  However, in the above-described conventional configuration, after all shooting is completed, a plurality of still image data is combined and converted into one moving image data, so that the moving image data can be viewed after the shooting is completed. There is a problem that it takes time. In addition, since moving image data is generated from a captured still image, there is a problem that a memory such as a RAM or other storage medium for storing a large amount of still image files is required in an intermediate stage.

  In order to solve the above-described problem, an information processing apparatus according to one embodiment of the present invention includes an information processing apparatus including a camera that captures a still image and a moving image encoder that generates one moving image file from the plurality of captured still images. Each time the camera captures an image, the image data for one frame is acquired from the camera, the image data is converted into moving image data for one or more frames, and the moving image data is converted into a moving image. An encoder control means for causing the moving image encoder to execute processing to be added to a file is provided.

Then, the moving image encoder is caused to execute the process of adding the moving image data to the moving image file.

  According to one embodiment of the present invention, the time required for generating a moving image after capturing a still image, which has been necessary in the past, is not necessary.

Embodiment 1
Hereinafter, embodiments of the present invention will be described in detail.

(Configuration of information processing apparatus 10)
First, based on FIG. 1, the structure of the information processing apparatus 10 which concerns on this embodiment is demonstrated. FIG. 1 is a block diagram illustrating an example of a schematic configuration of an information processing apparatus 10 according to the first embodiment of the present invention. The information processing apparatus 10 captures a still image and supplies the captured still images to the moving image encoder 4 to generate a moving image.

  In the present embodiment, a case will be described in which the information processing apparatus 10 is used for time-lapse shooting for capturing a still image for generating a moving image. The information processing device 10 may be any device that has an imaging function, and may be a camera, or may be a mobile communication terminal such as a mobile phone, a tablet, or a smartphone that has a camera function. The “imaging” includes not only taking a picture with the camera 1 but also acquiring a still image by scanning an image using a scanner device or the like. That is, the information processing apparatus 10 may be a device such as a scanner. The term “frame” is also called “frame” and is used to indicate one unit of moving image data constituting a moving image file. “Time-lapse photography” is one of the techniques for generating a moving image file, and a still image acquired by imaging an imaging target is used as imaging data corresponding to one frame of the moving image file. It is done.

  In one embodiment of the present invention, the information processing apparatus 10 includes a camera (imaging means) 1, an operation input unit 2, a moving image generation control unit 3, a moving image encoder 4, a display control unit 5, a display unit 6, and a storage unit 7. ing.

  The camera 1 is a digital camera, and is a camera module that images an object to be imaged using a CCD sensor, a CMOS sensor, or the like. A camera view image that is an image optically input through the camera 1 and imaging data obtained by imaging are output to the display control unit 5. Here, “imaging data” is captured still image data (still image data). Note that the captured still image is not limited to a two-dimensional image, and may be a three-dimensional image. When the still image is a three-dimensional image, a moving image of the three-dimensional image can also be generated.

  The operation input unit 2 is for a user to input various settings and instructions to the information processing apparatus 10, and includes a power switch, a shutter, and an imaging mode (time-lapse shooting mode, normal shooting mode, and video). Mode switching buttons). The operation input unit 2 can be realized in various forms. For example, a part or all of the above settings and instructions may be input by a touch operation on the display screen by superimposing a touch panel on the display screen of the display unit 6. Further, the information processing apparatus 10 may be provided with a voice analysis function to enable voice operation input.

  The moving image generation control unit 3 performs control for generating a moving image from a still image captured by time-lapse shooting. The moving image generation control unit 3 includes a frame information calculation unit 31 and a moving image encoder control unit (encoder control means) 32. The moving image generation control unit 3 repeatedly performs the processing described below until the imaging of a series of still images for generating a moving image is completed.

