Such a setting operation on the menu screen is performed by inputting a cursor key, a confirmation key, or the like provided on an operation unit such as a remote controller.

However, in such a menu screen, there are many cases where only setting items are arranged, and there is a problem that it is difficult to understand how to set each item. For such a problem, a television receiver that displays an operation guide is known (for example, see Patent Document 1).
The television receiver described in Patent Literature 1 displays a guide screen for explaining a setting operation by inputting a guide key such as a remote controller while a setting item is selected while a menu screen is displayed. Thereby, a necessary operation guide screen can be displayed by a simple operation, and the operation on the menu screen can be easily understood.

JP-A-8-65587

  However, in the television receiver described in Patent Document 1, although the operation guide is displayed, the setting operation on each menu screen can be easily understood, but which setting item should be set on which menu screen. There is a problem that it is difficult to understand. That is, the menu screen of the television receiver described in Patent Document 1 is an item-specific setting screen in which the menu screen is configured for each setting item such as video and audio. There was a problem that the user had to find out if it was on the screen, and the setting operation was troublesome.

  An object of the present invention is to provide an image display device capable of easily changing settings.

  In order to achieve the above-described object, an image display device of the present invention is an image display device including an image display unit that displays an image according to input image information, and a control unit that controls the entire device. An operation unit that has at least one key and causes the control unit to execute an operation corresponding to an input operation of the key, the control unit including the input operation in accordance with a predetermined operation state of the control unit An input determination unit that determines whether or not the input operation is valid, and a counter that counts the number of times the input operation determined to be invalid is performed when it is determined that the input operation is not valid. A number determination unit that determines whether or not the number of times has reached a predetermined number or more, and an interactive type that displays an interactive setting screen on the image display means when it is determined that the number of times has reached a predetermined number or more With the setting screen display Characterized in that it obtain.

Here, on the interactive setting screen, one item to be set is displayed in a question format, and by selecting from “YES” and “NO”, or by selecting from a plurality of options The menu screen which can set an item is shown.
The effective input operation refers to a key input operation that can be executed by the control means in a predetermined operation state according to the input operation. As such an effective input operation, for example, a screen transition in the menu screen, selection of a setting item, input, determination, and cancellation for a control means in a menu screen display state in which the operation setting of the image display device can be changed An input operation for executing a menu operation such as
On the other hand, an invalid input operation refers to a key input operation incapable of being executed by the control means in a predetermined state according to the input operation. For example, an input operation other than the input operation related to the menu operation described above can be given to the control means in the menu display state. In addition, when the image display device is a television receiver capable of receiving analog broadcasting, digital broadcasting, and data broadcasting, an input operation for displaying an image of data broadcasting during the display of a television program based on the analog broadcasting can be given.

According to the present invention, the interactive setting screen is displayed on the image display means when an input operation that is not valid for the control means in a predetermined operation state is performed on the keys of the operation means more than a predetermined number of times. Therefore, the setting operation can be easily performed.
That is, when an input operation is performed on a key of the operation unit, the input determination unit of the control unit determines whether the input operation on the key is an effective input operation for the control unit in a predetermined operation state. Is done. When the signal determination unit determines that the input operation is not a valid input operation, the number of such invalid input operations is counted by the counting unit. Here, the number of invalid input operations is monitored by the number determination unit, and the number determination unit determines whether or not the number of times has reached a predetermined number. When the number determining unit determines that the number of invalid input operations has reached a predetermined number or more, the interactive setting screen display unit displays an interactive setting screen on the image display means.

  According to this, an input operation to the operation unit that is not allowed depending on the operation state of the control unit that controls the image display device is detected, the number of the input operation is counted as the number of invalid input operations, To display the interactive setting screen. That is, when the user attempts to change the setting state of the image display device, the user performs an input operation on the key of the operation unit not involved in the operation state of the current control unit, and the number of the input operation reaches a predetermined number or more In addition, it is possible to display an interactive setting screen that can easily change the settings of the image display device. Therefore, the setting item that the user wants to set can be easily found, and the setting operation can be easily performed on the interactive setting screen.

