set as a group of operation images SD for R61, and these are displayed at the same time. The position designation image may be in the form of a cursor instead of the pointer P, or a method in which the frame of the operation image is moved, or only the operation image shown is changed in other colors.

ROM 23b or RA in the control unit 23
In the M23c, in addition to control data for the functional portion as the AV selector amplifier, various command codes for an electronic device such as a VTR 61 connected to the AV selector amplifier or an external electronic device that has no relation to each other are stored. However, when one of these command codes is designated on the screen by the user's operation of the remote commander R, which will be described later, the command code is read out and supplied to the infrared transmitter 26. Alternatively, the read command code is supplied to the terminal 27 and wired to a predetermined external device or internal circuit system. If a system bus line is constructed between the devices, command transmission may be performed by the bus.

In the infrared transmitting section 26, the supplied command code is subjected to a predetermined modulation process and transmitted as an infrared signal to the outside of the device. The infrared transmitter 26 is provided as an omnidirectional infrared output unit, as shown in FIG. 1, so that the infrared signals output from the infrared transmitter 26 are various types arranged around the AV selector amplifier. It can be received by the infrared receiver in the electronic device (VTR 61 or the like). It should be noted that a command code transmission section using radio waves may be provided instead of the infrared transmission section or in combination therewith.

Reference numeral 28 denotes a mode operation unit for executing an operation mode (operation image deletion mode) for switching control of the image switching unit 15 for the user to specify, for example, the mode operation unit 28 is turned on. In this case, the operation image erasing mode is controlled. The switching control of the video switching unit 15 is executed according to the switching control signal Y _S output by the graphic controller 25 based on the signal from the control unit 23. For example, when the switching control signal Y _S is at H level, the terminal T _g is connected and the graphic controller 25
Is output, and when the switching control signal Y _S is at the L level, the terminal T _t is connected and the video from the video input switching unit 14 is output.

Therefore, when an image is output from the VTR or the like, the CRT scanning is performed by the graphic controller 25.
Character image (operation image SD, pointer P)
Is set so that the switching control signal Y _S becomes H level when the area is to be output, and the switching control signal Y _S becomes L level when scanning the other areas, the image switching unit By switching to 15 at high speed, the operation image S
Superimpose display of D and pointer P is made.

The operation of the remote control system thus configured will be described below with reference to FIGS. 7 to 14. FIG. 7 is a flowchart showing a process executed by the control unit 23 based on the position designation information (x, y displacement information, enter) transmitted from the remote commander 1.

As described above, the ROM 23b or the RAM 2
Although command codes for performing various operations on various devices are stored in 3c, operation images corresponding to these are grouped for each device. For example, in the present embodiment, for the sake of explanation, reproduction for the VTR 61 is performed. Various operation images corresponding to various command codes such as stop, record, and C, C
Various operation images corresponding to various command codes such as play and stop for the D player 62, various operation images corresponding to command codes such as channel switching for the TV tuner 63, and various command codes such as play and stop for the LDP 64 It is assumed that various operating images to be operated and operating images corresponding to command codes such as input switching to the AV selector amplifier and volume are switched and displayed.

In the operation of the embodiment described below, the AV
The selector amplifier 10 is configured to easily perform an operation related to an input selected device, and a group of operation images SD related to the currently input selected device is displayed as the operation image SD. For example, if the VTR is selected in the audio input selector unit 11 and the video input selector unit 14, the operation image SD regarding the VTR operation is first displayed. Then, at this time, the pointer P is obtained from the x and y displacement information from the remote commander R.
Is moved on the screen, and a certain operation image SD (for example, VT
When the enter command is supplied from the remote commander R at the position indicated by (R play), the command code ("VTR play") corresponding to the entered operation image is read from the ROM 23b or the RAM 23c, It is output from the infrared transmission unit 26. Hereinafter, the operation when the operation information by the remote commander 1 is input will be described based on the flowchart of FIG. 7.

