Description

The present invention relates to a lens device and an imaging device capable of stereoscopic photography.

Patent Document 1 discloses a stereoscopic imaging optical system in which two optical systems are arranged in parallel with a predetermined distance (baseline length) separated from each other, and two image circles are imaged in parallel on one image sensor. There is. The longer the baseline length, the stronger the stereoscopic effect can be felt by the viewer of the video. In addition, the baseline length that allows you to feel a natural three-dimensional effect is determined according to the distance to the object, and if you shoot with a baseline length in the range of about 1/20 to 1/100 of the distance to the object, a natural stereoscopic effect You can get a feeling. If the baseline length is longer than this range, the stereoscopic effect is too strong, while if the baseline length is shorter than this range, the stereoscopic effect is weakened. To change the baseline length, the two optics need to be closer to or farther from each other. However, when images of two optical systems are arranged side by side on one image sensor to form an image, the images cannot be separated beyond the light receiving range of the image sensor, and on the other hand, the two images cannot be brought close to each other so as to overlap each other.

Therefore, in Patent Document 2, by deviating the diaphragms of the optical systems of the right eye and the left eye with respect to their respective optical axes, the baseline length can be set without moving the positions of the two images arranged on the image sensor. A stereoscopic imaging optical system that can be changed is disclosed.

However, in the stereoscopic imaging optical system disclosed in Patent Document 2, the baseline length cannot be changed with the aperture open. Further, in this stereoscopic imaging optical system, the range in which the baseline length can be changed is limited to the range of the open diameter of the diaphragm. Further, in the stereoscopic imaging optical system disclosed in Patent Document 1 and Patent Document 2, since two independent optical systems are inserted in the lens mount, the baseline length, which is the distance between the two optical systems, is increased. Needs to increase the diameter of the lens mount.

The average distance between the human eyes is about 60 to 65 mm, and in order to obtain a more natural stereoscopic effect similar to that of the human eye, it is necessary to use an optical system having the same baseline length. However, in order to realize this, it is necessary to make the aperture of the lens mount larger than 60 mm, so that the lens device and the image pickup device become large.

Therefore, an object of the present invention is to provide a small lens device and an imaging device capable of obtaining a natural stereoscopic effect by appropriately setting the baseline length.

The lens device as one aspect of the present invention has a first optical system, a second optical system arranged in parallel with the first optical system, and a lens mount portion that can be attached to the camera body. The one optical system and the second optical system each have a first optical axis, a second optical axis, and a third optical axis in this order from the object side to the image side, and the first optical system and the second optical system have the same. The distance between the first optical axes of the system is longer than the diameter of the lens mount, and the distance between the first optical system and the third optical axis of the second optical system is the lens mount. Shorter than the diameter of.

The lens base 203 is fixed to the lens mount portion 202 for connecting the lens device 200 to the camera body 110. In the present embodiment, the outer peripheral portions 231aR and 231aL of the third group lens holding members 231R and 231L are fitted to the circumferential surfaces 203aR and 203aL centered on the third optical axes OA3R and OA3L of the lens base 203. The two-group lens holding members 222R and 222L of the right-eye optical system 201R and the left-eye optical system 201L are connected to each other via connecting portions 222aR and 222aL provided on the two-group lens holding members 222R and 222L, respectively.

L1 is the distance between the first optical axis OA1R of the right eye optical system 201R and the first optical axis OA1L of the left eye optical system 201L, that is, the baseline length. The longer the baseline length L1, the greater the stereoscopic effect when viewing an image. L2 is the distance between the third optical axis OA3R of the right eye optical system 201R and the third optical axis OA3L of the left eye optical system 201L. φD is the diameter (aperture, mount diameter) of the lens mount portion 202 that can be attached to the camera body, and corresponds to the fitting diameter between the lens mount portion 202 and the camera mount portion 122. 202F is a flange surface of the lens mount portion 202.

