Description

  The present invention relates to a center console having a display unit and an operation unit at the center in the vehicle width direction of an instrument panel (dashboard), an imaging unit that captures the rear of the host vehicle, and a vehicle rear image captured by the imaging unit. The present invention relates to a display device for a vehicle including an electronic mirror monitor that displays the above.

  The vehicle display device displays an image captured by a rear camera (imaging means) mounted on the host vehicle on a monitor mounted in the vehicle interior so that the driver can check the rear of the vehicle. The state behind the vehicle can be confirmed by observing the monitor as an electronic mirror instead of a side mirror, a rearview mirror, and the like. As illustrated in FIG. 2, a technique for making it easier for the driver to check the state behind the vehicle is known.

  In Patent Document 1, in order to intuitively understand whether the video displayed on the display unit of the electronic mirror is the right rear or left rear video of the vehicle, the display unit of the electronic mirror is connected to the driver. According to the positional relationship with the imaging means, it is arranged at a position removed from the front position of the driver.

  In Patent Document 2, when the level of importance increases from the viewpoint of safety, for example, a left rear image displayed on the left end side on the panel screen arranged in front of the driver's seat is displayed from the left end side to the center side. The driver can quickly recognize the situation on the left rear.

  On the other hand, the instrument panel of the center console arranged between the driver seat and the passenger seat is provided with a display unit for displaying information output from various devices such as a car navigation device, an audio device, or an air conditioner. In addition, an operation unit for operating these various devices is provided at a position that can be reached from the driver's seat.

  By the way, the above-mentioned monitor of the electronic mirror displays a moving image in which the scenery behind the vehicle flows in the opposite direction to the scenery flow (optical flow) seen through the front window during traveling. easy.

  The driver usually faces in the direction of travel through the front window and does not always drive while keeping an eye on the electronic mirror monitor. There is no.

  However, the driver is traveling while looking at not only the scenery seen through the front window but also the instruments arranged on the instrument panel and the display contents of the display unit, and for example, changing the setting of the car navigation device, When adjusting the temperature of the air conditioner, etc., when reaching out to the operation unit, it is only a short time from the front of the vehicle to the center console to operate while checking the position of the operation unit. A move is made.

  Then, in order for the driver to check the images displayed on the front side of the vehicle and on the display unit provided on the center console, or to operate the operation unit, the driver can move between the front side of the vehicle and the display unit and the operation unit. When moving the line of sight, the line of sight is moved so as to cross the electronic mirror monitor or so that the electronic mirror monitor enters the central view side of the field of view. However, the image of the electronic mirror monitor is easily taken away.

  If it does so, there existed a subject that the display content of the display part of a center console and the operation of an operation part could not be performed quickly.

  As in Patent Document 1 described above, for example, when the electronic mirror is disposed at the upper part of the center console as a position removed from the front position of the driver according to the positional relationship between the driver and the imaging unit, Thus, even when the left rear image is displayed on the left end side in the panel screen arranged in front of the driver's seat during normal driving where the level of importance is not increased, the driver is When moving the line of sight between the display unit and the display unit, there is a possibility that the above-described problem that the image of the electronic mirror monitor is easily lost.

JP 2005-329768 A JP 2010-64691 A

  In view of this, an object of the present invention is to suppress the line of sight from being attracted to the image of the electronic mirror monitor, and to smoothly check the display content of the display unit provided in the center console and to operate the operation unit.

  The present invention relates to a center console provided with at least one of a display unit and an operation unit in a center portion in the vehicle width direction of the instrument panel, imaging means for photographing a rear side of the own vehicle, and a vehicle width direction of the instrument panel in the vehicle width direction. A vehicle display device provided with the center console or an electronic mirror monitor provided between the center console and a steering wheel and displaying a vehicle rear image taken by the imaging means, An identification information acquisition unit that acquires the estimation information estimated to visually recognize the center console, a determination unit that determines whether or not the visibility of the vehicle rear image is degraded based on the estimation information, and the determination unit And deterioration display means for reducing the visibility of the vehicle rear image based on the determination result. .

  According to the above configuration, it is possible to suppress the line of sight from being attracted to the image of the electronic mirror monitor, and to confirm the display content of the display unit provided in the center console and to operate the operation unit smoothly.

  Here, the display unit and the operation unit may be formed integrally with each other, such as a touch panel monitor, or may be provided separately. Further, the display unit and the operation unit may be provided separately for each of a plurality of functions such as a navigation function and an audio function, but may be configured as a display unit or an operation unit that also has a plurality of functions. .

  That is, at the center of the instrument panel in the center console in the vehicle width direction, for example, as a display unit or an operation unit of at least one of various devices such as a navigation device, an audio device, an air conditioner, a mail transmission / reception device, a television, and a telephone. Can be provided.

  The electronic mirror monitor can be provided at the center console or at a location between the center console and the steering wheel. For example, when the driver moves his eyes to the display unit or the operation unit of the center console, It can be provided at a position approximately the same height as the easy steering wheel.

  The said inference information acquisition means can be set as the structure which can acquire the information which the vehicle equipment and the control part (ECU) acquired, or the output information as the inference information estimated when a driver | operator visually recognizes the said center console. However, the present invention is not limited thereto, and for example, a visual motion detection means for detecting a visual motion of the center console by the driver may be used.

  As an aspect of the present invention, there is provided a restoration display means for restoring and displaying a degraded display image that has been degraded and displayed after a lapse of a predetermined time since the degradation display was started.

