Description

Imaging device

  The present invention relates to a method for displaying an image taken by an imaging apparatus.

  A digital camera, which is one of recent imaging apparatuses, is equipped with a horizontally long liquid crystal monitor 33 shown in FIG. 24B on the back side of the main body shown in FIG. This is very convenient for the photographer.

  In recent years, the number of pixels such as CCDs used as an image sensor of a digital camera has been remarkably increasing, and an improvement in image quality can be seen.

  Moreover, in the recent transaction market, the digital camera market has become larger than the conventional silver salt camera.

  In addition, in the case of personal use with a conventional silver salt camera, the main method is to print out and view a photographed image on a service-size hard copy, but in recent years digital cameras, especially DSC (Digital In Still Camera), not only the number of pixels is increased, but also the appreciation method such that the general user personally prints out to the desired size such as A4 size due to the spread of printers etc. It has become.

  Under such circumstances, if camera shake occurs at the time of shooting, it is conceivable that degradation of image quality will be noticeable when printing out to a large size, making it unbearable for viewing.

That is, the effect of camera shake correction is great not only for DVC for moving image shooting but also for DSC for still image shooting.

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 is a hardware configuration diagram of an imaging apparatus according to the first embodiment, FIG. 2 is a hardware configuration diagram of a camera shake correction apparatus, FIG. 3 is an exploded perspective view showing an image blur correction mechanism, and FIG. 4 is an image blur correction mechanism. FIG. 5 is a diagram illustrating the magnitude of the current value of the actuator, and FIG. 6 is a diagram illustrating rearrangement of the captured image data in the vertical and horizontal directions.

  The solid-state imaging device (CCD) 4 is an imaging device that converts an image incident through the imaging optical system 3 into an electrical signal, and is driven and controlled by a CCD drive control means 5. The analog signal processing unit 6 is a processing unit that performs analog signal processing such as gamma processing on the video signal obtained by the solid-state imaging device 4. The A / D conversion means 7 is a conversion means for converting the analog video signal output from the analog signal processing means 6 into a digital signal.

  The digital signal processing unit 8 is a signal processing unit that performs digital signal processing such as noise removal and edge enhancement on the video signal converted into a digital signal by the A / D conversion unit 7. The frame memory 9 temporarily stores the image signal that has passed through the digital signal processing means 8. The image once recorded in the frame memory 9 is controlled to be written into the image recording means 11 such as an internal memory or a recording medium in accordance with a command from the image recording control means 10.

  The imaging optical system 3 is an imaging optical system including three lens groups L1, L2, and L3. The L2 lens group is used as a correction lens group, and moves in a plane perpendicular to the optical axis, thereby decentering the optical axis. Plays the role of correcting the movement of the image. The yawing drive correction unit 12x and the pitching drive correction unit 12y drive-control the L2 lens group, which is a correction lens group, in two directions X and Y directions orthogonal to the optical axis of the imaging optical system 2.

  Hereinafter, the X direction is the yawing direction and the Y direction is the pitching direction. The position detection means 13 is a detection means for detecting the position of the L2 lens group, and forms a feedback control loop for driving and controlling the L2 lens group together with the yawing drive control means 12x and the pitching drive control means 12y. The L2 lens group, the yawing drive control unit 12x, and the pitching drive control unit 12y form a motion correction unit that controls the optical axis of the imaging light.

  The angular velocity sensors 14x and 14y are sensors for detecting the movement of the imaging apparatus itself including the imaging optical system 2, and the direction of movement of the imaging apparatus 1 is based on the output when the imaging apparatus 1 is stationary. To output both positive and negative angular velocity signals. Two angular velocity sensors 14x and 14y are provided for detecting movements in two directions of yawing and pitching, respectively. As described above, the angular velocity sensors 14x and 14y have a function of a motion detection unit that detects the motion of the imaging apparatus 1 due to camera shake and other vibrations. The angular velocity sensor output is converted into a digital signal by A / D conversion means 15x and 15y through filter processing, amplifier processing, and the like, and is given to the microcomputer 2.

