Image processing device and image processing method

摘要

An image processing device includes a first production part configured to apply a first smoothing process to an original image data by using a first edge-preserving smoothing filter to produce first image data that include a low-frequency image and an edge image, a second production part configured to apply a second smoothing process to a differential image between the original image data and the first image data to produce second image data that include a high-frequency image, and a synthesis part configured to synthesize the first image data and the second image data.

1. An image processing device, comprising:
one or more memories storing instructions; and one or more processors configured to execute the instructions stored in the one or more memories to implement steps of applying a first smoothing process to an original image data by using a first edge-preserving smoothing filter to produce first image data that include a low-frequency image and an edge image; applying a second smoothing process to a differential image between the original image data and the first image data to produce second image data that include a high-frequency image; and synthesizing the first image data and the second image data.
