Abstract

An image processing system, and a method of operation thereof, includes: a local patch ternarization module for receiving an input image, for calculating a mean value of a local patch of pixels in the input image, and for calculating ternary values for the pixels based on the mean value; and an artifact removal module, coupled to the local patch ternarization module, for removing a residue artifact based on the ternary values and for generating an output image with the residue artifact removed for sending to an image signal processing hardware.

First claim

What is claimed is:

1. A method of operation of an image processing system comprising:
receiving an input image;
calculating a mean value of a local patch of pixels in the input image;
calculating ternary values for the pixels based on the mean value;
removing a residue artifact based on the ternary values; and
generating an output image with the residue artifact removed for sending to an image signal processing hardware.

2. The method as claimed in…
