  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a hardware configuration of an imaging apparatus according to an embodiment of the present invention.
The imaging device 1 is configured as a digital camera, for example.

  The imaging apparatus 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an imaging unit 16, and an input unit 17. An output unit 18, a storage unit 19, a communication unit 20, and a drive 21.

  The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 19 to the RAM 13.

  The RAM 13 appropriately stores data necessary for the CPU 11 to execute various processes.

  The CPU 11, ROM 12, and RAM 13 are connected to each other via a bus 14. An input / output interface 15 is also connected to the bus 14. An imaging unit 16, an input unit 17, an output unit 18, a storage unit 19, a communication unit 20, and a drive 21 are connected to the input / output interface 15.

  Although not shown, the imaging unit 16 includes an optical lens unit and an image sensor.

The optical lens unit is configured by a lens that collects light, for example, a focus lens or a zoom lens, in order to photograph a subject.
The focus lens is a lens that forms a subject image on the light receiving surface of the image sensor. The zoom lens is a lens that freely changes the focal length within a certain range.
The optical lens unit is also provided with a peripheral circuit for adjusting setting parameters such as focus, exposure, and white balance as necessary.

The image sensor includes a photoelectric conversion element, AFE (Analog Front End), and the like.
The photoelectric conversion element is composed of, for example, a CMOS (Complementary Metal Oxide Semiconductor) type photoelectric conversion element or the like. A subject image is incident on the photoelectric conversion element from the optical lens unit. Therefore, the photoelectric conversion element photoelectrically converts (captures) the subject image, accumulates the image signal for a predetermined time, and sequentially supplies the accumulated image signal as an analog signal to the AFE.
The AFE performs various signal processing such as A / D (Analog / Digital) conversion processing on the analog image signal. Through various signal processing, a digital signal is generated and output as an output signal of the imaging unit 16.
Hereinafter, the output signal of the imaging unit 16 is referred to as “captured image data”. Data of the captured image is appropriately supplied to the CPU 11 or an image processing unit (not shown).

The input unit 17 includes various buttons and the like, and inputs various types of information according to user instruction operations.
The output unit 18 includes a display, a speaker, and the like, and outputs images and sounds.
The storage unit 19 is composed of a hard disk, a DRAM (Dynamic Random Access Memory), or the like, and stores various image data.
The communication unit 20 controls communication performed with other devices (not shown) via a network including the Internet.

  A removable medium 31 made of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately attached to the drive 21. The program read from the removable medium 31 by the drive 21 is installed in the storage unit 19 as necessary. The removable medium 31 can also store various data such as image data stored in the storage unit 19 in the same manner as the storage unit 19.

  In the imaging apparatus 1 configured as described above, when zooming and panning operations are performed during shooting, zooming and panning images are stepped in accordance with a moving image playback speed different from the actual shooting interval. It has a function capable of generating a time-lapse moving image with a change in the angle of view that changes to.

The principle of generating a time-lapse moving image generated in such an imaging apparatus 1 will be described.
The time-lapse moving image according to the present embodiment is a moving image in which the angle of view moves in a predetermined direction with time and changes so as to zoom.
The time-lapse movie of this embodiment does not change the angle of view at the time of shooting, and the angle of view changes when the movie is generated by using a movie in which a predetermined range is taken continuously (continuously in time). Generated using the processed image. The time-lapse moving image according to the present embodiment is generated corresponding to the change in the angle of view during interval shooting.
Here, “interval shooting” means shooting so that images are acquired intermittently at fixed intervals by shooting, that is, continuous for a total shooting time including a specified shooting interval or a non-shooting time. Intermittent shooting.

  Hereinafter, an example of interval shooting 1 in which the zoom is changed to the TELE side where the zoom magnification is increased and interval shooting 2 in which the zoom is changed to the WIDE side where the zoom magnification is reduced during the interval shooting will be described.

FIG. 2 is a diagram for explaining generation of a time-lapse moving image of interval shooting 1.
In interval shooting 1, as shown in FIG. 2A, seven captured images 101 to 107 are acquired at predetermined shooting intervals. Among the captured images 101 to 107, the captured image 107 is an image in which the zoom is switched from 1 to 2 times on the TELE side at the timing A before the image capturing, and the vicinity of the center of the imaging range is enlarged. With enlargement, the subject indicated by a circle in the figure is about twice as large.

