Description

TECHNICAL FIELD The present invention relates to an image information display device, and particularly relates to image information outputted from the selected device by selecting one of a plurality of information output devices, and the device. The present invention relates to a display device that displays at least one type of information.

Fungi technology Conventionally, this type of device has multiple information output devices such as audio devices and navigation devices as sources, selects these sources as appropriate, and outputs image information output from that source, information related to the source, etc. An image display means that is displayed on the screen is known. Note that the navigation device is used by being mounted on a motor vehicle, and provides route map information and the like to the passengers of the vehicle in order to make driving the vehicle easier.

In such an image information display device, for example, when a navigation device is selected and passage map information is displayed on the screen, when another source, for example an audio device, is selected, information related to that device, such as a CD, is displayed. (
In the CD player, function key information indicating the function of the track CD recorded on the CD is displayed on the screen instead of the passage map information.

This kind of information is no longer needed once you have looked through it manually, and on the other hand, route map information is always needed as long as you continue to drive. Therefore, after the operation regarding the audio device is completed, it is necessary to display the passage map information on the screen again.

In conventional devices, when displaying the passage map information on the screen again, it was configured to be achieved by manually operating the keys, so one manual operation of the keys was always required, and that operation was cumbersome. Considering the case where the driver is operated while driving, it is preferable from the point of view of safety that the number of operations is reduced by at least one.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points, and provides an image information display device with improved operability by automatically recalling the original screen without any operation. The purpose is to

An image information display device according to the present invention includes a plurality of information output devices, a selection switch for selecting any one of the plurality of information output devices, and image information output from the information output device selected by the selection switch. and an image display means for displaying at least one of information related to the selected information output device, and a controller for controlling display information displayed on both sides of the image display means, , if another information output device is selected while displaying the image information output from the information output device, the function key information of this other information output device is displayed for a predetermined time G'J
After the display is avoided, control is performed to display predetermined image information.

Example Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention,
Four sources, a TV corner, an AM/FM tuner, a CD player, and a navigation system (NAVI) device, are used as information output devices, and four controllers 11 to 14 are provided corresponding to each of these sources.

Furthermore, there are display controllers 1 to 4 that control the image information displayed on the screen of the CRT display 3, and a key input circuit to which the detection output of the touch sensor 5 installed on the screen of the CRT display 3 is supplied. 6, which are connected to the system controller 7 via a path line 8, through which display information, control information, key human input information, etc. are transmitted. Note that as the touch sensor 5, a transparent electrode, an infrared sensor, or the like may be used.

Further, a selection switch device 9 for selecting one of the plurality of sources is provided, and this selection switch device 9
For example, it has an external switch configuration, and as shown in FIG. 2, there are four selection switches 11 to 11 corresponding to each source.
14, arranged around the screen of the CRT display 3, for example. The system controller 7 controls each controller 11 to 14 on/off in accordance with the source selection information from the selection switch device 9.

Next, regarding the operation of the image information display device according to the present invention,
For example, the selection of a navigation device will be explained along the flowchart of FIG. 3.

First, when a navigation device is selected by turning on the selection switch 24, the NAV I mode is set in step 1, and the NAV I operation is performed (step 2). In this NAVI mode, route map information and the like are displayed on the screen of the CRT display 3 to inform the driver of the current position and the like relative to the destination. That is, in the NAV 1 mode, at least the b3a road map information (J1) is always displayed on the screen.

In this state, if there is a source selection input using keys other than those related to NAVI or input using the IR switches 21 to 23, this is determined in step 3. At this time, if it has been specified in advance that the information sent from the selected source will be automatically deleted after a certain period of time, this will be specified in step 4.
0 is judged, but the NA immediately before another source is selected
The display information related to the VI is stored, for example, in a storage section in the display unit 1 to the roller 4 (step 5).

For example, if the key manually operated by the selection switches 21 to 23 is Cr1
If it is determined that the selection switch 23 is selected (step 6), then the CD mode is set (step 7), and the display 1-roller 4 displays the information related to the CD from the CD controller 3. Information will be sent to you. Subsequently, it is determined whether new display information has been received (step 8);
If received, a timer in the roller 4 is set to the predetermined time (step 9). Then, new information is displayed on the screen (step 10), and the displayed information is as shown in FIG. 2, for example. After that, when it is determined that the specified period of time has elapsed (step 11),
Step 12) calls up the information that was previously stored in the storage section of the display controller 1 to roller 4 and was displayed until just before the source was switched, and displays that information on the screen again (step 13) .

On the other hand, if you have selected another source and have not specified that the information sent from the selected source should be automatically deleted after a certain period of time, this will be confirmed in step 4. When judged, display controller 1~
After completing steps 15 and 16, roller 4 continues to display new information regardless of the timer operation (step 17). In addition, in the above operation, the case where another source is selected has been explained, but it also applies when the function key information related to that mode is input via Touchron 1 No 5 in NAV mode and the screen is switched. , it is possible to perform an operation without automatically recalling the original information after a certain period of time has elapsed.

In the above embodiment, the timer function was explained as being provided in the display controller 1 and the roller 4, but the timer function is provided in the display controller 1 to the system controller 4.
The roller 7 may have a timer function and control the entire system, or each source may have a timer function and send out display information each time.

Furthermore, in the above embodiment, the case where the screen returns to the information display before switching was explained, but instead of returning to the information before switching, it is possible to display certain specified information after a certain period of time has elapsed. It is also possible to do so.

Furthermore, in the above embodiments, a TV chip, an AM/FM tuner, a CD player, and a NAVI device are used as sources, but the source is not limited to these, and may be, for example, a cassette deck, a video deck, or a gear shift system. It is also possible to use audio equipment, video equipment, information equipment, etc. In addition, when a navigation device is used as in the above embodiment, the image information display device according to the present invention is mounted on a vehicle, and in that case, the display section is mounted on the instrument panel in front of the driver. It is preferable that the 9T be placed within or near the 9T.

As described in detail of the invention, according to the image information display device of the present invention, even if another source is selected while displaying image information of one source and that information is displayed, the original image can be displayed without any operation. Since the screen can be recalled automatically, operability can be improved, and especially when considering in-vehicle devices, the number of operations to be performed while driving can be reduced, without compromising driving safety.
