Description

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

Conventionally, a technique for acquiring a still image while shooting a moving image has been known.

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

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

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

On the other hand, for events where it is unpredictable when it will occur, such as lightning and observation of nocturnal animals, it is necessary to record moving images for a long 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, for example, as described in Patent Document 1, a frame that automatically captures an event (the degree of change in the captured image) is specified, and a candidate flag is added to the specified frame. It is conceivable to apply the technique.

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

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

FIG. 1 is a diagram showing the configuration of the photographing apparatus 10 of the present invention. The photographing device 10 is composed of an interchangeable lens 100 and a photographing device main body 200, and a subject image (optical image) is formed on the image pickup element 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 to and detached from each other 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 drive unit 140 drives the zoom lens 110 and the focus lens 120 forward and backward in response to a command from the CPU (Central Processing Unit) 240 to perform zoom (optical zoom) adjustment and focus adjustment. The zoom adjustment and the focus adjustment may be performed according to a zoom operation or a focus operation (zoom ring (not shown, rotation of the focus ring, etc.)) performed by the user, in addition to the zoom adjustment and the focus adjustment performed in response to a command from the CPU 240. Further, the lens driving unit 140 controls the aperture 130 in response 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 is input to the CPU 240. The interchangeable lens 100 has an optical axis L.

The image pickup device main body 200 includes an image sensor 210, an AFE 220 (AFE: Analog Front End), an A / D converter 230 (A / D: Analog to Digital), and a CPU 240. The image pickup device main body 200 may have a shutter (not shown) for blocking light transmitted through the image pickup device 210. The image pickup 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 aperture 130 is imaged on the light receiving surface of the image pickup element 210. It 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 the subject can be acquired based on the signals of each color. As the image pickup device 210, various photoelectric conversion elements such as CMOS (Complementary Metal-Oxide Semiconductor) and CCD (Charge-Coupled Device) can be used. The AFE 220 performs noise removal, amplification, and the like 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 shooting device 10 can set any of a still image shooting mode, a normal moving image shooting mode (first moving image shooting mode), and a still image extraction moving image shooting mode (second moving image shooting mode) as the shooting mode. The still image shooting mode and normal movie shooting mode are the same modes as a normal digital camera, and the still image extraction movie shooting mode has different shooting conditions from the normal movie shooting mode (still image extraction rather than watching the movie itself). Shoot a movie with shooting conditions that emphasizes. Specifically, in the still image extraction video shooting mode, at least one of the shutter speed, the autofocus speed, the autoexposure tracking speed, and the white balance tracking speed is set higher than that of the normal video shooting mode. And / or the frame rate is set higher than that of the normal moving image shooting mode. Further, the resolution and the frame rate are set to the maximum values that can be set by the photographing apparatus 10 (for example, 4,000 × 2,000 pixels, 30 frames / sec), and the color tone is also set on the premise of still image extraction. The upper limit of ISO sensitivity is also set higher than that of the normal movie shooting mode.

For example, the shutter speed is usually set to a value corresponding to the frame rate of the recorded video (1/30 seconds when the frame rate is 30 frames / sec) in the video shooting mode, but in the still image extraction video mode. It is set to be faster than the frame interval (for example, less than 1/30 second). In the normal movie shooting mode, the shutter speed is set to a value corresponding to the frame rate of the movie so that a smooth movie is played, but in this case, blurring may occur for a moving subject. For this reason, in the still image extraction movie shooting mode, the shutter speed is set to be faster than the normal movie shooting mode (faster than the frame interval), which allows you to extract high-quality still images with less blurring of the subject. Will be possible. Similarly, by increasing the upper limit of the ISO sensitivity, the shutter speed can be increased, and as a result, a still image with less blurring can be extracted. In addition, the autofocus speed, auto-exposure tracking speed, auto-white balance tracking speed, etc. are set faster than in the normal movie shooting mode, so there are many frames that are in focus on the subject and frames that are properly exposed. Can be obtained. By setting the frame rate to a high rate, the frame interval of the moving image becomes shorter, and the number of frames that can be extracted as a still image increases.

According to the above-mentioned still image extraction video shooting mode, the video can be stored and the frames constituting the video can be extracted as a still image, so that the user does not know when an event (natural phenomenon, accident, accident, etc.) will occur. It is possible to easily take a picture of a happening, etc., a picture of a subject whose state changes with the passage of time, or a picture of a moving subject in a momentary state. At this time, as will be described in detail later, the still image can be extracted not only at the timing in which the recording of the still image is instructed but also at other timings, so that the user can acquire the still image at a desired timing. Further, by setting shooting conditions suitable for still image extraction (shutter speed, resolution, frame rate, etc. described above), high-quality still images can be extracted.

