The moving objects (particularly, moving objects approaching a vehicle) in the images captured by the cameras 1, 12, 13 are detected, but here, as the TV cameras 11, 12, 13,
Since a stereo camera capable of measuring the distance to the object in the image is used, the moving body detection means 30A includes the television cameras 11, 12, and 13 and the images from the television cameras 11, 12, and 13. Signals 61A, 61
It is composed of a processing means (moving body detecting CPU) 31 for processing B and 61C to detect a moving body in the image.
In the moving object detection CPU 31, each display 21
The screens displayed on A, 22B, and 23C are vertically and horizontally partitioned, for example, as shown in FIG.
Among them, the own vehicle determines whether or not there is a moving body to be noted, and outputs the result as a signal 62 to the highlighting means 40. However, in FIG.
Although an example in which each section is divided is shown, the number of sections is not limited to this.

In particular, the moving object detecting CPU 3 of this embodiment
In 1, the moving demand that the own vehicle should pay attention to in each region is calculated by calculating the attention request degree of the target moving body in accordance with the distance from the own vehicle to the moving body and the approaching distance of the moving body to the own vehicle. If there is a moving object to be noted in the information signal indicating whether or not exists, add a signal according to this attention request degree,
The signal 62 is output to the highlighting means 40. The degree of attention request increases, for example, as the distance from the vehicle to the moving body is shorter, and for example, as the approaching speed of the moving body is higher.

The highlighting means 40 is a CPU for detecting a moving body.
Processing means (CPU for creating highlighted area screen) 41 that creates an highlighted area screen based on a signal 62 from 31 and image signals 61a, 61 from the television cameras 11, 12, 13.
b and 61c, and image signal synthesizing means 42 for synthesizing the image signals 63A, 63B, and 63C from the CPU 41 for creating the emphasized area screen so as to be superimposed.

The CPU 41 for creating an emphasized area screen creates an emphasized image in accordance with the degree of attention request when there is a moving body to be noted in each divided area.
The emphasized image corresponding to the attention request level is, for example, when the attention request level is low, an emphasis color (for example, a red color or a yellow color) that alerts the driver to the image area is continuously turned on, and the attention request is displayed. It is conceivable that when the degree becomes higher than a certain level, this is made to blink, and thereafter, the blinking rate becomes faster as the degree of attention request becomes higher. It is also conceivable to increase the luminance of the emphasized area and change the hue as the degree of attention demand increases.

In addition, the CPU 41 for creating a highlighted area screen displays a composite command signal 64 if there is a moving object to be highlighted for each field of view (field of view corresponding to the television cameras 11, 12, 13). Image signal 63A or 63B
Alternatively, 63C is output, and if there is no moving object to be highlighted, the composite command signal 64 is not output. The image signal synthesizing means 42 is provided with a switch function for switching whether to perform the synthesizing process for each field of view.
If the compositing command signal 64 is not output from the CPU 41 for creating the highlighted area screen, the compositing process is not performed and the image signals 61a, 61 from the television camera 11 or 12 or 13 are sent.
b, 61c as they are as TV monitor 21 or 22 or 2
3 side (actually, screen inversion means 51 or 52 or 53)
It is designed to output to. Then, regarding the field of view in which the synthesis command signal 64 is output from the emphasis area screen creation CPU 41, the emphasis display image signal from the emphasis area screen creation CPU 41 is added to the image signal 61a or 61b or 61c from the television camera 11 or 12 or 13. 63A or 63
B or 63C is combined and output to the television monitor 21 or 22 or 23 side.

By the way, the left side display 21A
Further, the mounting structure of the right side display 22A to the instrument panel 2 will be specifically described by taking the left side display 21A as an example. 7 and 8
As shown in, the display 21A is provided at the left end (near the base of the left front pillar 3) 2A of the instrument panel 2 in the vehicle interior, but is a liquid crystal type thin display and is fixed by the clasps 5A and 5B. Has been done.

That is, the instrument panel 2 is
As shown in FIG. 9, the body side substrate 1A is covered with a skin material 2B made of resin or the like.
The base ends of A and 5B are pivotally supported in the groove formed between the substrate 1A and the skin material 2B. These clasps 5
An elastic projection (a spherical projection in this example) 5H formed of a flexible material such as rubber is provided on the surface of A and 5B facing the side end surface of the display 21A, and the side end surface of the display 21A is provided. A recess 21B into which these elastic protrusions 5H are fitted is formed. The display 21A is fixed by fitting the elastic projections 5H into the recesses 21B on both end surfaces thereof and elastically sandwiching the stoppers 5A and 5B from both sides through the elastic projections 5H.