  In the present invention, when the input determination unit determines that the input operation is not a valid input operation, the control unit performs a period from when the invalid input operation is performed until another valid input operation is performed. A first time measuring unit for measuring time, and a first time measuring time determining unit for determining whether or not a time measured by the first time measuring unit has reached a predetermined time, the interactive setting screen display unit, When the first time measuring unit determines that the time measured by the first time measuring unit has reached a predetermined time, and the number determining unit determines that the number of times has reached a predetermined number or more, the interactive setting screen Is preferably displayed.

According to the present invention, an invalid input operation is continuously performed within a predetermined time, and the interactive setting screen is displayed when the number of the invalid input operations reaches a predetermined number or more. Therefore, it is possible to prevent the interactive setting screen from being displayed unnecessarily frequently.
That is, when the signal determination unit determines that the input operation on the key of the operation unit is not an effective input operation for the control unit in a predetermined operation state, the input operation determined to be invalid is performed. The time from the time until another effective input operation is performed is counted by the first timer. Here, until a valid input operation is performed, even when an invalid input operation is performed, the timing by the first timing unit is continued. On the other hand, the first timekeeping time determination unit determines whether or not the time measured by the first timekeeping unit has reached a predetermined time. The interactive setting screen display unit displays the interactive setting screen on the image display means when the time counted by the first time measuring unit reaches a predetermined time and the number of invalid input operations reaches the predetermined number. .

  According to this, during the period from when a key input operation that is not valid for the control means in a predetermined operation state to when another valid input operation is performed, the number of key input operations that are not valid is the predetermined number of times. When reaching the above, the interactive setting screen display unit can display the interactive setting screen. Accordingly, by appropriately setting the predetermined time and the predetermined number of times described above, it is possible to prevent the interactive setting screen from being frequently displayed unnecessarily and to prevent the original image display from being hindered. .

According to the present invention, it is determined at the time of setting of the signal determination unit whether or not the input operation with respect to the key of the operation unit that causes the control unit to execute a predetermined operation while the item-specific setting screen is displayed is an effective input operation. It can be determined appropriately by the part.
That is, on the item-specific setting screen, screen transition operations, setting item selection operations, confirmation operations, cancellation operations, and the like are often performed, and input operations performed on the operation means compared to normal image display. It is complicated to determine whether or not the control means can execute an operation according to the above, that is, whether or not the input operation is an effective input operation. Here, in the present invention, the determination process is appropriately performed by providing the signal determination unit with the setting time determination unit that determines whether or not the input operation to the key of the operation unit during display of the item setting screen is valid. Can be done. Therefore, it is possible to appropriately perform the determination process when changing the display from the item-specific setting screen to the interactive setting screen.

A second time measuring time determining unit that determines whether or not the time measured by the unit has reached a predetermined time or more, and the interactive setting screen display unit is configured such that the second time measuring unit determines the second time measuring unit. When it is determined that the timed time has reached a predetermined time or more, the interactive setting screen is preferably displayed.

According to the present invention, the second time measuring unit measures the time from when the input operation to the key of the operation means is performed while the item-specific setting screen is displayed until another input operation is performed, Is determined by the second timing determination unit. When the second time measuring unit determines that the time measured by the second time measuring unit has reached a predetermined time, the interactive setting screen display unit displays the interactive setting screen on the image display unit. Is displayed.
According to this, when the input operation with respect to the key of the operation means is not performed within a predetermined time during the display of the item-specific setting screen, the interactive setting screen can be displayed. Accordingly, the interactive setting screen can be automatically displayed when the user is confused by the setting operation on the item-specific setting screen or when the user is at a loss of the setting. Setting operation can be performed.

  In the present invention, the operation means includes an operation signal output unit that outputs an operation signal corresponding to the key on which the input operation has been performed, and the input determination unit performs an operation based on a type of the operation signal. It is preferable to determine whether or not the input operation is an effective input operation by determining whether or not the operation is in accordance with a predetermined operation state of the control means.

