Abstract

An image processing method for an image processing device according to an embodiment of the present invention comprises the steps of: obtaining a first RGB image by means of an RGB camera; extracting a reflection component from the first RGB image; obtaining a TOF IR image by means of a TOF camera; and obtaining a second RGB image by calculating the reflection component of the first RGB image and the TOF IR image, wherein the TOF IR image is an amplitude or intensity image generated from an IR image with respect to four phases.

Description

technical field [0001] The present invention relates to an image processing device and image processing method using a red-green-blue (RGB) camera and a time-of-flight (ToF) camera. Background technique [0002] Red-green-blue (RGB) cameras commonly installed on mobile devices have the problem of low image quality due to extremely low brightness or high noise when capturing images in low-light environments. As a method of improving the image quality of an RGB camera in a low-light environment, a flash function can be used. However, when using the flash function, it may be difficult to obtain a natural image due to light saturation at a short distance from firing the flash. As another way to improve the image quality of RGB cameras in low-light environments, infrared (IR) sensors can be used with RGB cameras. However, the sensitivity of RGB colors may be reduced due to the infrared sensor. [0003] Therefore, there is a need for new methods of improving the image quality o...
