Claim Text:
1. A system for compensating for image blur, the system comprising: a movement detector configured to detect an appearance of a subject moving in a surveillance range in a direction horizontal to a display of a camera in order to calculate movement characteristics of the subject on the display of the camera which obtains an image of the object; a calculator configured to determine moving characteristics of an image sensor provided inside a body of the camera in proportion to the movement characteristics of the subject; and a moving unit configured to move the image sensor independently from the body of the camera for an exposure time of at least one predetermined frame based on the moving characteristics of the image sensor, wherein the movement characteristics of the subject comprise a movement distance and speed of the subject on the display, and wherein the moving characteristics of the image sensor comprise a moving distance and speed of the image sensor with respect to a direction of a lens of the camera within the camera, wherein the moving unit is further configured to move the image sensor with respect to the direction of the lens of the camera within the camera for the exposure time of the predetermined frame while the lens of the camera is directed to a fixed direction so that a given pixel of the image sensor outputs an image of a same portion of the subject regardless of the moving of the subject in a surveillance region.
