Yes.

JP 2012-237870 A

  In the drive control device of Patent Document 1, friction force is generated by a vibrator that is in contact with the operation ring. However, even by using the human vibration generated by the vibrator, the click feeling is changed by the strength of the human vibration. A pseudo-feel can be obtained. Various means have been devised as vibration generating means for generating vibrations, but the response time required for the amplitude of the vibration to reach a human-sensible amplitude varies from one unintelligible amplitude to another. When using the vibration generating means with a long response time in the drive control device of Patent Document 1, if the operation speed of the operation ring is fast, the vibration amplitude by the vibrator does not reach a human-visible amplitude, and the user uses the vibrator The frictional force and vibration on the operation ring cannot be felt. In addition, not only the amplitude but also the frequency is important in order to generate human-visible vibration. Even when the vibration frequency does not reach a human-visible frequency, the user may not feel the vibration even if the vibration is generated by the vibration generating means.

  An object of the present invention is to provide an electronic device capable of transmitting an appropriate vibration feel without depending on vibration generation means even when the operation speed of the operation unit is high.

  An electronic apparatus according to one aspect of the present invention uses an operation unit, a position detection unit that can detect an operation position of the operation unit, a vibration unit that generates vibration, and a detection signal output from the position detection unit. Control means for controlling the drive of the vibration means based on the information relating to the operation of the operation part measured in the above, wherein the control means has moved the operation part by a predetermined distance. When the operation time is smaller than the predetermined time, the vibration means is driven so as not to decrease the current vibration amplitude or frequency. When the operation time is larger than the predetermined time, the vibration means is Or it is made to drive so that a frequency may not be maintained.

  According to another aspect of the present invention, there is provided a method for controlling an electronic device, comprising: a position detection step for detecting an operation position of an operation unit; a vibration step for generating vibration; and a detection signal output in the position detection step. And a control step for controlling vibration in the vibration step based on the information relating to the operation of the operation portion, wherein the control portion moves the operation portion by a predetermined distance. If the operation time is smaller than the predetermined time, the vibration is controlled so that the current vibration amplitude or frequency does not decrease. If the operation time is larger than the predetermined time, the current vibration amplitude or frequency is not maintained. Thus, the vibration is controlled.

  According to the present invention, it is possible to provide an electronic device capable of transmitting an appropriate vibration feel without depending on vibration generation means even when the operation speed of the operation unit is high.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each figure, the same members are denoted by the same reference numerals, and redundant description is omitted.

  The main components of a digital camera 100 that is an example of an electronic apparatus according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is an external perspective view of the digital camera 100. FIG. 1A is a diagram of the digital camera 100 viewed from the front side (subject side). FIG. 1B is a diagram of the digital camera 100 as viewed from the back side (user side). In this embodiment, the direction in which a later-described photographic lens unit 105 provided in the digital camera 100 faces is the front side (subject side), and the reverse direction is the back side (user side). In the present embodiment, the digital camera 100 will be described as an example of the electronic device. However, the present invention is not limited to this, and can be applied to an electronic device having a function of transmitting a vibration feel to the user.

  The exterior of the digital camera 100 is formed by a front cover 101, a back cover 102, a top cover 103, and a bottom cover 104. A photographing lens unit 105 is provided on the front side of the digital camera 100 so as to protrude from the front cover 101 to the front side.

  The photographing lens unit 105 includes a photographing lens group including a plurality of lenses, a lens driving unit, a shutter driving unit, and an imaging unit. The lens driving means moves a part of the photographing lens group along the optical axis L of the photographing lens group to adjust the focal length, and moves a part of the photographing lens group along the optical axis L. Zooming drive means for performing shooting magnification change drive. The imaging means includes an optical sensor such as a CCD, and converts light that passes through the photographing lens group and is collected by the optical sensor into image information. The shutter driving unit is installed in a part of the optical path of the photographing lens group, and adjusts the light amount collected on the imaging unit to be appropriate by opening and closing the optical path with the shutter.

