It is comprised by the member of.

  The display unit 17 inputs and outputs signals at the port P6, and displays first information IN1 and second information IN2 as information relating to composition adjustment on the through image (see FIGS. 8 and 9). The first information IN1 illustrates the positional relationship of the movable portion 30a with respect to the movable range, and when the movable portion 30a hits a frame indicating the outer shape of the movable range, the hit state is highlighted. The second information IN2 illustrates the tilt state of the imaging device 1 and the rotation state of the movable unit 30a.

  Specifically, the first information IN1 includes a first frame F1 that schematically represents the outer shape of the movable part 30a and a second frame F2 that schematically represents the movable range of the movable part 30a. When the movable portion 30a can rotate and move in accordance with the rotation amount α, the two sides of the rectangle that forms the outer shape of the first frame F1 are parallel to the two sides of the rectangle that form the outer shape of the second frame F2. In addition, the first frame F1 and the second frame F2 are displayed in a state where the first frame F1 is disposed at the center of the second frame F2 (see FIGS. 8 and 9).

  When the movable part 30a cannot rotate in correspondence with the rotation amount α, the first frame F1 is emphasized in an inclined state, and a part of the rectangular vertex constituting the outer shape of the first frame F1 is the first part. The first frame F1 and the second frame F2 are displayed in a state in which at least one of the sides constituting the outer shape of the second frame F2 is emphasized in contact with the two frames F2 (see FIG. 10). When the movable portion 30a cannot perform lateral shift movement corresponding to the lateral movement amount H, a state in which at least one of the two sides parallel to the second direction y of the rectangle constituting the outer shape of the second frame F2 is emphasized Thus, the first frame F1 and the second frame F2 are displayed (see FIG. 11). In a case where the movable portion 30a cannot perform vertical shift movement corresponding to the vertical movement amount V, a state in which at least one of two sides parallel to the first direction x of the rectangle constituting the outer shape of the second frame F2 is emphasized Thus, the first frame F1 and the second frame F2 are displayed (see FIG. 12).

  As the first information IN1, the first frame F1 and the second frame F2 are displayed in different display states depending on whether they can move or not, thereby displaying the state of the movable portion 30a with respect to the movable range, In particular, it can be easily grasped whether or not it is immovable. Further, the warning display regarding the rotational movement uses the first frame F1, while the warning display regarding the horizontal shift movement and the vertical shift movement uses the second frame F2, so that the type of movement being warned can be easily grasped.

Accordingly, the image is displayed while being rotated around the optical axis LL. The camera tilt angle Kθ is indicated by an angle formed by the horizontal axis HX and the first direction axis AX (see the outer hatched portion in FIGS. 13 to 15). The rotation amount α is indicated by an angle formed by the first direction axis AX and the movable portion inclination axis LVX (see the inner hatched portion in FIGS. 14 and 15). The tilt angle around the optical axis LL with respect to the horizontal plane perpendicular to the gravitational direction of the movable portion 30a (movable portion tilt angle LVL) is indicated by the angle formed by the horizontal axis HX and the movable portion tilt axis LVX (LVL = Kθ + α, FIG. 16). (Refer to (7)).

  However, the first information IN1 and the second information IN2 may be displayed not only on the through image but also on a separately provided display device.

  The photographing lens 67 is an interchangeable lens of the imaging device 1 and is connected to the port P8 of the CPU 21, and the lens information recorded in the lens ROM or the like built in the photographing lens 67 is turned on. Is output to the CPU 21 at a time. The DSP 19 is connected to the port P9 of the CPU 21 and the imaging unit 39a, and performs arithmetic processing such as image processing on an image signal obtained by imaging in the imaging unit 39a based on an instruction from the CPU 21.

  The CPU 21 is a control unit that controls the movement of the movable unit 30a when performing control of each unit related to imaging, particularly when performing composition adjustment.

  The AE unit 23 performs a photometric operation of the subject to calculate an exposure value, and calculates an aperture value and an exposure time necessary for photographing based on the exposure value. The AF unit 24 performs distance measurement, and performs focus adjustment by displacing the photographing lens 67 in the optical axis direction based on the distance measurement result. The AE unit 23 and the AF unit 24 input and output signals at ports P4 and P5, respectively.

  The composition adjustment device of the image pickup apparatus 1, that is, the part relating to the composition adjustment processing includes the composition adjustment on / off button 14, the composition adjustment key 16, the display unit 17, the CPU 21, the tilt detection unit 25, the driver circuit 29 for driving, the composition adjustment unit 30, and the magnetic field. A Hall element signal processing circuit 45 is provided as a signal processing circuit for the change detection element.

  When the composition adjustment on / off button 14 is pressed, the composition adjustment switch 14a is turned on, and the operation of the composition adjustment key 16 is enabled. In this case, independently of other operations such as photometry, the inclination detection unit 25 and the composition adjustment unit 30 are driven at regular intervals to perform composition adjustment processing. The composition adjustment parameter CP is set to 1 in the case of the composition adjustment mode in which the composition adjustment switch 14a is turned on, and the composition adjustment parameter CP is set to 0 in the case of the composition adjustment mode in which the composition adjustment switch 14a is not turned off. Is done. In the present embodiment, this fixed time will be described as 1 ms. The on / off information of the composition adjustment switch 14a is input to the port P14 of the CPU 21 as a 1-bit digital signal.

  Next, the details of the inclination detecting unit 25, the driver circuit 29 for driving, the composition adjusting unit 30, the Hall element signal processing circuit 45, and the input / output relationship with the CPU 21 will be described.

  The inclination detection unit 25 includes an acceleration sensor 26 and first and second amplifiers 28a and 28b. The acceleration sensor 26 detects a first gravitational acceleration component that is a first direction x component (lateral component) of gravity acceleration and a second gravitational acceleration component that is a second direction y component (vertical component) of gravity acceleration. It is a sensor. The first amplifier 28a amplifies the signal related to the first gravitational acceleration component output from the acceleration sensor 26, and outputs an analog signal to the A / D1 of the CPU 21 as the first acceleration ah. The second amplifier 28b amplifies the signal relating to the second gravitational acceleration component output from the acceleration sensor 26, and outputs an analog signal to the A / D2 of the CPU 21 as the second acceleration av.

  The composition adjustment unit 30 is a device that changes the composition by moving the imaging unit 39a to the position S to be moved calculated by the CPU 21 when performing composition adjustment processing (CP = 1). A movable part 30a having a movable area on the xy plane is provided, and a fixed part 30b.

  The power supply to each part of the CPU 21 and the inclination detection unit 25 is started after the Pon switch 11a is turned on (the main power source is turned on). The inclination detection calculation in the inclination detecting unit 25 is started after the Pon switch 11a is turned on (the main power source is turned on).

  The CPU 21 performs A / D conversion on the first and second accelerations ah and av input to the A / D1 and A / D2 (first and second digital acceleration signals Dah and Dav), and removes high-frequency components to remove noise. (Digital low-pass filter processing, first and second digital accelerations Aah, Aav), and an inclination angle (camera inclination angle Kθ) about the optical axis LL with respect to a horizontal plane perpendicular to the gravity direction of the imaging device 1 is obtained (FIG. 16). (See (1)). The tilt angle (camera tilt angle Kθ) is the tilt angle of the image pickup apparatus 1 that varies depending on the holding posture or the like (the tilt degree around the optical axis LL compared to the state held horizontally). In other words, the inclination of the imaging device 1 is represented by an angle formed between a horizontal plane perpendicular to the direction of gravity and the first direction x or an angle formed between the horizontal plane and the second direction y. When the angle between one of the first direction x and the second direction y and the horizontal plane is 0 degree and the angle between the other of the first direction x and the second direction y and the horizontal plane is 90 degrees, the imaging apparatus 1 Is not tilted. Therefore, the tilt detection unit 25 and the CPU 21 have a function of calculating the tilt angle of the imaging device 1.

  The first and second digital accelerations Aah and Aav corresponding to the first and second gravitational acceleration components vary depending on the holding posture of the imaging apparatus 1, and indicate values from −1 to +1. For example, when the imaging device 1 is in the upright lateral position and posture state, that is, when the imaging device 1 is in a horizontal holding state and the upper surface portion of the imaging device 1 faces upward (see FIG. 2). The first digital acceleration Aah is 0, and the second digital acceleration Aav is +1. When the imaging device 1 is in the inverted horizontal position and posture state, that is, when the imaging device 1 is in the horizontal holding state and the bottom surface portion of the imaging device 1 faces upward (see FIG. 3), The first digital acceleration Aah is 0, and the second digital acceleration Aav is -1. When the imaging device 1 is in the first vertical position and posture state, that is, when the imaging device 1 is in the vertical holding state and one of the side surfaces of the imaging device 1 faces upward (see FIG. 4). The first digital acceleration Aah is −1 and the second digital acceleration Aav is 0. When the imaging device 1 is in the second vertical position and posture state, that is, when the imaging device 1 is in the vertical holding state and the other side surface of the imaging device 1 faces upward (see FIG. 5). The first digital acceleration Aah is +1 and the second digital acceleration Aav is 0.

