The digital signal is converted into digital data by a / D converter (not shown), color processing including pixel interpolation processing and γ correction processing is performed by a color process circuit (not shown), and then a digital luminance signal Y and color difference signal Cb , Cr (YUV data). Further, the image data generation unit 4 encodes each of a plurality of frame images constituting the moving image in a predetermined format (for example, MPEG format, motion JPEG format, etc.), and generates moving image image data.
For example, the imaging unit 3 captures a series of operations of a predetermined sport by a subject at a predetermined imaging frame rate (for example, 1000 fps), and the image data generation unit 4 includes a plurality of frame images associated with frame numbers. The image data of the moving image consisting of is generated.
In addition, the image data generation unit 4 transfers the generated image data to the memory 2 used as a buffer memory.

The image recording unit 5 is configured by, for example, a nonvolatile memory (flash memory). The image recording unit 5 records image data of various images encoded by a coding unit (not shown) of the image data generation unit 4 using a predetermined coding method.
Specifically, the image recording unit 5 includes, for example, a plurality of frame images F1 to F6 in which a series of actions of a subject are continuously captured by the imaging unit 3 (see FIGS. 3A to 3F). The image data of the moving image consisting of, the image data of the moving image consisting of a predetermined number of frame images based on a predetermined time point, and the like are recorded.
Further, as will be described later, the image recording unit 5 includes information based on an index set by the index processing unit 6b (described later) of the image analysis unit 6 and an index acquired by the information acquisition unit 6c (described later). You may record the image data etc. of the analyzed moving image which consists of several synthetic | combination frame image G1-G6 (refer FIG.5 (a)-FIG.5 (f)) synthesize | combined to each of the images F1-F6.

  The image recording unit 5 may be configured, for example, such that a recording medium (not shown) is detachable, and controls reading of data from the loaded recording medium and writing of data to the recording medium.

The image analysis unit 6 includes an image acquisition unit 6a, an index processing unit 6b, and an information acquisition unit 6c.
Note that each unit of the image analysis unit 6 includes, for example, a predetermined logic circuit, but the configuration is an example and the present invention is not limited thereto.

The image acquisition unit 6a acquires an image to be processed by the moving image analysis process.
That is, the image acquisition unit (image acquisition unit) 6a acquires an image of a subject that performs a specific operation. Specifically, the image acquisition unit 6a reads, for example, image data of a moving image including a plurality of frame images obtained by continuously capturing the motion of the subject from a predetermined storage unit (for example, the image recording unit 5). Get.
For example, the image acquisition unit 6 a includes a plurality of frame images F <b> 1 to F <b> 1 generated by the image data generation unit 4 after a series of movements of a predetermined sport (for example, golf swing movements) by the subject are captured by the imaging unit 3. The image data of the moving image composed of F6 is read from the image recording unit 5 and acquired as a processing target of the moving image analysis processing.

The index processing unit 6b performs various processing operations such as index setting and position adjustment for analyzing a specific motion of the subject.
That is, the index processing unit (setting unit) 6b sets a plurality of indexes in the image for the plurality of frame images acquired by the image acquisition unit 6a. In addition, the index processing unit (adjustment unit) 6b adjusts the position of the index in the plurality of frame images. Specifically, for example, the index processing unit 6b reads and acquires index data stored as a default in a predetermined storage unit (for example, the memory 2 or the like). In addition, the index processing unit 6b displays the predetermined frame image (for example, the first frame image F1 (see FIG. 3A)) among the plurality of frame images displayed on the display panel 7a. The index position is adjusted in the frame image in accordance with the index position adjustment instruction input based on the predetermined operation of the operation input unit 8.
Here, the index includes a reference line passing through a predetermined portion of the subject. That is, the index processing unit 6b adjusts the position of the reference line so as to pass a predetermined portion of the subject in the frame image based on a predetermined operation of the operation input unit 8 by the user. For example, in the case of a subject performing a golf swing, the index processing unit 6b adjusts the position of the first reference line L1 so as to pass through the waist portion of the subject and the club head portion, and the base portion of the subject's neck The position of the second reference line L2 is adjusted so as to pass through the club head part, and the position of the third reference line L3 is adjusted so as to pass through the waist part of the subject and the base part of the neck.
Further, for example, when adjusting the positions of a plurality of indices such as the first to third reference lines L1 to L3, among these indices, based on a predetermined operation of the operation input unit (designating means) 8 by the user. When the index whose position is to be adjusted is specified, the index processing unit 6b adjusts the position of the specified index.

