The present invention can quickly perform shooting control with a desired effect in a situation where the right hand and left hand are inconvenient, such as when a photographer aims at a subject, does not miss a release chance, and shoots while paying attention to camera shake. An imaging apparatus configured as described above is provided.

  Hereinafter, a preferred embodiment will be described using a camera to which the present invention is applied according to the drawings. An example in which the present invention is applied to a single-lens camera is shown as a first embodiment in the form of a block diagram in FIG.

  Here, an embodiment of the present invention will be described by taking an interchangeable lens camera as an example of the photographing apparatus. However, it is not necessary to be an interchangeable lens type, and there is no problem even if the present invention is used for a compact camera, a portable device with a photographing function, or the like. Such an interchangeable lens type camera can shoot using various lenses depending on the subject to be photographed, so it is close to the subject of the present invention other than general subjects such as people and landscapes. Users who want to shoot beautiful things often use such a camera. In such a lens-interchangeable camera, a desired lens 20 is attached to the camera body 10 and a subject image is guided to the imaging unit 2 to shoot, but a plurality of zoom lenses are provided on the lens 20 side. A zoom control unit 26d for switching the position of the lens element to perform zoom control, a focus control unit 26e for controlling the position so that the subject is in focus by moving the focusing lens, and the brightness of the captured subject image A diaphragm control unit 26f for controlling the height is provided. While these lens and aperture control positions are determined by the position determination units 25a and 25b, the control unit 21 uses the control data and programs recorded in the recording unit 27 via the drive units 24a and 24b such as motors. Control. There are many models that can be manually adjusted by an operation unit 23 such as a lens ring, and an operation with a focus on not only the zoom position (angle of view) but also the blurring effect by the focus position and the aperture is enabled.

  There is an example in which various operation switches and (operation ring) ring members are provided in such a lens portion to enable a plurality of operations. Here, in particular, the operation unit is assumed to be an operation ring (ring member) that rotates along the lens barrel, and this is also capable of a shift operation as will be described later. Here, two of 23a and 23b are illustrated.

  The rotation of the operation ring is suitable for analog operations such as focusing and zooming, and for selecting one of many operations. In addition, because of the miniaturization of the camera, the operation ring shift has a smaller operation range than the rotation operation, but it is suitable for quick and simple operations such as switching between modes and functions while maintaining focus posture. .

  On the other hand, on the camera body side, there is an operation unit 6 such as a switch that allows the user to perform various operations. Since an important operation of the photographing apparatus is an operation at the time of photographing, a release button for photographing a still image is preferentially arranged at a position where it can be operated with the index finger of the right hand. Using these, shooting operations can be performed, and using other switches, dials, and the like, it is also possible to change shooting parameters such as exposure correction, shutter speed and sensitivity setting, and focus position change. A touch panel can also be used by assisting such operations. In particular, the present invention assumes a touch operation that can be operated with the thumb of the right hand, as will be described later.

  The camera 10 further displays an image on the imaging unit 2 that converts an image input from the interchangeable lens into an electrical signal, and a part that displays the imaging result (such as the eyepiece display unit 30 and the display unit 8 on the rear panel). Then, an image is recorded in the recording unit 4. Such a series of control is performed by the control unit 1 including an integrated circuit such as a microcomputer in accordance with a program recorded in the recording unit 4, and the integrated circuit has a signal that can perform image processing necessary for the display and recording. A processing circuit is also formed.

  In addition, there is a face detection unit 3 that detects a face portion of a subject using an image signal from the imaging unit 2, and detects a shift in focus from the contrast and phase difference signal of such an important image part, and an exposure amount. Perform shooting control to switch the adjustment amount. The eyepiece display unit enlarges the display image of a small liquid crystal panel, organic EL panel, etc. with a dedicated optical system so that it can be seen and can be observed by looking into the viewfinder, so it is not affected by external light In addition, an image can be confirmed, and by adjusting the diopter of the optical system, it is possible to perform good observation according to the diopter of the user.

  These adjustment amounts can be switched by the parameter control unit 1d. The signal processing unit 1 incorporated in the control unit can display the imaging result on the display unit 8 including a liquid crystal display or an EL panel so that the user can take a picture while viewing the display unit 8 using the eyepiece display unit 30 or the rear panel. To process.