  The front side cover 101 serves as a component mounting base for the front side cover unit 120 that constitutes the front side of the digital camera 100. The front cover unit 120 includes an operation dial 110 that is an operation unit. The operation dial 110 is disposed around the photographing lens unit 105 and can be rotated around the optical axis L of the photographing lens unit 105. The user can change the setting value corresponding to the photographing function of the digital camera 100 set by the dial function setting means 109 by operating the operation dial 110 and changing the operation position. In the present embodiment, the operation dial 110 can be operated infinitely in both directions, but may be operated in a finite reciprocating manner. Further, instead of the operation dial 110, an operation unit capable of a reciprocating linear operation may be used as the operation unit.

  The upper surface side cover 103 is provided with a main power switch 106, a release switch 107, a zoom switch 108, and a dial function setting means 109. When the main power switch 106 is pressed, the digital camera 100 is turned on / off. When the release switch 107 is pressed, the optical information is converted into image information by the imaging means via the photographing lens unit 105, and the image information is recorded in a storage medium (not shown). The zoom switch 108 can be rotated within a predetermined angle around the release switch 107, and is urged so as to be held at the neutral position shown in FIG. The zoom switch 108 is rotated to the first rotation end side to move a part of the photographing lens group to the wide angle side, and is rotated to the second rotation end side to move a part of the photographing lens group to the telephoto side. The photographing function of the digital camera 100 is set according to the position of the dial function setting means 109 selected by the user. Functions that can be set include, for example, an “aperture mode” in which the user can select an aperture value, and a “focus mode” in which the user can select a focal length.

  The back cover 102 is provided with a display unit 111 made of, for example, a liquid crystal unit so as to face the user side. The display unit 111 displays image information acquired by the photographic lens unit 105, displays various settings of the digital camera 100, and image information recorded in a storage unit (not shown) that can be attached to and detached from the digital camera 100. Is read and displayed. The back grip 119 is fixed to the back side cover 102, and is a holding unit for placing the right thumb when the user holds the digital camera 100 with the right hand.

  The structure of the front side cover unit 120 is demonstrated using FIG. FIG. 2 is a diagram illustrating the configuration of the front cover unit 120. FIG. 2A is a perspective view of the front cover unit 120 as seen from the back side. FIG. 2B is an exploded perspective view of the front side cover unit 120.

  On the back side of the front cover 101, a frame 113 and a pulse ring 114 formed of resin are provided. The frame 113 is affixed to the front side cover 101 with a double-sided tape 112 in a state where the outer diameter portion of the cylindrical portion 113a protruding to the front side is fitted to the inner diameter portion of the opening 101a of the front side cover 101. . An inner diameter side of the cylindrical portion 113a is opened, and an operation dial 110 is inserted into the opening from the front side so as to be rotatable with respect to the frame 113. The frame 113 is arranged so as to be sandwiched between the operation dial 110 from the front side and the pulse ring 114 from the back side. The pulse ring 114 is provided with a plurality of locking holes 114a protruding to the front side. Further, the pulse ring 114 is provided with a gap 114b having the same shape at equal angular intervals. The operation dial 110 is provided with a locking portion 110a described later at a position corresponding to the plurality of locking holes 114a. When the locking portion 110a is locked in the locking hole 114a, the operation dial 110 and the pulse ring 114 are integrated, and when the operation dial 110 rotates, the pulse ring 114 also rotates with respect to the frame 113.

  The position detection means 116 detects the operation position of the operation dial 110. The position detection unit 116 includes a substrate unit 116a having two photo reflectors, and a flexible substrate unit 116b that transfers detection information acquired by the two photo reflectors to a control unit (not shown). The board portion 116 a is fixed to the frame 113 with screws 118 together with the holding member 115. In the present embodiment, the operation position of the operation dial 110 is detected by detecting the presence or absence of the gap 114b of the pulse ring 114 using the two photo reflectors of the substrate portion 116a. There are various other methods for detecting the operation position of the operation dial 110, such as using a photo interrupter, but any method can be used as long as the operation position of the operation dial 110 can be detected.

