A biometric image processing apparatus includes a touch panel, an biometric sensor configured to capture an image of a living body, and a processor. The processor performs a process including first calculating an amount of movement of the living body that moves on the touch panel while coming into contact with the touch panel, second calculating an amount of movement of each region in images captured by the 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.