  According to the above configuration, the vehicle rear image that has been degraded and displayed after the elapse of a predetermined time is displayed in its original state, so that the driver can confirm the display contents or perform operations on the center console, When it is necessary to check the rear image of the vehicle from the viewpoint of giving priority to safety, such as a course change or a lane change, without having to consciously restore the degraded display image every time the line of sight is returned to The situation behind the host vehicle can be reliably confirmed by the restored vehicle rear image.

  Here, the predetermined time can be, for example, a time that is expected to be necessary when confirming the display content of the display unit or the operation location of the operation unit in the center console. The amount of information (display time, number of characters of information, etc.) and the amount of operation such as the number of pressing switches during operation can be arbitrarily set.

  It should be noted that the time expected to be required when confirming the display content of the display unit and the operation location of the operation unit is not limited to the time when the display unit and the operation unit of the center console are visually recognized, The time during which the line of sight is moved between the center console and the center console may be included.

  Further, as an aspect of the present invention, the imaging means is arranged on the vehicle side on the passenger seat side in the vehicle width direction so as to image the rear of the vehicle from the vehicle side on the center console side with respect to the driver seat in the vehicle width direction. The determination means may be configured to determine that the vehicle rear image is not degraded when the turn signal device that indicates the direction of the center console toward the vehicle side is turned on.

  According to the above configuration, in general, when the own vehicle changes its course or lane in the direction toward the center console with respect to the driver's seat, the center console in the vehicle width direction of the instrument panel or the center It can be said that the necessity of visually recognizing the vehicle rear image displayed on the electronic mirror monitor provided between the console and the steering wheel is high.

  Therefore, when the turn signal device is turned on so as to indicate the direction of the center console side to the vehicle side in the vehicle width direction, the display content of the display unit provided on the center console by the driver is displayed. Even when moving to the center console side for checking or operating the operation unit, the driver can display on the electronic mirror monitor by displaying so that the visibility of the vehicle rear image does not deteriorate. It is possible to safely change the course or change the lane while reliably viewing the displayed vehicle rear image.

  Here, for example, when the host vehicle changes its course or lane, it can be said that the driver needs to check the vehicle rear image from the viewpoint of giving priority to safety. Therefore, if it is possible to detect in advance the movement of the host vehicle that changes the course or the lane, the determination means is not limited to the case where the turn signal device is turned on as described above. Further, based on a change in the movement of the driver detected by the driver imaging camera, the vehicle rear image may be determined not to be displayed in a degraded manner.

  Further, as an aspect of the present invention, the deterioration display unit includes a calculation unit that calculates an optical flow based on a plurality of vehicle rear images captured at different times by the imaging unit, and the vehicle rear image based on the optical flow. Dynamic flow component extraction means for extracting a dynamic flow component from the inside, and dynamic flow component removal means for removing and displaying the dynamic flow component from the vehicle rear image.

  According to the above configuration, since only the dynamic flow component in the vehicle rear image is removed and the deterioration display is performed by the deterioration display means, only the region where the optical flow is likely to be taken away by the driver is displayed in a deteriorated manner. On the other hand, since the static flow component in the vehicle rear image is displayed as usual without being deteriorated by the deterioration display means, the driver can recognize the presence of a moving object such as a rear vehicle, for example. .

Here, the dynamic flow component is an object having a large relative speed with respect to the own vehicle, for example, a stationary object that is actually stationary, such as a utility pole.
Note that the static flow component is an object having a small relative speed with respect to the host vehicle, for example, a moving object traveling at substantially the same speed as the host vehicle.
Further, as an aspect of the present invention, the deterioration display means is a vehicle rear image reduction means for displaying the vehicle rear image displayed on the screen of the electronic mirror monitor in a reduced manner with respect to the screen size and displaying the deterioration. The reduced vehicle rear image reduced and displayed by the vehicle rear image reduction means is displayed on the opposite side of the center console in the vehicle width direction of the screen of the electronic mirror monitor.

  According to the above configuration, the vehicle rear image reduction means can reduce the vehicle rear image displayed on the screen of the electronic mirror monitor with respect to the screen size. When the line of sight is moved to the display unit and the operation unit provided in the display unit, the display content of the display unit can be confirmed and the operation unit can be quickly operated without drawing the line of sight to the image of the electronic mirror monitor.

  On the other hand, since the reduced vehicle rear image is displayed on the side opposite to the side having the center console in the vehicle width direction of the screen of the electronic mirror monitor, the driver is displayed while the vehicle rear image is degraded. Even so, if the reduced vehicle rear image is consciously viewed, the state behind the vehicle can be recognized, and safety can be ensured.

  According to the present invention, it is possible to suppress the line of sight from being drawn into the image of the electronic mirror monitor, and to confirm the display content of the display unit provided in the center console and to operate the operation unit smoothly.

  The left side camera 11 is provided inside the left side camera housing on the front end side through a camera bracket that protrudes outward in the vehicle width direction from the vehicle body. For example, a CCD or the like that can capture images in the visible light region, the infrared region, etc. It consists of a small color camera or the like using a CMOS as an image sensor, and outputs captured information as moving image information in real time (see FIGS. 1 and 2).

  In addition, although the door mirror (side mirror) is not provided in the side part of the vehicle of this embodiment, even if it employ | adopts the camera integrated door mirror which provided the door mirror separately from the side camera and embedded the side camera in the housing. Good.