  The frame information calculation unit 31 of the moving image generation control unit 3 uses a frame information setting 71 such as a frame rate (FPS) of the moving image set by the user to determine the frame corresponding to the still image at the time of reproducing the moving image. A frame display time (time stamp) Δt (frame information), which is information defining the display time, is calculated. The frame display time Δt is information associated with each still image, and each moving image for one frame generated by supplying each imaging data to the moving image encoder 4 is displayed when the moving image is reproduced. Specifies the length of time to be played. For example, when the user sets the moving image to be played back at a frame rate of 25 frames per second (25 fps), the frame information calculation unit 31 calculates the frame display time Δt as 40 msec (1000 msec). / 25 fpm = 40 msec). The calculated frame display time Δt is sent to the moving image encoder control unit 32. Note that the frame information that can be input by the user is not limited to the frame rate, and may include, for example, the total number of still images to be captured and information for specifying each moving image file 72 stored in the storage unit 7. . Further, a different frame display time Δt may be associated with each captured still image.

  Each time the camera 1 captures an image, the moving image encoder control unit 32 acquires image data for one frame from the camera 1, converts the image data into moving image data for one or a plurality of frames, and the moving image data Is added to the moving image file 72, and the moving image encoder 4 is caused to execute. In addition, the moving image encoder control unit 32 causes the moving image encoder 4 to generate a moving image file 72 in response to an operation for starting capturing a still image for generating a moving image. The moving image encoder control unit 32 supplies the captured still image directly to the moving image encoder 4 and adds it to the moving image file 72 every time one still image is captured. That is, the moving image encoder control unit 32 supplies the moving image data to the moving image file 72 as moving image data by supplying the moving image encoder 4 without storing the captured image data in a storage device such as the storage unit 7.

  Further, the moving image encoder control unit 32 supplies the frame display time Δt together with the still image to the moving image encoder 4 when the shutter operation is input in the state where the camera 1 is set to the time-lapse shooting mode. A moving image that is displayed for a time specified by the frame information is added to the moving image file 72. Note that the timing for generating the moving image file 72 is not limited to this. Then, the image data of the still image at the moment when the shutter operation is input is acquired from the camera 1, the frame display time Δt is acquired from the frame information calculation unit 31, and both are supplied to the moving image encoder 4.

  The moving image encoder 4 generates a moving image file 72 in the storage unit 7 in response to the shutter operation. Further, every time one still image is captured, the moving image encoder 4 acquires the captured still image and the frame display time Δt corresponding to the still image from the moving image encoder control unit 32. Then, the captured still image is encoded, and a moving image for one or a plurality of frames constituting the moving image is generated and added to the moving image file 72. At this time, the moving image encoder 4 adds the moving image for each frame to the moving image file 72 so that the moving image is displayed over the time defined by the frame display time Δt when reproduced. That is, the moving image encoder 4 performs encoding for generating a moving image from a still image captured by the camera 1, and adds the generated moving image to the moving image file 72 to form a moving image (MUX). It also functions as a device.

  The display control unit 5 displays a camera view image output from the camera 1, various buttons / icons or a keyboard display for assisting an input by a touch operation by the user, a captured still image, and a generated moving image (moving image). The display unit 6 is controlled to display.

  The display unit 6 is a flat panel display such as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), or an organic EL (Organic LED). is there. As described above, a touch panel may be superimposed on the display screen of the display unit 6, and in this case, the display unit 6 in the display state also has a function as an operation input unit that receives a user's operation input. The display unit 10 is convenient for confirming the captured image and is preferably mounted, but is not an essential component of the information processing apparatus 10.

  The storage unit 7 is a memory that stores various settings input by the user, such as the frame information setting 71, and the moving image file 72 generated by the moving image encoder 4. For example, the storage unit 7 may be a storage medium such as a flash memory, a RAM, or an SD card.

  According to the information processing apparatus 10 having the above-described configuration, a moving image file can be generated in a short time from the end of imaging of a series of still images for generating a moving image file. In addition, a RAM such as a RAM for storing a large amount of still image files that have been stored in an intermediate stage or a memory such as another storage medium becomes unnecessary. Therefore, memory reduction can be realized.