  When the front part of the image pickup apparatus 1 (the side where the taking lens 67 is located) is in the anti-gravity direction or the gravitational direction (up or down), the first and second digital accelerations Aah and Aav are both 0. is there.

When the imaging apparatus 1 is rotated (inclined) by Kθ counterclockwise as viewed from the front from the upright lateral position / posture state (see FIG. 17), the first digital acceleration Aah is −sin (Kθ), 2 The digital acceleration Aav is + cos (Kθ). Therefore, in order to obtain the tilt angle (camera tilt angle Kθ), the first digital acceleration Aah is subjected to arc sine transformation and a negative sign is added, or the second digital acceleration Aav is subjected to arc cosine transformation. I can do it. However, when the absolute value of the tilt angle (Kθ) is very small (close to 0), the amount of change in the sine function is larger than the amount of change in the cosine function. Thus, it is possible to calculate the tilt angle with higher accuracy than the calculation for performing arc cosine transformation (Kθ = −Sin ⁻¹ (Aah), see step S77 in FIG. 27).

When the imaging apparatus 1 is rotated (tilted) by Kθ counterclockwise as viewed from the front from the first vertical position and posture state (see FIG. 18), the first digital acceleration Aah is −cos (Kθ), 2 The digital acceleration Aav is -sin (Kθ). Therefore, in order to obtain the tilt angle (camera tilt angle Kθ), arc cosine transformation is applied to the first digital acceleration Aah and a negative sign is applied, or arc sine conversion is applied to the second digital acceleration Aav and a negative sign is applied. Can be determined by However, when the absolute value of the tilt angle (Kθ) is very small (close to 0), the amount of change in the sine function is larger than the amount of change in the cosine function. Thus, the tilt angle can be calculated with higher accuracy than the calculation for performing arc cosine transformation (Kθ = −Sin ⁻¹ (Aav), see step S73 in FIG. 27).

When the imaging device 1 is rotated (inclined) by Kθ counterclockwise as viewed from the front from the inverted lateral position posture state (see FIG. 19), the first digital acceleration Aah is + sin (Kθ), and the second digital The acceleration Aav is −cos (Kθ). Therefore, in order to obtain the tilt angle (camera tilt angle Kθ), the arc sine conversion is performed on the first digital acceleration Aah, or the arc cosine transform is performed on the second digital acceleration Aav and a negative sign is given. I can do it. However, when the absolute value of the tilt angle (Kθ) is very small (close to 0), the amount of change in the sine function is larger than the amount of change in the cosine function. Thus, it is possible to calculate the tilt angle with higher accuracy than the calculation for performing arc cosine transformation (Kθ = + Sin ⁻¹ (Aah), see step S76 in FIG. 27).

When the imaging device 1 is rotated (inclined) by Kθ counterclockwise as viewed from the front from the second vertical position posture state (see FIG. 20), the first digital acceleration Aah is + cos (Kθ), and the second The digital acceleration Aav is + sin (Kθ). Therefore, the inclination angle (camera inclination angle Kθ) can be obtained by performing arc cosine transformation on the first digital acceleration Aah or arc sine transformation on the second digital acceleration Aav. However, when the absolute value of the tilt angle (Kθ) is very small (close to 0), the amount of change in the sine function is larger than the amount of change in the cosine function. Thus, it is possible to calculate the tilt angle with higher accuracy than the calculation that performs arc cosine transformation (Kθ = + Sin ⁻¹ (Aav), see step S74 in FIG. 27).

The tilt angle, that is, the camera tilt angle Kθ is obtained by performing arc sine transformation on the smaller value of the first digital acceleration Aah and the second digital acceleration Aav and attaching a plus or minus sign (Kθ). = Any one of + Sin ⁻¹ (Aah), −Sin ⁻¹ (Aah), + Sin ⁻¹ (Aav), and −Sin ⁻¹ (Aav)). The sign of the added sign is determined based on the sign of the larger absolute value (whether it is smaller than 0) between the first digital acceleration Aah and the second digital acceleration Aav. Specifically, this will be described later with reference to the flowchart of FIG.

  In the present embodiment, the acceleration detection processing in the first interrupt processing refers to processing in the tilt detection unit 25 and input processing of the first and second accelerations ah and av from the tilt detection unit 25 to the CPU 21. The camera tilt angle Kθ is used to calculate the movable portion tilt angle LVL that is added to the rotation amount α set by the user.

  When the composition adjustment process is performed (CP = 1), the CPU 21 determines the lateral movement amount H of the movable portion 30a based on the operation amount of the right direction key 16a and the left direction key 16b by the user, and the upward direction key 16c. The vertical movement amount V of the movable portion 30a is determined based on the operation amount of the down key 16d, and the rotation amount α is determined based on the operation amounts of the right rotation key 16e and the left rotation key 16f.

  When composition adjustment processing is not performed (CP = 0), the movable part 30a is in the initial state (the movable part 30a is the center of the movable range and the four sides constituting the outer shape of the imaging surface of the imaging element 39a1 are in the first direction x. Alternatively, the horizontal movement amount H, the vertical movement amount V, and the rotation amount α are set so as to be fixed in a state parallel to the second direction y (H = V = α = 0).

  The CPU 21 calculates the position S of the movable portion 30a (the movement position of the drive point of the movable portion 30a) to be moved corresponding to the horizontal movement amount H, the vertical movement amount V, and the rotation amount α ((2 in FIG. 16). ), See steps S57 and S60 in FIG. 26), and after the calculation, move to the position S.

  By using the composition adjustment key 16, the movable portion 30a is moved in the first direction x to perform composition adjustment by horizontal shift movement, and by moving in the second direction y, composition adjustment by vertical shift movement is performed. By performing rotation, composition adjustment is performed by rotational movement. The relationship between the operation of the composition adjustment key 16 and the moving direction of the movable unit 30a is set so that the user can perform without considering the inversion and inversion of the subject image formed on the front part of the imaging device 1. For example, if the movable part 30a is moved rightward when viewed from the back by a lateral shift movement, the composition (subject) moves to the left than before the movement, and the movable part 30a is moved upward by a vertical shift movement. Then, the composition (subject) moves downward as compared to before the movement. If the movable part 30a is rotated clockwise as viewed from the back by rotational movement, the composition (subject) also rotates clockwise.

  That is, the movable portion 30a is moved so that the direction indicated by each direction key of the composition adjustment key 16 matches the moving direction of the display image on the display portion 17. Specifically, when the composition adjustment key 16 receives an instruction to move in any of the up / down / left / right directions, the CPU 21 moves the movable portion 30a in a direction opposite to the direction instructed when viewed from the back side. When receiving the rotational movement instruction, the CPU 21 rotates the movable portion 30a in the same direction as the instructed rotational direction when viewed from the back side. For this reason, the composition can be moved in accordance with the direction in which the composition is desired to be moved.

  Thereby, even when the imaging device 1 is fixed with a tripod or the like, the change of the composition accompanying the movement of the movable portion 30a is confirmed by looking at the through image displayed on the display unit 17 without moving the imaging device 1. It becomes possible to adjust the composition. In addition, since the composition before and after the adjustment can be confirmed with the through image displayed on the display unit 17, it is possible to adjust the composition according to the intention of the user while viewing the through image.

  In FIG. 8, the image is taken in a state where the vehicle is at the left end and the head is directed diagonally upward to the right. Here, the left key 16b is operated to move the movable part 30a to the right when viewed from the back, the downward key 16d is operated to move the movable part 30a upward, and the right rotation key 16e is By operating and rotating the movable unit 30a clockwise when viewed from the back (counterclockwise when viewed from the front), the vehicle is imaged in a horizontal state near the center of the image sensor 39a1, as shown in FIG. Is done.

  In the present embodiment, only the movable part 30a provided inside the imaging apparatus 1 and including the imaging element 39a1 is moved on a plane (on the xy plane) perpendicular to the optical axis LL, so that the imaging apparatus 1 is used for composition adjustment. There is no need to move. For this reason, an apparatus does not enlarge.

  However, since the movable part 30a cannot move beyond the movable range, the position S is calculated by using the movable part based on the lateral movement amount H, the longitudinal movement amount V, and the rotation amount α as described later. The relationship between the movement amount of 30a and the movable range is considered.

