Description

  The present invention relates to an image pickup apparatus capable of moving image shooting and still image shooting. In particular, the present invention relates to an imaging apparatus with improved operability for moving image shooting.

  In recent years, digital still cameras (hereinafter referred to as DSCs) that can immediately check captured images are rapidly spreading. As a lens barrel for DSC, a so-called collapsible lens barrel is generally adopted in which the length of the lens barrel is shortened when not photographing in consideration of portability when not 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 (see, for example, Patent Document 1).

FIG. 30 is an exploded perspective view of a conventional retractable lens barrel (see, for example, Patent Document 2). The retractable 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 a single 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 moving lens frames 72 and 73, respectively. The movable lens frames 72 and 73 move in the optical axis (Z-axis) direction when the 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 is engaged with the gear 76. The driving force transmission gear 77 is connected to the output shaft of the 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. Accordingly, the moving lens frames 72 and 73 move along the shapes of the cam grooves 74 and 75, respectively, so that zooming is performed from the retracted state via the wide-angle end.

FIG. 12 is a cross-sectional view of the retractable lens barrel used in the imaging apparatus when the wide-angle end is used, and FIG. 13 is a flowchart for explaining the photographing operation of the imaging apparatus.

  The retractable lens barrel 1 will be described with reference to FIGS. As shown in the drawing, an XYZ three-dimensional orthogonal coordinate system in which the optical axis of the retractable lens barrel is the Z axis (the object side is positive) is set. L1 is a first group lens, L2 is a second group lens that moves on the optical axis (Z axis) and performs zooming, L3 is a third group lens for image blur correction, and L4 is a correction of image plane variation accompanying zooming and It is a four-group lens that 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. Yes. One end of two guide poles (guide members) 4 a and 4 b 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 above-described two guide poles 4a and 4b. The second group moving frame 5 is engaged with the feed screw 6a of the second group lens driving actuator 6 such as a stepping motor and the thread portion of the rack 7 provided on the second group moving frame 5. With this driving force, it moves in the optical axis direction and performs zooming.

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

  The fourth group moving frame 9 slides in the optical axis direction by being supported by two guide poles 11a and 11b sandwiched between the third group frame 8 and the master flange 10 and parallel to the optical axis. It is possible. The fourth group moving frame 9 is engaged with the feed screw 12a of the fourth group lens driving actuator 12 such as a stepping motor and the thread portion of the rack 13 provided on the fourth group moving frame 9. With this driving force, it moves in the optical axis direction, and correction and focusing of image plane variation accompanying zooming are performed.

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

  Next, a method for 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. The accuracy of the image blur correction lens L3 provided in the third group frame 8 is maintained. Further, the guide poles 4a and 4b are slidably inserted into the support portions 5a (non-rotating side) and 5b (main shaft side) provided on the second group moving frame 5, so that the second group moving frame 5 becomes a guide pole. Since the second group lens L2 held by the second group moving frame 5 is supported by 4a and 4b so as to be slidable in the optical axis direction, the second group lens L2 is more accurate than the image blur correction lens L3 provided on the third group frame 8. Is preserved.

  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 groups 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 group lens L3). The central axis L1a of the first group lens L1 and the central axis L2a of the second group lens L2 are parallel to each other.

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

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

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

  A gear 15 a is formed on a part of the inner peripheral surface of the substantially hollow cylindrical drive frame 15 on the image sensor 14 side. In addition, three protrusions 15b are formed at an interval of approximately 120 ° on the inner peripheral surface on the object side (positive side of the Z axis). The protrusion 15 b engages with the three circumferential grooves 3 a provided on the outer peripheral surface of the first group moving frame 3 on the image sensor 14 side, so that the drive frame 15 has an 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 to the inner peripheral surface of the drive frame 15 at intervals of 120 °.

