The device and the manner which the feathering treat the mat image which is in the midst of composite representing choice

摘要

(57) Abstract 1st image (24) of composite image (38) and the feathering to treat feature and manner in order 2nd image (22) include the fact that original mat image (32) is decided. One part of original mat image box filtering being done in horizontal direction and the vertical, intermediate mat image is generated. At least one part of intermediate mat image box filtering being done in horizontal direction and the vertical, treatment end mat image is generated. Edge bias function is applied to treatment end mat image. Edge bias furthermore includes the fact that pixel value of the edge is adjusted with the contrast of mat image and alteration brightness. The composite image which includes 1st and 2nd image generates after applying edge bias function to the treatment end mat image which box filtering is done.
