[Problems to be solved by the invention]
However, when using a plurality of cameras, it is necessary to link the shutters, so that it takes time and effort to prepare for shooting, and the shooting location and target may be limited. When a compound eye camera is used, it is easy to link the shooting operations between the cameras, but the shooting direction axis of each camera is fixed.
[0005]
Conventionally, when photographing a stereoscopic image, photographing is performed using a compound eye camera or a plurality of cameras, but the depth position on the display screen of the stereoscopic image corresponding to the focal position of the photographed subject does not change. In order to change the position of the camera, it is necessary to change the positional relationship between the subject and the camera by changing the shooting position or the combination of the equipment. This requires a very complicated operation.
[0006]
SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a photographing apparatus that adjusts a focal position when photographing a stereoscopic image.
[0007]
[Means for Solving the Problems]
An imaging device according to an aspect of the present invention includes a plurality of housings that are foldably connected, and is disposed in each of the first and second housings of the plurality of housings, for shooting a subject and forming a three-dimensional image. The camera includes first and second imaging units that output a right-eye image and a left-eye image, and a movable unit that is provided in association with at least one of the first and second imaging units. At least one of the first and second photographing units changes the photographing direction in conjunction with the movement of the movable unit provided in association with the first and second photographing units based on the amount of movement of the movable unit. The focus indicated by the shooting direction is adjusted.
[0008]
Therefore, the shooting direction changes in conjunction with the movement of the movable unit, and the focus indicated by the shooting direction can be variably adjusted based on the amount of movement of the movable unit.
[0009]
Therefore, it becomes easy to focus on the subject by the amount of movement of the movable portion regardless of the position of the subject.
[0010]
The above-mentioned movable part is preferably, in conjunction with the movement, a surface of the first housing where the first imaging unit is arranged, and a surface of the second housing where the second imaging unit is arranged. A plane angle changing means for changing an angle to be formed is included.
[0011]
Therefore, the focus can be variably adjusted by changing the angle formed by the surface of the first housing and the surface of the second housing, that is, the imaging direction, in conjunction with the movement by the surface angle changing means.
[0012]
The above-mentioned surface angle changing means preferably includes a connecting portion which turns to connect the housings in a foldable manner, and the photographing apparatus further includes turning adjusting means for adjusting a turning amount, so that turning and folding can be performed. Works together with.
[0013]
Therefore, since the rotation of the connecting portion that connects the casings in a foldable manner and the folding movement are interlocked, the angle formed by the surface of the first casing and the surface of the second casing, that is, the shooting direction, is connected. The focus can be variably adjusted by changing the rotation of the unit.
[0014]
The above-mentioned rotation adjusting means preferably has a rotation drive section for rotating the connection section in accordance with externally provided information. Therefore, by giving information from the outside, the focus can be adjusted by changing the amount of rotation.
[0015]
Preferably, the above-described imaging device further includes a display unit that displays a stereoscopic image generated based on the left-eye image and the right-eye image on a screen. Therefore, the subject can be photographed while checking the stereoscopic image displayed on the display unit.
[0016]
The movable section preferably includes a photographing angle changing section for changing an angle of at least one of the first and second photographing sections with respect to the housing surface, and the photographing angle changing section changes the angle in accordance with the rotation of the connection section. Change.
[0017]
Accordingly, since the angle of at least one of the first and second photographing units with respect to the housing surface changes in conjunction with the change in the angle between the housing surfaces, the shooting direction is smaller than when only the angle between the housing surfaces changes. Can be finely adjusted, and as a result, the focus can be finely adjusted.
[0018]
At least one of the first and second photographing units described above preferably moves along the surface of the housing provided. Therefore, by moving the photographing unit along the surface of the housing, the photographing direction changes, and the focus can be variably adjusted by this movement.
[0019]
The above-mentioned focal point is preferably indicated by an intersection between axes indicating the photographing directions of the first and second photographing units. Therefore, by changing the shooting direction so that the intersection corresponds to the position of the subject, an appropriate in-focus state can be obtained.
[0020]
The above-described photographing apparatus preferably further includes a unit for displaying a relationship between the actual position of the subject and the focus. Therefore, since the relationship between the current focus position and the position of the subject can be confirmed by display, the photographing direction can be adjusted so as to be in focus while confirming the displayed relationship, and the operability is improved.