As shown in FIG. 2, the right eye optical system 201R and the left eye optical system 201L each have a group 1 lens holding member 212 that holds the group 1 lens 210. The group 1 lens holding member 212 is fixed by the holding ring 215 and covered with a dustproof member 216 for preventing dust from entering from above the holding ring 215. The group 1 lens 210 is attached to the group 1 lens base 213 via two types of three rollers 214a and 214b so that the tilting eccentricity of the group lens holding member 212 can be optically adjusted.

The first prism 211 is attached to and adhered to the prism base 217 from the direction along the second optical axis OA2. Further, a prism mask 224 is attached to the prism surface of the first prism 211 to block light rays outside the optical path. The prism base 217 and the group 1 lens base 213 are screwed with screws (not shown). The second group lens 220 is attached to and adhered to the second group lens holding member 222 from the direction along the second optical axis OA2. Further, the second prism 221 is attached and adhered to the second group lens holding member 222 from the direction along the third optical axis OA3.

Two types of spacers 209a and 209b and a washer 218 are sandwiched between each of the two optical systems of the right eye optical system 201R and the left eye optical system 201L and the lens base 203. By adjusting the thickness of each of the spacers 209a and 209b and the washer 218, it is possible to suppress the focus fluctuation due to the variation of the two left and right optical systems and adjust the two optical systems so that they are both in the same focus position. ..

FIG. 7 is a schematic view of the focus adjustment unit of the image pickup apparatus 100. As shown in FIG. 7, the lens base 203 is fixed to the lens mount portion 202 for mounting on the camera mount portion 122 of the camera body 110 with the focus flange 204 and the focus ring (operating member) 205 sandwiched between them. The focus ring 205 is a member whose thickness changes like a cam depending on the rotation angle. By rotating the focus ring 205, the distance between the focus flange 204 and the lens base 203 can be changed.

As described above, the focus ring 205 is formed with cam shapes having different thicknesses according to the rotation phase. The right eye optical system 201R and the left eye optical system 201L are fixed to the lens base 203, and when the focus ring 205 is operated, the lens base 203 moves back and forth. That is, the cam shape of the focus ring 205 is sandwiched between the lens base 203 and the lens mount portion 202, so that the lens base 203 moves back and forth according to the rotation of the focus ring 205.

With such a configuration, the entire right eye optical system 201R and left eye optical system 201L of the lens device 200 can be extended or extended. That is, by operating the focus ring 205, it is possible to adjust the focus of both the right eye optical system 201R and the left eye optical system 201L. As a result, focus adjustment (focusing) can be performed, and the right eye optical system 201R and the left eye optical system 201L can be focused at the same time. The focus of the right eye optical system 201R and the left eye optical system 201L can be adjusted independently.

Since the group 1 lens 210 of the lens device 200 of the present embodiment has a larger lens diameter as the lens on the object side, the width direction size of the lens device 200 also spreads in a trumpet shape toward the object side. Therefore, when the focus ring 205 is arranged outside the group 1 lens of the left and right optical systems, the diameter of the focus ring 205 becomes large. If the outer diameter of the focus ring 205 protrudes below the bottom surface of the camera, it may interfere with mounting on a tripod. Further, when the optical system is composed of a wide-angle lens such as a fisheye lens, if the focus ring 205 is arranged near an object of the lens device 200, the hand operating the focus ring 205 may be reflected in the angle of view. On the other hand, when the diameter of the focus ring 205 is large, there is an advantage that the operation torque can be easily transmitted and the operation feeling is improved, and there is an advantage that a minute operation becomes easy.

