波形示波器
波形显示可提供和传统亮度波形监视器类似的数字编码波形,可用于监看视频信号的亮度电平指标。
图表底部表示黑电平,也就是画面中的暗部区域;而图表顶部则表示白电平,即亮部区域。顶部和底
部之间的部分则表示您正在查看的图像的整体对比度。不同的视频素材,其波形显示各有不同。如
果您监看的视频具有高对比度,那么波形图中可能不会显示任何中灰色数值。
为获得最佳视频级别且不出现裁切,请务必确保波形中的黑色部分不低于
0%
,白色部分不高于
100%
。
如果这些指标超限,视频画面将出现裁切,而呈现出来的画面就会丢失暗部和亮部细节。
波形监视器可通过图形来呈现画面,显示出视频画面中所对应的相同横向位置的亮度值。比如,如
果拍摄户外场景,画面左侧的天空部分出现过曝,那么您将相应看见波形图左侧的数值超过
100%
。

分量示波器
RGB
分量示波器可分别显示红、绿、蓝三个色彩通道的亮度波形。这一分量图可对三个色彩通道给
出清晰对比,方便您监看每个通道的指标级别,并且通过比对每个通道的高光、中间调和暗部来检
查出色偏现象。举例说明,如果蓝色通道的暗部位置较高,那么画面暗部将出现蓝色。
这样一来,您就能查看到每个色彩范围的不同之处,比较每个色彩通道,从而获得非常具体的画面
整体色彩掌控。因为分量示波器能显示每个色彩通道的波形,因此您可以立即发现白平衡问题和色
偏 现 象 ,而 且 还 能 检 查 某 个 具 体 色 彩 通 道 是 否 出 现 裁 切 ,这 些 都 是 使 用 非 分 量 示
波器所不具备的优势。
这三个分开的
RGB
波形使用的是和波形示波器相同的显示准则,其顶部、中间和底部位置分别沿横
轴反馈出视频画面的高光、中间调、暗部。
