Description

  The present invention relates to an imaging apparatus, a control method thereof, and a program.

  Some imaging devices, such as digital cameras, use still images with special effects such as effects taken with a fisheye lens, diorama effects that blur the top and bottom of the image, and soft focus effects that moderately blur the image. Some have a function to shoot. In addition, an imaging apparatus having a function of shooting a moving image to which such special effects are added by image processing has been proposed (Patent Document 1).

  In moving image shooting, a moving subject is often shot. Therefore, if shooting starts after receiving a moving image shooting start instruction by a release switch, there is a possibility that the intended moment will be missed. A so-called pre-REC-capable camera device has been proposed that records a moving image for a predetermined time (hereinafter also referred to as a “pre-REC period”) before a moving image shooting start instruction so as not to miss such an intended moment. (Patent Document 2).

JP 2006-340070 A JP 2006-80809 A

  There is a case where a special effect to be added to the moving image is not decided at the start of the moving image recording period. For example, in order to determine a special effect suitable for a subject, it is conceivable to determine a special effect to be added to a moving image at the timing of a moving image shooting start instruction, not during framing where the subject is not stable. When such a determination timing and the pre-REC are combined, a moving image is recorded in the pre-REC period, but a special effect is not determined. Therefore, a special effect cannot be added at least in real time to a moving image shot during the pre-REC period. However, conventionally, there has been no special proposal that takes into consideration the situation in which a special effect cannot be added in real time to a part of a captured moving image.

  The present invention has been made in view of such a situation, and an object thereof is to provide a moving image processing technique adapted to a situation where a special effect cannot be added in real time to a part of a photographed moving image.

  In order to solve the above-described problems, the present invention provides a photographing unit for photographing a moving image, a first moving image photographed by the photographing unit in a first period, and a second period following the first period. Image processing means for adding a special effect to the second moving image shot by the shooting means; and displaying the first moving image before the special effect is added in the first period; Display means for displaying the second moving image to which the special effect is added in a period of 2, and recording means for recording the first moving image and the second moving image to which the special effect is added; An imaging device is provided.

  Other features of the present invention will become more apparent from the accompanying drawings and the following description of the preferred embodiments.

  According to the present invention, it is possible to perform moving image processing adapted to a situation where a special effect cannot be added in real time to a part of a captured moving image.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. The technical scope of the present invention is determined by the claims, and is not limited by the following individual embodiments. In addition, not all combinations of features described in the embodiments are essential to the present invention.

[First Embodiment]
FIG. 1 is an external view of the imaging apparatus 10 according to the first embodiment, and FIG. 2 is a functional block diagram of the imaging apparatus 10. The connector 112 connects the connection cable and the imaging device 10. The recording medium 20 is a randomly accessible recording medium such as a memory card, an optical disk, or a hard disk, and is detachable from the imaging device 10. The recording medium slot 201 is a slot for storing the recording medium 20. The recording medium 20 stored in the recording medium slot 201 can communicate with the imaging device 10. A lid 203 is a lid of the recording medium slot 201.

  A CPU (Central Processing Unit) 11 controls each functional block of the imaging device 10 and a data flow between the functional blocks. The ROM 12 stores a program (firmware) related to the processing procedure of the CPU 11 and various information.

  The display unit 13 is composed of a color liquid crystal display or the like, and is used for displaying an image and displaying a graphical user interface. The display unit 13 also includes a terminal for outputting a video signal to an external display device such as a TV.

  The operation unit 14 includes various buttons such as a release button and a moving image recording start button for receiving an instruction from the user, a cross key, a control wheel, a dial switch, and the like.

  The DRAM 15 is used as a work area of the CPU 11 and has a buffer function for temporarily storing image data, display data, data after image compression, and the like. Normally, data is written to and read from the DRAM 15 via a memory controller, which is not shown here. Although not shown, a DMA controller is provided between each functional block and the DRAM 15 for performing DMA transfer by the CPU 11 without using Read / Write.

