This survey covers ongoing research that may break through existing bar-riers by combining ideas across computational photography, compressive sensing, micro/nano optics, sensor fabrication, and embedded computer vision. So, computational photography represents a threat because its value comes largely from algorithms. - Computational photography attempts to record a richer visual experience, captures information beyond just a simple set of pixels and makes the recorded scene representation far more machine readable. Computational photography is the art, science, and engineering of creating a great (still or moving) image. Finally, we demonstrate the effective- ness of the proposed method on two typical applications, including LFOV imaging and EDOF imaging. Computational Photography I he digital camera has brought jl a revolutionary shift in the nature of photography, sweeping aside more than 150 years of technol ogy based on the weird and wonderful photochemistry of silver halide crystals.