  Three cam grooves 18a, 18b, and 18c are formed on the outer surface of the cylindrical cam frame 17 at approximately 120 ° intervals. FIG. 4 is a development view of the outer peripheral surface of the cam frame 17. Cam pins 16a, 16b and 16c of the drive frame 15 engage with cam grooves 18a, 18b and 18c of the cam frame 17, respectively. Each cam groove 18a, 18b, 18c has a portion 19a substantially parallel to the circumferential direction of the cam frame 17 on the imaging element 14 side (the negative side of the Z axis) and a cam frame on the object side (the positive side of the Z axis). 17 includes 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 group lens L1 stops in a state where it is retracted to the image pickup device 14 side (collapsed 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 through the portion 19b. When the cam pins 16a, 16b, and 16c are in the portion 19c, the first group lens L1 is extended to 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 that rotatably holds the drive gear shafts 20 at both ends of the spline-like drive gear 19 and a drive gear 19 A drive gear mounting portion (recessed portion) 17a that is recessed in a semi-cylindrical surface shape is formed so as 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. Yes. The drive gear 19 transmits the drive force of the drive unit 21 attached to the master flange 10 described later to a gear portion 15 a provided on the drive frame 15. Accordingly, when the drive gear 19 rotates, the drive frame 15 rotates around the optical axis. At this time, the cam pins 16a, 16b, 16c provided on the drive frame 15 are connected to 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 and 4b fixed to the first group moving frame 3 being inserted into the support portions 8a and 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 17 b of the cam frame 17. Further, the drive actuator 12 of the fourth group moving frame 9 is fixed to the mounting portion 10 a of the master flange 10. The drive unit 21 that transmits the drive force to the drive gear 19 includes a drive actuator 22 and a reduction gear unit 23 including a plurality of gears, and is fixed to the mounting portion 10 b of the master flange 10.

  The shutter unit 24 includes an aperture blade and a shutter blade that form a constant aperture diameter in order to control the exposure amount and exposure time of the image sensor 14.

  The origin detection sensor 25 for the second group moving frame 5 is a light detection sensor composed of a light emitting element and a light receiving element, and the position of the second group moving frame 5 in the optical axis direction, that is, the 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 17 c 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 the vicinity thereof. At this time, the blade 5c provided in the second group moving frame 5 passes through the front of the origin detection sensor 25, and detects the origin position by blocking light. 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 image sensor 14 near the drive motor 6. This state corresponds to the state of FIG.

  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 rotational 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 includes an image blur correction lens unit L3 for correcting image blur at the time of shooting, in a pitching direction which is a first direction (Y direction) and a yawing which is a 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, so that the image blur correcting lens unit L3 is substantially perpendicular to the optical axis Z. , Y drive in two directions.

  Next, an actuator drive circuit of an imaging 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 that controls the DSC 35. The microcomputer 36 drives and controls the first group lens drive actuator 22 via the drive control means 40 based on the signal from the power button 37 provided on the DSC 35, and the origin detection sensor 27 controls the origin position of the first group lens L1. Then, the first lens unit L1 is driven to a predetermined position. Further, the microcomputer 36 drives and controls the second group 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 group 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 drives and controls the fourth group lens drive actuator 12 via the drive control means 42, and the origin detection sensor 26 detects the origin position of the fourth group lens L4, and then the focus. Align.

  The shooting mode selection dial 53 is a rotary dial provided in the DSC 35 as shown in FIG. Each mode can be selected by rotating the photographing 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 captured image transmission mode 53g are provided.

  Next, the 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 retractable 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 unit 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 unit 46 performs digital signal processing such as noise removal and edge enhancement on the video signal converted into the digital signal by the A / D conversion unit 45. The frame memory 47 temporarily stores the image signal that has passed through the digital signal processing means 46. The image recording control means 48 controls the writing of the image once stored in the frame memory 47 to the image recording means 49 such as an internal memory or a recording medium. The captured image recorded in the image recording means 49 is displayed on the image display device 52 such as a liquid crystal monitor mounted on the DSC 35 via the frame memory 51 by a signal from the image display control means 50.