  A recording medium interface (I / F) 16 writes and reads image data to and from the recording medium 20 in accordance with instructions from the CPU 11. The CPU 11, the DRAM 15, and the recording medium I / F 16 function as a recording unit that records still images and moving images that are captured images on the recording medium 20.

  The imaging unit 17 includes a lens, a diaphragm, a shutter, and an imaging element such as a CCD sensor or a CMOS sensor.

  The image processing circuit 18 performs processing such as white balance adjustment and pixel interpolation on the image data read from the imaging unit 17 and converts it into YUV data. Further, the image processing circuit 18 resizes the image data to an arbitrary size, and generates display image data to be displayed on the display unit 13 and compression image data to be compressed by the image compression / expansion circuit 19. The image processing circuit 18 adds color / gradation conversion effect, peripheral light amount increase / decrease effect, afterimage effect, and the like to the image data. And special effect processing such as cyclic filter processing.

  The image compression / decompression circuit 19 converts the YUV data into JPEG or H.264 format. H.264 format image data, and JPEG or H.264 format. The compressed image data in the H.264 format is expanded to YUV data.

  The CPU 11, ROM 12, display unit 13, operation unit 14, DRAM 15, recording medium I / F 16, imaging unit 17, image processing circuit 18, and image compression / decompression circuit 19 communicate via an internal bus 30.

  Next, the moving image shooting process of this embodiment will be described. The imaging apparatus 10 can record a moving image with a special image processing effect (special effect) such as a color / gradation conversion effect and a peripheral light amount increase / decrease effect taken. The imaging device 10 determines the special effect to be added to the moving image at the timing when the moving image recording start instruction is given.

  Further, the imaging device 10 shoots a moving image shot during a predetermined time (pre-REC period) immediately before the moving image recording start instruction after the moving image recording start instruction in order to reliably record the moving image at the timing intended by the user. Can be recorded together with video. For this purpose, the imaging device 10 stores moving image compression data before a moving image recording start instruction in a buffer. Then, after the moving image recording is stopped, the imaging device 10 reads the moving image compression data from the buffer and records it with a special effect. In this way, the imaging apparatus 10 can select a special effect appropriate for the subject at the timing of the moving image recording start instruction, and can also record the moving image in the pre-REC period with the special effect.

  With reference to FIG. 3, the outline of the moving image shooting process of the present embodiment will be described. 3A shows a live view display state, FIG. 3B shows a pre-REC data buffer state, FIG. 3C shows a moving image compression state, and FIG. 3D shows a moving image state. The state of the file is shown. In FIG. 3, the hatched frame indicates a frame to which a special effect is added, and the frame without a hatched line indicates a frame to which no special effect is added.

  As shown in FIG. 3A, before the moving image recording start instruction 301 is generated, a moving image 303 shot before the pre-REC period and a moving image 304 (first period) shot during the pre-REC period (first period). No special effects are added to any of the videos. Accordingly, before the moving image recording start instruction 301 is generated, live view display without a special effect is performed. A special effect is added to the moving image 305 (second moving image) shot during the period from the moving image recording start instruction 301 to the moving image recording stop instruction 302 (second period). Accordingly, during the period from the moving image recording start instruction 301 to the moving image recording stop instruction 302, live view display with a special effect is performed.

  As shown in FIG. 3B, the moving image shot during the pre-REC period is stored as pre-REC data 306 in the pre-REC data buffer of the DRAM 15. Before the moving image recording start instruction 301 is generated, the special effect to be added to the moving image is not determined, and the pre-REC data 306 is stored in a state where no special effect is added. That is, in the present embodiment, the moving image that was shot during the pre-REC period and before the special effect is added is held in the volatile recording medium (DRAM 15).

