An image processor includes a filter process circuit for executing a filtering of image data picked up by an image pickup unit with a plurality of spatial filters, a brightness calculation circuit for calculating a brightness in a local area of the image data, a weighting circuit for weighting an output of the filter process circuit in accordance with an output of the filter process circuit and/or an output of the brightness calculation circuit, and an inverse filter process circuit for executing an inverse filter process with respect to an output of the weighting circuit to generate process image data.