It is assumed that the LDP 64 is input and selected in the AV selector amplifier 10 when the AV selector amplifier 10 is turned on. The control unit 23 first sets the switching control signal Y _S = L via the graphic controller 25 (F
201). Then, the operation image data is set in the graphic controller 25 according to the current input function (F202). At this time, the input function is LDP6
Since it is set to 4, the data of the operation image for LDP64 is set. However, since the switching control signal Y _S = L at this time, the operation image SD is not displayed, and the reproduction signal from the LDP 64 selected as an input function is displayed as a video signal on the monitor device 70. It is supplied and, for example, an LDP reproduction image as shown in FIG. 8 is displayed.

Here, for example, when the user operates the remote commander R and some command code is transmitted and taken in by the control unit 23 from the infrared reception unit 22, the control unit 23 causes the terminals Tt and Tg of the video switching unit 15 to operate. The high-speed switching control is performed so that the output of the graphic controller 25 is superimposed on the video signal from the video input selector section 14 and supplied to the monitor device 70. For example, as shown in FIG. 9, a pointer P and an LDP64
The operation image SD is displayed. That is, as shown in FIG. 7, when the command code is input (F203), the control unit 23 resets the timer and starts counting (F
204), the video switching unit 15 executes the high-speed switching operation by the switching control signal Y _S (F205), and the operation image SD regarding the current input selection device is displayed.

The timer count in step F204 is
The display of the operation image SD and the pointer P is erased when unnecessary, and after some command is finally transmitted from the remote commander R (that is, the switching control signal Y _S
During the high speed switching operation by), the operation image SD and the pointer P are erased when no command is transmitted for a certain time.
(F214, F215, F216,) is a process for eliminating the inconvenience caused by the operation image SD and the pointer P being forever displayed on the screen unnecessarily.

Next, it is determined whether the input command code is an enter command (F206). If it is not an enter command, since it is x, y displacement information, the pointer P is moved on the screen accordingly (→ F217).

For example, the pointer P is moved on the screen as shown in FIG. 9. This is because the position of the new pointer P is calculated according to the x and y displacement information, and the screen is moved to the calculated position. The control unit 23 moves the pointer P upward.
Sends data to the graphic controller 25, and realizes movement on the display.

For this purpose, the CPU 23a has an xy coordinate system corresponding to the screen of the monitor device 70,
Thereby, the position of the pointer P, the movement, and the operation image S
The correspondence with D is determined. That is, as shown in FIG. 10, a coordinate system of, for example, 255 dots in the x direction and 192 dots in the y direction is constructed corresponding to the display screen, and the position P _{0 of the} pointer P is grasped as the coordinate value. Then, when the x, y displacement information is input, the x, y displacement information is added to the coordinate value of the position P ₀ of the pointer P until then, and the position of the new pointer P is calculated.

For example, the current position P ₀ of the pointer P is xy
When the coordinates are (x, y) = (128, 66), +5 as displacement information in the x direction from the remote commander R.
If a numerical value of +30 is sent as displacement information in the 0 and y directions, the position P ₁ of the new pointer P is (x,
y) = (178,96) is calculated, and this data is sent to the graphic controller 25, and the pointer P is moved to the position P ₁ on the screen. In addition, when x <0 when adding the x and y displacement information, x = 0, x>
When 255, it is assumed that x = 255, and y <0.
If y = 0, and y> 192, y
= 192.

By grasping the position of the pointer P in such a coordinate system, when the user performs an enter operation from the remote commander R and an enter command is input to the control unit 23, each operation image is displayed. Since the display position of the SD is also grasped by the numerical value indicating the area on the xy coordinates in the CPU 23a, the operation image selected (enter) can be discriminated by the coincidence of the coordinate values.

By such a moving operation of the pointer P,
For example, as shown in FIG. 11A, the pointer P is LDP6.
It is assumed that the operation image SD for 4 has been moved to the position of the next track cue operation.