[0021]
The above-described imaging apparatus may further include a unit that calculates a focal length, and the display of the relationship between the actual position of the subject and the focal point may be based on displaying a stereoscopic image and the calculated focal length.
[0022]
The above-described photographing device is preferably mounted on a portable device.
The above-mentioned portable device preferably has information communication means, and the information of the stereoscopic image is transmitted to the outside via the communication means.
[0023]
Preferably, at least one of the above-described first photographing unit and the second photographing unit can direct the photographing direction to both the front surface and the back surface of the disposed housing surface.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the camera that captures and outputs a subject is mounted on a portable device, but the device on which the camera is mounted is not limited to a portable device. Further, a mobile phone (hereinafter, referred to as a mobile phone) is exemplified as the mobile device, but the mobile device is not limited to this.
[0025]
In the mobile phone according to the present embodiment, the photographing direction axis of the camera is changed via a movable part such as a hinge, and thereby the focal position for photographing is adjusted. Here, the photographing direction axis refers to a virtual axis that indicates the photographing direction of the camera.
[0026]
In addition, since a three-dimensional image based on image information obtained by shooting is displayed at the time of shooting, the user operates while checking the displayed three-dimensional image to change the shooting direction axis, that is, change the focus position. Can be performed.
[0027]
FIG. 1 shows an appearance of a mobile phone according to the present embodiment, and FIG. 2 shows a functional configuration. Referring to FIG. 1, a mobile phone 10 includes a housing 11 and a housing 12 that can be folded around the hinge 101 while being connected via the hinge 101. A unit 103 and a receiver 104 are mounted, and a second camera 105, a key operation unit 106, and a microphone 107 are mounted on the housing 12. The housing 11 and the housing 12 are completely folded about the hinge 101 between the surface of the housing 11 on which the first camera 102 is arranged and the surface of the housing 12 on which the second camera 102 is arranged. If it is closed.
[0028]
Referring to FIG. 2, a mobile phone 10 includes a first camera 201 and a second camera 202 each including a solid-state imaging device such as a CCD (Charge Coupled Device) that captures an object and outputs image information. A control unit 203 including a processor for centrally controlling the operation of the telephone 10, a control unit 203 is connected to the first camera 201 and the second camera 202, and image information output from these cameras is synthesized. An image processing unit 204 that performs various types of information processing, a key input unit 205 that is operated when a user inputs various types of information for control to the mobile phone 10, and information that includes a synthesized stereoscopic image or planar image. A display unit 206 for displaying, control information of the mobile phone 10, application programs, user data, and the like. Storage unit 207, wireless unit 208 for communicating with a public base station (not shown), microphone 107, receiver 104, audio input / output unit 209 including audio data encoding / decoding device (not shown), and angle detection built in hinge 101 A section 210, first and second motors 211 and 212, and a hinge motor 213 are provided.
[0029]
The display unit 206 is controlled to switch between a mode capable of displaying a stereoscopic image and a mode for displaying a planar image. Image information captured and output by the first and second cameras 201 and 202 is processed into image data for stereoscopic display by an image processing unit 203, and an image based on the image data is displayed on a display unit 206. Thus, a stereoscopic image is displayed.
[0030]
The first and second cameras 201 and 202 correspond to the first and second cameras 102 and 105, respectively, and the angle detection unit 210 is provided with a camera lens of the housing 11 and the housing 12 around the hinge 101. An angle formed between the surfaces is detected, and an angle signal S3 is output to the control unit 203. Specifically, the hinge 101 has a member that rotates concentrically, and the rotation and the folding operation of the housing are linked. Therefore, based on the rotation angle indicating the amount of rotation, it is possible to detect the angle formed between the surfaces on which the cameras of the housings 11 and 12 are arranged.
[0031]
When the control unit 203 receives the angle signal S3, the control unit 203 determines the adjustment amount of the shooting direction axis of the first camera 201 and the second camera 202 based on the angle signal S3, and outputs the control signals S2 and S3 according to the determined adjustment amount. Output to the first motor 211 and the second motor 212, respectively. The first motor 211 and the second motor 212 rotate by an angle based on the control signals S2 and S3, respectively, and the first camera 201 and the second camera 202 each have the lens pointed in conjunction with the rotation. It is adjusted to change the shooting direction.