  The driving point for moving the movable part 30a in the first direction x is set as a lateral driving point DPx, and the driving points for moving and rotating in the second direction y are set as first vertical driving points DPyl and DPyr ( (Refer FIG. 21, FIG. 22). The lateral drive point DPx is set at a position close to the lateral hall element hh10 in that a force is applied by a coil (lateral coil 31a) used for driving the movable portion 30a in the first direction x. The first vertical driving point DPyl is close to the first vertical hall element hv1 in that a force is applied by a coil (first vertical coil 32a1) used for driving the movable portion 30a in the second direction y. Set to position. The second vertical driving point DPyr is close to the second vertical hall element hv2 in that a force is applied by a coil (second vertical coil 32a2) used for driving the movable portion 30a in the second direction y. Set to position.

  The movement position of the lateral drive point DPx (the movement amount in the first direction x with respect to the position of the lateral drive point DPx in the initial state when the composition adjustment process is started) Sx is the rotation amount α, the lateral movement amount H, and Is calculated based on Specifically, the lateral drive point DPx is moved by the first lateral shift amount SHX1 in the first direction x corresponding to the rotation amount α (SHX1 = Lx × cos (θx + α) −Lx × cos ( θx)). Lx is a distance from the rotation center O of the imaging surface of the image sensor 39a1 to the lateral drive point DPx, and θx is formed by a line connecting the lateral drive point DPx and the rotation center O in the initial state and the first direction x. It is an angle, and is a constant determined in advance by design (see FIG. 22). Corresponding to the lateral movement amount H, the lateral driving point DPx is moved in the first direction x by the second lateral shift amount SHX2 (SHX2 = H). Accordingly, the movement position Sx of the lateral drive point DPx is represented by the sum of the first lateral shift amount SHX1 and the second lateral shift amount SHX2 (Sx = SHX1 + SHX2).

  The movement position of the first vertical driving point DPyl (the movement amount in the second direction y with respect to the position of the first vertical driving point DPyl in the initial state) Syl is calculated based on the vertical movement amount V and the rotation amount α. The Specifically, corresponding to the rotation amount α, the first vertical drive point DPyl is moved in the second direction y by the first vertical shift amount SHY1 (SHY1 = Lyl × cos (θyl−α) − Lyl × cos (θyl)). Lyl is a distance from the rotation center O to the first vertical driving point DPyl, and θyl is an angle formed by a line connecting the first vertical driving point DPyl and the rotation center O in the initial state and the second direction y. , A constant determined in advance by design. Corresponding to the vertical movement amount V, the first vertical driving point DPyl is moved in the second direction y by the second vertical shift amount SHY2 (SHY2 = V). Accordingly, the movement position Syl of the first vertical driving point DPyl is represented by the sum of the first vertical shift amount SHY1 and the second vertical shift amount SHY2 (Syl = SHY1 + SHY2).

  The movement position of the second vertical driving point DPyr (the movement amount in the second direction y with respect to the position of the second vertical driving point DPyr in the initial state) Syr is calculated based on the vertical movement amount V and the rotation amount α. The Specifically, the second vertical driving point DPyr is moved by the third vertical shift amount SHY3 in the second direction y corresponding to the rotation amount α (SHY3 = Lyr × cos (θyr + α) −Lyr × cos (θyr)). Lyr is a distance from the rotation center O to the second vertical driving point DPyr, and θyr is an angle formed by a line connecting the second vertical driving point DPyr and the rotation center O in the initial state and the second direction y. , A constant determined in advance by design. Corresponding to the vertical movement amount V, the second vertical driving point DPyr is moved in the second direction y by the fourth vertical shift amount SHY4 (SHY4 = V). Therefore, the movement position Syr of the second vertical driving point DPyr is represented by the sum of the third vertical shift amount SHY3 and the fourth vertical shift amount SHY4 (Syr = SHY3 + SHY4).

  The horizontal drive point DPx is moved in the first direction x by the first horizontal shift amount SHX1 corresponding to the rotation amount α, and the first vertical drive point DPyl is moved in the second direction y by the first vertical shift amount SHY1. When the movable portion 30a is rotated by the rotation amount α by moving the third vertical drive point DPyr in the second direction y by the third vertical shift amount SHY3, an arbitrary point P of the movable portion 30a is obtained. The amount of movement in the first direction x (for example, the vertex of the rectangle (or square) constituting the imaging surface of the image sensor 39a1) is represented by the first amount of movement Rx (Rx = r × sin (B + | α |)). −r × sinB (see FIG. 23), the movement amount in the second direction y is represented by the second movement amount Ry (Ry = r × sin (A + | α |) −r × sinA, see FIG. 24). r is the distance between the rotation center O of the imaging surface and the point P, and the angle B is the angle formed by the line segment connecting the rotation center O and the point P and the second direction y when the movable part 30a is in the initial state. The angle A is an angle formed by a line segment connecting the rotation center O and the point P and the first direction x when the movable part 30a is in an initial state, and these are constants obtained in advance by design.

  The movement position Sx of the lateral drive point DPx is adjusted (restricted) so that the movement of the movable part 30a in the first direction x based on the lateral movement amount H and the rotation amount α is within the movable range of the movable part 30a. Is done. Similarly, the movement position Syl of the first vertical driving point DPyl is set so that the movement in the second direction y of the movable part 30a based on the vertical movement amount V and the rotation amount α is within the movable range of the movable part 30a. , And the movement position Syr of the second vertical driving point DPyr is adjusted (restricted).

  Specifically, the CPU 21 determines whether or not the absolute value of the first movement amount Rx exceeds the first lateral movement amount Tsx indicating the movable amount of the movable part 30a in the first direction x by the rotation, and the second It is determined whether or not the absolute value of the movement amount Ry exceeds a first vertical movement amount Tsy indicating a movable amount of the movable part 30a in the second direction y by rotation. The first lateral movement amount Tsx is represented by the sum of the difference between the second lateral movement amount Ksx and the absolute value of the lateral movement amount H and the absolute value of the first movement amount Rx (Tsx = (Ksx− | H |) + | Rx |). The first vertical movement amount Tsy is represented by the sum of the difference between the second vertical movement amount Ksy and the absolute value of the vertical movement amount V and the absolute value of the second movement amount Ry (Tsy = (Ksy− | V |) + | Ry |).

  The absolute value of the first movement amount Rx is larger than the first lateral movement amount Tsx (Tsx <| Rx |), or the absolute value of the second movement amount Ry is larger than the first vertical movement amount Tsy (Tsy < In the case of | Ry |), the horizontal shift movement is performed corresponding to the horizontal movement amount H and the vertical shift movement is performed corresponding to the vertical movement amount V, and then the movable portion 30a is rotated by the rotation amount α. In this case, it is determined that a part of the movable part 30a hits a frame indicating the outer shape of the movable range of the movable part 30a, and the first horizontal shift amount SHX1, the first vertical shift amount SHY1, corresponding to the rotation amount α, The third rotational shift amount SHY3 is not recalculated, and the previous rotational movement state is maintained.

  In this case, the CPU 21 displays a warning indicating that the rotational movement corresponding to the rotation amount α cannot be performed as the first information IN1 on the through image. Specifically, when the rotation amount α is less than 0, the CPU 21 determines that the counterclockwise rotational movement is not possible when viewed from the back, and emphasizes the first frame F1 by tilting it to the lower left (see FIG. 10). , See step S108 of FIG. 29). When the rotation amount α is equal to or greater than 0, the CPU 21 determines that the clockwise rotation cannot be seen from the back, and emphasizes the first frame F1 by tilting it to the lower right (see step S107 in FIG. 29). ).

  Further, when the CPU 21 determines that the counterclockwise rotational movement as viewed from the rear side cannot be performed, the backlight of the left rotation key 16f is turned on, and the composition adjustment key 16 other than the left rotation key 16f is operated. Unless the state where the rotational movement cannot be performed is cancelled, it is notified that the operation of the left rotation key 16f is invalid. Further, when the CPU 21 determines that it cannot rotate clockwise as viewed from the back, the backlight of the right rotation key 16e is turned on, and the composition adjustment key 16 other than the right rotation key 16e is operated, Unless the state where the rotational movement cannot be performed is cancelled, it is notified that the operation of the right rotation key 16e is invalid (see FIG. 7). FIG. 7 shows a state where the backlight of the right rotation key 16e is lit in the hatched portion.

