[Brief explanation of the drawing]

[0011] [Figure 1] This is a block diagram showing the outline configuration of the terminal device of the embodiment. [Figure 2] This is a block diagram showing the outline configuration of the in-vehicle device and terminal device in the embodiment. [Figure 3] This is a flowchart showing the image display control process in the terminal device of the embodiment. [Figure 4] This figure shows an example of a mask image from the embodiment. [Modes for carrying out the invention]

[0012] Next, an embodiment for carrying out the present invention will be described with reference to Figure 1. Figure 1 is a block diagram showing the schematic configuration of the terminal device of the embodiment.

[0013] As shown in Figure 1, the terminal device T of the embodiment has a display means 4 and is a terminal device T that can be attached to and detached from a mobile device mounted on a mobile body.

[0014] The terminal device T comprises an image generation means 1A that generates an image to be displayed on the display means 4, and a control means 1 that controls image generation in the image generation means 1A according to each of a plurality of applications, including a pre-set specific application. When the terminal device T is mounted on the mobile body mounting device and the mobile body is in motion, the control means 1 controls the image generation means 1A to reduce the visibility of part or all of the specific application image to be generated according to the specific application on the display means 4, or to make part or all of the image invisible on the display means 4.

[0015] As described above, according to the operation of the terminal device T of the embodiment, when the terminal device T is attached to a mobile device and the mobile device is in motion, the image generation means 1A is controlled to reduce the visibility of the specific application image in the display means 4, or to make the specific application image invisible in the display means 4. Therefore, when a terminal device T that is detachable from the mobile device is attached to the mobile device and used for image display, it is possible to realize, for example, display restrictions during movement that take safety into consideration. [Examples]

[0016] Next, specific embodiments corresponding to the above-described embodiments will be explained with reference to Figures 2 to 4. The embodiments described below are examples in which the present invention is applied to an in-vehicle system that includes, for example, an in-vehicle unit mounted on a vehicle and a terminal device that can be attached to the in-vehicle unit and can also be used independently, where the terminal device and the in-vehicle unit cooperate to perform various processing tasks.

[0017] Furthermore, Figure 2 is a block diagram showing the general configuration of the in-vehicle device and terminal device of the embodiment, Figure 3 is a flowchart showing the display processing in the terminal device of the embodiment, and Figure 4 is a diagram showing an example of a mask image of the embodiment.In Figures 2 and 4, the same component numbers as those used in the terminal device T of the embodiment shown in Figure 1 are used for each component of the embodiment that corresponds to the component of the terminal device T.

[0018] As shown in FIG. 2, the in-vehicle system SS of the embodiment includes an in-vehicle machine M provided, for example, on a center console or dashboard of a vehicle, and a portable terminal device T that can be attached to the in-vehicle machine M and can also be used alone. At this time, the terminal device T may be realized as, for example, a tablet-type terminal device, or may be realized as a so-called smartphone.

[0019] Then, as shown in FIG. 2, the in-vehicle machine M of the embodiment is connected to a vehicle speaker 16, a camera 14, and an in-vehicle network 15 installed, for example, in a vehicle on which the in-vehicle system SS of the embodiment is mounted, respectively. It includes a mounting portion BS used for mounting the terminal device T, a wireless communication portion 10, a control portion 11 composed of a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., and an amplifier portion 12 connected to the vehicle speaker 16. At this time, the camera 14 corresponds to an example of the "imaging means" of the present application.

[0020] At this time, the camera 14 is a camera that captures an image with the front, rear, and inside of the vehicle, etc., which are to be visually recognized by the driver of the vehicle as driving support information, as the imaging range. Under the control of the control portion 11, the imaging range is cyclically imaged as necessary, and the image data as the imaging result is output to the control portion 11. Further, the control portion 11 acquires information indicating the state of the vehicle, such as speed data indicating the speed of the vehicle and back gear data indicating that a so-called back gear is engaged in the vehicle, from the in-vehicle network 15. Thereby, the control portion 11 controls the camera 14 so that, for example, when the back gear data is acquired, the result of imaging the rear of the vehicle is included in the image data. On the other hand, the mounting portion BS includes a connection portion (not shown) for making a wired electrical connection with the terminal device T, and the terminal device T is mounted on the mounting portion BS.

