Description

  The present invention relates to an imaging apparatus, an imaging method, and a program. In particular, the present invention relates to an imaging apparatus and imaging method for imaging a moving image and a still image, and a program for the imaging apparatus.

2. Description of the Related Art Conventionally, there is a movie still camera that can obtain a moving image without dropping frames even if a still image is shot during recording of the moving image (see, for example, Patent Document 1). In this movie still camera, moving image data having one frame of 640 pixels in the horizontal direction and 480 pixels in the vertical direction is obtained at a constant cycle during recording of the moving image. When the release button is pressed during recording of moving image data, still image data of 1280 pixels in the horizontal direction and 960 pixels in the vertical direction is acquired and recorded on the memory card. At this time, a reduced image having the same size as the single frame image for moving images is generated from the still image data, and is inserted at the position where the still image data is obtained.

  Note that the above summary of the invention does not enumerate all the necessary features of the present invention, and sub-combinations of these feature groups can also be the invention.

  According to the present invention, it is possible to provide an imaging apparatus capable of obtaining a moving image in which the motion of a subject does not become discontinuous during moving image reproduction even when a still image is captured during moving image capturing.

  Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the claimed invention, and all combinations of features described in the embodiments are inventions. It is not always essential to the solution.

  FIG. 1 shows an example of a usage environment of an imaging system 100 according to an embodiment of the present invention. If the release button for capturing a still image is pressed by the imager 190 while capturing a frame image for a moving image at a fixed period, the image capturing apparatus 110 instead of capturing a moving image frame image A still image is captured with an exposure time shorter than the exposure time for capturing an image. At this time, the imaging device 110 captures an image with an earlier exposure start time for capturing a frame image to be captured next to the captured still image. The imaging device 110 records a frame image captured at an earlier exposure start time as a frame image at the timing at which the frame image was originally captured, and also as a frame image captured at the timing at which a still image was captured. Record. The display device 120 receives the frame image and the still image captured by the imaging device 110 via a communication line such as the Internet and a recording medium such as a semiconductor memory. And the display apparatus 120 reproduces | regenerates as a moving image by reproducing | regenerating a frame image continuously.

  Note that the imaging apparatus 110 may record a frame image captured with an earlier exposure start time, with the fact that the image was captured with an earlier exposure start time. Then, when the display device 120 continuously displays the frame images received from the imaging device 110, if the displayed frame image is attached to the effect that the exposure was started earlier, The frame image may be displayed again.

  The imaging device 110 may be an imaging device such as a digital still camera or a digital video camera, or may be a mobile information terminal having an imaging function, such as a mobile phone with a camera or a PDA. The display device 120 may be a device that displays moving images, such as a personal computer, an electronic album, an electronic photo stand, and an HDTV.

  According to the imaging system 100 described above, the imaging device 110 can prevent the movement of the subject from becoming discontinuous before and after the timing at which a still image is captured during moving image reproduction. For this reason, the imager 190 can capture a still image at any timing without missing a photo opportunity during moving image capturing.

  FIG. 2 shows an example of a block configuration of the imaging apparatus 110. The imaging apparatus 110 includes a moving image capturing control unit 200, a still image capturing instruction receiving unit 201, a still image capturing control unit 202, an exposure time control unit 204, an exposure control unit 206, an imaging unit 210, a still image capturing timing recording unit 208, a moving image A storage unit 212, an image storage control unit 214, a display control unit 216, a display unit 218, and a moving image output unit 219 are provided.

  The imaging unit 210 captures a frame image and a still image. Specifically, the imaging unit 210 images the subject by exposing light from the subject to an imaging element such as a CCD. The moving image capturing control unit 200 causes the imaging unit 210 to capture a moving image including a plurality of frame images at a predetermined frame period. The moving image capturing control unit 200 causes the imaging unit 210 to capture a moving image including a plurality of frame images at a predetermined frame period.

  The still image capturing instruction receiving unit 201 receives a still image capturing instruction when the image capturing unit 210 is capturing a first frame image. Specifically, the still image capturing instruction accepting unit 201 accepts, as a still image capturing instruction, the photographer 190 pressing the release button for capturing a still image. The still image capturing control unit 202 captures a still image instead of the first frame image captured by the image capturing unit 210 when the still image capturing instruction receiving unit 201 receives a still image capturing instruction. The image is taken by the unit 210.