  The absolute value of the first movement amount Rx is equal to or less than the first lateral movement amount Tsx (Tsx ≧ | Rx |), and the absolute value of the second movement amount Ry is equal to or less than the first vertical movement amount Tsy (Tsy ≧ | In the case of Ry |), the horizontal shift movement is performed corresponding to the horizontal movement amount H and the vertical shift movement is performed corresponding to the vertical movement amount V, and then the movable portion 30a is rotated by the rotation amount α. Even if it makes it, it will judge that the movable part 30a does not hit the frame which shows the external shape of the movable range of the movable part 30a, 1st horizontal direction shift amount SHX1, 1st vertical direction shift amount SHY1 corresponding to rotation amount (alpha), and The third vertical shift amount SHY3 is recalculated (see step S103 in FIG. 29), the horizontal drive point DPx is moved in the first direction x by the first horizontal shift amount SHX1, and the first vertical shift amount SHY1. Only the first vertical driving point DPyl is moved in the second direction y. And the second vertical driving point DPyr is moved in the second direction y by the third vertical shift amount SHY3. In this case, the first information IN1 is displayed on the through image without performing the enhancement with the first frame F1 inclined (see FIGS. 8, 9, 11, 12 and S105 in FIG. 29). ).

  Further, the CPU 21 illustrates the tilt state (camera tilt angle Kθ) of the imaging device 1 and the tilt state (rotation amount α) of the movable unit 30a as the second information IN2 on the through image displayed on the display unit 17. . This makes it possible to objectively grasp the camera tilt angle Kθ, the rotation amount α, and the movable portion tilt angle LVL (= Kθ + α) added together. 9 and 15 illustrate, as an example, two rectangular sides that form the outer shape of the imaging surface of the imaging element 39a by setting the rotation amount α so that the camera tilt angle Kθ is opposite in polarity and the absolute values are equal. Is parallel to the horizontal line and the remaining two sides are perpendicular to the horizontal line (LVL = Kθ + α = 0).

  Further, the CPU 21 determines whether or not the absolute value of the lateral movement amount H exceeds the second lateral movement amount Ksx indicating the movable amount of the movable part 30a in the first direction x by the lateral shift, and the vertical movement amount V. It is determined whether or not the absolute value exceeds the second vertical movement amount Ksy indicating the movable amount of the movable portion 30a in the second direction y due to the vertical shift. The second lateral movement amount Ksx is represented by the sum of the difference between the first lateral movement amount Tsx and the absolute value of the first movement amount Rx and the absolute value of the lateral movement amount H (Ksx = (Tsx− | Rx |) + | H |). The second vertical movement amount Ksy is represented by the sum of the difference between the first vertical movement amount Tsy and the absolute value of the second movement amount Ry and the absolute value of the vertical movement amount V (Ksy = (Tsy− | Ry |) + | V |).

  When the absolute value of the lateral movement amount H is larger than the second lateral movement amount Ksx (Ksx <| H |), the rotational movement is performed corresponding to the rotational amount α and the vertical movement amount V is corresponded. When the movable portion 30a is laterally shifted by the lateral movement amount H after performing the vertical shift movement, it is determined that a part of the movable portion 30a hits a frame indicating the outer shape of the movable range of the movable portion 30a. The second horizontal shift amount SHX2 corresponding to the horizontal movement amount H is not recalculated, and the previous horizontal shift movement state is maintained.

  In this case, the CPU 21 displays a warning indicating that the lateral shift movement corresponding to the lateral movement amount H cannot be performed as the first information IN1 on the through image. Specifically, when the lateral movement amount H is less than 0, the CPU 21 cannot laterally shift the movable unit 30a in the right direction when viewed from the back, that is, the composition can be moved in the left direction. It is determined that this is not possible, and the left side of the second frame F2 is emphasized (see FIG. 11 and step S114 in FIG. 29). When the lateral movement amount H is 0 or more, the CPU 21 determines that the movable portion 30a cannot be laterally shifted to the left when viewed from the back, that is, the composition cannot be moved to the right. The right side of the second frame F2 is emphasized (see step S115 in FIG. 29).

  Further, when the CPU 21 determines that the movable portion 30a cannot be laterally shifted in the right direction when viewed from the back, the backlight of the left direction key 16b is turned on, and the composition adjustment key other than the left direction key 16b is turned on. 16 is informed that the operation of the left direction key 16b is invalid unless the state where the lateral shift movement cannot be performed is released. When the CPU 21 determines that the leftward shift of the movable portion 30a is not possible when viewed from the back side, the CPU 21 turns on the backlight of the right key 16a and the composition adjustment key other than the right key 16a. Unless the state in which the lateral shift movement cannot be performed is released by operating 16, the operation of the right direction key 16a is notified to be invalid.

  When the absolute value of the lateral movement amount H is equal to or smaller than the second lateral movement amount Ksx (Ksx ≧ | H |), the rotational movement is performed in accordance with the rotation amount α and the vertical movement amount V is supported. Even if the movable portion 30a is laterally shifted by the lateral movement amount H after performing the vertical shift movement, it is determined that the movable portion 30a does not hit the frame indicating the outer shape of the movable range of the movable portion 30a. The second lateral shift amount SHX2 corresponding to the travel amount H is recalculated (see step S110 in FIG. 29), and the lateral drive point DPx is moved in the first direction x by the second lateral shift amount SHX2. In this case, the first information IN1 is displayed on the through image without emphasizing the right side and the left side of the second frame F2 (see FIGS. 8, 9, 12 and S112 in FIG. 29). ).

  When the absolute value of the vertical movement amount V is larger than the second vertical movement amount Ksy (Ksy <| V |), the rotational movement is performed according to the rotation amount α and the horizontal movement amount H is corresponded. If the movable portion 30a is vertically shifted by the vertical movement amount V after performing the lateral shift movement, it is determined that a part of the movable portion 30a hits a frame indicating the outer shape of the movable range of the movable portion 30a. The second vertical shift amount SHY2 and the fourth vertical shift amount SHY4 corresponding to the vertical movement amount V are not recalculated, and the previous vertical shift movement state is maintained.

  In this case, the CPU 21 displays a warning indicating that the vertical shift movement corresponding to the vertical movement amount V cannot be performed as the first information IN1 on the through image. Specifically, when the vertical movement amount V is less than 0, the CPU 21 determines that the movable unit 30a cannot be shifted vertically and moved, that is, the composition cannot be moved downward. Then, the lower side portion of the second frame F2 is emphasized (see FIG. 12, see step S121 in FIG. 29). When the vertical movement amount V is equal to or greater than 0, the CPU 21 determines that the movable portion 30a cannot be vertically shifted downward, that is, the composition cannot be moved upward, and the second frame The upper side of F2 is emphasized (see step S122 in FIG. 29).

  Further, when the CPU 21 determines that the movable portion 30a cannot be vertically shifted upward, the CPU 21 turns on the backlight of the down key 16d and operates the composition adjustment key 16 other than the down key 16d. Thus, unless the state in which the vertical shift movement cannot be performed is cancelled, it is notified that the operation of the down key 16d is invalid. Further, when the CPU 21 determines that the movable portion 30a cannot be vertically shifted downward, the CPU 21 turns on the backlight of the upward key 16c and operates the composition adjustment key 16 other than the upward key 16c. Thus, unless the state in which the vertical shift movement cannot be performed is cancelled, it is notified that the operation of the up direction key 16c is invalid.

  When the absolute value of the vertical movement amount V is equal to or less than the second vertical movement amount Ksy (Ksy ≧ | V |), the rotational movement is performed in accordance with the rotation amount α and the horizontal movement amount H is supported. Then, even if the movable portion 30a is vertically shifted by the vertical movement amount V, it is determined that the movable portion 30a does not hit the frame indicating the outer shape of the movable range of the movable portion 30a. The second vertical shift amount SHY2 and the fourth vertical shift amount SHY4 corresponding to the movement amount V are recalculated (see step S117 in FIG. 29), and the first vertical drive point DPyl is set by the second vertical shift amount SHY2. Is moved in the second direction y, and the second vertical driving point DPyr is moved in the second direction y by the fourth vertical shift amount SHY4. In this case, the first information IN1 is displayed on the through image without emphasizing the upper side and the lower side of the second frame F2 (see FIG. 8, FIG. 9, FIG. 11, and step S119 of FIG. 29). ).

  Warning display that rotation cannot be performed (highlighted display of first frame F1), warning display that horizontal shift cannot be performed (highlighted display of at least one of right side and left side of second frame F2), and vertical display The warning display indicating that the shift movement cannot be performed (highlighted display of at least one of the upper side and the lower side of the second frame F2) may be performed simultaneously. FIG. 10 shows that the composition is rotated counterclockwise (counterclockwise rotation viewed from the back of the movable part 30a) and the composition is moved downward (upward viewed from the back of the movable part 30a). The first information IN <b> 1 when a warning display indicating that vertical shift movement is not possible is performed.

  These warning displays make it possible to visually recognize the limit of movement of the movable part 30a by composition adjustment. In particular, by turning on the backlight of the keys that cannot be operated, the user can easily know the key for releasing the warning display (turn on the backlight of the keys that can be operated). It may be in the form of

  When the composition adjustment key 16 is configured by a touch panel and is displayed on the display unit 17 or the like, the display state of the keys that cannot be operated may be different from the other keys. Moreover, the form of the warning output of the composition adjustment key 16 may be a form that emits a warning sound or a warning vibration when an inoperable key is operated.

