Patent ID: 8724920

Claim:
An image processing device comprising: a component separation section configured to separate an original image signal into a plurality of components including (i) a first component that is a framework component of the original image signal, the first component containing a slowly fluctuating component and an edge component, and (ii) a second component that is a residual component corresponding to the original image signal from which the first component has been excluded, the second component containing a texture component and a fluctuation component, and the fluctuation component representing noise; an edge information acquisition section configured to obtain edge information from the first component; a fluctuation-component reduction section configured to reduce the fluctuation component of at least the second component, and to output a corrected second component; a parameter acquisition section configured to acquire a parameter for the fluctuation-component reduction section based on the edge information obtained by the edge information acquisition section; and a component synthesis section configured to synthesize the first component and the corrected second component; wherein the first component is one of (i) a low-order component resulting from orthogonal basis expansion of the original image signal, and (ii) a result of application of a Bilateral Filter to the original image signal.
