关于早期数字分辨率和现代电视UHDTV高清分辨率的说明

 

Resolution in various media

This is a list of traditional, analog horizontal resolutions for various media. The list only includes popular formats, not rare formats, and all values are approximate (rounded to the nearest 10), since the actual quality can vary machine-to-machine or tape-to-tape. For ease-of-comparison, all values are for the NTSC system. (For PAL systems, replace 480 with 576.)

• Analog and early digital
  • 352×240 : Video CD
  • 320×480 : Betamax, VHS, Video8
  • 360×480 : Super Betamax, Umatic
  • 400×480 : Betacam
  • 440×480 : Betacam SP, Umatic SP, NTSC (Over-The-Air TV)
  • 530×480 : Super VHS, Hi8
  • 570×480 : LaserDisc
  • 670×480 : Enhanced Definition Betamax
  • 700×480 : Analog broadcast limit (NTSC)
  • 768×576 : Analog broadcast limit (PAL, SECAM)

• Digital
  • 720×480  : D-VHS, DVD, miniDV, Digital8, Digital Betacam
  • 720×480  : Widescreen DVD (anamorphic)
  • 1280×720  : D-VHS, HD DVD, Blu-ray, HDV (miniDV)
  • 1440×1080  : HDV (miniDV)
  • 1920×1080  : HDV (miniDV), AVCHD, HD DVD, Blu-ray, HDCAM SR  (FHD电视)
  • 1998x1080  : 2K Flat (1.85:1)    
  • 2048×1080  : 2K Digital Cinema
  • 4096×2160  : 4K Digital Cinema  （4K数字电视，当前2013开始流行但尚未普及的数字电视）
  • 7680×4320  : UHDTV    （超高清电视）
  • 15360x8640 : 16K Digital Cinema
  • Sequences from newer films are scanned at 2,000, 4,000, or even 8,000 columns, called 2K, 4K, and 8K, for quality visual-effects editing on computers.
  • IMAX, including IMAX HD and OMNIMAX: approximately 10,000×7000 (7000 lines) resolution. It is about 70 Mpix, which is currently highest resolution single sensor digital cinema camera (as of January 2012).^{[citation needed]}

• Film
  • 35 mm film is scanned for release on DVD at 1080 or 2000 lines as of 2005.
  • The actual resolution of 35 mm camera original negatives is the subject of much debate. Measured resolutions of negative film have ranged from 25-200 lp/mm, which equates to a range of 325 lines for 2-perf, to (theoretically) over 2300 lines for 4-perf shot on T-Max 100.^[3][4][5] Archivists generally agree that 4k scanning of 35mm is more than adequate for archival purposes.^[6]
