Further, the mirror 12 is a half mirror so that the central portion thereof can transmit a part of the light, and a part of the light flux is transmitted so as to be incident on the focus detection unit 11 for performing the focus detection.

By observing the image formed on the focusing screen 13 via the pentaprism 14 and the finder 16, the photographer can confirm the focal state and composition of the optical image of the subject obtained through the lens unit 150. ..

The shutter 101 is for controlling the exposure time of the imaging unit 22 under the control of the system control unit 50.

The image pickup unit 22 is an image pickup device composed of a CCD, a CMOS element, or the like that converts an optical image into an electric signal. The A / D converter 23 converts an analog signal into a digital signal. The A / D converter 23 is used to convert an analog signal output from the image pickup unit 22 into a digital signal.

The image processing unit 24 performs resizing processing such as predetermined pixel interpolation and reduction and color conversion processing on the data from the A / D converter 23 or the data from the memory control unit 15. Further, in the image processing unit 24, a predetermined calculation process is performed using the captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the obtained calculation result. As a result, TTL (through-the-lens) AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-flash) processing are performed. Further, the image processing unit 24 performs a predetermined calculation process using the captured image data, and also performs a TTL method AWB (auto white balance) process based on the obtained calculation result.

The output data from the A / D converter 23 is written directly to the memory 32 via the image processing unit 24 and the memory control unit 15 or via the memory control unit 15. The memory 32 stores image data obtained by the image pickup unit 22 and converted into digital data by the A / D converter 23, and image data to be displayed on the display unit 28. The memory 32 has a storage capacity sufficient for storing a predetermined number of still images, moving images for a predetermined time, and audio. Further, the memory 32 also serves as a memory (video memory) for displaying an image. The D / A converter 19 converts the image display data stored in the memory 32 into an analog signal and supplies it to the display unit 28.

The modes included in the still image recording mode include an auto shooting mode, an auto scene discrimination mode, a manual mode, an aperture priority mode (Av mode), and a shutter speed priority mode (Tv mode). In addition, there are various scene modes, program AE modes, custom modes, etc. that are shooting settings for each shooting scene. The mode changeover switch 60 directly switches to any of these modes included in the menu screen. Alternatively, after switching to the menu screen once with the mode changeover switch 60, the mode may be switched to any of these modes included in the menu screen by using another operation member. Similarly, the moving image shooting mode may include a plurality of modes.

The first shutter switch 62 is turned on by a so-called half-pressing (shooting preparation instruction) during the operation of the shutter button 61 provided on the digital camera 100, and the first shutter switch signal SW1 is generated. The first shutter switch signal SW1 starts operations such as AF (autofocus) processing, AE (autoexposure) processing, AWB (auto white balance) processing, and EF (flash pre-flash) processing.

The second shutter switch 64 is turned on when the operation of the shutter button 61 is completed, that is, when the shutter button 61 is fully pressed (shooting instruction), and the second shutter switch signal SW2 is generated. The system control unit 50 starts a series of shooting processing operations from reading the signal from the image pickup unit 22 to writing the image data to the recording medium 199 by the second shutter switch signal SW2.

Each operation member of the operation unit 70 is assigned a function as appropriate for each scene by selecting and operating various function icons displayed on the display unit 28, and acts as various function buttons. Examples of the function button include an end button, a back button, an image feed button, a jump button, a narrowing down button, an attribute change button, and the like. For example, when the menu button is pressed, various configurable menu screens are displayed on the display unit 28. The user can intuitively make various settings by using the menu screen displayed on the display unit 28 and the up / down / left / right four-direction buttons and the SET button. The operation unit 70 is various operation members as an input unit that receives an operation from the user.

The power supply control unit 80 includes a battery detection circuit, a DC-DC converter, a switch circuit for switching a block to be energized, and the like, and detects whether or not a battery is installed, the type of battery, and the remaining battery level. Further, the power supply control unit 80 controls the DC-DC converter based on the detection result and the instruction of the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 199 for a necessary period.