In normal time-lapse moving image generation, each captured image is converted to a moving image at the current angle of view as a frame image (hereinafter referred to as “configuration frame image”) that constitutes the time-lapse moving image.
For this reason, when a normal time-lapse moving image is generated, the size of the subject does not change from the moving image start frame 201 to the frame 206 as shown in FIG. The size of is changed and played.

On the other hand, in the time-lapse moving image of the present embodiment, as shown in FIG. 2C, in the captured images 113 to 116 before (past) the captured image 117 in which the zoom has changed on the TELE side, gradually. The image area (broken line in the figure) of the captured images 113 to 116 is trimmed so that the angle of view changes by zooming to the TELE side, and an image adjusted to the same size as the captured images 111 and 112 is generated. Frame image.
The captured image candidate to be trimmed and the size to be trimmed in the captured image are determined in consideration of the zoom magnification, the zoom movement time, and the playback frame rate.
In this example, the changed zoom magnification is 1 to 2 times, the zoom movement time is 0.5 seconds, and the playback frame rate is 10 fps. Hereinafter, it is referred to as “the number of zoom movement frames”). Then, since the zoom magnification is changed from 1 to 2 times, the number of zoom movement frames is 5 and trimming is performed while reducing the trimming size in the captured images 113 to 116 by 1/5.

By setting the captured image to be trimmed in this way and the size to be trimmed in each captured image, as shown in FIG. 2D, each frame 211 to gradually expands at a speed corresponding to the zoom movement time. In 217, a time-lapse moving image in which the angle of view changes to the T (TELE) side is generated.
Therefore, in this example, a time-lapse moving image in which the angle of view changes in a natural manner is generated.

FIG. 3 is a diagram for explaining generation of a time-lapse moving image of interval shooting 2.
In the interval shooting 2, as shown in FIG. 3A, seven captured images 121 to 127 are acquired at a predetermined shooting interval. Among the captured images 121 to 127, the captured image 121 is an image in which the zoom is switched from 2 times to 1 time on the WIDE side at the timing B after the image capturing and the vicinity of the center of the image capturing range is reduced. With enlargement, the subject indicated by a circle in the figure is about ½ times larger.

In the generation of a normal time-lapse moving image, each captured image is converted into a moving image at the current angle of view as a constituent frame image constituting the time-lapse moving image.
Therefore, when a normal time-lapse moving image is generated, the size of the subject suddenly changes between the moving image start frame 221 and the frame 222 as shown in FIG. 3B, and then reaches the frame 227. The size of the subject does not change until

On the other hand, in the time-lapse moving image of the present embodiment, as shown in FIG. 3C, in the captured images 133 to 137 after (the future) the captured image 132 in which the zoom has changed on the WIDE side, gradually. The image area (broken line in the figure) of the captured images 132 to 135 is trimmed so that the angle of view changes by zooming to the WIDE side, and an image adjusted to the same size as the captured image 131 is generated, and the configuration frame image And
The captured image to be trimmed and the size to be trimmed in the captured image are determined in consideration of the zoom magnification, the zoom movement time, and the playback frame rate.
In this example, the changed zoom magnification is 2 to 1, the zoom movement time is 0.5 seconds, and the playback frame rate is 10 fps. Hereinafter, it is referred to as “the number of zoom movement frames”). Since the zoom magnification changes from 2 times to 1 time, the number of zoom movement frames is set to 5, and trimming is performed while increasing the trimming size in the captured images 132 to 135 by 1/5.

By setting the captured image to be trimmed in this way and the size to be trimmed in each captured image, as shown in FIG. 3D, each frame 231-1 is gradually reduced at a speed corresponding to the zoom movement time. In 237, a time-lapse moving image in which the angle of view changes to W (WIDE side) is generated.
Therefore, also in this example, a time-lapse moving image in which the angle of view changes in a natural manner is generated.

FIG. 4 is a functional block diagram illustrating a functional configuration for executing the time-lapse moving image generation process among the functional configurations of the imaging apparatus 1 as described above.
Time-lapse movie generation processing means that in a captured image obtained by performing interval shooting, the angle of view changed rapidly using an image cut out at a predetermined size and position from the captured image near the captured image where the shooting operation was performed. This refers to processing until a time-lapse movie that does not become such a movie is generated. In the present embodiment, in the time-lapse moving image generation process, a time-lapse moving image that gradually zooms is generated.