  A touch panel 8b is formed on the display unit 8, and if the displayed subject image is touched on the display unit, an icon displayed at that position can be selected. It has been described that the lens is provided with a ring member that can be shifted in the optical axis direction and that can rotate along the outer periphery of the lens frame. 1c and 1d functional units are provided. In addition, a display control unit 1e is provided to display an image with changed parameters, an icon, and the like on the display unit. In addition, the control unit 1 can perform image conversion filter processing that corrects distortion and lateral chromatic aberration of the photographing lens and performs image processing. Furthermore, special effect filter processing that emphasizes or suppresses a specific color or contrast is also possible. These are image processing controls performed by a specific program, but can also be configured in hardware.

  In the present embodiment, the interchangeable lens 20 and the camera body 10 can be separated by an engagement mechanism generally called a bayonet mount. In the camera system 1, the configuration that allows the camera body 2 and the lens barrel 10 to be separated from each other is not limited to the present embodiment. For example, the configuration that is generally referred to as a screw mount using a screw mechanism is used. Also good. Further, the camera body 2 and the lens barrel 10 may be configured to be separable by a mechanism using a fitting or a magnet.

  In this embodiment, the interchangeable lens unit 20 is assumed to have a configuration as shown in FIG. The interchangeable lens 20 has a mechanism for holding an optical system member 26a composed of a plurality of lenses and the like with respect to the fixed frame 28 of the lens barrel. The form of the optical system member 26a held by the lens barrel 28 may include a diaphragm, a prism, a mirror, a filter and the like in addition to the lens.

  The lens 26a closest to the image side of the optical system member 26a is a focusing lens in this example. In general, a part or all of the optical system of the photographic lens is relative to the lens frame base. The in-focus distance is changed by relatively moving in the optical axis direction. Hereinafter, of the optical system member 26a, a member that moves in the optical axis direction when the focusing distance is changed is referred to as a focusing optical system member 26b.

  The focusing optical system member 26b is held by a focusing frame disposed so as to be movable back and forth in the optical axis direction relative to the fixed frame 28. The focusing frame is driven in the optical axis direction by an actuator (not shown).

  The configuration of the actuator is not particularly limited, but it is configured with a screw disposed substantially parallel to the optical axis, a stepping motor that rotates the screw, and a nut that is screwed into the screw. Then, explanation is omitted. The focusing frame that holds the lens 26b is engaged with the nut, and the movement of the lens 26b attached to the focusing frame is controlled by rotating the aforementioned screw by a stepping motor or the like. Other types such as a linear motor may be used.

  In addition, the operation portion 23 described above is an operation ring (ring member) in particular, and the fixed frame 28 disposed inside the operation ring 23 is urged at a position facing the ridge portion. Members and balls 29 are provided, and are arranged at a plurality of locations in the circumferential direction. The ball can protrude outward from the outer peripheral surface of the fixed frame 28 and is urged radially outward by an urging member that is a leaf spring.

  When the operation ring 23 is located at the first position, the ball abuts on the first slope portion of the protrusion, and when the operation ring is located at the second position, the ball Abuts against the second slope of the part. Since the protruding portion has a substantially triangular cross section, the ball always abuts on either the first inclined surface portion or the second inclined surface portion regardless of the position of the operation ring 23.

  Therefore, when the operation ring 23 is located closer to the front of the movable range as shown in FIG. 2B, the operation ring 23 is attached to the front by the ball that contacts the first slope portion. And is abutted against one end of the movable range at the first position and positioned.

  On the other hand, when the operation ring 23 is positioned closer to the rear of the movable range as shown in FIG. 2A, the operation ring 23 is urged rearward by a ball that is in contact with the second slope portion. In the second position, the second end is brought into contact with the other end of the movable range and positioned.

  Therefore, in the lens barrel 30 of the present embodiment, when no external force is applied to the operation ring 23, the position of the operation ring 23 in the optical axis direction is either the first position or the second position. . For example, in the state where the operation ring 23 is located at the first position, when the external force applied backward to the operation ring 23 is weaker than the urging force generated by the urging member and the ball, the external force is If it disappears, the operating ring returns to the first position. Further, for example, in a state where the operation ring 23 is located at the first position, if the external force applied backward to the operation ring 23 is stronger than the urging force generated by the urging member and the ball, the operation ring 23 is Move to the second position.

