  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. A device according to the first embodiment to which the present invention is applied will be described with reference to FIGS. 1 and 2. This device has an operation unit, and can notify the operation state of the operation unit when there is a movement corresponding to the use situation.

  Various devices are provided with operation units for switching various modes and adjustment numerical values. Some modes can be switched discontinuously (digital), and others can be switched continuously (analog) like adjustment values. For example, if the camera has a precise target value such as the shooting mode, aperture, shutter speed, and various parameter settings, or if it is difficult to understand the effect of a small change, it is more convenient to switch digitally than analog. It is. On the other hand, for example, if the effect changes slightly due to subtle changes such as focusing and zooming operations (including optical and electrical) and setting of the designated area for shooting, etc., according to the user's preference For adjustment, it is more convenient to switch analogly than digitally.

  In many devices, by providing various switches, dials, lever operation members, etc. according to each application, the user can perform a switching operation suitable for the application. However, if a different operation member is provided for each adjustment target, the device becomes large in size, expensive, or accompanied by numerical display, which imposes various restrictions on the design, such as loss of versatility. Furthermore, there are cases where the user is confused before the operation. Therefore, in the present embodiment, the same input operation member has a plurality of functions. Such switching of a plurality of functions is performed only by a ring operation without intervening other operations such as a special switching operation and mode setting.

  FIG. 1 is a functional block diagram of a device according to the present embodiment. The device 100 includes a control unit 101, an operation unit 113, a notification unit 114, and a situation determination unit 115.

  The operation unit 113 is an operation unit for inputting a mode and an adjustment numerical value by a user operation, and is, for example, a ring-shaped operation unit. In the case of the ring-shaped operation unit, the rotation amount (including the rotation direction) is detected, and an operation signal corresponding to the rotation direction / rotation amount is output to the operation determination unit 103. If it is a slide operation member, the movement amount (including the movement direction) is detected, and an operation signal corresponding to the movement direction / movement amount is output to the operation determination unit 103. In addition to this, various operation members such as a joystick and a rotating ball can be used as the operation member. Note that the ring-shaped operation unit may have a click feeling, but in this embodiment, the click feeling may be fine, but there is no click feeling that does not require a click member in particular. Is assumed to be used.

  The operation unit 113 functions as a ring-shaped operation unit that can perform a uniform operation with respect to the center of rotation. It also functions as a ring-shaped operation unit that can be rotated with respect to the rotation center. However, there are various operations that the user wants to perform depending on the situation, and there are various cases, such as when the adjustment value is to be changed greatly immediately or when the adjustment effect is confirmed slowly and slowly. In addition, assuming such scenes where it is not easy to easily change the adjusted value, a ring operation member that does not have a feeling of operation or is monotonous during a rotating operation is not acceptable for the user. If you supplement it with information (notification) other than tactile sensation, such as visual effects, you will feel more secure. Therefore, in the present embodiment, although it is a simple rotation operation, fine adjustment and coarse adjustment can be analogly performed according to the operation situation, and between coarse adjustment and fine adjustment can be switched without a sense of incongruity, and digital adjustment can be performed. It was also possible to send supplementary information according to that and give the user a sense of security and concentrate on the operation.

  The state determination unit 115 determines a state such as an analog use state or a digital use state according to the user's intention to use. For example, if the device 100 is a camera, it is determined as analog use when the subject is manually focused, and it is determined as digital use when exposure correction is performed. This determination may be made according to camera settings, but is not limited to this, and may be made automatically according to the shooting scene, for example. For example, at the start of the operation, the adjustment value (control amount) changes greatly with respect to the operation amount and moves roughly, but it is also possible to perform control such that the adjustment value gradually changes with respect to the operation amount. . That is, in the switching to a mode other than the fine adjustment mode including the fine adjustment mode in which the change in the operation result with respect to the rotation amount related to the rotation of the operation unit becomes fine and the change in the operation result with respect to the rotation amount related to the rotation of the operation unit does not become fine, A non-uniform mode in which the relationship between the adjustment amounts is non-uniform may be set. In this case, this can be achieved by the conversion unit changing the conversion rate for converting the operation amount and the control amount.

  The situation determination unit 115 functions as a setting unit for setting either analog adjustment or digital adjustment for the operation by the ring-shaped operation unit. In the case of an analog specification, when the distance of the subject changes frequently, the zoom operation may be selected on the assumption that the angle of view is not determined. Also, when the overall contrast is low, the user may assume that he / she wants to focus and switch to the focusing specification. In the digital switching mode, exposure compensation may be selected in a scene where there is a large difference in brightness or a scene where the exposure value is saturated even though there is a high saturation. If the distance distribution is large, the aperture control may be selected. At the time of automatic specification switching based on such scene determination, it is possible to eliminate misunderstandings by displaying the adjustment contents.

  The control unit 101 has a CPU (Central Processor Unit), and controls the device 100 according to a program stored in a storage unit (not shown). In addition, the control unit 101 includes an operation determination unit 103, a notification control unit 104, and a conversion unit 105. Each of these units may be configured in whole or in part by hardware, and the function may be executed by software.

  The operation determination unit 103 inputs an operation signal corresponding to the operation state from the operation unit 113 and determines the operation state. In the case of a ring-shaped operation unit, the amount of rotation is determined, but the rotation speed, the number of operations, repetition of operations, and the like may be determined. In other words, when the same operation is performed many times, for example, when the image of the adjustment result is not visible change, the camera judges and switches to coarse tone, or the image is changing rapidly If the user is confused, it may be determined by image change and switched to fine adjustment. It is also possible to make a rough adjustment at the beginning of the operation and fine adjustment after the specific amount is adjusted. It is possible to devise switching to a progressive mode, which will be described later, depending on the rotation width and speed. If the rotation speed is fast, coarse adjustment (the coefficient when converting the operation amount and adjustment amount is large), and if it is slow, it is fine adjustment (the coefficient when converting the operation amount and adjustment amount is small). Although it is good, the user is confused when the rough and fine adjustments suddenly change, so when changing from the coarse adjustment to the fine adjustment, gradually change the coefficient when converting the manipulated variable and adjustment amount to give a continuity. This is desirable from the user's perspective.