The stopper plates 5A and 5B are, as shown in FIG.
The stoppers 5A and 5B can be bent in a direction away from the side end surface of the display 21A, but these stopper plates 5A and 5B are connected to a link mechanism composed of arms 5C and 5D, as shown in FIG. That is, the arms 5C and 5D are pin-coupled to each other by the pin 5G, and the stopper plates 5A and 5B are pin-coupled to the arms 5C and 5D by the pins 5E and 5F, respectively. Then, as shown by an arrow F, the pin coupling portion (that is, the pin 5G) of the arms 5C and 5D is inserted between the body side (that is, the substrate 1A side) of the upper portion of the display 21A and the spring 5J. It is biased upward. The urging force F of the spring 5J urges the outer ends of the arms 5C and 5D (that is, the pins 5E and 5F) in directions F1 and F2 approaching each other.
1 and F2, the stoppers 5A and 5B are also displayed on the display 21.
It is urged in a direction approaching the side end surface of A.

Therefore, when the display 21A is fitted between the stoppers 5A and 5B from the front side (from below in FIGS. 8 and 9), the spring 5J is stretched,
The arms 5C and 5D increase in opening degree, the outer ends of the arms 5C and 5D are separated from each other, and the stoppers 5A and 5B are also separated from the side end surface of the display 21A as shown by a chain line in FIG. When driven, each elastic protrusion 5 of the stopper plates 5A and 5B is driven.
When H is fitted into the concave portion 21B of the side end surface of the display 21A, the display 2 as shown by the solid line in FIG.
1A is configured to be mounted.

Further, one end of a ribbon 5K is connected to a pin 5G for connecting the arms 5C and 5D to each other, and the other end of the ribbon 5K is, as shown in FIG. It is exposed to the passenger compartment. When the other end of the ribbon 5K is pulled downward, the arms 5C and 5D increase in opening degree, the outer ends of the arms 5C and 5D are separated from each other, and the stopper plates 5A and 5B are also shown by chain lines in FIG. As shown by, the display 21A is driven in a direction away from the side end surface of the display 21A, the clamp of the display 21A is released,
The display 21A is configured to be removable.

The display 22A for the right side is also constructed in the same manner, and other displays such as the display 23A can be constructed in the same manner. The left and right side displays 21A and 22A may be provided on the door trim 6 in the vehicle compartment. That is, when the display 21A for the left side is described as an example, for example, FIG.
As shown in FIGS. 1 and 12, a display 21A is provided near the base portion 6A of the left front pillar 3 of the door trim 6 in the vehicle interior. Also in this case, the above-mentioned mounting structure can be applied to the display 21A. The right side display 22A is also configured in the same manner.

Since the vehicle surrounding condition display apparatus according to the first embodiment of the present invention is configured as described above, the vehicle surrounding condition is displayed as follows. That is, each of the TV cameras 11, 12, and 13 of the image pickup means 10 photographs the indirect visual field of the situation of the left rear of the vehicle, the situation of the right rear, and the situation of the rear of the vehicle center, and the image signals 61a, 6a.
1b and 61c are output.

Such television cameras 11, 12, 13
In the indirect field of view of the camera, since a wide-angle field of view can be set by selecting a lens or the like, it is possible to reduce the blind spot by expanding the field of view in each indirect field of view. In addition, each TV camera 11, 12, 13 has a very small CC
Since the D camera is used, the protrusion of the vehicle body to the outside can be made extremely small, the flash surface of the vehicle body can be promoted, and a highly safe vehicle body surface with less aerodynamic resistance can be constructed.

The image signals 61a, 61b, 61c from the respective television cameras 11, 12, 13 are sent to the image signal synthesizing means 42 of the highlighting means 40. At this time, the television signals 11, 12, 13 are captured. If there is no moving body to be highlighted in the displayed screen, the moving body detecting CPU 31 does not output a signal indicating that there is a moving body to which the own vehicle should be noted, and the emphasizing area screen creating CPU 41 outputs the synthesis command signal. Since 64 is not output, the image signal combining means 42 of the highlighting means 40 does not combine the images, and the image signals 61a, 61b, 61c of the image pickup means 10 are directly processed by the screen inverting means 51, 52, 53 for screen inversion processing. It is then sent to the television monitors 21, 22, 23 side. Therefore,
The displays 21A, 22A, and 23A display only the actual images taken by the television monitors 21, 22, and 23. Taking the case of the television monitor 23 as an example, for example, a screen as shown in FIG. 13A is displayed on the display 23A. Reference numeral 7 is a vehicle as a moving body.

