Abstract

Methods and systems are disclosed for calibrating image capturing for use in beauty analysis. One of the methods may involve instructing a subject to place a body part adjacent a reference image and capturing a calibrating image of the body part adjacent the reference image using an image capture device. The method also may also involve generating calibration information by processing the calibrating image and information reflective of the reference image, and then calibrating the image capture device and/or a driver for the image capture device using the calibration information.