In addition, the index processing unit 6b sets each index (for example, the first to third reference lines L1 to L3) in a predetermined frame image (for example, the first frame image F1) among the plurality of frame images. Thus, the remaining frame images are similarly set by applying indices to positions corresponding to the indices of the first frame image F1.
Note that the numbers, positions, and the like of the indexes such as the first to third reference lines L1 to L3 described above are merely examples, and are not limited thereto, and can be arbitrarily changed as appropriate.

The information acquisition unit (information acquisition unit) 6c acquires information based on an index for analyzing a specific motion of the subject set in the frame image.
That is, when a plurality of indices are set by the index processing unit 6b in a plurality of frame images, the information acquisition unit 6c acquires information corresponding to each of the plurality of indices. At this time, when the position of the index is adjusted by the index processing unit 6b, the information acquisition unit 6c sequentially acquires information corresponding to the index after the position adjustment. Specifically, each time the position of the reference line as the index set by the index processing unit 6b is adjusted, the information acquisition unit 6c and the reference line after the position adjustment and a predetermined straight line (for example, another reference line) And a predetermined straight line substantially orthogonal to the optical axis direction) (for example, first to third angles A1 to A3) are sequentially acquired as information based on the index.
For example, in the case of a subject performing a golf swing, the information acquisition unit 6c calculates the first angle A1 formed by the first reference line L1 and the horizontal straight line of the image, and corresponds to the first reference line L1. The second angle A2 formed by the second reference line L2 and the first reference line L1 is calculated and acquired as information corresponding to the second reference line L2, and the third reference line L3 A third angle A3 formed by a straight line in the vertical direction of the image is calculated and acquired as information corresponding to the third reference line L3.

  Further, the image analysis unit 6 includes each of the plurality of frame images, the index set by the index processing unit 6b (for example, the first to third reference lines L1 to L3) and the information acquired by the information acquisition unit 6c. (For example, first to third angles A1 to A3, etc.) are combined to generate image data of an analyzed moving image composed of a plurality of combined frame images G1 to G6.

  Each index is prepared according to the handedness of the person who operates, and FIG. 4 is for a right-handed person.

  The display unit 7 displays still images and moving images. Specifically, the display unit 7 includes a display panel 7a and a display control unit 7b.

The display panel 7a displays an image in the display area. Specifically, the display panel 7a displays a live view image while sequentially updating a plurality of image frames generated by imaging the subject by the imaging unit 3 at a predetermined playback frame rate in the still image capturing mode or the moving image capturing mode. L is displayed.
Examples of the display panel 7a include a liquid crystal display panel and an organic EL (Electro-Luminescence) display panel. However, the display panel 7a is an example and is not limited thereto.

  The display control unit 7b performs control to display a predetermined image on the display screen of the display panel 7a based on the image data of a predetermined size read from the image recording unit 5 and decoded by the image analysis unit 6. Specifically, the display control unit 7b includes a VRAM (Video Random Access Memory), a VRAM controller, a digital video encoder, and the like. The digital video encoder reads out the luminance signal Y and the color difference signals Cb and Cr decoded by the image analysis unit 6 and stored in the VRAM (not shown) from the VRAM via the VRAM controller, and stores these data. Originally, a video signal is generated and output to the display panel 7a.

