  In an in-vehicle device, a device that integrates a plurality of completely different functions such as navigation, television reception, and DVD is widely used. In these in-vehicle devices, each function provides an image using the entire display from each image source, and the user switches and uses a desired function.

  On the other hand, however, in-vehicle devices have emergency information that should be notified immediately, such as guidance output by a navigation system. Such emergency information is preferably output even when the entire display is being used by other functions.

  In particular, in an in-vehicle device, a situation in which the in-vehicle device cannot be freely operated, such as when a user is driving, is likely to occur. Therefore, the in-vehicle device can autonomously control display control of emergency information. Desired.

  Further, emergency information may be provided from a plurality of video sources, and competing control of emergency information is also necessary.

  If it is known in advance what functions the in-vehicle device has and what information each function outputs, it is easy to allocate screens, display in a semi-transparent manner, and resolve conflicts between information. However, the functions of the in-vehicle device are often added later, and it has been difficult to manage and control the display output in units of services and information.

  The present invention has been made in order to solve the above-described problems in the prior art and to solve the problems, and is a highly versatile display output that performs autonomous control of video obtained from a plurality of video sources with a simple configuration. It is an object to provide a control device and a display output control method.

  In order to solve the above-described problems and achieve the object, the display output control apparatus and the display output control method according to the present invention select an output video from a plurality of video sources and display a video source other than the output video. When the occurrence of emergency information, which is information that should be immediately notified to the user, is detected, at least a portion of the output video is transmitted, and at least the emergency information is displayed so as to be visible from the video source where the emergency information is generated.

  According to the present invention, it is possible to perform autonomous control of videos obtained from a plurality of video sources, and in particular, with a simple configuration capable of outputting information with high urgency generated in video sources other than the output video at the same time as the output video. There is an effect that a highly versatile display output control device and display output control method can be obtained.

  Hereinafter, a display output control device and a display output control method according to the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic configuration diagram showing a schematic configuration of an in-vehicle device 1 which is an embodiment of the present invention. As shown in the figure, the in-vehicle apparatus 1 includes therein a navigation unit 11, a television receiving unit 12, a DVD playback unit 13, an HDD content playback unit 14, a camera unit 15, an output control unit 20, a display 31, a speaker 32, A touch panel 33 and a switch 34 are provided.

  The navigation unit 11 is an in-vehicle device that sets and guides a travel route using the position of the host vehicle specified by communicating with a GPS (Global Positioning System) artificial satellite and map data stored in advance.

  The navigation unit 11 outputs the set travel route and information on guidance as video data. In addition, the navigation unit 11 functions as a video source that provides the position information of the host vehicle, the surrounding map information, information about the road, and the like as video data.

  Furthermore, the navigation unit 11 manages traffic information such as traffic jam information and accident information acquired by VICS (Vehicle Information and Communication System) and billing information by ETC (Electronic Toll Collection System), and uses these information as video data. Output.

  The television receiving unit 11 receives a television broadcast wave and outputs it as video data. In digital television broadcasting, data such as earthquake information and other disaster information and breaking information are received and output by including them in video data.

  Each of the DVD playback unit 13 and the HDD content playback unit 14 is a unit that functions as a video source that reads and plays back video data stored in a recording medium, that is, a DVD (Digital Versatile Disk) or HDD (Hard disk drive).

  The camera unit 15 is a photographing unit that photographs the surroundings of the host vehicle, and functions as a video source that outputs a photographing result as video data. It is also possible to perform image recognition on the photographing result and output the result of image recognition together.

  The display 31 is an output unit that performs display output to a vehicle occupant who is a user, and the speaker 32 is an output unit that performs audio output to the user. The touch panel 33 and the switch 34 are input means for receiving operation input from the user.

  The output control unit 20 is a control unit that performs integrated control of input and output for the user. Each video source (navigation unit 11, television receiving unit 12, DVD playback unit 13, HDD content playback unit 14, camera unit 15) performs video output assuming that each uses the entire display 31. The control unit 20 performs processing for selecting a video to be displayed on the display 31 from these video data.

  In addition, when emergency information that is information to be immediately notified to the user occurs in the video source other than the video source that is displaying the video data, the output control unit 20 at least one of the videos that are being displayed and output. The emergency information is displayed so as to be visible.

  For this reason, the output control unit 20 includes an output video selection unit 21, an emergency information detection unit 22, a transmission processing unit 23, and a priority processing unit 24 therein.

  The output video selection unit 21 is a processing unit that performs processing for selecting an output video to be displayed and output on the display 31 from the video source, and the emergency information detection unit 22 performs processing for detecting occurrence of emergency information in the video source. Part.

  The transmission processing unit 23 performs image processing using the video data being displayed and the video data in which emergency information is generated, and performs processing for creating a composite image that is visually recognized by the user as a semi-transparent state.

  The priority processing unit 24 is a processing unit that performs priority control on the transmission output based on the priority order set for each video source when emergency information occurs in a plurality of video sources.

  Next, a specific example of video output control by the output control unit 20 will be described with reference to FIG. In the example shown in FIG. 2, the user designates playback of a DVD, video data V1 having the DVD playback unit 13 as a video source is displayed at a display rate of 100%, and the HDD content playback unit 14 is set as a video source. Video data V2, video data V3 using the navigation unit 11 as a video source, and video data V4 using the television receiving unit 12 as a video source each have a display rate of 0%.

  Here, when the emergency information V3a is generated in the video data V3 that is the navigation video and the emergency information V4a is generated in the video data V4 that is the digital television video, the transmission processing unit 23 includes the video data that is the output video. The display ratio of the areas corresponding to the emergency information V3a and V4a is set to 60%, and the display ratios of the emergency information V3a and V4a are set to 40%, respectively.

