Biometric image processing apparatus, biometric image processing method, and biometric image processing program

A biometric image processing method comprising:

• first calculating an amount of movement of a living body that moves on a touch panel while coming into contact with the touch panel;
• second calculating an amount of movement of each region in images captured by an biometric sensor in a period in which the living body moves on the touch panel while coming into contact with the touch panel;
• and
• detecting image noise in the captured images based on the respective amounts of movement calculated by the first calculating and the second calculating.

A non-transitory computer-readable storage medium storing a biometric image processing program configured to cause a computer to perform a process comprising:

• first calculating an amount of movement of a living body that moves on a touch panel while coming into contact with the touch panel;
• second calculating an amount of movement of each region in images captured by an biometric sensor in a period in which the living body moves on the touch panel while coming into contact with the touch panel;
• and
• detecting image noise in the captured images based on the respective amounts of movement calculated by the first calculating and the second calculating.
