Moving image noise reduction apparatus and moving image noise reduction method

A moving image noise reduction apparatus comprising:

• a filter unit that decomposes image data from an image sensor adapted to capture images at a predetermined frame rate into a low-frequency component and a first high-frequency component;
• a motion vector estimation unit that reads data from an event sensor, adapted to asynchronously output information on a pixel in which a brightness changes, at a frame rate higher than the predetermined frame rate and estimates a motion vector;
• and
• a motion compensation unit that performs motion compensation based on the motion vector,
• wherein the filter unit generates a third high-frequency component by adding the first high-frequency component and a second high-frequency component extracted from an image obtained by motion compensation at a predetermined ratio, and reduces a noise in the image data by adding the low-frequency component and the third high-frequency component.
