Lossless Zoom: Preserving Image Quality in Digital Zooming
Lossless Zoom: Preserving Image Quality in Digital Zooming
8 PagesThis whitepaper explains lossless zoom, a digital zoom technique that maintains image quality by using excess resolution from high-resolution sensors. Unlike traditional digital zoom, which introduces pixelation, lossless zoom preserves detail as long as the output resolution remains within the available pixel range. The paper compares lossless zoom with optical and lossy digital zoom, highlighting its advantages in panoramic and multisensor cameras. This capability enables users to zoom into critical details without sacrificing clarity, enhancing forensic value in surveillance applications.