Here, the operation means may be connected to the control means by wire or may be connected wirelessly.
According to the present invention, the input determination unit determines whether or not the input operation is a valid input operation based on the type of the operation signal output according to the key on which the input operation has been performed. The operation on the control means specified by the operation signal can be properly grasped. Accordingly, it is possible to appropriately determine whether or not the key input operation of the operation unit is an effective input operation based on whether or not the operation can be performed on the control unit. Therefore, it is possible to appropriately determine the validity of the key input operation by the input determination unit.

More specifically, FIG. 3 is a diagram of an interactive setting screen showing the setting items of “automatic setup” shown in FIG. 2 in question format, and FIG. 4 is a setting item of “aspect ratio”. It is the figure of the interactive type setting screen which represented in question form.
Here, the interactive setting screen will be described.
The interactive setting screen is a menu screen where one item to be set is displayed in a question format, and items can be set by selecting from "Yes" and "No" or by selecting from multiple options. It is shown. Specifically, in the interactive setting screen of the present embodiment, the “video”, “audio”, “setting”, “information”, and “initialization” menus are provided as in the above-described item-specific setting screen.

The memory 54 stores, as data, menu data referred to when each setting screen is generated by the item-specific setting screen generation unit 531 and the interactive setting screen generation unit 532 described above. Further, the memory 54 stores a counter referred to in an operation signal handling process SA described later.

(4) Configuration of Control Circuit 55 FIG. 5 is a block diagram of the control board 5 mainly showing the configuration of the control circuit 55.
The control circuit 55 includes a CPU (Central Processing Unit) and the like, and reads a program stored in the memory 54 to autonomously control the control board 5 and thus the receiver main body 2 as well as the remote control IF 3 and the operation. The control board 5 is controlled based on an operation signal input from the panel 4 to control the driving of the entire receiver body 2.
Therefore, as shown in FIG. 5, the control circuit 55 includes a signal determination unit 551, a counting unit 552, a frequency determination unit 553, a timer unit 554, and a signal processing unit 555.

The signal determination unit 551 corresponds to the input determination unit of the present invention, and the input operation signal will be described later based on the operation signal input from the remote control 9 via the remote control IF 3 and the operation signal input from the operation panel 4. By determining whether or not the signal processing unit 555 is an operation signal for instructing an operation that can be performed, the input operation to the keys of the remote controller 9 and the operation panel 4 that output the operation signal is an effective input operation. It is determined whether or not. The determination criterion in the determination process performed in the signal determination unit 551 is changed depending on the state of the receiver body 2, that is, the operation state of the control board 5.
Such a signal determination unit 551 includes a state acquisition unit 5511, a determination control unit 5512, a setting display time determination unit 5513, and a normal display time determination unit 5514.

The state acquisition unit 5511 acquires the operation state of the control board 5, for example, whether or not the control board 5 is displaying the item-specific setting screen, and indicates the determination result to the determination control unit 5512. Output a control signal.
Based on the control signal from state acquisition unit 5511, determination control unit 5512 determines whether or not processing based on operation signals input from remote control IF 3 and operation panel 4 can be executed by signal processing unit 555 described later. Sort processing.
Specifically, if the setting screen for each item is being displayed, the determination control unit 5512 causes the setting display time determination unit 5513 to execute the determination process for the input operation signal, and displays the setting screen including the interactive setting screen. If not, the normal display time determination unit 5514 executes the determination process. Further, the determination control unit 5512 outputs a control signal including the signal type of the input operation signal to the signal processing unit 555.

The setting display time determination unit 5513 corresponds to the setting time determination unit of the present invention. Based on the control signal input from the determination control unit 5512 and including the type of the operation signal, the signal determination unit It is determined whether or not the operation signal input to 551 can be executed by the signal processing unit 555 displaying the setting screen for each item.
For example, the operation signal for executing the process of selecting the menu item, the operation signal for inputting the value of the setting item, and the operation signal for determining and canceling the setting item on the item-specific setting screen are valid inputs. It is determined that the operation signal is based on the operation. On the other hand, during the display of the item-specific setting screen, the operation signal for switching the input image information is determined to be an operation signal based on an invalid input operation.