[0021] In the above configuration, when the terminal device T is not mounted, the wireless communication unit 10 controls, under the control of the control unit 11, the reception from the terminal device T of a sound signal indicating the sound of the content reproduced in the terminal device T or a voice signal indicating the voice of the application executed in the terminal device T. Further, the amplifier unit 12 outputs, under the control of the control unit 11, the sound signal and the voice signal to the vehicle speaker SP for sound emission. In these operations, the control unit 11 controls the reception of each of the sound signal and the voice signal from the terminal device T by the wireless communication unit 10 and controls the sound emission mode from the vehicle speaker SP.

[0022] In addition to the above, when a terminal device T is installed, the control unit 11 outputs the image data acquired from the camera 14 to the terminal device T via the connection part of the installation unit BS. Furthermore, if the vehicle status acquired from the in-vehicle network 15 satisfies the conditions set in advance for the image data to be displayed as an interrupt image on the display 4 of the terminal device T, the control unit 11 generates image interrupt request data requesting the terminal device T to display the interrupt image and outputs it to the terminal device T via the connection part. Moreover, if the vehicle speed indicated by the speed data acquired from the in-vehicle network 15 exceeds a pre-set driving restriction threshold, the control unit 11 generates driving restriction instruction data indicating that the speed has exceeded the driving restriction threshold and outputs it to the terminal device T via the connection part. At this time, the threshold speed corresponding to the driving restriction threshold is a speed that has been set in advance as a threshold speed at which, from the standpoint of safe driving, it is necessary to restrict the display of things like videos that would attract the driver's attention (in other words, distract the driver from driving) on ​​the display 4 of the terminal device T, which will be described later, that the driver sees while driving at a speed above the threshold speed. The above display restriction will be hereinafter referred to as the "Display Restriction of the Embodiment." In this case, if the vehicle's speed is below the above driving restriction threshold (including when temporarily stopped or stopped (i.e., when the speed is zero)), the display restriction of the embodiment will not be performed. In addition to these, when a terminal device T is installed, the control unit 11 controls the amplifier unit 12, etc., based on various data exchanged with the terminal device T via the connection unit. Even when a terminal device T is connected, the image data, image interrupt request data, driving restriction instruction data, and various other data may be exchanged with the terminal device T via the wireless communication unit 10.

[0023] On the other hand, as shown in the lower part of Figure 2, the terminal device T of the embodiment is a terminal device T that is used when attached to an in-vehicle unit M as described above, but can also be used independently, and is composed of an attachment unit 7 used for attachment to the in-vehicle unit M, a control unit 1 consisting of a CPU, ROM and RAM, etc., an image generation unit 1A that generates an image to be displayed on the display 4 under the control of the control unit 1, a wireless communication unit 2, a recording unit 3 consisting of a recording medium such as an HDD (Hard Disc Drive) or SSD (Solid State Drive), a display 4 consisting of a liquid crystal display, etc., an operation unit 5 consisting of a touch panel or operation buttons, etc., and a speaker 6. In this case, the control unit 1 corresponds to an example of the control means 1 of the embodiment and an example of the "first acquisition means" and "second acquisition means" of this application, respectively, the image generation unit 1A corresponds to an example of the image generation means 1A of the embodiment, and the display 4 corresponds to an example of the display means 4 of the embodiment.

[0024] In the above configuration, the mounting unit 7 is equipped with a detection unit 7A that, for example, physically detects that the terminal device T has been mounted on the mounting unit BS of the in-vehicle unit M. When the terminal device T is mounted on the in-vehicle unit M, the detection unit 7A outputs a mounting detection signal to the control unit 1 indicating that it has been mounted. As a result, the control unit 1 recognizes that the terminal device T has been mounted on the in-vehicle unit M. The mounting unit 7 is also equipped with a connection unit (not shown) for wired electrical connection with the in-vehicle unit M, and this connection unit may also serve as the detection unit 7A. In this case, the power supply for operating the terminal device T mounted on the in-vehicle unit M may be supplied from the in-vehicle unit M to the terminal device T via the connection unit.

