1. An image masking method of a surveillance system in which a processor and a memory are included and an operation is controlled by the processor, the image masking method comprising:
extracting an object from an image;
obtaining characteristic information of the extracted object by analyzing the extracted object in an image;
designating a specific region in the image based on a user input;
comparing the characteristic information with a database to analyze whether the extracted object is a registered person;
selecting the extracted object as a masking target when the extracted object is not the registered person;
detecting whether the extracted object is positioned in the specific region; and
performing selective masking on the extracted object according to whether the extracted object is positioned in the specific region,
wherein the performing of the selective masking includes:
not performing masking on the extracted object that is positioned outside of the specific region, and
performing the masking on the extracted object when the extracted object enters the specific region.