  Further, instead of the keys related to the rotational movement (the right rotation key 16e and the left rotation key 16f) in the composition adjustment key 16, the right direction key 16a, the left direction key 16b, the up direction key 16c, and the down direction key 16d. Alternatively, the rotary dial member 16g may be provided around (see FIG. 31). In this case, when the rotary dial member 16g is rotated clockwise as viewed from the back side, a right rotation switch (not shown) is turned on, and the movable portion 30a is turned on according to the clockwise rotation amount of the rotary dial member 16g. Is rotated clockwise. When the rotary dial member 16g is rotated counterclockwise as viewed from the back side, a left rotation switch (not shown) is turned on, as in the case of pressing the left rotation key 16f, and the counterclockwise rotation of the rotary dial member 16g is turned on. The movable part 30a is rotated counterclockwise according to the amount of rotation.

  Further, in this case, the warning display indicating the non-rotatable state in the clockwise direction is the lighting of the right rotation backlight 16h provided on the right side of the rotary dial member 16g, and the warning display indicating the non-rotatable state in the counterclockwise direction is the rotary dial. This is performed by turning on the left rotation backlight 16i provided on the left side of the member 16g. Accordingly, the rotary dial member 16g is formed of a translucent member that transmits light emitted from the right rotation backlight 16h and the left rotation backlight 16i.

  However, the warning display indicating the clockwise non-rotation state is indicated by turning on the right rotation warning light 16j provided around the rotary dial member 16g and on the right side. It may be performed by turning on the left rotation warning light 16k provided around the dial and on the left side (see FIG. 32).

  Movement of the movable part 30a including the imaging part 39a is performed by an electromagnetic force described later. In order to move the movable portion 30a to the position S, the lateral component of the driving force D that drives the lateral coil 31a via the driving driver circuit 29 is the lateral driving force Dx (lateral PWM duty dx), the first longitudinal The longitudinal component for driving the directional coil 32a1 is a first longitudinal driving force Dyl (first longitudinal PWM duty dyl), and the longitudinal component for driving the second longitudinal coil 32a2 is a second longitudinal driving force Dyr (second). The vertical PWM duty (dyr) is assumed.

  Driving of the movable portion 30a of the composition adjustment unit 30 (including fixing in the initial state) is performed by the CPU 21 from PWM0 to the horizontal PWM duty dx, from PWM1 to the first vertical PWM duty dyl, and from PWM2 to the second vertical PWM duty. This is performed by the electromagnetic force generated by the coil portion and the drive magnet portion included in the drive means via the drive driver circuit 29 that has received the output of dyr (see (3) in FIG. 16). The position P before or after the movement of the movable portion 30a is detected by the Hall element portion 44a and the Hall element signal processing circuit 45. Information on the detected position P includes the A / D3 and A / D3 of the CPU 21 as the horizontal direction detection position signal px as the horizontal direction component and the two first and second vertical direction detection position signals pyl and pyr as the vertical direction component, respectively. It is input to D4 and A / D5 (see (4) in FIG. 16). The lateral direction detection position signal px and the first and second longitudinal direction detection position signals py1, py2 are A / D converted via A / D3, A / D4, A / D5.

  The lateral component of the position P after A / D conversion with respect to the lateral detection position signal px is defined as a lateral component pdx. The vertical components at the position P after A / D conversion with respect to the first and second vertical detection position signals pyl and pyr are first and second vertical components pdyl and pdyr. PID control (lateral driving force Dx, first longitudinal driving force Dyl, second longitudinal driving force Dyl) based on the data of the detected position P (pdx, pdyl, pdyr) and the data of the position S (Sx, Syl, Syr) to be moved Calculation of the directional driving force Dyr) is performed (see (5) in FIG. 16).

  The composition adjustment process, that is, the driving of the movable portion 30a to the position S to be moved by PID control is performed in the composition adjustment mode (CP = 1) in which the composition adjustment switch 14a is turned on. When the composition adjustment parameter CP is 0, the movable portion 30a does not correspond to the composition adjustment processing, PID control for fixing in the initial state is performed, and a rectangle (or square) constituting the outer shape of the imaging surface of the image sensor 39a1. Each of these four sides is moved to the movement center position in a state parallel to either the first direction x or the second direction y (see (6) in FIG. 16).

  The movable portion 30a includes a lateral coil 31a as a driving coil portion, first and second longitudinal coils 32a1 and 32a2, an imaging portion 39a having an imaging device 39a1, and a Hall element portion 44a as a magnetic field change detection element portion ( (Refer FIG. 6, FIG. 21). In the present embodiment, the image sensor 39a1 is described as being a CCD, but another image sensor such as a CMOS may be used.

  The fixed portion 30b includes a transverse magnet 411b, first and second longitudinal magnets 412b1, 412b2, a transverse yoke 431b, and first and second longitudinal yokes 432b1, 432b2 as position detecting and driving magnet portions. .

  The fixed portion 30b sandwiches the movable portion 30a using a ball or the like, and maintains a state in which the movable portion 30a can be moved including rotation within a rectangular region (movable region) on the xy plane.

  In order to perform composition adjustment processing by making the best use of the imaging range of the image sensor 39a1, when the optical axis LL of the photographic lens 67 is in a positional relationship passing near the center (rotation center O) of the image sensor 39a1, the first direction The positional relationship between the movable portion 30a and the fixed portion 30b is set so that the movable portion 30a is positioned at the center of the movable range in both the x and second directions y (at the movement center position). When the Pon switch 11a is turned on in response to pressing of the Pon button 11 and composition adjustment processing is started, that is, in an initial state, the movable portion 30a is positioned at the center of the movable range, and the image sensor 39a1. The positional relationship between the movable portion 30a and the fixed portion 30b so that each of the four sides of the rectangle (or square) constituting the outer shape of the imaging surface is parallel to either the first direction x or the second direction y. After that, composition adjustment processing is started (see step S15 in FIG. 25). The center of the image sensor 39a1 refers to the intersection of two diagonal lines of a rectangle that forms the imaging surface of the image sensor 39a1.

  A transverse coil 31a, first and second longitudinal coils 32a1 and 32a2, and a hall element portion 44a on which a sheet-like and spiral coil pattern is formed are attached to the movable portion 30a. The coil pattern of the transverse coil 31a is such that the transverse drive point DPx in the movable portion 30a including the transverse coil 31a is set in the first direction by the electromagnetic force generated from the current direction of the transverse coil 31a and the direction of the magnetic field of the transverse magnet 411b. In order to move to x, it has a line segment parallel to the second direction y. The coil pattern of the first longitudinal coil 32a1 is the first pattern in the movable part 30a including the first longitudinal coil 32a1 due to the electromagnetic force generated from the current direction of the first longitudinal coil 32a1 and the direction of the magnetic field of the first longitudinal magnet 412b1.

The first and second longitudinal coils 32a1 and 32a2 are arranged so that the distance y is equal in the initial state.

  The horizontal magnet 411b is attached to the movable portion 30a side of the fixed portion 30b so as to face the horizontal coil 31a and the horizontal Hall element hh10.

  The first longitudinal magnet 412b1 is attached to the movable portion 30a side of the fixed portion 30b so as to face the first longitudinal coil 32a1 and the first longitudinal Hall element hv1. The second longitudinal magnet 412b2 is attached to the movable portion 30a side of the fixed portion 30b so as to face the second longitudinal coil 32a2 and the second longitudinal Hall element hv2.

  The lateral magnet 411b is mounted on the fixed portion 30b and the lateral yoke 431b attached to the movable portion 30a side in the third direction z, and the N pole and the S pole are mounted side by side in the first direction x ( Not shown).

N pole and S pole are mounted side by side in two directions y (not shown).

  The lateral yoke 431b is made of a soft magnetic material and is mounted on the fixed portion 30b. The transverse yoke 431b serves to prevent the magnetic field of the transverse magnet 411b from leaking to the surroundings, and the magnetic flux density between the transverse magnet 411b and the transverse coil 31a, and between the transverse magnet 411b and the transverse Hall element hh10. It plays a role to raise.

  The first and second longitudinal yokes 432b1, 432b2 are made of a soft magnetic material and are mounted on the fixed portion 30b. The first longitudinal yoke 432b1 serves to prevent the magnetic field of the first longitudinal magnet 412b1 from leaking to the surroundings, and the first longitudinal magnet 412b1, the first longitudinal coil 32a1, and the first longitudinal magnet 412b1 and the first longitudinal magnet 412b1. It plays the role which raises the magnetic flux density between 1 longitudinal direction hall elements hv1. The second longitudinal yoke 432b2 serves to prevent the magnetic field of the second longitudinal magnet 412b2 from leaking to the surroundings, and the second longitudinal magnet 412b2, the second longitudinal coil 32a2, and the second longitudinal magnet 412b2. It plays a role of increasing the magnetic flux density between the two longitudinal Hall elements hv2.