[0025] On the other hand, the recording unit 3 records multiple application programs (hereinafter simply referred to as "applications") that can be executed in the terminal device T under the control of the control unit 1, and content data (content data including images and the sound of the above content) that can be played back by said applications. Furthermore, the recording unit 3 also records a cooperation application program (hereinafter simply referred to as "cooperation application") that can be executed in the terminal device T under the control of the control unit 1 and that enables cooperation between the terminal device T and the in-vehicle unit M. This cooperation application is configured so that when the terminal device T is connected to the in-vehicle unit M via the wireless communication unit 2, various settings of the in-vehicle unit M, such as the gain and equalization of the amplifier unit 12, can be changed via the operation unit 5 of the terminal device T. Furthermore, when the terminal device T is attached to the in-vehicle unit M, it is configured so that the image generation means 1A executes predetermined display control processing related to the image displayed on the display 4 in response to image interrupt request data and driving restriction instruction data received from the in-vehicle unit M. The collaborative application is preferably run continuously in the foreground or background while wireless communication is established between the terminal device T and the in-vehicle unit M.

[0026] In addition to these, the recording unit 3 records a display restriction list that shows a list of applications that are subject to display restrictions in this embodiment, among the multiple applications that can be executed on the terminal device T under the control of the control unit 1. The applications included in this display restriction list are, for example, applications that involve the display of videos or the like, which may attract the driver's attention. In this case, such videos or the like do not include, for example, simple rewriting of text data on the display 4 or switching of displayed icons.

[0027] Meanwhile, the wireless communication unit 2 controls the transmission of the sound signal and the voice signal to the in-vehicle unit M under the control of the control unit 1. At this time, the control unit 1 uses the wireless communication unit 2 to detect the communication status between the wireless communication unit 10 of the in-vehicle unit M and the wireless communication unit 1 of the terminal device T (i.e., whether or not wireless communication has been established between the wireless communication unit 10 and the wireless communication unit 1). Furthermore, the operation unit 5 generates operation signals corresponding to various operations performed by the operation unit 5 and outputs them to the control unit 1.

[0028] In these operations, the control unit 1 executes the display processing of the embodiment, including the display restriction processing of the embodiment (hereinafter, the display restriction processing of the embodiment will be simply referred to as "display restriction processing"). The display restriction processing will be described in detail later. Furthermore, the control unit 1 controls the transmission of the above sound signal and the above voice signal to the in-vehicle unit M by the wireless communication unit 2, and, when the terminal device T is mounted on the in-vehicle unit M, controls the reception of the above image interrupt request data and the above driving restriction instruction data from the in-vehicle unit M via the above connection parts (i.e., the connection parts provided on the mounting part BS of the in-vehicle unit M and the connection parts provided on the mounting part 7). Furthermore, the control unit 1 exchanges various data with the in-vehicle unit M via the wireless communication unit 2 or the connection parts of the mounting part 7 (i.e., the exchange of the above image data, the above image interrupt request data, and the above driving restriction instruction data, etc.), and controls the display of images unique to the terminal device T using the image generation unit 1A and the display 4, and the emission of sound using the speaker 6, according to the application executed in the terminal device T under the control of the control unit 1 itself.

[0029] Next, the display processing of an embodiment that is mainly executed by the control unit 1 when the above-mentioned collaborative application is launched on the terminal device T will be described in more detail with reference to Figures 2 to 4. In this case, the collaborative application may be automatically launched when the terminal device T is powered on, or it may be automatically launched when wireless communication between the terminal device T and the in-vehicle unit M is established. Furthermore, the terminal device T can run multiple applications simultaneously in the foreground and background, and here it will be described as the collaborative application and other applications each running simultaneously in either the foreground or background.

