Abstract
Provided are an apparatus and a method for capturing images by applying different color filters to two pixel regions with IR blocking filters removed so that optical signals in the visible band and IR signals can be received. The apparatus includes a filter unit having a plurality of filters having different wavelength bands; a sensor unit sensing optical signals passing through the filters; and a signal-extraction unit extracting detailed optical signals in respective wavelength bands by using the difference between the sensed optical signals.