  The microcomputer 2 performs filtering, integration processing, phase compensation, gain adjustment, clip processing, etc. on the output signals of the angular velocity sensors 14x, 14y taken in via the A / D conversion means 15x, 15y, and is necessary for motion correction A drive control amount (control signal) of the L2 lens group is obtained. The control signal is output to the yawing drive control means 12x and the pitching drive control means 12y via the D / A conversion means 16x and 16y. Therefore, the yawing drive control means 12x and the pitching drive control means 12y correct the image motion by driving the L2 lens group based on the control signal.

  FIG. 3 is an exploded perspective view showing an example of an image blur correction mechanism 20 that drives and controls the L2 lens group in a direction orthogonal to the optical axis in the imaging optical system 3. The L2 lens group is fixed to a pitching moving frame 21, and this pitching moving frame 21 is held so as to be slidable in the Y direction via two pitching shafts 23 a and 23 b with respect to the yawing moving frame 22. The coils 24x and 24y are fixed to the pitching movement frame 21. The yawing movement frame 22 is slidably held in the X direction with respect to the fixed frame 25 via yawing shafts 26a and 26b.

  The magnet 27x and the yoke 28x are held by the fixed frame 25 and constitute an actuator 29x together with the coil 24x. Similarly, the magnet 27y and the yoke 28y are held by the fixed frame 25 and constitute an actuator 29y together with the coil 24y. The light emitting element 30 is fixed to the pitching movement frame 21. The light receiving element 31 is an element that receives the projection light of the light emitting element 30 and detects a two-dimensional position coordinate, and is fixed to the fixed frame 25.

  The yawing current value detecting means 17x shown in FIG. 2 is a detecting means for detecting a current value flowing through the coil 24x when the yawing actuator 29x is operated. Similarly, the pitching current value detection means 17y is a means for detecting a current value flowing through the coil 24y when the pitching actuator 29y is operated.

  A current value detection method by the yawing current value detection means 17x and the pitching current value detection means 17y will be described. In photographing in a normal posture as shown in FIG. 24A, the posture of the image blur correction mechanism 20 is as shown in FIG.

  At this time, in order to hold the L2 lens group at the optical axis center with respect to the Y direction, the weight of the L2 lens group, the pitching holding frame 21, and the coils 24x and 24y is applied in the gravity direction (Y direction). It is necessary to pass an electric current to lift the weight. The current value at that time is Iy1 shown in FIG.

  Further, regarding the X direction, since it is not necessary to consider the weight of the L2 lens group that is held at the center of the optical axis, the value of the current that flows through the coil 24x is Ix2, which is smaller than Iy1. Conversely, in the photographing posture rotated by 90 ° as shown in FIG. 25A, the posture of the image blur correction mechanism 19 is as shown in FIG. 4B.

  At this time, in order to hold the L2 lens group at the center of the optical axis in the X direction, in addition to the L2 lens group, the pitching holding frame 21, and the coils 24x and 24y described above, the weight of the yawing holding frame 22 is reduced in the gravity direction ( Therefore, it is necessary to pass a current to lift the weight of the coil 24x. The current value at that time is Ix1 which is larger than Iy1.

Regarding the Y direction, since it is not necessary to consider the weight of the L2 lens group that is held at the center of the optical axis, the value of the current that flows through the coil 24y is Iy2, which is smaller than Ix1. As described above, since the current value flowing through the coils 24x and 24y is determined depending on the posture for photographing, the image blur correction mechanism 20 and the lens barrel 19 equipped with the image blur correction mechanism are detected by detecting this current value. Furthermore, it becomes possible to detect the attitude of the imaging apparatus 1.

  The operation of the imaging apparatus of the present embodiment configured as described above will be described below.

  When the photographer takes a picture, the camera speed generated in the image pickup apparatus 1 is detected by the angular velocity sensors 14x and 14y, and the microcomputer 2 gives a command to cancel the camera shake, and the coils 24x and 24y of the pitching moving frame 21 are respectively given. When a current is supplied from an external circuit, the pitching moving frame 21 moves in the two directions X and Y planes perpendicular to the optical axis Z by the magnetic circuit formed by the actuators 27x and 27y. In addition, since the position of the pitching moving frame 21 is detected by the light receiving element 29, highly accurate position detection can be performed. That is, by moving the L2 lens group in two planes orthogonal to the optical axis by the image blur correction mechanism 20, it is possible to correct an image incident on the image pickup device 4 via the image pickup optical system 2, and to prevent camera shake. It is possible to take a good suppressed image.

