Description

Imaging device, imaging method, and program

The present invention relates to a photographing device, a photographing method, and a program, and more particularly, to a technique for storing a moving image file.

2. Description of the Related Art A technique for acquiring a still image while capturing a moving image has been known.

For example, Patent Literature 1 proposes a technique for specifying only an image suitable for being output as a still image from a moving image at the time of shooting a moving image. Specifically, according to the technology described in Patent Document 1, it is determined that the degree of change of a captured image at the time of capturing a moving image is equal to or higher than a predetermined level (50%), and an image frame at that time is output as a still image output candidate. And a candidate flag is added. According to the technology described in Patent Document 1, when a still image output is instructed for a moving image file, each image frame to which a candidate flag is added is extracted and displayed as a list of still image output candidates. After that, the image frame arbitrarily selected from the list display is output as a still image.

In recent years, an imaging device having a moving image shooting mode for shooting a moving image for extracting a still image has been proposed in order to capture a momentary scene of a subject. For example, in the technique described in Patent Literature 2, the exposure time of one frame of a moving image for extracting a still image is set shorter than that of a normal moving image.

JP 2005-229236 A JP 2016-32303 A

Here, there is a need to extract a still image when an event intended by the user occurs while shooting a moving image. When photographing a still image of an event that can be predicted, the user predicts the occurrence of the event, issues a photographing instruction, and records a moving image or a still image for about several tens of seconds from the photographing instruction. Then, the user can obtain a desired still image capturing the occurrence of the event by checking the moving image or the still image. The event that can be predicted to some extent is, for example, the moment of hitting a ball with a tennis racket or the moment of shooting with soccer in sports.

On the other hand, it is necessary to record a moving image for a long time for an event such as lightning and observation of nocturnal animals, which cannot be predicted at any time. It takes a lot of effort and time to manually find a frame that captures a specific event from a long video. Therefore, in such a case, as described in Patent Literature 1, for example, a frame in which an event is captured automatically (the degree of change in a captured image) is specified, and a candidate flag is added to the specified frame. It is conceivable to apply technology.

However, such a technique of adding a candidate flag is not always standardized, and when data communication is performed with an external device via a recording medium, the candidate flag may not function well.

When extracting a frame to which a candidate flag is added, it is necessary to analyze all the frames again to extract a frame to which the candidate flag is added, and to extract a frame to which the candidate flag is added (event frame). And time is required for display.

Also, a technique of automatically detecting occurrence of an event by image processing or the like and adding a candidate flag as in the technique described in Patent Document 1 does not necessarily mean that the candidate flag can be added to a frame desired by the user.

Hereinafter, preferred embodiments of a photographing device, a photographing method, and a program according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a diagram showing a configuration of a photographing apparatus 10 according to the present invention. The photographing apparatus 10 includes an interchangeable lens 100 and a photographing apparatus main body 200, and forms a subject image (optical image) on the image sensor 210 by a photographing lens including a zoom lens 110 described later. The interchangeable lens 100 and the photographing apparatus main body 200 can be attached and detached via a mount (not shown).

The interchangeable lens 100 includes a zoom lens 110, a focus lens 120, a diaphragm 130, and a lens driving unit 140. The lens driving unit 140 performs zoom (optical zoom) adjustment and focus adjustment by driving the zoom lens 110 and the focus lens 120 forward and backward in response to a command from a CPU (Central Processing Unit) 240. The zoom adjustment and the focus adjustment may be performed in accordance with a zoom operation and a focus operation (a zoom ring, a rotation of a focus ring, and the like, not shown) performed by the user, in addition to performing the adjustment in response to a command from the CPU 240. Further, the lens driving unit 140 controls the aperture 130 according to a command from the CPU 240 to adjust the exposure. On the other hand, information such as the positions of the zoom lens 110 and the focus lens 120 and the degree of opening of the aperture 130 are input to the CPU 240. The interchangeable lens 100 has an optical axis L.