  The driver imaging camera 12 is a small camera for capturing an image of the driver sitting in the driver's seat as viewed from the front side of the vehicle. For example, a CCD camera or an infrared camera can be used. The driver imaging camera 12 is attached to the garnish in the passenger compartment of the front pillar 57 as shown in FIG. 2 in the present embodiment, but the driver imaging camera 12 includes the operation of the driver operating the main monitor 30. In order to detect the movement of visually recognizing the monitor 30, for example, if the movement of the driver's head or left hand can be imaged, it may be arranged on the instrument panel 51, the center console 50, or the like.

  The left electronic mirror monitor 16 is composed of a liquid crystal monitor or the like, and displays an image showing a left rear state of the host vehicle generated by the image generation unit 42 described later. Such a left electronic mirror monitor 16 is disposed on the instrument panel 51 so as to be visible to the driver.

Specifically, as shown in FIG. 2, the left electronic mirror monitor 16 has a steering wheel 55 at a position between the main monitor 30 in the vehicle width direction of the instrument panel 51 and the meter panel 56 on the front side of the driver's seat. It is installed at almost the same height.
In addition, in a present Example, the instrument panel 51 shall show the dashboard arrange | positioned over the whole vehicle width direction of the front seat front part of a compartment.

  The ECU 40 includes a CPU for controlling various processes, a ROM for storing programs and parameters for executing processes performed by the CPU, a RAM as a work area for temporarily storing data generated in the process, and the like. It comprises a well-known microcomputer provided. Further, the ECU 40 includes an interface unit for connecting to an external device, and as an in-vehicle device 20, for example, an e-mail transmission / reception device 21, a car navigation device 22, an air conditioner 23, an audio device as shown in FIG. The display information acquired from the device 24 and a telephone device or the like (not shown) is displayed on the main monitor 30, and information input by a switch operation of the main monitor 30 is output to various in-vehicle devices 20.

  In such an ECU 40, image generation units 41 and 42, a determination unit 43, an electronic mirror image deterioration display processing unit 44, and an electronic mirror image deterioration display release processing that perform control processing using the vehicle display device 1 of the present embodiment. Part 45 (see FIG. 1).

The image generation units 41 and 42 have a function of performing various types of image processing, and include an image generation unit 41 for the left side camera 11 and an image generation unit 42 for the driver imaging camera 12 (see the same figure). ). The image generation unit 41 for the left side camera 11 horizontally reverses the generation process image generated based on the imaging data of the vehicle left rear landscape captured by the left side camera 11, and the vehicle left rear image corresponding to the horizontally reversed image. It has a function of processing to P1 (see FIG. 4) and displaying it on the left electronic mirror monitor 16.
The image generation unit 42 for the driver imaging camera 12 generates a driver image based on the driver imaging data captured by the driver imaging camera 12.

  The determination unit 43 receives information acquired through a plurality of information acquisition units such as a mail reception detection unit 113, an image generation unit 42 for the driver imaging camera 12, a timekeeping unit 14, and a left turn signal ON state detection unit 15 which will be described later. Whether to comprehensively display the vehicle left rear image P1 is determined based on a determination program corresponding to a plurality of patterns of determination conditions.

For example, the determination unit 43 determines whether or not the vehicle left rear image P1 is displayed in a degraded manner based on whether or not the email transmission / reception device 21 has received an email.
As a specific determination condition in this case, when the e-mail transmission / reception device 21 receives e-mail, the determination unit 43 acquires the e-mail reception detection signal output by the e-mail reception detection unit 113 and acquires the left turn signal ON. When the state blinker ON state detection signal is not acquired by the state detection unit 15, the vehicle left rear image P <b> 1 of the left electronic mirror monitor 16 is determined as “degradable display is possible”. On the other hand, when the determination unit 43 has acquired the left turn signal ON state detection signal by the left turn signal ON state detection unit 15 at the time of acquiring the mail reception detection signal output by the mail reception detection unit 113. Determines that the vehicle left rear image P <b> 1 of the left electronic mirror monitor 16 is “impossible to display degradation”.

Alternatively, the determination unit 43 determines whether or not the vehicle left rear image P1 is displayed in a degraded manner based on the posture of the driver imaged by the driver imaging camera 12.
As a specific determination condition in this case, the determination unit 43 is an attitude in which the intention of the driver to recognize the main monitor 30 is inferred based on the driver image acquired by the imaging of the driver imaging camera 12. When the left turn signal ON state detection unit 15 has not acquired a left turn signal ON state detection signal, the vehicle left rear image P1 of the left electronic mirror monitor 16 is determined as “degradable display is possible”. . On the other hand, when the determination unit 43 determines that the driver's posture is a posture in which an intention to visually recognize the main monitor 30 is determined, the left turn signal ON state detection unit 15 causes the left turn signal ON state detection signal to be detected. Is obtained, it is determined that the vehicle left rear image P1 of the left electronic mirror monitor 16 is “degradation display is impossible”.

  In addition, as a method of determining that the driver's posture is the posture in which the intention of visually recognizing the main monitor 30 is estimated based on the driver image acquired by the imaging of the driver imaging camera 12, for example, the driver is the main In order to operate the monitor 30, a posture in which the left hand is extended toward the main monitor 30 or a posture in which the head is directed to the main monitor 30 (a posture in which the head is inclined at a predetermined angle from the front to the left side of the vehicle) A plurality of posture patterns whose intent to visually recognize the monitor 30 is stored in a ROM of the ECU 40 as a main monitor visual posture pattern, registered in advance as a database, and acquired by imaging by the driver imaging camera 12 By comparing the driver's posture displayed in the image with the registered main monitor visual recognition posture pattern, the position information and angle information of both postures When the difference is included within a predetermined threshold, a method of determining that the driver intends to visually recognize the main monitor 30 can be adopted, but not limited to this method, other methods may be used. Good.

