APPARATUS AND SYSTEM FOR IMPROVING IMAGE QUALITY

摘要

A system and an apparatus for improving image quality of an object (140) in video telephony are described. The apparatus comprises an image detection unit (210), an image alignment unit (220) and an image fusion unit (230). A near infrared light source (240) in the image detection unit (210) illuminates the object (140), such that the object (140) is front illuminated. An image sensor (250) alongside the near infrared light source (240) generates a near infrared image and a visible image. An image alignment unit (220) aligns the near infrared image and the visible image. An image fusion unit (230) fuses the aligned near infrared image and aligned visible image pair to form a composite image of the object (140). The composite image of the object (140) has improved image quality, image detail, and a reduction in shadows.
