Abstract
An image acquisition apparatus may include a multispectral image sensor configured to acquire an image of at least one object in an environment in which at least one illumination source exists, through eight or more channels with minimum overlap between the channels, and a processor configured to estimate illumination spectral data of the acquired image by using channel signals corresponding to the eight or more channels, and perform lens shading correction on the acquired image, based on the estimated illumination spectral data.
