Abstract
(EN)
An image processing device includes: a filter processing circuit for performing filter processing on the image data captured by an imaging device by using a plurality of spatial filters; a brightness calculation circuit for calculating the brightness in the local area of the image data; a weighting circuit for weighting an output of the filter processing circuit according to the output of the filter processing circuit and/or the brightness calculation circuit; and an inverse filter processing circuit for performing inverse filter processing for generating processed image data for the output of the weighting circuit.
