A toed-in integral imaging method is proposed to increase the three-dimensional(3D) viewing angle of integral imaging. The method contains a toed-in integral imaging 3D pickup process and a toed-in integral imaging 3D display process. In the toed-in 3D pickup process, the shooting angle of each micro-lens is not centrosymmetric anymore, and it is set based on the position of each micro-lens in the micro-lens array. The shooting angle of each micro-lens contains upper, lower, left and right shooting angles. In the toed-in 3D display process, the parameters for the 3D display are the same as the parameters in 3D pickup process and the pitch of the elemental image is larger than that of the micro-lens， by which the viewing angle of each micro-lens is converged together, and the 3D viewing angle is increased. In the simulating experiments, the 3D viewing angle of toed-in integral imaging is about 3.4 times of conventional one, in addition the crosstalk is eliminated as well. The experimental results verify the correctness of the theoretical analysis.
