  The memory card 12 is an external memory provided with storage means such as a flash memory. The memory card 12 can store data such as image data processed by the camera controller 6. The memory card 12 can output data such as image data stored therein. The image data output from the memory card 12 is processed by the camera controller 6 and reproduced and displayed on the liquid crystal monitor 10 or the like, for example. In this embodiment, the memory card 12 is shown as an example of the external memory, but the present invention is not limited to this. For example, a storage medium such as an optical disk may be used as the external memory.

  The power supply 16 supplies power for consumption by the camera system 1. The power source 16 may be, for example, a dry battery or a rechargeable battery. Moreover, the power supplied from the outside by the power cord may be supplied to the camera system 1.

  The release button 13 is disposed on the upper part of the camera body 2. The user can execute an operation such as still image shooting by pressing the release button 13.

  The OIS lens 24 is a lens for correcting blurring of a subject image formed by the optical system of the interchangeable lens 31. Any number or group of OIS lenses may be used. The OIS lens 24 moves in a direction that cancels out the blur of the camera system 1, thereby reducing the blur of the subject image on the CCD image sensor 3. The OIS lens 24 is moved by the operation of the OIS driving unit 25 based on the detection result of a shake detector such as a gyro sensor. The OIS drive unit 25 obtains the detection result of the shake detector from the lens controller 23. Further, the OIS drive unit 25 transmits a signal indicating the state of the optical image blur correction process to the lens controller 23. A signal indicating the state of the optical image blur correction process received by the lens controller 23 is transmitted to the camera controller 6 via the lens mount 18.

  The focus lens 27 is a lens for changing the focus state of a subject image that is incident from the optical system and formed on the CCD image sensor 3. The lens configuration of the focus lens may be any number or group. The focus lens drive unit 28 drives the focus lens 27 to advance and retreat along the optical axis of the optical system based on the control of the lens controller 23. The focus ring 26 is provided on the exterior of the interchangeable lens 31. The focus ring 26 drives the focus lens 27 according to the user's operation. When the focus ring 27 is operated by the user, a signal related to the operation is output to the lens controller 23. The lens controller 23 drives the focus lens driving unit in accordance with the input operation-related signal.

  The lens controller 23 controls the entire interchangeable lens 31. The lens controller 23 may be configured with a hard-wired electronic circuit or a microcomputer using a program.

[1-5. Correspondence with the present invention)
The CCD image sensor 3 is an example of the imaging means of the present invention. The liquid crystal monitor 10 is an example of the display means of the present invention. The configuration including the left key of the cross button 45 and the camera controller 6 is an example of the enlargement instruction receiving means of the present invention. The configuration comprising the camera mount 17 and the camera controller 6 is an example of the information acquisition means of the present invention. The camera controller 6 is an example of the display control means of the present invention.

[2. Operation)
[2-1. (Image preparation operation)
First, the operation of the camera system 1 for preparation for imaging will be described. FIG. 3 is a diagram illustrating signal transmission / reception for explaining the imaging preparation operation of the camera system 1.

  When the user turns on the camera body 2 with the interchangeable lens 31 attached to the camera body 2, the power supply 16 supplies power to the interchangeable lens 31 via the body mount 17 and the lens mount 18 ( S11). Next, the camera controller 6 requests authentication information of the interchangeable lens 31 from the lens controller 23 (S12). Here, the authentication information of the interchangeable lens 31 includes information regarding whether or not the interchangeable lens 31 is mounted and information regarding whether or not an accessory is mounted. The lens controller 23 responds to the lens authentication request from the camera controller 6 (S13).

  Next, the camera controller 6 requests the lens controller 23 to perform an initialization operation (S14). In response to this, the lens controller 23 performs initialization operations such as resetting the aperture and resetting the OIS lens 24. Then, the lens controller 23 returns to the camera controller 6 that the lens initialization operation has been completed (S15).

  Next, the camera controller 6 requests lens data from the lens controller 23 (S16). The lens data is stored in the flash memory 30. Therefore, the lens controller 23 reads the lens data from the flash memory 30 and sends it back to the camera controller 140 (S17). Here, the lens data is a characteristic value unique to the interchangeable lens 31 such as a lens name, an F number, and a focal length.

  When the camera controller 6 grasps the lens data of the interchangeable lens 31 attached to the camera body 2, the camera controller 6 is ready for imaging. In this state, the camera controller 6 periodically requests lens state data indicating the state of the interchangeable lens 31 from the lens controller 23 (S18). The lens state data includes, for example, zoom magnification information by the zoom lens 20, position information of the focus lens 27, aperture value information, and the like. In response to this request, the lens controller 23 returns the requested lens state data to the camera controller 6 (S19).