In such a determination, when it is determined that the operation based on the input operation signal can be executed by the signal processing unit 555, the setting display time determination unit 5513 assumes that an operation signal based on an effective input operation has been input. , A control signal indicating that an operation signal based on an effective input operation is input to the counting unit 552, the first timing unit 5541 and the second timing unit 5544 of the timing unit 554, and the normal processing instruction unit 5553 of the signal processing unit 555. Is output.
On the other hand, if it is determined that the operation based on the input operation signal is not executable by the signal processing unit 555, the setting display time determination unit 5513 determines that the operation signal based on an invalid input operation has been input, In addition, a control signal indicating that an operation signal based on an invalid input operation has been input is output to the condition determination unit 5551 of the signal processing unit 555. In addition, when the determination result at the previous setting display time determination unit 5513 has determined that an operation signal based on an effective input operation has been input, the first timer unit 5541 and the second timer unit of the timer unit 554 The same control signal is output to 5544.

Based on a control signal that is input from the determination control unit 5512 and includes the type of operation signal, the normal display time determination unit 5514 is not displaying the item-specific setting screen and the interactive setting screen, that is, an image display such as a TV program. It is determined whether or not an operation based on the operation signal input to the signal determination unit 551 can be executed by the signal processing unit 555.
For example, since the operation signal for adjusting the volume is an operation signal for an operation that can be processed by the signal processing unit 555, the operation signal is an operation signal based on an effective input operation by the normal display time determination unit 5514. Determined. The operation signal for displaying the data broadcast image during the display of the image based on the analog broadcast does not include the data for displaying the data screen in the analog broadcast. I can't do it. For this reason, the normal display time determination unit 5514 determines that the operation signal is an operation signal that is not operable by the signal processing unit 555, that is, an operation signal based on an input operation that is not valid.

In such determination, when the normal display time determination unit 5514 determines that the operation signal input to the signal determination unit 551 is an operation signal based on a valid input operation, the normal display time determination unit 5514 A control signal indicating that an operation signal based on an effective input operation has been input is output to unit 552, first timing unit 5541 of timing unit 554, and normal processing instruction unit 5553 of signal processing unit 555.
On the other hand, when the normal display time determination unit 5514 determines that the input operation signal is an operation signal based on an input operation that is not valid, the normal display time determination unit 5514 includes the counting unit 552 and the signal processing unit 555. A control signal indicating that an operation signal based on an invalid input operation is input to the condition determination unit 5551. Similarly, when the determination result in the normal display time determination unit 5514 immediately before has determined that an operation signal based on an effective input operation has been input, the same applies to the first time measuring unit 5541 of the time measuring unit 554. The control signal is output.

The counting unit 552 sets the value of the counter stored in the memory 54 each time a control signal is input from the setting display time determination unit 5513 and the normal display time determination unit 5514.
Specifically, the counter 552 sets the counter value stored in the memory 54 to the initial value “0” when a control signal indicating that an operation signal based on the above-described valid input operation has been input is input. To do. In addition, when a control signal indicating that an operation signal based on an invalid input operation is input, the counting unit 552 increments the value of the counter by “1”.

  The number determination unit 553 monitors the value of the counter stored in the memory 54 and determines whether or not the value of the counter has reached a predetermined value (a predetermined number of times). When the counter value reaches a predetermined value, the number determination unit 553 outputs a control signal indicating that the counter value has reached the predetermined value to a condition determination unit 5551 described later of the signal processing unit 555. To do. The predetermined value is about “5” in the present embodiment, but may be set as appropriate.

  Each time the control signal is input from the setting display time determination unit 5513 and the normal display time determination unit 5514, the time measuring unit 554 resets the timer and measures the time from when the control signal is input. The timer unit 554 includes a first timer unit 5541, a first timer 5542, a first timer unit 5543, a second timer unit 5544, a second timer 5545, and a second timer unit 5546.

