Abstract
A face authentication method for a computer to execute a process includes acquiring a plurality of images from a camera; acquiring a contour change degree that represents a difference between a first contour included in an image imaged in a first image and a second contour included in the face image imaged in a second image, the plurality of images including the first image and the second image; acquiring a reflection change degree that represents a difference between first light reflection characteristic of the first image and second light reflection characteristic of the second image; and determining whether imaging targets of the camera has switched, based on the contour change degree and the reflection change degree.