[0032]
The angle between the surfaces of the housings 11 and 12 on which the cameras (camera lenses) are arranged is adjusted by opening and closing the housings 11 and 12 about the hinge 101 for folding. Is achieved. This opening and closing operation may be performed manually or automatically by the rotation of the hinge motor 213.
[0033]
Further, the stereoscopic image data obtained by shooting can be transferred to another device by the control unit 203 via the wireless unit 208.
[0034]
Next, the operation of the mobile phone 10 will be described.
When the subject is photographed as a stereoscopic image, the photographing is performed using the first and second cameras 201 and 202 with the housings 11 and 12 of the mobile phone 10 opened around the hinge 101 as shown in FIG. . The image synthesizing unit 204 generates information of a stereoscopic image by using information (image data for the right eye and image data for the left eye) of images having parallax, which are captured and output by the cameras 201 and 202, respectively. The generated stereoscopic image information is temporarily stored in the storage unit 207 by the control unit 203, and is displayed on the display unit 206 in response to an operation of the key input unit 205 by the user.
[0035]
At this time, the point at which the shooting direction axis 302 vertically extending from the center of the lens (not shown) of the first camera 201 and the shooting direction axis 304 vertically extending from the center of the lens (not shown) of the second camera 202 intersects indicates the focal point. , The focal point corresponds to the reference position.
[0036]
The reference position is the position when the image is displayed on the same plane as the display surface when the object is photographed and the image is stereoscopically displayed on the display unit 206 (when the object is located at the focal point). Point to. In FIG. 3, the subject 3a is photographed at the reference position. However, the subject 3b located closer to the mobile phone 10 than the intersection of the two photographing direction axes corresponding to the reference position displays a stereoscopic image on the display unit 206. In this case, the subject 3 c located on the opposite side of the cell phone 10 at the intersection of the two photographing direction axes appears to be sunk on the display unit 206.
[0037]
In the present embodiment, the user manually opens and closes the housing 11 or 12 to open and close the angle θ of the hinge 101 (the surface of the housing 11 having the lens of the first camera 201 and the second By adjusting the angle of the camera 202 with the surface having the lens, the depth position of the subject on the screen when displaying a stereoscopic image can be arbitrarily changed. For example, if the angle θ of the hinge 101 is slightly smaller than that of FIG. 3 as shown in FIG. 4, the intersection of the shooting direction axes 302 and 304 is located closer to the mobile phone 10 than that of FIG. Even if the subject 3d is in a position where it can be seen up, it can be displayed as an image of the reference position on the screen of FIG.
[0038]
Further, by changing the shooting direction of the camera in conjunction with the change of the angle θ of the hinge 101, fine adjustment of the shooting direction of the camera is possible. Specifically, the angle detector 210 detects the angle θ of the hinge 101, and the control unit 203 outputs control signals S1 and S2 based on an angle signal S3 indicating the detected angle θ. According to the control signal, the first and second motors 211 and 212 are driven to rotate by an angle corresponding to the angle θ, and the directions of the lenses of the first and second cameras 201 and 202 are changed in conjunction with the rotation. Change. As a result, adjustment is performed so that the shooting direction axis is oriented in a direction corresponding to the detected angle θ. This function will be described with reference to FIG.
[0039]
FIG. 5 illustrates the interlocking of the angle θ of the hinge 101 and the angles of the cameras 201 and 202 by the folding operation of the housings 11 and 12 around the hinge 101 having the angle detection unit 210. Drawing. Here, the angle of the camera refers to an angle of a camera lens surface (not shown) of the camera with respect to a housing surface on which the camera is arranged.
[0040]
In the function of adjusting the direction of the shooting direction axis corresponding to the angle θ detected by the angle detection unit 210, the angle of the first camera 201 and the angle of the second camera 202 Are fixed at 15 degrees, and the angle of the first camera 201 and the angle of the second camera 202 change from 15 degrees to 0 degrees, respectively, when the angle θ of the hinge 101 is between 120 degrees and 180 degrees. I do. At this time, the angle θ of the hinge 101 is 0 degree, which means that the housings 11 and 12 foldably connected by the hinge 101 are closed together on the surface provided with the lens of the camera. In this state, these two surfaces are flat with respect to 101.
