A method for removing noise of an image. The method includes: (a) detecting a horizontal edge by applying a horizontal edge detection filter to a predetermined pixel field including a notice pixel and neighboring pixel in a vertical direction in image data; (b) judging whether horizontal line noise exists in the predetermined pixel field through the horizontal edge; (c) calculating the number of pixels determined as the horizontal line noise for each horizontal line of the image data by applying steps (a) and (b) to all horizontal lines of the image data; and (d) removing the horizontal line noise by applying a low pass filter to the horizontal line judged to have the horizontal line noise according to the calculation result of step (c).

The present invention relates to an image processing device and a method for processing an image. The image processing device includes a brightness improvement unit to improve a brightness of inputted images by increasing a brightness of a dark image more darker than a knee point among inputted images with reference to a predetermined knee point and decreasing a brightness of an image more brighter than the knee point; and a contrast improvement unit to improve a contrast of the image outputted from the brightness improvement unit. The image processing device and the method for processing the image can reduce a distortion phenomenon and a saturation phenomenon or the like by reflecting the characteristics of images during the brightness improvement and contrast improvement of the images.

There is provided an apparatus for processing an on-screen display (OSD), the apparatus including: a buffer unit receiving first dynamic guideline image information, a color determining unit determining colors for previously divided sections included in the first dynamic guideline image information from the buffering unit, and an image synthesizing unit synthesizing second dynamic guideline image information having the colors for each of the sections, determined by the color determining unit with an image from a camera. With the apparatus for processing an OSD, a user freely sets colors of a warning message, a static guideline, and a dynamic guideline, whereby the warning message, the static guideline, and the dynamic guideline can be displayed on a screen without obscuring a rearview image. In addition, a dynamic guideline can be set as different colors according to sections divided into distances from the rear of a vehicle and an image can be continuously displayed. Further, the camera module can be reprogrammed.
