Claim 15:
16. An image processing system comprising:
an red-green-blue (RGB) camera;
a time of flight (ToF) camera; and
an image processing device,
wherein the image processing device includes:
an red-green-blue (RGB) image acquisitor configured to acquire a first RGB image from the RGB camera;
an RGB image pre-processor configured to extract a reflection component from the first RGB image;
a time of flight (ToF) image acquisitor configured to acquire a ToF infrared ray (IR) image from the ToF camera; and
an image processor configured to acquire 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 RGB image pre-processor converts the first RGB image into a first hue-saturation-value (HSV) image and then acquires the reflection component from a value component of the first HSV image.