  The vibration unit 117 is in close contact with the frame 113 and is electrically connected to a control unit (not shown). The vibration unit 117 can generate vibration that can be felt by humans at least in part of the appearance of the digital camera 100. As the vibration means 117, for example, a piezoelectric actuator, a linear actuator, an ultrasonic motor, or an eccentric motor in which a weight is eccentrically attached from the rotation center is used.

  The vibration propagation path of the vibration means 117 will be described with reference to FIG. FIG. 3 is a diagram illustrating the configuration of the front cover unit 120. FIG. 3A is a rear view of the front cover unit 120. FIG.3 (b) is sectional drawing of the AA part of Fig.3 (a).

  In the pulse ring 114, a cylindrical portion 114c and a flange portion 114d are integrally formed. A plurality of locking holes 114a are provided at the end of the cylindrical portion 114c. The flange portion 114d is provided with a gap 114b having the same shape at equal angular intervals. The front and rear of the frame 113 are sandwiched between the operation dial 110 and the flange portion 114d, and the locking hole 114a and the locking portion 110a are locked, thereby restricting the movement of the integrated operation dial 110 and the pulse ring 114 in the front-rear direction. The The operation dial 110 includes a cylindrical portion 110b extending to the back side. By fitting the outer diameter portion of the cylindrical portion 110b to the inner diameter portion of the cylindrical portion 113a, radial movement with the rotation center of the operation dial 110 as the optical axis L is restricted.

  When the vibration means 117 vibrates, the vibration propagates directly to the frame 113. Since the cylindrical portion 113a and the cylindrical portion 110b are fitted, vibration is transmitted from the frame 113 to the operation dial 110. Further, since the frame 113 and the front side cover 101 are bonded with the double-sided tape 112, a part of vibration transmitted to the frame 113 is also transmitted to the front side cover 101. Therefore, the user can obtain a vibration feel not only in the operation dial 110 but also in other exterior parts holding the digital camera 100. The vibration means 117 may be provided not on the frame 113 but on the inner surface side of the digital camera 100 in contact with the rear grip 119. It is desirable that the vibration means 117 is disposed in a place where there is a high possibility that the user directly holds the digital camera 100 with fewer intervening parts so as not to attenuate the vibration.

  A method for detecting the operation position of the operation dial 110 by the position detection means 116 will be described with reference to FIG. FIG. 4 shows detection signals for the respective operation positions of the operation dials 110 of the two photo reflectors. In the following description, the two photo reflectors are referred to as PR1 and PR2. The air gap 114b is provided in the flange portion 114d for every rotation angle A degrees obtained by equally dividing 360 degrees around the optical axis L. The rotation angle A degree is one cycle. The flange portion 114d is provided with a gap 114b having an angle A / 2 degrees and a solid portion having an angle A / 2 degrees sandwiched between the gaps 114b. That is, the gaps 114b and the solid portions are alternately arranged every ½ cycle. PR1 and PR2 are arranged at an angle of 3A / 4 degrees (3/4 period) with respect to the optical axis L, which is the center of rotation, so that positions on the same rotation circumference can be detected. When detecting the gap 114b, PR1 and PR2 output a dark signal (LO) because the light passes through the gap 114b and the reflected light cannot be detected. Since PR1 and PR2 can detect reflected light when detecting the solid part, they output a bright signal (HI).

  In the present embodiment, it is assumed that the operation position detection of the operation dial 110 is started from the position where PR1 outputs HI and PR2 outputs LO in “initial stage”. In “1/8 period rotation”, the operation dial 110 is operated in the direction of the arrow for 1/8 period, and the pulse ring 114 also rotates together. PR1 outputs a detection signal indicating switching from HI to LO (H → L), and PR2 outputs LO. Hereinafter, in “2/8 cycle rotation” to “9/8 cycle rotation”, when the operation dial 110 is operated in the direction of the arrow every 1/8 cycle, the detection signals output by PR1 and PR2 are as shown in FIG. To change. The patterns of the detection signals of PR1 and PR2 are all different from “Initial” to “7/8 cycle rotation” immediately before one cycle rotation. Therefore, the rotation direction (operation direction) can be detected by comparing the current detection information by PR1 and PR2 with the next detection information output by operating the operation dial 110. If the boundary where PR1 or PR2 switches from HI to LO or LO to HI is difficult and it is difficult to determine whether the detection signal is HI or LO, it is determined that the determination is impossible, and rotation is performed by the detection signal from the next PR1 and PR2. The direction can be detected.

