Abstract: Disclosed is an image processing method. The image processing method includes forming a reference division line to perform white balance, forming a grid including a pixel distribution degree based on the reference division line, extracting a red gain value, a blue gain value, and the pixel distribution degree with respect to a specific point on the reference division line, determining if the extracted pixel distribution degree is a maximum point, and setting new gain values by using the extracted red gain value and the extracted blue gain value depending on if the pixel distribution degree is the maximum point.

Abstract: Disclosed are a forward collision warning system and a forward collision warning method. The forward collision warning system includes a photographing unit installed at a front of a vehicle to photograph an object in a forward direction of the vehicle; a driving unit that receives image data from the photographing unit to search for a forward candidate vehicle by classifying the image data using a predetermined mask, filters the candidate vehicle to settle an object corresponding to a real vehicle, tracks the object in a plurality of frames in order to add a missed object, and calculates a collision time based on a distance between the object and the vehicle to generate a warning generating signal according to the collision time; and a warning unit to generate a forward collision warning signal based on the warning generating signal received from the driving unit.

Abstract: Disclosed is a method of enhancing contrast of an image by using a Bezier curve. Histogram distribution is calculated based on an image that has been photographed or read out from a storage medium, the type of the image is determined according to the contrast state of the image, the movement directions of control points of a 3-D Bezier curve is determined according to the type of the image, and the movement distances of the control points of the 3-D Bezier curve are calculated based on the number of luminance values of the histogram distribution. Two control points of the 3-D Bezier curve are moved based on the movement directions and the movement distances of the control points, and the 3-D Bezier curve is created by using the two moved control points and two fixed control points. The contrast of the image is enhanced by applying the Bezier curve.
