However, this technique has a problem that when the subject to be photographed is a moving subject, the motion of the subject is detected as a vector quantity instead of the motion of the photographing device.

Therefore, in recent years, in addition to the motion vector detecting means for detecting the motion vector, a physical sensor for physically detecting the amount of shaking of the photographing apparatus is provided, and the shaking detected by the physical sensor with respect to the magnitude of the detected value of the motion vector. When the amount is small, that is, when the detection value of the motion vector is unlikely to indicate a shake of the imaging device, the shake is corrected based on the detection value of the physical sensor instead of the detection value of the motion vector An imaging device has been proposed. Therefore, according to this photographing apparatus, it is possible to determine which of the movement of the photographing apparatus and the movement of the subject indicates the motion vector detection value.

Embodiments of the present invention will be described below with reference to the drawings. Hereinafter, a case where the present invention is applied to a portable digital video camera (hereinafter simply referred to as “video camera”) as one aspect of the photographing apparatus will be described.
FIG. 1 is a block diagram showing a configuration of a video camera 1 according to the present embodiment. As shown in FIG. 1, the video camera 1 includes a control unit 10, a photographing unit 20, an angular velocity detection unit 30, an operation unit 40, a removable medium 50, an I / F unit 51, and a video output terminal 52.

  The control unit 10 functions as a control unit that controls each unit of the video camera 1, and can be rewritten to store a CPU 11 that executes various programs and performs arithmetic processing, a control program 100 that the CPU 11 executes, and various data. A flash ROM (hereinafter simply referred to as “ROM”) 12 and a RAM 13 functioning as a work area for temporarily storing calculation results of the CPU 11 and various data. The control program 100 includes a shake correction program 100A, and the control unit 10 executes the shake correction program 100A when displaying a moving image, thereby realizing a moving image display without a shake.

  The control program 100 can be recorded and distributed on a computer-readable recording medium 60 such as a CD-ROM or DVD-ROM. Further, the personal computer and the video camera 1 are communicably connected by a cable or the like, and the control program 100 of the recording medium 60 read by the personal computer is output to the video camera 1 so that the control program 100 is stored in the flash ROM 12. It is also possible to make it.

  The photographing unit 20 photographs a subject 80 (see FIG. 2) as a moving image, and includes a camera control circuit 21, a photographing camera 22, a photographing unit RAM 23, and a display panel 24. The camera control circuit 21 controls each unit of the photographing unit 20 under the control of the control unit 10. The photographing camera 22 sequentially outputs frame data (hereinafter simply referred to as “frame”) obtained by imaging the subject 80 to the camera control circuit 21 at a predetermined sampling rate. Image sensor in which elements are arranged in a matrix or honeycomb, an optical lens system having a plurality of optical lenses, and a lens driving device for driving the optical lens system to realize zoom / focus, diaphragm, etc. An analog signal image acquired by the image sensor is converted into a digital signal, and an A / D conversion circuit that outputs image data is provided.

  The photographing unit RAM 23 functions as a buffer for temporarily storing frames. The display panel 24 displays various types of information such as captured moving images and setting screens, and is configured by a flat display panel such as a liquid crystal display panel or an organic EL panel, for example. The removable medium 50 stores moving image data at the time of shooting, and includes, for example, a video tape, a recordable optical disk, and a removable hard disk.

  The frame output from the photographing camera 22 is subjected to predetermined image processing by the camera control circuit 21 and then temporarily stored in the photographing unit RAM 23, and can be sequentially stored as moving image data on the removable medium 50 via the control unit 10. The The frame stored in the imaging unit RAM 23 is used when displaying a captured moving image on the display panel 24 in real time, and the moving image data stored in the removable medium 50 is used when displaying (reproducing) the captured moving image after shooting. It is done.

  The angular velocity detection unit 30 functions as a shake amount detection means for detecting the shake amount at the time of shooting. Specifically, as shown in FIG. 2, the angular velocity detection unit 30 moves in the horizontal direction of the frame 70 (hereinafter, defined as Y axis) and in the height direction (hereinafter, defined as X axis). The angular velocities ωx (rad / sec) and ωy (rad / sec) associated with the movement are individually detected. As shown in FIG. 1, two X-axis gyro sensor 31 and Y-axis gyro sensor 32 are used. Each of the gyro sensors 31 and 32 outputs an angular velocity detection signal having a voltage value corresponding to the angular velocities ωx and ωy to the control unit 10. The control unit 10 captures the angular velocity detection signals of the respective gyro sensors 31 and 32 in synchronization with the frame rate of the frame 70 at the time of moving image shooting, and associates them with the frame 70 or adds them to the frame 70 to the removable medium 50. Store.

