摘要
The existing lensless compressive camera ((LC2)-C-2) [1] suffers from low capture rates, resulting in low resolution images when acquired over a short time. In this work, we propose a new regime to mitigate these drawbacks. We replace the global-based compressive sensing used in the existing (LC2)-C-2 by the local block (patch) based compressive sensing. We use a single sensor for each block, rather than for the entire image, thus forming a multiple but spatially parallel sensor (LC2)-C-2. This new camera retains the advantages of existing (LC2)-C-2 while leading to the additional benefits of fast acquisition, real time reconstruction, and the flexibility to image size. We develop multiple geometries of this block-wise (LC2)-C-2 in this paper. We have built prototypes of the proposed block-wise (LC2)-C-2 and demonstrated excellent results of real data.