When the control signal indicating that the operation signal based on the above-described effective input operation is input from the setting display time determination unit 5513 and the normal display time determination unit 5514, the first time measurement unit 5541 and the second time measurement unit 5544 receive The first timer 5542 and the second timer 5545 are reset.
First time determination unit 5543 and second time determination unit 5546 monitor the times of first timer 5542 and second timer 5545, respectively, and determine whether or not a predetermined time has elapsed. When the time of the first timer 5542 reaches a predetermined time or more, the first time measurement determination unit 5543 sends the elapsed time of the first timer 5542 to the condition determination unit 5551 described later of the signal processing unit 555. A control signal indicating that the time has been reached is output. When the time of the second timer 5545 has reached a predetermined time or more, the second time measurement determination unit 5546 sends a control signal indicating that the elapsed time of the second timer 5545 has reached the predetermined time or more to the condition determination unit. To 5551.

  The signal processing unit 555 executes processing according to the operation signal input to the control circuit 55 and instructs display of the interactive setting screen according to the above-described counter and time keeping time. Therefore, the signal processing unit 555 includes a condition determination unit 5551, an interactive screen generation instruction unit 5552, a normal processing instruction unit 5553, and an item-specific screen generation instruction unit 5554.

  The condition determination unit 5551 determines a condition for displaying the interactive setting screen. Specifically, the condition determination unit 5551 is configured to perform a count determination unit when a control signal indicating that an operation signal based on an invalid input operation is input from the setting display determination unit 5513 and the normal display determination unit 5514. 553, based on control signals from the first time measurement determination unit 5543 and the second time measurement determination unit 5546, it is determined whether or not to output a control signal to the interactive screen generation instruction unit 5552.

  More specifically, the condition determination unit 5551 receives a control signal indicating that an operation signal based on the above-described effective input operation is input from either the setting display time determination unit 5513 or the normal display time determination unit 5514. It is determined whether or not a control signal indicating that the elapsed time of the first timer 5542 has reached a predetermined time or more is input from the 1 time measuring time determination unit 5543. If it is determined that the control signal is input, the condition determination unit 5551 determines whether the control signal indicating that the counter stored in the memory 54 has reached a predetermined number of times or more is input from the number determination unit 553. Determine. If it is determined that the control signal is input, the condition determination unit 5551 outputs a control signal to the interactive screen generation instruction unit 5552. In this case, the condition determination unit 5551 outputs control signals to the counting unit 552, the first timing unit 5541 and the second timing unit 5544 of the timing unit 554, and resets the counter, the first timer 5542, and the second timer 5545. Is executed.

  When the control signal indicating that the item-specific setting screen is being displayed is input from the setting display time determination unit 5513 to the condition determination unit 5551, the elapsed time of the second timer 5545 from the second time determination unit 5546 is predetermined. It is determined whether or not a control signal indicating that time has elapsed is input. If it is determined that the control signal is input, the condition determination unit 5551 outputs a control signal to the interactive screen generation instruction unit 5552. In this case as well, the condition determination unit 5551 outputs control signals to the counting unit 552, the first timing unit 5541 and the second timing unit 5544 of the timing unit 554, and the counter, the first timer 5542, and the second timer 5545 reset is executed.

  The interactive screen generation instruction unit 5552 constitutes the interactive setting screen display unit of the present invention. Then, when the control signal is input from the condition determination unit 5551, the interactive screen generation instruction unit 5552 generates image information of the interactive setting screen in the interactive setting screen generation unit 532 of the setting screen generation unit 53, and the image sound A control signal to be output to the processing circuit 52 is generated and output.

  When a control signal including an operation signal type is input from the determination control unit 5512, the setting display time determination unit 5513, and the normal display time determination unit 5514, the normal processing instruction unit 5553 performs processing corresponding to the operation signal type on the control board 5. Have each functional unit execute. Note that operation signals that cannot be processed by the normal processing instruction unit 5553 are not input from the signal determination unit 551 to the normal processing instruction unit 5553.

