Description

  The present invention relates to an imaging device capable of capturing a moving image and a still image. In particular, the present invention relates to an imaging device with improved operability for capturing moving images.

  2. Description of the Related Art In recent years, digital still cameras (hereinafter, referred to as DSCs) that can immediately confirm a captured image have been rapidly spread. As a lens barrel for the DSC, a so-called collapsible lens barrel in which the length of the lens barrel is shortened during non-photographing is generally adopted in consideration of portability during non-photographing. . In addition, for higher functionality, not only still image shooting but also moving image shooting including sound can be performed using the same optical system (for example, see Patent Document 1).

FIG. 30 shows an exploded perspective view of a conventional collapsible lens barrel (for example, see Patent Document 2). The collapsible lens barrel 70 is an optical system that changes the focal length by moving the movable lens frames 72 and 73 in the front-rear direction by one cam barrel 71. Cam grooves 74 and 75 are formed on the inner peripheral surface of the cam cylinder 71, and the cam grooves 74 and 75 determine the movement trajectories of the movable lens frames 72 and 73, respectively. The movable lens frames 72 and 73 move in the optical axis (Z-axis) direction when three cam pins 72a and 73a provided on the respective outer peripheral surfaces engage with the cam grooves 74 and 75, respectively. The cam cylinder 71 is provided outside the fixed cylinder 80, and is rotatable around the optical axis. A gear 76 is formed on the outer periphery of the cam cylinder 71, and a driving force transmission gear 77 meshes with the gear 76. The driving force transmission gear 77 is connected to an output shaft of a cam cylinder driving actuator 79 via a reduction gear train 78. Therefore, when the cam cylinder driving actuator 79 is driven, the driving force is transmitted to the driving force transmission gear 77 via the reduction gear train 78, and the cam cylinder 71 is rotated. As a result, the movable lens frames 72 and 73 move along the shapes of the cam grooves 74 and 75, respectively, so that zooming is performed from the collapsed state via the wide-angle end.

  The retractable lens barrel 1 will be described with reference to FIGS. As shown in the drawing, an XYZ three-dimensional orthogonal coordinate system is set in which the optical axis of the retractable lens barrel is the Z axis (the object side is positive). L1 is a first-group lens, L2 is a second-group lens that moves on the optical axis (Z-axis) to perform zooming, L3 is a third-group lens for image blur correction, and L4 is a lens for correcting image plane fluctuation due to zooming. The fourth lens group moves on the optical axis for focusing.

  The first-group holding frame 2 holds the first-group lens L1, and is fixed to the cylindrical first-group moving frame 3 with screws or the like so that the central axis of the first-group lens L1 is parallel to the optical axis. I have. One end of two guide poles (guide members) 4a, 4b parallel to the optical axis is fixed to the first group moving frame 3.

  The second group moving frame 5 holds the second group lens L2 and is slidable in the optical axis direction by being supported by the two guide poles 4a and 4b described above. The second group moving frame 5 is engaged with a feed screw 6a of a second group lens driving actuator 6 such as a stepping motor and a screw portion of a rack 7 provided on the second group moving frame 5 so that the second group lens driving actuator 6 With the driving force described above, the lens is moved in the optical axis direction to perform zooming.

  The third group frame 8 holds an image blur correction lens group L3 (third group lens), and forms an image blur correction device 31.

  The fourth group moving frame 9 is slid in the optical axis direction by being supported by two guide poles 11a and 11b parallel to the optical axis and sandwiched between the third group frame 8 and the master flange 10. It is possible. Further, the fourth group moving frame 9 is engaged with a feed screw 12a of a fourth group lens driving actuator 12 such as a stepping motor and a screw portion of a rack 13 provided on the fourth group moving frame 9 so as to be engaged. Is moved in the direction of the optical axis by the driving force, and correction and focusing of the image plane fluctuation due to zooming are performed.

  The image pickup device (CCD) 14 is attached to the master flange 10.

  Next, a method of supporting the guide poles 4a and 4b will be described with reference to FIG.

  The third group frame 8 is provided with support portions 8a (main shaft side) and 8b (rotation stop side). When the guide poles 4a and 4b penetrate the support portions 8a and 8b, the guide poles 4a and 4b are held parallel to the optical axis. Since the guide poles 4a and 4b slide in the optical axis direction with respect to the two support portions 8a and 8b, the first group lens L1 held by the first group moving frame 3 fixed to one end of the guide poles 4a and 4b. Is maintained with respect to the image blur correction lens L3 provided in the third group frame 8. Further, the guide poles 4a and 4b slidably penetrate the support portions 5a (rotation-stop side) and 5b (main shaft side) provided on the second group moving frame 5, so that the second group moving frame 5 Since the second group lens L2 held by the second group moving frame 5 is supported by the second group moving frame 5 with respect to the image blur correcting lens L3 provided in the third group frame 8, the lens is supported by the slidable optical axis directions 4a and 4b. Is kept.

  Here, the relationship between the first group lens L1, the second group lens L2, and the third group lens L3 described above will be described with reference to FIGS. 3 (a) to 3 (c). In the figure, arrows L1a and L2a indicate the directions of the central axes of the first group lens L1 and the second group lens L2, respectively.

