The 1D integral imaging contains parallax images＇ capture process, parallax images＇ virtual reconstruction process, and ID elemental image array＇s generation process. A pixel mapping algorithm is deduced to implement the last two processes; a ID elemental image array is generated by the mapping of pixels on the parallax images obtained using a ID camera array. The proposed ID integral imaging can capture the ID elemental image array of a real three-dimensional （3D） scene.展开更多