Here, when the user performs an enter operation from the remote commander R and inputs an enter command to the control unit 23, the enter operation is not a menu enter (described later) but also an external device (in this case, L
Since it is for DP64), the processing is performed at step F2.
Go to 09. Here, it is determined whether the operation image deletion mode is on or off. The operation image deletion mode is set by the user using the mode operation unit 28 as described above.

If the operation image erasing mode is off, the process directly proceeds to step F211, and the operation image SD in which the position of the pointer P and the display position match, that is, the next track cue operation is selected, and the LDP 64 is selected. The command code for locating the next track is ROM23b or RAM
23c, and the LDP6 from the infrared transmitter 26.
4 is transmitted. In this case, the screen state of the monitor device 70 remains as shown in FIG. (If LDP6
Even if the character image is output from 4, the operation image SD
May not be visible when overlapping)

On the other hand, if the operation image erasing mode is ON, the process proceeds to step F210 to set the switching control signal Y _S to L level. That is, the superimpose state is canceled. Then, in step F211, the command code for locating the next track to the LDP 64 is transmitted. Therefore, the operation image SD and the pointer P are erased on the screen. Here, when the LDP 64 receives the command code and performs the next track cue operation, the character generator in the LDP 64 outputs a character image OSD such as "CHAPTER 7" for displaying the track number of the search target. Come on.

At this time, since the operation image SD and the pointer P are erased, the character image OS "CHAPTER 7" is displayed on the screen as shown in FIG. 11 (b).
Only D is displayed, and this display does not become difficult to see or disappear.

The state of FIG. 11 (b) is continued until the user finishes the enter operation (F212), and in this state, the control unit 23 again performs the high speed switching operation by the switching control signal Y _S , that is, the super operation. Return to the Impose state (F214),
The state of FIG. 11A is restored.

By doing this, the user can
The operating states of 64 external devices can be confirmed well, and after the end of the enter operation, the operation image SD and the pointer P are again displayed.
The required operation can be performed according to.

During the enter operation, that is, while the operation image SD and the pointer P are erased, the process does not proceed to step F217, and the pointer P is not moved at all. For example, in the remote commander R using the angular velocity described above, the operation image SD and the pointer P
Even if the user inadvertently shakes the remote commander R and the X and Y displacement information is output when is deleted, the pointer P is not moved, which is convenient. Further, it is not necessary for the user to keep the state as it is (the state in which the remote commander is kept facing the device) so that the remote commander R does not move during the enter operation. In particular, when the enter operation is continuously performed for a certain period of time such as a fast-forward operation, the operation image SD
The above processing method of prohibiting the erasing of the pointer P and the movement of the pointer between them becomes very suitable.

In this flow chart, the operation image SD and the pointer P are erased during the enter operation period, but since the enter operation is often a short-time operation, the enter information is input. A predetermined period from the time point is counted, and only during that time, the operation image SD
The display output of the pointer P may be stopped.

By the way, an operation image SD for the AV selector amplifier 10 is also prepared in order to switch the input function, and in the case of the present embodiment in order to call this operation image SD, the operation image SD for each device is displayed. At the time of display, an operation image that means a menu is also displayed (see FIG. 11). Then, for example, when the pointer P is moved from the state of FIG. 11A to be positioned on the operation image SD of the menu as shown in FIG. 12 and the enter operation is performed in this state, the process of the control unit 23 is step F207. To F218
Will proceed to.

Here, the control section 23 transmits the operation image data for the menu screen to the graphic controller 25. Then, as shown in FIG. 13, for example, an operation image SD (operation image for the AV selector amplifier 10 itself) for a menu screen showing input function switching and volume up / down operations is displayed on the screen.

In this display state, for example, the pointer P
Is moved to the volume-up operation image SD and an enter operation is performed, and since this is an operation of the AV selector amplifier 10 itself, the process proceeds from step F208 to F219, and then to F220 for volume control. Done.
That is, the control section sends a volume-up command to the volume control section 12.

On the other hand, for example, when the pointer is moved to the position of the operation image SD of "TV" to enter so as to switch the input function to the TV tuner 63, the process proceeds from step F219 to F221, and the control unit 23 To the audio input switching unit 11 and the video input switching unit 14,
The command will be sent so that the TV tuner is selected.

