Document Type and Number:
Japanese Patent JP7118818
Kind Code:
B2
Abstract:
To restrain creation of such image data looking as if a region where blurring occurs and a region where blurring does not occur appears, when cyclic NR processing is applied.SOLUTION: A motion amount detection circuit detects a motion amount from captured image data. A blur amount calculation circuit calculates the blur amount of an imaging apparatus which captured the image data. A strength determination circuit sets the strength of cyclic NR processing. A cyclic NR processing circuit performs cyclic NR processing for the image data with a set strength. A blur correction circuit performs blur correction processing for suppressing blur of the image data subjected to cyclic NR processing, on the basis of the blur amount. When blur correction processing is not operating, the strength determination circuit controls strength of cyclic NR processing in units of region including one or more pixels, on the basis of the motion amount, and when blur correction processing is operating, performs strength control of uniform cyclic noise reduction processing for all region of the image data.SELECTED DRAWING: Figure 1
