摘要： A method for detecting color temperature and an apparatus thereof are disclosed. According to the present invention, the apparatus for detecting color temperature converts RGB color information, generated by interpolating an image signal sequentially inputted in units of pixel from an image sensor, to a three-dimensional coordinate value of luminance, R-G color difference information, and B-G color difference information, and then renews the added value per color, if included in a filtering zone corresponding to a characteristic curve of the image sensor. Then, an average value per color is generated in units of frame, and the compensation rate per color is determined such that the average value per color becomes identical to each other. With the present invention, accurate colors can be displayed by detecting the color temperature of the current light source and correcting the distorted color information.