  In addition, the time at the time of switching from HI to LO, which is the end of the gap 114b detected by PR1 of “1/8 cycle rotation”, is determined as the measurement start time of the operation elapsed time T of the operation dial 110. In the present embodiment, the time interval (switching time interval) Ta from the measurement start time to the time of switching from HI to LO of PR1 that reappears with “9/8 cycle rotation” in the same direction rotation of the operation dial 110 is set. measure. The switching time interval Ta can be rephrased as an operation time when the operation dial 110 is moved by a predetermined distance. Since the switching from HI to LO is detected at every rotation angle A degrees, the rotational angular velocity (operation speed) of the operation dial 110 can be indirectly detected by measuring the switching time interval Ta. In this embodiment, PR1 is used to measure the switching time interval Ta, but PR2 may be used. Further, when measuring the switching time interval Ta, the switching from the HI to the LO during the rotation in the predetermined direction is used as a reference, but the switching from the LO to the HI may be used as a reference. In this embodiment, the method of detecting the operation direction and operation speed of the operation dial 110 using the pulse ring 114 and two photo reflectors has been described. However, the operation direction and operation of the operation dial 110 using other methods are described. The speed may be detected.

The electric circuit of the digital camera 100 will be described with reference to FIG. FIG. 5 is an electric circuit diagram of the digital camera 100. A power source 501 such as a battery is connected to the control means 509. The control means 509 has a built-in time measuring means for measuring time. The time measuring means is used when measuring the elapsed time of operation of the operation dial 110 and the operation time of the operation dial 110. The control unit 509 drives the photographing lens groups 502A and 502B via the magnification driving unit 503 when performing zooming driving, and only the photographing lens group 502B via the focus driving unit 505 when performing focal length adjustment driving. Drive. Further, the control unit 509 adjusts the amount of light exposed by the imaging unit 504 by driving the shutter 510a via the shutter driving unit 510 and controlling the aperture diameter and the aperture time. The imaging unit 504 is a sensor, and sends image information converted from optical information to the control unit 509. The control unit 509 controls the driving of the vibration unit 117 based on the detection information of the position detection unit 116 and the result of the timing unit built in the control unit 509. The storage unit 506 stores in advance position information of the operation dial 110 and information necessary for various shootings, and the control unit 509 reads out necessary information and stores necessary information. The storage unit 508 is a portable recording medium and is detachably connected to an I / O port 507 provided in advance in the digital camera 100. The control unit 509 records image information captured by the digital camera 100 in the storage unit 508, reads out the image information recorded in the storage unit 508, and displays the image information on the display unit 111. Dial function setting means 109 and position detection means 116 are connected to control means 509. When the detection signal received from the position detection unit 116 changes, the control unit 509 changes the setting value according to the shooting function selected by the dial function setting unit 109. The main power switch 106, the release switch 107, and the zoom switch 108 are connected to the control means 509.
[First Embodiment]
The sequence of this embodiment executed by the control unit 509 will be described with reference to FIGS. 6 and 7. 6 and 7 show the sequence of this embodiment. In the present embodiment, when the focal length is switched by the operation dial 110, the set value is switched for each operation of the rotation angle A degree of the operation dial 110. On the other hand, when the aperture value is switched by the operation dial 110, the setting value is switched every time the operation dial 110 is operated at a rotation angle of 2A.

  In step S601, the control unit 509 determines whether or not the main power switch 106 is turned on. If ON is detected, the process proceeds to step S602. If ON is not detected, the process of step S601 is repeated.

  In step S <b> 602, the control unit 509 confirms the photographing function stored in the storage unit 506.

