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 blur detected after the shutter button is fully pressed and the shake tolerance are compared. If the amount of shake is greater than the shake tolerance, the above shake tolerance is reduced from the normal shooting mode. There is a camera that takes a picture when the camera shifts to the shake reduction mode to be changed to and the shake amount falls below the 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 is fully pressed is detected (for example, Patent Documents). 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 image capturing apparatus that performs autofocus adjustment when the shutter button is half-pressed and performs image capturing after the shutter button is fully pressed, and a shake that detects a blur amount of the image capturing means.

  In the above invention, it is preferable that the photographing control unit compares the amount of blurring before and after the half-pressing operation of the shutter button, and determines whether or not the camera shake tendency of the photographer tends to converge based on the comparison result. According to this configuration, it is possible to easily identify the camera shake tendency of the photographer as compared with the case of performing prediction calculation for predicting the camera shake tendency.

  In the above invention, the photographing control means determines the camera shake tendency of the photographer every time the shutter button is half-pressed, accumulates information indicating the camera shake tendency, and based on the accumulated information, It is preferable to identify the tendency of camera shake. According to this configuration, the information indicating the camera shake tendency of the photographer is accumulated for each half-pressing operation that is generally performed more frequently than the full-pressing operation of the shutter button. Since the camera shake tendency of the photographer is specified based on this, the determination accuracy is improved.

  In addition, according to the present invention, in the control method of the photographing apparatus, at least one amount of blurring before and after the shutter button is half-pressed is obtained, and the tendency of camera shake of the photographer is specified based on the amount of shaking, and the shutter button is fully pressed. If it is, the photographing process according to the specified camera shake tendency is executed. According to the present invention, at least one of the shake amounts before and after half-pressing of the shutter button is obtained, the camera shake tendency of the photographer is specified based on the shake amount, and the specified when the shutter button is fully pressed Since the shooting process according to the camera shake tendency is executed, the camera shake tendency of the photographer can be easily identified, and the shooting process according to the specified camera shake tendency is executed, so that an image with reduced blur can be taken. become.

  In addition to being applied to the above-described photographing apparatus and its control method, the present invention makes it possible to download a control program for carrying out the present invention via an electric communication line, or to store such a program on 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 imaging device, the control method, the control program, and the recording medium according to the present invention, at least one of the shake amounts before and after the shutter button is half-pressed is acquired, and the camera shake tendency of the photographer is specified based on the shake amount When the shutter button is pressed all the way down, the shooting process according to the specified camera shake tendency is executed. Therefore, the camera shake tendency of the photographer can be easily identified, and the shooting process according to the specified camera shake tendency is executed. Therefore, it is possible to take an image with reduced blur.

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 operating elements operated by a user, and these operating elements include a push-down shutter button (operating element for shooting instruction) 41a for instructing shooting, operation mode selection and shooting. There are operation keys for setting conditions and the like, and the shutter button 41a is configured to be able to detect a fully-pressed state where the shutter button 41a is pressed down to the lowest part and a state where the shutter button 41a is pressed half-pressed.

  The angular velocity detection unit 50 functions as a shake amount detecting means for detecting the shake amount of the digital camera 10, and as shown in FIG. 2, the vertical direction of the frame FL to be imaged (hereinafter defined as the X axis). And an Y-axis gyro sensor 52 for detecting the 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 (photographing control means) 60 functions as a computer that controls each unit of the digital camera 10.
As shown in FIG. 1, a CPU 61 that executes various programs and performs arithmetic processing, a control program 100 that is executed by the CPU 61, and a rewritable flash ROM (hereinafter simply referred to as “ROM”) 62 that stores various data, A RAM 63 functioning as a work area for temporarily storing calculation results of the CPU 61 and various data is provided.

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 when the button is pressed, the camera shake tendency α is almost the same before and after that, and in the case of a person familiar with 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 β 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.
Therefore, in this embodiment, it is determined whether the camera shake tendency corresponds to the above-mentioned two camera shake tendencies α and β based on the amount of shake before and after the half-pressing operation of the shutter button 41a. The control program 100 includes a photographer discrimination program for executing a photographer discrimination process for discriminating whether or not the person is an unskilled person.

  Next, the operation when the photographer discrimination program is executed will be described. FIG. 5 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 performs a shake amount acquisition process (step S1). In this shake amount acquisition process, the control unit 60 takes in an angular velocity detection signal from the angular velocity detection unit 50, calculates a shake amount corresponding to camera shake (hereinafter referred to as “shake amount”), and repeats this calculation process a plurality of times. Thus, the amount of camera shake at a plurality of points in time is acquired and stored in the RAM 63.