  Next, a method for determining the shooting posture of the imaging apparatus will be described in the case where the photographer shoots a landscape object such as a landscape in the state shown in FIG. The attitude of the imaging device 1 is determined by the detection values of the yawing current value detection means 17x and the pitching current value detection means 17y. When photographing in this posture (at 0 °), the current value flowing through the coil 24x of the camera shake correction mechanism 20 is Ix2 and the current value flowing through the coil 24y by the yawing drive current value detection unit 17x and the pitching drive current value detection unit 17y. It can be seen that Iy1.

  As a result, the microcomputer 2 determines the posture of the imaging device 1. The subject can be photographed by pressing the shutter button 35 in this state, and the photographed image is recorded in the image recording means 11. The recorded image to be recorded is normal A × B pixel data as shown in FIG.

  Next, a case where the photographer shoots a vertically long subject such as a person in the state shown in FIG. The attitude of the imaging device 1 is determined by the detection values of the yawing current value detection means 17x and the pitching current value detection means 17y. When photographing in this posture (90 ° posture), the current value Ix1 flowing in the coil 24x of the camera shake correction mechanism 20 and the current value Iy2 flowing in the coil 24y are detected by the yawing drive current value detection means 17x and the pitching drive current value detection means 17y. I understand that.

  As a result, the microcomputer 2 determines the posture of the imaging device 1. The subject can be photographed by pressing the shutter button 35 in this state, and the photographed image is recorded in the image recording means 11. As shown in FIG. 6B, the recorded image is originally data of A × B pixels, but is recorded in the image recording means 11 because the image pickup apparatus 1 is taken by rotating 90 °. At this time, the photographed image is rotated by 90 °, and is output from the frame memory 9 in a state where the vertical and horizontal directions are rearranged to form B × A pixels.

  As described above, according to the first embodiment, by mounting the camera shake correction mechanism, it is possible to shoot a good image without camera shake. Furthermore, since the driving current value detection means of the actuator makes it possible to determine the shooting posture of the imaging device, the subject and the shot image are aligned vertically and horizontally without separately providing a detection sensor that causes an increase in cost. The captured image can be recorded by adjusting the vertical and horizontal directions.

As a result, when a captured image is separately displayed on a display device or the like, it is not affected by the orientation of the imaging device used by the photographer, and no special operation such as rotating the captured image is required. The captured image can be displayed in the posture.

  In the present embodiment, both pitching and yawing are used as the current value detection means. However, it is possible to specify the attitude of the imaging device only by detecting one of the current values. However, as described in the present embodiment, by detecting both current values, even if an abnormality occurs in the current value measuring means on one side, it is possible to determine more accurately. Needless to say, with respect to this posture detection means, in an imaging apparatus that does not include a camera shake correction mechanism, an effect similar to that of the present embodiment can be obtained by separately attaching an angle sensor or the like.

  As described in the present embodiment, the imaging apparatus main body may be provided with a selection unit that can select a method for rearranging the recorded images according to the photographing posture and a method for rearranging the recording images as usual.

  As for the photographed image, the still image has been described, but a moving image, a simple moving image, or the like can be similarly handled.

  The photographing posture in which the imaging device is rotated by 90 ° is not limited to this posture, and may be a state in which the photographing device is further rotated by 180 ° from this posture.

  In addition, the shape of the imaging device is not limited to that described in this embodiment.

  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a diagram for explaining the attitude determination signal of the image pickup apparatus recorded in the photographed image. In addition, what was demonstrated so far attaches | subjects the same code | symbol and the description is abbreviate | omitted.

  In the captured image, an attitude determination signal 36 for determining a difference in imaging attitude of the imaging apparatus 1 is recorded simultaneously. The posture determination signal when the shooting posture is 0 ° is 36 (0), and the posture determination signal when the shooting posture is 90 ° is 36 (1).

  The operation of the imaging apparatus according to the second embodiment configured as described above will be described below.

