Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. An image acquisition method comprising:
obtaining a first image by using a first hyperspectral image sensor; and
processing the first image obtained by the first hyperspectral image sensor,
wherein the processing of the obtained first image comprises:
extracting a first spectrum of each pixel of the first image obtained by the first hyperspectral image sensor;
correcting the first spectrum by normalizing the first spectrum of each pixel;
distinguishing an object from a background within the first image by recognizing a pattern of the first spectrum of each pixel; and
correcting a color of the object and a color of the background based on a spatial distribution of illuminations;
obtaining a second image based on a second hyperspectral image sensor,
wherein an average value of a second spectrum of each pixel of the second image is applied as an illumination average value to correct the first spectrum by normalizing the first spectrum of each pixel.
