Abstract

The paper describes an image generation pipeline able to realize a "viewfinder". The viewfinder of a typical handset device allows user to track in real time the scene under detection. The pipeline is composed by a set of blocks implementing demosaicing and image enhancement algorithms with new and efficient techniques able to reduce considerably the computational overhead. Experiments show how modest computational resources can be coupled with acceptable perceived image quality for this particular target.
