[0002]

2. Description of the Related Art Generally, in an automobile, the situation of the side or rear of the vehicle, which cannot be visually recognized by the driver in the direct field of view, is grasped by the indirect field of view of the mirror system. It is designed so that you can drive appropriately according to the surrounding conditions.

For example, FIG. 15 is a view showing such a mirror type indirect view visualizing device, and as shown in the drawing, door mirrors 71, 72 or fender mirrors 73 for displaying the left and right rear conditions of the vehicle on the outside of the vehicle. , 74, left and right side mirrors are installed, and a room mirror 75 that reflects the situation behind the vehicle is installed in the passenger compartment. The driver can appropriately drive while grasping the situation around the vehicle from the indirect field of view by these mirrors. In FIG. 15, reference numerals 76 and 77 are window glasses provided on the left and right doors, and 78 is a front window glass.

On the other hand, in the case of a vehicle such as a bus having a structure in which it is difficult to secure the rear view in the indirect view of the mirror system, the back view of the vehicle is photographed by the television camera and the rear view is taken. For example, reference numeral 79A or 79B
An indirect view of a camera, which is obtained by displaying on the screen of a display (monitor) installed at a position as shown in, appears.

[0005]

By the way, in the indirect visual field of the mirror system, it is difficult to sufficiently reduce the blind spot due to the limited field of view. Further, in the case of a side mirror, the mirror largely projects to the outside of the vehicle body, which hinders the vehicle body from becoming a flash surface. Furthermore, since all the mirrors have a view through the window glass 76, 77, 78, the window glass 76, 77, 78
Dirty and cloudy, and even wind glass 76, 77, 78

Therefore, it is conceivable to use the above-mentioned camera indirect field of view instead of such a mirror type indirect field of view. That is, the camera indirect view corresponding to the left and right side mirrors such as the door mirrors 71 and 72 or the fender mirrors 73 and 74 and the camera indirect view corresponding to the room mirror 75 are provided, and the side mirrors 71 and 72 that have been conventionally installed or The 73, 74 and the room mirror 74 can be omitted.

With such an indirect field of view of the camera, the field of view is widened to reduce blind spots and the like, the protrusion to the outside of the vehicle body for securing the indirect field of view is reduced, and the window glass is not affected by dirt. A good indirect view can be secured. However, in the case of using the indirect view of the camera as described above, if the blind spots are reduced and the field of view is widened, the amount of image information displayed on the display increases, and on the contrary, a dangerous factor in the image displayed on the display (for example, However, there is a problem in that it becomes difficult to immediately recognize other vehicles that run and moving bodies such as pedestrians.

The present invention was devised in view of the above problems, and it is possible to reduce the blind spots and the like so that the protrusion of the vehicle body to the outside to secure the indirect field of view can be reduced, and it is possible to surely visually recognize the field of view. It is an object of the present invention to provide a vehicle surroundings display device capable of immediately recognizing the dangerous factor of.

It is configured so that the image information from 16 can be displayed. In the case of these cameras 14, 15 and 16, the screen reversing means can be omitted since they do not replace the mirror image.

The moving body detecting means 30A is the television camera 1
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 moving object detecting CPU.
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 display image according to the degree of attention request when a moving object to be noted exists in each partitioned 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 an emphasized area screen makes an emphasized display while outputting a composite command signal 64 if there is a moving body to be emphasized in each of the fields of view (fields 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
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.

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 extended,
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.

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 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 ambient condition display device according to the first embodiment of the present invention is configured as described above, the vehicle ambient 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.