  Here, although an example in which the still image for generating the moving image is shot using the camera 1 has been described, the information processing apparatus 10 is not limited to this. That is, the information processing apparatus 10 may generate a moving image from an arbitrary still image that can be used as each frame of the moving image. For example, a configuration including a scanner device or the like instead of the camera 1 or in addition to the camera 1 may be employed. In such a case, a still image captured by pressing a scan start button that is an instruction to start capturing a still image is used to generate a moving image. Further, for example, image data may be read from a camera or scanner device wired or wirelessly connected to the information processing apparatus 10 to generate a moving image. In this case, by configuring so that the shutter operation, the operation of the scan start button, and the like are also transmitted to the information processing apparatus 10, it is possible to realize a function equivalent to that of the information processing apparatus 10 of the present embodiment.

  Next, a flow of processing for performing time-lapse shooting using the information processing apparatus 10 and generating a moving image will be described with reference to FIG. FIG. 2 is a flowchart illustrating an exemplary flow of a moving image generation process performed by the information processing apparatus 10 illustrated in FIG.

  When the time-lapse shooting mode is selected by the user, the information processing apparatus 10 starts a process of generating a moving image from imaging data acquired by imaging to be started. Information for specifying the moving image frame rate (FPS), the total number of still images to be captured, and each moving image file 72 stored in the storage unit 7 by screen display on the display unit 6 or the like. To set the frame information, and the set FPS value is acquired (S1). Note that a setting request to the user is not essential, and an FPS value set by default may be acquired. However, it is preferable that the user can set the FPS value so that a moving image intended by the user can be generated. The FPS input by the user is stored in the frame information setting 71. The frame information calculation unit 31 calculates the frame display time Δt (frame information) based on the FPS value stored in the frame information setting 71 (S2).

  Next, in S3, the moving image encoder control unit 32 starts the moving image encoder 4 (START) and instructs to generate a moving image file. Thereby, in S <b> 4, the activated moving image encoder 4 newly generates a moving image file 72 in the storage unit 7. Note that a new moving image file 72 may be generated when the moving image generated using the first still image is stored in the storage unit 7.

  In S <b> 5, the camera 1 outputs the camera view image to the display control unit 5 and starts displaying the camera view image on the display unit 6. The user adjusts the captured still image to have a desired angle of view and composition by setting the posture of the information processing apparatus 10 and the optical system (such as a lens) while referring to the camera view image. can do.

  Next, when an operation for instructing imaging (shutter pressing) is input (YES in S6), the moving image encoder control unit 32 captures imaging data at the moment when the shutter is pressed (the same still image data as the camera view image). Then, the frame display time Δt calculated in S2 is supplied to the moving image encoder 4 (S7). The moving image encoder 4 encodes the supplied imaging data, generates a moving image for one frame constituting the moving image, and adds it to the moving image file 72. On the other hand, when there is no input of an operation for instructing imaging (shutter pressing) (NO in S6), the following processing of S8 is performed.

  If the time-lapse shooting has not been completed (NO in S8), the process returns to S5 and the imaging is continued. That is, the moving image generation control unit 3 repeats the processes of S5 to S7 until the series of still images for moving image generation is completed.

  When the time-lapse shooting is finished (YES in S8), the moving image encoder control unit 32 stops (STOP) the moving image encoder 4 in S9. Note that the time-lapse shooting may be determined to end when a predetermined end operation is performed. Further, for example, for each imaging, a display asking whether or not the user has ended may be performed, and it may be determined that the display is ended when an input operation is performed to end the display. Alternatively, it may be determined that shooting has been completed when shooting of a still number of still images set in advance as frame information by the user has ended. In step S10, the moving image file 72 is closed, and the generation of the moving image ends.

