METHOD FOR OPTIMIZING PRIVACY MASK OF CAMERA OF WHICH PANNING AND TILTING ARE CONTROLLED, AND IMAGING DEVICE TO WHICH PRIVACY MASK OPTIMIZATION IS APPLIED

摘要

The present invention relates to a method for correcting the location of a privacy mask, and a method for performing panning or tilting, and performing masking by using a privacy mask for an image captured by an imaging device in which the rotation axis of an imaging unit and the center of a lens do not correspond comprises the steps of: generating a mask for an object under a first imaging condition; and performing masking for the object under a second imaging condition by correcting a mask location error that occurs when applying, to the second imaging condition, the mask generated under the first imaging condition, wherein the first imaging condition is the same as the second imaging condition with respect to the imaging angle of the lens, and is reversed with the second imaging condition around the rotation axis with respect to the location of the lens, and the mask location error occurs because of the location difference of the imaging device under the first imaging condition and the second imaging condition, thereby allowing a flip and enabling normal masking during the flip in the imaging device, in which the rotation axis of the camera and the center of the lens do not correspond.