The image capturing apparatus main body 200 includes an image sensor 210, an AFE 220 (Analog Front End), an A / D converter 230 (A / D: Analog to Digital), and a CPU 240. The imaging device main body 200 may include a shutter (not shown) for blocking light transmitted to the imaging element 210. The imaging element 210 includes a light receiving surface in which a large number of light receiving elements are arranged in a matrix, and subject light transmitted through the zoom lens 110, the focus lens 120, and the diaphragm 130 is imaged on the light receiving surface of the imaging element 210, The light is converted into an electric signal by each light receiving element. An R (red), G (green), or B (blue) color filter is provided on the light receiving surface of the image sensor 210, and a color image of a subject can be obtained based on signals of each color. In addition, as the imaging element 210, various photoelectric conversion elements such as a complementary metal-oxide semiconductor (CMOS) and a charge-coupled device (CCD) can be used. The AFE 220 performs noise removal and amplification of the analog image signal output from the image sensor 210, and the A / D converter 230 converts the captured analog image signal into a digital image signal having a gradation width.

The photographing apparatus 10 can set any one of a still image photographing mode, a normal moving image photographing mode (first moving image photographing mode), and a still image extracting moving image photographing mode (second moving image photographing mode) as a photographing mode. The still image shooting mode and the normal moving image shooting mode are the same modes as a normal digital camera. In the moving image shooting mode for extracting a still image, a moving image having different shooting conditions from the normal moving image shooting mode (extracting a still image rather than watching the moving image itself) (Movies with shooting conditions with emphasis on). Specifically, in the moving image shooting mode for extracting a still image, at least one of a shutter speed, an autofocus speed, a tracking speed of an automatic exposure, and a tracking speed of a white balance is set to a high speed with respect to the normal moving image shooting mode, And / or the frame rate is set higher than the normal moving image shooting mode. Further, the resolution and the frame rate are set to the maximum values (for example, 4,000 × 2,000 pixels, 30 frames / sec) which can be set in the photographing apparatus 10, and the color tone is also set on the assumption that a still image is extracted. The upper limit of the ISO sensitivity is also set higher than the normal moving image shooting mode.

For example, the shutter speed is set to a value corresponding to the frame rate of the moving image to be recorded in the normal moving image shooting mode (1/30 second when the frame rate is 30 frames / second), but in the still image extracting moving image mode. It is set faster than the frame interval (for example, less than 1/30 second). In the normal moving image shooting mode, the shutter speed is set to a value corresponding to the frame rate of the moving image so that a smooth moving image is reproduced. In this case, a moving subject may be blurred. For this reason, in the moving image shooting mode for extracting still images, the shutter speed is set faster (faster than the frame interval) than in the normal moving image shooting mode, thereby extracting a high-quality still image with less subject blur. Becomes possible. Similarly, by increasing the upper limit of the ISO sensitivity, the shutter speed can be increased, and a still image with less blur can be extracted. Also, by setting the auto-focus speed, the auto-exposure tracking speed, and the auto-white balance tracking speed to be higher than those in the normal moving image shooting mode, the number of frames that are in focus on the subject and the frames that have an appropriate exposure are increased. Can be obtained. By setting the frame rate to a high rate, the frame interval between moving images is shortened, and the number of frames that can be extracted as a still image is increased.

According to the above-described still image extraction moving image shooting mode, since a moving image can be stored and frames constituting the moving image can be extracted as a still image, the user cannot know when an event (natural phenomenon, accident, (E.g., happening), a subject whose state changes over time, or a photograph of an instantaneous state of a moving subject can be easily taken. At this time, as will be described in detail later, since the still image can be extracted not only at the timing at which the recording of the still image was instructed but also at other timings, the user can obtain the still image at the desired timing. Further, a high-quality still image can be extracted by setting shooting conditions (such as the above-described shutter speed, resolution, and frame rate) suitable for extracting a still image.

