摘要：
An image processing device separates an original image signal into a plurality of components including a first component serving as a skeleton component and a second component obtained after the first component is separated from the original image signal, obtains a signal level of the first component or the original image signal, sets a tone conversion coefficient to be applied during tone conversion based on the signal level of the first component or the original image signal, performs tone conversion processing on the first component using the tone conversion coefficient, obtains the signal level of the first component, sets a noise reduction processing parameter on the basis of the signal level of the first component, and reduces a noise of the second component using the noise reduction processing parameter and the tone conversion coefficient.