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 normally stored in the folder 21. Further, the storage unit 260 can also automatically delete the moving image file stored in the normal folder 21 (when a specified capacity or time has elapsed). For example, after the shooting is completed, the user may be asked if the file should be deleted, and the storage unit 260 may delete the moving image file normally stored in the folder 21 in response to the user's deletion instruction. The normal folder 21 and the event folder 23 will be described in detail later. The storage unit 260 is composed of various optical magnetic recording media, a non-temporary recording medium such as a semiconductor memory, and a control circuit thereof, 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 photographing apparatus main body 200 can be used. In addition, information related to the program and various controls of the CPU 240 is stored.

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

FIG. 2 is a block diagram showing a configuration example of a function realized by the CPU 240 mounted on the photographing apparatus 10. The hardware-like structure of the CPU 240 that executes various controls is various processors as shown below. For various processors, the circuit configuration can be changed after manufacturing CPU (Central Processing Unit), FPGA (Field Programmable Gate Array), etc., which are general-purpose processors that execute software (programs) and act as various functional units. Programmable Logic Device (PLD), which is a processor, and a dedicated electric circuit, which is a processor having a circuit configuration specially designed to execute a specific process such as ASIC (Application Specific Integrated Circuit). Is done.

One processing unit may be composed of one of these various processors, or may be composed of 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, one processor is configured by a combination of one or more CPUs and software, as represented by a computer such as a client or a server. There is a form in which the processor acts as a plurality of functional parts. Secondly, as typified by System On Chip (SoC), there is a form of using a processor that realizes the functions of the entire system including a plurality of functional parts with one IC (Integrated Circuit) chip. be. As described above, the various functional units are configured by using one or more of the above-mentioned various processors as a hardware-like structure.

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

The shooting unit 11 shoots and acquires a moving image based on the normal moving image shooting mode (first moving image shooting mode) or the still image extraction moving image shooting mode (second moving image shooting mode). The photographing unit 11 is further composed of an interchangeable lens 100, an image sensor 210, an AFE 220, an A / D converter 230, and other devices necessary for photographing.

The moving image file generation unit 13 generates a plurality of moving image files from the moving image acquired by the shooting unit 11. Specifically, the moving image file generation unit 13 generates a plurality of moving image files at predetermined time intervals for the moving images taken by the shooting unit 11. For example, the moving image file generation unit generates a plurality of moving image files divided every 1 minute or every 2 minutes.

The event detection unit 15 detects an event frame including an event from a plurality of frames constituting the moving image. Specifically, the event detection unit 15 determines whether or not an event has been captured in the frame by performing image processing on the frame, and if it is determined that the frame has captured the event, sets an event flag in the frame (addition). do). The event detection unit 15 can detect the event captured by the frame by various methods. For example, the event detection unit 15 detects an event by detecting a change in the shooting scene in the frame. Specifically, the event detection unit 15 sets an event flag and sets an event frame as a frame in which the difference value between frames in the entire image or ROI (Region Of Interest) is equal to or higher 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 invaded the frame. The event detected by the event detection unit 15 can be specified in advance by the user. For example, the user specifies in advance the threshold value of the ROI of the image and the inter-frame difference value detected as an event in the ROI, and the event detection unit 15 sets an event when the inter-frame difference value in the ROI specified by the user is equal to or greater than the threshold value. It may be determined that it has been captured. Further, even if the user specifies a specific moving object (animal, person, etc.) in advance, the event detection unit 15 detects that the moving object specified by the user has invaded the frame, and determines that the event has been captured. good. Further, the user may specify a plurality of events in advance, and in this case, an 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 saved.

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

The control unit 19 controls the storage of the moving image file in the storage unit 260. Specifically, when the still image extraction video recording mode is selected, the control unit 19 puts an event video file containing an event frame among a plurality of video files in the event folder 23, and the event frame is not included. Save the video file in the normal folder 21. As another aspect, when the still image extraction moving image shooting mode is selected, the control unit 19 may also save the event moving image file in the event folder 23 and the normal folder 21.

FIG. 3 is a diagram showing an example of a storage configuration 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 saved in the event folder 23, the user may search in the event folder 23 when searching for a desired event frame, and can easily and quickly find the desired event frame. In the case of the moving image shooting mode for still image extraction, the event frame desired by the user is extracted as a still image. Further, since the event folder 23 does not require any special specifications and is a folder generated by a known technique, it has special specifications even when data communication with an external device is performed via a recording medium. The event folder 23 can be confirmed even in an external device that does not have the event folder 23. Further, the normal folder 21 and the event folder 23 may be provided as virtual folders.

