Abstract
When the illumination changes from the indoor light to the sun light on the location photography by the television, the color temperature changes and the color balance of the photography picture collapses mainly. In the past, we mechanically set a camera with the color temperature revision filter which is made of colored glass or electrically collect using the color collector on the side of the camera. However, these metiod are not so good way. So, we designed and made the filter which is made of liquid device that we can control color temeprature fast and smooth.