  Further, when the determination unit 43 receives the elapsed information when the time measured by the time measuring unit 14 to be described later from the deterioration display start time has passed a predetermined deterioration display time stored in the ROM, the “degradation display can be canceled”. Is determined.

  Here, the deterioration display time is the time from the start of the deterioration display of the vehicle left rear image P1 displayed on the left electronic mirror monitor 16 to the cancellation, and is a predetermined performed by the driver using the in-vehicle device 20. Estimated task completion time expected to be completed by the driver according to the task content is set. For example, the deterioration display time of the left electronic mirror monitor 16 screen at the time of mail reception is the time that the driver is expected to need when confirming incoming mail. Such deterioration display time is stored in a ROM provided in the ECU 40 as a database associated with the task item.

  The deterioration display time may be configured to be changeable by the driver for each task content.

Further, as shown in FIG. 1, the electronic mirror image deterioration display processing unit 44 performs an optical flow calculation unit 441, a dynamic flow in order to perform a process of displaying the vehicle left rear image P <b> 1 on the left electronic mirror monitor 16 screen. The component extraction unit 442 and the dynamic flow component removal processing unit 443 are configured.
For example, the optical flow calculation unit 441 sets, as a feature point, a point that can be recognized as the same part between a plurality of images taken at different times, and classifies the image into a plurality of points using the movement of the feature point as a flow vector. Calculate for each group. Such a flow vector is calculated in the entire region in the captured image.

  Here, a specific known method such as a matching method or a gradient method can be used as a specific method for calculating the optical flow, but is not particularly limited. Further, the optical flow may be calculated based on feature points obtained by performing the filtering process. As a filtering process, for example, a known process using a Gabor filter (gabor-filter) that resembles the characteristics of a human receptive field that the optical flow characteristics can be expressed more clearly in the peripheral part than in the central part in the image. Can be applied, but is not particularly limited.

  Furthermore, the dynamic flow component extraction unit 442 detects information such as the position and moving direction of the moving object in the image based on the flow vector calculated in the entire region in the captured image, but the host vehicle is traveling. Since the left side camera 11 itself is moving, the flow vector generated by the movement of the own vehicle is subtracted to remove the influence of the movement amount of the left side camera 11 itself, so that the left side camera 11 When a stationary object such as a background and a moving object such as another vehicle are detected from the vehicle left rear image P1 captured by the camera 11, and the left side camera 11 itself moves, on the left electronic mirror monitor 16 screen A stationary object displayed to flow is extracted as a dynamic flow component D.

  A technique for detecting a stationary object and a moving object from the vehicle left rear image P1 captured while the host vehicle is traveling is, for example, a known technique disclosed in a document such as “Japanese Unexamined Patent Application Publication No. 2004-56763”. Therefore, the description thereof is omitted here.

  The dynamic flow component removal processing unit 443 removes the optical flow 200b of the portion where the stationary object is displayed in the vehicle left rear image P1, that is, stops the flow of the portion, for example, and stops the vehicle left rear image P1. By removing the dynamic flow component D in the middle, the deterioration display is performed so that the driver's line of sight is not lost.

  Further, when the determination unit 43 determines that “degradation display can be canceled”, the electronic mirror image degradation display cancellation processing unit 45 cancels the degradation display of the vehicle left rear image P1 and restores the original display form.

  In addition, the main monitor 30 described above can display information at the front upper position of the center console 50, that is, the center position of the instrument panel 51 in the vehicle width direction, and the main monitor 30 extends the left hand. It is provided at a distance where 30 screens can be touched. As shown in FIG. 2, the center console 50 is provided between the driver's seat and the passenger seat in the passenger compartment, and is provided with a shift lever 52 for performing a speed change operation.

  Such a main monitor 30 performs, for example, the operation and information display of various in-vehicle devices 20 mounted on the vehicle such as the e-mail transmission / reception device 21, the car navigation device 22, the audio device 24, and the air conditioner 23. This is a small touch panel type monitor of about 5 to 8 inches, and is also used as a monitor for a television or a car navigation device 22.

  Such a main monitor 30 is configured such that a user can operate each in-vehicle device 20 by touching the screen by pressing and scrolling on the screen of the monitor.

  Specifically, the main monitor 30 is a pressure-sensitive or electrostatic input device that can output a contact position by a finger or the like as location data. However, the main monitor 30 is not limited to a liquid crystal type equipped with a backlight, but a CRT type. Or a plasma display type.

  Further, the main monitor 30 displays a top screen of the highest hierarchy displaying a list of devices to be used from among various in-vehicle devices 20, and selected from menu items displayed on the top screen. Hierarchical display method is adopted in which specific information display according to each device and multiple patterns of operation screens that allow operation are displayed, but it will guide the driver when receiving e-mail etc. When there is unexpected information that should be corrected, a guidance screen showing the information is preferentially displayed on the current display screen.

  The mail reception detection unit 113 transmits a mail reception detection signal to the ECU 40 when the e-mail transmission / reception device 21 receives a mail.

