The system for detecting a face pattern from an input image includes a window extraction unit, a cost calculation unit, and a face pattern discrimination unit. The window extraction unit receives a pre-processed image corresponding to the input image to scan the preprocessed image in a certain window size, and parallelly outputs pre-processing coefficient values corresponding to the scanned pre-processed image. The cost calculation unit parallelly receives the pre-processing coefficient values corresponding to the window size, calculates cost values corresponding to the pre-processed coefficient values, and sums the cost values. The face pattern discrimination unit compares the sum of the cost values with a preset threshold value and discriminates if the pre-processed image corresponding to the window size is the face pattern.
