The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

 As described above, according to the present invention, there are advantages and advantages as will be described later on the user side of the mobile communication terminal and the content provider that provides the content.

On the user side of the mobile communication terminal, when using a mobile communication terminal equipped with a camera function, an image generated by synthesizing an image taken with a camera and a previously downloaded image can be used as image coloring, thereby clearly distinguishing individual characteristics. It has a revealing effect.

The content providing business that provides the image coloring service has an advantage of increasing the average revenue per mobile subscriber because not only the image used for the image coloring but also the image is provided through the image synthesizing server.