Note that due to factors such as individual differences between the gyro sensors 31 and 32, the voltage value of the angular velocity detection signal may be different for each gyro sensor 31 and 32 even when the angular velocities ωx and ωy are zero. Therefore, in the present embodiment, the angular velocity detection signals of the respective gyro sensors 31 and 32 are sampled and the average value is set as the zero point voltage value after the main body is turned on and before the photographing is started. is doing. At this time, when a plurality of zero point voltage values are obtained over a certain period of time, and the difference between the zero point voltage values and the average value of these zero point voltage values is equal to or less than a predetermined value, a certain percentage (eg, 99%) or more is obtained. In addition, the average value of the zero point voltage values is set as the actual zero point voltage value, which makes it possible to set the zero point voltage value when the main body is stopped.
In the following description, the angular velocities ωx and ωy of the X axis and the Y axis are expressed as “angular velocities ω” when it is not necessary to distinguish them.

  Returning to FIG. 1 again, the operation unit 40 has a plurality of operation elements operated by the user, and has operation keys for inputting various instructions such as a power button and photographing start / end, for example. The I / F unit 51 is an interface for connecting the video camera 1 to a personal computer through a cable or the like so as to be able to communicate with the personal computer. The video output terminal 52 is a terminal for outputting a video signal of a moving image to an external display device such as a television or a projector. In addition to the above-described components, the video camera 1 includes an audio circuit for capturing and recording / reproducing an audio signal, an audio output terminal for outputting the audio signal to an external speaker, an external amplifier, and the like. Configured.

  Here, in the video camera 1 according to the present embodiment, the moving image being shot is displayed in live view (in real time) on the display panel 24, or the moving image data stored in the removable medium 50 is displayed on the display panel 24 or externally. When displaying on the display, the blur amount G and the angular velocities ωx and ωy of the edge (contour) 70A (see FIG. 2) of the image for each frame 70 are detected, and based on these blur amounts G and angular velocities ωx and ωy. Identify whether the blurring factor is camera shake, movement of the subject 80 or camera work, and if the blurring factor is camera shake or movement of the subject 80, correct the camera shake during shooting. It is said.

  More specifically, when the video camera 1 and the subject 80 move relative to each other, the larger (faster) the movement, the more the edge 70A of the image in the frame 70 is blurred. Therefore, the video camera 1 is detected by detecting the blur amount of the edge 70A. It is possible to detect whether a relatively large relative movement has occurred between the subject 80 and the subject 80. On the other hand, since the motion of the video camera 1 can be detected by the angular velocity detection unit 30, when a relatively large relative movement between the video camera 1 and the subject 80 is detected, it is detected by the angular velocity detection unit 30. Based on the angular velocity ω, it can be specified which of the video camera 1 and the subject 80 is moving.

  A specific example will be described with reference to FIG. 3 showing one aspect of the relationship between the movement of the video camera 1, the blur amount G, and the angular velocity ω. Section (II) [time t1 to time t1 in which a relatively large blur amount G is detected. When t2] and section (III) [time t3 to t4] are compared, the amount of blur G is substantially the same in both sections (II) and (III), but the angular velocity ω is greater in section (III). Is big. Therefore, the cause of the increase in the blur amount G in the section (II) can be specified as a large movement of the subject 80, and the cause of the increase in the blur amount G in the section (III) is a large movement of the video camera 1. Can be specified.

  Further, the movement of the video camera 1 includes camera shake and camera work, and it can be specified by the magnitude of the angular velocity ω which factor caused the movement of the video camera 1. That is, since the moving amount of the video camera 1 is larger for camera work than for camera shake, a relatively large angular velocity ω is detected during camera work. For example, when the angular velocities ω in the sections (I) to (III) in FIG. 3 are compared, the angular velocities ω are relatively small in the section (I) [time t0 to t1] and the section (II). It can be specified that the video camera 1 is moving, and since the angular velocity ω is relatively large in the section (III), it can be specified that the video camera 1 is moving greatly due to camera work.