  FIG. 3A shows an ideal state of the three lens units L1, L2, and L3, with respect to the Z axis (the optical axis of the lens barrel, which coincides with the central axis of the third lens unit L3). The center axis L1a of the first lens unit L1 and the center axis L2a of the second lens unit L2 are parallel to each other.

  FIG. 3B shows a cam lens 72a and a moving lens frame 73 provided on the moving lens frame 72 shown in FIG. 30 by connecting the first lens group L1 and the second lens group L2 in the same manner as the conventional lens barrel shown in FIG. The case where each is supported by the cam pin 73a provided in each of FIGS. In this case, due to variations in the accuracy of the cam pins 72a and 73a and the cam grooves 74 and 75, the central axis L1a of the first lens group L1 and the central axis L2a of the second lens group L2 are not parallel to each other and are also parallel to the Z axis. Not be. Therefore, there is a great possibility that the optical performance is deteriorated.

  FIG. 3C shows the case of the present embodiment. Since the first group lens L1 and the second group lens L2 are supported by the same guide poles 4a and 4b, the center axis L1a of the first group lens L1 and the center axis L2a of the second group lens L2 are temporarily inclined with respect to the Z axis. Even if it does, the directions of both central axes L1a and L2a always coincide. That is, the first lens unit L1 and the second lens unit L2 are always tilted in the same direction with respect to the image blur correction lens unit L3 having the highest influence on the optical performance, so that the deterioration amount of the optical performance can be minimized. .

  Next, a configuration for moving the first lens unit L1 in the optical axis direction will be described.

  A gear 15a is formed on a part of the inner peripheral surface of the substantially hollow cylindrical drive frame 15 on the image sensor 14 side. Also, three projections 15b are formed on the inner peripheral surface on the object side (positive side of the Z axis) at intervals of approximately 120 °. When the protrusion 15b engages with three circumferential grooves 3a provided on the outer peripheral surface of the first group moving frame 3 on the image sensor 14 side, the drive frame 15 moves the optical axis with respect to the first group moving frame 3. The drive frame 15 and the first-group moving frame 3 move integrally in the optical axis direction. Further, three cam pins 16a, 16b, 16c are press-fitted and fixed at 120 ° intervals on the inner peripheral surface of the drive frame 15.

  On the outer surface of the cylindrical cam frame 17, three cam grooves 18a, 18b and 18c are formed at intervals of about 120 °. FIG. 4 is a development view of the outer peripheral surface of the cam frame 17. The cam pins 16a, 16b, 16c of the drive frame 15 engage with the cam grooves 18a, 18b, 18c of the cam frame 17, respectively. Each of the cam grooves 18a, 18b, 18c has a portion 19a substantially parallel to the circumferential direction of the cam frame 17 on the image sensor 14 side (negative side of the Z axis) and a cam frame on the object side (positive side of the Z axis). 17 has a portion 19c that is substantially parallel to the circumferential direction, and a portion 19b that spirally connects the portion 19a and the portion 19c. When the cam pins 16a, 16b, and 16c are in the portion 19a, the first lens unit L1 stops in a state of being retracted toward the image sensor 14 (retracted state). From this state, when the drive frame 15 rotates around the optical axis, the cam pins 16a, 16b, and 16c reach the portion 19c via the portion 19b. When the cam pins 16a, 16b, 16c are in the portion 19c, the first lens unit L1 is extended toward the object side and stopped.

  Between the cam groove 18b and the cam groove 18c on the outer peripheral surface of the cam frame 17, a bearing portion 17d rotatably holding the drive gear shafts 20 at both ends of the spline-shaped drive gear 19, and a drive gear 19 A drive gear mounting portion (recess) 17a recessed into a semi-cylindrical surface is formed to avoid interference with the drive gear 19, whereby the drive gear 19 is rotatably held on the outer peripheral surface of the cam frame 17. I have. The drive gear 19 transmits a driving force of a drive unit 21 attached to the master flange 10 described later to a gear portion 15 a provided on the drive frame 15. Therefore, the rotation of the drive gear 19 causes the drive frame 15 to rotate around the optical axis. At this time, the cam pins 16a, 16b, 16c provided on the drive frame 15 are moved by the cam grooves 18a, 18b of the cam frame 17. , 18c, the drive frame 15 also moves in the optical axis direction. At this time, the rotation of the first group moving frame 3 around the optical axis is restricted by the two guide poles 4a, 4b fixed to the first group moving frame 3 penetrating the support portions 8a, 8b of the third group frame 8. Therefore, as the drive frame 15 moves in the optical axis direction, the first group moving frame 3 moves straight in the optical axis direction.

  The drive actuator 6 of the second group moving frame 5 is fixed to the mounting portion 17b of the cam frame 17. The drive actuator 12 of the fourth group moving frame 9 is fixed to the mounting portion 10a of the master flange 10. The drive unit 21 for transmitting the driving force to the drive gear 19 includes a drive actuator 22 and a reduction gear unit 23 composed of a plurality of gears, and is fixed to the mounting portion 10b of the master flange 10.

