Zusammenfassung: | The invention discloses a wide dynamic processing method based on a visual system. The method comprises steps of: acquiring a single image of a specific scene; transforming the single image from a RGB color space to a YUV color space and acquiring brightness information Y component; computing the environmental factor of each pixel by using the pixel neighborhood information of the Y component; and according to the characteristic of the human visual system, transforming the original RGB image by using a wide dynamic transformation formula acquired by the environmental factors so as to obtain a wide dynamic RGB image. The wide dynamic processing method based on the visual system well keeps detailed information of a bright area and a dark area, has good wide dynamic image quality, consumes few resources, and well satisfies a requirement of real-time processing. |
