Description

The present invention relates to an imaging device that assists in panning.

There is panning as a shooting technique that expresses the sense of speed of a moving subject. The purpose of the photographing technique is to make a moving subject stand still and let the background flow by panning the camera according to the movement of the subject.

Here, in the above-mentioned shooting technique, the photographer needs to pan according to the movement of the subject, but the panning speed is too fast or too slow, so that there is a difference between the moving speed of the subject and the panning speed. If it occurs, the image may be blurred even to the subject. To solve such a problem, panning assist has been proposed as a technique for assisting the photographer in panning photography. The panning assist is a method of absorbing the difference between the moving speed of the subject and the panning speed by moving the shift lens for image stabilization based on the panning speed and the motion vector of the subject detected from the image.

Patent Document 1 discloses a method for succeeding in panning by detecting a difference between the speed of a subject and the speed at which the camera is shaken and correcting the amount of deviation corresponding to the difference by using a camera shake correction function. There is. In Patent Document 2, by changing the output timing of the shake detecting means according to the exposure time and the frame rate, the motion vector amount of the subject image and the output timing of the shake detecting means are matched, and the detection accuracy of the moving speed of the subject is matched. Is disclosed how to increase.

If the motion vector and the lens angular velocity whose detection timings do not match each other are used in the panning assist, the wrong subject angular velocity is calculated, which may cause performance deterioration or operation abnormality. Therefore, in order to improve the performance of the panning assist by the interchangeable lens camera system, it is necessary to appropriately manage the timing of the motion vector and the lens angular velocity.

The panning assist control unit 134 (calculation means) is provided in the system control unit 130, and controls the panning assist processing of the camera body 100. The panning assist function can be executed only when the live view shooting mode is set and the attached interchangeable lens 200 supports panning assist. When the panning assist function cannot be executed, the panning assist control unit 134 controls only the flow amount of the image according to the panning assist mode. Specifically, the panning assist control unit 134 controls the shutter so that the deflection angle during exposure becomes an arbitrary amount based on the angular velocity information (lens angular velocity information) obtained from the angular velocity detection unit 208 of the interchangeable lens 200. The amount is notified to the AE control unit 132, and only the flow amount of the image is controlled. When the camera body 100 is equipped with an angular velocity detection unit (not shown), the angular velocity information can also be obtained from this angular velocity detection unit.

On the other hand, when the panning assist function can be executed, the panning assist control unit 134 instructs the interchangeable lens 200 whether or not the panning assist processing can be executed according to the panning assist mode.

Further, the panning assist control unit 134 sets the lens based on the frame rate, the shutter speed, and the like so that the lens angular velocity detection period coincides with (corresponds to) the motion vector detection period (first period , first timing ). The set value of the angular velocity detection period ( second period, second timing ) is calculated. The subject angular velocity information and the set value of the lens angular velocity detection period are transmitted to the interchangeable lens 200 via the lens communication control unit 133 and the I / F 120. At this time, the set value of the lens angular velocity detection period includes the detection period ID (detection period ID information). The detection period ID information (first ID information) is added so that the panning assist control unit 134 determines in what period the lens angular velocity received from the interchangeable lens 200 is the acquired angular velocity. Therefore, the angular velocity information also includes the detection period ID (detection period ID information), and the detection period ID information (second ID information) and the angular velocity information are associated with each other and transmitted to the camera body 100.

The camera body 100 assigns a detection period ID (first ID information) to the motion vector detection period (first period), and associates the motion vector (motion vector amount) detected during that period with the detection period ID. Remember (associate). The motion vector and the corresponding detection period ID are stored in, for example, an internal memory (not shown) of the system control unit 130 or a memory 107. Further, the camera body 100 adds the assigned detection period ID (first ID information) to the set value of the lens angular velocity detection period calculated so as to match the motion vector detection period. Then, the camera body 100 transmits the set value of the lens angular velocity detection period and the detection period ID to the interchangeable lens 200.

