In detail, the user interface 120 may display an image captured by a user's imaging command, or may display an image corrected by the image processor 150 to be described later. In addition, the user interface 120 may display the captured video.

In addition, the user interface 120 may display a live-view image. In detail, the user interface 120 may display a live-view image captured by the imager 140, which will be described later, based on a live-view display command of the user. In this case, the live-view is a function of displaying an image captured by the imaging unit 140 in a user interface window instead of the viewfinder.

 The storage unit 130 stores the photographed image. In detail, the storage 130 may temporarily store images captured by the imaging unit 140 to be described later, frame by frame. The storage unit 130 may store an image processed by the image processor 150 to be described later, and the storage unit 130 may store a video generated by the encoding unit 160 to be described later. In addition, the storage 130 may store an image generated in response to the dual capture command.

The storage unit 130 may be a storage medium and an external storage medium in the photographing apparatus 100, for example, a removable disk including a USB memory, a flash memory, a storage medium connected to the photographing apparatus, a web server through a network. ) May be implemented.

The imaging unit 140 picks up an image. In this case, the imaging unit 140 may photograph a plurality of images continuously. Specifically, the imaging unit 140 collects the light of the subject to form an optical image in the imaging area, an imaging device for photoelectric conversion of light incident through the lens into an electrical signal, and an analog signal of the imaging device as a digital signal. It can be configured as an AD converter that converts and outputs. In this case, the imaging device may be a charge coupled device (CCD) imaging device and a complementary metal oxide semiconductor (CMOS) imaging device.

The image processor 150 may perform a correction operation on the image generated by the imaging unit 140. In detail, the image processor 150 performs signal processing such as digital zoom, AWB (Auto White Balance), AF (Auto Focus), AE (Auto Exposure), etc., on the generated image to adjust format conversion and image scale. can do.

The encoder 160 generates a video by compressing the plurality of photographed images. In detail, the encoder 160 encodes an image of a predetermined viewpoint among the plurality of images photographed by the imaging unit 140 into an intra frame, and encodes an image other than the predetermined viewpoint into an inter frame. can do. In this case, the encoder 160 may receive a plurality of images directly from the image capturer 140, and may receive a plurality of images processed by the image processor 150. A detailed operation of the encoder 160 will be described later with reference to FIGS. 2 to 4.

Meanwhile, in the present embodiment, the contents of receiving a voice signal have not been described. However, the encoder 160 may generate a video file combining a plurality of images captured by a voice signal received through a separate internal microphone or an external microphone. Can be generated.

The meta information inserting unit 170 adds the video frame information corresponding to the time point at which the dual capture command is received to the meta information of the video. The detailed operation of the meta information insertion unit 170 will be described later with reference to FIGS. 2 to 4.

The controller 180 controls each component in the photographing apparatus 100. In detail, when a photographing command is input, the controller 180 controls the imaging unit 140 to photograph a plurality of images continuously. If the dual capture command is input through the user interface unit 120 during shooting, the controller 180 may control the image processor 150 to store the captured image as a separate image file when the dual capture command is input. Can be. The controller 180 may control the meta information insertion unit 170 to add video frame information corresponding to the time when the dual capture command is input to the meta information of the video.

As described above, the photographing apparatus 100 according to the present exemplary embodiment may generate a video including the information of the frame at the time when the dual capture command is input. Accordingly, the apparatus for reproducing the moving image can easily display the thumbnail image of the time of dual capture by using the information of the frame included in the moving image.

Meanwhile, in the description of FIG. 1, the meta information insertion unit 170 adds only frame information to the video meta information. However, in the implementation, the information of the still image generated by the image processing unit 150 is also included in the video meta. It can also be implemented in the form of adding to information.

2 is a view for explaining an operation of the photographing apparatus according to the first embodiment.

Specifically, in the operation of the photographing apparatus according to the first embodiment, when a dual capture command is input during video recording, the image at the time of receiving the dual capture command is stored as a separate still image and the time of receiving the dual capture command This operation adds frame information as meta information of a video.

Referring to FIG. 2, when receiving a video capturing command from the user, the controller 180 controls the capturing unit 140 to continuously photograph an image. When storing a plurality of images continuously photographed as they are, since the capacity of the resultant is too large, most photographing apparatuses compress and store a plurality of images continuously photographed by using an image codec in real time.