  The conversion unit 105 inputs the determination in the operation determination unit 103 and the situation determination in the situation determination unit 115, and converts the operation amount of the operation unit 113 into an operation amount according to the use situation. For example, when a digital operation is performed, output is performed every time a predetermined threshold value is exceeded so that a discrete value is obtained. On the other hand, when an analog operation is performed, according to an input value. The value is converted so as to obtain the value, and output to the notification control unit 104. The conversion unit 105 is non-uniform with respect to the change in the operation result with respect to the rotation amount at the first operation position related to the rotation of the ring-shaped operation unit and the second operation position related to the rotation of the operation unit. It functions as a conversion unit that converts to. When the analog adjustment is set by the setting unit, the rotation angle of the ring-shaped operation unit is uniformly converted. On the other hand, when the digital adjustment is set, the rotation angle of the ring-shaped operation unit is changed. It also functions as a conversion unit that performs conversion so as to perform nonuniform conversion.

  The notification control unit 104 inputs a conversion result from the conversion unit 105 and performs drive control for causing the notification unit 114 to make a notification appealing to the user's five senses. The notification unit 114 may use a visually appealing display panel, an LED capable of switching light emission, may use an auditory appealing speaker that emits a specific sound, and may be tactilely appealing vibration. A piezoelectric element or the like that generates the above may be used. The notification unit 114 functions as a notification unit that makes a notification based on the conversion result by the conversion unit. That is, since the amount of variation (operation amount) of the operation unit is changed to the adjustment amount by a specific conversion process, the user feels uncomfortable without the notification unit, but in the present embodiment it is notified and reduced. In addition, more user-friendly adjustment is possible in consideration of the user's will.

  Next, the control operation in the present embodiment will be described using the flowchart shown in FIG. This flow is executed by the CPU controlling each unit in accordance with a program stored in the storage unit in the control unit 101. Here, it is preferable that the setting unit for setting one of the modes does not intervene with other switch operations, and can be concentrated on the operation if switched by the operation of the ring-shaped operation unit. For example, it is assumed that the operation speed, operation amount, operation method, operation time, operation timing, and the like are switched.

  When the flow shown in FIG. 2 is entered, it is first determined whether or not the mode is the analog mode (S1). Here, according to the determination result from the situation determination unit 115, it is determined whether or not the operation intended by the user is analog.

  If the result of determination in step S1 is analog mode, then operation determination is performed (S3). Here, the operation determination unit 103 determines whether or not the operation signal from the operation unit 113 has an operation amount. That is, it is determined whether or not the operation unit 113 has been operated. If the result of this determination is that there is no operation, there is no need to make adjustments or settings according to the operation amount, and there is no need to notify, so nothing is done and the process returns to step S1.

  On the other hand, if the result of determination in step S3 is that there is an operation, the variable is switched to analog (continuous) according to the operation amount (S5). Here, the conversion unit 105 takes the adjustment value and the set value variable as analog values that correspond linearly in accordance with the operation signal from the operation unit 113.

  Subsequently, the variable is notified in analog according to the operation amount (S7). Here, the notification control unit 104 notifies from the notification unit 114 according to the operation amount (operation signal). The notification unit 114 notifies the operation amount in a 1: 1 correspondence. For example, it is linear with respect to the operation signal and is visually displayed on the display unit in accordance with the operation signal. When the notification is made, the process returns to step S1.

  In addition, in order to express the feature of analog operation (the control amount changes continuously according to the operation amount), the expression of 1: 1 was taken, but this represents a numerical value for the amount of rotation of the ring-shaped operation unit. This means that control is performed with a control amount in which a specific coefficient is applied to the change. Of course, this coefficient may change depending on the situation, and the operation result with respect to the rotation amount at the first operation position related to the rotation of the ring-shaped operation unit and the second operation position related to the rotation of the operation unit. The change (the above coefficient) may be different. Such switching of the coefficients is expressed as “uneven”. However, in this case of non-uniform conversion (conversion), the user may be confused because operations and adjustments suddenly change. In order to make this change easy to understand for the user, it is desirable to have a notification section that converts and notifies information so as to notify it. With the recent evolution of display technology, display control that compensates for such a feeling of operation has become possible. However, the notification method is not limited to visually appealing display, and may be sound or vibration that conveys information about the conversion. In other words, when it changes finely, it makes a fine “Karikari” or “jijiji” voice or vibration along the time axis at the time of operation. You may make it produce rough voices and vibrations, such as “Ticky”.

  If the result of determination in step S1 is not analog mode, operation determination is next carried out (S11). Here, as in step S3, the operation determination unit 103 determines whether or not the operation signal from the operation unit 113 has an operation amount. If the result of this determination is that there is no manipulated variable, nothing is done and processing returns to step S1.

  If the result of determination in step S11 is that there is an operation amount, then the variable is switched to digital according to the operation amount tail (S13). The conversion unit 105 sets the variable of the adjustment value or the set value as a digital value corresponding to the operation signal from the operation unit 113.

  Subsequently, the variable is digitally notified according to the operation amount (S15). Here, the notification control unit 104 notifies from the notification unit 114 according to the operation amount (operation signal). Announcement is made from the notice unit 114 with respect to the operation amount corresponding to n: 1 with hysteresis. For example, the numerical value is discretely changed so that the specific number is 1 when the operation signal exceeds the predetermined value 1, and the specific number is 2 when the operation signal exceeds the predetermined value 2, and this conversion has hysteresis. May be. When this conversion is performed, the notification unit 114 performs notification based on the conversion result. When the notification is made, the process returns to step S1.

  In step S15, it was described that hysteresis may be provided in the conversion. This is because when the ring-shaped operation member moves lightly, the user's stress increases when the adjusted value changes with a slight touch. Therefore, it is effective to provide a dead band until the next value is set during rotation, and to increase the dead band after it is set once. It is also an advantageous effect in the present embodiment that the rotation position (operation amount) and the adjustment value can be freely changed, and the conversion unit changes this association according to the situation. Such an association change may also give a sense of discontinuity. As described in the case of analog, such an operation amount may be uncomfortable when the user strictly remembers the previous operation, and is preferably displayed on the notification unit. When the operation amount of the operation feeling and the numerical value to be adjusted are changed by specific conversion in this way, the notification unit has an effect of eliminating the uncomfortable feeling. This may be visual or appeal to hearing or touch.

