Systems, methods, and devices for generating high-resolution multispectral light-field images are described. The systems and devices a main lens include a microlens array, a multispectral-filter array that comprises spectral filters that filter light in different wavelengths, and a sensor that is configured to detect incident light. Also, the main lens, the microlens array, the multispectral-filter array, and the light sensor are disposed such that light from a scene passes through the main lens, the microlens array, and the multispectral-filter array and strikes a sensing surface of the sensor. Additionally, the multispectral-filter array is disposed so as to encode, in the light that strikes the sensing surface, a plane of the microlens array on the sensing surface of the sensor. Furthermore, the systems, methods, and devices generate high-resolution multispectral light field-images from low-resolution sub-aperture images using an optimization framework that uses a first order gradient sparsity in intensity and a second order gradient sparsity in wavelength as regularization terms. |