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

  First, the retractable lens barrel 1 shifts from the non-photographing (not in use) state shown in FIG. 10 to the photographing state shown in FIGS. 11 and 12, and can be photographed as the DSC 35. The operation up to here 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 in FIG. The power button 37 is pressed to turn on the DSC 35 main unit (S102). When the power supply is turned on, the first group lens driving actuator 22 that first drives the first group lens L1 is rotated, and the drive gear 19 is rotated via the reduction gear unit 23. As 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, and 18c. Then, 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 drive actuator 22 has rotated by a predetermined rotation amount, the first group movement frame 3 moves to a predetermined position, and then the first group lens drive actuator 22 The rotation stops. At this stop position, the cam pins 16a, 16b, and 16c reach a portion 19c that is substantially parallel to the circumferential direction of the cam frame 17 in the development 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 rotates and drives the rack 7 via the feed screw 6a, whereby the second group moving frame 5 is moved. It starts to move along the Z axis.

  Here, in the microcomputer 36 of the DSC 35, when the initial position of the zoom magnification after power-on is set near the wide angle end, the second group moving frame 5 initializes the origin detection sensor 25, 12 stops near the wide-angle end shown in FIG. 12, and the DSC 35 is ready for photographing.

  Next, the microcomputer 36 determines whether or not the shooting mode selection dial 53 is in the moving image shooting mode 53e (S103). If the movie shooting mode 53e is selected, movie 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. When the movie shooting is finished, the shutter button 39 is fully pressed (S106). Thereby, the moving image shooting is completed, and the shooting standby state is set. When the photographer fully presses the shutter button 39 in the shooting standby state, a still image or a moving image can be shot again according to the state of the shooting mode selection dial 53.

  Regarding the zooming operation at the time of shooting, it is possible to shoot at any 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 4 a and 4 b held by the support portions 8 a and 8 b of the third group frame 8. Move to a predetermined position. Therefore, even if the first group lens L1 and the second group lens L2 are tilted with respect to the optical axis, their tilt directions are the same as those for the image blur correcting lens group L3, and therefore, a predetermined optical performance is ensured. Can do.

  Next, the operation at the time of transition from the state at each photographing shown in FIGS. 11 and 12 to the state at the 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 finished. First, the second group moving frame 5 is moved to the image pickup device 14 side by the second group lens driving actuator 6 and is shown in FIG. It will be in the state shown. Next, the first lens group drive actuator 22 rotates, and the drive gear 19 is rotated in the reverse direction to the above via the reduction gear unit 23. As the drive gear 19 rotates, the drive frame 15 meshing with the drive gear 19 rotates around the optical axis, and at the same time moves toward the image sensor 14 by the cam grooves 18a, 18b, 18c. 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 stops after the first group movement frame 3 moves to a predetermined position. At this stop position, the cam pins 16a, 16b, and 16c reach a portion 19a that is substantially parallel to the circumferential direction of the cam frame 17 in the development view of the cam groove in FIG. As a result, the state shifts to the state shown in FIG. 10, and the retracted state is shortened by the length c as compared with the state at the time of photographing.

  Here, for the collapsing operation for changing the length of the retractable lens barrel 1 in the optical axis direction, the first group lens driving actuator 22 for driving the first group lens L1 is used, and for the zooming operation, the second group lens driving actuator 6 is used alone. It is used in. Therefore, since the zooming operation in actual photographing is performed in the state where the first group lens L1 is 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 from FIG. Zooming can be performed by moving the second group lens L2 to an arbitrary position in FIG. Therefore, when performing shooting such as zooming, unlike the conventional retractable lens barrel shown in FIG. 30, it is necessary to perform the lens barrel extension operation and retraction operation according to the zoom magnification. Absent. In the conventional retractable lens barrel of FIG. 30, during the zooming operation, one drive actuator 79 is rotated, the cam cylinder 71 is rotated via the reduction gear train 78, and the moving lens frames 72 and 73 are simultaneously moved. Because it was driven, the zooming speed was slow and the driving sound was loud. The retractable lens barrel 1 of the present invention uses a stepping motor as the second group lens drive actuator 6, and directly drives the second group moving frame 5 via a feed screw 6a attached to the stepping motor. Fast feed speed and low noise. Therefore, the photographer can change the angle of view instantly, and can perform usage methods that are unsuitable for conventional DSC, such as chasing a subject or shooting a moving image with sound.

  As described above, according to the first embodiment, in a DSC that can shoot both moving images and still images, when the moving image shooting mode is selected and the DSC is turned on automatically, Movie recording starts. Therefore, it is possible to obtain an optimum DSC for moving image shooting, in which moving image shooting can be started instantaneously after chasing the subject.