  In the control flow according to the present embodiment, in steps S5 and S7, continuous control and display are performed in accordance with the operation amount, while in steps S13 and S15, one step and one step are performed with a specific amount of displacement. Control and display that change discontinuously. In other words, S5 and S7 correspond to 1: 1, and S13 and S15 correspond to multiple: 1.

  As described above, in this embodiment, by switching between analog control and digital control, the same operation member can be changed flexibly and flexibly according to the situation (method for controlling a device even in the same operation). Different controls). For this reason, it is possible to provide versatility to the operation member while miniaturizing and simplifying the operation member, and it is possible to reduce the size of the apparatus by simplifying the configuration. The user can confirm the notification result, determine whether the operation is correctly reflected in the device, and can operate with peace of mind. Further, since switching is not performed depending on the structure of the operation unit, customization can be easily performed regardless of design restrictions such as the size and displacement of the operation unit.

  Next, an example applied to a digital camera as a second embodiment of the present invention will be described. This digital camera has an imaging unit, and the imaging unit converts the subject image into image data, and based on the converted image data, the subject image is displayed in live view on a display unit disposed on the back of the main body. . The photographer determines the composition and the photo opportunity by observing the live view display. During the release operation, image data is recorded on the recording medium. The image data recorded on the recording medium can be reproduced and displayed on the display unit when the reproduction mode is selected.

The user setting unit 4b records the result of setting the analog adjustment and digital adjustment relationships of the operation unit 23 and the rotation operation units 5a and 5b according to the user's preference. can do.

  The signal processing and control unit 1 includes a subject determination unit 1h, a display control unit 1i, a special effect processing unit 1f, a color correction unit 1g, a parameter change unit 11, a focus control unit 1t, an exposure control unit 1c, an aperture control unit 1d, an image It has a corner 1e. The signal processing and control unit 1 controls the operation of the entire camera in accordance with a program stored in the nonvolatile memory. The signal processing and control unit 1 functions as a setting unit for setting either analog adjustment or digital adjustment for the operation by the ring-shaped operation unit (for details, refer to S27 in FIGS. 9 and 10A, S29 etc.). Further, when the analog adjustment is set by the setting unit, the signal processing and control unit 1 uniformly converts the rotation angle of the ring-shaped operation unit, while when the digital adjustment is set, It also functions as a conversion unit that converts the rotation angle of the ring-shaped operation unit so as to be converted unevenly (for details, see S109 in FIG. 11A, S131 in FIG. 11B, S157 in FIG. 12A, 179 in FIG. 12B, etc.).

  The subject determination unit 1h detects the position and size of the subject's face based on the image data from the imaging unit 2, etc., and also determines the shooting scene etc. from the color and brightness distribution and distance information as necessary. Judgment is also made. The display control unit 1 i controls display on the EVF 8 a and the rear display unit 8. In the present embodiment, when the user is looking into the EVF 8a based on the detection signal of the eye sensor 12, the display is performed on the EVF 8a. On the other hand, when the user is not looking into the EVF 8a, the display is displayed on the rear display unit 8. Do.

  The special effect process 1f performs image processing according to the set special effect on the image data from the imaging unit 2 when the special effect process (also referred to as art filter) is set as the shooting mode. .

  The color correction unit 1g performs color correction on the image data from the imaging unit 2 by the user operating the rotation operation units 5a, 5b, etc., for example, changing the saturation or changing the hue. By changing the saturation, the white to gray to black adjustment can be changed, and by changing the hue, the image can be tinted, bluish or reddish. Can be changed.

  The focus control unit 1t performs automatic focus adjustment based on the image data from the imaging unit 2, and performs manual automatic focus adjustment of the user in the operation units such as the rotation operation units 5a and 5b and the operation unit 23. The angle-of-view unit 1e performs zooming of the optical system 21 according to the rotation direction and the rotation operation amount when the rotation operation units 5a and 5b function as zooming operation members.

  The exposure control unit 1c controls the shutter based on the subject luminance based on the image data from the imaging unit 2 and the set value such as the shutter speed set by the user in the operation determination unit 5. The aperture control unit 1d controls the aperture based on the subject brightness based on the image data from the imaging unit 2 and the set value such as the aperture value set by the user in the operation determination unit 5. The parameter changing unit 11 outputs appropriate parameters to the focus control unit 1t, the exposure control unit 1c, the aperture control unit 1d, the angle of view unit 1e, the special effect processing unit 1f, and the color correction unit 1g. Make a change.

  As the switching control of the camera body 10 shown in FIG. 3, analog control is preferable when it is desired to finely adjust the focus of the subject image, zooming for adjusting the subject composition, or the like. On the other hand, digital change is preferable for the mode switching such as the shooting mode and special effect processing. In addition, aperture, shutter speed, exposure correction, and the like are digitally changed numerically when the image is displayed with an effect, and digital switching is more frequent than before. It is better to respect the long-time operation of the product.

  Switching control of the camera body 10 will be described with reference to FIG. 4A and 4B show a state where the user holds the camera body 10 and operates the operation unit. In FIG. 4A, while the user's left hand 20L rotates the operation unit 23 provided on the interchangeable lens 20, the right hand puts a finger on the release button 6 and waits for the shutter timing. FIG. 4B shows a state in which the rotation operation units 5 a and 5 b are respectively rotated and adjusted while viewing the display on the rear display unit 8. For example, the rotation operation unit 5a is operated with the thumb of the right hand 20R, the rotation operation unit 5b is operated with the index finger, and operations such as adjusting saturation and hue are performed.

  FIG. 4C shows a display example on the rear display unit 8. Since the user takes a picture while viewing the live view image displayed on the EVF 8a or the rear display unit 8, it is desirable that an image close to the finished image is displayed for focusing, exposure correction, and the like. For this reason, it is helpful to perform the auxiliary display 8d when displaying an image in conjunction with the operation of the operation unit. In the auxiliary display 8d, a segment (a blackened portion in 8d) moves in accordance with the operation of the operation unit.