The storage unit 260 includes a normal folder (second folder) 21 and an event folder (first folder) 23 (FIG. 3). The storage unit 260 can overwrite the moving image file stored in the normal folder 21. In addition, the storage unit 260 can automatically delete the moving image file stored in the normal folder 21 (when the specified capacity or time has elapsed). For example, the storage unit 260 may delete the moving image file stored in the normal folder 21 in response to the user's instruction to delete the file after the shooting is completed. The normal folder 21 and the event folder 23 will be described later in detail. The storage unit 260 includes various types of magneto-optical recording media, non-temporary recording media such as semiconductor memories, and control circuits therefor, and stores moving images, still images, still images extracted from moving images, and the like. As the recording medium, a type that can be attached to and detached from the imaging apparatus main body 200 can be used. Also, a program and information related to various controls of the CPU 240 are stored.

The monitor 270 includes a touch panel type liquid crystal display panel, and can display a moving image, a still image, a still image extracting frame, and the like. The monitor 270 can be arranged on the back side, the top side, or the like of the imaging device main body 200. The imaging device 10 may include a finder. The finder is composed of, for example, a liquid crystal display panel, a prism, a lens, and the like, and a user can visually recognize a moving image, a still image, a still image extracting frame, and the like through an eyepiece (not shown). As the finder, an "optical view finder (OVF)", an "electronic view finder (EVF)", or a hybrid view finder (HVF: Hybrid View Finder), which is a combination of these, is used. Can be used.

FIG. 2 is a block diagram illustrating a configuration example of a function realized by the CPU 240 mounted on the imaging device 10. The hardware structure of the CPU 240 for executing various controls is various processors as described below. For various processors, the circuit configuration can be changed after the production of CPUs (Central Processing Units), FPGAs (Field Programmable Gate Arrays), etc., which are general-purpose processors that act as various functional units by executing software (programs). Logic devices (Programmable Logic Devices: PLDs), ASICs (Application Specific Integrated Circuits), etc., including dedicated electrical circuits that are processors with a circuit configuration specifically designed to execute specific processing. It is.

One processing unit may be configured by one of these various processors, or configured by two or more processors of the same type or different types (for example, a plurality of FPGAs or a combination of a CPU and an FPGA). You may. Further, a plurality of functional units may be configured by one processor. As an example of configuring a plurality of functional units with one processor, first, as represented by a computer such as a client or a server, one processor is configured by a combination of one or more CPUs and software. There is a form in which a processor acts as a plurality of functional units. Second, as represented by a system-on-chip (System On Chip: SoC), a form using a processor that realizes the functions of the entire system including a plurality of functional units by one IC (Integrated Circuit) chip is used. is there. As described above, the various functional units are configured by using one or more of the above various processors as a hardware structure.

The CPU 240 includes a photographing unit 11, a moving image file generation unit 13, an event detection unit 15, and a control unit 19.

The imaging unit 11 captures and acquires a moving image based on a normal moving image shooting mode (first moving image shooting mode) or a still image extraction moving image shooting mode (second moving image shooting mode). Note that the imaging unit 11 is configured by other devices necessary for imaging, such as the interchangeable lens 100, the image sensor 210, the AFE 220, and the A / D converter 230.

The moving image file generating unit 13 generates a plurality of moving image files from the moving image acquired by the photographing unit 11. More specifically, the moving image file generating unit 13 generates a plurality of moving image files for a predetermined time set for the moving image captured by the image capturing unit 11. For example, the moving image file generation unit generates a plurality of moving image files divided every minute or every two minutes.

