1 is a block diagram briefly illustrating the configuration of an electronic device 100, in accordance with one embodiment of the present invention. 1, the electronic device 100 includes an image obtaining unit 110, a determining unit 120, a dividing unit 130, a packaging unit 140, an encoding unit 150, and a storage unit 160. [ . In this case, the electronic device 100 may be an image pickup device such as a camera. However, the present invention is not limited to a mobile phone, a tablet PC, a camcorder, a notebook PC, a PDA, a PDP, And the like.

The image obtaining unit 110 is a component for obtaining an image frame. The image obtaining unit 110 may include a photographing unit (not shown). That is, the image acquisition unit 110 may acquire an image frame by taking an image through a photographing unit (not shown). In particular, the photographing unit (not shown) can acquire a plurality of image frames using the continuous photographing mode. At this time, the plurality of image frames may be images related to each other.

The photographing unit (not shown) can receive the image of the subject by converting the optical signal input through the lens into an electrical signal through the image sensor. At this time, the object refers to all the objects including the main subject and background in the generated captured image. The technical features of the photographing unit (not shown) are well known in the art, and a detailed description thereof will be omitted.

The image acquisition unit 110 acquires an image frame through an image pickup unit (not shown), and the image acquisition unit 110 receives and acquires an image frame from an external device connected by wire or wireless The image frame can be obtained by various methods.

The determination unit 120 is a component for determining the number of image frames included in one compressed file and the number of divided images for an image frame.

One compressed file contains a predetermined number of image frames. For example, in the case of compressing an I-frame, a P-frame, and a B-frame in order to increase compression efficiency, compressing "I-frame, P-frame, P- The number of image frames included in the file is three.

The number of divisions for an image frame means the number of divisions of each image frame by the same size. That is, the resolution of the storable image is preset in the electronic device 100. Accordingly, when the resolution of the image obtained through the image acquisition unit 110 is larger than the resolution of the image that can be stored, the acquired image frame should be divided according to the resolution of the storable image. Therefore, the number of divisions for an image frame means the number of image frames divided by the same size in order to store the image at a constant resolution.

Meanwhile, the dividing unit 130 is a component for dividing each of a plurality of image frames into regions having the same size according to the determined number of divisions when a plurality of image frames are acquired through the image obtaining unit 110. [

That is, when it is decided to divide each image frame into four regions through the decision unit 120, the dividing unit 130 can divide each of the plurality of image frames into four regions having the same size.

Also, the partitioning unit 130 may padding the additional area for each of the plurality of image frames, and may divide the padded image frame into areas of the same size.

That is, the partitioning unit 130 may divide the image frame into the image resolution that can be stored through the storage unit 160, according to the hardware characteristics of the electronic device 100.

Accordingly, when the resolution of the image frame is not an integral multiple of the resolution of the image that can be stored through the storage unit 160, the partitioning unit 130 divides the resolution of the image frame, which can be stored through the storage unit 160, Lt; RTI ID = 0.0 > a < / RTI >

Meanwhile, the packaging unit 140 is a component for packaging a plurality of image frames. Specifically, the packaging unit 140 packages a plurality of image frames according to the number of image frames included in one compression file determined through the determination unit 120. [

When a plurality of image frame regions are divided through the division unit 130, the packaging unit 140 packages a plurality of image frames for each divided region. For example, when each image frame is divided into two areas of a left-frame and a right-frame, and the number of image frames included in one compressed file is 3, The left frame of the third frame may be packaged as one, and the right frame of the first frame to the third frame may be packaged as one.

Meanwhile, the encoding unit 150 is a component for compressing the packaged image frame. In particular, the encoding unit 150 may encode the packaged image frame in a moving image format such as MPEG. That is, the encoding unit 150 may encode the packaged image frame into a moving image format having a predetermined resolution. For example, when the electronic device 100 stores an image frame in a standard definition (SD) resolution, the encoding unit 150 may encode and store the image frame at a resolution of 720 x 480.

In addition, the encoding unit 150 may encode a plurality of thumbnail images corresponding to a plurality of image frames in a packaged image frame.

The storage unit 160 is a component for storing a compressed image frame. The storage unit 160 may store various types of images encoded in a still image format such as JPEG or a moving image format such as MPEG.

Meanwhile, the electronic device 100 may further include a header information generating unit (not shown). That is, the header information generating unit (not shown) may generate header information to be packaged and compressed with a plurality of image frames.

The header information may include information regarding the number of acquired image frames, the number of image frames included in one compressed file, and the number of divided images for an image frame. In addition, the header information may include information on the horizontal length and the vertical length of the divided image frame. A detailed description of the header information will be given later.