[0030] The display processing in this embodiment is executed, for example, as an interrupt process in terminal device T when wireless communication between terminal device T and in-vehicle device M is established and the collaborative application is started in terminal device T. That is, as shown in Figure 3, when the display processing in this embodiment is started, first the control unit 1 determines whether or not the above-mentioned mounting detection signal is output from the detection unit 7A (step S1). If, in the determination in step S1, the above-mentioned mounting detection signal is not output, that is, terminal device T is not mounted in in-vehicle device M (step S1: NO), then the process proceeds to the display restriction processing and the initialization processing of the interrupt image display (step S7). In step S7, if the display restriction processing or interrupt image display described later is already being executed at this stage, the control unit 1 stops these processes, and if the display restriction processing and interrupt image display are not being executed, this state is maintained. That is, the display restriction processing and interrupt image display are initialized. After step S7 is completed, the control unit 1 returns to step S1 and continues the series of processes.

[0031] On the other hand, in the monitoring of step S1, if the detection unit 7A outputs the above-mentioned mounting detection signal (step S1: YES), the control unit 1 then determines whether or not it has received the above-mentioned image interrupt request data from the in-vehicle device M (step S2). In the determination of step S2, if the above-mentioned image interrupt request data has not been received (step S2: NO), the control unit 1 then determines whether or not it has received the above-mentioned driving restriction instruction data from the in-vehicle device M (step S3).

[0032] On the other hand, during monitoring in step S2, if the in-vehicle device M has received the image interrupt request data (step S2: YES), the control unit 1 acquires the image data transmitted from the in-vehicle device M simultaneously with the image interrupt request data, and controls the image generation unit 1A to display the interrupt image based on the image data on the display 4, prioritizing it over the image of the application currently running in the foreground of the terminal device T (step S6). A typical example of an image interrupt display is the display of the rear image of the vehicle on the display 4 when the vehicle's gear is set to reverse. After that, the control unit 1 returns to step S1 and continues the series of processes. That is, the determination from step S1 onwards is repeated, and as long as the same state as the previous determination continues, the image interrupt display will continue.

[0033] In the determination of step S3, if the in-vehicle unit M has not received information indicating that the display of videos or other content that may attract the driver's attention should be restricted (in other words, that the vehicle is in motion) as the above-mentioned driving restriction instruction data (step S3: NO), the control unit 1 proceeds to step S7 described above. On the other hand, in the determination of step S3, if the in-vehicle unit M has received information indicating that the vehicle is in motion (step S3: YES), the control unit 1 then determines whether the application running in the foreground of the terminal device T at this time is subject to display restriction in the embodiment (step S4). Specifically, in the determination of step S4, the control unit 1 searches the above-mentioned display restriction list recorded in the recording unit 3.

[0034] On the other hand, if the application is not included in the display restriction list in step S4 (step S4: NO), the control unit 1 proceeds to step S7. On the other hand, if the application is included in the display restriction list (step S4: YES), the control unit 1 executes the display restriction process of the embodiment (step S5). As the display restriction process of the embodiment in step S5, the control unit 1 controls the image generation unit 1A to superimpose a mask image MK onto the image MG corresponding to the application (for example, an image MG such as a video that would attract the driver's attention), as illustrated in Figure 4. At this time, in addition to controlling the image generation unit 1A to superimpose and display the mask image MK as illustrated in Figure 4, the control unit 1 may also control the image generation unit 1A to reduce the visibility of part or all of the image MG on the display 4, or to make part or all of the image MG invisible on the display 4. In this case, the control unit 1 may also control the image generation unit 1A to stop (prohibit) the generation of the image MG itself. After that, the control unit 1 returns to step S1 and continues the series of processes. In other words, the control unit 1 repeats the determination from step S1 onward, and as long as the same state as the previous determination continues, the display restriction process will continue.

