Description

  The present invention relates to a display system.

  Normally, it is necessary to confirm safety around the vehicle when the vehicle is running. In particular, when changing the traveling direction of the vehicle, such as reversing or turning left and right, the driver needs to pay attention to the situation around the vehicle. However, when seated in the driver's seat, the driver's field of view is blocked by various components such as pillars provided in the vehicle.

In view of this, for example, a display system has been proposed in which a display display is provided on an instrumental panel inside a vehicle, and the rear view of the vehicle is displayed on the display display. As a result, by operating while viewing the image displayed on the display, the driver can move the vehicle to a desired rear position without directly viewing the rear (see, for example, Patent Document 1). .
JP-B-2-36417

  However, in the display system described in Patent Document 1, visual information through the visual field obstruction member is displayed to the driver as if there is no visual field obstruction member that causes visual field obstruction when viewed from the position of the driver. It is not projected on the visual field obstruction member itself. For this reason, for example, when making a right or left turn, the visual field is blocked by a pillar (particularly, a front pillar) provided in the vehicle in a state of being seated in the driver's seat. In such a case, the driver can lean on the windshield or move the position back and forth and right and left to see the situation around the vehicle that would be seen if there was no pillar. There was a problem of having to visually check.

  In addition, for example, when sunlight directly enters the driver's field of view while sitting in the driver's seat, a sun visor for blocking sunlight is used, but the driver's field of view is also blocked by the sun visor. There is a case. Even in this case, there was a problem that the driver had to visually check the situation around the vehicle that would be seen if there was no sun visor, such as by leaning toward the windshield. .

  The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to determine an image that would be seen if there was no visual impairment member when viewed from the driver's seat of the vehicle. It is an object of the present invention to provide a display system that can be displayed in

The display system according to the present invention includes at least one display device provided in a visual field obstruction member provided in the vehicle that is a visual field obstacle when viewed from the driver's seat of the vehicle, an imaging device that images external visual field information, and the imaging And a control device for causing the display device to display an image that will be seen at least if the visual field obstruction member is not present when viewed from the driver's seat among the external visual field information captured by the device.
According to this, on the visual field obstruction member viewed from the driver's seat of the vehicle, an image that would be seen if there was no visual field obstruction member is displayed by the display device.

In this display system, the visual field obstruction member may be a front pillar.
According to this, an image that would be seen without the front pillar is displayed by the display device provided on the front pillar viewed from the driver's seat of the vehicle.

In this display system, the visual field obstruction member may be a sun visor.
According to this, an image that would be seen without the sun visor is displayed by the display device provided in the sun visor as seen from the driver's seat of the vehicle.

In this display system, the display device may be detachable from the visual field obstruction member.
According to this, by attaching the display device at a desired position, an image that would be seen if there was no visual field obstruction member at the attached position is displayed.

In this display system, the display device is preferably an electro-optical device.
According to this, an image that would be seen without the visual field obstruction member is displayed on the electro-optical device.

In this display system, the electro-optical device may be an organic EL display device.
According to this, since the organic EL display device is light and thin, it is easy to handle the display device. Further, since the organic EL display device has a wide viewing angle, the situation around the vehicle can be easily confirmed even when viewed from the driver's seat.

That is, the 1st display D1 is affixed on the position facing the said 1st camera C1 attached to the vehicle outer approximate center part of the 1st front pillar 2a. The first display D1 displays an image based on the image data S1 output from the control device E (see FIG. 1B).

  As a result, the first display D1 displays, as an image, visual field information outside the vehicle through the first front pillar 2a that would be seen when the first front pillar 2a was not seen when viewed from the driver's seat 3.

  On the other hand, a thin second display D2 is attached to the indoor side surface 3b of the second front pillar 2b. The second display D2 is affixed to a position facing the second camera C2 attached to a substantially central portion on the vehicle exterior side of the second front pillar 2b. The second display D2 displays an image based on the image data S2 output from the control device E.

  Thereby, the second display D2 displays visual field information outside the vehicle through the second front pillar 2b that would be seen when the second front pillar 2b was not seen when viewed from the driver's seat 3 as an image.

  In addition, an operation panel section 6 in which various members such as a room light 4 and an operation switch 5 for switching on / off of the room light 4 are disposed is fixed substantially at the center of the front end of the room.

The passenger seat sun visor 8 is rotatably supported around the support shaft 9b so as to face the roof RF side or the windshield FG side.

  Then, by rotating the sun visors 7 and 8 around the support shafts 9a and 9b and lowering them to the windshield FG side (that is, the lower side in FIG. 2), the original sun visor function can be exhibited. It is like that. As described above, when light having strong luminance such as sunlight is inserted into the driver's cabin through the windshield FG and the view of the forward direction side of the driver's automobile 1 is thereby blocked, the driver can drive By lowering the seat sun visor 7 toward the windshield FG, light having strong luminance such as sunlight is prevented from directly entering the eyes of the driver.

  The driver's seat sun visor 7 having such a configuration forms a film shape on the surface 7a facing the driver's seat 3 when the driver's seat sun visor 7 is turned around the support shaft 9a so as to face the windshield FG. A third display D3 is pasted. That is, the third display display D3 is provided at a position facing the third camera C3 attached to the front end portion of the roof RF with respect to the driver's seat sun visor 7. The third display D3 displays an image based on the image data S3 output from the control device E.

The display controller CONT, for example, if the image displayed on the first display display D1 feels dazzling when viewed from the driver seated on the driver's seat 3, or the focus position is shifted and the image appears blurred, The driver himself / herself operates the first adjusting means T1 to edit the image desired by the driver. Similarly, when the display controller CONT perceives that each image displayed on the second and third display displays D2 and D3 is dazzling as viewed from the driver seated on the driver's seat 3, the display controller CONT If the image appears blurred, the driver himself / herself
And the driver adjusts the image to a desired image by operating the third adjusting means T2 and T3, respectively.

  That is, the image displayed on the first display display D1 displays an image obtained by editing the image data G1 acquired by the first camera C1 by the first adjusting means T1 of the display controller CONT. The image displayed on the second display D2 displays an image obtained by editing the image data G2 acquired by the second camera C2 by the second adjusting means T2 of the display controller CONT. Further, the image displayed on the third display D3 displays an image obtained by editing the image data G3 acquired by the third camera C3 by the third adjusting means T3 of the display controller CONT.
