1. An image processing method of an image processing device, comprising:
acquiring a first red-green-blue (RGB) image using an RGB camera;
extracting a reflection component from the first RGB image;
acquiring a time of flight (ToF) infrared ray (IR) image using a ToF camera; and
acquiring a second RGB image by adding the reflection component of the first RGB image and the ToF IR image,
wherein the ToF IR image is an amplitude image or an intensity image generated from IR images for four phases, and
wherein the extracting of the reflection component includes:
converting the first RGB image into a first hue-saturation-value (HSV) image; and
acquiring the reflection component from a value component of the first HSV image.
