7. An image processing method of performing image processing on an image of an object shot with flashing of an illumination device, comprising:
determining a position of a virtual light source that emits virtual light, wherein the position is different from a position of the illumination device;
calculating a reflection component of the virtual light reflected by the object based on the shape of the object and the position of the virtual light source determined by the determination unit; and
correcting brightness of an object area in the image so as to reduce a light component that is from the illumination device and reflected by the object and to add the reflection component of the virtual light reflected by the object.