  Next, processing for generating a moving image from a still image captured by the information processing apparatus 10 will be described with reference to FIG. Here, the state from when the octopus comes out from the cocoon to the time when the smear is spouted will be described by taking as an example the case where a moving image is generated from the captured still images of six frames. In addition, although a case where the frame display time Δt (frame information) is constant (40 msec) in a series of imaging for generating a moving image will be described as an example, the present invention is not limited to this. The frame information can be arbitrarily set according to the moving image to be generated, and a different frame display time Δt can be associated with each captured still image.

  FIGS. 3A and 3B are explanatory diagrams for specifically explaining an example of the moving image generation process. FIG. 3A illustrates a case where the second still image P2 is captured, and FIG. 3B illustrates a case where the third still image P3 is captured. (C) shows an example of processing in each case where the sixth still image P6 is taken.

  In FIGS. 3A to 3C, an arrow indicating the passage of time when imaging is shown on the leftmost portion. The timing of acquiring a still image, that is, the timing of pressing the shutter is arbitrary, and the interval between each shooting may not be constant.

  A rectangle representing the moving image encoder 4 and a left-to-right arrow passing through the rectangle schematically represent a process of generating a moving image by encoding a still image (camera view image). That is, the camera view image drawn on the left side is supplied to the moving image encoder 4 to generate a moving image, and the moving image as a result added to the moving image file 72 is drawn on the right side of the moving image encoder 4.

  In FIG. 3A, first, when the first shutter pressing is performed by the camera 1, a still image P1 of the first camera view is acquired. The still image P1 is supplied from the moving image encoder control unit 32 to the moving image encoder 4 together with the frame display time Δt = 40 msec, and a moving image V1 having a display time of 40 msec is generated. The moving image V1 is stored in the moving image file 72. Added. Next, when a second shutter press is performed by the camera 1 after a while, a still image P2 of the second camera view is acquired. The still image P2 is supplied from the moving image encoder control unit 32 to the moving image encoder 4 together with the frame display time Δt = 40 msec, and a moving image V2 having a display time of 40 msec is generated. The moving image encoder 4 adds the moving image V2 to the moving image file 72. As a result, the moving image file 72 includes a moving image V1 and a moving image V2, and becomes a moving image having a total display time of 80 msec.

  Next, in FIG. 3B, when the third shutter pressing is performed, a still image P3 of the third camera view is acquired. A moving image V3 generated from the still image P3 is generated, and the moving image encoder 4 adds the moving image V3 to the moving image file 72. As a result, the total display time of the moving image file 72 is a moving image of 120 msec.

  Similarly, until a still image P6 of the sixth camera view for which a series of still images for capturing a moving image has been captured is repeatedly captured, as shown in FIG. A moving image file 72 having a total time of 240 msec including V1 to V6 is completed.

  In the rightmost part of FIG. 3, an arrow indicating the length of time displayed when the moving image file 72 is reproduced is shown. The length of this arrow is shown in the leftmost part of FIG. It is independent of the length of the arrow indicating the passage of time.

[Embodiment 2]
The following will describe another embodiment of the present invention. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

  First, the configuration of the information processing apparatus 20 will be described with reference to FIG. FIG. 4 is a block diagram illustrating an example of a schematic configuration of the information processing apparatus 20 according to the second embodiment. The information processing apparatus 20 according to the present embodiment is further provided with a still image data buffer (buffer storage unit) 8 and a buffer control unit (buffer control unit) 33, and the information processing apparatus 10 according to the first embodiment described above. Is different.

  The still image data buffer (buffer storage unit) 8 stores image data from the camera 1 for one frame. The buffer control unit 33 updates the image data stored in the still image data buffer 8 every time the camera 1 captures an image. The still image data buffer 8 is normally a double buffer so that image data can be stored and retrieved smoothly. In addition, when the image data stored in the still image data buffer 8 is updated to the image data newly acquired from the camera 1, the buffer control unit 33 stores the image data stored in the still image data buffer 8 in the still image data buffer 8 with respect to the moving image encoder control unit 32. Notifies that the stored imaging data has been updated. Upon receiving this notification, the moving image encoder control unit 32 supplies the image data for one frame stored in the still image data buffer 8 and the frame display time Δt to the moving image encoder 4.

