Problems solved by technology

Therefore, when the face outline storage unit 120 is mounted on a device such as a mobile phone, the size of the device is inevitably increased.
[0023] Also, since the image signal should be compared one by one with the face contours stored in the face contour sample data, it takes a long time to detect the face contour

Abstract

The present invention provides a skin detection system comprising a first skin region detection unit that detects a region included in the first skin region from an externally applied image signal, the first skin region being sampled by a distribution representation of human skin; a second skin area detection unit that detects, from the image signal, an area included in the second skin area in which a human skin area is set; and a skin area processing unit that, when detecting When reaching a region included in both the first and second skin regions, the skin region processing unit determines the region as a human skin region to extract the detected skin region.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2006-0111659 filed with the Korean Intellectual Property Office on November 13, 2006, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a skin detection system and method that detects a human skin area included in an image signal by using a YCbCr color space. Background technique [0004] With the rapid development of digital cameras and mobile phones, a person transmits his / her still or moving images captured by the digital camera or mobile phone to another person through wireless communication. [0005] In this case, a figure (figure) of a person can be included in a still or moving image. However, when the skin color of a person varies in an image, the image quality of the image is significantly degraded. Also, when degradation of image quality occurs in cameras used for airpo...