  Next, the case where the exposure correction value is switched by the operation member will be described with reference to FIGS. 5 and 6. When exposure is determined as a whole including the background and the person, as shown in FIG. 5A, the background is bright, while the person is dark, and halfway expression may occur. In this case, by exposure correction, it is possible to set the exposure of the subject mainly as shown in FIG. 5B, and the exposure of the background subject as shown in FIG. 5C. When the user is observing the EVF 8a, as shown in FIG. 5 (d), the auxiliary display 8d is devoted to photographing, so the fineness of digital switching can be made finer. Also good.

  FIG. 6 is a graph showing the size of image data along the line L1 in the image of FIG. In a scene as shown in FIG. 5 (a), as shown in FIG. 6 (a), exposure control is performed so that the average image signal falls within the dynamic range D of the electronic circuit for photographing display. When the exposure level is increased, as shown in FIG. 6B, the exposure of the face portion can be made appropriate (corresponding to the image of FIG. 5B). Further, when the exposure level is lowered, as shown in FIG. 6C, the background exposure level is optimized so that the background color can be seen well (corresponding to the image of FIG. 5C). Thus, the exposure level adjustment operation may be changed digitally.

  As described above, since the exposure adjustment operation is performed digitally as a long-standing practice, an auxiliary display 8d simulating an operation ring that is digitally switched is displayed in FIG. A click sound may be generated at the time of this digital switching. The reason why the digital operation is good is that the brightness distribution is discrete.

  A case where focus switching (focus adjustment) is performed using an operation member will be described with reference to FIGS. 7 and 8. In a shooting scene as shown in the rear display unit 8 in FIG. 7, in the normal focusing (automatic focus adjustment), as shown in FIG. It is difficult to focus on the subject in front as shown in FIG. 7B or focus on the subject in the back as shown in FIG.

  FIG. 8 shows the distance distribution of the subject along the line L2 in the scene shown in the rear display unit 8 of FIG. When the focusable range is limited, as shown in FIG. 7, only a subject at a specific distance can be focused (see FIGS. 8B and 8C). Therefore, the user wants to adjust the focus range RI. However, the distance distribution is often continuous rather than discrete, and even an amateur knows subjects that are not in focus and subjects that are not in focus. Adjust and analog operation is convenient. Therefore, an analog display is suitable for such adjustment.

  As described above, in the present embodiment, the auxiliary display 8d is used both as a digital display (for example, exposure correction shown in FIG. 5) and an analog display (for example, focusing shown in FIG. 7). Therefore, the switching between the two displays may be performed at predetermined time intervals (for example, 1 second), for example.

  In the example shown in FIG. 9, the auxiliary display 8d is displayed on the upper right side of the rear display unit 8. However, the auxiliary display 8d ′ for analog adjustment as shown in FIG. 9A and the auxiliary display 8d ′ shown in FIG. The auxiliary display 8 ″ for digital adjustment as shown in b) is alternately displayed. Now, assuming that the user is focusing the subject, the auxiliary display 8d ′ for analog adjustment is displayed. During this period, the operation of the operation unit 23, etc. may be performed, whereby the analog display mode is set, and this mode is maintained for the second predetermined time after the operation is completed.

  Next, the focus adjustment operation in this embodiment will be described with reference to the flowcharts shown in FIGS. 10A to 10C. This flow is executed by the CPU in the signal processing and control unit 1 controlling each unit in accordance with the stored program in cooperation with the CPU in the control unit 27.

  When the focus adjustment flow shown in FIG. 10A is entered, it is first determined whether or not the camera is in shooting mode (S21). Here, the camera body 10 determines which mode, such as a shooting mode or a playback mode, is set. In the present embodiment, the shooting mode is set as the default mode.

  If the result of determination in step S21 is shooting mode, it is next determined whether or not a user has detected by the eye sensor (S23). As described above, when the user approaches the eyepiece to look into the EVF 8a, the eye sensor 12 outputs a detection signal.

  If the result of determination in step S23 is that the user has been detected by the eye sensor, rear live view display is performed (S25). Here, based on the image data from the imaging unit 2, the subject image is displayed on the rear display unit 8 in live view. Further, when live view is displayed for the first time, AE (automatic exposure) and AF (automatic focus adjustment) are performed. Thereafter, the image data is read at predetermined time intervals, and the live view display is updated.

  Once the live view display is performed, it is next determined whether or not a predetermined time has elapsed before or after the ring operation (S27). Here, as described with reference to FIG. 9, in this embodiment, the auxiliary display 8d ′ for analog adjustment and the auxiliary display 8d ″ for digital adjustment are switched at predetermined time intervals. When there is an operation, this switching is stopped for a predetermined time, and in this step, it is determined whether or not it is in this switching stop period.

  If the result of determination in step S27 is that there is no switching stop period, ring alternate display is carried out (S29). Here, one of the auxiliary display 8 'for analog adjustment and the auxiliary display 8d "for digital adjustment is displayed at predetermined time intervals.

  If the ring alternate display is performed in step S29, or if the result of determination in step S27 is in the switching stop period, it is determined whether or not there has been a ring operation (S31). Here, it is determined whether or not the operation unit 23 has been rotated.

  If the result of determination in step S31 is not ring operation, it is determined whether or not there is another dial operation (S33). It is determined whether or not the operation unit 23 or the dial operation unit of the rotation operation units 5a and 5b.

  If the result of determination in step S33 is that other dials have been operated, the ring display is turned off (S35) and various settings are switched. Here, the auxiliary display 8d displayed in the rear display unit 8 is turned off, and the setting display corresponding to other dials is switched. In the present embodiment, when the operation unit 23 is rotated, the segment portion in the auxiliary display 8 is rotated and displayed according to the rotation. When the other dial is operated, it is misunderstood that the segment portion of the auxiliary display 8d does not rotate. Therefore, the auxiliary display 8d is deleted. If there is no risk of misunderstanding, it may not be erased. If the user is afraid that the setting result will change, the setting result may be kept displayed, or may be selected by the user.