  A case where the photographer shoots a landscape object such as a landscape in the state shown in FIG. As described in the first embodiment, the posture of the imaging device 1 is determined based on the magnitude of the current flowing in the coils 24x and 24y of the image blur correction mechanism 20. The subject can be photographed by pressing the shutter button 35 in this state, and the photographed image is recorded in the image recording means 11. At this time, the image recording control means 10 adds an attitude determination signal 36 (0) indicating that the imaging attitude of the imaging apparatus 1 is 0 ° to the image signal output from the frame memory 9. The posture determination signal 36 is recorded, for example, in the header or footer portion of the image signal. The timing for recording the attitude determination signal 36 may be in either the frame memory 9 or the image recording means 11.

  Next, a case where the photographer shoots a vertically long subject such as a person in the state shown in FIG. The subject can be photographed by pressing the shutter button 35 in this state, and the photographed image is recorded in the image recording means 11. At this time, the image recording control means 10 adds an attitude determination signal 36 (1) indicating that the imaging attitude of the imaging apparatus 1 is 90 ° to the image signal output from the frame memory 9.

As described above, according to the second embodiment, the photographing posture of the imaging apparatus can be determined, and the posture determination signal of the imaging device can be recorded together with the photographed image. As a result, when the captured image is separately displayed on the display device, the display method is controlled based on the orientation determination signal recorded in the captured image, so that the orientation of the imaging device used by the photographer is not affected. In addition, the photographed image can be displayed in the original posture of the subject without any special operation such as rotating the photographed image.

  In this embodiment, the method of adding the signals (0) and (1) is used as the posture determination signal, but the present invention is not limited to this method.

  Next, in the first and second embodiments of the present invention, other embodiments will be described with reference to FIG. FIG. 8 is a hardware configuration diagram of the imaging apparatus according to the present embodiment. In addition, what was demonstrated so far attaches | subjects the same code | symbol and the description is abbreviate | omitted.

  The imaging apparatus 1 has a transmission unit 51 such as a modem added to the hardware configuration shown in FIG. 1, and the captured image recorded in the image recording unit 11 is framed by the image transmission control unit 50. The data is read out to the memory 45 and transmitted through the transmission means 51 via a public telephone line or the like.

  By transmitting captured images through the transmission means in this way, home images, other people's computers and portable information terminals, and even images taken by users are stored on the server of the album site's operating company. A photographed image can be instantly and easily transmitted to an “album site” that is disclosed on a dedicated Web page to the user.

  Note that the image transmission method may be a method using a mobile phone or the like as long as it can transmit an image, and is not limited to the method of this embodiment.

  Next, a third embodiment of the present invention will be described with reference to FIGS. FIG. 9 is a flowchart for recording a captured image, and FIG. 10 is a diagram for explaining a file management method of the imaging apparatus. In addition, what was demonstrated so far attaches | subjects the same code | symbol and the description is abbreviate | omitted.

  A file management method of the imaging apparatus 1 will be described. A captured image folder 90 is formed on a recording medium (not shown), and a still image folder 91 and a moving image folder 92 are formed thereunder. Further, a horizontal posture image folder 93 and a vertical posture image folder 94 are formed under the still image folder 91 and the moving image folder 92 in accordance with the photographing posture of the imaging apparatus 1.

  In the still image shooting mode, the shot still image is stored as a still image image file 95 in either the horizontal posture image folder 93a or the vertical posture image folder 94a.

  In the moving image shooting mode, the captured moving image is stored as a moving image file 96 in either the horizontal posture image folder 93b or the vertical posture image folder 94b.

  Hereinafter, the method for recording the captured image will be described with reference to the flowchart of FIG.

  In step S2, the microcomputer 2 determines whether the photographer has selected either a still image or a moving image shooting mode.

If the still image shooting mode is set, the microcomputer 2 sets the recording destination directory in the still image folder 91 in step S3. Next, in step S4, the posture of the image pickup apparatus is determined by the posture determination means. In step S5, the horizontal posture image folder 93a is set in the horizontal posture (the state shown in FIG. 24A). (The state of FIG. 25A) sets the vertical posture image folder 94a. Next, in step S6, it waits for a shutter button (not shown) to be pressed, and when it is pressed, still image shooting is performed in step S7, and recording is ended in step S8. The still images taken at this time are stored in the horizontal posture image folder 93a or the vertical posture image folder 94a as image files 95a and 95b.