Meanwhile, the electronic device 100 may include a decoding unit (not shown) and a user input unit (not shown).

The decoding unit (not shown) is a component for decoding the compressed and stored image frame. The encoding unit 150 and the decoding unit (not shown) of the electronic device 100 may be an MPEG encoder and an MPEG decoder for storing image frames in a moving image format. In addition, both the MPEG encoder and the MPEG decoder circuit may be circuits conforming to the H.264 standard. In order to simplify the explanation, the circuit configuration of the MPEG decoder will be described as an example. The MPEG decoder includes an entropy decoding unit for receiving an NAL (Network Abstraction Layer), which is a compressed bit stream, to perform entropy decoding, A de-quantization unit for de-quantizing the data output from the reordering unit, and an inverse-discrete cosine transform unit for performing inverse-discrete cosine transform on the de-quantized data, an intra / inter-data prediction unit for performing and compensating intra-picture prediction or inter-picture prediction, an inverse discrete cousing transform (IDCT) And may include an in-loop deblocking filter.

On the other hand, when a user command for displaying an image frame is inputted through a user input unit (not shown), a decoding unit (not shown) analyzes the header information included in the compressed file and decodes the compressed file according to the analysis result . Also, when the image frame is divided and encoded, a decoding unit (not shown) may merge the divided regions into one image.

With the above-described electronic device, the user can use the method of dividing or padding and dividing the image frame, without separately including the encoding unit for encoding the image frame according to the plurality of resolutions, Encoded and stored.

Hereinafter, a method of dividing and storing an image frame will be described in detail with reference to FIG. 2 to FIG.

2 is a diagram illustrating a method of encoding an image by the encoding unit 150 and padding an additional region in the acquired image according to the resolution and dividing the additional region.

For example, if the resolution of the acquired image 210 of FIG. 2 is 2592 x 1944 and the resolution of the storable image of the electronic device 100 is 3840 x 2160, which is UHD (ultra high density) resolution, then the electronic device 100 The additional area 220 may be padded for each of a plurality of image frames without dividing the image frame so that the resolution of the image frame is 3840 x 2160 and stored. That is, in the above-mentioned example, the tiling step of FIG. 2 will be unnecessary.

On the other hand, when the resolution of the acquired image 210 of FIG. 2 is 2592 x 1944 and the resolution of the storable image of the electronic device 100 is 1920 x 1080, which is the resolution of Full HD, a tiling step for dividing the image frame is required Do.

More specifically, since the resolution of the storable image of the electronic device 100 is 1920 x 1080, which is the resolution of full HD, if the acquired image 210 is simply divided into quadrants, the resolution of each divided image frame becomes 1296 x 972, It is not suitable for the hardware characteristics of the apparatus 100.

Thus, the electronic device 100 paddes the additional area for each of the plurality of image frames before dividing the image. That is, the electronic device 100 can padd the additional area for each of the plurality of image frames so as to have a resolution of a multiple of 1920 x 1080, which is the resolution of the storable image.

Specifically, in order to be a size that can include the acquired image 210 having a resolution of 2592 x 1944, the electronic device 100 can acquire the acquired image 210 so as to have a resolution twice as high as the resolution of the recordable image 1920 x 1080, The additional area 220 may be padded.

Thus, the electronic device 100 can padding the additional area 220 in the acquisition area 210 so that the resolution of the entire frame is 3840 x 2160.

The electronic device 100 divides the image frame into which the additional area 220 is padded into four equal sizes. That is, the tiling step means dividing the image frame into equal sizes.

As a result, the electronic device 100 can obtain four divided image frames having a resolution of 1920 x 1080, which is the resolution of the storable image.

On the other hand, the electronic device 100 can determine the number of image frames included in one compressed file. The electronic device 100 controls the packaging unit 140 to package a plurality of image frames, which are divided into the same size according to the determined number, according to areas.

For example, when it is determined that four image frames are included in one compressed file through the determination unit 120, the packaging unit 140 stores a plurality of divided image frames, as shown in FIG. 3, Each can be packaged.

Specifically, the acquired image 210 is divided into four, and the upper left image is divided into a second divided image 232, a third divided image 233, and a fourth divided image 233 in the clockwise direction, In the case of the image 234, the packaging unit 140 can package the divided images at the same position with respect to the four image frames.

That is, the packaging unit 140 receives the first divided image 231 of the first acquired image, the first divided image 301 of the second acquired image, the first divided image 311 of the third acquired image, The first divided images 321 of the image can be packaged together.

Accordingly, the packaging unit 140 generates four packages including four image frames for each divided position as shown in FIG. The encoding unit 150 may encode each package and store the encode in the storage unit 160. [ That is, since the resolution of images included in all packages is equal to 1920 x 1080, one type of encoding unit 150 can encode and store all the packages.