  When the moving image recording start instruction 301 is generated, a special effect to be added to the moving image is determined. Therefore, as shown in FIG. 3C, during the period from the moving image recording start instruction 301 to the moving image recording stop instruction 302, a compressed moving image 307 for recording to which a special effect is added is generated. Further, after the moving image recording stop instruction 302 is generated, a compressed moving image 308 to which a special effect is added is generated from the pre-REC data 306 stored in the pre-REC data buffer.

  As shown in FIG. 3D, a moving image file is generated from the compressed moving image 307 and the compressed moving image 308. In the moving image file, the compressed moving image 308 corresponding to the pre-REC period is combined with the head of the moving image file (before the compressed moving image 307). In the present embodiment, a compressed moving image 307 corresponding to a moving image shot after generation of the moving image recording start instruction 301 is first recorded on the recording medium 20 (nonvolatile recording medium), and then the compressed moving image corresponding to the pre-REC period. 308 is recorded on the recording medium 20.

  As can be understood from FIGS. 3A and 3D, according to the moving image shooting process of the present embodiment, a special effect is added to the moving image shot during the pre-REC period when the live view is displayed. The moving image before being displayed is displayed, and the moving image to which the special effect is added is recorded at the time of recording. In addition, for a moving image shot during a period from the moving image recording start instruction 301 to the moving image recording stop instruction 302, a moving image to which a special effect is added is used for both live view display and recording.

  FIG. 4 is a flowchart of the moving image shooting process performed by the imaging apparatus 10 according to the first embodiment. The processing of each step in this flowchart is realized by the CPU 11 executing a program stored in the ROM 12 unless otherwise specified. When the operation mode of the imaging apparatus 10 is set to the moving image shooting mode by the operation of the operation unit 14, the processing of this flowchart starts.

  In S101, the CPU 11 captures an image captured by the imaging unit 17 as a moving image frame. Then, the CPU 11 uses the image processing circuit 18 to perform processing such as white balance adjustment and pixel interpolation on the captured image data of the moving image frame, converts it into YUV data, and writes it into the DRAM 15.

  In S102, the CPU 11 uses the image processing circuit 18 to resize the display image data size to the YUV data, and generates electronic viewfinder display image data for live view display on the display unit 13. Then, the data is written in the DRAM 15. Here, no special effect is added to the electronic viewfinder display image data.

  In step S <b> 103, the CPU 11 causes the display unit 13 to display electronic viewfinder display image data. Thereby, the live view display image of the display unit 13 is updated. Since special effects are not added to the electronic viewfinder display image data, live view display without special effects is performed here.

  In S104, the CPU 11 uses the image processing circuit 18 to generate moving image compression data (pre-REC data) to be recorded as a moving image in the pre-REC period.

  In S105, the CPU 11 stores the pre-REC data generated in S104 in the pre-REC data buffer of the DRAM 15. At this time, like the electronic viewfinder display image data, no special effect is added to the pre-REC data. The pre-REC data buffer holds at least data corresponding to a moving image of the latest predetermined time (time corresponding to the length of the pre-REC period). Data that is older than the predetermined time may be discarded.

  In S <b> 106, the CPU 11 determines whether or not a moving image recording start instruction has been given by operating the moving image recording button of the operation unit 14. If it is determined that the moving image recording start instruction has not been issued, the CPU 11 returns the process to S101, and performs the same processing for the next captured moving image frame. If it is determined that the moving image recording start instruction has been issued, the CPU 11 advances the process to step S107.

  In step S <b> 107, the CPU 11 determines a special effect pattern to be added to the moving image to be recorded, and stores it in the DRAM 15. Specifically, the CPU 11 determines the presence / absence of the color / gradation conversion effect and the presence / absence of the peripheral light amount increase / decrease effect. The special effect pattern is automatically determined by the CPU 11 based on information such as the movement of the imaging device 10 and the subject, whether the subject is a person, and the brightness and color of the object scene. The CPU 11 stores the determined special effect pattern in the DRAM 15.