  Next, when the moving image shooting mode is set, the microcomputer 2 sets the recording destination directory in the moving image folder 92 in step S9. Next, in step S10, the posture of the imaging apparatus is determined by the posture determination unit. In step S11, the horizontal posture image folder 93b is set for the horizontal posture, and the vertical posture image folder 94b is set for the vertical posture. Next, in step S12, the process waits for the shutter button to be pressed. If the shutter button is pressed, moving image shooting is performed in step S13, and recording ends in step S8. The moving images taken at this time are stored in the horizontal posture image folder 93b or the vertical posture image folder 94b as image files 96a and 96b.

  When playing back a recorded image, the user selects either a still image or a moving image, and further selects either a horizontal posture image or a vertical posture image, so that a desired captured image can be instantaneously and Easy to choose.

  As described above, according to the third embodiment, a moving image, a still image, and a captured image in the horizontal posture and the vertical posture of the imaging apparatus can be grouped and stored. As a result, a desired captured image can be selected and reproduced instantly and easily compared to the conventional case where a plurality of captured images are not grouped and stored in the same folder in the order of shooting time. Furthermore, data exchange with a personal computer is convenient.

  In the present embodiment, two images, ie, a still image and a moving image, have been described. Needless to say, a still image includes a plurality of captured images taken in the continuous shooting mode. The moving image may be a simple moving image.

  Next, a fourth embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a hardware configuration diagram of the imaging apparatus according to the fourth embodiment, and FIG. 12 is a diagram illustrating a method for displaying a captured image. In addition, what was demonstrated so far is attached | subjected the same code | symbol, and the description is abbreviate | omitted.

  The captured image recorded in the image recording means 11 is displayed by the image display control means 32 on the image display means 33 such as a liquid crystal monitor mounted on the imaging device 1 via the frame memory 45.

  The operation of the image pickup apparatus according to the fourth embodiment configured as described above will be described below.

  A method for displaying a photographed image when the photographer photographs a landscape object such as a landscape in the state shown in FIG. As described in the second embodiment, a posture discrimination signal 36 (0) indicating that the photographing posture is 0 ° is added to the photographed image photographed in this posture, and image recording is performed. Recorded in the means 11.

  When this captured image is displayed on the liquid crystal monitor 33 mounted on the imaging apparatus 1, the display can be displayed by pressing the display button 34 and selecting a desired captured image.

  At this time, the image display control means 32 controls the display method of the captured image based on the attitude determination signal 36 (0) of the imaging device 1 recorded in the captured image to be displayed. That is, since this photographed image was photographed with an attitude of 0 °, it is displayed in the normal use state of the imaging apparatus 1 as shown in FIG.

  Next, a display method when the photographer photographs a vertically long subject such as a person in the state shown in FIG. As described in the second embodiment, the posture determination signal 36 (1) indicating that the shooting posture is 90 ° is added to the shot image shot in this posture, It is recorded in the image recording means 11.

  When the captured image is mounted on the imaging apparatus 1 and displayed on the liquid crystal monitor 33, the captured image can be displayed by pressing the display button 34 and selecting a desired recorded image.

  At this time, the image display control means 32 controls the display method of the captured image based on the attitude determination signal 36 (1) of the imaging device 1 recorded in the captured image to be displayed. That is, since this photographed image is recorded with a 90 ° posture, as shown in FIG. 12 (b), it is automatically rotated and displayed from the state shown in FIG. 12 (a).

  That is, since the upper side of the subject is displayed on the upper side in the normal use state of the image pickup apparatus 1, there is no need to do wasteful operations such as rotating the main body of the image pickup apparatus 90 by 90 degrees as in the prior art.

  As described above, according to the fourth embodiment, when a captured image is displayed, the display method is controlled based on the attitude determination signal recorded in the captured image, so that the image capturing apparatus used by the photographer is used. The photographic image can be displayed in a normal use state of the imaging device without being influenced by the posture and without needless operations such as rotating the imaging device according to the photographic image.