4 is a diagram illustrating header information according to an embodiment of the present invention.

The electronic device 100 generates header information 400 including information on the number of image frames obtained through the header information generation unit, the number of image frames included in one compressed file, and the number of divided images for the image frame can do.

That is, the header information 400 may include various information about the image frame to be encoded. In particular, the header information 400 may include a number 410 of image frames, a number 420 of image frames included in one compressed file, and a number of divided images 430 for an image frame.

The number 410 of image frames means the total number of image frames for an image acquired through the image acquisition unit 110. [ That is, as shown in FIG. 4, since the Number of image shown in the header information 400 is 4, it can be seen that there are four image frames of the acquired whole image.

In addition, an IDU (Independently Decodable Unit) means the number of image frames included in one compression file. Therefore, since the Number of IDUS in the header information 400 is 4, the number of image frames included in one compressed file is four.

On the other hand, a divided image frame can be defined as a tile. Therefore, the number of tiles frame 430 is 4, which means that one image frame is divided into 4 equal parts.

In addition to the above information, the header information 400 may store information on the lengths of the images that can be stored. That is, as shown in FIG. 4, the Width and Height parts may include information such that the width of the storable image is 1920, and the height is 1080.

The content of the header information 400 described above is merely an example, and the header information may include various information about the stored image frame such as the type of codec, the number of all tiles, and the like.

Meanwhile, FIG. 5 is a flowchart illustrating a method of encoding a plurality of image frames, according to an embodiment of the present invention.

First, the electronic device 100 acquires an image frame (S500). The electronic device 100 may include a photographing unit and may photograph an image through the photographing unit to obtain an image frame. In particular, the photographing section can acquire a plurality of image frames using the continuous photographing mode. At this time, the plurality of image frames may be related images with a very short time difference taken between them.

However, it is only one embodiment to acquire an image frame through the photographing section. The electronic device 100 can acquire an image frame by various methods such as receiving and acquiring an image frame from an external device connected by wired or wireless have.

Then, the electronic device 100 determines the number of image frames included in one compression file and the number of image frames divided (S510). Specifically, one compressed file includes a predetermined number of image frames. For example, in the case of compressing an I-frame, a P-frame, and a B-frame in order to increase compression efficiency, compressing "I-frame, P-frame, P- The number of image frames included in the file is three.

The number of divisions for an image frame means the number of divisions of each image frame by the same size. That is, the resolution of the storable image is preset in the electronic device 100. Accordingly, when the resolution of the image obtained through the image acquisition unit 110 is larger than the resolution of the image that can be stored, the acquired image frame should be divided according to the resolution of the storable image. Therefore, the number of divisions for an image frame means the number of image frames divided by the same size in order to store the image at a constant resolution.

If there are a plurality of acquired image frames (S520-Y), the electronic device 100 divides each of the plurality of image frames into regions having the same size according to the determined number of divisions (S530).

If the resolution of the image that can be stored is preset according to the hardware characteristics of the electronic device 100, if the acquired image frame is larger than the preset resolution, the electronic device 100 can divide the acquired image frame .

In addition, the electronic device 100 may padding the additional area for each of the plurality of image frames, and may divide the padded image frame into areas of equal size.

That is, if the resolution of the image frame is not an integral multiple of the resolution of the image that can be stored, then the electronic device 100 pads the additional area for each image frame so that the resolution of the image frame is an integer multiple of the resolution of the image, can do.

And the electronic device 100 may divide the image frame including the additional area into areas having the same size.

On the other hand, if the image frame in which the padding area is padded is the same as the resolution of the image that can be stored, the electronic device 100 may package, compress and store the image frame including the additional area without dividing the image frame.

In step S540, the electronic device 100 packages a plurality of image frames divided into equal sizes according to the number of image frames included in the determined one compressed file.

For example, if each image frame is divided into two regions, left-frame and right-frame, and the number of image frames included in one compressed file is 3, The left frame of the third frame may be packaged as one, and the right frame of the first frame to the third frame may be packaged as one.

Then, the electronic device 100 compresses and stores the packaged image frame (S550). In particular, the electronic device 100 may encode the packaged image frame in a moving image format such as MPEG.

Meanwhile, FIG. 6 is a flowchart illustrating a method of encoding and decoding an image frame, according to an embodiment of the present invention.

First, the electronic device 100 acquires an image frame (S600). The electronic device 100 may include a photographing unit and may photograph an image through the photographing unit to obtain an image frame. In particular, the photographing section can acquire a plurality of image frames using the continuous photographing mode. At this time, the plurality of image frames may be an associated image with a very small difference in the time taken to photograph each other.

