單位是“電視行(TVLine)”也稱線。意思是從水平方向上看,相當於將每行掃描線豎立起來,然後乘上4/3(寬高比),構成水平方向的匯流排,稱水平分解力。 因其檔案生成的體積小而廣泛套用於監控攝像領域。

From experience | ||
A/D converter and TVL | ||
the highest-resolution for 8 BIT is 480TVL, | ||
the highest resolution for 10BIT is 520TVL, | ||
the highest resolution for 12BIT is 560TVL, | ||
if the nominal is odd, for example 13BIT, 15BIT, etc., it would be a lie, the biggest market for the use of 12BIT | ||
CCD and TVL | ||
When use SONY 409/408/639/638 the highest should be 560TVL | ||
DSP and TVL | ||
No obvious relationship between them, when using 405/404/633/632 the highest should be 400TVL, when the using 409/408/639/638/213/212 the highest should be 560TVL |
