Abstract
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.
Claims26
An image processor for executing an image processing of image data picked up by image pickup means, comprising:
- filter process means for filtering the image data with a plurality of spatial filters;
- brightness calculation means for calculating a brightness in a local area of the image data;
- weighting means for weighting an output of the filter process means in accordance with an output of the filter process means and/or an output of the brightness calculation means;
- and
- inverse filter process means for executing an inverse filtering with respect to an output of the weighting means to generate process image data.
An endoscope apparatus comprising:
- an endoscope equipped with image pickup means;
- filter process means for filtering of image data picked up by the image pickup means, to which a plurality of filters are applied;
- brightness calculation means for calculating a brightness in a local area of the image data.
- weighting means for weighting an output of the filter process means in accordance with an output of the filter process means and/or an output value of the brightness calculation means;
- and
- inverse filter process means for executing an inverse filtering with respect to an output of the weighting means to obtain process image data.