[0041]
That is, the angle of the lens surface of the first camera 201 with respect to the lens surface of the second camera 202 is “(angle of hinge 101) +30 degrees” when the angle θ of the hinge 101 is 0 to 120 degrees, and the angle of the hinge 101 Is from 150 degrees to 180 degrees, "150 degrees + (angle θ of hinge 101-120) / 2 degrees).
[0042]
Next, a method for measuring the distance to the subject will be described with reference to FIG. Using the angle θ measured by the angle detection unit 210 installed on the hinge 101 and the distance 1 from the center of the hinge 101 to the center of the camera 211 (212) (the starting point of the shooting direction axis 302 (304) extending from the camera). The distance L from the center of the hinge 101 to the subject located at the focal point (the intersection of the imaging direction axes 302 and 304) is represented by L = 1 / cos (θ / 2). However, at this time, it is assumed that the distance from the hinge 101 to the starting point of the imaging direction axis of the housings 11 and 12 is both 1.
[0043]
The control unit 203 calculates the distance L according to the above-described method, and displays the calculated distance L on the display unit 206. In a focused state in which the focus is located at the position of the subject as shown in FIG. 6, the distance L indicates the distance to the subject and the focal length, but otherwise indicates only the focal length. Therefore, by confirming the depth position and the distance L on the screen of the stereoscopic image displayed on the display unit 206 at the time of shooting, the user can change the depth position on the screen of the stereoscopic image while changing the distance L, that is, The relationship between the focus and the subject position is set to the reference position state, that is, the in-focus state, while performing manual or automatic folding operation based on key input information of the key input unit 205 to change the shooting direction axis 302 (304). Can be adjusted as follows.
[0044]
Here, assuming that the distance 1 is 10 cm and the angle θ of the hinge 101 is 150 degrees, the distance L from the center of the hinge 101 to the intersection of the imaging direction axes 302 and 304 is calculated to be about 40 cm according to the following equation.
[0045]
L = (10 * cos15 / cos (150/2) + 10 * cos (150/2)) (however, the unit of the angle is degree). According to this formula, when the distance L is changed from 1 m to 2 m and there is no function of adjusting the angle of the camera, the user manually operates the housing 11 or 12 to reduce the angle θ of the hinge 101 to about It is necessary to adjust only 6 degrees from 168 degrees to about 174 degrees. It is extremely difficult to manually make such a fine adjustment of 6 degrees.
[0046]
On the other hand, if the function of adjusting the angle of the camera according to the present embodiment is used, the user manually operates the housing 11 or 12 so that the angle θ of the hinge 101 becomes about 156 degrees to about 168 degrees. It will be adjusted by 12 degrees. Thus, for the same amount of change (changing the distance L from 1 m to 2 m), the amount of operation (12 degrees) is smaller than when the amount of manual operation of the housing 11 or 12 (6 degrees) is relatively small. The greater the number, the better the operability.
[0047]
In the above-described example, the adjustment of the angle θ of the hinge 101 is performed manually, but the adjustment can be automatically performed by the hinge motor 213 as follows. In the case of the automatic operation, specifically, while holding the housing 12 having the key input unit 205 with one hand, when a cursor key indicating an upward direction of a cursor key group (not shown) of the key input unit 205 is pressed, the hinge 101 is pressed. Becomes large, the housing 11 moves in the opening direction, and when the cursor key indicating the downward direction is pressed, the angle θ of the hinge 101 becomes small and the housing 11 moves in the closing direction.
[0048]
The control unit 203 receives and processes a key operation signal, generates a control signal S4 corresponding to the key operation content, and outputs the control signal S4 to the hinge motor 213. The hinge motor 213 is, for example, a stepping motor, and is driven based on a control signal S4, and the hinge 101 rotates to change the angle θ in conjunction with the driving. The housing 11 opens and closes in conjunction with the rotation. The angle θ changes, for example, once by pressing the key once, and when the key is pressed for a long time, the angle θ changes continuously according to the pressing period.
[0049]
According to such automatic adjustment of the angle θ of the hinge 101, even when the subject is far away and it is difficult to finely adjust the angle manually, it is possible to relatively easily adjust the angle θ to the desired angle θ, and to adjust the angle θ as desired by the user. Image information for a stereoscopic image can be easily obtained.