  In the information processing apparatus 10 according to the first embodiment, when an operation for instructing imaging (shutter pressing) is input, the moving image encoder control unit 32 acquires a still image obtained from the camera 1 at the moment when the shutter is pressed. And the frame display time Δt are supplied to the moving image encoder 4. In contrast, when the information processing apparatus 20 according to the present embodiment receives an operation for instructing imaging (shutter pressing), the buffer control unit 33 displays a still image for one frame at the moment when the shutter is pressed. Obtained from the camera 1, the image data of the still image is temporarily stored in the still image data buffer 8. At this time, if the captured image data is already stored in the still image data buffer 8, the buffer control unit 33 captures the still image newly acquired from the camera 1 as the captured data to be stored in the still image data buffer 8. Update to data. That is, the buffer control unit 33 overwrites and saves the image data newly acquired from the camera 1 in the still image data buffer 8.

  As described above, the information processing device 20 stores the still image data buffer 8 that stores a still image for one frame, and the buffer that updates the imaging data stored in the still image data buffer 8 every time the camera 1 captures an image. And a control unit 33. The moving image encoder control unit 32 acquires the image data for one frame from the still image data buffer 8 and updates the frame display time from the frame information calculation unit 31 every time the image data in the still image data buffer 8 is updated. Δt is acquired, and both are supplied to the moving image encoder 4. This eliminates the need for a memory such as a RAM or other storage medium for storing a large amount of still image files that have been stored in the intermediate stage, and can reduce the memory.

[Embodiment 3]
The following will describe still another embodiment of the present invention. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

  In order to generate a moving image from a plurality of still images taken by time-lapse shooting, when a large number of still images are required to be captured, a series of imaging may be interrupted.

  Therefore, in the information processing apparatus 10 according to the second embodiment of the present invention, in addition to the FPS value, information for specifying each moving image file 72 stored in the storage unit 7 is input by the user. Thereby, it is possible to specify to which moving image file 72 a moving image generated from a still image to be captured is added.

  That is, when a plurality of unfinished moving image files 72 (for example, moving image file 72a and moving image file 72b) (not shown) are stored in the storage unit 7, the moving image encoder control unit 32 selects the moving image file 72a (or moving image file 72a). Information specifying the file 72b) is supplied to the moving image encoder 4 together with the captured still image. Thereby, a moving image generated from a still image to be captured can be added to a desired moving image file 72.

[Example of software implementation]
The control blocks of the information processing apparatuses 10 and 20 (in particular, the frame information calculation unit 31, the moving image encoder control unit 32, and the buffer control unit 33 of the moving image generation control unit 3) are formed in an integrated circuit (IC chip) or the like. It may be realized by a logic circuit (hardware), or may be realized by software using a CPU (Central Processing Unit).

  In the latter case, the information processing apparatuses 10 and 20 include a CPU that executes instructions of a program that is software that realizes each function, and a ROM (Read that records the above program and various data so that the computer (or CPU) can read them. Only Memory) or a storage device (these are referred to as “recording media”), a RAM (Random Access Memory) for expanding the program, and the like. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The program may be supplied to the computer via an arbitrary transmission medium (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.

[Summary]
The information processing apparatuses 10 and 20 according to the first aspect of the present invention are information processing apparatuses including a camera 1 that captures still images and a moving image encoder 4 that generates one moving image file 72 from a plurality of captured still images.

Each time, the moving image encoder may acquire the imaging data for one frame from the buffer storage unit.

  According to the above configuration, the imaging data stored in the buffer storage unit that stores the imaging data for one frame is updated each time the camera takes an image, and the imaging data for one frame is acquired from the buffer storage unit. Let As a result, it is sufficient if there is a memory for temporarily storing image data for one frame, and it is not necessary to store a large amount of still image files, which is conventionally performed at an intermediate stage. Therefore, the required memory can be reduced.