Specifically, when an operation signal indicating volume adjustment or channel change is input, the normal processing instruction unit 5553 outputs a control signal to the image / audio processing circuit 52 and the tuner 51 to execute the processing. In addition, when an operation signal for changing the position of the cursor or the like is input while the item-specific setting screen and the interactive setting screen are displayed, the normal processing instruction unit 5553 outputs a control signal to the setting screen generation unit 53. Then, a screen reflecting the operation is generated. Furthermore, the normal process instruction unit 5553 outputs a control signal to the item-specific screen generation instruction unit 5554 when an operation signal for displaying the item-specific setting screen is input.
Note that the normal processing instruction unit 5553 performs processing according to the operation signal included in the input control signal, and then outputs a control signal to the counting unit 552, the first time measuring unit 5541, and the second time measuring unit 5544, and the counter The first timer 5542 and the second timer 5545 are reset.

The data is output to the separate setting screen generation unit 531.

(5) Operation signal handling process SA
FIG. 6 is a diagram showing a processing flow of the operation signal correspondence processing SA.
When an operation signal is input from the remote control IF 3 or the operation panel 4, the control circuit 55 executes the following operation signal corresponding processing SA by the function units 551 to 555 constituting the control circuit 55. The operation signal handling process SA processes the input operation signal and determines whether or not the operation signal is an operation signal that can be executed by the signal processing unit 555 of the control board 5 in a predetermined state. It is determined whether or not the operation signal is based on an input operation, and when the operation signal that is not executable, that is, the operation signal based on the input operation that is not valid is continuously input within a predetermined time for a predetermined number of times or more, the above-described dialogue This is a process for displaying a type setting screen. Such processing SA is performed by executing the operation signal corresponding program stored in the memory 54.
Hereinafter, the operation signal handling process SA will be described with reference to FIG.

  In the operation signal handling process SA, as shown in FIG. 6, it is first determined whether or not the operation signal input to the control circuit 55 is an operation signal based on an invalid key input operation (process SA01). That is, in the process SA01, it is determined whether or not the operation according to the operation signal input to the control circuit 55 can be executed by the signal processing unit 555 of the control board 5 in a predetermined state. At this time, the state acquisition unit 5511 of the signal determination unit 551 determines whether or not the item-specific setting screen is being displayed. If the display is being performed, the determination process SA01 is processed by the setting display time determination unit 5513 under the control of the determination control unit 5512. If the display is not being performed, the process SA01 is performed by the normal display time determination unit 5514. It is processed.

In the determination process SA01, the setting display time determination unit 5513 or the normal display time determination unit 5514 is an input operation in which an input operation performed on the keys of the remote controller 9 or the operation panel 4 is valid, that is, by the input operation. When it is determined that the signal processing unit 555 can execute an operation according to the operation signal input to the control circuit 55, the processing according to the operation signal is performed by the normal processing instruction unit 5553 or the item-specific screen of the signal processing unit 555. Processing is performed by the generation instruction unit 5554 (processing SA02).
For example, when an operation signal for displaying an item-specific setting screen is input, the item-specific setting screen can be displayed regardless of the state of the signal processing unit 555. An item-specific setting screen generation signal is output to the item-specific setting screen generation unit 531 of the generation unit 53 to generate image information of the screen. When an operation signal for volume adjustment or the like is input, the normal processing instruction unit 5553 outputs a control signal to the image / sound processing circuit 52 and the like, and processing according to the operation signal is executed. Further, when a channel change operation signal is input when the item-specific setting screen or the interactive setting screen is not displayed, a control signal is output from the normal processing instruction unit 5553 to the tuner, and the channel indicated by the control signal is displayed. Changes to are performed.
After the process SA02, the control circuit 55 proceeds to process SA07.