  At this time, the exposure time control unit 204 is configured such that when the still image capturing control unit 202 causes the image capturing unit 210 to capture a still image instead of the first frame image, the image capturing unit 210 captures the next image after the still image. In the exposure operation for acquiring the second frame image, when the still image capturing control unit 202 does not cause the image capturing unit 210 to capture a still image, the image capturing unit 210 captures the second frame image after the first frame image. This is started at an earlier timing than the exposure operation for acquiring the frame image. For this reason, the trajectory of the movement of the subject in the vicinity of the timing when the imaging device 110 captures a still image can be stored in the frame image.

  Note that the exposure time control unit 204 is a second unit that the imaging unit 210 captures after the still image when the still image capturing control unit 202 causes the imaging unit 210 to capture a still image instead of the first frame image. When the still image capturing control unit 202 does not cause the image capturing unit 210 to capture a still image, the image capturing unit 210 captures a second image captured after the first frame image. The process is terminated at substantially the same timing as the exposure operation for acquiring the frame image. Thereby, the miracle of the movement of the subject to be imaged when the image is captured at a predetermined frame period when the still image is not captured can be included in the frame image captured after the still image.

  The moving image storage unit 212 stores a plurality of frame images captured by the imaging unit 210. Then, the image storage control unit 214, when the still image capturing control unit 202 does not cause the image capturing unit 210 to capture a still image, the first frame image and the second frame that the image capturing unit 210 should have captured. As the image, the second frame image picked up by the exposure time control unit 204 being controlled at an early timing for starting the exposure operation is stored in the moving image storage unit 212. As a result, an image including a locus of movement of the subject at a time closer to the timing at which the still image is captured can be recorded as a frame image that could not be acquired by capturing the still image.

  The display unit 218 displays a moving image. Specifically, the display unit 218 displays a moving image by continuously displaying frame images captured by the moving image storage unit 212. Since the frame image picked up by the moving image pickup control unit 200 with the start of the exposure operation accelerated contains the locus of movement of the subject at a timing closer to the timing at which the still image was picked up, It is possible to prevent the movement of the subject from appearing discontinuously before and after the timing when the image is captured.

  The exposure control unit 206 is used when the image capturing unit 210 captures the second frame image when the still image capturing control unit 202 causes the image capturing unit 210 to capture a still image instead of the first frame image. When the still image capturing control unit 202 does not cause the image capturing unit 210 to capture a still image, the exposure value is controlled to be smaller than the exposure value when the image capturing unit 210 captures the second frame image. Specifically, the exposure control unit 206 controls the exposure amount per time for the image sensor of the image capturing unit 210 by controlling the aperture value. More specifically, the exposure control unit 206 exposes the exposure amount during the exposure period when capturing a frame image before capturing a still image and the exposure during the exposure period when capturing a frame image captured after the still image. The aperture value is set based on the exposure time set by the exposure time control unit 204 so that the amount is substantially the same. As a result, the imaging unit 210 can align the brightness of the frame image captured by accelerating the exposure operation and the brightness of the frame image captured at a predetermined frame period.

  Note that the moving image storage unit 212 may store a frame image captured by controlling the timing at which the exposure operation is started early as either the first frame image or the second frame image. The display control unit 216 is configured to display a first frame image to be displayed on the display unit 218 when the still image capturing control unit 202 does not cause the imaging unit 210 to capture a still image. The second frame image captured by the imaging unit 210 may be displayed on the display unit 218 in both the second display period in which the display unit 218 displays the second frame image captured by the imaging unit 210.

  Specifically, the still image capturing timing recording unit 208 captures the first frame image when the still image capturing control unit 202 causes the image capturing unit 210 to capture a still image instead of the first frame image. The moving image storage unit 212 records still image recording information indicating that the unit 210 is the same as the second frame image captured next to the still image. The still image recording information may be, for example, tag information attached to the second frame image indicating that the second frame image should be displayed continuously. In addition, tag information or the like attached to the frame image F1 may indicate that the image content is the same as that of the second frame image. The display control unit 216 causes the display unit 218 to display the second frame image during the first display period and the second display period when the still image recording information is recorded in the moving image storage unit 212. . For this reason, the imaging device 110 only needs to add supplementary information when continuously displaying the same frame image, and does not record the same frame image in the first frame image and the second frame image. I'll do it.

  As described above, according to the imaging apparatus 110 in the present embodiment, after capturing a still image, the subject movement near the timing of capturing the still image is performed by capturing the frame image with the exposure time advanced. Can be stored in a frame image. For this reason, even when a still image is captured during moving image capturing, it is possible to easily generate moving image data in which the motion of the subject does not appear discontinuous during moving image reproduction.

  Note that the moving image output unit 219 provides the display device 120 with a plurality of frame images stored in the moving image storage unit 212. The display device 120 may have a function of displaying a moving image, similar to the display control unit 216 and the display unit 218.