  In this state, the camera system 1 can operate in a control mode in which an image indicated by image data generated by the CCD image sensor 3 is displayed on the liquid crystal monitor 10 as a through image. This control mode is called live view mode. In the live view mode, the through image is displayed as a moving image on the liquid crystal monitor 10, so that the user can determine the composition for capturing a still image while viewing the liquid crystal monitor 10. The user can select whether to use the live view mode. In addition to the live view mode, another control mode that can be selected by the user is a control mode that guides the subject image from the interchangeable lens 31 to the electronic viewfinder (EVF). A contrast method is suitable as a method of autofocus operation in the live view mode. This is because in the live view mode, the image data is constantly generated by the CCD image sensor 3, so that the contrast-type autofocus operation using the image data is easy.

  When performing the contrast-type autofocus operation, the camera controller 6 requests contrast AF data from the lens controller 23 (S20). The contrast AF data is necessary for the contrast autofocus operation, and includes, for example, a focus drive speed, a focus shift amount, an image magnification, and contrast AF availability information.

[2-2. (Manual assist operation)
The manual assist operation is an operation for displaying an enlarged image of the focus area on the liquid crystal monitor 10 so that the user can easily confirm the focus state of the subject image during manual focus. Hereinafter, the manual assist operation of the camera system 1 according to the first embodiment of the present invention will be described in detail with reference to the flowchart shown in FIG.

  When the user sets the camera system 1 to perform a manual assist operation, the camera system 1 performs the operation of the present invention. As described above, the camera controller 6 provided in the camera body 2 and the lens controller 23 provided in the interchangeable lens 31 communicate with each other via the body mount 17 and the lens mount 18. When the operation of the camera body 2 is set to the manual focus mode, the camera controller 6 grasps in advance whether the lens controller 23 can output information related to the operation of the focus ring 26 provided in the interchangeable lens 31 to the camera controller 6. Keep it.

  When the focus ring 26 is operated (S31) and when the camera controller 6 can acquire information related to the operation of the focus ring 26 (S32), the camera controller 6 monitors whether the focus ring 26 is operated. Then, in response to the operation of the focus ring 26, the liquid crystal monitor 10 is controlled to zoom up and display an image near the focus area (S33).

  FIG. 6 shows an image of zoom-up display. The frame D1 is a normal image display, the dotted frame D2 is a focus area, and the frame D3 is a zoom-up image display. The user can move the focus area D2 within the display of the liquid crystal monitor 10 by operating the cross button 45 during normal image display and zoom-in image display. While the camera controller 6 accepts the operation of the cross button 45 by the user, the camera controller 6 controls the liquid crystal monitor 10 so as to continue displaying the zoomed-up image.

  In addition, when the front dial 14 is operated during zoom-up display, the camera controller 6 changes the zoom-up display magnification of the focus area.

  Furthermore, the liquid crystal monitor 10 displays information representing the positional relationship between the zoomed-up image area and the original image. A frame D4 in FIG. 6 represents an original image, and a dotted frame D5 represents an image area that is zoomed up.

  When the release button 13 is pressed halfway during zoom-up display (S34), the camera controller 6 controls the liquid crystal monitor 10 to restore the image and end the zoom-up display (S36). In addition, even when the release button 13 is not pressed halfway during zoom-up display, the camera controller 6 returns the image to the original zoom after a predetermined time has elapsed (S35). The liquid crystal monitor 10 is controlled to end the up display (S36).

  As a result, when the image near the focus area is zoomed up once, but the user does not perform the manual focus operation for a certain period of time, the liquid crystal monitor 10 ends the zoom up display and returns to the original image display. Therefore, the user does not have to perform the enlargement display canceling operation by waiting for a predetermined time. When the user performs the next shooting operation, the display on the liquid crystal monitor 10 returns to the original image display, so that the user can quickly perform the next shooting.

  On the other hand, when the focus ring 26 is operated and the camera controller 6 cannot acquire information related to the operation of the focus ring 26 (S32), the camera controller 6 detects even if the focus ring 26 is operated. Since the image cannot be enlarged, the image displayed on the liquid crystal monitor 10 cannot be enlarged.

[2-3. Zoom-up display operation by camera body operation)
The zoom-up display operation by the operation on the camera body 2 side will be described with reference to FIG. When the manual assist operation mode is set and the left key of the cross button 45 is pressed in the imaging mode (S41), the camera controller 6 does not depend on the type of interchangeable lens mounted. The liquid crystal monitor 10 is controlled to enlarge the currently displayed image (S33). The zoom-up display operation at this time is the same as the zoom-up display operation performed in response to the operation of the focus ring 26 described above.

  In this case, the camera controller 6 does not cancel the zoom-up display operation until the release button 13 or the determination button 44 is pressed even after a predetermined time has elapsed (S34).

  Thus, even when an interchangeable lens that does not transmit information related to the operation of the focus ring is attached, the zoom-up display operation can be started by the user's operation. Furthermore, even after a predetermined time has passed, the zoom-up display operation is not canceled unless the zoom-up display operation is canceled based on the user's will, so the zoom-up display operation can be performed even when the focus ring is being operated. It can be prevented from being terminated.

