Edge detecting method
First Claim
1. An edge detecting method comprising the steps of:
- a) setting a first kernel based on a center pixel in pixel data arranged in a mosaic structure;
b) setting a second kernel based on the center pixel within the first kernel;
c) detecting whether a pixel having a green value in the second kernel is a defective pixel, and correcting the pixel;
d) converting all pixels of the second kernel into pixels having green value;
e) calculating a slope value by using a mask for detecting an edge in the second kernel; and
f) detecting an edge by adding the slope value to a luminance value obtained by a color space conversion.

Abstract
There is provided an edge detecting method, which is capable of preventing a noise influence caused by imaging device and a color interpolation. The edge detecting method includes the steps of: setting a first kernel based on a center pixel in pixel data arranged in a mosaic structure; setting a second kernel based on the center pixel within the first kernel; detecting whether a pixel having a green value in the second kernel is a defective pixel, and correcting the pixel; converting all pixels of the second kernel into pixels having green value; calculating a slope value by using a mask for detecting an edge in the second kernel; and detecting an edge by adding the slope value to a luminance value obtained by a color space conversion.
