They target two major goals in computational photography. high dynamic range (HDR) imaging and image superresolution (SR). HDR imaging refers to capturing both bright and dark details in the scenes simultaneously. A modulo camera does not get saturated during exposure, enabling HDR photography in a single shot without losing spatial resolutions. The second camera achieves image super-resolution with its non-conventional pixel design. It is shown that recording multiple images with a sensor of asymmetric sub-pixel layout increases the spatial sampling capability compared to a conventional sensor. Both proposed camera designs are the combination of novel imaging sensors and image recovering algorithms. Their potential applications include photography, robotics, and scientific research. Theoretical analyses and experiments are performed to validate our solutions.","abstract_html":"In this thesis, two computational camera designs are presented.