The communication unit 54 can transmit an image (including a through image) captured by the image pickup unit 22 and an image recorded on the recording medium 199, and can also receive image data and other various information from an external device. can.

The external I / F 55 can acquire information regarding the type (ID) of the connected lens and whether or not the adapter is connected. The lens can be directly connected to the external I / F 55, or the lens can be connected via an adapter.

3A to 3C show a lens unit 150 and an adapter 200 that can be connected to the digital camera 100 shown in FIG. A block diagram is shown on the upper side of each figure, and an external view of the rotating member is shown on the lower side. The zoom ring and focus ring described later are arranged along the outer circumference of the lens unit 150, and the operation ring described later is arranged along the outer circumference of the adapter. The operation ring 202 of the adapter 200 is a rotating member that can rotate along the circumference of the lens barrel.

FIG. 3A shows a single focus lens as an example of the lens unit 150. Single focus lenses include wide-angle lenses, standard lenses, and telephoto lenses. The lens 103 is usually composed of a plurality of lenses, but here, only one lens is shown for brevity. The communication terminal 6 is a communication terminal for the lens unit 150 to communicate with the digital camera 100 side (also possible via the adapter 200). The lens unit 150 communicates with the system control unit 50 via the communication terminals 6 and 10, controls the aperture 102 via the aperture drive circuit 2 by the internal lens system control circuit 4, and controls the aperture 102 via the AF drive circuit 3. Then, the focus is adjusted by shifting the position of the lens 103. The focus ring 7 is a ring operation member for adjusting the focus, and the presence / absence of rotation and the amount of rotation are detected by the focus ring rotation detection unit 7a capable of detecting the rotation of the focus ring 7, via the lens system control circuit 4. The lens 103 is controlled.

FIG. 3B shows a zoom lens as an example of the lens unit 150. The configuration of the zoom lens is the configuration of the single focus lens shown in FIG. 3A with the addition of a zoom function. The zoom lens zooms in or out according to the rotation operation to the zoom ring 8. The zoom ring 8 is a ring operation member for adjusting the zoom, and the presence / absence of rotation and the amount of rotation are detected by the zoom ring rotation detection unit 8a capable of detecting the rotation of the zoom ring 8, via the lens system control circuit 4. The zoom lens 104 is controlled.

FIG. 3 (c) shows the adapter 200. The adapter 200 is an operating member that can be mounted between the lens unit 150 and the digital camera 100 via a mount. The adapter 200 has an operation ring 202 which is a rotating member, and a function to be executed according to the rotation of the operation ring 202 can be set. For example, the setting values such as the shutter speed and the ISO sensitivity can be changed according to the rotation of the operation ring 202. The external I / F 201 is an I / F capable of communicating with the external I / F 55 of the digital camera 100 and the communication terminal 6 of the lens unit 150. The operation ring rotation detection unit 202a that can detect the rotation of the operation ring 202 detects the presence or absence of rotation and the amount of rotation, and information on the operation of the operation ring to the digital camera 100 side via the system control unit 203 and the external I / F 201. To communicate.

Next, the photographing process in the present embodiment will be described with reference to FIG. This process is realized by expanding the program recorded in the non-volatile memory 56 to the system memory 52 and executing the program by the system control unit 50. This process starts when the digital camera 100 is turned on and shooting becomes possible.

In S401, the system control unit 50 determines whether or not the lens is attached. When the external I / F 55 detects that the lens unit 150 is directly attached to the digital camera 100 or is attached via the adapter 200, the determination of S401 is Yes. If it is determined that the lens is attached, the process proceeds to S402, and if not, the process proceeds to S418.

In S402, the system control unit 50 acquires the ID (lens information) of the mounted lens unit 150. From the ID of the lens, the type of lens (zoom lens or single focus lens, telephoto lens, standard lens, wide-angle lens, etc.) and individual information of each lens can be known.

