Image receiving device image reconstructing method thereof method for image masking and reconstructing of image system

摘要

The present invention discloses an image masking and restoration method of an imaging system for protecting personal privacy. The image restoration method of the image receiving apparatus according to an embodiment of the present invention comprises the steps of restoring the masking image data by decoding the first data encoding the blinded masking image data from the original image data and the privacy region image data. ; Selectively decrypting second data, which is encrypted image data of the plurality of privacy zones, in response to a selection signal of at least one privacy zone of the plurality of privacy zones; And synthesizing the reconstructed masking image data and the decoded image data of at least one privacy region to generate an output image in which the blinds of the at least one privacy region are selectively released.