  FIG. 3 is a diagram illustrating an example of a moving image and still image imaging process by the imaging device 110. In the example of this figure, the moving image imaging control unit 200 exposes the imaging element of the imaging unit 210 for an exposure time Lm with an aperture value α from an exposure start time t301a, t302a, t303a,. At this time, when there is an instruction to capture a still image while the exposure period (t302a to t302a + Lm) from the exposure start time t302a ends, the still image capturing control unit 202 is shorter than the exposure time Lm of the frame image. In the exposure time Ls, the image sensor of the imaging unit 210 is exposed to capture a still image. At this time, when the exposure has already started from the exposure start time t302a of the frame image, the still image capturing control unit exposes the exposure element of the imaging unit 210 until the exposure start time t302b of the still image. The accumulated charge is discharged once.

  The exposure time control unit 204 sets the exposure start time for capturing the frame image F2 to a time t303a ′ before the exposure start time t303a for starting the exposure operation when the still image S is not captured. The exposure end time is set to the exposure end time t303a + Lm of the frame image to be captured next to the still image. At this time, the exposure control unit 206 calculates the exposure time Lm ′ (= t303a + Lm−t303a ′) set by the exposure time control unit 204, and uses the exposure time Lm as an aperture value when capturing the frame image F2. A value obtained by multiplying the aperture value α for exposure by the exposure time Lm ′ / Lm is set. Thereby, the brightness of the frame images before and after capturing a still image can be made uniform.

  Through the imaging operation described above, the imaging apparatus 110 acquires and records the frame image F0, the still image S, and the frame image F2 captured after the still image S, which are captured before the still image S. Then, the image storage control unit 214 stores the frame image F2 in the moving image storage unit 212 as a frame image to be captured by exposing it from the exposure start time t303a, and by capturing it from the exposure start time t302a. Also, the frame image F2 is stored in the moving image storage unit 212 as the frame image F1 to be processed. For this reason, the imaging device 110 can record the frame image F1 including the locus of the subject before the time t303a. For this reason, even if the display unit 218 continuously reproduces the frame images F0, F1, and F2, the movement of the subject does not appear discontinuous.

  FIG. 4 is a diagram illustrating an example of a processing flow for displaying a frame image as a moving image. In the example of this figure, when the frame image F1 cannot be captured by capturing the still image S, the still image capturing timing recording unit 208 records the continuous display flag in the tag information of the frame image F2. An example of the operation flow is shown. The display control unit 216 causes the display unit 218 to display the frame image stored in the moving image storage unit 212 for a display period corresponding to the frame period (S402). Then, the display control unit 216 determines whether or not the continuous display flag is recorded in the frame image displayed in S402 (S404).

  In S404, if the continuous display flag is recorded in the frame image displayed in S402, the display control unit 216 displays the frame image displayed on the display unit 218 in S402 as a display period corresponding to the frame period. It is displayed again (S406). Then, the display control unit 216 determines whether or not the last frame image to be displayed has been displayed (S408). When the last frame image to be displayed is displayed in S408, the display control unit 216 ends the process. In S408, when the last frame image to be displayed is not displayed, the display control unit 216 shifts the process to S402 to display the next frame image. In S404, when the continuous display flag is not recorded in the frame image displayed in S402, the display control unit 216 shifts the process to S408.

  By the reproduction operation by the display control unit 216 described above, it is not necessary to record the frame image F2 picked up earlier in the exposure operation as the frame image F1.

  As described above, according to the imaging apparatus 110 of the present embodiment, even when a still image is captured instead of a frame image during moving image capturing, it is possible to generate moving image data that appropriately reflects the motion of the subject. . Further, the imaging apparatus 110 can generate moving image data that does not make the viewer feel unnatural without performing complicated processing such as image recognition and processing that requires time.

  FIG. 5 shows an example of a hardware configuration of a computer 1500 related to the imaging apparatus 110.

A moving image capturing control unit that causes the image capturing unit to capture a moving image including a plurality of frame images at a predetermined frame period;
A still image capturing instruction receiving unit that receives a still image capturing instruction when the image capturing unit captures the first frame image;
When the still image capturing instruction accepting unit accepts a still image capturing instruction, the still image capturing control unit causes the image capturing unit to capture a still image instead of the first frame image captured by the image capturing unit. ,
When the still image capturing control unit causes the image capturing unit to capture a still image instead of the first frame image, exposure for acquiring a second frame image captured next to the still image by the image capturing unit When the still image capturing control unit does not cause the image capturing unit to capture a still image, an exposure operation for the image capturing unit to acquire a second frame image captured after the first frame image A program that functions as an exposure time control unit that starts at an earlier timing.