  In step S603, the control unit 509 determines whether the shooting function has been changed by the dial function setting unit 109 from the shooting function confirmed in step S602. If the shooting function has been changed, the process proceeds to step S604. If the shooting function has not been changed, the process proceeds to step S607. In this embodiment, the user can set a “focus mode” in which a focal length can be selected and an “aperture mode” in which a shutter aperture value can be selected.

  In step S604, the control unit 509 determines whether or not the photographing function is set to the “focus mode”. If the shooting function is set to “focus mode”, the process proceeds to step S605. If the shooting function is not set to “focus mode”, the process proceeds to step S606.

  In step S605, the control unit 509 causes the storage unit 506 to store the photographing function as the “focus mode”.

  In step S607, the control unit 509 determines whether or not a change in the detection signal of PR1 output from the position detection unit 116 is detected within a predetermined time. If a change in the detection signal is detected, that is, if the operation of the operation dial 110 is started by the user, the process proceeds to step S619, and if a change in the detection signal is not detected, the process proceeds to step S608.

  In step S619, the control unit 509 determines whether a detection signal (switching signal) indicating switching of HI / LO from PR1 is received. If the switching signal is received, the process proceeds to step S620. If the HI / LO switching position is not detected, the process proceeds to step S608. The switching signal is a detection signal that is output when a switching from HI to LO is detected in the forward rotation of the operation dial 110, and when a switching from LO to HI is detected in the reverse rotation.

  In step S620, the control unit 509 starts measuring the elapsed time T of the operation of the operation dial 110 using the time when the switching signal is received as the measurement start time.

  In step S621, the control unit 509 determines whether the photographing function stored in the storage unit 506 is the “aperture mode”. When the photographing function is “aperture mode”, the process proceeds to step S701. When the photographing function is not “aperture mode”, that is, when the photographing function is “focus mode”, the process proceeds to step S622.

  In step S622, the control unit 509 accumulates the switching frequency C of HI / LO switching.

  In step S623, the control unit 509 determines whether or not the number of switching times C is 1. If the switching count C is 1, the process proceeds to step S624. If the switching count C is not 1, that is, if the next switching is detected after the HI / LO switching has already been detected, the process proceeds to step S629.

  In step S624, the control unit 509 stores rotational phase information representing the combination of PR1 and PR2 HI / LO at the operation position of the operation dial 110 stored in the storage unit 506, and changes in the detection signals of PR1 and PR2. Compare. Thereby, the operation direction of the operation dial 110 can be detected.

  In step S625, the control unit 509 causes the storage unit 506 to store the operation direction detected in step S624.

  In step S626, the control unit 509 switches the focal length setting value for one stage by driving the focal point driving unit 505 in the focal length adjustment direction that matches the operation direction of the operation dial 110. The switched setting value is stored in the storage unit 506.

  In step S627, the control unit 509 drives the vibration unit 117 to increase the amplitude so that the vibration amplitude increases to the amplitude A1.

  In step S628, the control unit 509 stores the drive setting of the vibration unit 117 in the storage unit 506.

  In step S629, the control unit 509 determines whether the current operation direction of the operation dial 110 matches the operation direction stored in the storage unit 506. If the operation directions match, the process proceeds to step S630. If the operation directions do not match, the process proceeds to step S633.

  In step S630, the control unit 509 switches the focal length setting value for one stage by driving the focal point driving unit 505 in the focal length adjustment direction that matches the rotation direction of the operation dial 110. The switched setting value is stored in the storage unit 506.

  In step S631, the control means 509 determines the switching time interval Ta.

  In step S632, the control unit 509 changes the number of switching times C to 1.

  In step S633, the control unit 509 changes the number of switching times C to zero.

  In step S634, the control unit 509 deletes the elapsed time T.

  In step S608, the control unit 509 determines whether the elapsed time T is less than the predetermined time T1. When the elapsed time T is smaller than the predetermined time T1, the process proceeds to step S609, and when the elapsed time T is larger than the predetermined time T1, the process proceeds to step S612. When the elapsed time T is equal to the predetermined time T1, which step to proceed to can be arbitrarily set. Note that when the measurement of the elapsed time T is not started, the elapsed time T is zero.