  The time measuring unit 14 measures time using a timer function for displaying time on the main monitor 30 or the like. After receiving a time measurement start signal from the ECU 40, the time measuring unit 14 starts time measurement and a predetermined time has elapsed. At this time, a time measurement completion signal is transmitted to the ECU 40.

  The winker device 15A is provided on the left side of the steering column, and the winker lever is tilted up or down depending on the direction in which the steering wheel 55 rotates from the neutral position. The winker device 15A is turned on and off according to the tilt of the winker lever. An operation switch for switching to the left, a blinker when the blinker lever tilts upward and the operation switch is turned on, a left blinker lamp that blinks when the operation switch is turned off, and a left blinker ON state detection unit 15. Yes.

  The left turn signal ON state detection unit 15 detects switching of the operation switch at the time when the steering lever is tilted upward and returned to the neutral position, and the left turn signal is output to the ECU 40 sequentially so that the left turn signal It detects that it is in the ON state.

Example 1
The vehicle display device 1 of the present embodiment has the above-described configuration. Next, the control processing (driving support processing) in Example 1 of the dual-purpose display device 1 will be described with reference to the flowchart shown in FIG. To do.
For example, when the driver turns on the ignition switch and starts the engine, the main monitor 30 and various in-vehicle devices 20 are powered on, and the main monitor 30 starts displaying guidance information to the driver. It will be in the state which accept | permits operation by a driver | operator (step S1).

  The left electronic mirror monitor 16 displays the vehicle left rear image P1 captured by the left side camera 11 (step S2). For example, as shown in FIG. 4A, the vehicle left rear image P1 is in a direction opposite to the flow of the scenery seen through the front window (optical flow 200a (see FIG. 2)). It is displayed on the left electronic mirror monitor 16 as a moving image in which the scenery behind the vehicle flows.

  The left electronic mirror monitor 16 is not limited to the operation after the driver turns on the ignition switch, but the driver operates the shift lever 52 in the “D” mode or the “R” mode, or the accelerator pedal is operated. The display may be started when it is detected that the host vehicle starts to move, such as when it is stepped on.

When the e-mail transmission / reception device 21 receives a mail, the mail reception detection unit 113 detects that (step S3), and a mail reception detection signal is transmitted to the ECU 40. When the ECU 40 receives this signal, the determination by the determination unit 43 is performed.
Specifically, the determination unit 43 determines that “degradation display is possible” when the left turn signal ON state detection unit 15 does not detect the ON state of the left turn signal switch (step S4: Yes).

  On the other hand, the determination unit 43 determines that “degradation display is not possible” while the left turn signal switch is in the ON state (step S4: No).

  Even when the determination unit 43 determines that “degradation display is not possible” as described above, when the left turn signal switch is released from the ON state because the vehicle has made a left turn or lane change to the left side, etc. The determination unit 43 determines that “degradation display is possible” (step S4: Yes).

  As described above, when it is determined in step 4 that “degradation display is possible”, as shown in FIGS. 4A and 4B, the electronic mirror image degradation display processing unit 44 displays the left electronic mirror monitor. 16, an area in which a landscape that is easily noticeable to the driver in the vehicle left rear image P <b> 1 as a moving image displayed as a moving image, that is, an optical flow of an area extracted as the dynamic flow component D by the dynamic flow component extraction unit 442. 200a is displayed in a degraded manner (step S5).

  Specifically, as shown in FIG. 4A, the vehicle left rear image P1 displays, for example, a left rear portion of the host vehicle Ca, a road surface R and a rear vehicle Cb, and a left rear landscape L such as a plant or a telephone pole. Of these, the road surface R and the surrounding landscape L are stationary objects when the host vehicle Ca is stopped, but the host vehicle Ca is traveling when the host vehicle Ca is traveling. As the vehicle travels, a landscape flow (optical flow 200a) is generated and becomes a dynamic flow component D (see the optical flow 200a indicated by the arrow in FIG. 4A).

Moreover, the optical flow 200a as shown in FIG. 2 of the road surface R (unevenness on the road surface) and surrounding scenery L (plants, utility poles, etc.) is a flow of scenery that can be seen through the windshield 58 as shown in FIG. Since it is displayed on the screen of the left electronic mirror monitor 16 so as to flow in the opposite direction to the optical flow 200b), it is easy for the driver to take his eyes when moving his line of sight to the main monitor 30. For this reason, the degradation display image P2 in which the optical flow 200a in the region extracted as the dynamic flow component D in the vehicle left rear image P1 by the dynamic flow component removal processing unit 443 is degraded is displayed on the left electronic mirror monitor 16 screen. Displayed as shown in FIG.
As a specific display mode for displaying the optical flow 200a in a degraded manner, the area extracted as the dynamic flow component D can be displayed by frame advance.

  On the other hand, the rear vehicle Cb traveling at substantially the same speed as the host vehicle Ca has a small optical flow, and thus is not extracted as a static flow component by the dynamic flow component extraction unit 442. Such a static flow component in the vehicle left rear image P1 is displayed as usual without being deteriorated in the deterioration display image P2 as shown in FIG. 4B, and when the main monitor 30 is visually recognized. In addition, the driver can be made aware of the presence of the rear vehicle through the deterioration display image P2.

Thereafter, on the main monitor 30, the sender, the subject, and the reception date and time are displayed as an outline of the received mail so as to be visually recognized by the driver, and the text content is displayed as necessary (step S6).
Note that the ringing tone for notifying the driver that the e-mail has been received is not limited to the e-mail transmission / reception device 21 at the moment when the e-mail transmission / reception device 21 receives the e-mail. It is good also as a structure which alert | reports at the time of displaying a deterioration image.