  The shutter unit 24 includes an aperture blade and a shutter blade having a constant aperture diameter for controlling the exposure amount and the exposure time of the image sensor 14.

  The origin detection sensor 25 for the second group moving frame 5 is a light detection sensor including a light emitting element and a light receiving element, and is a position in the optical axis direction of the second group moving frame 5, that is, an origin position (absolute position) of the second group lens L2. Is detected. As shown in FIG. 5, the origin detection sensor 25 is attached to the attachment portion 17c of the cam frame 17, and the second group moving frame 5 has moved to the position closest to the image sensor 14 (−Z direction side) or its vicinity. At this time, the blade 5c provided on the second group moving frame 5 passes through the front of the origin detection sensor 25 and blocks the light to detect the origin position. When the origin is detected, the second-group moving frame 5 and the rack 7 attached to the second-group moving frame are located closest to the drive motor 6 and closer to the image sensor 14. This state corresponds to the state of FIG. 10 described later.

  The origin detection sensor 26 for the fourth group moving frame 9 detects the position of the fourth group moving frame 9 in the optical axis direction, that is, the origin position of the fourth group lens L4. The origin detection sensor 27 for the drive frame 15 detects the position of the drive frame 15 in the rotation direction, that is, the origin position of the first-group moving frame 3 and the first-group lens L1 that move together with the drive frame 15.

  The image blur correction device 31 adjusts the image blur correction lens group L3 for correcting image blur at the time of shooting by pitching in the first direction (Y direction) and yawing in the second direction (X direction). Move in the direction and. The first electromagnetic actuator 41y generates a driving force in the Y direction, and the second electromagnetic actuator 41x generates a driving force in the X direction. , Y.

  Next, an actuator drive circuit of an image pickup apparatus (here, DSC 35) equipped with the retractable lens barrel will be described with reference to FIG.

  The DSC 35 is equipped with a microcomputer 36 for controlling the DSC 35. The microcomputer 36 controls the driving of the first lens drive actuator 22 via the drive control means 40 based on a signal from a power button 37 provided on the DSC 35, and the origin detection sensor 27 detects the origin position of the first lens L1. Is detected, the first lens unit L1 is driven to a predetermined position. Further, the microcomputer 36 controls the driving of the second lens drive actuator 6 via the drive control means 41 based on the signal from the zoom lever 38, and the origin detection sensor 25 detects the origin position of the second lens L2. Thereafter, the second group lens L2 is driven to a predetermined zoom position. Further, when the shutter button 39 is pressed, the microcomputer 36 controls the drive of the fourth lens drive actuator 12 via the drive control means 42. After the origin detection sensor 26 detects the origin position of the fourth lens L4, the microcomputer 36 adjusts the focus. Perform alignment.

  The photographing mode selection dial 53 is a rotary dial provided on the DSC 35 as shown in FIG. Each mode can be selected by rotating the shooting mode selection dial 53 so that the pictograph indicating each mode matches the reference position 53a. The shooting mode selection dial 53 includes a program mode “P” 53b, an aperture priority mode “A” 53c, and a shutter priority mode “S” 53d as still image shooting modes. A mode 53f and a photographed image transmission mode 53g are provided.

  Next, an image processing circuit of the DSC 35 will be described with reference to FIG.

  The image pickup device (CCD) 14 converts an image incident through the collapsible lens barrel 1 into an electric signal, and its operation is controlled by the image pickup device drive control means 43. The analog signal processing means 44 performs analog signal processing such as gamma processing on the video signal obtained by the image sensor 14. The A / D converter 45 converts the analog video signal output from the analog signal processor 44 into a digital signal. The digital signal processing means 46 performs digital signal processing such as noise removal and contour enhancement on the video signal converted into a digital signal by the A / D conversion means 45. The frame memory 47 temporarily stores the image signal that has passed through the digital signal processing means 46. The image recording control unit 48 controls writing of the image once stored in the frame memory 47 to the image recording unit 49 such as an internal memory or a recording medium. The captured image recorded in the image recording means 49 is displayed on an image display device 52 such as a liquid crystal monitor mounted on the DSC 35 via a frame memory 51 by a signal from the image display control means 50.

  The operation of the thus configured DSC 35 will be described below.

  First, the retractable lens barrel 1 shifts from the non-imaging (unused) state illustrated in FIG. 10 to the imaging state illustrated in FIGS. 11 and 12, and the DSC 35 can perform imaging. The operation up to this point will be described with reference to the flowchart shown in FIG.

  First, when shooting a moving image, the moving image shooting mode 53e is selected by the shooting mode selection dial 53 (S101). At this time, the lens barrel 1 is in a non-photographing state shown in FIG. The power of the DSC 35 is turned on by pressing the power button 37 (S102). When the power is turned on, first, the first-group lens drive actuator 22 that drives the first-group lens L1 rotates, and rotates the drive gear 19 via the reduction gear unit 23. When the drive gear 19 rotates, the drive frame 15 meshed with the drive gear 19 rotates about the optical axis along the cam grooves 18a, 18b, 18c. After the origin detection sensor 27 is initialized, the drive frame 15 moves in the object direction (Z-axis direction), so that the first-group moving frame 3 also moves in the object direction. When a rotation amount detection sensor (not shown) detects that the first group lens driving actuator 22 has rotated by a predetermined rotation amount, the first group moving frame 3 moves to a predetermined position, and then the first group lens driving actuator 22 The rotation stops. At this stop position, the cam pins 16a, 16b, 16c have reached a portion 19c substantially parallel to the circumferential direction of the cam frame 17 in the developed view of the cam groove in FIG. FIG. 11 shows the state at this time.

