Description

  The present invention relates to an imaging apparatus capable of imaging with less blur, a control method thereof, a control program, and a recording medium.

Conventionally, a camera having a blur detection function is known. For this type of camera, the amount of camera shake detected after the shutter button is operated is compared with the camera shake tolerance value. If the camera shake amount is greater than the camera shake tolerance value, the camera shake tolerance value is changed from the normal shooting mode to a lower value. There is a camera that takes a picture when the camera shifts to a camera shake reduction mode and the camera shake amount falls below a camera shake tolerance (for example, Patent Document 1).
In addition, some cameras of this type perform shooting at a timing delayed by a predetermined time from the timing at which the maximum value of the shake amount waveform after the shutter button operation is detected (for example, Patent Document 2).
Japanese Patent Laid-Open No. 8-320511 JP-A-5-107622

However, the one described in Patent Document 1 is a case where the amount of shake converges later because the image is taken on condition that the amount of shake is less than a predetermined shake tolerance regardless of whether or not the amount of shake converges. However, there is a case where shooting is performed before convergence, and an image with less blur cannot be efficiently shot. In addition, in the case where blurring does not converge but is steadily occurring, shooting is not performed until the shift to the blur reduction mode is performed, so that there is a problem that the time lag until shooting is increased.
On the other hand, since the shooting is performed based on the timing at which the maximum value of the blur amount waveform is detected regardless of whether or not the blur amount converges, the image is also taken at the timing when the blur has converged. Can not do.

  The present invention has been made in view of the above-described circumstances, and is a photographing apparatus that can easily identify a camera shake tendency of a photographer and photograph a reduced shake, a control method thereof, a control program, and a recording medium. Is to provide.

In order to solve the above-described problems, the present invention provides an imaging device that performs imaging based on an operation of a shooting instruction operator, a blur detection unit that detects a blur of the imaging unit, and a blur detection unit. At least one shake before and after the operation of the operation element is detected, and it is determined whether or not the shake has a shake having a predetermined amplitude or more within a predetermined frequency range. Based on the determination result It is characterized by comprising an imaging control means for specifying a camera shake tendency of a photographer and executing an imaging process according to the specified camera shake tendency.
According to the present invention, at least one shake before and after the operation of the operation instruction for the photographing instruction is detected, and whether or not the shake has a shake with a predetermined amplitude or more within a predetermined frequency range. Since the camera shake tendency of the photographer is determined based on the determination result and the photographing process is executed according to the identified camera shake tendency, the camera shake of the photographer is performed without performing a prediction calculation or the like for predicting the camera shake tendency. The tendency can be identified easily and quickly, and an image with reduced blur can be taken.

  In the above invention, it is preferable that the photographing control unit determines whether or not a shake having a predetermined amplitude or more is constantly present in the vicinity of 10 Hz. According to this configuration, it is possible to determine whether or not there is a steady shooting-specific blur, and in advance whether the camera shake tendency of the photographer belongs to a photographer or an unskilled photographer. Even if the photographer is a photographer who is a photographer, even if a blur similar to “blurring peculiar to an unskilled photographer” occurs rarely, the occurrence frequency is low. Can be avoided if it is erroneously determined to be an inexperienced person.

  In the above invention, when the shooting control unit specifies whether or not the camera shake tendency of the photographer is converged, and specifies that the camera shake tendency of the photographer is converged, after the operation of the operator When the amount of blurring reaches the amount of blurring before the operation of the operation element, it is preferable to perform photographing by the photographing unit. According to this configuration, it is possible to immediately shoot at the timing when the camera shake tendency converges, and it is possible to shoot an image with a small amount of blur under appropriate shooting conditions while suppressing a time lag.

  In the above invention, when the shooting control unit specifies whether or not the camera shake tendency of the photographer converges, and specifies that the camera shake tendency of the photographer does not converge, it is set automatically or manually. It is preferable to acquire the shooting conditions and the shooting conditions that can reduce the influence of blur, and execute shooting by the shooting unit under the stricter shooting condition among the acquired shooting conditions. According to this configuration, since shooting is performed immediately under shooting conditions that can avoid blurring, it is possible to shoot images with less blur without time lag.

  Further, the present invention is applied to the above-described photographing apparatus and control method thereof, and a control program for carrying out the present invention can be downloaded via an electric communication line, and such a program can be downloaded to a magnetic recording medium. The present invention can also be implemented in such a manner that it is stored in a computer-readable recording medium such as an optical recording medium or a semiconductor recording medium and distributed.

