Abstract
Example embodiments are directed to a stack-type image sensor including resistance change elements. The stack-type image sensor includes at least two light-sensing layers that detect different color light stacked on different layers. The stack-type image sensor may not require a size of a unit pixel that detects a light color to be less than 1 μm in order to generate a high resolution color image. As such, resolution saturation may be avoided.