  It rotates without applying such a special force in the direction of rotation about the optical axis. Although not shown, rotation is detected by an electrical signal by an encoder such as a photocoupler or a rotating blade, and the position of the first position or the second position is indicated as 23c. Can also be detected by a photocoupler, a magnetic sensor, or a mechanical switch.

  Here, the configuration using the negative force member and the ball has been described. Of course, it is possible to obtain the same effect by using an electromagnet or a spring, and it goes without saying that the present invention is also applicable to such an application. .

  As described above, the rotation of the operation ring has a large range in which the operation ring can be rotated, and thus is suitable for fine adjustment of parameter adjustment, mode selection from many options, parameter selection, and the like. However, a shift operation with a small stroke and clear switching is preferable to a rotation operation in which the absolute position is difficult to understand for various types of switching that require simplicity.

  FIG. 3A illustrates a state where the interchangeable lens 20 having such a configuration is connected to the camera body 10. In the camera body, an image sensor 2a for converting the subject image guided from the lens unit into an electrical signal is disposed with the imaging surface perpendicular to the optical axis of the lens, and is displayed on the back of the camera body 10. A part 8 is provided.

  Accordingly, when the camera 10 to which the lens 20 is attached is held, the result is as shown in FIGS. Here, the position of the release switch 6a is highlighted.

  As shown in FIG. 3C, the user is holding, and it is preferable to perform shooting and composition confirmation without moving the position of the hand or finger as much as possible from the viewpoint of shutter chance and camera shake prevention.

  FIG. 3B shows a state in which the operation ring (ring member) is moved backward. In this case, the rotation operation of the operation ring is displayed as “MF” (manual focus) on the display unit 8. In this way, it is used for focusing, which is a basic function.

  The lens control unit 21 and the camera control unit 1 may determine the rotation detection encoder and cause the actuator to change the position of the focusing lens 26b in FIG. At this time, control is performed by the drive unit 24a and the position detection unit 25a of FIG.

  When the operation ring 23 is moved forward as shown in FIG. 3C, this ring shift operation is detected by the detection unit (sensor, encoder) of 23c in FIG. 2, and can be selected by rotating in this state. Are displayed as a list on the display unit 8.

  If you place them in a position where you can touch them with your thumb, you can quickly select them with your thumb and rotate them to enter the next fine selection and adjustment. Since the rotation operation can make full use of various factors such as the rotation amount and the angle, it is considered that the rotation operation is suitable for such fine adjustment, numerical value change, and selection from many options.

  Here, there is an icon “enlarge”. When this icon is selected, the magnification of the electronic zoom or the like is changed by a rotation operation to enlarge the subject image on the display screen.

  When the “filter” icon is selected, a mode in which special image processing (special effect filter) is performed on the image is set, and black-and-white photographs and image effects with enhanced colors can be taken. This effect can be selected by rotating operation. Since there are many such effects, it is easier to select by rotating.

  Originally, it is also possible to obtain an image with a special effect by applying an image conversion filter that corrects lens distortion and lateral chromatic aberration, or by applying a method different from the original method. Such filter operation can be enjoyed even when it is ON or OFF, and the change can be enjoyed by changing the numerical value at the time of correction. Switching between ON and OFF can be performed quickly by performing a shift operation of the operation ring, and if the numerical value is changed by rotation, the user can perform shooting using these simple operations.

  Of course, not only such correction in electrical image processing, but also a special effect may be obtained by utilizing position control of the optical system.

  For example, it is possible to perform rotational movement about the optical axis of the photographic lens or shift movement in a direction parallel to the optical axis of the photographic lens, and special effects photographing can be performed by combining these movements.

  An aberration that moves in the optical axis direction to switch between a first aberration mode that forms an image with corrected aberration from the center to the periphery and a second aberration mode that forms an image with excessive spherical aberration. You may make it have a mode switching lens.