  Next, in order to move the second group lens L2, which is a zooming lens, to a predetermined position, the second group lens drive actuator 6 is rotated, and the rack 7 is driven via the feed screw 6a. Start moving along the Z axis.

  Here, when the microcomputer 36 of the DSC 35 has set the initial position of the zoom magnification after power-on near the wide-angle end, the second group moving frame 5 initializes the origin detection sensor 25, and The camera stops near the wide-angle end shown in FIG. 12, and the DSC 35 enters a shooting preparation state.

  Next, the microcomputer 36 determines whether or not the shooting mode selection dial 53 is in the moving image shooting mode 53e (S103). When the moving image shooting mode 53e is selected, the moving image shooting is automatically started (S105). On the other hand, when the still image shooting modes 53b to 53d are selected, the camera enters a shooting standby state and waits for the next instruction from the photographer. To end the moving image shooting, the shutter button 39 is fully pressed (S106). As a result, the moving image shooting ends and the camera enters a shooting standby state. In the photographing standby state, the photographer can press a shutter button 39 to take a still image or a moving image again according to the state of the photographing mode selection dial 53.

  As for the zooming operation at the time of shooting, it is possible to shoot at an arbitrary zoom position by moving the second lens group L2, which is a zooming lens, from the wide-angle end position shown in FIG. 12 to the telephoto end position shown in FIG. It is.

  Here, in any of the above cases, the first group moving frame 3 and the second group moving frame 5 are supported by the same guide poles 4a, 4b held by the support portions 8a, 8b of the third group frame 8. Move to a predetermined position. Therefore, even if the first lens unit L1 and the second lens unit L2 are inclined with respect to the optical axis, their inclination directions are the same as those of the image blur correction lens unit L3, so that a predetermined optical performance is ensured. Can be.

  Next, an operation when shifting from the state at the time of each photographing shown in FIGS. 11 and 12 to the state at the time of non-photographing shown in FIG. 10 will be described.

  When the power button 37 of the DSC 35 is turned off from the state at the time of each photographing, the photographing is terminated, and the second group moving frame 5 is first moved to the image sensor 14 by the second group lens driving actuator 6, and FIG. The state shown in FIG. Next, the first lens drive actuator 22 rotates, and the drive gear 19 is rotated via the reduction gear unit 23 in the opposite direction. When the drive gear 19 rotates, the drive frame 15 meshed with the drive gear 19 rotates about the optical axis, and at the same time, moves toward the image sensor 14 by the cam grooves 18a, 18b, and 18c, whereby 1 The group moving frame 3 also moves. When the rotation of the drive frame 15 is detected by the origin detection sensor 27, the rotation of the first-group lens drive actuator 22 is stopped after the first-group moving frame 3 moves to a predetermined position. At this stop position, the cam pins 16a, 16b, 16c have reached a portion 19a substantially parallel to the circumferential direction of the cam frame 17 in the developed view of the cam groove in FIG. As a result, the state shifts to the state shown in FIG. 10, and the collapsed state is shorter than the state at the time of shooting by the length c.

  Here, the collapsing operation for changing the length of the collapsible lens barrel 1 in the optical axis direction uses the first lens drive actuator 22 for driving the first lens L1, and the zooming operation uses the second lens drive actuator 6 alone. Used in. Therefore, since the zooming operation in actual photographing is performed with the first group lens L1 extended, it is not necessary to operate the first group lens drive actuator 22, and only the second group lens drive actuator 6 is driven to obtain the zooming operation from FIG. Zooming can be performed by moving the second lens unit L2 to an arbitrary position in FIG. Therefore, when performing photographing such as performing a zooming operation, unlike the collapsible lens barrel of the conventional system shown in FIG. 30, it is necessary to perform the extending operation and the retracting operation of the lens barrel according to the zoom magnification. Absent. In the conventional collapsible lens barrel shown in FIG. 30, during the zooming operation, one drive actuator 79 is rotated, and the cam barrel 71 is rotated via the reduction gear train 78 so that the movable lens frames 72 and 73 are simultaneously moved. Since it was driven, the zooming speed is slow and the driving noise is loud. The collapsible lens barrel 1 of the present invention uses a stepping motor as the second group lens driving actuator 6 and directly drives the second group moving frame 5 via a feed screw 6a attached to the stepping motor. Feeding speed is fast and operation noise is low. Therefore, the photographer can instantly change the angle of view, and can perform a usage method that is not suitable for the conventional DSC, such as following a subject or shooting a moving image with sound.

  As described above, according to the first embodiment, in a DSC that can capture both a moving image and a still image, when the power of the DSC is turned on in a state where the moving image capturing mode is selected, the DSC is automatically turned on. Movie shooting starts. Therefore, it is possible to achieve a DSC optimal for moving image shooting, in which moving image shooting can be started immediately after chasing a subject.