  According to the photographing apparatus, the control method, the control program, and the recording medium according to the present invention, at least any shake before and after the operation of the photographing instruction operator is detected, and the shake is within a predetermined frequency range. It is determined whether or not there is a shake of a predetermined amplitude or more, and the camera shake tendency of the photographer is specified based on the determination result, and the shooting process according to the specified camera shake tendency is executed. It is possible to easily and quickly specify the camera shake tendency of the photographer without performing a predictive calculation for predicting, and it is possible to take an image with reduced shake.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a digital camera (photographing apparatus) 10 according to an embodiment of the present invention. The digital camera 10 includes a photographing unit 20, a display unit 30, an operation unit 40, an angular velocity detection unit 50, a control unit 60, an external recording / playback unit 70, and a detachable removable memory 80.
The imaging unit (imaging means) 20 includes an optical system 21, an image sensor 22, an analog front end (AFE) unit 23, an image processing unit 24, and a compression / decompression unit 25. The optical system 21 includes a plurality of lenses 21a, a diaphragm 21b, and the like. Under the control of the control unit 60, one of the lenses 21a and the diaphragm 21b is driven to form an object on the light receiving surface of the image sensor 22. .

  The image sensor 22 is an image pickup device including photoelectric conversion elements discretely arranged in a two-dimensional space and charge transfer elements such as a CCD (Charge Coupled Device), and so-called CCD image sensors, CMOS image sensors, and the like are applied. Has been. Under the control of the control unit 60, the image sensor 22 accumulates charges obtained by photoelectrically converting the subject image formed on the light receiving surface for each photoelectric conversion element for a certain period of time, and according to the amount of light received for each photoelectric conversion element. Output electrical signals. The exposure amount of the image sensor 22 is determined by the F value of the diaphragm 21b and the opening time of a mechanical shutter (not shown) provided between the optical system 21 and the image sensor 22, and the exposure amount at the time of shooting is determined by the control unit. 60 is determined based on the set shutter speed and exposure time. Further, the exposure time of the image sensor 22 may be adjusted by electrically controlling the charge accumulation time itself of the image sensor 22.

The AFE unit 23 quantizes the electrical signal output from the image sensor 22 into a digital signal by an AD converter and outputs RAW data, and the image processing unit 24 performs the three primary color (RGB) shading levels with respect to the RAW data. The image data is output after image forming processing for forming a color image having white balance, white balance correction, gamma correction, and the like.
The compression / decompression unit 25 compresses the image data output from the image processing unit 24, and decompresses the compressed image data. The compressed image data is output to the external recording / reproducing unit 70, The recording / reproducing unit 70 records the image data in the removable memory 80 under the control of the control unit 60. Further, the external recording / reproducing unit 70 reads the compressed image data recorded in the removable memory 80 and outputs the compressed image data to the compression / decompression unit 25 under the control of the control unit 60. As the removable memory 80, a semiconductor memory, an optical disk, a magnetic disk, a hard disk, or the like is applied.

  The display unit 30 includes a liquid crystal display, a liquid crystal drive unit, and the like, and functions as an information output unit that displays various information such as an operation menu and a captured image under the control of the control unit 60. The digital camera 10 includes at least a shooting mode for shooting a still image and a playback mode for playing back a shot still image as operation modes. The display unit 30 has a shooting mode in the shooting mode, for example. The image being photographed is displayed by the unit 20, and in the playback mode, the image of the image data read from the removable memory 80 by the external recording / playback unit 70 and decompressed by the compression / decompression unit 25 is displayed. In the present embodiment, a plurality of shooting modes are provided as shooting modes.

  In the plurality of shooting modes, the control unit 60 calculates an exposure time (shutter speed) and an aperture value, and the user (photographer) inputs the exposure time. There are a shutter priority mode to be calculated, an exposure priority mode in which the user inputs the aperture value and the exposure time is calculated by the control unit 60, a program mode in which the user inputs the exposure time and the aperture value, etc. Can be used for shooting.

  The operation unit 40 has a plurality of operators that are operated by a user (photographer), and these operators include a push-down shutter button (an operator for shooting instructions) 41a that instructs shooting, and an operation mode. The shutter button 41a is configured to be able to detect a fully-pressed state where the shutter button 41a is fully pressed and a state where the shutter button 41a is pressed halfway. .

  The angular velocity detection unit 50 functions as a shake detection unit that detects the shake of the digital camera 10, and, as shown in FIG. 2, the angular velocity in the vertical direction (hereinafter referred to as the X axis) of the frame FL to be imaged. And an Y-axis gyro sensor 52 that detects an angular velocity in the left-right direction (hereinafter referred to as the Y-axis). The angular velocity detection unit 50 outputs an angular velocity detection signal having a voltage value corresponding to each angular velocity of the X axis and the Y axis to the control unit 60 by the two gyro sensors 51 and 52.

