The present invention may provide a device and a method for recognizing a face and stress, the device comprising: a facial area extraction unit which receives an input image including the face of a person subjected to face and stress recognition, and extracts a facial area from the input image according to a pre-learned pattern estimating scheme; a facial feature extraction unit which receives the extracted facial area, and extracts a facial feature according to a pre-learned pattern estimating scheme; a facial recognition unit which compares the extracted facial feature with at least one pre-stored user facial feature and searches for a matched facial feature to perform a face authorization; and a stress recognition unit which classifies the extracted facial feature according to a pre-learned pattern classifying scheme to determine a stress level. Therefore, facial recognition and stress recognition can be performed together at a high speed even in a low-performance device.