Further, in the moving image analysis process, the display control unit 7b causes the index set by the index processing unit 6b and information based on the index to be superimposed on the frame image and displayed on the display panel 7a.
That is, the display control unit (control unit) 7b displays the index and the information based on the index acquired by the information acquisition unit 6c in association with the plurality of frame images acquired by the image acquisition unit 6a. ) 7a is displayed. Specifically, when a plurality of indexes are set by the index processing unit 6b and information corresponding to each index is acquired by the information acquisition unit 6c, the display control unit 7b displays information corresponding to the plurality of indexes and each index. Are displayed on the display panel 7a.
For example, the display control unit 7b superimposes each of the plurality of frame images, and each of the plurality of indices corresponds to a corresponding color (for example, red for the first reference line L1 and for the second reference line L2). In the case of the third reference line L3, the color is displayed on the display panel 7a. In addition, the display control unit 7b superimposes each of the plurality of frame images, and displays information based on the plurality of indexes on the display panel 7a using colors substantially equal to the corresponding indexes. Specifically, the display control unit 7b sets the first angle A1 to “R: **” in red (R) substantially equal to the first reference line L1, and sets the second angle A2 to the second reference line. As an aspect of “B: **” in blue (B) substantially equal to L2, and as an aspect of “G: **” in green (G) substantially equal to the third reference line L3, the third angle A3 is respectively It is displayed at a predetermined position on the display panel 7a.
In addition, the display control unit 7b is a region corresponding to an angle (for example, first to third angles A1 to A3) formed by a reference line and a predetermined straight line as information based on a plurality of indices (in FIG. 4, A predetermined color may be added to the regions B1 to B3) indicated by dots, and displayed on the display panel 7a.

The operation input unit 8 is for inputting various instructions to the apparatus main body.
Specifically, the operation input unit 8 includes an operation unit (not shown) including up / down / left / right cursor buttons, a determination button, and the like related to selection of a shooting mode, a function, and the like.
When the user operates various buttons on the operation unit, the operation input unit 8 outputs an operation instruction corresponding to the operated button to the central control unit 1. The central control unit 1 causes each unit to execute a predetermined operation (for example, imaging of a subject) in accordance with an operation instruction output from the operation input unit 8 and input.
The operation input unit 8 may include a touch panel (not shown) provided integrally with the display panel 7a of the display unit 7.

Next, the moving image analysis processing will be described with reference to FIGS.
FIG. 2 is a flowchart illustrating an example of an operation related to the moving image analysis process.

  The moving image analysis process described below is performed when a moving image analysis mode is selected from a plurality of operation modes displayed on a menu screen (not shown) based on a predetermined operation of the operation input unit 8 by the user. It is a process to be executed.

<Video analysis processing>
As shown in FIG. 2, first, when a moving image to be processed by the moving image analysis process is specified based on a predetermined operation of the operation input unit 8 by the user, the image acquisition unit 6a displays the specified moving image ( For example, the image data of the moving image composed of a plurality of frame images F1 to F6 in which the motion of the subject is continuously captured; see FIG. 3A to FIG. (Step S1).
Next, among the plurality of frame images, based on a predetermined operation (for example, frame advance operation) of the operation input unit 8 by the user, a predetermined frame image (for example, used for adjusting the position of the index to be combined) When the first frame image F1 or the like is designated, the display control unit 7b displays the designated frame image on the display panel 7a (step S2; see FIG. 4).

Subsequently, for example, the index processing unit 6b reads out and acquires data of each default index (for example, the first to third reference lines L1 to L3) from a predetermined storage unit (for example, the memory 2). The display control unit 7b superimposes each index on a frame image (for example, the first frame image F1 or the like) and displays it on the display panel 7a (step S3).
Next, the index processing unit 6b determines whether or not an instruction to specify an index whose position is to be adjusted is input based on a predetermined operation of the operation input unit 8 by the user (step S4).

If it is determined in step S4 that an instruction to specify an index has been input (step S4; YES), the index processing unit 6b adjusts the position of the input index based on a predetermined operation of the operation input unit 8 by the user. In accordance with the instruction, the position of the index is adjusted in the frame image (step S5). Specifically, for example, in the case of a subject performing a golf swing, the index processing unit 6b adjusts the position of the first reference line L1 so as to pass through the waist portion and the club head portion of the subject.
Subsequently, the information acquisition unit 6c acquires information corresponding to each of the plurality of indexes, and the display control unit 7b displays information based on the acquired indexes as frame images (for example, the first frame image F1). To be displayed on the display panel 7a (step S6). Specifically, for example, in the case of a subject performing a golf swing, the information acquisition unit 6c calculates a first angle A1 formed by the first reference line L1 and a horizontal straight line of the image, and the first reference line. Acquired as information corresponding to L1.
If it is determined in step S4 that an instruction for specifying an index has not been input (step S4; NO), the process of step S5 is skipped, and the display control unit 7b displays the acquired information. It is superimposed on the frame image and displayed on the display panel 7a (step S6).

