Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an in-vehicle information device that displays an image of an operation unit on a display unit and operates the operation unit while viewing the image.
[0002]
[Prior art]
Generally, a panel-like operation unit having a plurality of buttons and volumes is arranged in an in-vehicle device. When operating the operation unit, the operator reaches the position of the button or volume while confirming the position of the button or volume with a line of sight, and selects the target button or volume. When the operator who performs the above operations is driving the vehicle, the operator must keep his / her line of sight ahead and must maintain a stable driving posture as much as possible. For this reason, it is desirable that the mounting position of the operation portion be inside the region that is naturally visible when the operator is driving (hereinafter referred to as the driving field of view).
[0003]
However, there are restrictions on the space of the vehicle, and it is substantially difficult to attach the operation unit within the driving field of view. Therefore, the operation unit must be attached at a position slightly deviated from the driving field of view. Therefore, in a state where the operator holds the line of sight forward, the operation unit is often operated by groping, and the operability is low. Regarding the operability of in-vehicle devices, a very high level is required from the viewpoint of safety. Therefore, conventionally, an in-vehicle information device has been proposed in which a display device is attached in the driving field of view and an image of an operation unit is displayed on the display device.
[0004]
A conventional example of such an in-vehicle information device will be described with reference to FIG. When it is assumed that the driver of the right-hand drive vehicle is an operator, the device main body 1 and the operation unit 2 are arranged on the left front of the operator sitting in the driver's seat. The device main body 1 is mainly an audio device including an in-vehicle CD player, and realizes operations necessary for general reproduction of a CD. The switch necessary for the operation and the replacement of the CD are performed on the front surface of the operation unit 2. A camera 3 for acquiring an image of the operation unit 2 is fixed to the ceiling of the vehicle. At this time, it is important for the camera 3 to take an image in which the operation status of the operation unit 2 is not hidden by an operator's arm or the like. For this reason, the mounting position of the camera 3 is above the front as viewed from the operation unit 2. Furthermore, the display device 4 is installed substantially vertically at a position near the front of the operator. The display device 4 displays an image of the operation unit 2 acquired by the camera 3 and is disposed in a position where the operator can view without shifting the line of sight from the front, that is, in the driving field of view A. Reference symbol B indicates the field of view when the operation unit 2 is directly viewed, and reference symbol C indicates the image acquisition range (shooting range) of the camera 3.
[0005]
According to the in-vehicle information device having the above configuration, an operation can be performed while viewing the image of the operation unit 2 displayed on the display device 4. Therefore, the operation part 2 can be operated correctly and the outstanding operativity can be exhibited. Moreover, since the display device 4 is located within the driving field of view A, there is no need to shift the operator's line of sight to the field of view B when directly viewing the operation unit 2 from the driving field of view A even when the operator is driving. This is convenient not only for checking the operating status of the device main body 1 but also for checking the operating status.
[0006]
[Problems to be solved by the invention]
However, the above prior art has the following problems. That is, the camera 3 acquires a front image of the operation unit 2 so that the operation status of the operation unit 2 can be grasped. On the other hand, when the operator looks at the operation unit 2, the operation unit 2 is viewed from obliquely above. In addition, the display device 4 displays an image from the camera 3 on a substantially vertical screen. That is, the direction in which the camera 3 displays an image, the line-of-sight direction when the operator looks directly at the operation unit, and the display direction on the display device 4 do not match.
[0007]
For this reason, depending on the position of the camera 3, the arrangement of the operation buttons 2 a at an oblique position as viewed from the operator may be displayed straight on the display device 4. In this case, the three directions of the direction in which the operator actually moves the hand, the direction of the hand movement displayed on the display device 4, and the direction of the hand movement that the operator feels as an actual feeling are all deviated. When the user moves his / her hand while looking at the display device 4, the operator falls into the illusion that his / her hand is moving in a different direction (see FIG. 16). In addition, when the operation unit 2 is arranged in a state that is not vertical but nearly horizontal, the movement of the hand in the front-rear direction is the vertical movement in the image on the display device 4. For this reason, the movement of the hand conscious of the operator himself is greatly different, and the movement of the hand of the image displayed on the display device 4 is uncomfortable.
[0008]
The disagreement between the position of the camera 3 and the viewpoint position of the operator causes a sense of incongruity not only in the movement of the operator's hand but also in the shape of the operation unit 2 itself. In particular, when the operation unit 2 has a three-dimensional operation button, it is difficult for the button to have a three-dimensional effect in an image captured from above the front. Therefore, it is different from the impression of the button when seen with the naked eye, and there is a possibility that the selection of the operation button may be confused. As described above, there is a slight difference between the visual information from the image displayed on the display device 4 and the actual operation feeling of the operator itself, and when the operation unit 2 is operated while looking at the display device 4, there is a sense of incongruity. Has occurred. For this reason, detailed operation becomes difficult, and it takes a certain amount of time before smooth operation can be performed.
