1. A device for skin detection comprising:
- an illumination unit configured to project a predetermined illumination pattern onto a scene;
an imaging unit configured to acquire an image of the scene;
an evaluation unit configured to evaluate the acquired image by analyzing blur of edges of the imaged illumination pattern as reproduced in the image and detecting skin areas within the image based on the analysis of the blur of the edges and distinguishing the skin areas from non-skin areas within the image based on said analysis of the blur of the edges;
a vital signs detector configured to detect vital signs of a subject within the scene based on image information from the detected skin areas within the acquired image; and
a display device configured to display the detected vital signs.

Abstract
A device and a corresponding method for skin detection to enable a reliable, accurate and fast detection are disclosed. The proposed device comprises an illumination unit configured to project a predetermined illumination pattern onto a scene, an imaging unit configured to acquire an image of the scene, and an evaluation unit configured to evaluate the acquired image by analyzing the imaged illumination pattern as reproduced in the image and to detect skin areas within the image and distinguish them from non-skin areas within the image based on said analysis.

13. A method for skin detection comprising:
-
projecting a predetermined illumination pattern comprising a grid or array of lines, crosses, or dots onto a scene, acquiring an image of the scene, evaluating the acquired image by analyzing the imaged illumination pattern as reproduced the image by analyzing blur of edges of the imaged illumination pattern as reproduced in the image; detecting skin areas within the image and distinguishing them from non-skin areas within the image based on said analysis; detecting vital signs of a subject within the scene based on image information from the detected skin areas; and displaying the detected vital signs on a display device. - View Dependent Claims (14)