After the deterioration display is started as described above, the deterioration display image P2 is continuously displayed until a predetermined time corresponding to a mail reception confirmation task set in advance as a time necessary for confirmation of the received mail has passed (step S7: No). ).
On the other hand, when the ECU 40 detects a time measurement completion signal by the time measuring unit 14 that the predetermined time has elapsed, the determination unit 43 determines that the deterioration display by the deterioration display image P2 is “can be released” (step S7: Yes), the degraded display image P2 is restored to the normal display by the electronic mirror image degradation display cancellation processing unit 45 (step S8), and this process is terminated.

  Note that the predetermined time is, for example, about 10 to 30 seconds, which is expected to be necessary for the driver to look at the main monitor 30 and check the outline of the received mail such as the sender, subject, reception date and time. Can be set. Alternatively, a longer period of time from 30 seconds to 1 minute may be set as the time expected to be necessary for checking the entire contents of the received mail including the text content. Further, this time may be set to an arbitrary time by the driver.

(Example 2)
Next, a control process in Example 2 of the vehicle display device 1 of the present embodiment will be described with reference to the flowchart shown in FIG. 5 and FIG.
However, FIG. 5 is a flowchart showing the control processing of the vehicle display device 1 according to the second embodiment, and FIG. 6 is a schematic view of the front side of the passenger compartment where the driver operating the main monitor 30 is imaged by the driver imaging camera 12. FIG.

  For example, when the driver turns on the ignition switch and starts the engine, the main monitor 30 and various in-vehicle devices 20 are powered on, and the main monitor 30 starts displaying guidance information to the driver. It will be in the state which accept | permits operation by a driver | operator (step T1).

  Then, the left electronic mirror monitor 16 displays a vehicle left rear image P1 captured by the left side camera 11 (step T2).

  At the same time, the driver imaging camera 12 operates to start imaging of the driving vehicle as shown in FIG. 6 (step T3).

  The determination unit 43 collates the image captured by the driver imaging camera 12 with the main monitor viewing posture pattern stored in the ROM until it is determined that the driver intends to view the main monitor 30 (step T4: No).

  For example, as shown by a virtual line in FIG. 6, the driver turns his head toward the main monitor 30 or displays it on the touch panel type main monitor 30 in order to adjust the temperature of the air conditioner 23 (air conditioner). When a posture change such as extending the left hand toward the temperature adjustment switch is detected by the driver imaging camera 12 (step T4: Yes), the determination unit 43 uses the main monitor visualizing posture pattern stored in the ROM as the posture. Based on this, it is determined that the driver intends to visually recognize the main monitor 30.

  In subsequent step T5, when the determination unit 43 determines that the driver intends to view the main monitor 30, whether or not the ON state of the left turn signal switch is detected as in step S4 of the first embodiment. Accordingly, it is determined whether or not the vehicle left rear image P1 is displayed in a degraded manner.

  Specifically, the determination unit 43 determines that “degradation display is impossible” while the ON state of the left turn signal switch is detected (step T5: No), but the ON state of the left turn signal switch is detected. If not, it is determined that “degradation display is possible” (step T5: Yes).

  In step T5, when the determination unit 43 determines that “degradation display is possible”, the vehicle left rear image P1 displayed on the left electronic mirror monitor 16 by the electronic mirror image deterioration display processing unit 44 is displayed in a degraded manner ( Step T6). Note that the deterioration display process in step T6 corresponds to step S5 of the first embodiment described with reference to FIGS. 4A and 4B, and thus description thereof is omitted.

  For example, the deterioration display image P <b> 2 is continuously displayed while the driver is viewing the main monitor 30 in order to adjust the temperature by pressing the temperature adjustment switch of the air conditioner 23. (Step T7: No), after completion of temperature adjustment of the air conditioner 23, when the driver imaging camera 12 detects that the steering wheel 55 has been gripped and returned to the traveling posture facing forward (Step T7: Yes), the electronic The degradation display of the degradation display image P2 is canceled by the mirror image degradation display cancellation processing unit 45 (step T8), and the normal display is performed as in the vehicle left rear image P1, and this processing is terminated.

  As described above, the vehicle display device 1 according to the present embodiment described above includes the center console 50 having the main monitor 30 having the functions of both the display unit and the operation unit at the center in the vehicle width direction of the instrument panel 51, The left side camera 11 as an imaging means for photographing the rear of the vehicle and the center console 50 in the vehicle width direction of the instrument panel 51 or between the center console 50 and the steering wheel 55 and photographed by the left side camera 11 The display device for vehicles provided with the left electronic mirror monitor 16 which displays the vehicle left back image P1, Comprising: Detection information which detects a mail reception detection signal as prediction information estimated that a driver | operator visually recognizes the center console 50 Mail reception detection unit 113 as an acquisition means, and a driver image is acquired as inference information And a determination unit that determines whether or not the vehicle left rear image P1 is displayed in a degraded manner based on the driver imaging camera 12 as a recognition information acquisition unit (a visual recognition operation detection unit) and the mail reception detection signal or the driver image. And an electronic mirror image degradation display processing unit 44 as degradation display means for reducing the visibility of the vehicle left rear image P1 based on the determination result of the determination unit 43 (FIG. 1). reference).