This transmission process is realized by using, for example, an alpha blend. Specifically, the transmittance is α,
Displayed pixel value = pixel value of output video × (1−α) + emergency information measure × α
By obtaining the pixel value to be displayed using the above calculation formula, it is possible to display the urgent information through the display video.

  In this calculation formula, when the value of transmittance α is 0, the display rate of the output video is 100%, and transmission is not performed. When the value of transmittance α is 1, the display rate of the output video is 0%. Only the emergency information is displayed. In the example shown in FIG. 2, the transmittance is set to 40% in order to make both the output video and the emergency information visible. However, this value can be set as appropriate, and may be a fixed value. You may make it change based on it.

  In the example shown in FIG. 2, the emergency information V3a and the emergency information V4a generated by two different video sources are not overlapped in display positions, but each video source is originally independent of the emergency information display position. Therefore, the display positions of the emergency information V3a and V4a may overlap.

  When the emergency information is generated in a plurality of video sources and the display areas are overlapped, the priority processing unit 24 displays the emergency information having a high priority for the overlapped areas, so that the emergency information having a low priority is displayed. Up / down control for displaying emergency information with high priority on the top or position control for changing the display position of emergency information of a video source with low priority is performed.

  FIG. 3 is an explanatory diagram for explaining a specific example of priority control by the priority processing unit 24. In the example shown in FIG. 3, the positions of the display areas of the emergency information V3a generated in the video data V3 that is the navigation video and the emergency information V4a generated in the video data V4 that is the digital television video partially overlap. .

  Here, since the priority order of the navigation video is set higher than the priority order of the digital television video, when the priority processing unit 24 performs the vertical control, all of the emergency information V3a is displayed semi-transparently and the emergency information V4a is displayed. Is displayed only in a portion that does not overlap with the emergency information V3a.

  When the priority processing unit 24 performs position control, the emergency information V3a having a high priority is displayed at the same position as the display position in the original video data, and the emergency information V4a having a low priority changes the display position. Displayed as emergency information V4a '.

  The priority order used by the priority processing unit 24 is set for each video source. A specific example of priority setting is shown in FIG. As shown in the figure, the navigation outputs, as emergency information, a guidance output that is an output for route guidance, traffic information such as traffic congestion and regulations provided by VICS, information on ETC charging, and the like.

  In addition, emergency information is not generated when the camera shooting results are output as video data as they are. However, for example, when image recognition is performed on the shooting results, an object that may collide with the host vehicle is recognized by image recognition. In such a case, emergency information may be generated as a collision risk notice. Furthermore, in television broadcasting, earthquake information, disaster information, breaking news telop, etc. are output as emergency information.

  In the example shown in FIG. 4, priority 1 is set for navigation, priority 2 is set for camera images, and priority 3 is set for television broadcasting. Priority control is performed with the highest priority of the video source having the smallest value of.

  Next, the processing operation of the output control unit 20 will be described with reference to FIG. The flowchart shown in the figure starts when a display output request specifying one of the video sources is generated based on a user operation or autonomous determination of each unit.

  First, the output video selection unit 21 outputs video data output from the designated video source to the display 31 at a display rate of 100% on the entire surface (step S101), and the emergency information detection unit 22 outputs emergency information on other video sources. Is monitored (step S102).

  As a result, when the occurrence of emergency information is detected (step S102, Yes), the emergency information detection unit 22 determines whether emergency information has been generated from a plurality of video sources (step S103).

  If emergency information is generated from a plurality of video sources (step S103, Yes), the priority processing unit 24 performs priority control of the emergency information (step S104), and then the transmission processing unit 23 sets the emergency information. Transmission control is performed (step S105).

  The processing from step S103 to step S105 is repeated until the display of the emergency information is completed (step S106, Yes). Then, when the display of the emergency information is finished (step S106, Yes), or when the emergency information is not generated (step S102, No), it is determined whether or not a display end request has been received (step S102). S107) The processing from step S101 is repeated until a display end request is received (until YES is established in step S107).

  As described above, when the output video selection unit 21 selects and displays video data to be output from a plurality of video sources, the in-vehicle device 1 according to the present embodiment is urgent in other video sources. The occurrence of information is monitored by the emergency information detection unit 22, and when the emergency information is generated, the video data including the emergency information is displayed on the video data being displayed by the transparent process.

  Therefore, emergency information that should be notified immediately, such as guidance output by the navigation system, can be output even when the entire display is being used by another function.

  Furthermore, by using a transparent display to display a plurality of video data so that they can be viewed at the same time, each video data can be simplified without considering what information is displayed at which position. Multiple video data can be presented simultaneously with configuration and control.

  In addition, when urgent information is provided from a plurality of video sources and competes, display control is performed according to the priority set for each video source, so that the conflict can be resolved with a simple configuration and control. Therefore, even when a new function is added later, the display output can be easily managed and controlled.

  Note that the configuration and operation shown in this embodiment are merely examples, and do not limit the present invention. The present invention can be implemented by appropriately modifying its configuration. For example, in the present embodiment, the case where only the area corresponding to the emergency information is displayed semi-transparently when emergency information occurs has been described, but the entire video data where the emergency information has occurred is displayed semi-transparently (display The entire surface may be translucent.

  As described above, the display output control apparatus and the display output control method according to the present invention are useful for autonomous control of video obtained from a plurality of video sources, and in particular, the urgency level generated in video sources other than the output video. Suitable for control that outputs high information at the same time as output video.
