At this time, the control module 130 divides the representative image into a plurality of areas. If the saturation value of each divided area of the representative image is equal to or greater than the reference value, the control module 130 recognizes the black area. Accordingly, the control module 130 calculates the black-and-white ratio (B / W ratio), which is the area ratio occupied by the black area and the white area of the representative image. For example, the black and white ratio of a particular image may be 70:30.

Then, in step S240, the controller 270 converts the captured image into grayscale to calculate the black-and-white ratio. More specifically, a method of calculating the black-and-white ratio will be described as follows. First, the control unit 270 converts the shot image into grayscale. Then, the controller 270 sets the average value of the saturation values of the photographed image as the reference value. The controller 270 divides the photographed image into a plurality of areas, recognizes the image as a black area if the saturation value of each divided area of the photographed image is equal to or greater than the reference value, and recognizes the area as a white area if the saturation value is below the reference value. Accordingly, the control unit 270 can calculate the black-and-white ratio of the photographed image, which is the area ratio occupied by the black region and the white region of the photographed image.

Next, the control unit 270 waits for execution of a plurality of candidate videos based on the black-and-white ratio in step S250. In other words, the control unit 270 compares the black-and-white ratio of the photographed image with the black-and-white ratio of the representative image among the header information of the compiling file to obtain a representative image having a monochrome ratio within a predetermined range The mapped video is run as a candidate video.

The controller 270 derives the feature value of the captured image and the feature value of the representative image matched to each of the candidate moving image files waiting to be executed in step S260. Here, the controller 270 determines whether the background image is black or white, and the background image is black or white, and the background image is black, It is possible to display a plurality of division points by repeating the operation of displaying the division points, and to derive a plurality of division points displayed as a feature value by repetition.

Hereinafter, a method of deriving a feature value of an image including a representative image and a captured image according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 7 and 8. FIG. Referring to FIG. 7, the controller 270 converts the image into gray scale in step S310. Then, in step S320, the controller 270 sets a portion having a black ratio of 70% or more as a black region, and a portion having a black ratio of less than 70% as a non-black region. In step S330, the controller 270 divides the black region of the image and the non-black region, and sets a dividing point at the boundary. If the black area is wide based on the boundary in step S340, the controller 270 specifies the area as a background, and designates an area that is not a background as an object. Then, in step S350, the controller 270 divides the black region of the image and the non-black region in the object region, and sets the division point at the boundary. The controller 270 determines whether there is an area to be further classified in step S360. As a result of the determination in step S360, if there is an area to be further classified, steps S340 to S360 are repeated. As a result of the determination in step S360, if there is no area to be further classified, the process proceeds to step S370 to derive all the divided points as feature values. According to the above-described method, it is possible to derive a plurality of division points indicated by a cross in Fig. 8 (B) from the image as shown in Fig. 8 (A) as feature values.

Referring back to FIG. 6, after extracting the feature values of the representative image and the captured image as described above, the controller 270 compares the extracted feature values of the plurality of candidate videos (S260) in step S270, And a candidate video mapped to the representative image having a similarity value equal to or greater than a predetermined value. Then, the control unit 270 automatically executes the candidate video selected in step S280 and displays it on the display unit 250. [

As described above, according to the present invention, a moving image having a black-and-white ratio within a predetermined range among all moving images stored in the user device 200 is queued as a candidate moving image, and one moving image is selected through the characteristic value. Therefore, the present invention does not perform a process of deriving a feature value for all moving images stored in the user device 200, but performs a process of deriving a feature value only for a part of the candidate moving image. Thus, resources of the user apparatus 200 used in the process of selecting a moving picture are saved. Moreover, the processing speed of the process of selecting a moving picture can be improved, and overload can be prevented.

Meanwhile, the access control method according to the embodiment of the present invention described above can be implemented in a form of a program readable by various computer means and recorded in a computer-readable recording medium. Here, the recording medium may include program commands, data files, data structures, and the like, alone or in combination. Program instructions to be recorded on a recording medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of computer software. For example, the recording medium may be a magnetic medium such as a hard disk, a floppy disk and a magnetic tape, an optical medium such as a CD-ROM or a DVD, a magneto-optical medium such as a floppy disk magneto-optical media, and hardware devices that are specially configured to store and execute program instructions such as ROM, RAM, flash memory, and the like. Examples of program instructions may include machine language wires such as those produced by a compiler, as well as high-level language wires that may be executed by a computer using an interpreter or the like. Such a hardware device may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.

While the present invention has been described with reference to several preferred embodiments, these embodiments are illustrative and not restrictive. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention and the scope of the appended claims.