As shown in FIG. 4, the time-lapse moving image generation process is performed by the CPU 11 in the shooting period setting unit 51, the input operation detection unit 52, the interval shooting control unit 53, the image acquisition unit 54, and the moving image condition setting unit 55. The shooting operation specifying unit 56, the trimming processing unit 57, and the time-lapse moving image generating unit 58 function.
A captured image storage unit 71 and a time-lapse moving image storage unit 72 are set in one area of the storage unit 19.
The captured image storage unit 71 stores captured image data output from the imaging unit 16.
The time-lapse moving image storage unit 72 stores data of the generated time-lapse moving image.

  The shooting period setting unit 51 sets a shooting period for interval shooting in the imaging unit 16. Specifically, the shooting period setting unit 51 sets a shooting frame rate (first time interval).

  The input operation detection unit 52 detects an operation related to shooting (hereinafter referred to as “shooting operation”) such as an operation of zooming the input unit 17. The input operation detection unit 52 outputs the detection result to the interval shooting control unit 53.

The interval shooting control unit 53 controls the imaging unit 16 to perform interval shooting. In addition, the interval shooting control unit 53 receives the shooting operation detected by the input operation detection unit 52 and performs control to change the angle of view such as zoom.
Further, the interval shooting control unit 53 stores the captured image output from the imaging unit 16 in the captured image storage unit 71. The interval shooting control unit 53 saves an imaging operation and shooting conditions (EXIF (Exchangeable image file format) information) on the output captured image. Specifically, the interval shooting control unit 53 saves zoom magnification information such as a zoom level in the captured image.

  The image acquisition unit 54 acquires a captured image stored in the captured image storage unit 71.

  The moving picture condition setting unit 55 sets moving picture conditions such as a playback frame rate and a playback time of the time-lapse moving picture to be generated. Specifically, the moving image condition setting unit 55 sets moving image conditions such as a playback frame rate (second time interval).

The shooting operation specifying unit 56 specifies a captured image in which a shooting operation has been performed based on the fact that there has been an imaging operation stored in the captured image and shooting conditions. Further, the shooting operation specifying unit 56 specifies the content of the shooting operation such as the zoom magnification from information such as shooting conditions stored in the captured image.
In the case of the example of FIG. 2A, the shooting operation specifying unit 56 specifies the captured image after the zoom is changed to the TELE side where the zoom magnification is increased, and further, the zoom is 1 to 2 times. Identify that it has doubled.
In the case of the example of FIG. 3A, the photographing operation specifying unit 56 specifies the captured image before the zoom is changed to the WIDE side where the zoom magnification is reduced, and the zoom is doubled. It is specified that it has changed from 1 to 1.

The trimming processing unit 57 performs a trimming process based on the moving image condition set by the moving image condition setting unit 55 and the captured image specified by the shooting operation specifying unit 56.
In the trimming process, the zoom movement time required to move to the magnification is acquired from the changed zoom magnification, and the number of zoom movement frames corresponding to the zoom movement time is calculated from the reproduction frame rate. Then, in the trimming process, the angle of view is adjusted by cutting out the image area with a predetermined size in each corresponding captured image so that the zoom gradually changes with respect to the captured image group corresponding to the calculated frame group. Perform trimming. In the trimming process, the captured image to be trimmed and the size to be trimmed in the captured image are determined in consideration of the zoom magnification, the zoom movement time, and the playback frame rate.
As a result, in the trimming process, a constituent frame image that is a frame image constituting the time-lapse moving image is generated.
In the example of FIG. 2A, since the zoom is changed to the TELE side where the zoom magnification is enlarged, the captured image 117 after the zoom is changed to the TELE side is changed to the past captured image of the number of zoom movement frames. On the other hand, as shown in FIG. 2C, trimming is performed so that the image area is gradually narrowed up to the zoom magnification after the zoom is changed to generate a constituent frame image.
In the example of FIG. 3A, since the zoom is changed to the WIDE side where the zoom magnification is reduced, the future imaging of the zoom movement frame number from the captured image 131 before the zoom is changed to the WIDE side. As shown in FIG. 3C, the image is trimmed so as to gradually widen the image area up to the zoom magnification after the zoom is changed, thereby generating a configuration frame image.
By generating the configuration frame image in this manner, it is possible to generate a continuous time-lapse moving image without a sudden change in the angle of view.

