This image processing device and image processing method determine the color of the lips in face images imaged under various conditions and determines the region of the lips using the determined color of the lips. This image processing device (6), which determines characteristics of the lips from a face image containing a person's mouth, is provided with: a representative skin color determination unit (17) for determining a representative color of the skin in a face image; a candidate color determination unit (18) which sets multiple regions in the face image such that least one of said regions contains a part of the lips, and determines a representative color of each region as a candidate color; and a representative lip color determination unit (19) which determines a representative color of the lips from the multiple candidate colors depending on the difference in hue and color saturation between the representative color of the skin and the candidate colors.
