Image-monitoring device and method for detecting events therefor

An event detecting method of an image monitoring device, the method comprising:

• setting first and second monitoring events related to a monitored image;
• obtaining a monitored image;
• detecting an occurrence of a first monitoring event with respect to an object from the obtained monitored image;
• detecting an occurrence of a second monitoring event with respect to the object from the obtained monitored image when the first monitoring event occurs;
• and
• storing information regarding the detected occurrence of the second monitoring event,
• wherein the setting the first and second monitoring events comprises:
• setting at least one of a position in which a first region corresponding to the first monitoring event is set, a size of the first region, and a shape of the first region based on a user input, wherein the first monitoring event occurs within the first region;
• setting at least one of a position in which a second region corresponding to the second monitoring event is set, a size of the second region, and a shape of the second region based on a user input, wherein the second monitoring event occurs within the second region;
• inputting sequence information with respect to the first and second monitoring events;
• determining the first and second monitoring events based on the sequence information;
• and
• setting a duration time between the first and second monitoring events,
• wherein the information is stored only if the occurrence of the second monitoring event is detected after a lapse of the duration time from the occurrence of the first monitoring event.