The interchangeable lens 200 stores the detection period ID received from the camera body 100 as angular velocity information in association with the angular velocity detected based on the set value of the lens angular velocity detection period received from the camera body 100. The angular velocity information is stored in, for example, an internal memory (not shown) of the lens control unit 210 or a memory 212. Further, the interchangeable lens 200 transmits angular velocity information including a detection period ID (second ID information) to the camera body 100 in response to a request from the camera body 100. When the camera body 100 calculates the subject angular velocity information, the detection period ID (first ID information) associated with the motion vector and the detection period ID (corresponding to the angular velocity information) included in the angular velocity information (corresponding to the angular velocity information). The second ID information) is compared. As a result, the camera body 100 determines whether or not the lens communication can be performed at the expected timing.

Send a drive command, etc. For example, consider a case where the interchangeable lens 200 set in the live view shooting mode and mounted is compatible with panning assist. In this case, when the imaging synchronization signal is input from the timing generation unit 104, the lens communication control unit 133 performs synchronization signal communication for notifying the communication start delay time from the imaging synchronization signal to the start of communication. When the exposure by the shutter switch 116 (SW2) is completed, the lens communication control unit 133 receives the panning assist result information from the interchangeable lens 200.

When the interchangeable lens 200 supports panning assist and the panning assist mode is effective, the panning assist control unit 134 determines that the panning assist processing is to be performed, and proceeds to step S305. On the other hand, if the panning assist control unit 134 determines that the panning assist processing is not performed, the process returns to step S301.

In step S305, the panning assist control unit 134 sets the lens angular velocity detection period so that the motion vector detection period and the angular velocity detection period match (correspond to) based on the exposure setting of the next frame and the like. , Calculated as the relative time from the imaging synchronization signal. The calculated angular velocity detection period setting value is transmitted to the interchangeable lens 200 in step S209 described above. The set value of the lens angular velocity detection period includes the detection period ID information (first ID information). The detection period ID information is added so that the panning assist control unit 134 determines in which period the angular velocity received from the interchangeable lens 200 is the acquired angular velocity. Therefore, the angular velocity information also includes the detection period ID information (second ID information), and the detection period ID information and the angular velocity information are linked to each other and transmitted to the camera body 100.

FIG. 4 shows the operation of the live view exposure processing of the camera body 100 in the live view shooting mode and when the attached interchangeable lens 200 supports panning assist. The live view exposure process is a process started by an exposure start instruction (shooting start instruction) via the shutter switch 116 (SW2) in the live view shooting mode.

First, in step S401, the system control unit 130 notifies the interchangeable lens 200 of the exposure start timing (shooting start timing) by communication via the lens communication control unit 133. Subsequently, in step S402, the system control unit 130 controls the shutter control unit 110 and the image sensor 102 to perform the exposure process and acquire the image data. The image data is held in the memory 107 via the image processing unit 140 and the memory control unit 105.

Subsequently, in step S403, the lens communication control unit 133 determines whether or not to perform the panning assist process. When the interchangeable lens 200 supports panning assist and the panning assist mode is effective, the lens communication control unit 133 determines that the panning assist processing is to be performed, and proceeds to step S404. On the other hand, if the panning assist process is not performed, the process proceeds to step S405.

In step S404, the lens communication control unit 133 performs communication for receiving the panning assist result information from the interchangeable lens 200. Here, the lens communication control unit 133 acquires the result of the vibration isolation control during exposure (follow shot assist result) executed based on the angular velocity information of the subject.

In step S405, the system control unit 130 creates EXIF information added to the image file. The EXIF information is recorded in the memory 107 via the memory control unit 105. In this embodiment, the EXIF information includes the panning assist result information received in step S404, as well as the lens information, the shutter speed, the shooting conditions (camera mode) such as the aperture value, and the like.

Subsequently, in step S406, the system control unit 130 controls the image processing unit 140 to create an image file from the image data and the EXIF information. Further, the system control unit 130 holds the image data in the memory 107 via the memory control unit 105, and then records the image data in the recording unit 108.

By performing the above processing, the result of the panning assist performed at the time of exposure can be acquired from the interchangeable lens 200, and the panning assist result is recorded in the acquired image data or displayed on the image display unit 106. It becomes possible to do.

First, in step S501, the lens control unit 210 stores the time when the communication is performed by storing the current time of the free run timer used for time management in the interchangeable lens 200. This time is stored in the internal memory (not shown) of the lens control unit 210 or the memory 212.