In S403, the system control unit 50 determines whether or not the operation ring 202 (adapter 200) is attached. If it is determined that the operation ring 202 is attached, the process proceeds to S404, and if not, the process proceeds to S418.

In S404, the system control unit 50 determines whether or not an operation for setting a function assigned to the operation ring 202 has been performed. When assigning a function to the operation ring 202, it can be set by selecting an item related to the lens on the menu screen. The operation ring 202 can be assigned a function of changing setting values of items related to shooting such as shutter speed (Tv), aperture (Av), ISO sensitivity, white balance, and switching of shooting modes. Since the operation member is located near the lens unit 150, the user can change the setting of the set item by rotating the operation ring 202 without having to bother to change the camera while holding the camera. If it is determined that the operation for setting the function to be assigned to the operation ring 202 has been performed, the process proceeds to S405, and if not, the process proceeds to S406.

In S405, the system control unit 50 records the set function in the non-volatile memory 56 in correspondence with the ID of the currently mounted lens unit 150. In this way, it is possible to set the function assigned to the operation ring 202 for each lens unit 150 mounted.

In S406, the system control unit 50 determines whether or not the function of the operation ring corresponding to the ID of the lens acquired in S402 is set. That is, whether or not the function assigned to the operation ring is set when the currently mounted lens is mounted is acquired by looking at the information in the non-volatile memory 56. If the function assigned to the operation ring when the currently mounted lens is mounted is set by the user, the process proceeds to S407, and if not, the process proceeds to S408.

In S407, the system control unit 50 records the function assigned to the operation ring 202 in the system memory 52. By recording in the system memory 52, the system control unit 50 can control the execution of the function according to the rotation amount of the operation ring 202. For example, when the ISO sensitivity setting change is assigned, the ISO sensitivity is changed according to the rotation amount of the operation ring 202.

S408 to S414 are processes for newly assigning a function to the operation ring 202 when the function to be assigned to the operation ring 202 has not yet been set by the user in the current lens. However, here, the assigned function is different from the setting on the menu screen, and is deleted (not recorded in the non-volatile memory 56 but recorded in the system memory 52) according to the power OFF of the digital camera 100. May be good.

In S408, the system control unit 50 determines whether or not the currently mounted lens is a telephoto lens. 5 (a) to 5 (e) are views showing the relationship between the operation ring 202 of the adapter 200 and each ring (focus ring 7 and zoom ring 8) of the lens unit 150. FIGS. 5 (a) to 5 (c). ) Indicates a single focus lens, and (d) and (e) indicate a zoom lens. In S408, it is determined to be Yes when the telephoto lens shown in FIG. 5 (c) or (e) is attached. If it is determined that the lens is a telephoto lens, the process proceeds to S409, and if not, the process proceeds to S410. Judgment is made based on whether or not.

In S409, the system control unit 50 allocates a change in the set value of the Tv value as a function of the operation ring 202 and records it in the system memory 52. In addition, since it is considered that there are many cases where a moving subject is photographed with a telephoto lens, if a function for changing the Tv value is assigned to the operation ring 202, the user can shoot without setting on the menu screen. .. Further, when a telephoto lens is used, the effect of blurring is likely to be applied in the first place, so there is a high possibility that the effect of blurring desired by the user can be obtained without changing the Av value as much as the standard lens. Further, in the case of a telephoto lens, the range of the Av value that can be set is narrowed, so that the operation ring 202 at a position that is easy to operate can be effectively utilized if the set value of the Tv value can be changed.

