1. An image processing device, comprising:
a three-dimensional noise reduction (3D NR) circuit, performing a 3D NR operation on input image data to generate first image data;
an artificial intelligence noise reduction (AI NR) circuit, performing an AI NR operation on the input image data to generate second image data;
a weight determination circuit, outputting a blending weight according to a motion index; and
a first image blending circuit, blending the first image data and the second image data according to the blending weight to generate output image data.