  Next, a fifth embodiment of the present invention will be described with reference to FIGS. FIG. 13 is a diagram illustrating a display unit of an imaging apparatus according to the fifth embodiment, and FIG. 14 is a diagram illustrating thumbnail display. In addition, what was demonstrated so far attaches | subjects the same code | symbol and the description is abbreviate | omitted.

  In the hardware configuration diagram shown in FIG. 11, the captured image once recorded in the frame memory 9 is controlled to be written to the image recording means 11 such as an internal memory or a recording medium in accordance with a command from the image recording control means 10. . At the time of recording, a reduced image (thumbnail image) subjected to thinning processing is simultaneously created for each captured image and recorded together with the captured image.

  At the next playback time, the captured image recorded in the image recording unit 11 is transferred to the image display unit 33 such as a liquid crystal monitor mounted on the imaging apparatus 1 by the image display control unit 32 via the frame memory 45. Is displayed. At the time of display, nine images are displayed as thumbnails on one display screen.

  The operation of the imaging apparatus of the fifth embodiment configured as described above will be described below. When displaying a captured image on the liquid crystal monitor 33 mounted on the imaging apparatus 1, the display button 34 is pressed to display nine thumbnail images 1 to 9. As shown in FIG. 14 (a), of the nine thumbnail images, seven images Nos. 1 to 7 were taken in the horizontal posture shown in FIG. 24 (a). An attitude discrimination signal 36 (0) indicating that the attitude is 0 ° is added and recorded.

  Therefore, the thumbnail image is also displayed in a normal state based on the attitude determination signal 36 (0). On the other hand, the two images of Nos. 8 to 9 are taken in the vertical posture shown in FIG. 25A, and the posture discrimination signal 36 (indicating that the photographing posture is 90 ° is shown in the photographed image. 1) is added and recorded. Therefore, the thumbnail image is also displayed by being rotated by 90 ° from the normal state based on the attitude determination signal 36 (1).

  Further, when thumbnail images are displayed side by side in the order of shooting times of the shot images, for example, the vertical posture shot images and the horizontal posture shot images are mixed, which is very difficult to see. Therefore, in the present embodiment, images taken in the same posture are displayed as thumbnails together so that Nos. 1 to 7 are horizontal posture shot images and Nos. 8 to 9 are vertical posture shot images.

  Furthermore, since the storage folder for the horizontal posture shot image and the vertical posture shot image is distinguished by using the image file management method described in the third embodiment, the horizontal posture shot image and the vertical posture shot image are distinguished. Even if the shooting times are different, it can be displayed instantaneously. Finally, when an arbitrary thumbnail image is selected by the arrow key 53, the original photographed image is displayed. Further, by pressing the display switching button 54, as shown in FIG. 14B, it is also possible to switch to the thumbnail display in the order of the shooting time as usual, in which the horizontal posture shot image and the vertical posture shot image are mixed.

  As described above, according to the fifth embodiment, it is possible to display the horizontal posture captured image and the thumbnail image of the vertical posture captured image in the original posture of the subject. Conventionally, thumbnails were displayed in order of shooting time, so both horizontal and vertical posture images were mixed and very difficult to see, but the horizontal and vertical posture images were displayed together. Thus, it becomes very easy to see and selection of a desired photographed image becomes easy.

The liquid crystal panels 69 and 70 are respectively irradiated. In other words, the S-polarized component light divided by the polarization beam splitter 61 is reflected by the total reflection mirror 66, and only the red wavelength light is reflected by the dichroic mirror 64, and the rest is transmitted. The red wavelength light reflected by the dichroic mirror 64 is sequentially reflected by total reflection mirrors 67 and 68 and applied to the red liquid crystal display panel 68.

The light transmitted through the dichroic mirror 64 is reflected only by the blue wavelength light at the next dichroic mirror 65, and this reflected light is applied to the blue liquid crystal display panel 70. In this way, the red, green, and blue liquid crystal display panels 63, 69, and 70 irradiated with light of each wavelength display an image for each color, and a pair of transparent electrode substrates are provided between them.