  On the other hand, in process SA01, the input operation performed on the keys of the remote controller 9 or the operation panel 4 by the setting display time determination unit 5513 or the normal display time determination unit 5514 is an invalid input operation. When the signal processing unit 555 determines that the operation according to the operation signal input to the control circuit 55 is not executable by the counting unit 552 of the control circuit 55, the counter value stored in the memory 54 is “1”. It is advanced (processing SA03). The counter value is monitored by the number determination unit 553 and compared with a predetermined number of times, and then the determination result is output to the condition determination unit 5551 of the signal processing unit 555.

After the process SA03, the display condition of the interactive setting screen is determined. At this time, first, the first time measuring time determination unit 5543 determines whether or not the elapsed time of the first timer 5542 has reached a predetermined time or more (processing SA04).
Here, if the first time measuring time determination unit 5543 determines that the elapsed time of the first timer 5542 has not reached the predetermined time or more, the current state is maintained and the next operation signal is input. However, the operation signal handling process SA ends.
On the other hand, when it is determined that the elapsed time of the first timer 5542 has reached a predetermined time or more, a control signal is output from the first time measurement determination unit 5543 to the condition determination unit 5551 of the signal processing unit 555.

Next, the number determination unit 553 determines whether or not the counter value stored in the memory 54 has reached a predetermined value (predetermined number of times) or more (processing SA05).
Here, when the number determination unit 553 determines that the value of the counter has not reached the predetermined value, the number determination unit 553 does not output a control signal to the condition determination unit 5551. Thereafter, the control circuit 55 proceeds to process SA08.
On the other hand, when the number determination unit 553 determines that the value of the counter has reached a predetermined value or more, the number determination unit 553 outputs a control signal to the condition determination unit 5551.

  In process SA04 and process SA05, condition determination unit 5551 to which the control signal is input from first time measurement unit 5543 and frequency determination unit 553 outputs a control signal to interactive screen generation instruction unit 5552, and the interactive screen The generation instruction unit 5552 instructs the display of the interactive setting screen. Thereby, the interactive setting screen generating unit 532 of the setting screen generating unit 53 generates image information of the interactive setting screen, and the above-described interactive setting screen is displayed on the image display unit 6 (processing SA06).

After the process SA06, the condition determination unit 5551 outputs a control signal to the counting unit 552, and resets the counter value stored in the memory 54 to the initial value “0” (process SA07).
In addition, since the elapsed time of the first timer 5542 has reached the predetermined time or more, the condition determination unit 5551 outputs a control signal to the first timer unit 5541 to reset the first timer 5542 (processing SA08). With the end of the process SA08, the control circuit 55 ends the operation signal handling process SA.
When the process SA02 is shifted to the process SA07, the control signal to the counting unit 552 in the process SA07 and the control signal to the first timer unit 5541 in the process SA08 are output from the normal process instruction unit 5553. .

  With the operation signal handling process SA as described above, when an operation signal based on an input operation that is not valid within a predetermined time is continuously input a predetermined number of times or more, it is considered that the user is lost in setting operation or execution operation. You can hesitate to display the interactive setting screen. Accordingly, the setting operation of the receiver body 2 can be performed more easily.

(6) Setting screen display monitoring process SB
FIG. 7 is a diagram showing a processing flow of the setting screen display time monitoring process SB.
The setting screen display time monitoring process SB is interactive when the operation is not performed for a predetermined time or longer, that is, when an operation signal is not input to the control circuit 55 for a predetermined time or longer during the display of the item-specific setting screen. This is a process for displaying a setting screen.
Hereinafter, the setting screen display monitoring process SB will be described with reference to FIG.

In the setting screen display monitoring process SB, as shown in FIG. 7, first, an operation signal for executing menu display is output from the remote control IF 3 or the operation panel 4 (process SX01), and the operation signal is input to the control circuit 55. After the determination control unit 5512 that constitutes the signal determination unit 551 of the control circuit 55 causes the normal display time determination unit 5514 to execute the determination process, the normal display time determination unit 5514 instructs the signal processing unit 555 to perform normal processing. A control signal is output to unit 5553. Then, the normal processing instruction unit 5553 generates and displays the item-specific setting screen by the item-specific setting screen generation unit 531 of the setting screen generation unit 53 via the item-specific screen generation instruction unit 5554 (processing SB01).
Further, in the process SB01, a control signal is output from the normal display time determination unit 5514 to the second clock unit 5544, the second timer unit 5544 resets the second timer 5545, and a new clock is started.