Subsequently, in step S502, the lens control unit 210 determines whether or not communication is performed by the communication data length of the predetermined synchronization signal communication (whether or not all data transmission / reception is completed). If the communication (transmission / reception) of all data is not completed, step S502 is repeated until the communication of all data is completed. On the other hand, when the communication of all data is completed, the process proceeds to step S503. In step S503, the lens control unit 210 subtracts the delay time (synchronous signal delay time) included in the received data of the synchronous signal communication from the time (time when the communication is performed) stored in step S501. This makes it possible to calculate (set) the time of the in-lens imaging synchronization signal that matches the imaging synchronization signal timing in the camera body 100.

By performing the above processing, the interchangeable lens 200 can know the in-lens imaging synchronization signal time that coincides with the imaging synchronization signal timing in the camera body 100.

FIG. 6 shows when the interchangeable lens 200 receives the set value communication of the lens angular velocity detection period from the camera body 100 in the live view shooting mode and when the mounted interchangeable lens 200 supports panning assist. Indicates the process to be started.

First, in step S601, the lens control unit 210 determines whether or not communication is performed by the communication data length of the set value communication of the lens angular velocity detection period determined in advance (whether or not all data transmission / reception is completed). If the communication (transmission / reception) of all data is not completed, step S601 is repeated until the communication of all data is completed. On the other hand, when the communication of all data is completed, the process proceeds to step S602.

In step S602, the lens control unit 210 determines the lens angular velocity detection period included in the received data of the set value communication of the lens angular velocity detection period and the time of the in-lens imaging synchronization signal calculated in step S503 described above. Set the lens angular velocity detection period. The lens control unit 210 acquires the lens angular velocity in the lens angular velocity detection period from the angular velocity detection unit 208. Then, the lens control unit 210 adds the detection period ID information included in the set value communication of the lens angular velocity detection period and the angular velocity information acquisition time to the angular velocity information and stores them in the internal memory or the memory 212. Preferably, the lens control unit 210 stores in the memory 212 that the panning assist is effective.

By performing the above processing, the interchangeable lens 200 can set a lens angular velocity detection period that coincides with the motion vector detection period in the camera body 100.

Next, with reference to FIG. 7, the reception process of the subject angular velocity communication by the interchangeable lens 200 will be described. FIG. 7 is a flowchart of the reception process of the subject angular velocity communication by the interchangeable lens 200. FIG. 7 shows a process started when the interchangeable lens 200 receives the subject angular velocity communication from the camera body 100 in the live view shooting mode and the mounted interchangeable lens 200 supports panning assist. ing.

First, in step S701, the lens control unit 210 prepares (holds) the angular velocity information and the detection period ID information in the transmission buffer in order to transmit the angular velocity information and the detection period ID information stored in step S602 to the camera body 100. .. Subsequently, in step S702, the lens control unit 210 determines whether or not communication is performed by the communication data length of the predetermined subject angular velocity communication (whether or not all data transmission / reception is completed). If the transmission / reception (communication) of all data is not completed, step S702 is repeated until the communication of all data is completed. On the other hand, when the communication of all data is completed, the process proceeds to step S703. In step S703, the lens control unit 210 stores the subject angular velocity information in the internal memory or the memory 212 in preparation for the exposure start timing.

By performing the above processing, the interchangeable lens 200 can set a lens angular velocity detection period that coincides with the motion vector detection period of the camera body 100.

Next, the reception process of the exposure start timing communication by the interchangeable lens 200 will be described with reference to FIG. FIG. 8 is a flowchart of the reception process of the exposure start timing communication by the interchangeable lens 200. FIG. 8 shows when the interchangeable lens 200 receives the exposure start timing communication from the camera body 100 in the live view shooting mode and the mounted interchangeable lens 200 is compatible with the panning assist. Indicates the processing to be performed.

First, in step S801, the lens control unit 210 determines whether or not the exposure should be subjected to the panning assist process. For example, the determination is made with reference to the area of the memory 212 to be written in step S602. When carrying out the panning assist process, the process proceeds to step S802. On the other hand, if the panning assist process is not performed, the process proceeds to step S804.

In step S802, the lens control unit 210 (prediction means) predicts the subject angular velocity at the current time from the subject angular velocity information stored in step S703 and the current time (predicted angular velocity of the subject before shooting a still image). To calculate). When the current time is T, the subject angular velocity at the current time T is V, the subject angular velocity and subject angular velocity included in the subject angular velocity information, and the angular velocity information acquisition time are v, a, and t, respectively, the lens control unit 210 , Perform the prediction calculation as represented by the following equation (1).

