Image processing device, image processing method, and program for detecting and correcting defective pixel in image

摘要

An image processing device includes a texture direction determining unit that determines a texture direction of an image, a defective pixel detecting unit that calculates a pixel value average for each of pixel groups including a plurality of pixels, and detects a defective pixel position on the basis of difference information of the pixel value average according to an arrangement direction of the pixel groups, and a correction unit that corrects, as a correction target, a pixel value at the defective pixel position detected on the basis of the difference information in the same pixel group arrangement direction as the texture direction determined by the texture direction determining unit.

主权项

1. An image processing system, comprising:
circuitry configured to:
acquire an image;determine a texture direction of the image;detect a defective pixel position based on difference information relating to differences between pixel value averages of respective pixel groups of the image, wherein each of the pixel groups include a plurality of pixels and also has associated therewith a respective pixel value average that is determined based on pixels within the respective pixel group; andcorrect a pixel value at the defective pixel position based on the texture direction and the difference information.
