A method for abstracting a HSV histogram from an input image saved YCbCr in a YCbCr model is disclosed, which includes a) forming a LUT divided into a plurality of sections which can print out a quantified index value by receiving an input YCbCr and in which the quantified index value of each section is saved, b) selecting one section from the LUT according to a Y signal or a CbCr signal of the input YCbCr model, and c) abstracting the histogram using the index of the selected section. Thus, the speed of abstracting the histogram can be increased hundreds or thousands times as fast as a related art by omitting processes of converting the image saved in the YCbCr model to the HSV model and of quantifying the YCbCr model.
