1080P和1080I都是分辨率为1920X1080的!
区别是
P是逐行扫描
I是隔行扫描
后面其他参数也是这样
你问的1080I和720P那个清楚~~这个理论上应该是1080I!
但是如果你的显示器分辨率达不到1920X1080的话!而又能满足720P要求的1280X720的话!那么就是720P的清楚!因为是逐行扫描!闪烁就少了!
清晰度高低由分辨率决定,按照高清国标要求至少要达到1280*720,当然是1920*1080的物理分辨率最佳了。
但是实际上即使是1080i的图象,平板电视也可处理成1080P,这和720P、1080i和1080P已经没有什么关系。唯一还需要720P、1080i和1080P概念的,就是高清摄像机,但是对于电视观众而言,我们只要看节目就好了,至于用什么格式摄象机拍摄的节目,并不影响观看效果。