  From the above, when the blur amount G and the angular velocity ω are both large, the blur factor can be specified as camera work, and when the blur amount G is large but the angular velocity ω is small, the blur factor is large in the subject 80. Can be identified as moving. When the blur amount G is small, it can be specified that the blurring factor is camera shake. Then, when it is specified that the blurring factor is camera shake and when it is specified that the subject 80 is moving, the camera shake at that time is contrary to the intention of the photographer. Therefore, camera shake correction processing for correcting camera shake is executed.

Note that the magnitude of the blur amount G and the angular velocity ω can be discriminated by providing a threshold value. That is, the blur amount G and the angular velocity ω at the time of normal camera shake are sampled in advance by experiments or the like, and based on this sampling value, the blur threshold Gth of the blur amount G that can be regarded as the cause of blurring, and the video camera 1 An angular velocity threshold value ωth of an angular velocity ω that can be regarded as a camera shake is set in advance, and the blur threshold value Gth and the angular velocity threshold value ωth are compared with the blur amount G and the angular velocity ω, respectively. What is necessary is just to discriminate.
The blur amount G of the edge 70A is a method for quantifying the blur of the image based on the power spectrum of the image in the frequency domain, or a weighted appearance histogram of all non-zero DCT (discrete cosine transform) coefficients included in the digital image data. It is possible to obtain the image using a method for quantifying the blur of the image based on the above.

  Here, camera shake at the time of photographing can be detected based on the angular velocity ω, but in the present embodiment, it is detected based on the blur amount G. As described above, since the camera shake is detected based on the blur amount G, even if the detected value of the angular velocity ω varies due to individual differences of the gyro sensors 31 and 32 of the angular velocity detection unit 30, a constant amount of camera shake is always generated. Camera shake can be detected as a reference.

Next, processing during shooting as the operation of the video camera 1 will be described with reference to FIG.
FIG. 4 is a flowchart showing the operation of the video camera 1 during shooting. As shown in this figure, the control unit 10 monitors the operation of the operation unit 40 and, when detecting an input of a shooting start instruction (step S1: Yes), acquires the frame 70 of the shot image from the shooting unit 20. (Step S2) In order to determine whether or not it is necessary to perform the camera shake correction process on the frame 70, the following process is executed.

That is, the control unit 10 acquires the angular velocities ωx and ωy when the frame 70 is captured based on the angular velocity detection signal output from the angular velocity detection unit 30 (step S3), and the blur amount G of the frame 70 Is calculated (step S4).
Next, the control unit 10 determines whether or not the blur amount G is equal to or less than the blur threshold value Gth (step S5). If the blur amount G is equal to or less than the blur threshold value Gth (step S5: Yes), the cause of the blur is Since the camera shake is identified, a process for correcting the camera shake of the frame 70 is executed.

  On the other hand, when the blur amount G is equal to or greater than the blur threshold Gth (step S5: No), it is indicated that the cause of the blur is a large relative movement between the video camera 1 and the subject 80. Therefore, the control unit 10 determines whether the angular velocities ωx and ωy are both equal to or lower than the angular velocity threshold ωth in order to specify whether the subject of movement is the video camera 1 or the subject 80 (step S6). . As a result of this determination, if any one of the angular velocities ωx and ωy is larger than the angular velocity threshold ωth (step S6: No), it is specified that the video camera 1 is moving greatly due to the camera work of the photographer. Therefore, the control unit 10 outputs the frame 70 as it is to the display panel 24 and the removable medium 50 without executing processing for correcting camera shake (step S7).

When the angular velocities ωx and ωy are equal to or lower than the angular velocity threshold ωth (step S6: Yes), the subject 80 is identified as having moved greatly, so the control unit 10 corrects camera shake of the frame 70. Execute the process.
That is, the control unit 10 first calculates the shake amount Q based on the angular velocities ωx and ωy at the time of photographing acquired in step S3 (step S8). Specifically, the control unit 10 calculates the angle by time-integrating the angular velocities ωx and ωy according to the sampling time of the angular velocities, and calculates the shake amount Q (Pixel) based on the angles and the focal length L. The image of the frame 70 is corrected based on the shake amount Q, and the corrected frame 70 is output (step S7).

