Description

  The present invention relates to an image pickup method and an image pickup apparatus, and more particularly to an image pickup method and an image pickup apparatus having blur correction.

  2. Description of the Related Art Conventionally, a camera with a camera shake correction function that corrects a blur generated during camera shooting has been widespread. However, since an additional correction mechanism (for example, a drive control system such as a correction lens) is required, there is an aspect that is incompatible with the demand for downsizing the camera. In particular, beginners who often experience camera shake often use a compact camera. Therefore, an apparatus for preventing image blurring without using a correction lens has been proposed. This is to suppress the occurrence of image blur by starting a shutter opening operation (release) when camera shake is at an allowable size or within an allowable size (for example, Patent Document 1).

As a device equipped with a correction mechanism, camera shake detection is performed, the drive amount of the correction optical member is calculated based on the detection result, and the correction optical member is driven based on the calculation result to correct the camera shake. The device is known. In addition, not only simple linear motion but also rotational motion is generally added to camera shake, so even if there is a component of rotational motion, it is effectively corrected appropriately so that the photographed image does not blur. A camera has also been proposed (see, for example, Patent Document 2).
Japanese Patent No. 2603871 Japanese Patent Laid-Open No. 05-173219

  However, the technology that suppresses the occurrence of image blur by starting the shutter opening operation (release) described above, puts effort into the hand so as not to shake the camera until when it is within an allowable size. There is a problem that it is difficult to use because I do not know what to do. In addition, when the photographer does not know when the release was made and the subject changed at the moment of shooting, it is difficult to notice the failed shooting that the shooting scene was not intended later. Difficulties arise. In addition, due to recent technological progress, the driving device has been downsized, and an image blur correction device can be mounted even in a compact camera.

  However, even with a device equipped with the above correction mechanism, if the release button is pushed in an unstable manner, the camera shakes greatly at the moment of release, and if the camera shakes more than the correctable amount, correction may not be possible. is there.

The correction amount of the blur correction unit 11 is calculated, and the image blur is corrected by driving the image blur correction unit 11 based on the correction amount.

  In FIG. 1, a lens 1 is a lens for forming a subject image on an image sensor 3, and a diaphragm 2 is for limiting the amount of light of the subject image. The imaging device 3 is a circuit that converts a subject image that passes through the lens 1 and the diaphragm 2 into an electrical signal and outputs it as an image signal. Specifically, a CCD (charge coupled device) can be used. The A / D converter 4 is a circuit that converts an image signal input from the image sensor 3 into a digital signal and outputs the image signal as image data suitable for image processing.

Specifically, an LCD or the like can be used. In addition, power consumption can be reduced by turning off the backlight.

  The operation command unit 8 is a user interface that commands operation of the imaging apparatus such as recording start / stop / deletion in the image recording unit 6, image reproduction on the image display unit 7, and release. The shooting mode selection unit 9 is a user interface that selects either a still image shooting mode for shooting a still image or a moving image shooting mode for shooting a moving image. The camera shake detection unit 10 is a detection unit that detects camera shake of the imaging apparatus main body.

  Here, a specific configuration of the camera shake detection unit 10 according to the present embodiment will be described. FIG. 2 is a block diagram showing a specific configuration of the camera shake detection unit 10 shown in FIG. The camera shake detection unit 10 according to the present embodiment includes a gyro 21, a low-pass filter 22, a high-pass filter 23, and an amplifier 24. In FIG. 2, a gyro 21 is a detection unit that detects a rotational angular velocity in a certain axial direction due to camera shake. In the present embodiment, the one that detects the rotational angular velocity in a certain axial direction is shown. However, the one that detects the physical quantity related to the rotational angular displacement around two axes that are parallel to the imaging surface and substantially perpendicular to each other, It may be one that detects a physical quantity related to the rotational angular displacement of the other, or one that has detection of at least one of the other two axes.

  The low-pass filter 22 and the high-pass filter 23 are filters that allow only rotation angular velocities in a predetermined frequency band to pass and remove noise and offset mixing. The amplifier 24 rotates after passing through the low-pass filter 22 and the high-pass filter 23. This circuit amplifies the angular velocity signal. In the present embodiment, since the high-pass filter is not provided in the still image mode correction amount calculation unit 12 shown in FIG. 1, the cut-off frequencies of the low-pass filter 22 and the high-pass filter 23 are corrected in the still image shooting mode. It is set to a value suitable for quantity calculation (a value that allows a wide frequency band to pass).