[0009]
The present invention has been proposed in order to solve such a problem, and the object is to display an image corresponding to a case where the operator directly views the operation unit on the display unit. An object of the present invention is to provide an in-vehicle information device that can eliminate the uncomfortable feeling at the time of operation received from the above image, can exhibit excellent operability while viewing the displayed image, and contributes to improvement in safety.

[0022]
(2) Second embodiment ... corresponding to claims 2 and 3
[Constitution]
Next, a second embodiment corresponding to the second and third aspects of the invention will be described with reference to FIGS. FIG. 5 is a block diagram of the second embodiment, FIG. 6 is a perspective view showing the arrangement of components in the second embodiment, and FIG. 7 is a camera with the operation unit 2 as a reference point in the second embodiment. FIG. 8 is a schematic diagram showing the position 3 and the viewpoint position of the operator, and FIG. 8 shows an example of an image in the second embodiment.
[0023]
As shown in FIG. 5, in the in-vehicle information device according to the second embodiment, the operation unit 2 includes a switch matrix 21 including a plurality of operation buttons corresponding to menu items. The switch matrix 21 is controlled by the control device 7 so that only necessary ones are in a convex state and unnecessary ones are in a flat state in accordance with the menu item. Further, as shown in FIG. 6, in the second embodiment, such a switch matrix 21 is installed almost horizontally on the left side of the operator. For this reason, the camera 3 acquires the image of the switch matrix 21 from directly above, and the position data Θ1 of the camera 3 is a considerably small value (see FIG. 7). Furthermore, in the second embodiment, the display device 4 displays the image of the switch matrix 21 and the menu items in a consistent manner.
[0024]
[Function and effect]
In the second embodiment as described above, as in the first embodiment, the position data Θ1 of the camera 3 and the position data Θ2 and Φ2 of the operator viewpoint stored in the position information storage device 5 in advance are stored. From the relationship, the image acquired by the camera 3 by the image processing device 6 can be converted into an image viewed from the viewpoint of the operator and displayed on the display device 4. An example of an image obtained at this time is shown in FIG. FIG. 8A shows an image as it is acquired by the camera 3. In this image, since the switch matrix 21 in the horizontal state is projected from almost directly above, the operation buttons 2a have a circular shape without a three-dimensional effect and are planar. Therefore, even if the operation button 2a is divided into a convex state and a flat one, it is difficult to distinguish them from the image of FIG. On the other hand, FIG. 8B shows an image after image conversion by moving the viewpoint, and the operation button 2a has an oval shape and has a three-dimensional effect, which can be close to a feeling that the operator can actually see. .
[0025]
Therefore, according to the second embodiment, it is possible to accurately display the switch matrix 21 that is in a convex state according to the menu item. As a result, there is no gap in consciousness between the sense of viewing the image on the display device 4 and the sense of operation actually touching the switch matrix 21, and accurate operation is possible while viewing the image on the display means. It can be performed. Moreover, in the second embodiment, since the image of the operation button 2a and the menu item match on the display device 4, the operation status can be easily grasped and the operability can be further improved. .
[0026]
(3) Third embodiment ... corresponding to claim 4
[Constitution]
The third embodiment corresponds to the invention of claim 4, FIG. 9 is a block diagram of the third embodiment, FIG. 10 is a flowchart in the third embodiment, and FIG. 11 is the third embodiment. The example of an image in the form of is shown. Note that the arrangement of the operation unit 2, the camera 3, and the display device 4 in the third embodiment is the same as that in the second embodiment.
[0027]
As shown in FIG. 9, the third embodiment includes a hand image segmentation device 8, a three-dimensional menu generation storage device 9, and an image composition device 10 in addition to the components of the second embodiment. There is a feature. The hand image cutout device 8 is connected to the image processing device 6 and is configured to cut out only the image of the operator's hand from the images converted by the image processing device 6.
[0028]
The three-dimensional menu generation / storage device 9 generates and stores a three-dimensional menu button image corresponding to the menu item of the in-vehicle information device. The image composition device 10 is connected to the hand image cutout device 8 and the three-dimensional menu generation / storage device 9, and captures and synthesizes the image of the operator's hand and the image of the three-dimensional menu button, respectively.
[0029]
[Function and effect]
Operations until the third embodiment displays an image will be described with reference to the flowchart of FIG. First, the camera 3 acquires an image of the hand of the operator who operates the switch matrix 21 (S201). Subsequently, based on the relationship between the position information Θ1 of the camera 3 and the Θ2 and Φ2 of the operator viewpoint, the image processing device 6 converts the image acquired by the camera 3 into an image viewed from the operator's viewpoint (S202). Next, the hand image cutout device 8 cuts out only the image of the operator's hand from the image converted by the image processing device 6 (S203). On the other hand, the 3D menu generation storage device 9 generates an image of the menu button (S204), and performs a 3D process (S205).