  In S108, the CPU 11 captures an image captured by the imaging unit 17 as a moving image frame. Then, the CPU 11 uses the image processing circuit 18 to perform processing such as white balance adjustment and pixel interpolation on the captured image data of the moving image frame, converts it into YUV data, and writes it into the DRAM 15.

  In step S109, the CPU 11 refers to the special effect pattern stored in the DRAM 15 in step S107, and determines whether or not there is a color / gradation conversion effect. If there is no color / gradation conversion effect, the CPU 11 advances the process to step S111. If there is a color / gradation conversion effect, in S110, the CPU 11 performs color / gradation filter processing on the YUV data using the image processing circuit 18 to add the color / gradation conversion effect.

  In S111, the CPU 11 refers to the special effect pattern stored in the DRAM 15 in S107, and determines the presence / absence of the peripheral light amount increase / decrease effect. When there is no effect of increasing / decreasing the peripheral light amount, the CPU 11 advances the process to S113. If there is an effect of increasing / decreasing the peripheral light amount, in S112, the CPU 11 uses the image processing circuit 18 to perform template image composition processing on the YUV data, and adds the effect of increasing / decreasing the peripheral light amount.

  In S113, the CPU 11 uses the image processing circuit 18 to resize the display image data size to the YUV data, and generates electronic viewfinder display image data for live view display on the display unit 13. Then, the data is written in the DRAM 15. Unlike S102, special effects are added to the electronic viewfinder display image data generated here (strictly speaking, it is determined that there is an effect in at least one of S109 and S111).

  In S <b> 114, the CPU 11 causes the display unit 13 to display electronic viewfinder display image data. Thereby, the live view display image of the display unit 13 is updated. Since special effects are added to the electronic viewfinder display image data, live view display with special effects is performed here.

  In step S <b> 115, the CPU 11 uses the image processing circuit 18 to generate moving image compression data to which a special effect corresponding to the special effect pattern stored in the DRAM 15 in step S <b> 107 is added, and writes the data to the DRAM 15.

  In S116, the CPU 11 uses the image compression / decompression circuit 19 to compress the moving image compression data generated in S115 in the MPEG format or the Motion JPEG format.

  In S117, the CPU 11 records the moving image compressed in S116 on the recording medium 20 via the recording medium I / F 16.

  In S <b> 118, the CPU 11 determines whether a moving image recording stop instruction has been issued by operating the moving image recording button of the operation unit 14. If it is determined that the moving image recording stop instruction has not been issued, the CPU 11 returns the process to S108, and performs the same processing for the next captured moving image frame. If it is determined that the moving image recording stop instruction has been issued, the CPU 11 advances the process to step S119.

  In S <b> 119, the CPU 11 reads out one frame of pre-REC data stored in the pre-REC data buffer of the DRAM 15.

  In S120 to S125, the CPU 11 adds a special effect to the frame read in S119 to generate and compress moving image compression data. The processing here is the same as the processing of S109 to S112 and S115 to S116, except that the processing target is a frame of pre-REC data.

  In S <b> 126, the CPU 11 stores the moving image compressed in S <b> 125 in the pre-REC moving image buffer of the DRAM 15.

  In S127, the CPU 11 determines whether or not the processing for all the frames corresponding to the pre-REC period among the pre-REC data stored in the pre-REC data buffer of the DRAM 15 is completed. If there is an unprocessed frame, the CPU 11 returns the process to S119, acquires the next frame from the pre-REC data buffer of the DRAM 15, and performs the same process. If there is no unprocessed frame, the CPU 11 advances the process to S128.

  In S128, the CPU 11 records the moving image stored in the pre-REC moving image buffer of the DRAM 15 in S126 on the recording medium 20 via the recording medium I / F 16. At that time, the CPU 11 combines the moving image stored in the pre-REC moving image buffer with the head of the moving image recorded in the recording medium 20 in S117.

