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

Claim 0:
1. An image acquisition apparatus comprising:
a first hyperspectral image sensor configured to obtain a first image;
a second hyperspectral image sensor configured to obtain a second image; and
a processor configured to process the first image obtained by the first hyperspectral image sensor,
wherein the processor is further configured to:
extract a first spectrum of each pixel of the first image obtained by the first hyperspectral image sensor;
correct the first spectrum by normalizing the first spectrum of each pixel;
distinguish an object from a background within the first image by recognizing a pattern of the first spectrum of each pixel;
correct a color of the object and a color of the background by using a spatial distribution of illuminations;
obtain an average value of a second spectrum of each pixel of the second image obtained by the second hyperspectral image sensor; and
apply the average value of the second spectrum of each pixel of the second image obtained by the second hyperspectral image sensor to an illumination spectrum used to correct the first spectrum by normalizing the first spectrum of each pixel.
