Abstract
Progress in optics and information technologies promotes an emerging research field for imaging called
computational imaging. Owing to combinatorial diversity of optical encoding and computational
decoding, various kinds of high-functional and high-performance imaging are developed as a framework
of computational imaging. Fundamental reasons of the active development of the technology are not
only tremendous increase of computational power but also availability of efficient optical devices, such
as a microlens array for light field acquisition/display and spatial light modulators for light distribution
control. This special issue intends to provide an overview of this research field including light field
imaging/display, digital holography, novel phase imaging, and single pixel imaging. Marriage of optics
as a physical system and a current information technology is considered as quite modernized and
promising. This special issue is expected to show a signpost for the readers requiring unconventional
imaging methodologies.
