An image taking method that acquires a taken image from a camera capable of taking a predetermined region and uses the acquired taken image as a monitoring image or authentication image, the method comprising:

• determining whether a biometric portion that can be used for biometric authentication of a subject is included in the image taking range of the camera;
• and
• processing the taken image as the authentication image when receiving an authentication image acquisition instruction and alternatively, in the case where there has not issued the authentication image acquisition instruction, when it is determined that a biometric portion is not included in the image taking range of the camera, processing the taken image as the monitoring image and when it is determined that a biometric portion is included in the image taking range of the camera, stopping image taking operation of the camera.

A computer-readable medium having recorded thereon an image taking program allowing a computer to execute an image taking method that acquires a taken image from a camera capable of taking a predetermined region and uses the acquired taken image as a monitoring image or authentication image, the program allowing the computer to execute a process comprising:

• determining whether a biometric portion that can be used for biometric authentication of a subject is included in the image taking range of the camera;
• and
• processing the taken image as the authentication image when receiving an authentication image acquisition instruction and alternatively, in the case where there has not issued the authentication image acquisition instruction, when it is determined that a biometric portion is not included in the image taking range of the camera, processing the taken image as the monitoring image and when it is determined that a biometric portion is included in the image taking range of the camera, stopping image taking operation of the camera.