  Further, in the DSC equipped with a lens corresponding to a 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. The remarkable effect that it becomes possible to shorten the full length when not in use while minimizing the above is obtained.

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

  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 can also be configured so that video recording does not start until the button is pressed. In this case, it is possible to avoid a malfunction that the power is inadvertently turned on and the moving image shooting is started.

(Embodiment 2)
Next, an imaging apparatus according to Embodiment 2 of the present invention will be described with reference to FIG. FIG. 14 is a flowchart for describing a photographing operation of the imaging apparatus according to the second embodiment. In addition, the same code | symbol is attached | subjected about the component same as Embodiment 1, and the description is abbreviate | omitted.

  The operation will be described below using the flowchart shown in FIG. First, by turning on the power of the DSC 35 main body (S201), the DSC 35 enters a photographing standby state (S202). Next, when moving image shooting is performed, the shooting mode selection dial 53 is used to select the moving image shooting mode 53e (S203). When the movie shooting mode 53e is selected, movie shooting is automatically started (S204). In this case, it is not necessary to press the shutter button 39 or the like, and moving image shooting starts instantaneously. When ending moving image shooting, the shutter button 39 is fully pressed (S205), and shooting is ended.

  As described above, according to the second embodiment, in the DSC capable of shooting both moving images and still images, when the moving image shooting mode is selected while the power is on, moving image shooting starts automatically. To do. Therefore, there is no need to press a separate shutter button or the like to start moving image shooting, and moving image shooting can be started instantaneously. As a result, the chance of missing important shutter opportunities can be reduced.

  In the second embodiment, the moving image shooting is automatically started when the moving image shooting mode is selected. However, until the photographer presses the shutter button by the selection operation of the menu. It can also be configured not to start moving image shooting. In this case, it is possible to avoid a malfunction that the shooting mode selection dial is inadvertently turned to start moving image shooting.

(Embodiment 3)
Next, an imaging apparatus according to Embodiment 3 of the present invention will be described with reference to FIG. FIG. 15 is a flowchart for explaining the photographing operation of the imaging apparatus according to the third embodiment. In addition, the same code | symbol is attached | subjected about the component same as Embodiment 1, and the description is abbreviate | omitted.

  The operation will be described below using 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 in FIG. The power button 37 is pressed to turn on the power of the DSC 35 (S302). When the power is turned on, the first group lens actuator 22 and the second group lens actuator 6 rotate, and the first group lens L1 and the second group lens L2 move in the direction of the optical axis Z by a predetermined amount. The DSC 35 stops in the vicinity and is ready for photographing.

  Next, the microcomputer 36 determines whether or not the shooting mode selection dial 53 is in the moving image shooting mode 53e (S303). When the moving image shooting mode 53e is selected, the process proceeds to the next step (S305), and when the still image shooting modes 53b to 53d are selected, the 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). The still image is written to a recording medium such as a memory card via the frame memory 47 and the image recording means 49, and the still image shooting is finished (S307). When the still image shooting is completed, the mode automatically shifts to the moving image shooting mode and the moving image shooting is started (S308). When the movie shooting is finished, the shutter button 39 is fully pressed (S309). Thereby, the moving image shooting is completed, and the shooting standby state is set.

  As described above, according to the third embodiment, in a DSC capable of shooting both moving images and still images, when moving image shooting is performed with the moving image shooting mode selected, immediately before the start of moving image shooting. In addition, since a still image having a higher resolution than that of the moving image is taken, a remarkable effect that a subject at the same time can be taken continuously can be obtained. That is, the conventional DSC with a retractable lens barrel can solve the problem that a moving image with sound and a still image cannot be taken at the same time.

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

(Embodiment 4)
Next, an imaging apparatus according to Embodiment 4 of the present invention will be described with reference to FIGS. FIG. 16 is a diagram illustrating a directory structure of the file system of the imaging apparatus according to the fourth embodiment, FIG. 17 is a diagram illustrating data of an association information file of the imaging apparatus, and FIG. 18 is a flowchart illustrating a shooting operation of the imaging apparatus. It is. In addition, the same code | symbol is attached | subjected about the component same as Embodiment 1, and the description is abbreviate | omitted.