  The lateral yoke 431b and the first and second longitudinal yokes 432b1 and 432b2 may be separate or integrated.

  The Hall element unit 44a includes three Hall elements that are magnetoelectric conversion elements using the Hall effect, and the current position P (the lateral detection position signal px, the second direction y) of the movable part 30a in the first direction x and the second direction y. 1 and a uniaxial Hall element for detecting a second longitudinal direction detection position signal (pyl, pyr). Among the three Hall elements, the Hall element for position detection in the first direction x is the horizontal Hall element hh10, and the Hall element for position detection in the second direction y is the first and second longitudinal Hall elements hv1 and hv2. .

  The lateral hall element hh10 is mounted on the movable portion 30a as viewed from the third direction z, facing the lateral magnet 411b of the fixed portion 30b, and close to the lateral driving point DPx.

  The transverse hall element hh10 may be arranged side by side with the transverse coil 31a in the second direction y, but is arranged in the winding of the transverse coil 31a, particularly near the center of the first direction x in the winding. (See FIG. 21). The lateral hall element hh10 is stacked with the lateral coil 31a in the third direction z. Since the magnetic field generation region for position detection and the magnetic field generation region for driving the movable part 30a can be shared by the arrangement and lamination in the winding, the horizontal magnet 411b and the horizontal yoke 431b in the second direction y can be used. The length can be shortened.

  Further, since the position (lateral driving point DPx) to which the force for moving the movable portion 30a in the first direction x by the lateral coil 31a is close to the position detection point by the lateral Hall element hh10, high-precision driving is performed. Control can be performed.

  The first vertical hall element hv1 is on the movable portion 30a when viewed from the third direction z, is opposed to the first vertical magnet 412b1 of the fixed portion 30b, and is close to the first vertical drive point DPyl. It is attached. The second vertical hall element hv2 is on the movable part 30a when viewed from the third direction z, is opposed to the second vertical magnet 412b2 of the fixed part 30b, and is close to the second vertical driving point DPyr. It is attached.

  The first vertical hall element hv1 may be arranged side by side with the first vertical coil 32a1 in the first direction x. However, the first vertical hall element hv1 is arranged in the winding of the first vertical coil 32a1 and in particular the second in the winding. It is desirable to arrange in the vicinity of the center in the direction y. The first vertical hall element hv1 is stacked with the first vertical coil 32a1 in the third direction z. Since the magnetic field generation region for position detection and the magnetic field generation region for driving the movable portion 30a can be shared by the arrangement and lamination in the winding, the first longitudinal magnet 412b1 and the first longitudinal yoke 432b1 The length in one direction x can be shortened.

  The second longitudinal hall element hv2 may be arranged side by side with the second longitudinal coil 32a2 in the first direction x. However, the second longitudinal hall element hv2 is arranged in the winding of the second longitudinal coil 32a2 and in particular the second in the winding. It is desirable to arrange in the vicinity of the center in the direction y. The second vertical hall element hv2 is stacked with the second vertical coil 31a2 in the third direction z. By arranging and stacking the windings, the magnetic field generation region for position detection and the magnetic field generation region for driving the movable portion 30a can be shared, so that the second longitudinal magnet 412b2 and the second longitudinal yoke 432b2 The length in one direction x can be shortened.

  Further, a position (first vertical driving point DPyl) to which a force for moving the movable portion 30a in the second direction y by the first vertical coil 32a1 and a position detection point by the first vertical hall element hv1 are close to each other. The position (second vertical driving point DPyr) to which the force for moving the movable portion 30a in the second direction y by the second vertical coil 32a2 is close to the position detection point by the second vertical hall element hv2. This makes it possible to perform highly accurate drive control.

  In order to perform position detection by making the most of the range in which highly accurate position detection can be performed using the linear change amount, the position of the horizontal hall element hh10 in the first direction x is in the initial state of the image sensor 39a1. When the vicinity of the center (rotation center O) is in a positional relationship passing through the optical axis LL, it is desirable that the vicinity of the N pole and S pole of the transverse magnet 411b be in the vicinity of the same distance. Similarly, the position of the first vertical hall element hv1 in the second direction y is the first vertical direction when the vicinity of the center (rotation center O) of the image pickup element 39a1 passes through the optical axis LL in the initial state. It is desirable that the magnet 412b1 be in the vicinity of the same distance from the N pole and S pole. The position of the second vertical hall element hv2 in the second direction y is the initial position of the second vertical magnet 412b2 when the vicinity of the center (rotation center O) of the imaging element 39a1 passes through the optical axis LL. It is desirable to be in the vicinity of the same distance as the N pole and the S pole.

  The hall element signal processing circuit 45 includes first, second, and third hall element signal processing circuits 450, 460, and 470.

  The first hall element signal processing circuit 450 detects the potential difference between the output terminals of the lateral hall element hh10 from the output signal of the lateral hall element hh10, and from this, the first hall element hh10 of the portion of the movable portion 30a where the lateral hall element hh10 is located. A lateral direction detection position signal px specifying the position in the direction x is output to the A / D 3 of the CPU 21. The first hall element signal processing circuit 450 is connected to the lateral hall element hh10 via a flexible substrate (not shown).

  The second hall element signal processing circuit 460 detects the potential difference between the output terminals of the first longitudinal hall element hv1 from the output signal of the first longitudinal hall element hv1, and from this, the first longitudinal hall element hv1 of the movable part 30a is detected. A first vertical direction detection position signal pyl that specifies the position in the second direction y of a certain part is output to the A / D 4 of the CPU 21. The second hall element signal processing circuit 460 is connected to the first longitudinal hall element hv1 via a flexible substrate (not shown).

  The third hall element signal processing circuit 470 detects the potential difference between the output terminals of the second longitudinal hall element hv2 from the output signal of the second longitudinal hall element hv2, and from this, the second longitudinal hall element hv2 of the movable part 30a is detected. A second vertical direction detection position signal pyr that specifies the position of the certain part in the second direction y is output to the A / D 5 of the CPU 21. The third hall element signal processing circuit 470 is connected to the second longitudinal hall element hv2 via a flexible substrate (not shown).

  In the present embodiment, three Hall elements are used to specify the position of the movable part 30a including the rotation angle. The position in the second direction y at two points on the movable part 30a (a point close to the first vertical driving point DPyl and the second vertical driving point DPyr) using two Hall elements among the three Hall elements. Using the remaining one Hall element, the position in the first direction x at one point on the movable portion 30a (a point close to the lateral driving point DPx) is specified. Based on the position information in the second direction y at these two points and the position information in the first direction x at one point, it is possible to specify the position including the rotation angle (tilt) of the movable part 30a.

  Next, the main operation of the imaging apparatus 1 will be described with reference to the flowchart of FIG.

The shift amount SHY2, the third vertical shift amount SHY3, and the fourth vertical shift amount SHY4 are set to 0, and the first horizontal movement amount Tsx and the second horizontal movement amount Ksx are set to the maximum horizontal movement amount HOx. And the first vertical movement amount Tsy and the second vertical movement amount Ksy are set to the vertical maximum movement amount HOy. The maximum horizontal movement amount HOx is the movable amount in the first direction x of the movable portion 30a in the initial state, and the maximum vertical movement amount HOy is the movable amount in the second direction y of the movable portion 30a in the initial state. These are constants obtained in advance by design (see FIGS. 23 and 24).

  In step S13, the first and second interrupt processes are started at regular time intervals (1 ms). Details of the first interrupt process will be described later using the flowcharts of FIGS. 26, 27, and 29, and details of the second interrupt process will be described later using the flowchart of FIG. In step S14, the CPU 21 sets the value of the composition adjustment parameter CP to 0. In step S15, the CPU 21 waits for a time of 300 ms to elapse. Thereafter, the process proceeds to step S16. As a result of the first interrupt process performed during this period, as an initial state, each of the four sides of the rectangle (or square) that constitutes the outer shape of the imaging surface of the imaging element 39a1 is positioned at the center of the movable range 30a. The movable portion 30a is moved so as to be parallel to either the first direction x or the second direction y. Further, communication is performed between the CPU 21 and the photographing lens 67, and lens information is output from the photographing lens 67 to the CPU 21.

  In step S16, the CPU 21 determines whether or not the composition adjustment switch 14a is turned on. If the composition adjustment switch 14a is not turned on, the CPU 21 sets the value of the composition adjustment parameter CP to 0 in step S17. If the composition adjustment switch 14a is on, the CPU 21 sets the value of the composition adjustment parameter CP to 1 in step S18.