  According to the above configuration, for example, as in the first embodiment, when the e-mail transmitting / receiving device 21 receives an e-mail, the driver is notified by voice or the like. In order to confirm the contents of the mail, it is assumed that the main monitor screen on which the mail contents are displayed is visually recognized. For this reason, when the e-mail is detected by the e-mail reception detection unit 113, the determination unit 43 displays the vehicle left rear image P1 in a degraded manner based on the inference information if there is no particular problem in terms of safety and the like. By performing the determination, the electronic mirror image degradation display processing unit 44 can perform the degradation display so that the visibility of the vehicle left rear image P1 is lowered.

  Further, as in the second embodiment described above, when the driver checks the display content of the main monitor 30 provided on the center console 50 or operates the driver, he / she looks between the front of the vehicle and the main monitor 30. Move. When such a line-of-sight movement operation is detected by the driver imaging camera 12, the determination unit 43 displays the vehicle left rear image P1 in a degraded manner if there is no particular problem in terms of safety or the like based on the information of the driver captured image. By performing the determination, the electronic mirror image degradation display processing unit 44 can perform the degradation display so that the visibility of the vehicle left rear image P1 is lowered.

  In this way, it is assumed that the driver visually recognizes the center console 50 and the vehicle left rear image P1 displayed on the left electronic mirror monitor 16 is displayed in a degraded manner, thereby suppressing the line of sight from being sucked into the image. In addition, the display content can be quickly confirmed and operated on the main monitor 30 provided in the center console 50, and safe operation can be ensured.

  Furthermore, every time the driver moves his line of sight between the front of the vehicle and the main monitor 30, the driver does not feel uncomfortable with the moving image displayed on the left electronic mirror monitor 16, and the driver concentrates on driving. Can drive comfortably.

  On the other hand, even when the line of sight is moved to the main monitor 30, when it is necessary to check the situation behind the vehicle by the left electronic mirror monitor 16, such as when turning right or left or changing lanes, the left electronic mirror monitor Since the vehicle rear left image P1 displayed in 16 is displayed in a normal manner without the deterioration display of the vehicle left rear image P1, the safety can be ensured.

  According to the aspect of the present invention, the electronic mirror image deterioration display canceling processing unit as the restoration display means for restoring and displaying the deterioration display image P2 in which the deterioration display of the vehicle left rear image P1 is displayed after a predetermined time has elapsed after starting the deterioration display. 45 (see FIG. 1).

  According to the above configuration, the deterioration display image P2 is displayed in the original state after a predetermined time has elapsed, so that the driver confirms the display content on the main monitor 30 or completes the operation. Since it is not necessary to consciously restore the display of the degraded display image P2 every time the line of sight is returned to the camera, the screen of the left electronic mirror monitor 16 is confirmed from the viewpoint of giving priority to safety, such as changing the course or changing the lane. When it is necessary to do so, the situation behind the host vehicle can be reliably confirmed by the restored vehicle left rear image P1.

  According to the aspect of the present invention, the determination unit 43 is configured to determine that the vehicle left rear image P1 is not deteriorated when the left turn signal ON detection unit 15 detects that the left turn signal is turned on. (See FIG. 1).

  According to the above configuration, when changing the course or lane in the left direction, the driver tilts the turn signal lever upward to turn the left turn signal on. Even if the line of sight is moved, the driver can safely change the course while reliably viewing the left rear vehicle image P1 displayed on the left electronic mirror monitor 16 by not displaying the left rear vehicle image P1 in a degraded manner. And can change lanes.

  Further, according to the aspect of the present invention, the electronic mirror image deterioration display processing unit 44 serves as a calculation unit that calculates the optical flow 200a based on the plurality of vehicle left rear images P1 captured at different times by the left side camera 11. As an optical flow calculation unit 441 and dynamic flow component extraction means for extracting the dynamic flow component D from the vehicle left rear image P1 having the dynamic flow component D and the static flow component based on the magnitude of the optical flow. Dynamic flow component extraction unit 442 and a dynamic flow component removal processing unit 443 as dynamic flow component removal means for removing and displaying the dynamic flow component D from the vehicle left rear image P1. Yes (see FIG. 1).

  According to the above configuration, only the dynamic flow component D in the vehicle left rear image P1 displayed on the left electronic mirror monitor 16 by the electronic mirror image degradation display processing unit 44, that is, driving in the vehicle left rear image P1. For example, when the driver moves his / her line of sight to the main monitor 30, the line of sight is attracted to the video image of the left electronic mirror monitor 16 because the driver can display only a region where the optical flow is large. In addition, it is possible to quickly confirm and operate the display contents on the main monitor 30.

  On the other hand, since the static flow component such as the rear vehicle Cb traveling at a speed close to the own vehicle Ca in the vehicle left rear image P1 is displayed as usual without being deteriorated, the driver may Even during the deterioration display of the left rear image P1, the existence of the rear vehicle Cb can be reliably recognized, and safety can be ensured.

The vehicle rear image reduction means corresponds to a reduced display processing unit 450 described later, but the present invention is not limited to the configuration of the above-described embodiment.

