    • The present invention is to provide an image processing system and a method thereof implemented to a series of images in a video film of an outdoor scene, which includes: defining types of free-falling objects (such as raindrops, snowflakes or hailstones) related to natural weather; reading information of a selected type of the free-falling objects so as to randomly generate falling positions and vertical falling textures of the free-falling objects in each image; detecting a grayscale value of the image, and defining a certain region of the image where the grayscale value exceeds a predetermined grayscale value as a deposited region; simulating a deposited status of the free-falling objects in each deposited region; and integrating the vertical falling texture and the deposited status into the video film for simulating the free-falling objects in the images, so as to produce effects approximating real effects of natural weather in the video film.
    • 本发明提供一种对户外场景的影像中的一系列图像实施的图像处理系统及其方法,其特征在于,包括:定义与自然落下的物体(例如雨滴,雪花或冰雹)有关的类型 自然天气 读取所选择的自由落体物体的信息,以随机地生成每个图像中的自由落体物体的下降位置和垂直落下的纹理; 检测图像的灰度值,并且将灰度值超过预定灰度值的图像的特定区域定义为沉积区域; 模拟每个沉积区域中自由落体物体的沉积状态; 并将垂直下落纹理和沉积状态整合到视频胶片中,以模拟图像中的自由落体物体,从而产生逼近视频胶片中自然天气的实际效果的效果。