The event detection unit 15 detects an event frame including an event from a plurality of frames forming a moving image. Specifically, the event detection unit 15 determines whether an event is captured in the frame by performing image processing on the frame, and sets an event flag in the frame when determining that the frame captures the event (addition Do). The event detection unit 15 can detect an event captured by a frame by various methods. For example, the event detection unit 15 detects an event by detecting a change in a shooting scene in a frame. Specifically, the event detection unit 15 sets an event flag and sets an event flag as an event frame, assuming that an entire image or a frame in which a difference value between frames in a ROI (Region Of Interest) is equal to or greater than a certain value. Further, the event detection unit 15 may determine whether or not the frame has captured the event by detecting the moving object and determining that the moving object has entered the frame. The event detected by the event detection unit 15 can be specified in advance by the user. For example, the user previously specifies a ROI of an image and a threshold value of an inter-frame difference value to be detected as an event in the ROI, and the event detection unit 15 detects an event when the inter-frame difference value in the ROI specified by the user is equal to or larger than the threshold value. It may be determined that it has been caught. In addition, the user specifies a specific moving object (animal, person, or the like) in advance, and the event detection unit 15 detects that the moving object specified by the user has entered the frame, and determines that the event has been captured. Good. Further, the user may designate a plurality of events in advance. In this case, the event folder 23 may be created for each of the plurality of events designated by the user, and the event moving image file may be stored.

Further, the event detection unit 15 may receive an instruction from a user via the operation unit (instruction reception unit) 250 during shooting of a moving image, and detect an event based on the instruction. Specifically, when the user confirms the event, an instruction may be input via the operation unit 250, and an event flag may be set on a frame at the time when the instruction is given or near a frame where the instruction is given, to be an event frame. . In addition, the event detection unit 15 may detect an event based on a change in the posture of the imaging device 10 during imaging (for example, a change in the vertical and horizontal directions of the imaging device 10). In this case, the event detection unit 15 detects a change in the attitude of the imaging device 10 based on a signal from a sensor such as a gyro sensor provided in the imaging device 10.

The control unit 19 controls storage of the moving image file in the storage unit 260. Specifically, when the still image extraction moving image shooting mode is selected, the control unit 19 stores the event moving image file including the event frame among the plurality of moving image files in the event folder 23 and does not include the event frame. The moving image file is stored in the normal folder 21. As another mode, when the still image extraction moving image shooting mode is selected, the control unit 19 may store the event moving image file in the event folder 23 and the normal folder 21.

FIG. 3 is a diagram illustrating a storage configuration example of the storage unit 260. The storage unit 260 has a normal folder (second folder) 21 for storing a plurality of moving image files shot by the shooting unit 11, and an event folder (first folder) 23 for storing event moving image files. Since the event moving image file is moved and stored in the event folder 23, when searching for a desired event frame, the user only has to search the event folder 23, and can easily and quickly find the desired event frame. In the case of the still image extraction moving image shooting mode, an event frame desired by the user is extracted as a still image. Further, the event folder 23 is a folder generated by a known technique without any special specifications, and therefore has a special specification even when data communication with an external device via a recording medium is performed. The event folder 23 can be confirmed even in an external device that is not connected. Further, the normal folder 21 and the event folder 23 may be provided as virtual folders.

The normal folder 21 stores a moving image file having no event frame. The moving image file acquired by the photographing unit 11 is temporarily stored in the normal folder 21, and thereafter, the event moving image file in which the event is detected by the event detecting unit 15 is moved to the event folder 23 by the control unit 19. May be saved. Further, the moving image file acquired by the photographing unit 11 is temporarily stored in the normal folder 21, and thereafter, the event moving image file in which the event is detected by the event detecting unit 15 is stored in the normal folder 21 by the control unit 19. The data may be copied and stored in the event folder 23 as it is.

The storage unit 260 may be configured by one or more storage media. When the storage unit 260 includes a plurality of storage media, for example, the storage unit 260 includes a first storage medium and a second storage medium. Then, the event folder 23 is provided on the first storage medium, and the normal folder 21 is provided on the second storage medium.

<First embodiment>

FIG. 4 is a schematic diagram illustrating the relationship between the generation of a moving image file and event detection. 4A shows a timing at which a moving image is shot by the shooting unit 11 and a plurality of moving image files are generated by the moving image file generation unit 13. FIG. 4B shows a process of starting recording in the storage unit 260. 4 (C) shows the timing of the closing process of each moving image file, and FIG. 4 (D) shows the timing of the event detection performed by the event detection unit 15. .