[0050]
Also, when photographing a subject located relatively far away, the distance between the first and second cameras 201 and 202 and the hinge 101 (so that the intersection of the photographing direction axes 302 and 304 can be set far from the hinge 101). l) may be adjustable.
[0051]
Specifically, as shown in FIGS. 7A and 7B, a rod-shaped member 214 is integrally provided in the housing 11, and an end of the rod-shaped member 214 which is different from the end on the hinge 101 (not shown) side is provided. A first camera 201 is provided on the same surface as the housing 11. Since the rod-shaped member 214 extending from the first camera 201 is slidably disposed in the direction of arrow R on the side of the surface of the housing 11, the distance (l) between the first camera 201 and the hinge 101, that is, The intersection can be changed by adjusting the shooting direction. When the rod-like member 214 slides and comes closest to the hinge 101 (not shown), the rod-like member 214 is housed in a groove 215 formed on the side and upper part of the housing 11 (FIG. 7A). reference). Although the first camera 201 is shown here, the same configuration may be adopted for the second camera 202 in the housing 12.
[0052]
In order to adjust the distance (l) of the camera from the hinge 101 as described above, a part of the rod-shaped member of the housing including the camera has a structure that can be extended and contracted by sliding, so that a subject at a relatively distant position can be moved. Also in photographing, it is possible to set a focus on the position of the subject and obtain an image that does not impair the stereoscopic effect.
[0053]
Since the captured image is displayed on the display unit 206 on the spot, the state of the image (whether or not the image is at the reference position (whether the focus is set at the position of the subject) or the like) can be confirmed. It is also possible to shoot while confirming the image displayed in three dimensions.
[0054]
The state of the image (eg, whether or not the image is at the reference position) can be confirmed using the display unit 206 based on the relationship between the actual position of the subject and the focus. The display unit 206 divides the display area of the screen into two right and left parts, and the two-dimensional image based on the image information output from each of the first and second cameras 201 and 202 is simultaneously displayed in each of the divided display areas ( 8 (A) to 8 (C)).
[0055]
8A to 8C, the plane images based on the image information output from each of the first and second cameras 201 and 202 are displayed as they are in the left and right display areas, respectively, and furthermore, each of the display areas is displayed. At the center, a marker 701 indicating the position where the shooting direction axes 302 and 304 pass is displayed.
[0056]
Each image in the display area corresponds to the subject in FIG. 3, and the depth position of the image on the screen can be adjusted by looking at the positional relationship of the images on the screen. Specifically, if the marker 701 is displayed at the center position of the image in each of the display areas as shown in FIG. 8B, the formed stereoscopic image will be seen at the reference position, and the image shown in FIG. This corresponds to a state where the subject 3a is being photographed. When the left and right images appear closer to the inside of the display area than the marker 701 as shown in FIG. 8C, the corresponding stereoscopic image appears to be raised from the screen, and as shown in FIG. On the other hand, when the image is displayed left and right apart, the image appears to be located deeper than the screen.
[0057]
Therefore, by adjusting the hinge angle θ while confirming the display in FIGS. 8A to 8C, it is possible to set the intersection (focal point) of the shooting direction axes 302 and 304 at the position of the subject and perform shooting. As a result, a stereoscopic image corresponding to the reference position can be displayed.
[0058]
Further, by allowing the first camera 201 to be rotatable by the rotating unit 902 to which the camera 201 is attached as shown in FIG. 9, when shooting a planar image, the shooting direction can be either the front direction or the rear direction of the housing 11. This makes it possible to photograph a subject located not only in the front direction but also in the rear direction, and it is possible to expand the photographable range. Similarly, the second camera 202 may be rotatable.
[0059]
Although the above-described photographing apparatus has been described by taking as an example a configuration including two housings 11 and 12 that can be folded around one hinge 101, the number of housings is three or more, and these housings are connected to each other. May be applied to those configured to be foldable via a hinge. As an example, a device including three housings is shown in FIG. FIG. 10 shows a configuration in which a housing 903 is attached to the housing 11 via a hinge 904 in addition to the configuration shown in FIG.
[0060]
The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