  If various settings are switched in step S37 or if the result of determination in step S31 is a ring operation, it is next determined whether or not to perform exposure correction (S39). As described above, since the auxiliary display 8d ′ for analog adjustment and the auxiliary display 8 ″ for digital adjustment are alternately displayed on the auxiliary display 8d, in this step, the operation unit 23 or the rotation operation unit is displayed. The determination is made based on the timing at which 5a and 5b are operated.

  If the result of determination in step S39 is exposure correction, exposure correction is performed (S41). Here, the exposure control unit 1c changes the exposure correction value according to the ring operation. That is, as described with reference to FIG. 5, when the user performs a ring operation, the exposure control unit 1 c performs exposure correction according to the ring operation, and a live view image according to the exposure correction is displayed on the rear display unit 8. Is done. At this time, since the auxiliary display 8d is displayed on the rear display unit 8, the user can make an adjustment while viewing the auxiliary display 8d (in this case, an auxiliary display for digital adjustment). Detailed operation of this exposure correction will be described later with reference to FIGS. 11A to 11C. When the ring operation is stopped and the exposure correction operation is completed, the process returns to step S21.

  If the result of determination in step S39 is not exposure correction, focus adjustment is performed (S43). In the present embodiment, since the operation by the operation unit 23 or the like is assigned to exposure correction and focus adjustment, focus adjustment is performed when exposure correction is not performed. Here, the focus control unit 1b performs focus adjustment according to the ring operation. That is, as described with reference to FIG. 7, when the user performs a ring operation, the focus control unit 1 b performs focus adjustment according to the ring operation, and a live view image corresponding to the focus is displayed on the rear display unit 8. Is done. Adjustment can be performed while looking at (in this case, auxiliary display for analog adjustment). Detailed operation of this focus adjustment will be described later with reference to FIGS. 12A to 12C. When the ring operation is stopped, the focus adjustment operation ends.

  If the focus adjustment in step S43 is performed or if the result of determination in step S33 is that there is no other dial operation, it is next determined whether or not it is a shooting operation (S45). Here, it is determined whether or not the release button is fully pressed based on a signal from the release SW 6. If the result of this determination is that there is no shooting operation, processing returns to step S21.

  On the other hand, if the result of determination in step S45 is a shooting operation, shooting recording is performed (S47). Here, during the exposure time determined by the shutter speed, the imaging device exposes the subject image, and after the exposure time has elapsed, the image data from the imaging unit 2 is read, and the read image data is read by the signal processing and control unit 1. Image processing for image recording is performed, and image data is recorded in the recording unit 4. When the photographing recording is completed, the process returns to step S21.

  If the result of determination in step 23 is that a user is detected by the eye sensor, EVF live view display is performed (S26). Here, since the user is looking into the EVF 8a, the subject image is displayed on the EVF 8a without performing live view display on the rear display unit 8. Further, when live view is displayed for the first time, AE (automatic exposure) and AF (automatic focus adjustment) are performed. Thereafter, the image data is read at predetermined time intervals, and the live view display is updated.

  When live view display is performed, the subsequent processing is the same as step S27 and subsequent steps shown in FIG. 10A except that display is performed on the EVF 8a instead of the rear display unit 8. The same step number is assigned and detailed description is omitted. However, in the exposure correction in step S41 of FIG. 10A and the focus adjustment in step S43, the auxiliary display 8d is a fine display for EVF as shown in FIG. In other words, even the auxiliary display for digital adjustment and analog adjustment are made into smaller segments than those displayed on the rear display unit 8 respectively.

  If the result of determination in step S21 (FIG. 10A) is not shooting mode, it is determined whether or not playback mode is set (S51). When the user sets the playback mode, the playback button in the operation determination unit 5 is operated, and in this step, the determination is made based on the operation state of the playback button.

  If the result of determination in step S51 is that playback mode has been set, image playback is performed (S53). Here, the image data recorded in the recording unit 4 is read and displayed on the rear display unit 8 or the EVF 8a.

  Once image reproduction has been carried out, it is next determined whether or not there is a change (S55). There are cases where an operation member in the operation determination unit 5 is operated during image reproduction, and an image forwarding operation, an image returning operation, an image enlargement operation, a thumbnail display operation, and the like are performed. Here, it determines based on the detection result in the operation determination part 5. FIG.

  If the result of determination in step S55 is that a change operation has been made, image change is performed (S57). Here, the image is changed in accordance with the operation content determined by the operation determination unit 5.

  If the result of determination in step S51 is not playback mode, image file acquisition is performed (S59). Here, an image file is acquired from the outside of the camera body 10 by wire or wireless via the communication unit 14.

  If an image file is acquired in step S59, or if an image is changed in step S57, or if the result of determination in step S55 is that there is no change operation, processing returns to step S21.

  Next, focus adjustment in step S43 (S43a) will be described with reference to FIGS. 11A to 11C. The focus adjustment is an analog adjustment as described above, and the focus lens continuously changes according to the rotation amount of the ring-shaped operation member, and the auxiliary display 8d also changes the segment continuously according to this. .

  When the focus adjustment flow shown in FIG. 11A is entered, it is first determined whether or not the fine adjustment mode is set (S101). When performing the rotation operation of the ring-shaped operation member, the user may repeatedly move around the same angle in order to find the in-focus point when performing fine adjustment. When such movement is detected, the fine adjustment mode is set in step S113 described later. In step S101, it is determined whether or not the fine adjustment mode is set.

  As a result of the determination in step S101, if the fine adjustment mode is not set, that is, if it is displayed on the rear display unit 8, then an operation determination is performed (S103). Here, it is determined whether or not the operation unit 23 and the rotation operation units 5a and 5b of the ring-shaped operation member have been operated.

  If the result of determination in step S103 is that a ring-shaped operating member has been operated, next, the rotation angle θ is determined with the time of operation as the initial position (S105). Here, the rotation angle θ from the initial position is detected with the ring-shaped operation member as the initial position.

  Once the angle θ is determined, it is next determined whether or not the angle θ is greater than or equal to the limiter (S107). The focus lens can be driven from the closest end to the infinity end. In this step, based on the rotation angle θ detected in step S105, it is determined whether it is outside the closest end or the infinity end (that is, whether it is greater than the limiter).