  Further, an aberration mode switching system unit that controls movement of the aberration mode switching lens based on the shift movement of the ring member for switching between the first aberration mode and the second aberration mode. This makes it possible to quickly confirm the effect and to shoot.

  The photographing lens may be a zoom lens that includes a plurality of moving lenses that include an aperture stop and move for switching the focal length when focused at infinity. At this time, the focal length is changed by moving any of the plurality of moving lenses in conjunction with the rotational movement of the ring member, and the plurality of moving lenses in conjunction with the shift movement of the ring member. The zoom-single-focus switching system unit that performs switching to set a predetermined focal length by moving any of the above and the aperture size of the aperture stop to the maximum diameter so that zoom-single-focus switching can be performed. Good.

  Also, if you select “Sensitivity”, you can change the shooting sensitivity by rotating operation, so when shooting a dark star, you can compare the noise and the brightness of the star and select the right sensitivity. Become.

  As described above, an example of a main flow of the camera that effectively utilizes the features of the operation and rotation of the operation ring of the photographing lens unit and enables the user to perform photographing with a desired effect is shown.

  For example, in step S101, an operation of a power source performed by a power switch or the like is determined. If this is turned on, a determination is made in S102 and S111 as to whether the shooting mode or the reproduction mode.

  When the power switch is turned off, only the circuit for detecting the power switch is operated, and the other electronic circuits are turned off to enter the energy saving mode (standby mode). If the shooting mode is set by switching the touch panel or the switch, a through image is displayed in S103. In this case, the subject image signal obtained by the imaging unit is displayed on the display unit in real time, and the user can check the shooting timing, composition, and effect of changing the shooting parameter while watching this. At this timing, the state of the lens, such as the operation state of the operation ring, is sequentially confirmed, but here it is expressed by the step “lens communication” in S104.

  In S104, since a signal indicating the position of the operation ring (ring member) is acquired, it is determined in S105 whether the ring position is 2 (see FIG. 2A). In this case, S106a The camera control 1 is performed. In this embodiment, this is based on the assumption of focusing by manual focus. That is, focusing is performed by rotation (see FIG. 3B).

  When S105 is branched to N, if the ring position is 1 (see FIG. 2B), this determination is made in S106b, and the process branches to S106c to display a list of selectable mode icons on the touch panel. . This is concentrated at a position where the camera can be operated with the thumb of the right hand (arranged vertically on the right end of the display unit) as shown in FIG. Camera control 2 is performed in S106d in the mode selected here. For example, when the filter is selected and the ring is turned, the effect of the image processing is switched.

  Further, when the ring position is changed from 1 to 2, or from 2 to 1, S106b is branched to N, and control camera control 3 (S106e) corresponding to the shift operation is performed in S106e. It may be.

  Control may be performed so as to switch between applying and not applying special effects by this shift operation. If the effects of the special effect filter and the image conversion filter described above can be turned on and off, it is possible to switch between normal shooting and dedicated shooting taking advantage of the photographer's sensitivity.

  As such an example, there is image processing for enhancing or suppressing color and contrast.

  Also, there are effects such as spotlight hitting the center, and effects such as deforming the periphery, but these are not only performed by electrical image processing, but also by moving the aperture and optical system, It is also possible to obtain an effect.

  For example, it is possible to perform rotational movement about the optical axis of the photographic lens or shift movement in a direction parallel to the optical axis of the photographic lens, and special effects photographing can be performed by combining these movements.

  Also, moving from the central part to the peripheral part in the optical axis direction in order to switch between the first aberration mode for imaging with corrected aberrations and the second aberration mode for imaging with excessive spherical aberration. An aberration mode switching lens may be included.

  Further, an aberration mode switching system unit that controls movement of the aberration mode switching lens based on the shift movement of the ring member for switching between the first aberration mode and the second aberration mode may be provided. It is possible, and confirmation of the effect provision and photography can be performed quickly.

  Also, in the case of an optical system that has a device that can change the characteristics of the photographing lens itself, the operation can be simplified and easily understood by combining this shift operation.