  The control unit (shooting control means) 60 functions as a computer that controls each unit of the digital camera 10, and as shown in FIG. 1, a CPU 61 that executes various programs and performs arithmetic processing, and this CPU 61 executes. A rewritable flash ROM (hereinafter simply referred to as “ROM”) 62 for storing the control program 100 and various data, and a RAM 63 functioning as a work area for temporarily storing the calculation results of the CPU 61 and various data. I have.

The control program 100 can be recorded and distributed on a computer-readable recording medium 110 such as a magnetic recording medium, an optical recording medium, or a semiconductor recording medium, or can be downloaded from a distribution server on a communication network. Further, the personal computer and the digital camera 10 are communicably connected by a cable or the like, and the control program 100 of the recording medium 110 read by the personal computer is output to the digital camera 10, so that the ROM (storage means) 62 is provided. It is also possible to store the control program 100.
When the shutter button 41a is half-pressed by executing the above control program, the control unit 60 drives the lens 21a of the photographing unit to focus on the subject (auto focus adjustment) or automatic When processing such as exposure (AE) calculation is performed and the shutter button 41a is fully pressed, the aperture 21b is adjusted based on the result of the automatic exposure calculation, and a captured image is acquired by the image sensor 22.

  By the way, when the inventors investigated the tendency of camera shake, in the case of a person who is not accustomed to shooting (hereinafter referred to as an unskilled shooting person), as shown in FIG. In any of the timings T2 at which the button is pressed, a camera shake tendency α1 in which the amount of blur hardly changes before and after the timing T2, and in the case of a person accustomed to shooting (hereinafter referred to as a shooting expert), as shown in FIG. It was found that although the amount of blur increases immediately after the half-pressed timing T1 and the fully-pressed timing T2, the camera shake tendency β1 is smaller at the other times than the unskilled photographer. That is, the amount of blur does not change much before and after the operation of the shutter button 41a for unskilled photographers, whereas the amount of blur greatly changes before and after the operation of the shutter button 41a for the skilled photographers. I found that the blurring converged.

Further, when the inventors analyzed the frequency of camera shake, as shown in FIG. 5, in the case of an imaging expert, the camera shake tendency α2 in which there is no steady bias in the amplitude of the shake, as shown in FIG. In the case of a skilled person, it has been found that there is a camera shake tendency β2 in which a portion PK having a large amplitude in the vicinity of 10 Hz exists constantly.
Therefore, in this embodiment, the frequency of the blur is analyzed and it is determined whether or not there is a bias of the amplitude of the blur in the vicinity of 10 Hz, that is, “blur peculiar to an unskilled person”. The control program 100 includes a photographer discriminating program for executing a photographer discriminating process for discriminating whether or not the photographer is an experienced photographer or an unexperienced photographer.

Next, the operation when the photographer discrimination program is executed will be described. FIG. 7 is a flowchart showing the operation in this case. This shooting program is executed in the shooting mode. First, when the control unit 60 shifts to the shooting mode, it determines whether or not the shutter button 41a is half-pressed (step S1), and waits until it is half-pressed (step S1). S1: NO).
When the shutter button 41a is half-pressed (step S2: YES), the control unit 60 starts a shake acquisition process (step S2). In this shake acquisition process, the control unit 60 acquires an angular velocity detection signal from the angular velocity detection unit 50, stores it in the RAM 63 as shake waveform data corresponding to camera shake, and calculates a shake amount (hereinafter referred to as “shake amount”). The calculation process is repeated a plurality of times to obtain camera shake amounts at a plurality of time points, and an average value (average camera shake amount) MA of the camera shake amount is obtained by calculation and stored in the RAM 63.

  When the shake acquisition processing is completed, the control unit 60 performs Fourier transform (for example, fast Fourier transform) processing on the shake waveform data in order to analyze the frequency of the shake waveform data stored in the RAM 63, and which frequency component is included in the shake waveform data. How much is contained is extracted (step S3). Then, the control unit 60 determines whether or not “blurring peculiar to an inexperienced person”, specifically, whether or not a blur having a predetermined amplitude or more is constantly present in a predetermined frequency range SH ( Step S4).

