An approach to the software defined camera creation (review)

The paper proposes an approach to software defined digital camera creation which is able to change it's features on the fly without moving parts and mechanical changes in optical system. The proposed approach is based on conception of liquid crystal diaphragm with software defined form, the lens with distortion and programmable zones of reading from photo sensor. Besides the task of reading and processing of data obtained from photo sensor the digital signal processor of software defined camera needs to control all of the camera components to be able to reach needed optical and information performance. The possible structural scheme of a such camera is presented which can become the basis for development of the next generation of digital cameras.
