In this paper, we proposed a imitated light field image architecture based on Haar discrete wavelet transform for light field instrument. We can get different characteristic from subband images by using discrete wavelet transform (DWT) decomposition. Each subband contains different energy and edge type. The image is composed of many subbands by using high-order discrete wavelet transform and makes more combination with these subbands. Energy of each subband can be controlled by weight assignment. The blurry image is reconstructed by using inverse discrete wavelet transform (IDWT) with details. We can find a set of coefficients to control image from blur to clear in our simulation. We implement the discrete wavelet transform by adopting cell-based design flow to perform the architecture. The experimental results show the proposed architecture performs imitated light field image architecture based on Harr discrete wavelet transform.