For example, as a deterioration display unit according to another embodiment, a reduced display processing unit 450 that performs a reduction display process on the screen of the left electronic mirror monitor 16 is displayed as an electronic mirror image deterioration display as indicated by a virtual line block in FIG. The processing unit 44 may be provided.
As shown in FIG. 7, the reduced display processing unit 450 reduces the vehicle left rear image P1 on the screen of the left electronic mirror monitor 16, and reduces the vehicle left rear image P3 as a reduced display image of the reduced display. Is displayed at a position on the opposite side (the steering wheel 55 side) of the main monitor 30 with respect to the central portion of the screen of the left electronic mirror monitor 16 in the vehicle width direction.
FIG. 7 is a schematic diagram showing a left rear image after performing a reduced display process as another deterioration display process.

  As described above, the reduced display processing unit 450 can reduce the vehicle rear image P1 displayed on the screen of the left electronic mirror monitor 16 with respect to the screen size. When moving the line of sight to the main monitor 30 provided, it is possible to quickly confirm the display content of the main monitor 30 without the line of sight being drawn into the image of the left electronic mirror monitor 16.

  On the other hand, the reduced vehicle rear image P3 is displayed on the side opposite to the side having the center console 50 in the vehicle width direction of the screen of the left electronic mirror monitor 16, that is, on the right side of the vehicle. Even while the deterioration display is being performed, if the reduced vehicle rear image P3 is consciously viewed, the contents can be recognized and safety can be ensured.

  Note that the vehicle left rear image P1 is displayed at a reduced magnification with respect to the size of the screen as long as the driver's line of sight is not attracted and the magnification is such that the presence of the rear vehicle can be confirmed by gazing. This reduction rate may be arbitrarily set by the driver.

Further, as a deterioration display processing unit according to still another embodiment, as shown in FIG. 8, the display may be blurred on the screen of the left electronic mirror monitor 16.
FIG. 8 is a schematic diagram showing a deteriorated display image P4 after performing a blurring process as another deteriorated display process. In addition, the area | region shown with the dot in FIG. 8 shall show the area | region which performed the blurring process.

  The blurring process (mosaic process) can be performed by applying a known principle. For example, an image is divided into a plurality of rectangular areas, and one arbitrary pixel among a plurality of pixels included in each area. Arbitrary methods such as processing to reduce the luminance difference between adjacent pixels in the image, or processing to obtain an average density value of a plurality of pixels included in a predetermined area, or adopting an arbitrary method can do.

  Note that the degradation display image P4 may be subjected to blurring processing on the entire image, but in this embodiment, as shown in FIG. 8, the dynamic flow component extraction unit 442 performs the motion in the vehicle left rear image P1. The dynamic flow component D is extracted, and the dynamic flow component D is displayed as degraded by performing blurring processing as one aspect of the dynamic flow component removal processing by the dynamic flow component removal processing unit 443 described above. .

  In addition, for example, as shown in a degradation display image P5 shown in FIG. 9, the overall brightness of the vehicle rear left image P1 may be lowered and displayed in a degraded manner. Thus, the method of displaying the vehicle left rear image P1 in a degraded manner is not particularly limited.

  Furthermore, as another embodiment of the vehicular display device 1, the vehicular display device 1 may appropriately include a deterioration display switch indicated by reference numeral 17 in FIG. 1 and a deterioration release switch indicated by reference numeral 18. The deterioration display switch 17 is a switch that forcibly displays the vehicle left rear image at the driver's will by pressing of the driver, and the deterioration cancel switch 18 cancels the deterioration display of the vehicle left rear image that has been deteriorated. It is a switch to do.

  Further, as another embodiment of the vehicle display device 1, information used when the determination unit 43 determines whether or not the vehicle left rear image P <b> 1 is displayed in a degraded manner includes the mail reception detection unit 113, the driver imaging camera 12, Not only the information acquired from the left turn signal ON state detection unit 15, but information acquired from other detection units may be used, and the determination unit 43 is not limited to adopting the above-described determination condition, and may perform other determinations. Conditions may be employed.

  For example, using the GPS (Global Positioning System) function of the car navigation device 22 for measuring the position of the vehicle using an artificial satellite, the vehicle has approached an intersection scheduled to turn left within a predetermined distance or less. When it is detected, as in the case where the left turn signal ON state detection signal is acquired by the left turn signal ON state detection unit 15, other determinations such as determining that the vehicle left rear image P1 of the left electronic mirror monitor 16 is not deteriorated and displayed are performed. Conditions may be employed.

  In addition, when the above-described driver imaging camera 12 is employed as the driver detection unit as another embodiment, not only the movement of the driver's hand or head is imaged but, for example, the driver's eyeball (black eyes) ) To capture the direction in which the driver is gazing, and the region to be imaged is not particularly limited as long as the driver can recognize that the driver visually recognizes the main monitor 30.

Further, the driver motion detection means is not limited to the driver imaging camera 12, and for example, a proximity sensor that detects a driver's movement by measuring a distance to the driver may be used.
In addition, since the vehicle is a right-hand drive vehicle, the vehicle display device 1 of the present embodiment is applied to a device provided on the left side. However, in the case of a left-hand drive vehicle, the vehicle display device 1 is not provided on the left side but on the right side. You may apply to the equipment provided. The vehicle display device of the present invention is not limited to being applied to either the left or right device, but may be applied to the left and right devices.

  As described above, the present invention provides, for example, a center console provided with at least one of the display unit and the operation unit in the center part in the vehicle width direction of the instrument panel, the imaging unit that captures the rear of the host vehicle, Vehicle display provided with the center console in the vehicle width direction of the instrument panel or an electronic mirror monitor provided between the center console and a steering wheel and displaying a vehicle rear image taken by the imaging means Useful for the device.