  A file management method for captured images of the DSC 35 will be described with reference to FIGS. 16 and 17. A recorded image folder 54 (folder name “Picture”) is formed on a recording medium (not shown) on which the photographed photographed image is recorded, and an associated information file folder 55 (folder name “Index”), a still image, 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 captured still image is stored is created, for example, with the name “Still001.jpg”. In the moving image folder 57, a moving image file 60 in which a captured moving image is stored is created, for example, with a name “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 with a still image is stored is created, for example, with the name “Index001.html”. That is, in the file “Index001.html”, as shown in FIG. 17, the relative path on the directory between “Still001.jpg” of the still image file 59 and “Movie001.avi” of the moving image file 60. By recording (that is, association information), association between a still image and a moving image captured at the same time is realized.

  The operation will be described below using 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 (S401). At this time, the lens barrel 1 is in a non-photographing state in FIG. The power button 37 is pressed to turn on the power of the DSC 35 (S402). When the power is turned on, the first group lens actuator 22 and the second group lens actuator 6 rotate, and the first group lens L1 and the second group lens L2 move in the direction of the optical axis Z by a predetermined amount. The DSC 35 stops in the vicinity and is ready for photographing.

  Next, the microcomputer 36 determines whether or not the shooting mode selection dial 53 is in the moving image shooting mode 53e (S403). When the moving image shooting mode 53e is selected, the process proceeds to the next step (S405), and when the still image shooting modes 53b to 53d are selected, the 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 moving image shooting (S406). The still image is written to a recording medium such as a memory card via the frame memory 47 and the image recording means 49, and the still image shooting is finished (S407). At this time, when recording on a memory card or the like for the first time, after creating the still image folder 56, “Still001.jpg” is created as a still image file 59 under the hierarchy, 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 image is stored therein. Next, when the still image shooting is completed, the mode automatically shifts to the moving image shooting mode, and the moving image shooting is started (S408). When the shooting of the moving image ends, the shutter button 39 is fully pressed (S409). As a result, shooting is terminated and a shooting standby state is set. The captured moving image is written to a memory card or the like via the frame memory 47 and via the image recording means 49. At this time, when recording for the first time on a memory card or the like, after creating the moving image folder 57, “Movie 001.avi” is created as the moving image file 60 under the hierarchy, 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, together with the recording of the still image file 59 and the moving image file 60, after creating the association information file folder 55, "Index001.html" is created as the association information file 58 under the hierarchy, as shown in FIG. Association information is recorded.

  As described above, according to the fourth embodiment, in a DSC that can shoot both moving images and still images, a moving image and a still image with a higher resolution than that of the moving image immediately before the start of moving image shooting. Can be taken, and an association information file can be created to easily associate a moving image and a still image created at almost the same time, so file management on a recording medium such as a memory card is easy. A remarkable effect is obtained.

  When a still image is shot in the still image shooting mode (program mode P53b, aperture priority mode A53c, shutter priority mode S53d), a still image file 59 is created in the shot still image. The still image is saved. At this time, the corresponding association information file 58 is also 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 apparatus according to Embodiment 5 of the present invention will be described with reference to FIGS. FIG. 19 is a schematic diagram of an image display unit of the imaging apparatus according to the fifth embodiment, FIG. 20 is a diagram illustrating a moving image playback menu in the imaging apparatus, and FIG. 21 is a flowchart illustrating an image playback operation in the imaging apparatus. It is. In addition, the same code | symbol is attached | subjected about the component same as Embodiment 1, and the description is abbreviate | omitted.

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

  Hereinafter, a method for reproducing the captured image will be described with reference to the flowchart shown in FIG. First, when playing back a moving image, the playback 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 stored in the file “Still001.jpg” is displayed on the image display device 52 (S502). Next, a selection is made as to whether or not to reproduce a moving image shot 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 the reproduction state of the moving image, and an arrow key mark 69b indicating which arrow key 64 should be operated in order to reproduce the moving image. When displaying 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 playing a moving image, pressing the down arrow key 64 (the direction in which “SET” is present) starts playing the moving image associated with the still image displayed at that time ( S504). For example, when a moving image playback instruction is given while a still image stored in the still image file “Still001.jpg” is displayed, the data stored in “Index001.html” in the association information file 58 is used. Then, the moving image stored in the moving image file “Movie001.avi” is reproduced (S505).