It should be noted that when operating the AV selector amplifier 10 itself as described above, the character image is not supplied from any other device, so that the operation image SD and the pointer P need not be erased, and they can be used as they are. The display continues.

When the input function is switched, the process returns to step F201, and the control section 23 sets the switching control signal Y _S to L level to eliminate the superimposing of the operation image SD and the pointer P. Then, in step F202, the operation image data for the TV tuner in this case is transmitted to the graphic controller 25 in accordance with the input function.

In this state, only the image of the television broadcast is output on the screen of the monitor device 70. If any operation information is input from the remote commander R at this time, the process proceeds from step F203 to F204, F205. , Superimposing of the operation image SD and the pointer P is executed. In this case, for example, as shown in FIG. 14, the TV tuner 6
Corresponding to No. 3, the operation image SD of the numeric keys for direct channel switching operation and the operation image SD of channel up / down are displayed.

After that, the processes of steps F209 to F213 are performed as in the case of the LDP 64 described above. For example, in FIG.
When the pointer P is entered at the channel-up position as in (a) (when the operation image deletion mode is on), the operation image SD and the pointer P are deleted on the screen during the enter operation. And the TV tuner 63
Then, a new channel number (for example, "6") is output as a character image according to the channel switching, but the display of "6" is not disturbed by the operation image SD as shown in FIG. 14 (b). Will be displayed in. Then, when the enter operation is completed (or when a predetermined time has elapsed from the enter operation), the operation image SD is again displayed.
And the pointer P is displayed, returning to the state of FIG.

As described above, in this embodiment, the operation image S
Since the D and the pointer P are erased from the screen during the enter operation (or a predetermined period from the enter operation),
Even when the operation of the device according to the operation is executed and the device outputs the character image according to the operation, the character image does not become difficult to see or disappear on the screen, and the user can see the device You can check the operating status.

In addition, an operation image SD is generated by an enter operation.
Also, by prohibiting the movement of the pointer P while the pointer P is being erased, the pointer P will not move carelessly, and the user will not be able to enter when the angular velocity remote commander is used, for example. X during operation
There is no need to be careful so that y displacement information is not output.

Incidentally, various transmission methods of the command code of the control unit 20 using the display of the operation image SD and the pointer P can be considered other than the processing of FIG. In particular, the operation image switching method and the like can be implemented in various ways in addition to the above-mentioned function menu screen.

Further, the operation image erasing mode is turned on / off by the user by the mode switching unit 28, but this may also be performed by an enter operation on the screen. Further, the system may be configured with the operation image erasing mode always on without providing the mode switching means.

Further, the control unit 20 is an AV
Although it is incorporated in the selector amplifier 10, it may be incorporated in another device or the control unit may be configured as a single unit.

Further, instead of being used for the AV system, such a control system may be used for a personal computer or the like. Then, when a so-called multi-window display is performed on the monitor screen of the personal computer to display the operation image, the image being entered is erased as in the above embodiment.

Although the remote commander is used as the operation input means, a touch panel provided on the housing of the control unit may be used as the operation input means. Of course, other than this, an operation input means other than the remote method can be adopted.

[0079]

As described above, in the control system of the present invention, the operation image and the position designation image are erased from the screen during the enter operation or for a predetermined period after the enter operation, so that the operation system responds to the operation. Even when the operation of the device is executed and the device outputs a character image according to the operation, the character image has the effect of not becoming difficult to see or disappear on the screen.
The user can confirm the operating condition well.

Further, by not accepting the command code for moving the position designation image during the period in which the operation image and the position designation image are erased by the enter operation, the position designation image is carelessly (not visible to the user). Has the advantage that it does not move and the operation is not confused. Furthermore, even if the angular velocity remote commander is used as the operation input means, the xy displacement information is not output during the enter operation by the user. There is also an effect that you do not have to be careful not to move the remote commander.