  In step S609, the control unit 509 can feel the vibration A of the current vibration by the vibration unit 117 when the operator touches the operation dial 110, the front cover 101, or the like with a hand or a finger. It is determined whether or not it is equal to a predetermined amplitude A1 that can be sensed by humans. If the amplitude A is equal to the amplitude A1, the process proceeds to step S610. If the amplitude A is not equal to the amplitude A1, the process proceeds to step S602.

  In step S610, the control unit 509 drives the vibration unit 117 to maintain the amplitude so that the current vibration amplitude A1 is maintained.

  In step S <b> 611, the control unit 509 stores the drive setting of the vibration unit 117 in the storage unit 506.

  In step S612, the control unit 509 determines whether or not the elapsed time T is less than a predetermined time T2 that is greater than the predetermined time T1. If the elapsed time T is smaller than the predetermined time T2, the process proceeds to step S613. If the elapsed time T is larger than the predetermined time T2, the process proceeds to step S635. When the elapsed time T is equal to the predetermined time T2, which step to proceed to can be arbitrarily set.

  In step S613, the control unit 509 determines whether the amplitude A of the current vibration by the vibration unit 117 is equal to the amplitude A1. If the amplitude A is equal to the amplitude A1, the process proceeds to step S614. If the amplitude A is not equal to the amplitude A1, the process proceeds to step S602.

  In step S614, the control unit 509 determines that the operation speed of the operation dial 110 is extremely slow or is equal to being stopped, and drives the vibration unit 117 to decrease the amplitude so that the amplitude of vibration decreases to the amplitude lower limit value. . The amplitude lower limit is normally set to 0.

  In step S615, the control unit 509 stores the drive setting of the vibration unit 117 in the storage unit 506.

  In step S635, the control unit 509 determines that the operation dial 110 is equal to being stopped, and drives the vibration unit 117 to decrease the amplitude so that the amplitude of the vibration is reduced to 0 in order to stop the vibration.

  In step S636, the control unit 509 causes the storage unit 506 to store the drive setting of the vibration unit 117.

  In step S616, the control unit 509 erases the elapsed time T.

  In step S617, the control unit 509 determines whether or not the main power switch 106 is detected to be off. If OFF is detected, this sequence is terminated. If OFF is not detected, the process proceeds to step S602.

  In step S701, the control unit 509 accumulates the number of switching times C.

  In step S <b> 702, the control unit 509 determines whether the number of switching times C is 1. If the switching count C is 1, the process proceeds to step S703. If the switching count C is not 1, the process proceeds to step S708.

  In step S703, the control unit 509 stores rotational phase information representing the combination of PR1 and PR2 HI / LO at the operation position of the operation dial 110 stored in the storage unit 506, and changes in the detection signals of PR1 and PR2.

Thereby, it is possible to shorten the time until the amplitude is increased to the amplitude A1 during the amplitude increase driving. The amplitude A2 may be an amplitude that cannot be felt or may be an amplitude that can be felt. When the amplitude A2 is an amplitude that can be sensed by humans, the vibration of the amplitude A2 is continued while it is determined that the operation dial 110 is being operated, so that the user recognizes his / her operation by the digital camera 100.

  When switching of HI / LO is detected at time T11 and the switching time interval Tm (= T11−T10) is equal to or greater than the predetermined time T1 and less than the predetermined time T2, the operation speed of the operation dial 110 is determined to be “slow”. Is done. The control unit 509 switches the focal length setting value by one step and simultaneously drives the vibration unit 117 to increase the frequency so that the amplitude frequency increases to the frequency F1. Since the frequency increasing drive is performed so as to change from the frequency F2 to the frequency F1, the time required to reach the frequency F1 can be made shorter than the time required to reach the frequency F1 from the frequency 0. Therefore, the time difference from the switching of the focal length setting value to the occurrence of the vibration of the frequency F1 can be reduced.