  If there is no moving image associated with the still image, that is, the shooting mode selection dial 53 is used to select a still image shooting mode (program mode P53b, aperture priority mode A53c, shutter priority mode S53d). When the still image is displayed, the moving image reproduction menu 69 is not displayed. A file in which a still image having no associated moving image is stored corresponds to “Still004.jpg” and “Still005.jpg” in the still image file 59 stored in the still image folder 56 shown in FIG. To do. That is, there is an association information file 58 named “Index004.html” and “Index005.html” corresponding to these, respectively, but the moving images named “Movie004.avi” and “Movie005.avi” corresponding to these respectively. The image file 60 does not exist.

  In addition, when a still image in which an associated moving image exists is displayed, a mark 69c indicating that a moving image exists is displayed on the upper right of the image display device 52.

  As described above, according to the fifth embodiment, in the DSC capable of capturing both moving images and still images, the association information file for associating the moving images with the still images is read when the captured images are reproduced. Thus, it is possible to easily reproduce a moving image that is shot at the same time as the still image and associated with the still image. Further, by marking a still image, it is possible to instantly determine whether or not there is a moving image associated with the still image, so that a significant effect of facilitating the reproduction of the moving image is obtained. It is done.

(Embodiment 6)
Next, an imaging apparatus according to Embodiment 6 of the present invention will be described with reference to FIG. FIGS. 22A and 22B are diagrams illustrating thumbnail display of still images in the sixth embodiment.

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

  When thumbnails of the 1st to 9th still images are displayed on the image display device 52 as shown in FIG. 22B, the images are usually displayed side by side in order of photographing time. In this case, as described in the fifth embodiment, the mark 69c indicating that the associated moving image exists is displayed on the upper right of each image. However, when the images are arranged in the order of the shooting times, those having associated moving images (No. 3 to 7) and those having no associated moving images (No. 1 to 2, 8 to 9) are mixed. Displayed, it is very difficult to see and it is difficult to select a desired image.

  On the other hand, as shown in FIG. 22 (a), the captured images are rearranged to display still images in which moving images associated with the first half 1-5 are displayed and associated with the second 6-9. A still image without the displayed 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 displaying still images as thumbnails, images that were conventionally difficult to see because they were displayed in order of shooting time are associated with still images that have associated moving images. By classifying and displaying still images that do not have moving images, selection and reproduction of moving images is facilitated.

  In this embodiment, a still image in which the associated moving image exists and a still image in which the associated moving image does not exist are displayed in succession. It may be inserted. Further, although the case of thumbnail display has been described, the same effect can be obtained by changing the order in which still images are displayed, even if the still images are sequentially displayed one by one.

(Embodiment 7)
Next, an imaging apparatus according to Embodiment 7 of the present invention will be described with reference to FIGS. FIG. 23 is a block diagram of a data transmission unit in the imaging device according to the seventh embodiment, FIG. 24 is a diagram illustrating a transmission image transmission selection menu of the imaging device, and FIG. 25 is a diagram illustrating an image transmission operation of the imaging device. It is a flowchart. In addition, the same code | symbol is attached | subjected about the component same as Embodiment 1, and the description is abbreviate | omitted.

  FIG. 23 is a block diagram of a data transmission unit provided in the imaging apparatus. The image transmission control unit 61 passes the captured image read from the image recording unit 49 via the frame memory 51 and the captured image transmission unit 62. And transmitted 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 an image to send.

