Title: DEVICE AND METHOD FOR PROCESSING DEPTH IMAGE BY BLURRING
Abstract:
A device and method for processing depth image by blurring. The device comprises: an acquisition module, configured to acquire an aperture value, a focal distance, a focusing distance and a permissible circle of confusion diameter; a calculation module, configured to calculate the scope of a depth of field according to the acquired aperture value, the focal distance, the focusing distance and the permissible circle of confusion diameter; a determination module, configured to acquire object distances of focusing points, and determine blurring degrees corresponding to the different object distances according to the obtained object distances of the focusing points, the aperture value and the focal distance; a correction module, configured to correct a radius corresponding to Gaussian blur according to the blurring degrees corresponding to the determined different object distances; and a blur processing module, configured to perform, according to the corrected radius corresponding to the Gaussian blur, blur processing on pixel points of depth image that is located outside the scope of the depth of field and is needed to be processed and shoot. After the technical solution is adopted, a shooting effect is improved while not changing a structure of physical hardware of a related mobile terminal.