  For example, the zoom lens may include a plurality of moving lenses that include an aperture stop and move for switching the focal length when focused at infinity. At this time, the focal length is changed by moving any of the plurality of moving lenses in conjunction with the rotational movement of the ring member, and the plurality of moving lenses in conjunction with the shift movement of the ring member. The zoom-single-focus switching system unit that performs switching to set a predetermined focal length by moving any of the above and the aperture size of the aperture stop to the maximum diameter so that zoom-single-focus switching can be performed. Good.

  Also, with this shift operation, it is possible to switch to a night vision mode suitable for shooting the starry sky, for example, when shooting with sensitivity switching, or backlight enhancement mode that increases the screen brightness when it is bright You may make it enter.

  Even when the photographic lens is designed to have a moving lens that moves to switch only two focal lengths when focused at infinity, the moving lens is moved in conjunction with the shift movement of the ring member. The operation method for switching the focal length is easy for the user to understand.

  Such alternative switching such as ON and OFF is preferable because the shifting operation of the lens unit operation ring (ring member) with a clear switching position and a small stroke does not miss the release timing and suppresses camera shake.

  When shooting is not performed, since the through image display is repeated, these controls and shooting can be performed at an arbitrary timing. When switching to the playback mode is performed, S102 is branched to S111, and the captured image is played back (S112).

  If the user wants to view another image, when the user again operates the touch panel or switch, it is determined in S113, and the image is switched in S115. Further, when neither the shooting mode nor the playback mode is set, in S114, a mode in which the operation can be set and changed by the operation ring of the lens is set.

  For this setting, a method is assumed in which a touch panel is used effectively, a menu is displayed on the touch panel, and the menu is selected.

  For example, the operation and the function may be associated with each other by the touch setting as illustrated in FIG. For example, an item that can be operated by rotation for each shift position of the ring member of the lens unit can be selected by the user setting the setting mode by a dial or touch operation (not shown).

  Further, the operation and control to be switched may be set by the shift operation itself. This figure shows how the user selects and sets from the icons.

  In the above embodiment, the example in which the rotation operation at two places is possible by the shift by the operation ring has been described. Of course, the operation ring can be rotated at three places as shown in FIG. Good. In this case, items that can be further operated are increased. With such a configuration, it is possible to perform control such that the normal focusing is performed at the first position, the zoom operation is performed at the second position, and the “super macro” mode is set at the third position.

  FIG. 6 shows, for example, a positive, negative, positive, and positive five-group zoom lens that is extended when four object lens groups arranged on the left side in the drawing are set to the telephoto side. Normal focusing of this type of lens is performed by the fourth lens group or the fifth lens group.

  With such a lens configuration, the movement of the lens in the “super macro” mode will be described.

  In such an optical system configuration, only the positive lens of the third lens group moved during zooming is moved from the normal position in FIG. 6A to the position in FIG. 6B, so that it is closer to the original focus position. It becomes possible to focus on the distance side.

  In this example, the third lens group is moved to the image side. However, the moving direction in which the super macro mode is set varies depending on the type and design of the zoom lens. In addition, a method in which the first lens unit moves to the object side in the macro mode may be used, but in this case, a feeding mechanism must be prepared for that purpose.

  Such control is called a “super macro” mode because a high magnification at the time of telephoto is ensured and a close-up subject can be focused, so that a close-up subject can be taken larger than normal shooting. For example, if such a mode is entered by the operation ring shift, which is a feature of the present invention, the user can hold the camera firmly so that the camera does not shake without unnecessary button operation, and immediately approaches. It is possible to shoot while focusing on a subject at a distance.

  In addition, by moving the lens from the normal position to a different position in this way, it is possible to change not only the focus position but also the image description characteristics. For example, the curvature of the image is corrected. For example, the second negative lens group from the left side of the lens in FIG. It can be described as flowing.

  FIG. 7 shows the effect of expressing the peripheral image by curving the image plane and flowing it radially with astigmatism while leaving the subject at the center of the screen as it is by controlling the position of the optical system. It is illustrated. These are assumed to be performed by the drive unit 24 and the position determination unit 25 in FIG. 1, but may be dealt with by performing a mechanical design interlocking with the shift of the operation ring.

