Camera apparatus and method for removing image noise |
摘要 |
Disclosed is a method of removing image noise of a camera having an illumination sensor. The method includes: grasping the noise response characteristics of the camera and storing mean signal-to-noise ratio values for respective illumination values in a low frequency region and a high frequency region; acquiring the present illumination value using the illumination sensor when photographing an image; reading mean signal-to-noise ratio values of the low frequency region and the high frequency region corresponding to the present illumination value from the stored mean signal-to-noise ratio values; and applying the read mean signal-to-noise values to filters for respective frequency regions, thereby filtering the signals of the photographed image.
