PURPOSE: A biological information processing system is provided to judge whether the detection of characteristic points are proper or not and to confirm whether the quality for a comparison process is proper or not. CONSTITUTION: A biological information processing system (100) comprises an input unit (101), a parameter setup unit (102), a face detection unit (103), a facial feature extraction unit (104), a feature information judgment unit (105), a correction unit (106), an output unit (107), and a similarity judgment unit (108); and is connected to a camera (150). The biological information processing system extracts the facial feature information by using image data which are input from the camera, and registers the facial feature information in a database of the facial feature information for comparison. The face detection unit extracts a face area which displays a figure from the input information. The facial feature extraction unit extracts the feature information from the extracted facial area based on the characteristic part of the figure. The feature information judgment unit judges whether the characteristic area of the figure for the extracted feature information is extracted or not.
