1. An image processing device comprising:
a memory configured to store instructions: and
at least one processor configured to execute the instructions to:
acquire a first image generated by capturing an object by using light at a first wavelength, the first image including a face;
acquire a second image generated by capturing the object by using light at a second wavelength, the second image including the face;
acquire three-dimensional information from the second image;
determine, based on the three-dimensional information acquired from the second image, whether or not the face in the second image is one obtained by capturing a living body; and
perform biometric recognition of the object by using the face in the first image and the three-dimensional information acquired from the second image.