Next, the display control unit 7b determines whether or not a moving image playback instruction has been input based on a predetermined operation of the operation input unit 8 by the user (step S7).
Here, if it is determined that a moving image playback instruction has been input (step S7; YES), the display control unit 7b displays a plurality of frame images in a state where each index and information based on each index are displayed in a superimposed manner. Are reproduced at a predetermined reproduction frame rate and displayed on the display panel 7a (step S8; see FIGS. 5A to 5F).

On the other hand, if it is determined in step S7 that no reproduction instruction is input (step S7; NO), the image analysis unit 6 generates an analyzed moving image based on a predetermined operation of the operation input unit 8 by the user. It is determined whether or not an instruction has been input (step S9).
Here, if it is determined that an instruction for generating an analyzed moving image has not been input (step S9), the image analysis unit 6 returns the process to step S4, and executes the subsequent processes. In other words, for example, when an instruction to specify an index whose position is to be newly adjusted is input in step S4 (step S4; YES), the index processing unit 6b uses the operation input unit 8 by the user in step S5. The index position is adjusted in the frame image in accordance with the index position adjustment instruction input based on the predetermined operation. In step S6, the information acquisition unit 6c acquires information corresponding to the index whose position is newly adjusted. Thereafter, the display control unit 7b performs the processes of steps S7 and S8 in substantially the same manner as described above, and proceeds to step S9.
Each of the above processes is repeatedly executed until it is determined in step S9 that an instruction to generate an analyzed moving image has been input (step S9; YES).

If it is determined in step S9 that an instruction to generate an analyzed moving image has been input (step S9; YES), the image analysis unit 6 uses each of the plurality of frame images and each index (for example, first to first). Three reference lines L1 to L3) and information based on each index (for example, the first to third angles A1 to A3, etc.) are combined to generate an analyzed moving image composed of a plurality of combined frame images G1 to G6. Image data is generated (step S10).
Then, the image recording unit 5 acquires and records the image data of the analyzed moving image generated by the image analyzing unit 6 (step S11), and ends the moving image analysis process.

As described above, according to the imaging apparatus 100 of the present embodiment, information based on an index (for example, a reference line passing through a predetermined portion of the subject) for analyzing a specific motion of the subject set in the moving image. (For example, an angle formed by a reference line and a predetermined straight line) is acquired, and the index and the acquired information are displayed on the display panel 7a in association with the acquired moving image, so the index is simply displayed. Instead, the information corresponding to the index is displayed in association with the moving image, so that the viewer can easily objectively grasp the information based on the index. In particular, the information based on the index can be objectively and easily grasped by the viewer by expressing the information based on the index as a numerical value such as an angle formed by a reference line and a predetermined straight line.
Further, since the position of the index in the image is adjusted and information corresponding to the position-adjusted index is acquired, even when the position of the index in the image is adjusted to the user-desired position, Information based on the index can be appropriately acquired according to the index after the position adjustment. At this time, a user-desired index whose position should be adjusted can be easily specified based on a predetermined operation by the user.

In addition, since a plurality of indices and information corresponding to each index are displayed on the display panel 7a in association with each other, even when a plurality of indices are set for analyzing a specific motion of the subject, each index is supported. Information can be displayed in an easy-to-understand manner. That is, each of the plurality of indices can be represented using a corresponding color, and similarly, each piece of information based on the plurality of indices can be represented using a color substantially equal to the corresponding index.
In this way, the viewer can easily objectively grasp each piece of information based on the plurality of indices.

  In addition, when the information corresponding to the index is expressed using an angle formed by the reference line and a predetermined straight line, a predetermined color is added to the area corresponding to the angle and displayed on the display panel 7a. The object represented as the corresponding information can be clearly displayed, and the information based on the index can be easily grasped objectively by the viewer.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
Below, the modification of a moving image analysis process is demonstrated.
In addition, the modified example of the moving image analysis process is substantially the same as the moving image analysis process performed by the imaging apparatus 100 of the above-described embodiment except for the details described below, and detailed description thereof is omitted.