However, the prediction operation is not limited to the equation (1), and other equations and methods may be used.

Subsequently, in step S803, the lens control unit 210 controls the anti-vibration control unit 209 using the subject angular velocity at the current time, and executes the panning assist process. For example, the lens control unit 210 acquires the vibration isolation amount g (panning amount) from the angular velocity detection unit 208, and calculates the panning assist vibration isolation amount G using the following equation (2).

However, the calculation method of the panning assist vibration isolation amount G is not limited to this. By controlling the vibration isolation control lens 204 so as to cancel the panning assist vibration isolation amount during exposure, it is possible to make a moving subject still.

In step S804, the lens control unit 210 performs the vibration isolation process using only the vibration isolation amount from the angular velocity detection unit 208, so that the normal camera shake correction is performed.

By performing the above processing, the interchangeable lens 200 can transmit the panning assist result applied at the time of exposure to the camera body 100, and the camera body 100 records the panning assist result in the acquired image data. can do.

Next, with reference to FIG. 9, the reception process of the panning assist result communication by the interchangeable lens 200 will be described.

Subsequently, in step S902, the lens control unit 210 determines whether or not communication is performed by the communication data length of the predetermined panning assist result communication (whether or not all data transmission / reception is completed). If the communication (transmission / reception) of all data is not completed, step S902 is repeated until the communication of the previous data is completed. On the other hand, when the communication of all data is completed, the reception process of this flow is terminated.

By performing the above processing, the interchangeable lens 200 can obtain the subject angular velocity in consideration of the elapsed time from the time when the lens angular velocity detection time is acquired to the start of exposure, and can perform more accurate panning assist. ..

Next, the panning assist process by the camera system 10 (camera body 100 and interchangeable lens 200) will be described with reference to FIG. FIG. 10 is a timing chart of the panning assist process by the camera system 10. FIG. 10 shows the processing timing of the camera system 10 in the panning assist mode when the interchangeable lens 200 mounted in the live view shooting mode supports panning assist.

The image pickup synchronization signal 1001 is a synchronization signal output by the timing generation unit 104. The image pickup storage 1002 is a storage period of the image pickup device 102, and receives the image pickup synchronization signal 1001 and starts reading in order from the upper part of the screen. The synchronous signal communication 1003 is the timing of the synchronous signal communication implemented in step S208 of FIG. The lens angular velocity detection period set value communication 1004 is the timing of the lens angular velocity detection period set value communication performed in step S209 of FIG.

The subject angular velocity communication 1005 is the timing of the subject angular velocity communication performed in step S308 of FIG. The lens angular velocity detection period 1006 is the lens angular velocity detection period set in step S602 of FIG. When the lens angular velocity detection period is completed, the lens angular velocity corresponding to that period is calculated, and the detection period ID information included in the set value communication of the lens angular velocity detection period and the angular velocity information acquisition time are added to the angular velocity information. And remember. The angular velocity output 1007 is an output from the angular velocity detection unit 208. The lens control unit 210 samples the angular velocity output 1007 during the lens angular velocity detection period 1006.

For example, the synchronization signal communication 1011 is executed in response to the imaging synchronization signal 1010, and the lens control unit 210 calculates the in-lens imaging synchronization signal time that matches (corresponds to) the imaging synchronization signal 1010. After that, the set value communication 1012 of the lens angular velocity detection period is carried out. As a result, the set value (angular velocity detection period) of the lens angular velocity detection period calculated to match the motion vector detection period 1013 (first period) in the exposure setting process of the previous imaging synchronization signal is exchanged. It is transmitted to the lens 200. Further, the detection period ID 1020 (first ID information) assigned to the motion vector detection period 1013 in a state associated with this set value is transmitted to the interchangeable lens 200. As a result, the lens control unit 210 can set the lens angular velocity detection period 1014 (angular velocity detection period). The angular velocity information obtained by completing the lens angular velocity detection period 1014 is notified to the camera body 100 by the subject angular velocity communication 1015 together with the detection period ID obtained by the set value communication 1012 of the lens angular velocity detection period. The panning assist control unit 134 calculates the subject angular velocity information based on the angular velocity information at that time, the motion vector information obtained in the motion vector detection period 1013 (first period), and the detection period ID.