  Hereinafter, the transmission method of the captured image will be described using 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, for example, a still image stored in the “Still001.jpg” file is displayed on the image display device 52 (S602). Next, it is selected 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 are displayed. Three menus indicating transmission of 66c are displayed. When another still image is reproduced, the page is turned by the arrow key 64, and the still image stored in, for example, the “Still002.jpg” file is displayed. In the case of transmission, an image to be transmitted is selected from the image transmission selection menu 66 (S604). When only a still image is transmitted, for example, still image data in a “Still001.jpg” file is transmitted (S605). When transmitting a moving image, based on the data in the “Index001.html” file of the association information file 58, for example, the moving image data in the “Movie001.avi” file associated with the 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 “Movie001” are based on the data in the “Index001.html” file of the association information file 58. .Avi "and the moving image data in" avi "are transmitted (S607).

  Here, when there is no moving image associated with the still image, that is, the shooting mode selection dial 53 is used to select and shoot a still image shooting mode (program mode P53b, aperture priority mode A53c, shutter priority mode S53d). When the still image is displayed, the two menus indicating the transmission of the moving image 66b, the still image, and the moving image 66c are not displayed on the image transmission selection menu 66, and only the menu indicating the transmission of the still image 66a is displayed.

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

  In addition, as described in Embodiment 6, still images may be displayed as thumbnails. In this case, the still images may be displayed side by side in the order of shooting time. However, the desired images can be sorted and sorted into still images that have associated moving images and still images that have no associated moving images. It becomes easy to select the image.

  As described above, according to the seventh embodiment, in the DSC capable of capturing both moving images and still images, the association information file for associating the moving images with the still images is read when the captured images are transmitted. Thus, it is possible to easily select and transmit a moving image shot at the same time as a still image and associated with the still image.

  In this embodiment, the image transmission unit including the antenna is built in the imaging apparatus. However, only a modem or the like may be built in, and the image may be transmitted by connecting to a mobile phone or the like.

  In this embodiment, a method of selecting the transmission method of the captured image is adopted. However, the initial setting is a method of automatically transmitting only a still image with a small file capacity, and a moving image is transmitted only when the user needs it. May be changed so as to enable transmission.

(Embodiment 8)
Next, an imaging apparatus according to Embodiment 8 of the present invention will be described with reference to FIGS. FIG. 26 is a block diagram showing the configuration of the actuator drive circuit of the imaging apparatus according to the eighth embodiment, FIG. 27 is a schematic diagram showing the operation panel of the zoom initial position selection means of the imaging apparatus, and FIG. A sectional view of the retractable lens barrel used at the intermediate position between the wide-angle end and the telephoto end, and FIG. 29 is a flowchart for explaining the photographing operation of the image pickup apparatus. In addition, the same code | symbol is attached | subjected about the component same as Embodiment 1, and the description is abbreviate | omitted.

  The block diagram showing the configuration of the actuator drive circuit of FIG. 26 is obtained by adding a zoom initial position storage means 67 and a zoom initial position selection means 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 in the operation unit on the outer surface of the DSC 35 (see FIG. 19). As shown in FIG. 27, the appearance panel includes two arrow keys 68a for selecting the zoom position and And a display unit 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. Can be freely selected by the photographer. The selected zoom position is stored in the zoom initial position storage unit 67 as initial optical zoom magnification information.

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

  First, when shooting a still image or a moving image, the shooting mode selection dial 53 is used to select a shooting mode (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 zoom initial position is set to the telephoto end, the first group lens driving actuator 22 that drives the first group lens L1 rotates and shifts to the state shown in FIG. (S704).

  Further, when the shooting mode is the moving image shooting mode, for example, when the zoom initial position is set to the wide-angle end, the first group lens driving actuator 22 that drives the first group lens L1 rotates, and is also 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 group lens L1 and the second group lens L2 move to the predetermined positions, a shooting preparation state is set (S706).

  As described above, according to the eighth embodiment, in the DSC capable of shooting both moving images and still images, the photographer can set the zoom magnification at power-on for moving image shooting and still image shooting. Since it is possible to set freely, for example, if you want to zoom in instantly and shoot a still image, shooting at the telephoto end is shorter than the wide-angle end and it takes less time to reach the standby state. Since it becomes possible instantly, inconveniences such as missing a photo opportunity are less likely to occur.

  Note that the initial zoom position to be selected may be set steplessly in the range from the wide-angle end to the telephoto end. For example, it may be set to an intermediate position between the wide-angle end and the telephoto end shown in FIG. However, the same effect can be obtained.

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