HPL-2006-129 Analysis of Systems for Superimposing Projected Images - Said, Amir Keyword(s): display; signal synthesis; optical signal processing; image generation; deconvolution; wobulation Abstract: The addressable resolution of digital projectors can be increased by using a technique called "wobulation," which consists of using mechanical actuators to rapidly shift projected images (subframes) by fractions of pixel lengths, in one or two directions. This way the visual quality o...