  If the result of determination in step S107 is not greater than the limiter, lens driving is performed according to the rotation angle θ (S109). Here, the drive unit 24 drives the focus lens of the optical system 21 according to the rotation angle detected in step S105. For example, the lens is driven by 500 μm at a rotation angle θ of 10 degrees. This driving amount is an example, and may be changed as appropriate according to the characteristics of the lens.

  Further, the driving state is displayed on the auxiliary display portion 8d for lens driving. The segment display arranged in a circle (annular display) in the auxiliary display portion 8d is changed according to the total drive amount and the current drive amount. That is, as shown in FIG. 11C (a), in the auxiliary display 3d displayed in an annular shape, the total drive amount 300 is shown on the lower side and the current drive amount 310 is shown on the upper side. Thereby, since the drive amount of this operation is compared with the drive amount from the initial position, the adjustment is easy.

  Once the lens is driven according to the rotation angle θ, it is next determined whether or not the same range is repeatedly moved (S111). Here, as described above, it is determined whether or not the user is performing fine adjustment driving. For example, the determination is made based on whether the driving direction is changed alternately between the clockwise direction and the counterclockwise direction within a predetermined time.

  If the same range is repeatedly moved as a result of the determination in step S111, the fine adjustment mode is set (S113).

  When the fine adjustment mode is set in step S113, or when the same range is not repeatedly moved as a result of the determination in step S111, or when the determination result in step S107 is greater than the limiter, or the determination result in step S103. When the ring-shaped operation member is not operated, the focus adjustment flow is terminated and the original flow is restored.

  If the result of determination in step S101 is that the fine adjustment mode has been set, it is determined whether or not a predetermined time has elapsed since setting (S121). Here, it is determined whether or not a predetermined time or more has elapsed since the fine adjustment mode was set in step S113. The predetermined time is reset when there is no specific time operation such as an adjustment operation after the user sets the fine adjustment mode. Usually, the time required to start focusing by performing other operations or the like, that is, about several tens of seconds is sufficient.

  If the result of determination in step S121 is that the predetermined time has not elapsed, operation determination is performed as in step S103 (S123). Here, it is determined whether or not the operation unit 23 and the rotation operation units 5a and 5b of the ring-shaped operation member have been operated.

  If the operation is performed as a result of the determination in step S123, the rotation angle θ is determined with the operation time as the initial position, similarly to step S105 (S125). Here, the rotation angle θ from the initial position is detected with the ring-shaped operation member as the initial position.

  Subsequently, it is determined whether or not the movement is intense (S127). Here, it is determined whether or not the rotation angle θ detected in step S125 is large per unit time. In step S121 and subsequent steps, the fine adjustment mode is entered, but the user may move the operation member of the ring-shaped operation greatly for the sparse adjustment instead of the fine adjustment. In this step, it is determined whether or not the movement is such that it can be said that sparse adjustment has been made.

  If the result of determination in step 127 is not intense movement, it is next determined whether or not it is greater than or equal to the limiter, as in step S107 (S129). Here, based on the rotation angle θ detected in step S125, it is determined whether it is outside the closest end or the infinity end (that is, whether it is greater than or equal to the limiter).

  If the result of determination in step S129 is not greater than the limiter, lens driving is performed according to the rotation angle θ (S131). Here, the drive unit 24 drives the focus lens of the optical system 21 according to the rotation angle detected in step S125. For example, when the rotation angle θ is 10 degrees, the lens is driven by 50 μm. Compared with the case of the sparse adjustment in step 109, the driving amount of the focus lens is set to 1/10. This driving amount is an example, and may be changed as appropriate according to the characteristics of the lens.

  Further, the driving state is displayed on the auxiliary display portion 8d for lens driving. The segment display arranged in a circle (annular display) in the auxiliary display portion 8d is changed according to the total drive amount and the current drive amount. That is, as shown in FIG. 11C (b), in the auxiliary display 3d displayed in an annular shape, the entire drive amount 310 is shown on the lower side and the current drive amount 330 is shown on the upper side. It can be seen that the drive amount is smaller than in the case of the sparse adjustment. As a result, the drive amount and the operation range of the current operation are compared with the drive amount and the operation region from the initial position, so that the user can easily make an intuitive determination and adjustment.

  As a result of the determination in step S121, if the predetermined time has elapsed, or if the result of determination in step S127 is that there is intense movement, the fine adjustment mode is reset (S133). Since the predetermined time has elapsed or the user's adjustment operation has changed to sparse adjustment, the fine adjustment mode is reset and the normal mode is restored.

  If the fine adjustment mode is reset in step S133, or if the result of determination in step S129 is greater than or equal to the limiter, or if lens driving is performed according to the rotation angle θ in step S131, or the result of determination in step S123 is If is not done, the focus adjustment flow ends and the flow returns to the original flow.

  Thus, in the focus adjustment flow, when a ring-shaped operation member (such as the operation unit 23) is operated, analog adjustment is performed according to the amount of rotation operation. That is, the focus lens is driven according to the rotation angle θ (S109, S131). In addition, during the focus adjustment, analog display is performed on the auxiliary display unit 8d (see FIG. 11C). For this reason, when the user rotates the ring-shaped operation unit, the focus lens is driven according to the rotation angle, and the driving amount at that time is displayed on the auxiliary display unit 8d, so that it is easy to adjust the focus.

  In the focus adjustment flow, the fine adjustment mode is entered when the ring-shaped operation member (such as the operation unit 23) is repeatedly moved within the same range (S113). In the fine adjustment mode, the drive amount of the focus lens is reduced with respect to the rotation angle of the ring-shaped operation member. For this reason, the user can easily perform fine adjustment. Further, the display of the auxiliary display unit 8d at this time also narrows the range of the current driving amount 330, and the user can easily understand how much the actual driving is performed.

  Next, exposure correction in step S41 (S41a) will be described with reference to FIGS. 12A to 12C. The exposure correction is a digital adjustment as described above, and the correction value changes discretely according to the rotation amount of the ring-shaped operation member, and the auxiliary display 8d also changes the segment discretely accordingly. .