  Further, in a DSC equipped with a lens capable of high magnification, the first group lens L1 and the second group lens L2 are configured to be inclined at least in the same direction with respect to the image blur correction lens L3, so that the optical performance is reduced. And the total length when not in use can be shortened while minimizing the effect.

  Note that the third group lens L3 can be moved in the direction orthogonal to the optical axis by using the image blur correction device 31, but the third group lens L3 is fixed to the third group frame 8, and the image blur correction device is mounted. It goes without saying that the same effect can be obtained even if a general lens barrel is used.

  Note that, in the first embodiment, when the moving image shooting mode is selected, the moving image shooting is automatically started when the power is turned on. It is also possible to configure so that moving image shooting is not started until the button is pressed. In this case, it is possible to avoid a malfunction such that the power is carelessly turned on and the moving image shooting is started.

(Embodiment 2)
Next, an imaging device according to Embodiment 2 of the present invention will be described with reference to FIG. FIG. 14 is a flowchart illustrating a shooting operation of the imaging device according to the second embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

  The operation will be described below with reference to the flowchart shown in FIG. First, the power of the main body of the DSC 35 is turned on (S201), whereby the DSC 35 enters a shooting standby state (S202). Next, when performing moving image shooting, the moving image shooting mode 53e is selected with the shooting mode selection dial 53 (S203). When the moving image shooting mode 53e is selected, the moving image shooting is automatically started (S204). In this case, it is not necessary to press the shutter button 39 or the like, and the moving image shooting starts immediately. To end the moving image shooting, the shutter button 39 is fully pressed (S205), and the shooting ends.

  As described above, according to the second embodiment, in the DSC capable of shooting both a moving image and a still image, when the moving image shooting mode is selected while the power is on, the moving image shooting starts automatically. I do. Therefore, it is not necessary to separately press a shutter button or the like to start moving image shooting, and moving image shooting can be started instantaneously. As a result, it is possible to reduce the chances of missing important photo opportunities.

  In the second embodiment, when the moving image shooting mode is selected, the moving image shooting is automatically started. However, until the photographer presses the shutter button by the menu selection operation, the moving image shooting mode is started. It is also possible to configure so that movie shooting is not started. In this case, it is possible to avoid an erroneous operation in which the shooting mode selection dial is inadvertently turned to start moving image shooting.

(Embodiment 3)
Next, an imaging device according to Embodiment 3 of the present invention will be described with reference to FIG. FIG. 15 is a flowchart illustrating a shooting operation of the imaging device according to the third embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

  The operation will be described below with reference to the flowchart shown in FIG. First, when shooting a moving image, the moving image shooting mode 53e is selected by the shooting mode selection dial 53 (S301). At this time, the lens barrel 1 is in a non-photographing state shown in FIG. The power of the DSC 35 is turned on by pressing the power button 37 (S302). When the power is turned on, the first-group lens actuator 22, the second-group lens actuator 6 rotates, and the first-group lens L1 and the second-group lens L2 move by a predetermined amount in the optical axis Z direction. It stops near, and the DSC 35 enters a shooting preparation state.

  Next, the microcomputer 36 determines whether or not the shooting mode selection dial 53 is in the moving image shooting mode 53e (S303). If the moving image shooting mode 53e has been selected, the process proceeds to the next step (S305). If the still image shooting modes 53b to 53d have been selected, a shooting standby state is set (S304). Next, when the moving image shooting mode 53e is selected, when the shutter button 39 is fully pressed (S305), at least one still image is shot before starting moving image shooting (S306). This still image is written to a recording medium such as a memory card via the frame memory 47 via the image recording means 49, and the shooting of the still image ends (S307). When the shooting of the still image is completed, the mode is automatically shifted to the moving image shooting mode, and the moving image shooting is started (S308). To end the moving image shooting, the shutter button 39 is fully pressed (S309). As a result, the moving image shooting ends and the camera enters a shooting standby state.

  As described above, according to the third embodiment, in a DSC capable of capturing both a moving image and a still image, if a moving image is captured in a state in which the moving image capturing mode is selected, immediately before the start of the moving image capturing In addition, since a still image having a higher resolution than that of the moving image is shot, a remarkable effect that a subject at the same time can be shot continuously can be obtained. That is, it is possible to solve the problem that the moving image with sound and the still image cannot be photographed at the same time with the conventional DSC with the retractable lens barrel.

  Note that the number of still images captured before the start of moving image capturing is not limited to one, and a plurality of continuous images may be captured.