Specifically, when camera shake of a shake amount Q occurs during shooting, as shown in FIG. 5A, the shooting range R1 to be shot is moved by the shooting range R0 shake amount Q intended by the photographer. End up. Therefore, the frame 70 is corrected by moving the shooting range R1 to the shooting range R0 so as to cancel the blur amount Q at the time of shooting, and cutting out the image of the shooting range R0 to generate the frame 70.
That is, at the time of shooting, as shown in FIG. 5B, the video camera 1 shoots a predetermined size with respect to the shot image 200 shot by the shooting unit 20 with the center of the shot image as the center position. The frame 70 is generated by trimming the range R0. Then, when camera shake occurs at the time of shooting, and the shooting range becomes the shooting range R1, as shown in FIG. 5C, the video camera 1 compensates for the movement of the shooting range due to camera shake. The shooting range is moved by the amount of shake Q in the direction opposite to the direction so that the shooting range becomes the shooting range R0. Then, as shown in FIG. 4D, the video camera 1 generates a frame 70 by trimming an image in the shooting range R0 in the shot image 200, so that an image when no camera shake occurs is the frame 70. Can be output.

  After the control unit 10 of the video camera 1 outputs the frame 70 (step S7), the control unit 10 determines whether or not a shooting end instruction is input from the operation unit 40 (step S10). Is not input (step S10: No), the processing of step S2 to step S9 is repeatedly executed, and when a photographing end instruction is input (step S10: Yes), this processing is ended.

  As described above, according to the present embodiment, when the blur amount G is larger than the blur threshold Gth, frame blur is corrected according to the magnitude of the angular velocity ω, that is, the blur amount Q. Since whether or not to correct the camera shake of the frame image larger than the camera shake due to the camera work of the photographer and whether or not the camera shake has occurred during the shooting can be switched. It will be. Thereby, it is possible to identify the camera work and prevent the camera work from being corrected.

  Further, according to the present embodiment, although it is possible to detect camera shake at the time of shooting based on the angular velocity ω, it is detected based on the amount of blur G. Therefore, the gyro sensor 31 of the angular velocity detecting unit 30, Even if the detected value of the angular velocity ω varies due to the individual difference of 32 or the like, it is always possible to detect camera shake based on a certain amount of camera shake.

The above-described embodiment is merely an aspect of the present invention, and can be arbitrarily modified and applied within the scope of the present invention.
For example, as an index of the blur amount G in the above-described embodiment, for example, the total amount (for example, the number of pixels) of the edge 70A included in the image of the frame 70 can be used. That is, as the blur of the image increases, the total amount of the edge 70A decreases. Therefore, the blur amount G may be evaluated according to the degree of the decrease.
Further, for example, in the above-described embodiment, the configuration in which the shake amount is detected based on the angular velocity is illustrated, but the configuration is not limited thereto, and a configuration in which the shake amount is detected using an acceleration sensor may be employed. Further, for example, a configuration may be adopted in which the amount of blur is detected by image processing such as calculating the amount of movement of feature points between frames and calculating the amount of blur of the frame based on the amount of movement.
Further, for example, in the above-described embodiment, when the blur amount G is equal to or greater than the blur threshold Gth, that is, when a relatively large relative movement between the video camera 1 and the subject 80 is detected, the process proceeds to step S6 in FIG. As shown, the magnitude of the angular velocity ω and the angular velocity threshold value ωth are compared to identify which one of the video camera 1 and the subject 80 is moving. However, the present invention is not limited to this, and in step S6, based on the angular velocity ω. The camera shake amount Q may be calculated, and based on the amount of the camera shake amount Q, it may be identified which of the video camera 1 and the subject 80 is moving.

Further, in the above-described embodiment, the case where the present invention is applied to the portable digital video camera 1 which is one aspect of the photographing apparatus is illustrated. However, for example, a cellular phone, a digital camera, a PDA, a notebook personal computer having a moving image photographing function. The present invention can also be applied to the above.
The present invention can also be implemented as a moving image display apparatus that executes only the moving image display function realized by the above-described portable digital video camera 1 executing the control program 100 including the blur correction program 100A.
Furthermore, the present invention can also be applied to a shake correction apparatus that sequentially acquires frames constituting a moving image and corrects camera shake. Specifically, the blur correction apparatus is configured to acquire the blur amount G and the blur amount Q (or angular velocity ω) at the time of shooting together with the frame 70, and the blur amount G is smaller than the blur threshold Gth. When the amount of blur is small, the blur generated in the frame 70 is corrected. When the amount of blur G is larger than the blur threshold Gth, whether the blur of the frame 70 is to be corrected or not is determined. It can be implemented by configuring to switch according to the size.