More specifically, in the process of step S4, the control unit 60 divides the shake waveform data by a predetermined time unit, performs a Fourier transform on each of the divided shake waveform data, and performs a frequency range SH for each data. It is determined whether or not there is a shake having a predetermined amplitude or more, and based on the existence probability, it is determined whether or not “a blur unique to an unskilled photographer” exists constantly. The frequency range SH may be within the range of 4 to 19 Hz, which is the maximum frequency range where “blurring peculiar to unskilled photographers” exists, and from the viewpoint of improving determination accuracy, A range of 5 to 10 Hz, which is a frequency range in which the existence probability of “blurring peculiar to an expert” is high, is preferable.
Instead of the above-described method for dividing the shake waveform data and determining whether or not “blurring peculiar to an unskilled person” exists in each data, a plurality of pieces of shake waveform data are acquired at different times. Even if it is stored in the RAM 63 and it is determined whether or not “blurring peculiar to an inexperienced photographer” exists for each data, whether “blur unique to unexperienced photographer” exists constantly. It can be determined whether or not.

Then, when it is determined in step S4 that “blurring peculiar to unskilled photographers” is present constantly (step S4: YES), the control unit 60 determines that the photographer is unskilled photographers. The camera shake tendency information indicating that the photographer is the camera shake tendency of the photographer is stored in the RAM 63 or the ROM 62 (step S5).
On the other hand, if it is determined in step S4 that “blurring peculiar to an inexperienced photographer” does not exist constantly (step S4: NO), the control unit 60 determines that the photographer is an experienced photographer. The camera shake tendency information indicating that the photographer is the camera shake tendency of the photographer is stored in the RAM 63 or the ROM 62 (step S7). The above is the operation of the photographer discrimination process.
This photographer discrimination process is repeatedly executed in the photographing mode, whereby each time the photographer presses the shutter button 41a halfway, the camera shake tendency information of the photographer is stored and accumulated in the RAM 63 or the ROM 62.

  Subsequently, when the shutter button 41a is fully pressed, the control unit 60 refers to the camera shake tendency information of the photographer, and when the photographer is determined to be a photographer based on this information, If the photographer is determined to be an unskilled photographer, the second photographing process is performed according to the camera shake tendency α1 of the unskilled photographer. Hereinafter, the first photographing process and the second photographing process will be described in detail.

In the case of the first shooting process, the camera shake tendency tends to converge after the full pressing operation of the shutter button 41a (corresponding to the camera shake tendency β1 in FIG. 4). I'm shooting after waiting.
FIG. 8 is a flowchart showing the first photographing process. As shown in this figure, the control unit 60 first starts the shake amount acquisition process to sequentially acquire the shake amount after the shutter button operation (step S10), and the average value of the shake amount (hereinafter referred to as the average shake amount). M1) is obtained by calculation (step S11), and it is determined whether or not the average camera shake amount M1 is equal to or less than the stored average camera shake amount MA before operating the shutter button (step S12).
Here, when the average camera shake amount M1 is larger than the average camera shake amount MA (step S12: NO), the control unit 60 proceeds to the process of step S10, thereby obtaining a new average camera shake amount M1. The processes in steps S10 to S12 for determining whether or not the average camera shake amount M1 is equal to or less than the average camera shake amount MA are repeated.

  In this case, since the camera shake tendency of the photographer is likely to converge after the shutter button operation (the camera shake tendency of the photographer), the average camera shake amount M1 is equal to or less than the average camera shake amount MA before the shutter button operation. In this case, the control unit 60 executes shooting under the shooting conditions (exposure time, aperture value) automatically set by the control unit 60 or manually set by the user (step S13). As a result, it is possible to shoot under optimum shooting conditions at the timing when the amount of blurring is minimized, and it is possible to shoot a high-quality image with little blurring. The above is the first photographing process.

Next, the second photographing process will be described. In the case of the second shooting process, the camera shake tendency of the photographer is likely not to converge (corresponding to the camera shake tendency α in FIG. 3), and thus a shooting condition that can reduce the influence of the shake determined from the amount of shake is obtained. The photographing is performed under the stricter one of the photographing conditions and the automatically set photographing conditions.
FIG. 9 is a flowchart showing the second photographing process. In the present embodiment, the case of setting the exposure time among the shooting conditions is illustrated, but the aperture value may be set without being limited to the exposure time.
As shown in FIG. 9, the control unit 60 first acquires an allowable camera shake amount setting value L2 described in advance in the photographing program (step S20), and stores the average camera shake amount MA stored from the allowable camera shake amount setting value L2. And a shake avoidance exposure time TA capable of avoiding shake is set based on the division value (step S21).