The time-lapse moving image generation unit 58 generates a time-lapse moving image including the constituent frame images generated by the trimming processing unit 57 so that the moving image condition set by the moving image condition setting unit 55 is satisfied. In addition, the time-lapse moving image generation unit 58 outputs the generated time-lapse moving image and stores it in the time-lapse moving image storage unit 72.
As a result, in the case of using the captured images 101 to 107 obtained by interval shooting as shown in FIG. 2A, a time-lapse movie having a change in which the angle of view gradually increases as shown in FIG. Is generated. In addition, when the captured images 121 to 127 obtained by interval shooting as shown in FIG. 3A are used, a time-lapse movie having a change that gradually reduces the angle of view as shown in FIG. Generated.

FIG. 5 is a flowchart for explaining the flow of the time-lapse moving image generation process executed by the imaging apparatus 1 of FIG. 1 having the functional configuration of FIG.
The time-lapse moving image generation process is started by an operation for starting the time-lapse moving image generation process to the input unit 17 by the user.

In step S11, the interval shooting control unit 53 performs interval shooting. Specifically, the interval shooting control unit 53 performs interval shooting based on the shooting period set in advance by the shooting period setting unit 51. In the interval shooting, the interval shooting control unit 53 receives the shooting operation detected by the input operation detection unit 52 and performs control to change the angle of view such as zoom.
Thereafter, the interval shooting control unit 53 outputs the captured image output from the imaging unit 16 to the captured image storage unit 71. At that time, the interval shooting control unit 53 stores the captured image output from the imaging unit 16 in the captured image storage unit 71.
As a result, the captured image storage unit 71 stores captured images captured at intervals according to the setting by the shooting period setting unit 51.
Specifically, for example, when zooming to the TELE side in the final stage, captured images 101 to 107 as shown in FIG. Further, when zooming to the WIDE side in the initial stage, captured images 121 to 127 as shown in FIG.

  In step S12, the image acquisition unit 54 acquires a captured image. Specifically, the image acquisition unit 54 acquires a captured image stored in the captured image storage unit 71.

  In step S13, the moving image condition setting unit 55 sets moving image conditions such as a playback frame rate based on an input operation by a user, a default setting, and the like.

In step S <b> 14, the shooting operation specifying unit 56 specifies the captured image that has been shot and the shooting conditions.
In the case of the example of FIG. 2A, the shooting operation specifying unit 56 specifies the captured image 107 after the zoom is changed to the TELE side where the zoom magnification is increased, and further, the zoom is started from 1 ×. Identify that it has changed by a factor of two.
In the case of the example of FIG. 3A, the photographing operation specifying unit 56 specifies the captured image 121 before the zoom is changed to the WIDE side where the zoom magnification is reduced, and further, the zoom is 2 Identifies the change from double to one.

In step S15, the trimming processor 57 performs a trimming process. The trimming processing unit 57 determines the captured image to be trimmed and the size to be trimmed in the captured image in consideration of the zoom magnification, the zoom movement time, and the playback frame rate, and performs trimming under the determined conditions.
Specifically, in the case of the example of FIG. 2A, the trimming processing unit 57 has changed the zoom to the TELE side where the zoom magnification is increased, and therefore the trimming processing unit 57 has changed the zoom to the TELE side. As shown in FIG. 2C, the captured images 102 to 107 gradually narrow the image area from the captured image 107 to the zoom magnification after the zoom is changed with respect to the captured image in the past number of zoom movement frames. The captured images 112 to 117 corresponding to are trimmed to generate a configuration frame image.
In the example of FIG. 3A, the trimming processing unit 57 changes the zoom to the WIDE side where the zoom magnification is reduced, and thus the captured image 121 before the zoom is changed to the WIDE side. From the number of zoom movement frames to the future captured image, it corresponds to the captured images 121 to 125 so that the image area gradually increases as shown in FIG. 3C from the zoom magnification after the zoom is changed. The captured images 131 to 135 are trimmed to generate a configuration frame image.