  When the exposure correction flow shown in FIG. 12A is entered, it is first determined whether or not the progressive mode is set (S151). The user may desire a total movement of these movements while moving little by little. This operation method is referred to as a progressive mode, and it is determined whether or not the progressive mode is operated in step S159 described later. If the operation has been performed, the progressive mode is set in step S161. In step S151, it is determined whether the progressive mode has been set.

  If the result of determination in step S151 is that there is no progressive mode, then operation determination is performed as in step S31 (S153). Here, it is determined whether or not the ring-shaped operation member (operation unit 23, rotation operation units 5a and 5b) has been rotated.

  If the result of determination in step S153 is that rotation has been performed, the rotation angle θ is determined with the time of operation as the initial position (S155). Here, the rotation angle θ from the initial position is detected with the ring-shaped operation member as the initial position.

  Next, when it enters the specific range, the display advances one block and the corresponding control is performed (S157). The exposure correction is a digital adjustment, and does not change the exposure correction value in a one-to-one correspondence with the rotation angle of the operation member, and is the same correction value within a specific range. That is, a correction value is determined for each range, and the correction value changes discretely. In this step, the exposure correction value is determined by determining in which range the rotation angle θ detected in step S155 falls. When the exposure correction value is determined, the exposure correction value is displayed on the auxiliary display unit 8d, and the live view image is displayed with the correction effect.

  Next, it is determined whether or not the same range is repeated (S159). As described above, it is determined based on the rotation angle θ detected in step S155 whether the user is repeatedly moving in the same range, that is, whether the user is moving the clockwise direction and the counterclockwise direction alternately at the same angle. To do.

  If the result of determination in step S159 is that the same range has been repeatedly moved, the progressive mode is set (S161). In the present embodiment, when not in the progressive mode, the normal mode is set (the normal mode is the default mode). The normal mode means that the user performs a rotation operation by a series of operations while holding the operation member. The progressive mode is different in that the rotation angle is observed by accumulating small operations while the rotation angle is viewed from the start point to the end point of the rotation operation without performing such accumulation in the normal mode.

  If the progressive mode is set in step S161, or if the result of determination in step S153 is that there is no operation, or if the result of determination in step S159 is that the same range has not been repeatedly moved, the flow of exposure correction ends. And return to the original flow.

  If the result of determination in step S151 is that the progressive mode has been set, it is determined whether or not a predetermined time has elapsed since it was set (S171). Here, it is determined whether or not the time from when the progressive mode is set in step S161 has exceeded a predetermined time. Since the resetting is performed when there is no operation for a long time, another operation can be completed if the predetermined time is set to several tens of seconds after the user sets the progressive mode. Usually, the time required for focusing and zooming operations is sufficient.

  If the result of determination in step S171 is that a predetermined time has not elapsed since the setting, operation determination is performed as in step S155 (S173). Here, it is determined whether or not the operation unit 23 and the rotation operation units 5a and 5b of the ring-shaped operation member have been operated for exposure correction.

  If the operation is performed as a result of the determination in step S173, as in step S155, the rotation angle θ is determined with the operation time as the initial position (S175). Here, the rotation angle θ from the initial position is detected with the ring-shaped operation member as the initial position.

  Subsequently, it is determined whether or not the movement is intense (S177). Here, it is determined whether or not the rotation angle θ detected in step S175 is large per unit time. In step S171 and subsequent steps, the exposure correction progressive mode is entered. However, there is a case where the user does not have the progressive mode and the operation member for ring-shaped operation is moved greatly in the normal mode. In this step, it is determined whether or not the movement is such that the operation is performed in the progressive mode.

  If the result of determination in step S177 is that there is no intense movement, cumulative display and corresponding control are performed by repeating a specific ring operation (S179). Here, an auxiliary display unit 8d as shown in FIG. 12C is displayed on the rear display unit 8. In the auxiliary display portion 8d, an exposure correction value is displayed on a specific ring according to the progressive value by the repetitive operation. In FIG. 12C, the shaded portion indicates each exposure correction value, and the segment 340 indicates the position of the exposure correction value based on the progressive result.

  As a result of the determination in step S171, if the predetermined time has elapsed, or if the result of determination in step S177 is that there is a violent movement, the progressive mode is reset (S181). Since the predetermined time has elapsed or the user's adjustment operation has changed to the normal mode, the progressive mode is reset and the normal mode is restored.

  If the progressive mode is reset in step S181, or if the result of determination in step S129 is greater than the limiter, or if progressive display and corresponding control are performed in step S179, or the result of determination in step S173 is that no operation has been performed In this case, the exposure correction flow is terminated and the original flow is restored.

  Thus, in the exposure correction flow, when a ring-shaped operation member (such as the operation unit 23) is operated, digital adjustment is performed according to the amount of rotation operation. That is, the exposure correction value is changed every time the rotation angle θ exceeds the predetermined angle (S157, S179). In addition, during the exposure correction, digital display is performed on the auxiliary display portion 8d (see FIG. 12C). Therefore, when the user rotates the ring-shaped operation unit, the exposure correction value is changed every time the rotation angle exceeds a predetermined angle, and the exposure correction value at that time is displayed on the auxiliary display unit 8d. Easy to do.

  In the exposure correction flow, the progressive mode is entered when the ring-shaped operation member (operation unit 23, etc.) is repeatedly moved within the same range (S163). In the progressive mode, the exposure correction value is set by accumulating the rotation angle of the ring-shaped operation member. For this reason, when the user sets a large exposure correction value, the user need only repeat the rotation in small increments without performing a rotation operation at a large angle. Further, the display on the auxiliary display unit 8d at this time also displays the accumulated result, so that the user can easily understand how much the drive is actually performed. Analog adjustment (continuous adjustment) may be performed in such a manner that numerical values are determined by integrating the repeated operations. That is, the rotation amount accumulated by repetition may be obtained and the numerical value corresponding thereto may be adjusted. At this time, if the adjustment value change (converted) per accumulated rotation amount is increased, coarse adjustment is made, and if the change is reduced, fine adjustment is made. In this progressive method, adjustment is possible with a small movement, so it goes without saying that it is convenient in a situation where the adjustment result changes due to changes in distance, posture, camera shake, or the like.