By repeating the above processing, it becomes possible to continue transmitting accurate subject angular velocity information to the interchangeable lens 200.

As described above, in the present embodiment, the imaging device (control device) includes a motion vector detection means (motion vector detection unit 141), a calculation means (follow-up assist control unit 134), and a communication means (lens communication control unit 133). Has. The motion vector detecting means detects the motion vector in the first period (motion vector detection period 1013). The calculation means sets the detection period of the angular velocity by the angular velocity detection means (angular velocity detection unit 208) based on the first period (the detection period of the angular velocity is the same as the first period or a predetermined period corresponding to the first period. Is the period of). The communication means transmits the detection period of the angular velocity and the first ID information corresponding to the first period in association with each other. Further, the communication means receives the angular velocity detected during the detection period of the angular velocity and the second ID information corresponding to the angular velocity in association with each other. When the first ID information and the second ID information match (correspond to) each other, the calculation means uses the motion vector detected in the first period corresponding to the first ID information and the second ID information. The angular velocity information of the subject is calculated based on the angular velocity corresponding to (S306, S307). Preferably, when the first ID information and the second ID information do not correspond to each other, the calculation means uses the motion vector and the second ID information detected in the first period corresponding to the first ID information. The angular velocity information of the subject is not calculated using the corresponding angular velocity (S306).

When the first ID information and the second ID information match, it indicates that the lens communication is being performed at an appropriate timing. On the other hand, when the first ID information and the second ID information do not match, it indicates a state in which lens communication cannot be performed at an appropriate timing due to exhaustion of the lens communication band or concentration of CPU load. .. Therefore, the camera body 100 compares the first ID information transmitted to the interchangeable lens 200 with the second ID information received from the interchangeable lens 200 to determine whether or not the lens communication is properly performed. It can be determined.

Further, in this embodiment, the lens device (control device) has a communication means (I / F220) and an angular velocity detecting means (angular velocity detecting unit 208). The communication means receives the angular velocity detection period set based on the first period, which is the motion vector detection period, and the first ID information corresponding to the first period in association with each other. The angular velocity detecting means detects the angular velocity during the detection period of the angular velocity. The communication means transmits the angular velocity and the second ID information corresponding to the angular velocity in association with each other. The first ID information and the second ID information match each other.

In this embodiment, the set value of the lens angular velocity detection period to which the detection period ID information is added is communicated from the camera body to the interchangeable lens. Further, the interchangeable lens communicates with the camera body by adding the detection period ID information to the angular velocity information detected based on the set value of the lens angular velocity detection period. As a result, the camera body can determine the detection timing of the angular velocity information acquired based on the detection period ID information. Therefore, it is possible to realize an interchangeable lens camera system equipped with a panning assist function capable of accurately calculating the subject angular velocity.

Next, Example 2 of the present invention will be described. In this embodiment, a panning assist function capable of more accurate subject angular velocity calculation is realized. The basic configuration of this embodiment is the same as that of the first embodiment.

In the first embodiment, when the detection period IDs do not match, the subject angular velocity calculation (step S307) is not performed. However, as a cause of the mismatch of the detection period IDs, there is a possibility that the lens communication cannot be performed at the timing assumed in advance due to the exhaustion of the lens communication band and the concentration of the CPU load. Therefore, there is a possibility that the subject angular velocity calculation will succeed by using the data acquired in the past or by re-executing the process (performing the retry process). Therefore, the camera system of this embodiment performs a retry process when the detection period ID information does not match.

The exposure setting process of the camera body 100 in this embodiment will be described with reference to FIG. FIG. 11 is a flowchart of the exposure setting process of the camera body 100, in the case where the camera body 100 is in the live view shooting mode and the attached interchangeable lens 200 supports panning assist. The operation of 100 exposure setting processing is shown. The exposure setting process is a process performed for each frame in the live view shooting mode, and is a process for controlling the exposure of the next frame. Since steps S1101 to S1105 in FIG. 11 are the same as steps S301 to S305 in FIG. 3, their description will be omitted.

In step S1106, the panning assist control unit 134 determines whether or not the detection period ID corresponding to the detection period of the motion vector amount to be used and the detection period ID included in the angular velocity information received from the interchangeable lens 200 coincide with each other. To judge. If they match each other, the process proceeds to step S1110. On the other hand, if they do not match each other, the process proceeds to step S1107.