  As described above, according to the first embodiment, the imaging device 10 determines a special effect when a moving image recording start instruction is given, and the moving image shot in the pre-REC period before the moving image recording start instruction Then, the moving image shot after the moving image recording start instruction is recorded. Therefore, the imaging device 10 cannot add a special effect in real time to a moving image shot during the pre-REC period. Therefore, the imaging device 10 displays a video before the special effect is added during live view display and a video with the special effect added during recording for the video shot during the pre-REC period. Record. As described above, according to the present embodiment, the imaging device 10 performs moving image processing adapted to a situation in which a special effect cannot be added in real time to a part of the captured moving image.

  In the above description, the imaging apparatus 10 determines the special effect when the moving image recording start instruction is given, but the timing for determining the special effect is not limited to this. At any decision timing, the imaging device 10 displays a movie before the special effect is added at the time of live view display, and a special effect is recorded at the time of recording. What is necessary is just to record the added moving image.

  In the above description, the timing for determining the special effect matches the timing for starting the live view display with the special effect added. That is, the end of the period during which the live view display with no special effect is performed is the special effect determination timing. However, both timings do not need to match. For example, the imaging device 10 performs live view display for a video shot before a predetermined time after the determination timing, using a video before the special effect is added, and for a video shot after that, the special effect is displayed. Live view display may be performed by a moving image to which is added.

[Second Embodiment]
In the first embodiment, a configuration has been described in which a special effect is added to a moving image shot during the pre-REC period after an instruction to stop moving image recording. In other words, in the first embodiment, a moving image that has been shot after the moving image recording start instruction is added and a special effect is added is first recorded on the recording medium 20, and then a special effect is applied to the moving image that is shot in the pre-REC period. Added and recorded on the recording medium 20. On the other hand, in the second embodiment, a special effect is added to the moving image shot during the pre-REC period before the moving image shot after the instruction to start moving image recording and added with the special effect is recorded on the recording medium 20. A configuration for recording on the recording medium 20 will be described. In the second embodiment, the basic configuration of the imaging apparatus 10 is the same as that of the first embodiment (see FIGS. 1 and 2). Hereinafter, differences from the first embodiment will be mainly described.

  With reference to FIG. 5, the outline of the moving image shooting process of the present embodiment will be described. 5A shows a live view display state, FIG. 5B shows a pre-REC data buffer and a moving image compression data buffer, and FIG. 5C shows a moving image compression state. 5 (d) shows the state of the moving image file. In FIG. 5, a hatched frame indicates a frame to which a special effect is added, and a frame without a hatched line indicates a frame to which no special effect is added.

  As shown in FIG. 5A, before the moving image recording start instruction 501 occurs, a moving image 503 shot before the pre-REC period and a moving image 504 (first period) shot during the pre-REC period (first period). No special effects are added to any of the videos. Therefore, before the moving image recording start instruction 501 is generated, live view display without a special effect is performed. A special effect is added to the moving image 505 (second moving image) shot during the period from the moving image recording start instruction 501 to the moving image recording stop instruction 502 (second period). Accordingly, during the period from the moving image recording start instruction 501 to the moving image recording stop instruction 502, live view display with a special effect is performed.

  As shown in FIG. 5B, the moving image shot during the pre-REC period is stored as pre-REC data 506 in the pre-REC data buffer of the DRAM 15. Before the moving image recording start instruction 501 is generated, the special effect to be added to the moving image is not determined, and the pre-REC data 506 is stored in a state where the special effect is not added. In addition, a moving image shot during a period from the moving image recording start instruction 501 to the moving image recording stop instruction 502 is stored as moving image compression data 507 in a moving image compression data buffer of the DRAM 15 with a special effect added. . That is, in the present embodiment, a moving image shot during the pre-REC period and before the special effect is added, and a moving image shot after the moving image recording start instruction 501 is generated and added with the special effect are recorded in a volatile manner. It is held in a medium (DRAM 15).

