Integral imaging without image distortion using micro-lens arrays with different specifications

Abstract

Abstract. We propose an integral imaging in which the micro-lens array (MLA) in the pickup process called MLA 1 and the micro-lens array in the display process called MLA 2 have different specifications. The elemental image array called EIA 1 is captured through MLA 1 in the pickup process. We deduce a pixel mapping algorithm including virtual display and virtual pickup processes to generate the elemental image array called EIA 2 which is picked up by MLA 2. The three-dimensional images reconstructed by EIA 2 and MLA 2 do not suffer any image scaling and distortions. The experimental results demonstrate the correctness of our theoretical analysis.

Depth-enhanced integral imaging system based on spatial filtering

“…As a true three-dimensional (3D) display technology, integral imaging (II) can provide autostereoscopic 3D images for the viewers simultaneously, without any auxiliary device [1][2][3]. Also, the reconstructed 3D images have full parallax, full color, and continuous viewing points [4][5][6]. II, however, also faces some problems, such as a narrow viewing angle, an insufficient resolution, and a limited depth of field (DOF) [7][8][9][10][11][12].…”

P‐80: Multiple Orthographic Image Interleaving for Generating Tilted Elemental Image Array with an Arbitrary Angle Directly

“…Integral imaging has become an important technique in threedimensional (3D) display recent years [1][2][3][4]. In general, a conventional integral imaging includes two stages: pickup and reconstruction [5].…”