  When the center dog is focused as shown in FIG. 7 (a) and the lens for correcting curvature of field is shifted by, for example, shifting the operation ring of the lens unit, the peripheral area as shown in FIG. 7 (b) is obtained. You can shoot images with In this way, after focusing and framing, a special effect photograph can be taken by a series of operations without changing the camera. The flow condition may be changed by changing the position of the field curvature correction lens by a rotation operation after the shift.

  The shift direction is not limited to the optical axis direction, and the effect of decentration aberration can be obtained by moving the shift direction perpendicular to the optical axis. Moreover, you may use together with a tilt movement.

  Up to now, the term “special image processing” or “filter” has been used to describe shooting that is different from normal shooting. However, shooting with an effect as shown in FIG. Of course, an image having the same effect can be taken by image processing. In this case as well, the same effect can be obtained by enhancing the peripheral image in the radial direction. Of course, an electrical treatment may be used in combination with an optical one.

  Here, an explanation has been given that a fixed effect can be obtained by the lens shift. However, filters such as color enhancement, contrast reduction processing, and local enhancement may be selected by subsequent rotation.

  In addition, the calculation for correcting the aberration may be changed to depict a fish-eye lens, or the aperture shape and position may be changed to depict a pinhole camera.

  Hereinafter, an example will be described in which the movement of the member by the shift operation of the operation ring of the lens unit and the force at that time are effectively used.

  In FIG. 8, the position of the focusing lens 26b is changed according to the shift position of the operation ring 23 (here, three stages (a), (b), and (c)). Thus, for example, if there is a shift operation, if the focusing lens is stopped at a position where a subject of 10 m, 2.5 m, or 1 m is focused, a long distance, a normal distance, and a short distance are instantaneously generated. Pan-focus shooting with emphasis on can be performed. This makes it possible to immediately shoot what is found when walking around the city. Of course, the focus may be finely adjusted by performing a rotation operation from this state. This is because the camera body control unit 1 and the lens control unit 21 change the position of the focusing lens with an actuator according to the operation, so that it is possible to cope with operation control with a high degree of freedom by a control program. Of course, a mechanical configuration may be adopted in which a lens other than the original focusing lens or the entire lens is extended by such a shift operation. Thus, a camera with a wide focus distance range can be provided.

  FIG. 9 shows an example of changing not only the focus position but also the aperture position.

  FIG. 9A shows a case where the diaphragm is stopped behind the middle optical system. Since the operation ring 23 is separated from the diaphragm member 26c, the diaphragm member is a negative member (not shown), and the diaphragm member is located on the rear side (camera body side). The aperture stops and blocks the optical path by narrowing the back side of the middle lens.

  However, if the operating ring 23 is pushed forward in the direction of the subject, the arm extending from the operating ring as shown in FIG. 9B pushes the projection 26c of the diaphragm member, so that the support shaft (denoted by ○) is used. The diaphragm member 26c falls to the front side (subject side) at the center, and forms a diaphragm on the front side of the middle lens to block the optical path.

  By switching the aperture position as described above, an ambient light shielding effect different from the effect of the original aperture is generated, and an image can be displayed such that the periphery of the screen becomes dark.

  The state shown in FIG. 9B is a normal stop, and the light beam is stopped between the two lenses, and there is an effect of suppressing the amount of light at a substantially parallel position. If the operation ring is rotated in this state, the narrowing may be changed.

  In the state shown in FIG. 9A, the diaphragm is opened in a state where the light beam spreads, and the surrounding light is kicked to allow shooting with a special effect.

  The aperture shape may be as shown in FIG. As the length of the arm portion of the operation ring 23 in FIG. 9 is changed by the rotation, the amount by which the diaphragm member 26c is tilted is changed (FIG. 10 (a) → (b)), as shown in FIG. 10 (c). If the light can be completely shielded, for example, it is possible to obtain an effect of blacking out during moving image shooting.

  Such aperture control is a mechanism or control that changes the aperture position in the direction of the optical axis in conjunction with the shift operation of the operating ring. Can be controlled, and an impressive image can be obtained that calls attention to the main subject in a spotlight manner.

  Here, it is simply described as “aperture control”, but this “aperture” includes a flare stop for suppressing the flare of the lens and a brightness stop for limiting including the axial light flux. In particular, by changing the flare stop, it is possible to control the luminous flux at the periphery of the lens to express the flare effect.

