Abstract
Methods and apparatus for capturing and rendering high-quality photographs using relatively small, thin plenoptic cameras. Plenoptic camera technology, in particular focused plenoptic camera technology including but not limited to super-resolution techniques, and other technologies such as solid immersion lens (SIL) technology may be leveraged to provide thin form factor, megapixel resolution cameras suitable for use in mobile devices and other applications. In addition, at least some embodiments of these cameras may also capture radiance, allowing the imaging capabilities provided by plenoptic camera technology to be realized through appropriate rendering techniques. Hemispherical SIL technology, along with multiple main lenses and a mask on the photosensor, may be employed in some thin plenoptic cameras. Other thin cameras may include a layer between hemispherical SILs and the photosensor that effectively implements superhemispherical SIL technology in the camera.