[0035] Here, the significance of the display processing in the above-described embodiment will be explained. As the terminal device T in the embodiment, for example, a smartphone or a tablet-type personal computer can be used. Since such a terminal device T can be installed anywhere and can use a wide variety of applications, even when used in a vehicle, there are situations in which it may be used, for example, by the driver of the vehicle and by passengers other than the driver. The preferred display control differs depending on whether the vehicle is used by the driver or by passengers other than the driver, for example, in terms of display restrictions on videos while the vehicle is in motion. In this embodiment, by having the terminal device T execute a linking application for linking the terminal device T and the in-vehicle unit M, it is determined whether or not the terminal device T is installed in the in-vehicle unit M. If the terminal device T is installed in the in-vehicle unit M, it is assumed that the terminal device T is being used by the driver, and display control suitable for the driver is executed. On the other hand, if the terminal device T is not installed in the in-vehicle unit M, the above-mentioned display control, which is unnecessary for passengers other than the driver, is not performed. In other words, by installing a collaborative application that performs such functions on terminal device T, it becomes possible to perform display control suitable for in-vehicle use on terminal devices such as smartphones and tablet-type personal computers that users are accustomed to using.

[0036] As described above, the display restriction processing of the in-vehicle system SS of the embodiment, mainly by the terminal device T, reduces the visibility of the image MG of the application included in the display restriction list on the display 4, or makes the image MG invisible on the display 4, when the terminal device T is attached to the in-vehicle unit M and the vehicle is in motion. Therefore, when a terminal device T that is detachable from the in-vehicle unit M is attached to the in-vehicle unit M and used for image display, it is possible to realize display restrictions while driving that take safety into consideration.

[0037] Furthermore, since the application to be subject to display restriction processing is identified using the display restriction list recorded in the recording unit 3, the necessary display restrictions can be reliably implemented.

[0038] In this case, a display permission list showing a list of applications other than those subject to the display restrictions of the embodiment may be recorded in the recording unit 3, and the display restriction processing of the embodiment may be configured to target applications other than those included in the display permission list. Alternatively, the display restriction list or display permission list may be stored in an external server device, and when determining whether a running application is subject to display restrictions, information identifying the running application may be transmitted to the server device via the wireless communication unit 2, and the verification result may be received from the server device.

[0039] Furthermore, when the terminal device T is mounted on the in-vehicle unit M and the vehicle is in motion, displaying the mask image MK superimposed on the image MG (see Figure 4) can more reliably achieve display restrictions while the vehicle is in motion.

[0040] On the other hand, even if the generation of the image MG itself is prohibited when the terminal device T is installed in the in-vehicle unit M and the vehicle is in motion, it is possible to more reliably implement display restrictions while the vehicle is in motion.

[0041] Furthermore, if the image MG subject to the display regulations in the embodiment contains content that distracts the driver of a moving vehicle, then safety while driving can be further ensured.

[0042] In this case, if the image MG subject to the display restrictions of the embodiment includes a moving image, it is possible to deter, for example, the driver of a moving vehicle from staring at the moving image.

[0043] Furthermore, if the terminal device T is not installed in the in-vehicle unit M, the system will display images that should be generated according to each of the multiple applications, regardless of whether the vehicle is in motion or not. This ensures that necessary images are displayed correctly when display restrictions are not required.

[0044] Furthermore, since the display restrictions in the embodiment are applied when the vehicle is traveling at a predetermined threshold speed or higher, the necessary display restrictions during driving can be appropriately implemented.

[0045] Furthermore, when the terminal device T is mounted on the in-vehicle unit M and the vehicle is moving in reverse, the image displayed on the display 4 is generated based on the rear image captured by the camera 14 (see Figure 2), which has an imaging range of the rear of the vehicle. This contributes to safety when reversing.

[0046] In the embodiments described above, the configuration and operation of the present invention were described for an in-vehicle system SS mounted on a vehicle. However, the present invention can also be applied to display regulations in the movement of vehicles such as motorcycles.

[0047] Furthermore, it is possible to record a program corresponding to the flowchart shown in Figure 3 on a recording medium such as an optical disc or hard disk, or to obtain it via a network such as the Internet, and then read and execute it on a microcomputer, thereby making the microcomputer function as the control unit 1 according to the embodiment.
