Self-adaptive image edge correction device and method thereof

摘要

A self-adaptive image edge correction device and method thereof, including an image fetching unit, an image processing unit, and an image output unit. Wherein, the image fetching unit is used to provide an original image, and is connected electrically to the image processing unit, that includes a sharpening filter, a superimposer, and an edge detector. The sharpening filter converts the original image into a sharpened edge image, and the superimposer superimposes the original image to the sharpened edge image, to form an enhanced image. The edge detector fetches the edge of the enhanced image, to obtain a differential edge image. The image processing unit then utilizes selectively the horizontal correction or vertical correction to correct the differential edge image, based on s deviation direction of the differential edge image, to form a corrected image, and provide it to the image output unit to output as required.

1. A self-adaptive image edge correction method, comprising:
inputting an original image; sharpening said original image, to convert said original image into a sharpened edge image; superimposing said original image onto said sharpened edge image, to form an enhanced image; fetching an edge of said enhanced image, to obtain a differential edge image; determining deviation direction of said differential edge image selectively utilizing horizontal correction or vertical correction based on the determined deviation direction of said differential edge image; and correcting said differential edge image based on the selectively utilized horizontal correction or vertical correction to obtain a corrected image.
