Abstract: Light field is a representation of full four-dimensional radiance of all rays with spatial and angular information in free space,and capture of light field data enables many new development potentials for computational imaging.The light field camera can obtain 4D light field information,which can capture two more variance than traditional camera.Lytro Illum camera has more advantages than Lytro1.0 in aspect of image quality in the market.This paper used Lytro Illum to capture 4D light field information,extracting the valid light field data from the data file in the light field camera.And 8bi/pixel light field image data can be got by decoding and inverting.Then through a series of process to the light field image data based on microlenses model,4D light field data array and many sub aperture pictures can be got,laying a good foundation of the light field data development and application.

Key words: Computational imaging,Sub aperture picture array,4D light field information,microlenses model,Light field imaging technique
