Three-dimensional image sensors and methods of manufacturing the same

Image sensors include three-dimensional (3D) color image sensors having an array of sensor pixels therein. A 3-D color image sensor may include a 3-D image sensor pixel having a plurality of color sensors and a depth sensor therein. The plurality of color sensors may include red, green and blue sensors extending adjacent the depth sensor. A rejection filter is also provided. This rejection filter, which extends opposite a light receiving surface of the 3-D image sensor pixel, is configured to be selectively transparent to visible and near-infrared light relative to far-infrared light. The depth sensor may also include an infrared filter that is selectively transparent to near-infrared light having wavelengths greater than about 700 nm relative to visible light.
