IMAGE PROCESSING UNIT, IMAGE PROCESSING METHOD AND IMAGING DEVICE

摘要

An image processing unit includes a candidate pixel group determiner to specify each pixel of an image to be processed as pixel of interest, extract pixels having divergence in position in a certain range from the pixel of interest, and determine, from the extracted pixels, pixels having divergence in pixel value in a certain range from the pixel of interest as a candidate pixel group, an associator to associate the candidate pixel group with the pixel of interest, and an image processor to perform image processing on the candidate pixel group associated with the pixel of interest. The image processor selects, from the candidate pixel group, pixels having divergence in pixel value in a certain range from the pixel of interest as a pixel group to be processed, and smoothes the pixel value of the pixel of interest in accordance with each pixel value of the candidate pixel group.

1. An image processing unit comprising:
a candidate pixel group determiner configured to specify each pixel of an image to be processed as a pixel of interest, extract pixels having a divergence in position in a certain range from the pixel of interest, and determine, from the extracted pixels, pixels having a divergence in pixel value in a certain range from the pixel of interest as a candidate pixel group; an associator configured to associate the pixels of the candidate pixel group with the pixel of interest; and an image processor configured to perform image processing on the pixels of the candidate pixel group associated with the pixel of interest, wherein: the image processor is configured to select, from the pixels of the candidate pixel group, pixels having a divergence in pixel value in a certain range from the pixel of interest as a pixel group to be processed, and smooth the pixel value of the pixel of interest in accordance with the pixel value of each pixel of the candidate pixel group; the determining of the candidate pixel group determiner is executed for each pixel of interest at once; and the image processing of the image processor is executed for each pixel of interest at a plurality of times.
