    Abstract: 透過影片的亮度平均修正後,拉近了影片中各圖像的亮度值,進而消弭亮度高低差異,因此影片閃爍的現象即可消除,而亮度值皆在調整後針對影片中各個影像進行細部的微調,調整圖像中亮度對比,使圖像中細部的顏色呈現一個協調的色彩。
    After luminance fixed in image and video, luminance in image and video can be similar. Removed luminance difference, then we can see the clearly image with accordant luminance. And we can detail adjust intensity in video or frames, then we can show the modify intensity value in our experiment. After inpaint the intensity in image or video, the image will display the new intensity. We can see the image different and better than original intensity. We maybe also adjust intensity contrast, make sure the detail color and luminance appear same coordinate color. In this issue, we try to use average intensity to solve luminance in video, permeate the frames average intensity we can calculate the middle intensity then we can get the threshold help us to fix the image intensity. And we can use histogram and tensor voting to solve luminance difference in image. We will show the experiment in this research. Then, we will compare these two methods, the result in histogram and tensor voting.