  FIG. 11 further explains that an operation different from normal photographing can be performed by such an operation ring. If the camera specification is such that movie shooting can be started and stopped by the release switch 6a as shown in FIG. 3, the lens unit is supported with the left hand and the camera is held so as not to shake. Still image shooting (still shooting) can be performed at the timing.

  That is, as shown in FIG. 11 (a), moving image shooting is performed while checking on the rear display unit, and if the operation ring shift of the lens unit is performed, a still image can be shot at that timing. FIG. 11A shows a state in which moving image shooting is continued on the main screen of the display unit 8, and a state in which a still image shot on the sub-screen (small screen) is displayed. By performing such display, it is possible to enjoy moving image shooting while confirming the shot still image. If still image shooting fails, you can retake it immediately.

  It is also possible to effectively perform the switching operation utilizing the characteristics of the lens type by shifting the operation ring (ring member).

  FIG. 12 illustrates an example of a bifocal switching lens, and FIG. 13 illustrates a photographing lens of a type that can switch a zoom lens between a low zooming type and a high zooming type. The anomalous lens group movement peculiar to such a type is effective for switching by a ring member shift operation, and can enjoy shooting with intuitive switching of the angle of view. By using a completely light-shielded aperture and image processing as shown in FIG. 10, the image at the time of switching can be blacked out or blurred to give a natural feeling of operation. Especially with movies, you can enjoy a good tempo of angle of view.

    The bifocal lens of FIG. 12 is focused by the fourth lens group (focus group) on the most image side (right side), and the sense of the second and third lens groups in the middle is changed as indicated by arrows. , Change the focal length. 12A is a retrofocus type and the angle of view is wide, and FIG. 12B is a telephoto type arrangement, so the focal length can be increased.

  Further, in the zoom lens with zooming switching shown in FIG. 13, focusing is performed with the fourth lens group (focus group) on the most image side (right side). The zoom lens becomes a low zoom ratio zoom lens with a small movable area of the lens group, and becomes a high zoom ratio zoom lens with a large movable area of the variable power lens group by increasing the total length of FIG. The range of focal length can be expanded. In conjunction with a slight shift operation of the ring operation unit, the first and second lens groups shift to the object side, the third lens group shifts to the image side, and the overall length becomes longer. Other than that, it can be made compact.

  For example, when a camera is used for shooting with low zoom ratio and small turning, when a bird suddenly enters the field of view and wants to take a big picture of a distant object, there is no camera shake without looking at the subject. Users can easily shift to shooting using the long focal point immediately. Continuous operation is important for video shooting and the like.

  In the previous examples, the rotation and shift of the lens unit operation ring was used for switching various shooting effects. A device that does not miss is also possible.

  In order to show that the gear portion attached to the operation ring can be engaged with the gear train inside the lens and transmit the movement by the operation ring shift in the configuration as shown in FIG. The state of the gear train 41 that moves the dynamo at high speed is shown by arrows.

  The gear train 41 may be configured to generate power by rotating a dynamo 42 or the like built in the lens unit. The current from the dynamo is rectified by the rectifier circuit 43 and output to the charging unit 44 for the battery 45 of the main body. This makes it possible to assist by recharging the operating ring when the battery energy is about to decrease.

  Except for this power supply unit, it is the same as that shown in FIG.

  In this way, by combining the rotation operation of the lens unit and the shift operation, when the battery runs out, power can be generated by rotating the operation ring, and it is possible to devise a technique to supplement the energy for camera control. You can charge the bag while aiming at the subject while holding the camera.

  As described above, the imaging apparatus described in the present invention is also characterized by being an “optical apparatus including a ring member that performs rotational movement and shift movement”. In the conventional photographing apparatuses, when a zoom lens is provided, a rotation operation ring member for zooming only and a rotation operation ring member for focusing only have been known. In order to switch the focusing operation, the operation ring had to be changed.

  The optical device according to claim 5 is the one described with reference to FIG. 7, and can quickly switch between normal shooting and special effect shooting, and can immediately give the user's favorite effect.

Thus, for example, in shooting around the city, it is possible to take a picture with a no finder in which the visual distance is set in advance and is immediately in focus.