  In FIG. 1, the image blur correction unit 11 corrects image blur based on the still image mode correction amount or the moving image mode correction amount calculated by the still image mode correction amount calculation unit 12 or the moving image mode correction amount calculation unit 13. Part.

  In the present embodiment, the image blur correction unit 11 that translates the image pickup device 3 by a distance corresponding to the correction amount is shown, but in addition to this, a device that shifts the correction lens or a variable apex angle prism may be used. Further, the image blur correction unit 11 may be configured differently between the still image shooting mode and the moving image shooting mode, or an electronic image blur correction method may be used. The still image mode correction amount calculation unit 12 calculates the correction amount of the image blur correction unit 11 based on the camera shake detected by the camera shake detection unit 10 when the still image shooting mode is selected by the shooting mode selection unit 9. Is a circuit for calculating.

Here, a specific configuration of the still image mode correction amount calculation unit 12 according to the present embodiment will be described. FIG. 3 is a block diagram showing a specific configuration of the still image mode correction amount calculation unit 12 shown in FIG. As illustrated in FIG. 3, the still image mode correction amount calculation unit 12 according to the present embodiment includes an integrator 31 and a multiplier 32. The integrator 31 is a circuit that integrates the rotation angular velocity detected by the camera shake detection unit 10 from the start time of camera shake correction and calculates the rotation angle displacement of the imaging apparatus body from the start time of camera shake correction. Specifically, it is calculated based on the following formula.
i (t) ← i (t) × T + i (t−1)
(Where i (t): rotational angular velocity at time t, T: sampling interval)

The multiplier 32 is a circuit that calculates the still image mode correction amount by multiplying the rotational angular displacement input from the integrator 31 by a predetermined coefficient. Specifically, it is calculated based on the following formula.
o (t) = A × i (t)
(Where o (t): still image mode correction amount, A: predetermined coefficient)
In the present embodiment, as shown in FIG. 2, the cutoff frequencies of the low-pass filter 22 and the high-pass filter 23 in the camera shake detection unit 10 are set to values suitable for the correction amount calculation in the still image shooting mode. The still image mode correction amount calculation unit 12 does not include a high-pass filter.

  In FIG. 1, the moving image mode correction amount calculation unit 13 is based on the camera shake detected by the camera shake detection unit 10 when the moving image shooting mode is selected by the shooting mode selection unit 9. It is a circuit for calculating a correction amount.

  Here, a specific configuration of the moving image mode correction amount calculation unit 13 according to the present embodiment will be described. FIG. 4 is a block diagram showing a specific configuration of the moving image mode correction amount calculation unit 13 shown in FIG. As shown in FIG. 4, the moving image mode correction amount calculation unit 13 according to this embodiment includes a high-pass filter 41, an integrator 42, and a multiplier 43. The high-pass filter 41 is a filter that passes only the rotation angular velocity in a predetermined high frequency band among the rotation angular velocities detected by the camera shake detection unit 10.

The cut-off frequency of the high-pass filter 41 is a value suitable for calculating the correction amount in the moving image shooting mode on the higher frequency side than the cut-off frequency of the high-pass filter 23 shown in FIG. Value that is not allowed to pass). Specifically, the rotational angular velocity that passes through the high-pass filter 41 is calculated based on the following equation.
j (t) = B × {i (0),..., i (N−2)} t
(Where j (t): rotational angular velocity passing through the high-pass filter 41 at time t, B: row vector forming the high-pass filter 41, i (0) to i (N-2): detected by the camera shake detection unit 10 Time t = 0 to t = rotational angular velocity at N−2)

The integrator 42 is a circuit that integrates the rotational angular velocity that has passed through the high-pass filter 41 from the start time of camera shake correction, and calculates the rotational angle displacement of the imaging apparatus body from the start time of camera shake correction. Specifically, it is calculated based on the following formula.
j (t) ← j (t) × T + j (t−1)
(Where j (t): rotational angular velocity at time t that has passed through the high-pass filter 41, T: sampling interval)

The multiplier 43 is a circuit that calculates the moving image mode correction amount by multiplying the rotational angular displacement input from the integrator 42 by a predetermined coefficient. Specifically, it is calculated based on the following formula.
o (t) = C × i (t)
(However, o (t): moving image mode correction amount, C: predetermined coefficient)

  In the present embodiment, the still image mode correction amount calculation unit 12 and the moving image mode correction amount calculation unit 13 calculate the correction amount of the image blur correction unit 11 based on the rotational angular velocity around a certain axis. Alternatively, the correction amount may be calculated by detecting rotational angular velocities around other axes. As described above, when the calculation is performed using the rotational angular velocities of two or more axes, it is desirable to perform the calculation in parallel, but the calculation may be performed sequentially.