<Modification 1>
In the moving image analysis processing according to the first modification, moving image image data (see FIG. 6) including a plurality of frame images based on a predetermined time point in a specific operation of the subject is used as a processing target of the moving image analysis processing. ing.
FIG. 6 schematically illustrates one frame image Fn among a plurality of frame images constituting the moving image.

  That is, the image acquisition unit 6a records image data of a moving image composed of a plurality of frame images based on a predetermined point in a specific movement of the subject (for example, an impact at the moment when a ball is hit by a club head). The data is read from the unit 5 and acquired as a processing target of the moving image analysis process.

For example, the index processing unit 6b sets a fourth reference line L4 for analyzing the incident angle of the club head, a fifth reference line L5 for analyzing the ball launch angle, and the like. Specifically, for example, the index processing unit 6b is designated based on a predetermined operation of the operation input unit 8 by the user in any one of the plurality of frame images before the club head and the ball are in contact with each other. A straight line passing through the position of the club head and the position of the club head specified based on a predetermined operation of the operation input unit 8 by the user in any one of the frame images after the club head and the ball are in contact with each other. Set as the fourth reference line L4. Similarly, the index processing unit 6b is, for example, a predetermined one of the operation input unit 8 by the user in any one of the plurality of frame images before (or when contacting) the club head and the ball. The position of the ball specified based on the operation and the position of the ball specified based on a predetermined operation of the operation input unit 8 by the user in any one of the frame images after the club head and the ball are in contact with each other. A straight line passing through is set as the fifth reference line L5.
The method for setting the fourth reference line L4 and the fifth reference line L5 described above is an example and is not limited to this, and can be arbitrarily changed as appropriate.

  For example, the information acquisition unit 6c calculates a fourth angle A4 formed by the fourth reference line L4 and the horizontal straight line of the image, acquires the fourth angle A4 as information corresponding to the fourth reference line L4, and the fifth reference line L4. A fifth angle A5 formed by the line L5 and the straight line in the horizontal direction of the image is calculated and acquired as information corresponding to the fifth reference line L5.

The display control unit 7b superimposes each of the plurality of frame images, and each of the plurality of indexes corresponds to a corresponding color (for example, red for the fourth reference line L4, green for the fifth reference line L5, etc. ) To display on the display panel 7a. In addition, the display control unit 7b, for example, sets the fourth angle A4 to “R: **” in red (R) substantially equal to the fourth reference line L4, and sets the fifth angle A5 to the fifth reference line L5. Are displayed in a predetermined position on the display panel 7a in the form of “B: **” in blue (B) substantially equal to the above.
In addition, the display control unit 7b, as information based on a plurality of indices, corresponds to an angle (for example, fourth, fifth angles A4, A5, etc.) formed by a reference line and a predetermined straight line (in FIG. 6, A predetermined color may be added to the regions B4 and B5) indicated by dots to display them on the display panel 7a.

  Even in such a configuration, as in the above-described embodiment, instead of simply displaying an index, information corresponding to an index (for example, a reference line passing through a predetermined portion of the subject) (for example, a reference line and a predetermined value) By displaying the angle formed by the straight line in association with the moving image, the viewer can easily objectively grasp information based on the index.

<Modification 2>
In the moving image analysis process according to the second modification, the display control unit 7b displays other moving images on the display panel 7a side by side with the moving image to be processed in the moving image analysis process (see FIG. 7). .

Specifically, the display control unit 7b arranges the moving image to be processed in the moving image analysis process in the left region of the display area of the display panel 7a, and places the other moving image in the right region. A moving image (for example, a swinging motion of a professional golfer or a swinging motion of the user himself / herself) is arranged. FIG. 7 shows one frame image Fa among a plurality of frame images constituting a moving image to be processed by the moving image analysis process and one of a plurality of frame images constituting another moving image. The frame image Fb is schematically shown.
Then, for each moving image, the display control unit 7b displays each index (for example, the first to third reference lines L1 to L3) and information corresponding to the index (for example, the first to third angles A1 to A3).