(Embodiment 4)
Next, an imaging device according to Embodiment 4 of the present invention will be described with reference to FIGS. 16 is a diagram illustrating a directory structure of a file system of the imaging device according to Embodiment 4, FIG. 17 is a diagram illustrating data of an association information file of the imaging device, and FIG. 18 is a flowchart illustrating a shooting operation of the imaging device. It is. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

  A file management method of a captured image of the DSC 35 will be described with reference to FIGS. A captured image folder 54 (folder name “Picture”) is formed on a recording medium (not shown) in which the captured image is recorded, and an associated information file folder 55 (folder name “Index”) is located below the captured image folder 54 (folder name “Index”). An image folder 56 (folder name “Still”) and a moving image folder 57 (folder name “Movie”) are formed. In the still image folder 56, a still image file 59 in which the photographed still image is stored is created under the name “Still001.jpg”, for example. In the moving image folder 57, a moving image file 60 in which a captured moving image is stored is created under the name of, for example, “Movie001.avi”. Further, in the association information file folder 55, an association information file 58 in which association information for associating a captured moving image and a still image is stored is created with a name, for example, “Index001.html”. That is, as shown in FIG. 17, the file “Index001.html” has a relative path in the directory between “Still001.jpg” of the still image file 59 and “Movie001.avi” of the moving image file 60. By recording (that is, the association information), the association between the still image and the moving image captured at the same time is realized.

  The operation will be described below with reference to the flowchart shown in FIG. First, when a moving image is photographed, the moving image photographing mode 53e is selected by the photographing mode selection dial 53 (S401). At this time, the lens barrel 1 is in a non-photographing state shown in FIG. The power of the DSC 35 main body is turned on by pressing the power button 37 (S402). When the power is turned on, the first-group lens actuator 22, the second-group lens actuator 6 rotates, and the first-group lens L1 and the second-group lens L2 move by a predetermined amount in the optical axis Z direction. It stops near, and the DSC 35 enters a shooting preparation state.

  Next, the microcomputer 36 determines whether or not the shooting mode selection dial 53 is in the moving image shooting mode 53e (S403). If the moving image shooting mode 53e has been selected, the process proceeds to the next step (S405), and if the still image shooting modes 53b to 53d have been selected, a shooting standby state is set (S404). Next, when the moving image shooting mode 53e is selected, when the shutter button 39 is fully pressed (S405), at least one still image is shot before starting the moving image shooting (S406). This still image is written to a recording medium such as a memory card via the image memory 49 via the frame memory 47, and the shooting of the still image ends (S407). In this case, if the still image is to be recorded on a memory card or the like for the first time, a still image folder 56 is created, and then “Still001.jpg” is created as a still image file 59 under the still image folder 56, and the still image is stored therein. . If the still image folder 56 has already been created, only the still image file 59 is created, and the still images are stored in this. Next, when the shooting of the still image is completed, the mode is automatically shifted to the moving image shooting mode, and the shooting of the moving image is started (S408). To end the shooting of the moving image, the shutter button 39 is fully pressed (S409). As a result, the photographing is terminated, and a photographing standby state is set. The captured moving image is written to a memory card or the like via an image recording unit 49 via a frame memory 47. At this time, if the image is to be recorded for the first time on a memory card or the like, a moving image folder 57 is created, and then “Movie001.avi” is created as a moving image file 60 under the moving image folder 57, and the moving image is stored therein. . If the moving image folder 57 has already been created, only the moving image file 60 is created, and the moving image is stored therein. Then, after the still image file 59 and the moving image file 60 are recorded and the association information file folder 55 is created, “Index001.html” is created as the association information file 58 below the hierarchy, and FIG. The association information is recorded.

  As described above, according to the fourth embodiment, in a DSC capable of capturing both a moving image and a still image, a moving image and a still image having a higher resolution than the moving image immediately before the start of the moving image shooting are obtained. And the creation of an association information file, making it possible to easily associate a moving image and a still image created almost at the same time, making file management on a recording medium such as a memory card easy. Is obtained.

  When a still image is shot in the still image shooting mode (the program mode P53b, the aperture priority mode A53c, and the shutter priority mode S53d), a still image file 59 is created and stored in the still image file 59. The still image is saved. At this time, the corresponding association information file 58 is created at the same time, but the moving image file 60 is not created. That is, the moving image file information is blank in the association information shown in FIG.

(Embodiment 5)
Next, an imaging device according to the fifth embodiment of the present invention will be described with reference to FIGS. 19 is a schematic diagram of an image display unit of an imaging device according to Embodiment 5, FIG. 20 is a diagram illustrating a reproduction menu of a moving image in the imaging device, and FIG. 21 is a flowchart illustrating an image reproducing operation in the imaging device. It is. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

  As shown in FIG. 19, a captured still image and a moving image can be displayed on the image display device 52 provided in the DSC 35. The still images and the moving images can be displayed in order by operating the four arrow keys 64 provided in the DSC 35 in the up, down, left, and right directions.

  Hereinafter, a method of reproducing the captured image will be described with reference to the flowchart shown in FIG. First, when reproducing a moving image, the reproduction mode 53f is selected by the shooting mode selection dial 53, and a plurality of association information files 58 are read from a memory card or the like (S501). Based on the association information file 58, for example, a still image saved in the file “Still001.jpg” is displayed on the image display device 52 (S502). Next, a selection is made as to whether to reproduce a moving image captured at the same time as the displayed still image (S503). Here, when there is a moving image associated with the still image displayed on the image display device 52, a moving image reproduction menu 69 is displayed together. The moving image reproduction menu 69 includes an arrow mark 69a indicating a reproduction state of the moving image, and an arrow key mark 69b indicating which arrow key 64 should be operated to reproduce the moving image. To display another still image, the page is turned by operating the arrow key 64, and the still image stored in, for example, “Still002.jpg” is displayed. In the case of reproducing a moving image, the reproduction of the moving image associated with the still image displayed at that time is started by pressing the down arrow key 64 (the direction in which the character “SET” is present) ( S504). For example, when a moving image reproduction instruction is given while a still image stored in the still image file “Still001.jpg” is displayed, the moving image is displayed based on the data stored in the “Index001.html” of the association information file 58. Then, the moving image stored in the moving image file “Movie001.avi” is reproduced (S505).