Since such an indirect view of the camera is not a view through the window glass, dirt, cloudiness, water drops, etc. attached to the window do not hinder the view, and the indirect view is always easy to see. Can be secured. Further, the height level of each of the displays 21A, 22A, and 23A is set to the height of the meter cluster that the driver always visually recognizes, and is in a field of view closer than the door mirror, and the screen is almost in the driver's viewpoint. Since the display 21A, 22A, and 23A are installed so as to face, the driver can easily visually recognize these displays 21A, 22A, and 23A without having to move a large line of sight, which also greatly contributes to safe driving.

In this embodiment, although not particularly omitted, the rearview mirror 75 can be omitted by providing the display 23A. In this case, the visual recognition area of the front window is enlarged and the indirect field of view is increased. The area can be improved. On the other hand, each TV camera 11, 1
If there is a moving body to be highlighted in the screens captured by 2 and 13, the moving body detecting CPU 31 outputs a signal indicating that there is a moving body to which the own vehicle should pay attention, and the CPU 41 for creating the highlighted area screen. Outputs a combination command signal 64 and a highlighted display image signal 63A, 63B or 63C. Therefore, the image signal synthesizing means 42 performs the required image synthesizing, adds the highlighted display image signal 63A or 63B or 63C to the image signals 61a, 61b and 61c of the image pickup means 10, and then the surface inverting means 51, The screen is inverted through 52 and 53 and sent to the television monitors 21, 22 and 23. For example, on the screen showing the rear of the vehicle center,
When the highlighted display 8 is added to the area indicated by the shaded area in (B), the screen as shown in (C) of FIG. 13 is displayed on the display 23A in the case of the television monitor 23. In addition, in the structure shown in (B) and (C) of FIG. 13, the division of the emphasis region is divided into two vertically and four horizontally.
For the sake of convenience, the number of sections is shown as a small number.

Highlighting 8 shown in FIGS. 13B and 13C.
In the area of, for example, a predetermined warning color (for example, a reddish or yellowish color) is continuously lit when the attention demand is low, and blinks when the attention demand is higher than a certain level. , The blinking speed increases as the attention demand increases. As a result, even if the amount of image information displayed on the display device is increased by widening the field of view to reduce the blind spots, a dangerous factor in the image displayed on the display device (for example, another vehicle running). And a moving body such as a pedestrian) can be immediately recognized, which facilitates the driver to drive safely while quickly grasping the surrounding situation.

Also, in this embodiment, the television camera 1
Since a stereo camera capable of measuring the distance to the object in the image is used as 1, 12, and 13, the moving body detection unit 30A can be configured to use these stereo cameras, and the cost of the moving body detection unit 30A can be increased. In addition, the screen area of the surroundings of the vehicle detected by the image pickup unit 10 and the screen area for detecting the moving body can be easily matched, and the moving body can be detected and highlighted. Can be done more easily and accurately.

As described above, when the stereo camera is used as the image pickup means 10, for example, the information of the stereo camera can be used for automatic control of the vehicle such as automatic steering and automatic braking, and the vehicle is equipped with various equipments. Can contribute to the suppression of manufacturing cost. Of course, it is not always necessary to use a stereo camera for the image pickup means 10 as in this embodiment, and a single camera which is not a stereo camera camera, such as the moving object detection means 30B shown in FIG. On the other hand, on the other hand, other sensors 32 for obtaining information about the moving body are provided, and instead of the information from the information of the stereo camera, the degree of danger about the moving body in the image is calculated from the division of these sensors 32. It may be configured to detect. The image pickup means 10 is used as these sensors 32.
In addition to using a television camera separate from the above camera, for example, one using reflection of ultrasonic waves, one using a radar laser, one using a passive triangular distance sensor, and the like are conceivable.

The number and arrangement of the television cameras as the image pickup means 10 and the television monitors as the display means are not limited to those in the above-mentioned embodiment, and at least the image signal from the television camera has an emphasized area. By using a display mode in which image signals are combined and displayed, it is possible to contribute to the improvement of various indirect visual fields. In addition, highlighting when there is a moving object is to simply turn on the corresponding area or blink at a constant speed,
It is not necessary to change the degree of emphasis depending on the degree of risk, and even in this case, the effect of being able to immediately recognize a dangerous factor in the image can be obtained.

[0041]