In S410, the system control unit 50 determines whether or not the currently mounted lens is a zoom lens. If it is determined that the standard zoom lens shown in (d) is attached among the zoom lenses shown in FIGS. 5 (d) and 5 (e), the determination of S410 is Yes. In the standard zoom lens, since there are two lenses, a zoom ring and a focus ring, in the lens unit 150, they are arranged so that the distance between them is as far as possible so as not to unintentionally operate the other ring at the time of each operation. There is. That is, the zoom ring and the focus ring are arranged at positions close to the end of the ring. On the other hand, in the case of a telephoto zoom lens, the distance of the lens is longer than that of a standard zoom lens, so even if the distance between the zoom ring and the focus ring is sufficient, each ring is located closer to the edge than the standard zoom lens. Not placed. When the adapter is attached, in the standard zoom lens, the distance between the operation ring 202 of the adapter 200 and the zoom ring located near the end of the lens unit 150 on the camera side becomes close. Therefore, the user may unintentionally rotate the operation ring 202 when operating the zoom ring, or conversely, rotate the zoom ring when the operation ring 202 is rotated. Therefore, when the determination of S408 is No and the determination of S410 is Yes, that is, when the mounted lens is a standard zoom lens, it is confirmed in S411 whether the function may be assigned to the operation ring 202. If it is determined that the lens is a zoom lens, the process proceeds to S411, and if not, the process proceeds to S412.

In S411, the system control unit 50 displays on the display unit 28 a guide as to whether or not to assign the change of the set value of the Av value to the operation ring 202. In S411, as shown in FIG. 6A, the display unit 28 displays a guide 601 indicating whether or not the operation ring may be assigned to change the setting of the Av value.

In S412, the system control unit 50 determines whether or not the operation ring 202 is assigned to change the set value of the Av value. The item 602 indicating OK is displayed together with the guide 601 shown in FIG. 6A, and by selecting the item 602, the function of the operation ring 202 is set to change the set value of the Av value. Further, the item 603 indicating the change for changing the function assigned to the operation ring 202 together with the guide 601 from the change of the Av value to another function is displayed. When the item 603 is selected, the determination of S412 becomes No. If it is determined that the change of the Av value setting value is assigned to the operation ring 202 (OK is selected), the process proceeds to S413, and if not, the process proceeds to S414 (change is selected).

In S413, the system control unit 50 allocates a change in the set value of the Tv value as a function of the operation ring 202, and records it in the system memory 52. When using a wide-angle, standard lens, it is often the case that a still life is taken, and there is a high possibility that the composition will be decided while changing the depth of field. Therefore, if the Av value setting change is assigned to the operation ring 202, the user can take a picture without setting on the menu screen.

In S414, the system control unit 50 displays the setting screen of the operation ring allocation function on the display unit 28. In S414, as shown in FIG. 6B, items 604 to 607 are displayed on the setting screen, and the user can set the function to be assigned to the operation ring 202 by selecting each item. .. Item 604 indicates a Tv value, item 605 indicates an ISO sensitivity, item 606 indicates WB (white balance), and item 607 does not indicate (no function is set). Also, if you select item 608, you can return to the screen where the original guide 601 is displayed. On the setting screen, the function corresponding to the item selected by the user is set in S407. When the function is set in S414, the function is recorded in the non-volatile memory 56 in association with the ID of the lens unit 150.

In S415, the system control unit 50 determines whether or not the operation on the operation ring 202 has been accepted. In S415, information on whether or not the operation ring 202 has been operated via the external I / F 55 is acquired and a determination is made. If it is determined that the operation to the operation ring 202 has been accepted, the process proceeds to S416, and if not, the process proceeds to S418.

In S416, the system control unit 50 acquires the operation amount of the operation ring 202.

In S417, the system control unit 50 executes the function recorded in the system memory 52 according to the operation amount acquired in S416.

In S418, the system control unit 50 determines whether or not a shooting instruction has been given by pressing the shutter button 61. If it is determined that the shooting instruction has been given, the process proceeds to S419, and if not, the process proceeds to S420.

In S419, the system control unit 50 performs a shooting process. When the set value is changed by the operation ring 202, shooting is performed at the set value whose setting has been changed. In the shooting process, the captured image acquired by the imaging unit 22 is recorded on the recording medium 199.

In S420, the system control unit 50 determines whether or not to end the shooting process. When the power of the digital camera 100 is turned off, the shooting process ends. If it is determined that the shooting process is finished, the shooting process is finished, and if not, the process returns to S401.