  Here, when there is no moving image associated with the still image, that is, with the shooting mode selection dial 53, a still image shooting mode (program mode P53b, aperture priority mode A53c, shutter priority mode S53d) is selected for shooting. When displaying the reproduced still image, the moving image reproduction menu 69 is not displayed. The still image file 59 stored in the still image folder 56 shown in FIG. 16 corresponds to “Still004.jpg” and “Still005.jpg” among the still image files 59 stored in the still image folder 56 shown in FIG. I do. That is, there exist association information files 58 named “Index004.html” and “Index005.html” corresponding to these, respectively, but corresponding moving images named “Movie004.avi” and “Movie005.avi” respectively. The image file 60 does not exist.

  When a still image with an associated moving image is displayed, a mark 69c indicating that a moving image is present is displayed at the upper right of the image display device 52.

  As described above, according to the fifth embodiment, in a DSC capable of capturing both a moving image and a still image, when the captured image is reproduced, the association information file for associating the moving image with the still image is read. Accordingly, a moving image captured at the same time as the still image and associated with the still image can be easily reproduced. Further, by adding a mark to a still image, it is possible to instantaneously determine whether or not a moving image associated with the still image is present. Can be

(Embodiment 6)
Next, an imaging device according to Embodiment 6 of the present invention will be described using FIG. FIGS. 22A and 22B are diagrams for explaining thumbnail display of a still image according to the sixth embodiment.

  In the flowchart of FIG. 21 shown in the fifth embodiment, the display of a still image (S502) may be a thumbnail display as shown in FIG.

  When the image display device 52 displays the first to ninth still images as thumbnails, it is usual to arrange and display the still images in order of photographing time as shown in FIG. In this case, as described in the fifth embodiment, a mark 69c indicating that an associated moving image exists is displayed at the upper right of each image. However, if the images are displayed side by side in the order of the photographing time, some of them have associated moving images (Nos. 3 to 7) and some do not have associated moving images (Nos. 1 to 2 and Nos. 8 to 9). Displayed, it is very difficult to see and it is difficult to select a desired image.

  On the other hand, as shown in FIG. 22A, the captured images are rearranged, the still images in which the moving images associated with the first half of the first to fifth are present, and the still images are associated with the second half of the sixth to the ninth. A still image having no moving image is displayed. The rearrangement of the captured images is performed in the image display control unit 50 and the frame memory 51 when the captured images are read from the image recording unit 49.

  As described above, according to the sixth embodiment, when a still image is displayed as a thumbnail, a still image that has conventionally been displayed in the order of shooting time and is difficult to see is associated with a still image having an associated moving image. By classifying and displaying a still image in which no moving image exists, selection and reproduction of a moving image are facilitated.

  In the present embodiment, a still image in which an associated moving image exists and a still image in which an associated moving image does not exist are displayed continuously. It may be inserted. Furthermore, although the case of the thumbnail display has been described, the same effect can be obtained by changing the order in which the still images are displayed, even when the case where the still images are sequentially displayed one by one is applied.

(Embodiment 7)
Next, an imaging device according to a seventh embodiment of the present invention will be described with reference to FIGS. FIG. 23 is a block diagram of a data transmission unit in an imaging device according to the seventh embodiment, FIG. 24 is a diagram illustrating a transmission selection menu of a captured image of the imaging device, and FIG. 25 is a diagram illustrating an image transmission operation of the imaging device. It is a flowchart. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 23 is a block diagram of a data transmission unit provided in the imaging apparatus. The image transmission control unit 61 reads the captured image read from the image recording unit 49 via the frame memory 51 via the captured image transmission unit 62. , From the antenna 63.

  As shown in FIG. 24, the image transmission selection menu 66 displayed on the image display device 52 includes three menus of a still image 66a, a moving image 66b, a still image, and a moving image 66c. Select the image to send.

  Hereinafter, a method for transmitting the captured image will be described with reference to the flowchart shown in FIG. First, when transmitting a photographed image, the transmission mode 53g is selected by the photographing mode selection dial 53, and a plurality of association information files 58 are read from a memory card or the like (S601). Based on the association information file 58, the image display device 52 displays, for example, a still image stored in the “Still001.jpg” file (S602). Next, a selection is made as to whether to transmit the displayed still image or a moving image associated with the still image (S603). Here, when there is a moving image associated with the still image displayed on the image display device 52, as shown in FIG. 24, the still image 66a, the moving image 66b, the still image, and the moving image Three menus indicating transmission of the message 66c are displayed. When reproducing another still image, the page is turned using the arrow keys 64, and the still image saved in, for example, the “Still002.jpg” file is displayed. When transmitting, an image to be transmitted is selected from the image transmission selection menu 66 (S604). When transmitting only the still image, for example, the still image data in the “Still001.jpg” file is transmitted (S605). When transmitting a moving image, based on data in the “Index001.html” file of the association information file 58, for example, moving image data in the “Movie001.avi” file associated with this still image Is transmitted (S606). Further, when both a still image and a moving image are transmitted, for example, the still image data in the “Still001.jpg” file and the “Movie001” are stored based on the data of the “Index001.html” file in the association information file 58. .Avi "is transmitted (S607).