  In step S19, CCD charge accumulation, that is, exposure is performed. After the exposure time is over, in step S20, the charge stored in the CCD during the CCD input, that is, within the exposure time is moved. In step S21, communication is performed between the CPU 21 and the DSP 19, image processing is performed based on the transferred electric charge, and the image processed image is displayed on the display unit 17 (through image display).

  In step S22, photometry is performed by the AE unit 23, and the aperture value and exposure time are calculated. In step S23, the AF unit 24 performs distance measurement, and a focusing operation is performed by driving the lens control circuit of the AF unit 24.

  In step S24, the CPU 21 determines whether or not the release switch 13a has been turned on. If the release switch 13a is not turned on, the process returns to step S16 (repeats steps S16 to 23). If the release switch 13a is on, the process proceeds to step S25.

  In step S25, CCD charge accumulation, that is, exposure is performed. After the exposure time is over, in step S26, the charges accumulated in the CCD during the CCD input, that is, within the exposure time, are moved. In step S <b> 27, communication is performed between the CPU 21 and the DSP 19, image processing is performed based on the moved charge, and the image-processed image is stored in the video memory in the imaging apparatus 1. In step S28, the stored image signal is displayed by the display unit 17. Thereafter, the process returns to step S16 (the next imaging operation is enabled).

  Next, the first interrupt process started in step S13 of FIG. 25 and performed at regular time intervals (1 ms) will be described with reference to the flowchart of FIG. When the first interrupt process is started, in step S51, the first and second accelerations ah and av output from the inclination detection unit 25 are A / D converted and input via the A / D1 and A / D2 of the CPU 21. (First and second digital acceleration signals Dah and Dav, acceleration detection processing). The high frequency components of the first and second digital acceleration signals Dah and Dav are cut to remove noise (first and second digital accelerations Aah and Aav, digital low-pass filter processing).

  In step S52, the horizontal direction detection position signal px and the first and second vertical detection position signals pyl and pyr detected by the Hall element unit 44a and calculated by the Hall element signal processing circuit 45 are the A / D3 of the CPU 21, A / D conversion is performed through A / D4 and A / D5, and the current position P (pdx, pdyl, pdyr) is obtained (see (4) in FIG. 16).

  In step S53, the CPU 21 calculates the camera tilt angle Kθ based on the first and second digital accelerations Aah and Aav (see (1) in FIG. 16). Details of the calculation for obtaining the camera tilt angle Kθ will be described later using the flowchart of FIG. In step S54, the CPU 21 determines whether or not the value of the composition adjustment parameter CP is zero. When CP = 0, that is, when the composition adjustment mode is not set, the process proceeds to step S55, and when CP = 1, that is, the composition adjustment mode, the process proceeds to step S58.

  In step S55, the CPU 21 sets the values of the horizontal movement amount H, the vertical movement amount V, and the rotation amount α to zero. In step S56, the CPU 21 displays a warning display indicating that the lateral shift movement is impossible, the vertical shift movement is impossible, and the rotational movement impossibility, that is, the display of the first information IN1 in the inclined state of the first frame F1, or the second frame F2. If the display of the first information IN1 in a state where the right side portion or the like is emphasized is cancelled. In step S57, the CPU 21 determines that the position S (Sx, Syl, Syr) to which the movable part 30a should move is the movement center position of the movable part 30a and the four sides constituting the outer shape of the imaging surface of the imaging element 39a1 are the first. It is set so as to be parallel to the direction x or the second direction y (see (6) in FIG. 16).

  In step S58, the CPU 21 determines whether or not the release switch 13a is turned on. If the release switch 13a is not turned on, the process proceeds to step S59. If the release switch 13a is on, the process proceeds to step S61.

  In step S <b> 59, the CPU 21 determines values of the horizontal movement amount H, the vertical movement amount V, and the rotation amount α in accordance with the operation state of the composition adjustment key 16. In step S60, the CPU 21 determines the movement position Sx of the horizontal driving point DPx, the movement position Syl of the first vertical driving point DPyl, and the second vertical movement based on the horizontal movement amount H, the vertical movement amount V, the rotation amount α, and the like. The movement position Syr of the direction driving point DPyr is calculated (see (2) in FIG. 16). Details of the calculation of the position S (the horizontal component Sx, the first vertical component Syl, and the second vertical component Syr) to which the movable unit 30a should move will be described later using the flowchart of FIG.

  In step S61, based on the position S (Sx, Syl, Syr) and the current position P (pdx, pdyl, pdyr) set in any of steps S57 and S60, the CPU 21 drives necessary for the movement of the movable portion 30a. Force D, that is, a lateral driving force Dx (lateral PWM duty dx) necessary for driving the lateral coil 31a and a first longitudinal driving force Dyl (necessary for driving the first longitudinal coil 32a1). The first vertical PWM duty dyl) and the second vertical driving force Dyr (second vertical PWM duty dyr) necessary to drive the second vertical coil 32a2 are calculated (see (5) in FIG. 16). ).

  In step S62, the horizontal coil 31a is driven via the driving driver circuit 29 with the horizontal PWM duty dx, and the first vertical coil 32a1 is driven via the driving driver circuit 29 with the first vertical PWM duty dyl. The second vertical coil 32a2 is driven through the driver circuit 29 by the two vertical PWM duties dyr, and the movable part 30a is moved (see (3) in FIG. 16). The operations in steps S61 and S62 are automatic control calculations used in PID automatic control for performing general proportional, integral, and differential calculations.

  In step S63, the CPU 21 calculates the movable portion inclination angle LVL (LVL = Kθ + α, see (7) in FIG. 16). In step S64, when the first information IN1 is not displayed on the through image, the CPU 21 displays the first information IN1 on the through image. When the first information IN1 has already been displayed, this display state is maintained. When the second information IN2 is not displayed on the through image, the CPU 21 displays the second information IN2 on the through image based on the camera tilt angle Kθ obtained in step S53. When the second information IN2 is already displayed, the display state of the second information IN2 on the through image is updated based on the camera tilt angle Kθ obtained in step S53.

  Next, the calculation processing of the camera tilt angle Kθ performed in step S53 of FIG. 26 will be described using the flowchart of FIG. When the calculation process is started, in step S71, the CPU 21 determines whether or not the absolute value of the second digital acceleration Aav is greater than or equal to the absolute value of the first digital acceleration Aah. If not, the process proceeds to step S72. If larger, the process proceeds to step S75.

  In step S72, the CPU 21 determines whether or not the first digital acceleration Aah is 0 or more. If it is not greater than 0, assuming that the imaging device 1 is held in a state close to the first vertical position and posture state, the CPU 21 arcsine-converts the camera tilt angle Kθ with respect to the second digital acceleration Aav in step S73. Set the value to the one with a minus sign. If it is greater than or equal to 0, assuming that the imaging device 1 is held in a state close to the second vertical position and posture state, in step S74, the CPU 21 converts the camera tilt angle Kθ into an arc sine with respect to the second digital acceleration Aav. Set the value to

  In step S75, the CPU 21 determines whether or not the second digital acceleration Aav is 0 or more. If it is not equal to or greater than 0, it is assumed that the imaging apparatus 1 is held in a state close to the inverted lateral position and posture. Set to. If it is greater than or equal to 0, assuming that the imaging apparatus 1 is held in a state close to the upright lateral position and posture state, in step S77, the CPU 21 converts the camera tilt angle Kθ into an arc sine with respect to the first digital acceleration Aah. And set the value with a minus sign.

  Next, the second interrupt process started in step S13 in FIG. 25 and performed at regular time intervals (1 ms) will be described with reference to the flowchart in FIG. When the second interrupt process is started, in step S81, the CPU 21 determines whether or not the right direction key 16a is pressed and a right direction switch (not shown) is turned on. If the right switch is turned on, in step S82, the CPU 21 increases the lateral movement amount H by a certain amount (here, 1). Thereafter, the process proceeds to step S83. If the right switch is not turned on, the process proceeds to step S83 without going through step S82. In step S83, the CPU 21 determines whether or not the left direction key 16b is pressed and a left direction switch (not shown) is turned on. If the right switch is turned on, in step S84, the CPU 21 decreases the lateral movement amount H by a certain amount (here, 1). Thereafter, the process proceeds to step S85. If the left switch is not turned on, the process proceeds to step S85 without going through step S84.