[0030]
The image composition device 10 captures the image of the operator's hand cut out by the hand image cutout device 8 and the image of the three-dimensional menu button generated by the three-dimensional menu generation storage device 9. Then, both images are synthesized by pasting the image of the operator's hand on the image of the three-dimensional menu button to form one image (S206). Finally, the display device 4 displays the composite image (S207). Only the image of the operator's hand can be pasted and displayed on this image sent to.
[0031]
An example of the composite image at this time is shown in FIG. The image example shown in this figure has succeeded in extracting a stereoscopic effect further than the image example after the viewpoint conversion processing in the second embodiment shown in FIG. 8B. This is because when the image acquired by the camera 3 is very flat as shown in FIG. 8A, there is little image data in the depth direction, and the image processing device 6 performs viewpoint conversion processing. This is because there is a limit to bring out the three-dimensional effect.
[0032]
Further, when the camera 3 acquires the image of the switch matrix 21, if part of the image is hidden by the operator's hand, the original image data is insufficient no matter how much image processing is performed by the image processing device 6. It will be. Therefore, the image of the part that has not been acquired cannot be displayed, and the display of the image may be a worm-eaten state. In this case, a large gap is generated between the sense of operating and the sense of viewing the image displayed on the display device 4.
[0033]
The third embodiment is effective for such a problem. In other words, a highly visible virtual image that can grasp the operation status by generating a three-dimensional menu button image and combining this image with the image of the hand of the operator who is actually operating. Can be obtained. Therefore, even if the image acquired by the camera 3 is flat or incomplete, the display image can be brought close to the feeling of the operator actually looking at the operation unit, and excellent operability is ensured. can do. In addition, as an image that the camera 3 must acquire, it is sufficient that an image of the operator's hand can be obtained at a minimum. For this reason, the mounting position of the camera 3 has a high degree of freedom, and the restrictions imposed from a narrow vehicle space can be relaxed.
[0034]
(4) Other embodiments
The present invention is not limited to the above-described embodiment, and the switch configuration of the operation unit, the mounting position of the display means, and the like can be selected as appropriate. Is also applicable. Furthermore, in the first embodiment, a configuration in which the three-dimensional menu button image and the operator's hand image as shown in the third embodiment may be employed.
[0035]
Further, an embodiment corresponding to the invention of claim 5 includes one having a function of changing the setting of position information related to the operator viewpoint. According to such an embodiment, even if the operator changes and the position of the viewpoint changes, the setting of the position information regarding the operator viewpoint can be changed as needed. Therefore, the position information of the viewpoint can be set for each operator. As a result, fine image conversion processing can be performed, and excellent operability can be exhibited for any operator.
[0036]
The viewpoint position of the operator here means the viewpoint position when the operation unit is actually seen by the operator, and the acquired image from the camera is an image from a position where the operation unit cannot be seen. There is no point in converting to. Specifically, in the field of view B when directly viewing the operation unit 2 shown in FIG. 12, the horizontal operation unit 2 is viewed almost from the side, so the image acquired by the camera 3 is displayed in this field of view B. Even if it is converted to an image equivalent to what is seen from the above, it is only converted into an image that is difficult to see.
[0037]
In such an embodiment, it is important to select a viewpoint position at which the operation unit 2 can actually be seen. As shown in FIG. 13, the virtual operator viewpoint when the operation unit 2 is actually seen is positioned. It is necessary to convert to an image viewed from this viewpoint with Θ2 and Φ2. Also in this embodiment, as in the first to third embodiments, from the relationship between the position data Θ1 of the camera 3 and the position data Θ2 and Φ2 of the operator viewpoint stored in advance in the position information storage device 5, The image processing device 6 converts the image acquired by the camera 3 into an image viewed from the operator's viewpoint, and displays this on the display device 4. An example of an image obtained at this time is shown in FIG. FIG. 14A shows an image as acquired by the camera 3. In this image, since the operation unit 2 in a horizontal state is projected from directly above, the operation button 2a has a circular shape without a three-dimensional effect, like the image in FIG. is there. On the other hand, in FIG. 14B, which is an image after image conversion processing, the operation button 2a has an elliptical shape, which can be close to the feeling that the operator can actually see.
[0038]
【The invention's effect】
As described above, according to the present invention, the image acquired by the image acquisition unit is converted into an image viewed from the operator's viewpoint, and this is displayed on the display unit. Can be close to the operation section when actually viewed, can exhibit excellent operability while viewing the displayed image, and can provide an in-vehicle information device that contributes to improving safety .