Therefore, in the lens device 200 of the present embodiment, the focus ring 205 is arranged on the image plane side of the reflection surface of the first prism 211, and the reflection of the first prisms 211R and 211L when viewed along the first optical axis. It is placed so that it overlaps the surface. Further, the focus ring 205 is rotatably arranged coaxially with the lens mount portion 202. Further, the three-group lenses 230R and 230L are arranged inside the inner diameter of the focus ring 205. In the present embodiment, the focus ring 205 is arranged at a position where it overlaps with the first prisms 211R and 211L when viewed along the first optical axis. As a result, it can be made smaller than the focus ring 205 is arranged in the vicinity of the 1st group lenses 210R and 210L, and the outer diameter of the focus ring 205 is prevented from protruding below the bottom surface of the camera body (of the camera body). Does not protrude below the bottom). Further, by arranging the focus ring 205 coaxially with the lens mount portion 202 and arranging the lens of the third optical axis inside the inner diameter of the focus ring 205, it is possible to secure the same operability as a conventional monocular interchangeable lens. Can be done.

The focus ring 205 is not limited to the focus adjustment function (operation member for focus adjustment), but includes a zoom ring (operation member for adjusting the angle of view), an aperture ring (operation member for aperture adjustment), and the like. It is also possible to replace it with an operation ring that has the function of. In that case, the lens base 203 is directly fixed to the focus flange 204 and the lens mount portion 202 without sandwiching the focus ring 205 in between.

The three-group lenses 230R and 230L arranged on the third optical axis OA3 are arranged so as to enter the inner side of the flange surface of the camera mount portion 122 which is attached across the flange surface 202F of the lens mount portion 202. In particular, when the lens device 200 of the present embodiment is used for a mirrorless camera as a camera body 110, unlike a single-lens reflex camera, an optical refraction member such as a mirror and an operating space required for mirror lockup are not required. Therefore, it is possible to design the lens device 200 to enter the inside of the camera body 110 more than the flange surface.

Next, with reference to FIG. 5, the position of each optical axis of the lens device 200 and the positional relationship between the lens mount portion 202 and the image circle on the image sensor 111 of the camera body 110 will be described. FIG. 5 is a diagram showing the positional relationship between the lens device 200 and the image circle.

On the image sensor 111 of the camera body 110, two image circles, a right eye image circle ICR imaged by the right eye optical system 201R and a left eye image circle ICL imaged by the left eye optical system 201L, form an image in parallel. tie. It is preferable to set the size of the image circles and the distance between the image circles so that the two image circles do not overlap each other as much as possible. For example, consider a region in which the light receiving range of the image sensor 111 is divided into left and right halves at the center, the center of the right eye image circle ICR is substantially in the center of the right region of the light receiving range, and the left eye image is approximately in the center of the left region of the light receiving range. It is preferable to set so that the centers of the circle ICLs are located respectively. The optical system (right eye optical system 201R and left eye optical system 201L) of the present embodiment is an all-around fisheye lens (wide-angle fisheye lens), and the image formed on the imaging surface has an angle of view of approximately 180 °. It becomes a copied circular image, and two circular images are formed on each side.

The image of the subject is captured side by side with the right eye image (first image) formed via the right eye optical system 201R and the left eye image (second image) formed via the left eye optical system 201L. An image is formed on the element 111. The image sensor 111 converts the image (optical signal) of the imaged subject into an analog electric signal. The A / D converter 112 converts the analog electric signal output from the image sensor 111 into a digital electric signal (image signal). The image processing unit 113 performs various image processing on the digital electric signal (image signal) output from the A / D converter 112.

The display unit 114 displays various types of information. The display unit 114 is realized by using, for example, an electronic viewfinder or a liquid crystal panel. The operation unit 115 has a function as a user interface for the user to give an instruction to the image pickup apparatus 100. When the display unit 114 has a touch panel, the touch panel also constitutes one of the operation units 115. The storage unit 116 stores various data such as image data that has been image-processed by the image processing unit 113. The storage unit 116 stores the program.

The diameter is 21 mm. When the right eye optical system 201R and the left eye optical system 201L are arranged so that the second optical axis OA2 extends in the horizontal direction, the baseline length L1 becomes 60 mm, which is substantially equal to the eye width of an adult. Further, the diameter ΦD of the lens mount portion 202 can be made shorter than the baseline length L1.