In step S1107, the panning assist control unit 134 has past data that matches the detection period ID corresponding to the detection period of the motion vector amount to be used and the detection period ID included in the plurality of angular velocity information received so far. Determine if there is. If there is a detection period ID that matches the detection period ID corresponding to the detection period of the motion vector amount among the detection period IDs included in the plurality of angular velocity information received in the past, the matching angular velocity information is set for calculation. Correct and proceed to step S1110. On the other hand, if there is no matching detection period ID, the process proceeds to step S1118.

In step S1108, the panning assist control unit 134 again receives (re-acquires) the angular velocity information (lens angular velocity information) including the detection period ID from the interchangeable lens 200. Subsequently, in step S1109, the panning assist control unit 134 determines whether or not the detection period ID reacquired in step S1108 and the detection period ID corresponding to the detection period of the motion vector amount to be used coincide with each other. To do. If they match each other, the process proceeds to step S1110. On the other hand, if they do not match each other, the process proceeds to step S1111.

In step S1110, the panning assist control unit 134 calculates the angular velocity information of the subject based on the lens information such as the angular velocity information and the focal length received from the interchangeable lens 200 and the motion vector amount input from the image processing unit 140. To do. The subject angular velocity information includes the subject angular velocity and the subject angular acceleration. Further, the panning assist control unit 134 inputs the calculated angular velocity information of the subject to the lens communication control unit 133. The angular velocity information of the subject includes the angular velocity information acquisition time corresponding to the angular velocity information used for the calculation. In step S1111, the lens communication control unit 133 performs subject angular velocity communication in order to transmit subject angular velocity information to the interchangeable lens 200, and returns to step S1101. In this embodiment, the received data of the subject angular velocity communication includes the angular velocity information including the detection period ID information.

By performing the above processing, it is possible to control the exposure of the next frame and set the lens angular velocity detection period for notifying the interchangeable lens 200 with the next imaging synchronization signal. Further, the subject angular velocity can be notified to the interchangeable lens 200, and the angular velocity information can be acquired from the interchangeable lens 200.

As described above, in the present embodiment, preferably, the communication means (lens communication control unit 133) includes the second angular velocity detected in a period different from the angular velocity and the third ID information corresponding to the second angular velocity. Are associated with each other and received. In the calculation means (follow-up assist control unit 134), the first ID information and the second ID information do not correspond to each other, and the first ID information and the third ID information match each other. In this case, the angular velocity information of the subject is calculated using the angular velocity corresponding to the third ID information. That is, the calculation means calculates the angular velocity information of the subject based on the motion vector detected in the first period corresponding to the first ID information and the angular velocity corresponding to the third ID information. Preferably, the second angular velocity corresponding to the third ID information is detected in a period after the angular velocity corresponding to the second ID information.

Preferably, the arithmetic means is the angular velocity detecting means when the first ID information and the second ID information do not correspond to each other and when the first ID information and the third ID information do not correspond to each other. Controls to reacquire the angular velocity (S1108). The communication means receives the reacquired angular velocity and the fourth ID information corresponding to the reacquired angular velocity in association with each other. Then, when the first ID information and the fourth ID information match each other, the calculation means corresponds to the motion vector and the fourth ID information detected in the first period corresponding to the first ID information. The angular velocity information of the subject is calculated based on the angular velocity. More preferably, when the first ID information and the fourth ID information do not correspond to each other, the calculation means means that the motion vector and the fourth ID information detected in the first period corresponding to the first ID information correspond to each other. The angular velocity information of the subject is not calculated using the angular velocity corresponding to (S1109).

In this embodiment, the set value of the lens angular velocity detection period to which the detection period ID information is added is communicated from the camera body to the interchangeable lens. Further, the interchangeable lens communicates with the camera body by adding the detection period ID information to the angular velocity information detected based on the set value of the lens angular velocity detection period. As a result, the camera body can determine the detection timing of the angular velocity information acquired based on the detection period ID information. Further, in this embodiment, the retry process is performed when the detection period ID information does not match each other. Therefore, it is possible to realize an interchangeable lens camera system equipped with a panning assist function capable of more accurate calculation of the subject angular velocity.
