Abstract:
1. An image processing apparatus comprising: a low-frequency component extraction unit for extracting a first low-frequency component from first image data; a noise reduction unit for obtaining a second low-frequency component by applying a noise reduction filter to either the first low-frequency component or data obtained by processing the first low-frequency component; a high-frequency component extraction unit for extracting a first high-frequency component from the first images data and either one of the second low-frequency component and data obtained by processing the second low-frequency component, and the first image data; a high-frequency component tuning unit for obtaining a second high-frequency component by tuning the first high-frequency component to reduce amplitude of the first high-frequency component; and an image synthesis unit for obtaining second image data by combining either one of the second low-frequency component and the data obtained by processing the second low-frequency component with the second high-frequency component.