In step S16, the time-lapse moving image generating unit 58 generates a time-lapse moving image. Specifically, a time-lapse moving image including the constituent frame images generated by the trimming processing unit 57 is generated so as to satisfy the moving image condition set by the moving image condition setting unit 55.
Specifically, the time-lapse moving image generating unit 58 gradually increases the angle of view as shown in FIG. 2D when using the captured images 101 to 107 obtained by interval shooting as shown in FIG. Generate time-lapse movies with changes that expand.
Further, when using the captured images 121 to 127 obtained by interval shooting as shown in FIG. 3A, the time-lapse moving image generation unit 58 gradually reduces the angle of view as shown in FIG. Generate a time-lapse movie with various changes.
Therefore, the imaging apparatus 1 can generate a continuous time-lapse moving image without a sudden change in the angle of view.

The imaging device 1 configured as described above includes the imaging unit 16, the interval shooting control unit 53, the input operation detection unit 52, the shooting operation specifying unit 56, and the trimming processing unit 57.
The interval shooting control unit 53 controls the image pickup unit 16 to take images continuously in time at the first time interval (shooting frame rate).
The input operation detection unit 52 detects a change in the angle of view when the interval shooting control unit 53 is capturing an image.
The shooting operation specifying unit 56 has a second time interval (reproduction frame rate) different from the first time interval (shooting frame rate) among a plurality of still images obtained as a result of being imaged by the interval shooting control unit 53. Specify still images to be played sequentially.
The trimming processing unit 57 trims the still image specified by the shooting operation specifying unit 56 in accordance with the change in the angle of view detected by the input operation detecting unit 52.
Thereby, in the imaging device 1, in order to trim the still image specified by the shooting operation specifying unit 56 according to the change in the angle of view detected by the input operation detecting unit 52, a time-lapse moving image rich in change is displayed. Can be generated.

The input operation detection unit 52 detects a shooting operation as an instruction to change the angle of view with respect to the apparatus.
As a result, the imaging device 1 generates a time-lapse movie that reflects the intention of the explicit user in order to change the angle of view, for example, to detect a shooting operation such as a zoom operation or a direction change operation of the imaging device 1. can do.

In addition, the trimming processing unit 57 trims a plurality of still images according to the change in the angle of view detected by the detection unit and the second time interval.
Thereby, in the imaging device 1, it is possible to generate a time-lapse movie in which the change is not abrupt and the change is natural.

The trimming processing unit 57 trims a still image according to a change in the angle of view that translates within the angle of view.
At this time, the constituent frame image is generated not by using the entire image but leaving an area that can be compensated for panning and moving. With this configuration, even if there is only a captured image in which the angle of view has changed rapidly due to panning, it is possible to generate a configuration frame image that can compensate for the movement in the surplus area.
Thereby, in the imaging device 1, it is possible to generate a time-lapse moving image that is rich in changes such as panning gradually.

In addition, the trimming processing unit 57 trims a still image in accordance with the change in the angle of view that changes the size of the frame itself.
As a result, the imaging apparatus 1 can generate a time-lapse moving image rich in changes such as gradually zooming.

In addition, the imaging apparatus 1 includes a time-lapse moving image generation unit 58 that generates a moving image.
Thereby, in the imaging device 1, it can perform consistently from imaging | photography of the image used for the production | generation of a time-lapse moving image to the production | generation of a moving image with an own apparatus.

May be.

In the embodiment described above, the trimming is automatically performed using only the change in the angle of view of the imaging apparatus 1 as a trigger without considering the subject, but the present invention is not limited thereto. For example, a main subject or a specified specific subject can be detected, and a trimming frame or a cutout region can be set so that the subject is included.
Specifically, it further includes detection means for detecting a predetermined subject image.
In addition, the trimming processing unit 57 performs trimming so that a predetermined subject image detected by the detection unit is included.
As a result, the imaging apparatus 1 can generate a time-lapse moving image that follows the subject, and thus can generate a time-lapse moving image rich in change.

  In the above-described embodiment, the captured image to be trimmed is determined in consideration of the real time when the angle of view is changed. However, the present invention is not limited to this. For example, in consideration of a change in the entire time-lapse moving image, when the change in the whole is fast, the determination may be made earlier. The same applies to the size to be trimmed.
