Zusammenfassung:	The present invention relates to a multi-spectrum-based skin pigment analysis method and an apparatus thereof which can be carried at a low price by using a light source and a camera for multi-spectrum analysis. The method comprises: (a) a step of acquiring an image for light having a wavelength of 400nm to 1,000nm; (b) a step of acquiring a prescribed Bayer color filter array (CFA) from the image; (c) a step of analyzing a spectrum band of R, G, and B of light in the Bayer color filter array; and (d) a step of using the analyzed spectrum band of R, G, and B of light to calculate the distribution of chromophores including melanin, oxidized hemoglobin, and reduced hemoglobin. 본 발명은 다중 분광 기반 피부 색소 분석 방법 및 그 장치에 관한 것이다. 상기 방법은, (a) 400nm 내지 1000nm 파장을 갖는 광에 대한 영상을 획득하는 단계; (b) 상기 영상에서 소정의 베이어 색상 필터 배열(Bayer color filer array: CFA)을 획득하는 단계; 및 (c) 상기 베이어 색상 필터 배열에서 광의 R, G, B 각각의 스펙트럼 대역을 해석하는 단계; 및 (d) 상기 해석된 광의 R, G, B 각각의 스펙트럼 대역을 이용하여, 멜라닌, 산화헤모글로빈, 및 환원헤모글로빈을 포함하는 색소포의 각 분포를 계산하는 단계를 포함할 수 있다.
