Abstract: A method for measuring a non-contact biometric information, includes steps of photographing an image including a user's face; detecting a face area in a frame of a photographed image; detecting a landmark within the face area and starting a tracking mode when a specific landmark is detected; detecting a movement of the face area in the tracking mode and determining a section in which the movement of the face is less than a reference value; and extracting a skin area within the face area in the determined section and acquiring pixel change component data of the skin area.

Abstract: A face image generating method for recognizing face performed by a face image generating device to extract a face image from image frames collected from an image acquiring device and generate a face image for face recognition, includes: a first step of converting an RGB-based image frame received from the image acquiring device into a YCbCr image; a second step of setting a region satisfying a skin color condition in the YCbCr image as a face candidate region; a third step of determining a face region; a fifth step of calculating a degree of inclination of a side face; and a sixth step of generating a face image for recognition by converting the front face image and the side face image into different sizes according to a distance to the image acquiring device.
