Description

This invention relates to a multi-monitor system to manually control the plurality of monitors, a technique which particularly reflect the setting by another monitor to self monitor.

  Conventionally, a multi-monitor system is known in which one monitor shares one resource. For example, with the recent spread of car navigation devices, it is not uncommon for two or more car navigation devices each having a monitor to be present in the vehicle. In such a case, performing similar operations separately on each car navigation device and acquiring similar information wastes time and communication costs. In view of this, a system in which a plurality of car navigation devices or a part of them operate in cooperation has been considered.

  For example, Patent Document 1 discloses a vehicle navigation apparatus in which a second monitor is provided in a rear seat or the like in addition to a first monitor provided in a driver's seat. In this vehicle navigation device, the first signal input / output system for connecting the first monitor provided in the vicinity of the driver's seat to the video output device such as the navigation device and the television receiver is not only the first device selection switch but also when the vehicle is running. A function stop switch that is turned off is provided so that video equipment such as a television is not output when the vehicle is traveling, and the operation prohibition function during traveling in the navigation device cannot be operated, and only the specific function that can be operated during traveling can be operated. On the other hand, the second signal input / output system of the second monitor provided in the rear seat does not have the function stop switch as described above, and does not affect the first monitor, such as television reception and destination setting. Can perform the functions. This configuration eliminates the inconvenience that you cannot set the destination along the menu screen while the vehicle is running, and you cannot watch the TV on the second monitor unless the first monitor is turned off. is doing.

In addition, as a system having a plurality of monitors , a plurality of displays for the driver and passengers can be mounted, and each display can share one image. There is also known a vehicle information display method and apparatus capable of restricting display information only for use (see, for example, Patent Document 2). In the technique disclosed in Patent Document 2, when the same display information obtained from the information source is displayed on the display devices provided in the driver's seat and the rear seat, the video signal of the base image generated from the display information is displayed as video. The distribution circuit divides the signal into two and outputs one of them to the rear seat display device to display all information on the rear seat display device. While the vehicle is traveling, the mask image is stored in the VRAM to generate a video signal in which the base image and the mask image are synthesized by the video synthesizing circuit, which is output to the front seat display device and a part of the information is output. Display. While the vehicle is stopped, the mask image is erased from the VRAM to display all information on the front seat display device. As a result, it is possible to improve the safety by restricting the display information of the front seat display device while the vehicle is traveling.

  However, in the technique disclosed in Patent Document 1, the operation content on the second monitor in the rear seat is directly reflected on the first monitor in the front seat. In many cars, there are many children riding in the back seat, and parents in the front seat cannot know what is being operated in the back seat. Therefore, if the destination and waypoints are set on the second monitor in the rear seat and reflected directly on the first monitor in the front seat, the route displayed on the first monitor in the front seat changes, which hinders driving. There is a risk of causing. Even if an adult rides on the rear seat, it is possible that the above-described state may occur due to an erroneous operation.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a multi-monitor system that can control whether a setting using another monitor is applied to the own monitor.

The multi-monitor system according to the present invention includes a first monitor used for processing, a second monitor capable of setting processing conditions for processing using the first monitor, and processing conditions set by the second monitor for the first monitor. a designation means for designating whether to automatically reflect processing performed using, if specified that does not automatically reflected by the specification means, the set processing conditions in the second monitor Inquiries to the operator of the first monitor by outputting a message or the like as to whether or not to reflect in processing performed using the first monitor , and instructed to reflect in response to the inquiry, processing conditions are And control means for reflecting in the processing using the first monitor.

According to this invention, when the first monitor cannot be used, the setting can be performed using the second monitor, and the setting can be reflected in the processing of the first monitor. At this time, in the first monitor, it is possible to select whether the setting is reflected automatically or after the inquiry to the operator of the first monitor by specifying with the specifying means. Therefore, if the latter is selected / designated by the designation means, it is possible to prevent the contents of the first monitor from changing suddenly, so that the operator can perform various actions associated with unexpected changes in the contents of the first monitor. Inconvenience can be avoided.

  For example, when this multi-monitor system is applied to a car navigation device, when two or more monitors are installed in the vehicle and both can be operated by navigation, the destination set using the rear seat monitor is displayed in front. The driver or the person sitting in the passenger seat can decide whether or not to reflect on the seat monitor. Therefore, the route displayed on the front seat monitor can be determined by designating the setting made using the second monitor so that the setting performed using the second monitor is not automatically reflected in the processing performed using the first monitor. Since it does not change suddenly, troubles to driving can be prevented.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following, a car navigation device having a plurality of monitors will be described as an example of the multi-monitor system according to the present invention. However, the present invention is not limited to a car navigation device, and two or more devices are held in many homes. It can also be applied to mobile phones, televisions, personal computers and the like.

  Next, the operation of the car navigation device as the multi-monitor system according to Embodiment 1 of the present invention configured as described above will be described with reference to the flowchart shown in FIG.

First, the desire to set the destination or stopover during running of the vehicle occurs, the rear seat, the second monitor 6 ₂ and the second input device 7 ₂ destination and stopover using the input as the processing conditions These locations are searched (step ST10). That is, when the destination and stopover using the second input device 7 ₂ is input, the data representing these destination and waypoints are, the route search unit via the second user interface processing unit 14 ₂ as the processing condition 12 is sent. The route search unit 12 reads the map data from the map data storage unit 11 based on the received data indicating the destination and the waypoint, and searches for those locations.

Next, the destination and waypoint searched in step ST10 are set as the changed route (step ST11). Next, it is checked whether or not automatic setting has been made (step ST12). That is, the first user interface processing unit 14 ₁ checks whether the automatic setting signal has been sent by the automatic setting button 5 is pressed. When it is determined that the automatic setting signal has been received, the route search unit 12 is notified accordingly. The route search unit 12, the processing conditions registered for display on the first monitor _61, that is to change the destination and stopover (step ST15). Next, the guide route is recalculated according to the changed destination and waypoint, and the guide route obtained by this recalculation is drawn on the map (step ST16). By the above processing, the ability to automatically change the first display content of the monitor ₆₁ by the second monitor 6 ₂ and the second input device 7 _second operation is realized.

In step ST12, if the automatic setting has not been made is determined, then, as shown in FIG. 3, with a message 30 indicating the destination and stopover on the first monitor ₆₁ is displayed, the route change The button 31 is displayed and an inquiry is made (step ST13). Next, it is checked whether or not the route change button 31 has been pressed (touched) (step ST14). Here, if it is determined that the route change button 31 has not been pressed, that is, no response to the inquiry has been made, the process waits until the route change button 31 is pressed while repeatedly executing step ST14. In the case of not performing route change, by pressing a reset button (not shown), you can return the display of the first monitor ₆₁ to the original state. On the other hand, when it is determined that the route change button 31 has been pressed, that is, a response to the inquiry has been made, the processes of steps ST15 and ST16 described above are executed.

In parallel with the above operation, although not shown in the flowchart of FIG. 2, the processing of displaying constantly the second monitor 6 ₂ state to the first monitor ₆₁ is executed. That is, the second user interface processing unit 14 _2, the signal being transmitted to the second monitor 6 _2, whether the image signal based on the map data read from the map data storage unit 11, read out from the disk drive device 8 determining whether the video signal based on the video data, and sends the state signal to the first user interface processing unit 14 _1.
