我列出的链接你真的认真看过并理解了吗?
Progressive Scan译为逐行扫描,Interlaced Scan译为隔行扫描 ...
你看了我写的那段话吗?那段也是这段WIKI里面的?看了吗?
我说的这个情况,是发生在480I的机器上的,理解了吗?你还在那里说,480P的机器是怎么填的,有用吗?
Older video game consoles and home computers often generated a technically-compliant NTSC or PAL signal, but only sent one field type rather than alternating between the two. This created a 240- or 288-line progressive signal, which in theory can be decoded on any receiver that can decode normal, interlaced signals.[1][2][3] Since the shadow mask and beam width of standard cathode ray tube televisions were designed for interlaced signals, these systems produced a distinctive fixed pattern of alternating bright and dark scan lines; many emulators for older systems offer to recreate this effect. The horizontal resolution ranged from 160 pixels to 720 pixels, depending on the video chip's capabilities (and the skill of the programmer).
but only sent one field type rather than alternating between the two.
较老的视频游戏控制台和家用电脑通常产生符合技术的NTSC或PAL信号,但仅发送一种场类型而不是在两者之间交替。
还倒打一耙说我翻译错误?
这句话你不看的吗?还是你看不懂?
field=场
rather than alternating between the two.
你见过一个画面的制式需要交替的吗?
这里当然是指的两场扫描的交替
看话你看半句的吗?还是你存心往你想要的意思翻译?
也就是,应该是
NON-Interlaced Scan隔行扫描
图像将被以奇,偶线分别扫描的方式成像,
[奇线扫描]
[1] 11111111...
[2] ------无信号
[3] 22222222...
[4] ------无信号
[5] 33333333...
[6] ------无信号
[7] 44444444...
[8] ------无信号
扫两遍。没有偶数场什么事儿。 |