  FIG. 7 is a schematic diagram illustrating a correction mechanism of the image blur correction unit 11. A left-right actuator 51 is fixed to the support plate 50, and a drive shaft 52 of the left-right direction actuator 51 is coupled to the image sensor support plate 53. When the left-right direction actuator 51 is driven, the image sensor support plate 53 can be moved in the left-right direction. The vertical actuator 54 is fixed to the imaging apparatus main body, and the drive shaft 55 of the vertical actuator 54 is coupled to the support plate 50. When the vertical actuator 54 is driven, the support plate 50 can be moved in the vertical direction. Thereby, the image sensor 56 can be moved in accordance with the correction amount o (t) described above to correct the image blur.

  In addition, the vertical and horizontal actuators and the image blur correction mechanism including these cannot handle large blur corrections such as 10 mm or more when the size is set in a compact camera. Even if the movable range can be increased, there is a limit to moving a large distance instantaneously.

  In FIG. 1, the control unit 14 is a processing unit that controls each unit of the imaging apparatus. By the operation of the button in the operation command unit 8, the still image mode and the moving image mode of the shooting mode selection unit 9 are set. When the still image shooting mode is selected by the shooting mode selection unit 9, when the release button in the operation command unit 8 is pressed, the camera shake stabilization standby is first performed. That is, the camera shake detection unit 10 detects a rotation angular velocity signal, and the still image mode correction amount calculation unit 12 calculates an image blur correction amount. From the detection of the rotational angular velocity, the calculation of the image blur correction amount is repeated, and the process waits until the absolute value of the detected image blur amount becomes smaller than A. Specifically, since the average value of the amount of vertical movement of the camera when the release button is pressed during shooting is a value of 2 to 3 mm, for example, the above-described A is used to correct image blur when vertical movement of 2 mm occurs during shooting. And wait until it becomes smaller than this value.

  When the absolute value of the image blur correction amount becomes smaller than A, image blur correction processing is performed next. In the image blur correction process, an image blur correction start signal is sent to the camera shake detection unit 10 to execute the image blur correction process in the still image shooting mode. Thereafter, an image blur correction end signal is sent to the image blur correction unit 11 to complete the blur correction process, and then the image sensor 3 is exposed to perform the image pickup process.

  In the present embodiment, a shutter sound is emitted from the speaker 16 at the timing of performing the imaging process (or a simple buzzer sound may be used), and the imaging start icon 57 is displayed on the image display unit 7 as shown in FIG. Display time. FIG. 8 is a diagram illustrating an example of icons displayed on the image display unit 8.

  As another embodiment according to the present invention, it may be considered that the timer 15 counts the time after the release button is pressed. When the timer 15 has elapsed for a predetermined time B, for example, 500 msec or longer, image stabilization processing and imaging processing are performed without performing camera shake stabilization standby. Furthermore, the image pickup apparatus can be set to a setting state of “without camera shake stabilization standby” so as not to perform camera shake stabilization standby by operating a button in the operation command unit 8. When [Do not wait for camera shake stabilization] is set, image stabilization processing and imaging processing are performed immediately without performing camera shake stabilization standby after the release.

  In the present embodiment, the shutter 16 emits a longer shutter sound (may be a simple buzzer sound) at the timing of performing the imaging process, and the imaging start icon 58 is displayed on the image display unit 7 as shown in FIG. 8B. Is displayed for a short time.

  According to each of the above embodiments, when a transition is made to the imaging stage, a predetermined sound is played or a predetermined display is performed, so that the user can grasp the imaging timing, and does not shake the hand until when. It becomes clear what should be put in, and it is easy to notice failure shooting, and usability is improved.

  In addition, the control unit 14 turns on the power of the electronic circuits of the camera shake detection unit 10 and the image blur correction unit 11 during the image blur correction process according to the power source CNT signal. Can be suppressed. Further, when the power of the imaging apparatus is turned on and the setting mode of the shooting mode selection unit 9 is the still image shooting mode or the moving image shooting mode, the image obtained from the image sensor 3 is always displayed on the image display unit 7. Monitoring starts. In the monitoring, image blur correction in the moving image mode is always performed even in the still image mode. In addition, when the movie shooting mode is selected, when the release button (or recording start button) is pressed, image blur correction processing in the movie shooting mode is always performed, and then the release button (or recording stop button again). ) Is pressed, the image blur correction in the moving image shooting mode is terminated.