  After the process SB01, the signal determination unit 551 of the control circuit 55 determines whether or not the next operation signal is input (process SB02). When the next operation signal is output (processing SX02) and the operation signal is input to the control circuit 55, the setting display determination unit 5513 of the control circuit 55 sets the setting for each item in which the input operation signal is being displayed. It is determined whether or not the operation signal is for executing a menu operation on the screen (processing SB03).

Here, when it is determined that the operation signal is a menu operation, the setting display time determination unit 5513 outputs a control signal including the type of the operation signal to the normal processing instruction unit 5553 of the signal processing unit 555, and The normal process instruction unit 5553 causes a menu operation corresponding to the operation signal to be executed (process SB04). Further, the setting display time determination unit 5513 outputs a control signal to the counting unit 552 and the first time measuring unit 5541, and causes the counting unit 552 to reset the counter stored in the memory 54 (processing SB05). The timer unit 5541 resets the first timer 55412 (process SB06). Thereafter, the control circuit 55 proceeds to process SB07.
On the other hand, when it is determined that the operation signal is not an operation signal for executing the menu operation, the setting display time determination unit 5513 executes the operation signal handling process SA described above (process SA).

After the operation signal handling process SA in the setting screen display time monitoring process SB or after the process SB06, the signal processing unit 555 of the control circuit 55 outputs a control signal to the second timer unit 5544, and the second timer 5545. Is reset (process SB07).
Thereafter, based on the information input from the state acquisition unit 5511, the determination control unit 5512 determines whether or not the interactive setting screen is displayed by the operation signal corresponding processing SA (processing SB08). If it is determined in the determination process SB08 that the interactive setting screen is not displayed, the control circuit 55 returns to the process SB02. When it is determined that the interactive setting screen is displayed, the control circuit 55 ends the setting screen display time monitoring process SB.

On the other hand, if it is determined in step SB02 that there is no operation signal input, the second timer 5545 continues to monitor the elapsed time of the second timer 5545, and the second timer 5545 has elapsed. Time is determined (processing SB09).
Here, when the second measured time determination unit 5546 determines that the elapsed time of the second timer 5545 is less than the predetermined time, the control circuit 55 returns to the process SB02.

In addition, when the second clock time determination unit 5546 determines that the elapsed time of the second timer 5545 has reached a predetermined time or more, the second clock time determination unit 5546 sends the condition determination unit 5551 of the signal processing unit 555 to the condition determination unit 5551. Output a control signal. Then, the condition determination unit 5551 to which the control signal is input causes the interactive screen generation instruction unit 5552 to display an interactive setting screen (processing SB10). Thereafter, the condition determination unit 5551 outputs a control signal to the counting unit 552, the first timer unit 5541, and the second timer unit 5544, and resets the counter, the first timer 5542, and the second timer 5545 (processing SB11). ~ SB13).
After the process SB13, the control circuit 55 ends the setting screen display time monitoring process SB.

  When the operation signal is not input within a predetermined time during the display of the setting screen for each item by the monitoring process SB during the setting screen display as described above, it is assumed that the user is confused about the setting operation, An interactive setting screen can be displayed. Therefore, the setting operation of the receiver body 2 can be performed more easily.

With the television receiver 1 as described above, the following effects can be obtained.
That is, when the number of invalid key input operations, that is, the number of input operation signals that cannot be executed by the signal processing unit 555 constituting the control circuit 55 of the control board 5 reaches a predetermined number, Will display the interactive setting screen. This makes it possible to display the interactive setting screen when the user is confused about the setting or operation, or the operation method is unknown. Therefore, operations such as setting of the receiver body 2 can be easily performed.