  When the moving image recording start instruction 501 is generated, a special effect to be added to the moving image is determined. As shown in FIGS. 5C and 5D, in this embodiment, after the moving image recording start instruction 501 is generated, a special effect is added to the pre-REC data 506, and a compressed moving image 508 is generated. , Recorded as a video file. Thereafter, a compressed moving image 509 is generated from the moving image compression data 507 and recorded as a moving image file. That is, the process of generating and recording the compressed moving image 509 from the moving image compression data 507 is executed with a delay corresponding to the length of the pre-REC period.

  FIG. 6 is a flowchart of the moving image shooting process performed by the imaging apparatus 10 according to the second embodiment. In FIG. 6, steps in which the same or similar processing as in FIG. 4 is performed are denoted by the same reference numerals. The processing of each step in this flowchart is realized by the CPU 11 executing a program stored in the ROM 12 unless otherwise specified. When the operation mode of the imaging apparatus 10 is set to the moving image shooting mode by the operation of the operation unit 14, the processing of this flowchart starts.

  In S215, the CPU 11 uses the image processing circuit 18 to generate moving image compression data to which a special effect corresponding to the special effect pattern stored in the DRAM 15 in S107 is added.

  In S216, the CPU 11 stores the moving image compression data to which the special effect generated in S215 is added in the moving image compression data buffer of the DRAM 15.

  In S217, the CPU 11 determines whether or not the processing for all the frames corresponding to the pre-REC period among the pre-REC data stored in the pre-REC data buffer of the DRAM 15 is completed. If there is an unprocessed frame, the CPU 11 advances the process to step S119. In this case, in S119 to S124, as in the first embodiment, addition of special effects, generation of moving image compression data, and the like are performed for one frame in the pre-REC period. If there is no unprocessed frame, the CPU 11 advances the process to step S224.

  In S224, the CPU 11 determines whether or not the processing has been completed for all frames of the moving image compression data stored in the moving image compression data buffer of the DRAM 15 in S216. If there is no unprocessed frame, the CPU 11 ends the process of this flowchart. Until it is determined in S228 that will be described later that a moving image recording stop instruction has been issued, a new frame is repeatedly stored in S216, and therefore there is always an unprocessed frame. When there is an unprocessed frame, the CPU 11 advances the process to S225.

  In S225, the CPU 11 reads out one frame of moving image compression data stored in the moving image compression data buffer of the DRAM 15.

  In S226 following S124 or S225, the CPU 11 uses the image compression / decompression circuit 19 to compress the moving image compression data generated in S124 or the moving image compression data read out in S225 in the MPEG format or the Motion JPEG format.

  In S227, the CPU 11 records the moving image compressed in S226 on the recording medium 20 via the recording medium I / F 16.

  In S <b> 228, the CPU 11 determines whether a moving image recording stop instruction has been issued by operating the moving image recording button of the operation unit 14. If it is determined that the moving image recording stop instruction has not been issued, the CPU 11 returns the processing to S208, performs the same processing for the next captured moving image frame in S208 to S216, and then performs the processing after S217. . When it is determined that the moving image recording stop instruction has been issued, the CPU 11 returns the process to S217. In this case, when the processing for all the frames corresponding to the pre-REC period is completed and the processing for all the frames taken after the moving image recording start instruction is completed, the determinations in S217 and S224 are both “YES”, and this flowchart This process ends.

  As described above, according to the second embodiment, the imaging device 10 is photographed during the pre-REC period before the moving image with special effects added and recorded after the moving image recording start instruction is recorded on the recording medium 20. A special effect is added to the recorded moving image and recorded on the recording medium 20. As described above, according to the present embodiment, the imaging device 10 performs moving image processing adapted to a situation in which a special effect cannot be added in real time to a part of the captured moving image.

  As in the first embodiment, the timing for determining the special effect is not limited to the timing for instructing to start moving image recording. The timing for determining the special effect and the timing for starting the live view display with the special effect added may not coincide with each other.