  The optical device according to claim 7 is the one described with reference to FIGS. 9 and 10, and can quickly switch between shooting with normal light amount adjustment of the entire screen and shooting with different light amount adjustment around the screen, and the center of the screen. It is possible to perform impressive shooting that looks like a spot.

  The optical device according to claim 8 is the one described with reference to FIG. 10 and facilitates the operation of adjusting the brightness of the photographing lens.

  The optical device according to claim 9 is a modification of the one described with reference to FIGS. 9 and 10, and the photographing is performed by adjusting the light amount of the entire normal screen, and the light amount around the screen is reduced or the flare is increased. It is possible to switch easily and quickly to capture special effects such as obtaining a deteriorated image.

  The optical device according to the tenth aspect is the one described with reference to FIG. 15, and the operation unit is simplified to enable photographing of the eyelid at the time of power consumption by an operation that is easy for the user to understand. In a situation where the battery is likely to run out, the camera can be recharged immediately while holding the camera, so the display will not disappear or a photo opportunity will not be missed.

  The optical device according to the eleventh aspect is the one described in FIG. 11, and enables shooting without missing a photo opportunity in cooperation with the release button. I have to.

  The optical device according to the twelfth aspect is the one described in FIG. 3C, S106e in FIG. 4, FIG. 14, and the like. It becomes easy to take a picture while balancing the visibility and the noise image.

  The optical device according to claim 13 is the one described in S106e of FIG. 3 and FIG. 4, FIG. 14, and the like, and can enjoy various special effects by using the rotation operation, adjust the angle of view and focus, It is possible to shoot with image processing according to the photographer's preference in response to various scenes. For example, since the effect of the soft focus effect changes depending on the focus position and the subject depth by zooming, shooting by trial and error is important for shooting according to the user's image.

  The optical device according to claim 14 is a modification of the one described in FIG. 3C, S106e in FIG. 4, FIG. 14, and the like. The image conversion filter is quickly turned on and off, and a special image is immediately captured. It becomes possible to.

  The optical device according to the sixteenth aspect is switched by the operation described in FIG. 3C or S106e in FIG. 4, and does not set the entire range of the single zoom lens in the zoom range. Only the predetermined portion set in the setting mode of S114 may be used so that the usable focal length range can be limited to only the frequently used region. This can simplify the operation. As shown in FIG. 13, the zoom lens may be switched between the low zoom type and the high zoom type at the first shift position and the second shift position.

  The optical device according to claim 17 is the one described in S106e of FIG. 4 and the like, and can easily be switched to the optical soft focus effect.

  The optical device according to claim 18 is the one described in S106e of FIG. 4 and the like, and an operation such as switching between a zoom lens and a bright single focus lens can be easily performed. The predetermined focal length may be set in the vicinity of a state in which the imaging performance is the best when the aperture size of the aperture stop is the maximum diameter in the zooming range of the zoom lens.

  As described above, according to the present invention, the lens unit protruding forward toward the subject can be firmly held to concentrate on photographing and display confirmation, and the operation can be switched without shaking. In particular, during moving image shooting, it is important to switch while aiming at the subject and keeping track of it. Such an operation can be performed quickly and intuitively, and is essential for improving the completeness of the captured image.

  For example, when performing other operations such as adding a special effect filter (whether optical or electrical), it is necessary to operate a part different from the operation ring member once the subject is captured in the shooting area. Was common. Therefore, it has been difficult to quickly perform shooting with various effects.

  It is an object of the present invention to provide an optical device with improved operability by devising an operation ring member and a system interlocked therewith. Each above-mentioned invention can be constituted so that a plurality may be satisfied simultaneously. Further, it is possible to change the object to be controlled by the rotation of the ring member such as zooming, focusing, and a configuration that involves changing the aperture value.

However, the camera may be a digital single lens reflex camera or a compact digital camera, such as a video camera or a movie camera. A camera for moving images may be used, and a camera built in a mobile phone, a personal digital assistant (PDA), or the like may of course be used.

It doesn't mean. In addition, it goes without saying that the steps constituting these operation flows can be omitted as appropriate for portions that do not affect the essence of the invention.