In FIG. 4, moving image files V1 to V8 separated by a predetermined time are continuously photographed. In the moving image shooting mode for extracting a still image, shooting of a moving image is started, and at the same time, recording of a moving image file in the normal folder 21 is started. Thereafter, after a predetermined time has elapsed, the closing process of the moving image file V1 is performed. Then, the event detection unit 15 performs event detection on the moving image file V1. When detecting the event frame 27 including the event 25 in the moving image file, the event detecting unit 15 sets an event flag in the moving image file. In the figure, a moving image file with an event flag set (event moving image file) is described as “TRUE”, and a moving image file without an event flag set is described as “FALSE”.

In the moving image file V4, the event detection unit 15 detects the event frame 27 including the event 25. Specifically, during the shooting period of the moving image file V4, the event 25 occurs, and the event detection unit 15 detects an event frame 27 that is a frame capturing the event 25. In this case, the event detection unit 15 sets the event flag to “TRUE”.

FIG. 5 is a flowchart illustrating an imaging method (imaging step) performed using the imaging device 10.

As initialization of shooting of a moving image file, moving image shooting is started and event detection is started (step S10). Thereafter, a moving image recording start instruction is input from the user via the operation unit 250 (step S11). Then, the recording of the moving image file photographed by the photographing unit 11 into the normal folder 21 is started (step S12). Next, the moving image file generation unit 13 determines whether or not there is a moving image recording end instruction (Step S13), and closes the moving image file if there is a moving image recording end instruction (Step S15). In addition, the moving image file generation unit 13 determines whether or not the moving image recording has passed a predetermined time set in advance by the user (Step S14), and closes the moving image file if the moving image recording has passed the predetermined time. (Step S15).

Thereafter, the event detector 15 detects the event 25 in the moving image file (step S16). If the event 25 is detected in the moving image file, the controller 19 moves the moving image file to the event folder 23. And save (step S17). When the event detection unit 15 does not detect the event 25 in the moving image file, the moving image file is kept stored in the normal folder 21. Thereafter, it is determined whether or not there is an instruction from the user via the operation unit 250 to end the moving image shooting (step S18), and if there is an end instruction, the shooting unit 11 ends the moving image shooting. . On the other hand, if there is no instruction to end the moving image recording, the next moving image file is recorded in the normal folder 21.

The above-described configurations and functions can be appropriately realized by arbitrary hardware, software, or a combination of both. For example, a program that causes a computer to execute the above-described processing steps (processing procedure), a computer-readable recording medium (non-transitory recording medium) on which such a program is recorded, or a computer on which such a program can be installed However, the present invention can be applied.

As described above, in the present embodiment, the event moving image file having the event frame 27 among the plurality of moving image files for the predetermined period is stored in the event folder 23, so that the user can easily and quickly obtain the desired event. The frame 27 can be found. In addition, even when performing data communication with an external device via a recording medium, the user can easily and quickly obtain a desired event frame without requiring special specifications in the external device of the data communication destination. 27 can be found.

<Second embodiment>

Next, a second embodiment of the present invention will be described. In the present embodiment, a moving image file recorded immediately before an event moving image file, or a moving image file recorded immediately after an event moving image file, does not include the event frame 27, and is similar to an event moving image file. Move to folder 23 and save.

FIG. 6 is a schematic diagram illustrating the relationship between the generation of a moving image file and event detection. The parts already described in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted.

In the example shown in FIG. 6, the event frame 27 is detected in the moving image file V4. Then, the event detection unit 15 sets an event flag for the moving image file V4 (depicted as "TRUE" in the figure). After that, the event detection unit 15 also corrects the event flag and sets the event flag for the moving image file V3 that is photographed before the moving image file V4 in chronological order and for which the event frame 27 is not detected (in the figure, “ TRUE ").