A moving image file having no event frame is saved in the normal folder 21. Further, the moving image file acquired by the shooting unit 11 is temporarily stored in the normal folder 21, and then 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. You may save it. Further, the moving image file acquired by the shooting unit 11 is temporarily saved in the normal folder 21, and then the event moving image file in which the event is detected by the event detecting unit 15 is saved in the normal folder 21 by the control unit 19. You may copy and save it in the event folder 23 as it is.

The storage unit 260 may be composed of a single storage medium or a plurality of storage media. When the storage unit 260 is composed of a plurality of storage media, for example, the storage unit 260 is composed of a first storage medium and a second storage medium. 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 showing the relationship between the generation of a moving image file and the event detection. FIG. 4A shows the 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, and FIG. 4B shows a recording start process in the storage unit 260. 4 (C) shows the timing of closing processing of each moving image file, and FIG. 4 (D) shows the timing of 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 still image extraction moving image shooting mode, the moving image shooting is started, and at the same time, the recording start processing of the moving image file in the normal folder 21 is performed. Then, after a predetermined time has elapsed, the moving image file V1 is closed. Then, the event detection unit 15 detects the event for the moving image file V1. When the event detection unit 15 detects an 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, the moving image file (event moving image file) in which the event flag is set is described as "TRUE", and the moving image file in which the event flag is not 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 is generated, and the event frame 27, which is a frame that captures the event 25, is detected by the event detection unit 15. In this case, the event detection unit 15 sets an event flag and sets it as "TRUE".

FIG. 5 is a flowchart showing a shooting method (shooting process) performed by using the shooting device 10.

As the initialization of the shooting of the moving image file, the moving image shooting is started and the event detection is started (step S10). After that, the user inputs an instruction to start video recording via the operation unit 250 (step S11). Then, the moving image file shot by the shooting unit 11 is started to be recorded in the normal folder 21 (step S12). Next, the moving image file generation unit 13 determines whether or not there is an instruction to end the moving image recording (step S13), and closes the moving image file if there is an instruction to end the moving image recording (step S15). Further, the moving image file generation unit 13 determines whether or not the moving image recording has elapsed a predetermined time set in advance by the user (step S14), and closes the moving image file when the moving image recording has elapsed the predetermined time. (Step S15).

After that, the event detection unit 15 detects the event 25 in the moving image file (step S16), and when the event 25 is detected in the moving image file, the control unit 19 moves the moving image file to the event folder 23. And save (step S17). If 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. After that, it is determined whether or not there is an instruction to end the moving image shooting from the user via the operation unit 250 (step S18), and if there is an instruction to end, 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.

Each of the above configurations and functions can be appropriately realized by any hardware, software, or a combination of both. For example, for a program that causes a computer to perform the above-mentioned processing steps (processing procedure), a computer-readable recording medium (non-temporary recording medium) that records such a program, or a computer on which such a program can be installed. However, it is possible to apply the present invention.

As described above, in the present embodiment, the event video file having the event frame 27 among the plurality of video files in a predetermined period is stored in the event folder 23, so that the user can easily and quickly obtain a desired event. You can find the frame 27. Further, even when data communication is performed with an external device via a recording medium, the user can easily and quickly obtain a desired event frame without requiring special specifications for the external device of the data communication destination. You can find 27.

<Second embodiment>

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

FIG. 6 is a schematic diagram showing the relationship between the generation of a moving image file and the event detection. The parts already described in FIG. 4 are designated by the same reference numerals and the 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 (denoted as "TRUE" in the figure). After that, the event detection unit 15 corrects the event flag and sets the event flag for the video file V3 in which the event frame 27 is not detected, which was shot before the video file V4 in chronological order (in the figure, ". Notated as "TRUE"). Further, the event detection unit 15 corrects the event flag and sets the event flag for the video file V5 in which the event frame 27 is not detected, which was shot later in the time series of the video file V4 (in the figure, "TRUE"). Notation). As a result, after the event flag is corrected, the moving image file V3, the moving image file V4, and the moving image file V5 become the event moving image file. Then, the control unit 19 saves the moving image files V3, V4, and V5 in which the event flag is set in the event folder 23.

FIG. 7 is a flowchart showing a photographing method (imaging process) performed by using the photographing apparatus 10 of the present embodiment.