  Next, the control when the release button is pressed in the still image mode according to the embodiment of the present invention will be described with reference to the flowchart of FIG. First, it waits until the release 1 is pushed (step S1). Release 1 is an operation in which the release button is pressed to lock the focus. If it is pressed (step S1 / Yes), release 1 processing for locking the focus is performed (step S2). Next, it waits until the release 2 is pushed (step S3). Release 2 is for actually shifting to shooting. When release 2 is pressed (step S3 / Yes), it is checked whether or not [do not wait for camera shake stabilization] is set (step S4).

  If it is not set to [No camera shake stabilization standby] (step S4 / No), a time count is started to perform camera shake stabilization standby (step S5). The circuit power supply is turned on (step S6), the angular velocity is detected (step S7), and the rotational angular displacement is calculated (step S8). The correction amount is calculated (step S9), and the circuit power supply is turned off (step S10). It is checked whether or not the rotational angular displacement calculated in step S8 is within a predetermined range (step S11). If it is not within the predetermined range (step S11 / No), it is checked whether or not a predetermined time has elapsed after the timer starts counting time (step S12). If the predetermined time has not elapsed (step S12 / No), the process returns to step S11.

  If “Do not wait for camera shake stabilization” is set in Step S4 (Step S4 / Yes), the camera shake stabilization process immediately after release (Steps S5 to S12) is not performed. (Step S14) and an imaging process are performed (Step S16). Thereby, it is possible to set permission / prohibition of the shake detection process. When the prohibition setting is made, in order to perform the imaging process without performing the shake detection process (steps S5 to S11) after the release, You can shoot even when there is constant vibration, such as in a vehicle.

  Further, when the camera shake stabilization standby flow is advanced and the image blur correction amount is within the predetermined range (step S11 / Yes) or not within the predetermined range (step S11 / No), the predetermined time has elapsed. Also in (Step S12 / Yes), when the shift to the imaging process is not canceled (No in Step S13), the image blur correction process (Step S14) is performed. Such correction processing will be described in detail with reference to a flowchart described later.

  Note that if the amount of rotation displacement does not fall within the predetermined range even after a predetermined time has elapsed and the imaging process is canceled (step S13 / Yes), the process returns to step S1. As a result, even if there is constant vibration such as strong winds or in a vehicle, and the blur does not stop, the imaging process is canceled after a predetermined time from the start of imaging, and the process proceeds to before imaging (step 1). Therefore, it will not be in a stalled state until the blur is settled.

  After the image blur correction process (step S14), the imaging process is started and a shutter sound is sounded, and an imaging start icon 57 (see FIG. 8A) is displayed on the image display unit 7 for a short time. Notification is made (step S15). After the imaging process (step S16) ends, the process returns to step S1.

  According to the above-described embodiment, even if the image blur correction amount is not within the predetermined range, after the predetermined time has elapsed, the process proceeds to the imaging process (steps S11 / No to S15 in FIG. 5). Shooting is possible even when there is constant vibration and blurring does not stop.

  In addition, when each displacement amount does not fall within a predetermined range even after a predetermined time has passed and the process shifts to an imaging process (FIG. 5, Step S12 / Yes, Step S13 / No), Step S15 in FIG. Can also perform different operations. For example, a different sound or display may be considered, and a longer shutter sound may be generated and the imaging start icon 58 may be displayed on the image display unit 7 (see FIG. 8B).

  According to the above-described embodiment, whether the process has shifted to the shooting process after reaching a predetermined time (step S11 / No to step S15), or whether the blur is within an allowable size and the process has shifted to the shooting step (step S11 / Yes to step S15). ), So that it can be distinguished by predetermined sound and display, it is easy to re-shoot even if the shooting purpose must be an image that cannot tolerate image blur at all. You can notice.

  FIG. 6 is a flowchart showing the image blur correction processing operation called in S14 of FIG. For image blur correction, the circuit power supply is turned on (step S20), the angular velocity is detected (step S21), and the rotational angular displacement is calculated (step S22). Based on these, the correction amount is calculated (step S23), the correction amount is output (step S24), and the circuit power supply is turned off (step S25). Examples of processing different between the still image mode and the moving image mode include a processing of cutting a low frequency range of data detected by detecting the angular velocity in the moving image mode.

  The present invention can also be applied to a digital camera, a digital video camera, and a mobile phone with a digital camera having a still image shooting function.

  Although the present invention has been specifically described above based on the preferred embodiments, it is needless to say that the present invention is not limited to the above-described ones and can be variously modified without departing from the gist thereof.