Next, the control unit 60 obtains an exposure time (referred to as an automatic exposure time) TB in the case of automatic exposure (step S22), and determines whether or not the automatic exposure time TB is equal to or less than the shake avoidance exposure time TA ( Step S23). When the automatic exposure time TB is equal to or less than the shake avoidance exposure time TA (step S23: YES), the control unit 60 sets the exposure time actually used as the automatic exposure time TB (step S24), while the automatic exposure time TB When the time TA exceeds the shake avoidance exposure time TB (step S23: NO), the actual exposure time is set to the automatic exposure time TA. Thereafter, the control unit 60 performs shooting under shooting conditions including the set exposure time (step S25).
In this way, shooting is performed with an exposure time equal to or shorter than the blur avoidance exposure time TA that can avoid blurring, so that even when the amount of blurring is relatively large, it is possible to shoot images with little blurring and shutter button operation. Since shooting is performed immediately afterward, a delay in shooting timing (time lag) can be reliably avoided. The above is the second imaging process.

As described above, in the present embodiment, it is determined whether or not there is “blurring peculiar to an unskilled photographer” by performing frequency analysis on blurring after half-pressing operation of the shutter button 41a, and based on this determination result. In addition, since the camera shake tendency of the photographer is determined to be the tendency (convergent tendency) β1 of the photographer or the tendency (non-convergence tendency) α1 of the photographer unskilled, the prediction calculation for predicting the camera shake tendency is performed. In addition, the camera shake tendency of the photographer can be identified easily and quickly.
In addition, in the present embodiment, since it is determined whether or not “blurring peculiar to an inexperienced photographer” exists constantly, the “unexperienced photographer” is rarely used even though the photographer is an experienced photographer. Even if a blur similar to the “specific blur” occurs, the occurrence frequency is low, so that it is possible to avoid a case where the photographer is erroneously determined to be an unskilled photographer.

  In general, the half-pressing operation of the shutter button 41a is performed more frequently than the full-pressing operation of the shutter button 41a. Therefore, as compared with the case where the camera shake tendency information of the photographer is acquired from the camera shake before and after the full-pressing operation, It is possible to increase the number of sampling of camera shake tendency information. Accordingly, the determination accuracy is improved by determining whether the camera shake tendency of the photographer is that of the photographed person or the unskilled person based on the large number of sampled camera shake tendency information, and the first photographing process and the first photographing process are performed. Of the two image capturing processes, it is possible to select an image capturing process that is optimal for the photographer to capture an image without blurring.

  Specifically, when determining the camera shake tendency of a photographer, a method of simply adopting the most camera shake tendency information among a large number of sampled camera shake tendency information, the latest (the most recent period or the immediately preceding few samples) of camera shake What is necessary is just to apply the method which employ | adopts the camera shake tendency information with the largest amount among tendency information, the method which weights the nearest thing, and employs the camera shake tendency information with the highest specific gravity. By adopting the above method, for example, even when the photographer is actually a photographer, the photographer is regarded as an unskilled photographer even when the camera shake tendency is rarely the same as that of the unskilled photographer. It is possible to further avoid the case of erroneous determination.

  Further, in this embodiment, when the camera shake tendency of the photographer is the photographer's tendency β1, since shooting is performed immediately when the camera shake tendency converges, the camera shakes under appropriate shooting conditions while suppressing the time lag. It is possible to take an image with a small amount. Further, when the camera shake tendency of the photographer is the tendency α1 of the unskilled photographer, since shooting is performed immediately under shooting conditions capable of avoiding the shake, it is possible to shoot an image with less blur without time lag.

(Application examples)
In the above-described embodiment, the case where the shake after the shutter button 41a is half-pressed is detected and the frequency analysis is performed has been described. In short, it is only necessary to perform the frequency analysis on the shake when the photographer holds the camera. It is possible to determine whether or not the photographer is a photographer or an unskilled photographer by detecting at least any blur before and after the operation of 41a (including half-press and full-press) and performing frequency analysis. is there.
In the above-described embodiment, the case of detecting camera shake in the vertical direction (X-axis) and the horizontal direction (Y-axis) is illustrated. However, camera shake in the depth direction (Z-axis) may be detected. Further, camera shake in any one of the above directions may be detected.
Further, in the above-described embodiment, the case where the present invention is applied to a digital camera has been illustrated. However, the present invention is not limited to this, and can be applied widely to devices in which blurring is a problem. The present invention can be widely applied to a photographing apparatus, and specifically, can be applied to a mobile phone with a camera, a silver salt camera, a PDA with a camera or an external camera attached thereto, a notebook computer, and the like.