  When switching between HI / LO is detected at time T12 and the switching time interval Tn (= T12−T11) is less than the predetermined time T1, the operation speed of the operation dial 110 is determined to be “fast”. In the frequency increase drive by the vibration means 117 started at time T11, the time required for the vibration frequency to reach the frequency F1 is insufficient, so the vibration frequency does not reach the frequency F1. In the control of the present embodiment, when the HI / LO switching is detected, the control unit 509 switches the focal length setting value by one step. In addition, when the vibration unit 117 is in the frequency increase drive, the control unit 509 causes the vibration unit 117 to continue the frequency increase drive until the frequency reaches the frequency F1.

  When switching of HI / LO is detected at time T13 and the switching time interval Tn (= T13−T12) is less than the predetermined time T1, the operation speed of the operation dial 110 is determined to be “fast”. The control unit 509 switches the focal length setting value by one step. In addition, when the vibration frequency of the vibration unit 117 is the frequency F1, the control unit 509 drives the vibration unit 117 so that the current frequency F1 is maintained. On the other hand, when the vibration frequency of the vibration unit 117 is not the frequency F1, the control unit 509 drives the vibration unit 117 to increase the frequency so that the vibration frequency increases to the frequency F1. Therefore, even when the operation speed of the operation dial 110 is “fast” continuously, the frequency of vibration by the vibration means 117 is likely to maintain the frequency F1.

  When switching of HI / LO is detected at time T14 and the switching time interval Tn (= T14−T13) is less than the predetermined time T1, the operation speed of the operation dial 110 is determined to be “fast”. The control means 509 switches the focal length setting value by one step and simultaneously drives the vibration means 117 so that the current frequency F1 is maintained because the vibration frequency of the vibration means 117 is the frequency F1. .

  When the predetermined time T1 elapses without detecting the switching of HI / LO from time T14, the control means 509 drives the vibration means 117 to decrease the frequency so that the vibration frequency decreases to the frequency F2, which is the frequency lower limit value. Let When the frequency reaches the frequency F2, the control unit 509 drives the vibration unit 117 to maintain the frequency at which the current frequency F2 is maintained.

  If the predetermined time T2 elapses without detecting the HI / LO switching at time T15, it is determined that the operation dial 110 is equal to being stopped. The control unit 509 stops measuring the elapsed time, sets the frequency lower limit value from the frequency F2 to the frequency 0, and drives the vibration unit 117 to decrease the frequency so that the vibration frequency decreases to the frequency lower limit value.

  When the digital camera 100 recognizes that the operation dial 110 is equal to being stopped, the frequency of vibration by the vibration means 117 becomes 0, so that the user can feel at ease that his / her stop operation is recognized by the digital camera 100. There is.

  In the present embodiment, the frequency lower limit value is a fixed value, but it may be changed according to the switching time interval. FIG. 18 is an example of a setting table of frequency lower limit values. The setting table is stored in the storage unit 506 in advance. The control means 509 selects a frequency lower limit value (0 <F4 <F5 <F6 ≦ F1) from the setting table based on the operation information of the operation dial 110 and the switching time interval.

  As described in the first embodiment, depending on the function assigned to the operation dial 110, the presence / absence of vibration generation or the setting value switching is determined according to the number of times of switching between HI / LO. You may decide.

  In the first to fourth embodiments, “diaphragm mode” and “focus mode” have been described as functions that can be selected by the dial function setting means 109, but the present invention is not limited to this. The dial function setting means 109 can be used to change the functions of the digital camera 100, such as the selection of the shutter speed during shooting, the selection of the zoom position of the taking lens unit 105, and the ISO sensitivity adjustment value of the imaging means 504. It is good.

  Further, in the present embodiment, the operation speed of the operation dial 110 is calculated from the time required for the operation of the operation dial 110 by a predetermined distance using the time detection unit incorporated in the position detection unit 116 and the control unit 509. The present invention is not limited to this. Other methods may be used as long as the operation speed of the operation dial 110 and the elapsed time of the presence / absence of the operation can be known directly or indirectly.

  In the first to third embodiments, an example of detecting the amplitude or changing the amplitude is shown. In the fourth embodiment, an example of detecting the frequency or changing the frequency is individually shown. The detection and control of amplitude and frequency may be performed together.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