However, it is only one embodiment to acquire an image frame through the photographing section. The electronic device 100 can acquire an image frame by various methods such as receiving and acquiring an image frame from an external device connected by wired or wireless have.

Then, the electronic device 100 determines the number of image frames included in one compression file and the number of image frames to be divided (S610). Specifically, one compressed file includes a predetermined number of image frames. For example, in the case of compressing an I-frame, a P-frame, and a B-frame in order to increase compression efficiency, compressing "I-frame, P-frame, P- The number of image frames included in the file is three.

The number of divisions for an image frame means the number of divisions of each image frame by the same size. That is, the resolution of the storable image is preset in the electronic device 100. Accordingly, when the resolution of the image obtained through the image acquisition unit 110 is larger than the resolution of the image that can be stored, the acquired image frame should be divided according to the resolution of the storable image. Therefore, the number of divisions for an image frame means the number of image frames divided by the same size in order to store the image at a constant resolution.

If there are a plurality of acquired image frames (S620-Y), the electronic device 100 divides each of the plurality of image frames into regions having the same size according to the determined number of divisions (S630).

If the resolution of the image that can be stored is preset according to the hardware characteristics of the electronic device 100, if the acquired image frame is larger than the preset resolution, the electronic device 100 can divide the acquired image frame .

Further, it is possible to padding the additional area for each of the plurality of image frames, and to divide the padded image frame into the same size area.

That is, if the resolution of the image frame is not an integral multiple of the resolution of the image that can be stored, then the electronic device 100 pads the additional area for each image frame so that the resolution of the image frame is an integer multiple of the resolution of the image, can do.

And the electronic device 100 may divide the image frame including the additional area into areas having the same size.

On the other hand, if the image frame in which the padding area is padded is the same as the resolution of the image that can be stored, the electronic device 100 may package, compress and store the image frame including the additional area without dividing the image frame.

In step S640, the electronic device 100 packages a plurality of image frames divided in the same size according to the number of image frames included in the determined one compressed file.

For example, if each image frame is divided into two regions, left-frame and right-frame, and the number of image frames included in one compressed file is 3, The left frame of the third frame may be packaged as one, and the right frame of the first frame to the third frame may be packaged as one.

In operation S650, the electronic device 100 generates header information including information on the number of the acquired image frames, the number of image frames included in one compressed file, and the number of divided image frames. The header information is information including various information about an image frame to be encoded and decoded. Therefore, it may include various pieces of information about the image frame other than information on the number of the acquired plurality of image frames, the number of image frames included in one compressed file, and the number of divided images for the image frame.

Meanwhile, the electronic device 100 generates packaged image frames, compresses them together with header information, and stores them (S660). In addition to the header information, the electronic device 100 may compress and store a plurality of thumbnail images corresponding to a plurality of image frames.

When the user command for displaying the image frame is input (S670-Y), the electronic device 100 analyzes the header information included in the packaged image frame (S680). Then, the electronic device 100 decodes the compressed file according to the analysis result, and merges the divided regions into one image (S690).

That is, the electronic device 100 can determine, through the header information, the number of frames included in the compressed file as the image frame to be displayed by the user. Specifically, the header information includes information on the total number of image frames and the number of image frames included in one compressed file, so that the electronic device 100 analyzes the header information, It is possible to determine which frame is included in the compressed file.

When judging the compressed file to be decoded, the electronic device 100 decodes the compressed file necessary for displaying the image. That is, when the image frame is divided into four equal parts and is encapsulated and packaged, the electronic device 100 can determine four packages according to the header information analysis result and perform decoding on the four packages.

Then, the electronic device 100 merges the decoded first through fourth divided areas in the four packages, and displays the merged image frame (S700).

On the other hand, if the encoded image frame is decoded and the padded sub-area is included, the electronic device 100 merges the decoded first through fourth divided areas, deletes the added area, and displays the image frame .

With the electronic device 100 as described above, the user can efficiently store a plurality of images regardless of the resolution of the acquired image.

In addition, the user can store the image at a uniform resolution using a method of padding the additional area or dividing the image frame into a predetermined number irrespective of the resolution of various images.

The image processing method of an electronic device according to various embodiments described above may be software-coded and stored in a non-transitory readable medium. Such non-transiently readable media can be used in various devices.

A non-transitory readable medium is a medium that stores data for a short period of time, such as a register, cache, memory, etc., but semi-permanently stores data and is readable by the apparatus. Specifically, it may be a CD, a DVD, a hard disk, a Blu-ray disk, a USB, a memory card, a ROM, or the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