  As described above, in each embodiment of the present invention, a ring-shaped operation unit (for example, the operation units 113 and 23, the rotation operation units 25a and 25b, etc.) capable of uniform operation with respect to the center of rotation, a ring A conversion unit (for example, conversion unit 105, S157 in FIG. 12A, S179 in FIG. 12B) that converts so as to notify the information to be converted unevenly with respect to the operation position of the shape operation unit, and a conversion result by the conversion unit It has a notification unit (for example, a notification unit 114, a back display unit 8, an EVF 8a, and a vibration unit 9) that performs a notification based on the notification unit. For this reason, it becomes possible to combine both the case where it is uniformly converted by the same ring-shaped operation member and the case where it is converted non-uniformly. Both continuous operation and discontinuous / discrete operation are possible, and the conversion method of the operation amount and the set value is switched depending on the situation and investigation, so fine adjustment, coarse adjustment, etc. by rotation or repeated operation are possible. You can choose freely and still do not confuse the user.

  In each embodiment of the present invention, a ring-shaped operation unit (for example, operation units 113 and 23, rotation operation units 25a and 25b) that can be rotated with respect to the rotation center, and an operation by the ring-shaped operation unit. A setting unit (for example, the situation determination unit 115, S27 and S29 in FIG. 10A, S29 and S29 in FIG. 10B) for setting either analog adjustment or digital adjustment, When the target adjustment is set, the rotation angle of the ring-shaped operation unit is uniformly converted (for example, the conversion unit 105, S109 in FIG. 11A, S131 in FIG. 11B, etc.), while the digital adjustment is set. In this case, a conversion unit that converts the rotation angle of the ring-shaped operation unit in a non-uniform manner (for example, conversion unit 105, S157 in FIG. 12A, S179 in FIG. 12B, etc.) and a conversion unit Notification unit that performs a notification on the basis of a result of conversion (e.g., notification unit 114, the rear display unit 8, EVF8a, vibration unit 9, etc.) has a, a. For this reason, analog operation and digital operation can be shared by the same ring-shaped operation member.

  In each embodiment of the present invention, the conversion unit can selectively execute non-uniform conversion and uniform conversion (for example, FIG. 9 and the like). It has a setting unit for setting one of them (for example, the situation determination unit 115, S27 and S29 in FIG. 10A, S29 and S29 in FIG. 10B). For this reason, non-uniform conversion and uniform conversion can be operated with the same ring-shaped operation unit.

  In each embodiment of the present invention, the setting unit alternately displays the non-uniform conversion display and the uniform conversion display on the notification unit (for example, S27 in FIGS. 9 and 10A). The conversion unit performs non-uniform or uniform conversion in accordance with the display of the notification unit when operated by the ring-shaped operation unit (for example, S31, S39, S41 in FIG. 10A). , S43 etc.). For this reason, the user can concentrate on the operation according to the situation without misunderstanding or confusion, enjoy the device operation, and without any special operation, either non-uniform conversion or uniform conversion at the timing The adjustment value can be set in the best way. As much as possible, it is possible to switch to various ring specifications in a form devoted to ring operation, without changing the way the device is held during ring operation.

  In each embodiment of the present invention, when the ring-shaped operation unit is repeatedly operated within a predetermined range, the fine adjustment mode is set (for example, S111 and S113 in FIG. 11A), and the conversion unit has the fine adjustment mode. When set, the conversion rate of conversion is changed (for example, S125 in FIG. 11B). For this reason, the user can automatically enter the fine adjustment mode by repeatedly operating the predetermined range, and does not need to perform a special operation (for example, operating a specific switch). Thus, it is preferable that the setting unit for setting various operation specifications does not intervene with other switch operations as described above. If the setting unit is switched by the operation of the ring-shaped operation unit, it is possible to concentrate on the operation. The speed may be switched according to the speed, amount of operation, operation method, operation time, operation timing, and the like. With this contrivance, the user can be immersed in the adjustment with the specifications switched to the optimum operation while confirming the output of the notification section. In addition, if an analog mode, a digital mode, or the like is set, parameters that are switched accordingly can be set according to the operation specifications.

  In each embodiment of the present invention, when the ring-shaped operation unit is repeatedly operated within a predetermined range, the progressive mode is set (see, for example, S159 and S161 in FIG. 12A), and the conversion unit performs the ring-shaped operation. Conversion is performed based on the cumulative operation amount of the unit (for example, S179 in FIG. 12B). For this reason, the user can automatically enter the progressive mode by repeatedly operating the predetermined range, and there is no need to perform a special operation (for example, operating a specific switch). The user can immerse himself in the adjustment with the specifications switched to the optimum operation while checking the output of the notification section.

  Further, in each embodiment of the present invention, the ring-shaped operation unit is provided with an operation range limiter (for example, S107 in FIG. 11A), and when the operation range limiter is exceeded, the ring-shaped operation unit is operated. The drive based on this is prohibited (for example, S107 Yes in FIG. 11A). For this reason, the adjustment beyond a predetermined range can be prohibited.

  Further, in each embodiment of the present invention, when the analog adjustment is set by the setting unit, the ring-shaped operation unit is provided with an operation range limiter (in the focus adjustment which is an analog adjustment, the limiter is detected. (S107 in FIG. 11A) On the other hand, when digital adjustment is set by the setting unit, the ring-shaped operation unit does not provide a limiter for the operation range (limiter detection is performed in exposure correction that is digital adjustment). For this reason, a limiter can be provided according to the nature of the adjustment.

  In each of the embodiments of the present invention, focus adjustment is performed as an analog adjustment value that is continuously changed one-to-one with respect to an input value, and discretely depending on whether or not the input value exceeds a threshold value. Although the exposure correction has been described as an example of the digital adjustment value to be changed, the present invention is not limited to this and can be applied to other adjustment values.

  In each embodiment of the present invention, the analog adjustment for uniformly converting the input value and the digital adjustment for converting the input value non-uniformly are alternately displayed as shown in FIG. This was done according to the input timing of the operation unit. However, the present invention is not limited to this. For example, it may be switched by another method such as setting one with an operation button.