  Here, when there is no moving image associated with the still image, that is, with the shooting mode selection dial 53, a still image shooting mode (program mode P53b, aperture priority mode A53c, shutter priority mode S53d) is selected for shooting. When displaying the displayed still image, the image transmission selection menu 66 does not display the two menus indicating the transmission of the moving image 66b, the still image, and the moving image 66c, but displays only the menu indicating the transmission of the still image 66a.

  When transmitting a captured image, data in the association information file may be transmitted together with the captured image.

  Further, as described in the sixth embodiment, a still image may be displayed as a thumbnail. In this case, the still images may be arranged and displayed in the order of the photographing time. However, the still images having the associated moving image and the still images having no associated moving image are classified and rearranged, so that the desired image can be displayed. Image becomes easier to select.

  As described above, according to the seventh embodiment, in the DSC capable of capturing both a moving image and a still image, when transmitting the captured image, the DSC reads the association information file that associates the moving image with the still image. Accordingly, a moving image captured at the same time as a still image and associated with the still image can be easily selected and transmitted.

  In the present embodiment, the image transmitting unit including the antenna is built in the image pickup apparatus. However, a method in which only a modem or the like is built in and connected to a mobile phone or the like to transmit the image may be used.

  In the present embodiment, a method of selecting a transmission method of a captured image is adopted. However, an initial setting is a method of automatically transmitting only a still image having a small file size, and a moving image is transmitted only when the user needs it. May be changed to be transmittable.

(Embodiment 8)
Next, an imaging device according to an eighth embodiment of the present invention will be described with reference to FIGS. FIG. 26 is a block diagram showing a configuration of an actuator drive circuit of an imaging device according to Embodiment 8, FIG. 27 is a schematic diagram showing an operation panel of a zoom initial position selecting means of the imaging device, and FIG. FIG. 29 is a cross-sectional view of the retractable lens barrel used at an intermediate position between the wide-angle end and the telephoto end, and FIG. 29 is a flowchart illustrating the photographing operation of the imaging apparatus. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

  The block diagram showing the configuration of the actuator drive circuit of FIG. 26 is obtained by adding a zoom initial position storage unit 67 and a zoom initial position selection unit 68 to the actuator drive circuit of the first embodiment shown in FIG. The operation panel of the zoom initial position selection means 68 is provided on an operation unit on the outer surface of the DSC 35 (see FIG. 19). Its external appearance is shown by two arrow keys 68a for selecting a zoom position, as shown in FIG. And a display section 68b for lighting and displaying the current zoom position. The user sets the still image shooting mode or the moving image shooting mode with the shooting mode selection dial 53, and selects the zoom position by pressing the arrow key 68a in each shooting mode, thereby setting the zoom position after the power is turned on. Can be freely selected by the photographer. The selected zoom position is stored in the initial zoom position storage means 67 as initial optical zoom magnification information.

  Hereinafter, the photographing method will be described with reference to the flowchart shown in FIG.

  First, when photographing a still image or a moving image, the photographing mode is selected by the photographing mode selection dial 53 (S701). In this state, the power button 37 of the DSC 35 is turned on (S702). Here, the microcomputer 36 determines which state the photographing mode is in (S703). When the shooting mode is the still image shooting mode, for example, when the initial zoom position is set at the telephoto end, the first-group lens drive actuator 22 that drives the first-group lens L1 rotates and shifts to the state shown in FIG. (S704).

  When the shooting mode is the moving image shooting mode, for example, when the initial zoom position is set to the wide-angle end, the first-group lens drive actuator 22 that drives the first-group lens L1 rotates, and furthermore, is a zooming lens. By moving the second group lens L2 to a predetermined position, the state shifts to the state shown in FIG. 12 (S705). When the first lens group L1 and the second lens group L2 move to predetermined positions, a shooting preparation state is set (S706).

  As described above, according to the eighth embodiment, in a DSC that can capture both a moving image and a still image, the photographer can determine the zoom magnification at the time of turning on the power when capturing a moving image and when capturing a still image. Because it can be set freely, for example, if you want to zoom in and shoot a still image instantly, shooting at the telephoto end where the time to reach the standby state is shorter than at the wide angle end immediately after the power is turned on Instantaneously, the inconvenience such as missing a photo opportunity is less likely to occur.

  The selected initial zoom position may be set in a stepless manner from the wide-angle end to the telephoto end. For example, the zoom initial position may be set to an intermediate position between the wide-angle end and the telephoto end shown in FIG. The same effect can be obtained.

  The field of use of the present invention is not particularly limited, but it can be used, for example, as a digital still camera.
