PhotoTechEDU Day27: Focus on Resolution

Google Tech Talks August 22, 2007 ABSTRACT Photo Technology Lecture 27: Focus on Resolution. We investigate the digital image acquisition process for factors that adversely affect the quality of acquired imagery. # The physical properties of optical systems impose a fundamental limit to the resolution of captured imagery. # Real-world optics manifest several types of aberrations, and we show how these types of aberrations affect resolution. # Image acquisition devices are imperfect, and have aliasing and other sampling artifacts that affect resolution. # We derive the 70% rule for digital imagery, and verify it experimentally. # There is a distinction between resolution and...