According to the above-described embodiment, the operation ring near the lens portion can be operated with good operability regardless of the type of lens to be mounted. In the case of a telephoto lens, the Tv value setting change is assigned to the operation ring, and in the case of a standard lens and wide-angle lens, the Av value setting change is assigned to the operation ring. Can be used without setting. In addition, since the operation ring 202 is located near the lens unit 150 and is easy to operate while holding the camera, the setting can be changed quickly by assigning a function that is likely to change the setting at the time of shooting, and the user's operability. Is improved.

Further, when the ring on the lens unit 150 side and the operation ring 202 are close to each other as in the standard zoom, the user is asked to confirm without setting the function on the camera side. At this time, it may be displayed that the operation ring 202 and the zoom ring are close to each other.

For the standard lens, the Av value is set in the case of a single focus, and in the case of a zoom lens, the Av value is not set, but a guide for confirming whether the Av value can be set is displayed on the confirmation screen. When the user sets the function to be assigned to the operation ring 202 on the menu screen, it is necessary to consider which function is assigned to which type of lens. As in the present embodiment, when the camera side sets the Av value setting change or displays the guide display and presents the Av value setting change, the user attaches the standard lens without having to think about the setting on the menu screen. You just have to select the function presented on the confirmation screen.

In the menu screen, the functions may be set for each of the telephoto lens, the standard lens, and the wide-angle lens, even if the settings are not set for each ID. However, when the standard zoom lens is attached, if the processes of S411 to S414 are performed, the possibility that the set value is unintentionally changed is reduced.

Further, whether the lens is a wide-angle lens, a standard lens, or a wide-angle lens may be determined by setting a threshold value. For example, the wide angle may be 30 mm or less, the standard may be 30 mm to 200 mm, and the telephoto may be 200 mm or more.

Further, the present embodiment can be applied even when the lens unit 150 and the adapter 200 are integrally provided. Further, the operation ring 202 may be in a position where it can be operated while holding the grip portion 90 such as the front of the digital camera 100 near the lens portion 150, even if it is not between the lens portion 150 and the digital camera 100.

The focus ring may be an electronic type or a method in which the lens mechanically moves according to the rotation of the ring.

Further, the function of the operation ring 202 may be set for the mounted lens, or may be set regardless of the mounted lens. However, when using a standard zoom lens, a confirmation screen is displayed. The function setting of the operation ring 202 may be cleared for the attached lens or for all lenses. Further, the rotation direction of the operation ring 202 and the content of function execution (direction of increase / decrease of the set value) may be set, but this setting is common to all lenses.

If the communication between the camera side and the lens side cannot be performed normally and the lens ID cannot be acquired, either the Tv or Av setting change is set as a function.

Further, when the function of the operation ring 202 is already set, if the function being set is displayed on the display unit 28 when the lens is attached, the user does not have to remember which function is set smoothly. You can perform operations. Furthermore, when setting the Av value or Tv value on the camera side, displaying a guide indicating that the Av value (Tv value) has been set as a function of the operation ring is effective because it can be recognized that the function has been set. Is. Furthermore, since it is understood that the setting operation on the menu screen does not have to be performed, it is not necessary for the user to consider which function is set or whether the setting operation must be performed.

Further, the recommended function assigned to the operation ring may be recorded on the lens side, and the function may be set according to the information from the lens side acquired by the digital camera 100.

In the above-described embodiment, it has been described that the function of changing the setting of the Tv value and the function of changing the setting of the Av value are set according to the type of the lens, but different functions are provided depending on the shooting mode. You may assign it. That is, even when the telephoto lens is attached, the Av value setting change is assigned in the Av mode, and even when the standard lens is attached, the Tv value setting change is made in the Tv mode. May be assigned.

It should be noted that the above-mentioned various controls described as those performed by the system control unit 50 may be performed by one hardware, or the entire device may be controlled by sharing the processing by a plurality of hardware. ..
