The influences of the pickup process on the depth of field (DOF) of integral imaging (InIm) display have been considered while analyzing the final DOF of integral imaging display. The DOF of InIm system not only depends on the the facet braiding in the display process, but also seriously depends on the pickup process. Only the pickuped object within the certain region can capture clear elemental images, and blurry elemental images could be attained outside the region. The region that can be recorded clear elemental images is called the pickup DOF of InIm, which influences on the total DOF of the InIm display. The pickup DOF calculation formula of InIm is presented, which is compared with the DOF caused by facet braiding, and experimental results verify the proposed method in the pickup process more accurate.