Next, the control unit 60 determines whether or not the shutter button 41a is half-pressed (step S2). If the shutter button 41a is not half-pressed (step S2: NO), it is stored in the RAM 63 until it is half-pressed. The camera shake amount is updated to the latest value, and the camera shake amount immediately before a predetermined number of samples is stored in the RAM 63.
On the other hand, when the shutter button 41 a is half-pressed (step S <b> 2: YES), the control unit 60 calculates an average value (average camera shake amount) MA of a plurality of samples before half-press stored in the RAM 63. While obtaining by calculation (step S3), the camera shake amount acquisition process is continued, the camera shake amounts at a plurality of time points (multiple samples) after half-pressing are acquired, and the average value (average camera shake amount) MB after this half-pressing is obtained. Is obtained by calculation (step S4).

  Subsequently, the control unit 60 obtains a value X obtained by dividing the average camera shake amount MB after half-pressing by the average camera shake amount MA before half-pressing, and determines whether the divided value X is equal to or greater than a predetermined threshold L1. (Step S5). Here, the threshold value L1 is a determination reference value for determining whether the amount of blurring before and after the shutter button 41a is half-pressed is that of an experienced photographer or an unexperienced photographer. Since the amount of blur increases immediately after the operation, the divided value X is a value of 1 or more, and the unexperienced photographer hardly changes the blur amount before and after the half-pressing operation. For example, a value of 1.5 or more is applied to the threshold value L1.

When the divided value X of the average camera shake amount MB and the average camera shake amount MA is equal to or greater than the threshold value L1 (step S5: YES), the control unit 60 determines that the photographer is a photographer and the photographer takes a photograph. Camera shake tendency information indicating that the camera shake tendency of the skilled person is stored in the RAM 63 or the ROM 62 (step S6). When the division value X is less than the threshold value L1 (step S5: NO), the photographer is an unskilled photographer. The camera shake tendency information indicating that the photographer is the camera shake tendency of the unskilled 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 α 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 of the photographer is likely to converge after the full pressing operation of the shutter button 41a (corresponding to the camera shake tendency β in FIG. 4). I'm shooting after waiting.
FIG. 6 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 performs 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. 7 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. 7, the control unit 60 first obtains 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 this embodiment, the camera shake tendency of the photographer is the tendency (converging tendency) β of the photographer based on the blur amount before and after the half-press operation of the shutter button 41a, or the tendency of the unskilled photographer. (Trend that does not converge) Since α is specified, the camera shake tendency of the photographer can be specified easily and quickly without performing a prediction calculation or the like for predicting the camera shake tendency.
Moreover, 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, compared to 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. Among 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 number among tendency information, the method which weights the latest thing and employs the camera shake tendency information with the highest specific gravity, etc. By adopting the above method, for example, even if the photographer is actually a beginner (unexperienced photographer), the photographer is rarely photographed even when the camera shake tendency is the same as that of the photographer. It is possible to avoid the case of erroneous determination as an expert.

  Further, in this embodiment, when the camera shake tendency of the photographer is the tendency β of the photographer, 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 α of the unskilled photographer, since the shooting is performed immediately under shooting conditions that can avoid the shake, it is possible to shoot an image with less blur without time lag.

(Application examples)
In the above-described embodiment, the amount of shake before and after the shutter button 41a is half-pressed is acquired, and the camera shake tendency of the photographer is the camera shake tendency α of the unskilled photographer or the camera shake of the photographed expert based on the ratio of the shake amount before and after. Although the case of determining whether or not the tendency is β has been described, the present invention is not limited to this.
For example, paying attention to the fact that the amount of camera shake before the half-pressing operation of the shutter button 41a is smaller for those skilled in photography than the non-skilled image taking person, only the average amount of camera shake MA before the shutter button 41a is half-pressed. Based on this, the camera shake tendency of the photographer may be determined.
In addition to this, the photographer skilled in the art notices that the amount of blur is instantaneously larger after the half-pressing operation of the shutter button 41a than before the half-pressing operation, and before the half-pressing operation of the shutter button 41a. The average camera shake amount MA and the maximum camera shake value Mmax after a half-press operation may be acquired, and the camera shake tendency of the photographer may be determined based on the ratio between the maximum value Mmax and the average camera shake amount MA.
Furthermore, paying attention to the fact that the amount of camera shake after a half-press operation of the shutter button 41a varies compared with a person unskilled in shooting, the variation (dispersion) in the amount of camera shake after a half-press operation is calculated. It is also possible to determine the camera shake tendency of the photographer based on this value.

  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 in short, the present invention can be widely applied to devices in which the amount of shake is a problem. For example, it can be widely applied to photographing devices other than digital cameras. Specifically, it can be applied to mobile phones with cameras, silver salt cameras, PDAs with a camera or externally attached cameras, and notebook computers. Applicable.
