Abstract
This image correction system corrects image data from pixels, is connected to at least two different input pathways, and is provided with: a pixel value relationship extraction means that extracts the pixel value relationship among neighboring pixels from image data that is the subject of correction; a pixel value relational expression estimation means that estimates a relational expression representing the difference in characteristics in each pixel from the pixel value relationship between neighboring pixels; and a pixel value correction means that forms a corrected image by correcting the pixel values of the image data that is the subject of correction using the relational expression.
Claims10
An image correction system for correcting image data from pixels connected to at least two different input paths, the image correction system comprising:
- a memory for storing instructions;
- and
- a processor coupled to the memory, the processor configured to execute the instructions thereby implementing:
- an input circuit which inputs image data of a correction target;
- a pixel value relationship extraction circuit which extracts a relationship of pixel values among adjacent pixels from the image data of the correction target;
- a pixel value relational expression estimation circuit which estimates a relational expression representing a characteristic difference at each pixel from the relationship of the pixel values among the adjacent pixels;
- a pixel value correction circuit which generates a correction image by correcting pixel values of the image data of the correction target using the relational expression;
- and
- an output circuit which outputs the correction image.
An image correction method of correcting image data from pixels connected to at least two different input paths, comprising:
- inputting, with one or more input interfaces, image data of a correction target from pixels connected to at least two different-input paths;
- extracting, with one or more processors, a relationship of pixel values among adjacent pixels from the image data of the correction target;
- estimating, with one or more processors, a relational expression representing a characteristic difference at each pixel from the relationship of the pixel values among the adjacent pixels;
- generating, with one or more processors, a correction image by correcting the pixel values of the image data of the correction target using the relational expression;
- and
- outputting, with one or more output interfaces, the correction image.
A non-transitory computer readable medium for recording an image correction program for correcting image data from pixels connected to at least two different input paths, the image correction program causing a computer to execute:
- a process for inputting image data of a correction target;
- a process for extracting a relationship of pixel values among adjacent pixels from the image data of the correction target;
- a process for estimating a relational expression representing a characteristic difference at each pixel from the relationship of the pixel values among the adjacent pixels;
- a process for generating a correction image by correcting the pixel values of the image data of the correction target using the relational expression;
- and a process for outputting the correction image.