Accordingly, the encoder 160 encodes an image of a predetermined viewpoint among the plurality of photographed images into an intra frame. Herein, an intra frame (or I frame) is a frame that can be independently decoded without referring to a previous frame or a later frame. In the figure the intra frame is indicated by I. The predetermined time point may have a predetermined period. For example, the example of FIG. 2 has a period of 5 frames, but may be implemented in various frame periods other than the implementation.

The encoder 160 encodes an image other than a predetermined viewpoint into an inter frame. Here, the inter frame is a frame that must refer to a previous frame and / or a later frame but can be decoded. In the figure, the inter frame is denoted by P. In the illustrated example, only the P frame that can be decoded with reference to the previous frame is illustrated. However, the implementation may be performed using a B frame or a codec that uses a mixture of 'P frame and B frame'.

When a dual capture command is input during the encoding process, the controller 180 may control the image processor 150 to store an image captured by the imaging unit 140 as a still image at the time when the dual capture command is input. In this case, the meta information inserting unit 170 generates information of the frame (specifically, information of the third I frame and the number of the first P frame after the third I frame) at the time when the dual capture command is input as meta information. Can be inserted into the video. In this case, the information of the I frame may be stored as stream file size information of the meta information.

3 is a view for explaining the operation of the photographing apparatus according to the second embodiment.

Specifically, in operation of the photographing apparatus according to the second embodiment, if a dual capture command is input during video recording, the image at the time of receiving the dual capture command is stored as a separate still image, and the intra frame of the encoding unit 160 is operated. According to an embodiment of the present invention, the time point for encoding the video data is changed.

Referring to FIG. 3, upon receiving a video capturing command from the user, the controller 180 controls the capturing unit 140 to continuously photograph an image.

Accordingly, the encoder 160 encodes an image of a predetermined viewpoint among the plurality of photographed images into an intra frame. The encoder 160 encodes an image other than a predetermined viewpoint into an inter frame.

When a dual capture command is input during the encoding process, the controller 180 may control the image processor 150 to store an image captured by the imaging unit 140 as a still image at the time when the dual capture command is input. The controller 180 may control the encoder 160 to encode the image at the time when the dual capture command is input into the intra frame.

In this case, the meta information inserting unit 170 may insert information of the frame (specifically, information of the fourth I frame) at the time when the dual capture command is input into the video generated as meta information.

When a video is generated by this process, the video frame at the time of dual capture is always an intra frame, and the device displaying the thumbnail does not need to decode the previous frame or the subsequent frame to use the corresponding intra frame. You can easily create thumbnail images.

In FIG. 3, the preset time point for encoding the intra frame is reset and described as the time when the dual capture command is input. However, the preset time point is not reset, and the intra frame is formed only when the dual capture command is input. It can also be implemented in the form. For example, it may be implemented in the form of “… II (dual capture time point) PPIPPP…”.

4 is a diagram for describing an operation of a photographing apparatus according to a third embodiment.

Specifically, in the operation of the photographing apparatus according to the third embodiment, the latest photographing apparatus is capable of high-speed photographing at 60 frames per second, and does not use the exact point of time when the dual capture is input. The operation of storing an image corresponding to an adjacent intra frame as a separate still image and adding frame information corresponding to the intra frame as meta information of the video.

Referring to FIG. 4, when receiving a video capturing command from the user, the controller 180 controls the capturing unit 140 to continuously photograph an image.

Accordingly, the encoder 160 encodes an image of a predetermined viewpoint among the plurality of photographed images into an intra frame. In addition, the encoder 160 encodes an image other than a predetermined viewpoint into an inter frame.

When the dual capture command is input during the encoding process, the controller 180 may control the image processor 150 to store an image corresponding to the intra frame closest to the time when the dual capture command is input as a still image. In this case, the meta information inserting unit 170 may insert information of the intra frame closest to the time when the dual capture command is input (specifically, information of the third I frame) into the video generated as meta information.

When the video is generated by the above process, the video frame corresponding to the meta information is always an intra frame, and the device displaying the thumbnail does not need to decode the previous frame or the subsequent frame and decodes only the corresponding intra frame. You can easily create thumbnail images.

In FIG. 4, only an example of using an intra frame before a time point at which the dual capture command is input is illustrated and described, but may be implemented in a form using an intra frame after the time point at which the dual capture command is input.

Meanwhile, in FIGS. 2 to 4, only a single dual capture command is input during video recording to generate one still image corresponding thereto, but a plurality of dual capture commands may be input during video recording. In addition, the operation as described above may be repeatedly performed for each dual capture command.