  In step S85, the CPU 21 determines whether or not the upward key 16c is pressed and an upward switch (not shown) is turned on. When the upward switch is turned on, in step S86, the CPU 21 increases the vertical movement amount V by a certain amount (here, 1). Thereafter, the process proceeds to step S87. If the upward switch is not turned on, the process proceeds to step S87 without going through step S86. In step S87, the CPU 21 determines whether or not the downward key 16d is pressed and a downward switch (not shown) is turned on. When the downward switch is turned on, in step S88, the CPU 21 decreases the vertical movement amount V by a certain amount (here, 1). Thereafter, the process proceeds to step S89. If the down switch is not turned on, the process proceeds to step S89 without going through step S88.

  In step S89, the CPU 21 determines whether or not the left rotation key 16f is pressed and a left rotation switch (not shown) is turned on. When the left rotation switch is turned on, in step S90, the CPU 21 decreases the rotation amount α by a certain amount (here, 1). Thereafter, the process proceeds to step S91. If the left rotation switch is not turned on, the process proceeds to step S91 without going through step S90. In step S91, the CPU 21 determines whether or not the right rotation key 16e is pressed and a right rotation switch (not shown) is turned on. When the right rotation switch is turned on, in step S92, the CPU 21 increases the rotation amount α by a fixed amount (here, 1) and then ends. If the right rotation switch is not turned on, the process ends without going through step S92.

  Next, regarding the calculation processing of the position S (lateral component Sx, first longitudinal component Syl, second longitudinal component Syr) to be moved performed in step S60 of FIG. 26, the flowchart of FIG. It explains using. When the calculation of the position S is started, in step S101, the CPU 21 calculates the first movement amount Rx and the second movement amount Ry based on the rotation amount α. In step S102, the CPU 21 determines whether or not the absolute value of the first movement amount Rx is greater than the first lateral movement amount Tsx, or whether the absolute value of the second movement amount Ry is the first vertical movement amount Tsy. It is judged whether it is larger than. If it is not large, a horizontal shift movement corresponding to the horizontal movement amount H and a vertical shift movement corresponding to the vertical movement amount V may be performed, and then the movable unit 30a may be rotated by the rotation amount α. Then, it is determined that the movable part 30a does not hit the frame indicating the outer shape of the movable range of the movable part 30a, the process proceeds to step S103, and if it is larger, the horizontal shift movement is performed corresponding to the horizontal movement amount H, and When the movable portion 30a is rotated by the rotation amount α after performing the vertical shift movement corresponding to the vertical movement amount V, a part of the movable portion 30a shows the outline of the movable range of the movable portion 30a. The process proceeds to step S106.

  In step S103, the CPU 21 calculates a first horizontal shift amount SHX1, a first vertical shift amount SHY1, and a third vertical shift amount SHY3 based on the rotation amount α. In step S104, the CPU 21 calculates the second lateral movement amount Ksx based on the first lateral movement amount Tsx, the first movement amount Rx, and the lateral movement amount H, and calculates the first vertical movement amount Tsy, the first movement amount Tsy, and the first movement amount Tsy. Based on the two movement amounts Ry and the vertical movement amount V, the second vertical movement amount Ksy is calculated. In step S105, the CPU 21 cancels the warning display (display of the first information IN1 in a state where the first frame F1 is tilted) indicating that the rotational movement is impossible, if it is performed.

  In step S106, the CPU 21 determines whether or not the rotation amount α is less than zero. When the rotation amount α is equal to or greater than 0, the CPU 21 determines that the clockwise rotation of the composition cannot be performed, and in step S107, the first information IN1 is displayed and the first frame F1 is tilted to the lower right. Then, a part of the vertex of the rectangle constituting the outer shape of the first frame F1 is brought into contact with the second frame F2, and the contacted side of the second frame F2 is emphasized. When the rotation amount α is less than 0, the CPU 21 determines that the counterclockwise rotational movement of the composition cannot be performed, and in step S108, the display of the first information IN1 is tilted with the first frame F1 to the lower left, A part of a rectangular vertex constituting the outer shape of one frame F1 is brought into contact with the second frame F2, and the contacted side of the second frame F2 is emphasized (see FIG. 10).

  In step S109, the CPU 21 determines whether or not the absolute value of the lateral movement amount H is larger than the second lateral movement amount Ksx. If not, even if the movable portion 30a is laterally shifted by the lateral movement amount H, it is determined that the movable portion 30a does not hit the frame indicating the outer shape of the movable range of the movable portion 30a, and the process proceeds to step S110. If it is larger, it is determined that a part of the movable part 30a hits a frame indicating the outer shape of the movable range of the movable part 30a when the movable part 30a is laterally shifted by the lateral movement amount H, and the process proceeds to step S113. It is advanced.

  In step S110, the CPU 21 sets the second lateral shift amount SHX2 to the lateral movement amount H. In step S111, the CPU 21 calculates the first lateral movement amount Tsx based on the second lateral movement amount Ksx, the lateral movement amount H, and the first movement amount Rx. In step S112, the CPU 21 cancels the warning display (display of the first information IN1 in a state in which the right side portion of the second frame F2, etc. is emphasized) indicating that the lateral shift movement is impossible. .

  In step S113, the CPU 21 determines whether or not the lateral movement amount H is less than zero. If the lateral movement amount H is less than 0, the CPU 21 determines that the lateral shift movement in the left direction of the composition (the movement of the movable portion 30a in the right direction) cannot be performed, and in step S114, the first information IN1. Is displayed in a state in which the left side portion of the second frame F2 is emphasized (see FIG. 11). If the lateral movement amount H is greater than or equal to 0, the CPU 21 determines that the lateral shift movement of the composition in the right direction (movement of the movable portion 30a in the left direction) cannot be performed, and the first information IN1 in step S115. Is displayed in a state in which the right side portion of the second frame F2 is emphasized.

  In step S116, the CPU 21 determines whether or not the absolute value of the vertical movement amount V is larger than the second vertical movement amount Ksy. If not, even if the movable portion 30a is vertically shifted by the vertical movement amount V, it is determined that the movable portion 30a does not hit the frame indicating the outer shape of the movable range of the movable portion 30a, and the process proceeds to step S117. If it is larger, it is determined that when the movable portion 30a is vertically shifted by the vertical movement amount V, it is determined that a part of the movable portion 30a hits a frame indicating the outer shape of the movable range of the movable portion 30a. It is advanced.

  In step S117, the CPU 21 sets the second vertical shift amount SHY2 and the fourth vertical shift amount SHY4 to the vertical movement amount V. In step S118, the CPU 21 calculates the first vertical movement amount Tsy based on the second vertical movement amount Ksy, the vertical movement amount V, and the second movement amount Ry. In step S119, the CPU 21 cancels the warning display (display of the first information IN1 in a state where the upper side of the second frame F2, etc. is emphasized) indicating that the vertical shift cannot be performed. .

  In step S120, the CPU 21 determines whether the vertical movement amount V is less than zero. When the vertical movement amount V is less than 0, the CPU 21 determines that the vertical shift movement in the downward direction of the composition (the upward movement of the movable portion 30a) cannot be performed, and the first information IN1 is determined in step S121. Is displayed in a state where the lower side of the second frame F2 is emphasized (see FIG. 12). When the vertical movement amount V is equal to or greater than 0, the CPU 21 determines that vertical shift movement in the upward direction of the composition (downward movement of the movable portion 30a) is not possible, and the first information IN1 in step S122. Is displayed in a state in which the upper side of the second frame F2 is emphasized.

  In step S123, the CPU 21 calculates a lateral component (movement position of the lateral driving point DPx) Sx of the position S based on the first lateral shift amount SHX1 and the second lateral shift amount SHX2, and the first longitudinal shift amount SHX2 is calculated. Based on the direction shift amount SHY1 and the second vertical shift amount SHY2, a first vertical component (movement position of the first vertical drive point DPyl) Syl of the position S is calculated, and the third vertical shift amount SHY3, Based on the four vertical shift amounts SHY4, a second vertical component (movement position of the second vertical drive point DPyr) Syr of the position S is calculated.

  Note that the second information IN2 may be a form in which only the movable portion inclination angle LVL is displayed as a bar as information relating to the sum of the inclination angle and the rotation amount (see FIG. 30).

  Moreover, although the imaging device 1 demonstrated the position detection by the Hall element part 44a using a Hall element as a magnetic field change detection element, you may utilize another detection element as a magnetic field change detection element. Specifically, an MI sensor (high frequency carrier type magnetic field sensor) capable of obtaining the position detection information of the movable part by detecting a change in the magnetic field, a magnetic resonance type magnetic field detection element, an MR element (magnetoresistance effect element) The same effect as that of the present embodiment using the Hall element can be obtained.

  The movable unit 30a may be used as an image blur correction device. When performing the image blur correction process, the CPU 21 does not take into account the lateral movement amount H, the vertical movement amount V, and the rotation amount α set by using the composition adjustment key 16, and an angular velocity sensor (not shown) or the like. The movement control of the movable part 30a is performed based on the blur amount detected from the above.
