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