  As with the zoom-up operation according to the focus ring operation, if the zoom-up operation is automatically terminated after a predetermined time has elapsed since the zoom-up operation started, the focus ring is being operated. There may occur a situation in which the zoom-up display operation ends. If such a situation occurs, the usability will be poor.

[3. (Summary)
As described above, the camera body 2 according to the first embodiment of the present invention can output information indicating that the focus ring for changing the focus state of the subject image formed by the optical system is operated. The interchangeable lens and the camera body 2 in which the second interchangeable lens that does not output information indicating that the focus ring has been operated can be selectively attached and detached. The camera body 2 includes a CCD image sensor 3, a liquid crystal monitor 10, a left key of a cross button 45, a camera controller 6, and a camera mount 17. The CCD image sensor 3 captures a subject image formed by the first interchangeable lens or the second interchangeable lens with the first interchangeable lens or the second interchangeable lens attached, and generates image data. The liquid crystal monitor 10 displays an image based on the generated image data. The configuration including the left key of the cross button 45 and the camera controller 6 accepts an image enlargement instruction for enlarging and displaying an image based on the generated image data. The configuration including the camera mount 17 and the camera controller 6 obtains information indicating that the focus ring has been operated from the first interchangeable lens in a state where the first interchangeable lens is mounted. When the camera controller 6 acquires information indicating that the focus ring has been operated in a state where the first interchangeable lens is mounted, until the predetermined time elapses from the acquisition of the information. The liquid crystal monitor 10 is controlled so that the image is enlarged and displayed, and after returning to the original size after a predetermined time has elapsed. On the other hand, when the camera controller 6 receives an image enlargement instruction via the left key of the cross button 45, the camera controller 6 controls the liquid crystal monitor 10 to continuously enlarge and display the image until the instruction is canceled.

  As described above, when the display image is enlarged according to the operation on the focus ring on the interchangeable lens side, the enlarged image display operation is canceled after a predetermined time has elapsed. On the other hand, when the display image is enlarged in accordance with the operation on the camera body side, the cancellation of the enlarged image display operation over time is not executed.

  Accordingly, when an interchangeable lens that transmits information related to the operation of the focus ring is attached, the enlarged image display operation can be automatically canceled, so that the operability is good. In addition, even when an interchangeable lens that does not transmit information related to the operation of the focus ring is attached, an enlarged image display operation can be performed, and an enlarged image display operation can be performed against the user's will during the focus ring operation. It can be prevented from being released.

  For this reason, even with the interchangeable lens system, it is possible to focus more accurately by manual focus operation, and it is possible to improve usability.

[Other Embodiments]
In the first embodiment of the present invention, the configuration having the zoom lens 20 and the OIS lens 24 is exemplified, but these are not essential configurations of the present invention. Similarly, the present invention is also applicable to a camera system equipped with an interchangeable lens that does not have a blur correction function.

  In the first embodiment of the present invention, the camera body that does not include the movable mirror is illustrated, but the present invention is not limited to this. For example, a movable mirror may be provided in the camera body, or a prism for separating the subject image may be provided. Moreover, the structure provided with a movable mirror not in the camera body but in the adapter may be used.

  In Embodiment 1 of the present invention, when the camera controller 6 receives an image enlargement instruction on the camera body 2 side, the currently displayed image is enlarged regardless of the type of the interchangeable lens attached. The liquid crystal monitor 10 was controlled. However, the present invention is not limited to this. For example, when the camera controller 6 receives an image enlargement instruction on the camera body 2 side, it is currently displayed only when the attached interchangeable lens is an interchangeable lens that does not transmit information regarding the operation of the focus ring. The liquid crystal monitor 10 may be controlled to enlarge the image. In this case, when the interchangeable lens that is mounted is an interchangeable lens that transmits information related to the operation of the focus ring, it is preferable to invalidate the instruction even if an image enlargement instruction is given on the camera body 2 side. . As a result, when an interchangeable lens that transmits information related to the operation of the focus ring is attached, the manual assist function operates only when the manual focus operation is performed, so that the user is confused about the operation. Can be prevented.

  In Embodiment 1 of the present invention, the zoom-up display operation is started in response to the left key of the cross button 45 being pressed. However, the present invention is not limited to this. For example, the zoom-up display operation may be started according to the detection result of the voice sensor or the touch sensor. In short, the zoom-up display operation may be started according to the operation on the camera body 2 side.

  In Embodiment 1 of the present invention, the zoom-up operation is canceled by pressing the release button 13, but the present invention is not limited to this. For example, the zoom-up operation may be canceled when the cross button 45 or the display button 43 is pressed. In short, the zoom-up operation may be canceled at the user's will.

  The present invention is not limited to a digital camera. For example, the present invention can be applied to any device that captures images, such as a digital movie camera or a mobile phone with a camera function. In short, the present invention can be applied to any imaging device with interchangeable lenses.
