Overcranking, for example, is only available at ∼1 million pixel (1280 × 720) resolution, and the maximum frame rate of today's 1920 × 1080 progressive cameras is 30 Hz. To truly offer a compelling alternative to motion imaging film, electronic HD cameras must provide a higher progressive frame rate along with additional bit depth to maximize production quality and creativity. In this paper, the technical background for the shift in technology from CCD imaging to CMOS imaging system-on-chip is discussed. Specifically, the sensor architectures are compared, and why CCD noise consistently increases with video frequency at about 3 dB/octave is explained. We conclude by briefly reporting the development status for a complimentary metal oxide semiconductor (CMOS) 1920 × 1080 image sensor for next-generation, affordable and compact HD cameras to support progressive frame rates at 60 Hz and beyond.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J16267.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-journal-article-nlm@v1" }, "authors": [ { "bio": "Les Kozlowski is chief technology officer at AltaSens, Inc., a startup focused on producing highly-integrated, high-performance CMOS imaging systems-on-chip for next generation video products including HDTV.
