Single Frame Spots of Various Shape – also known as “Digital Dust” or “White Flecks”
Natural and/or artificial radiation may cause a “false exposure” on the image sensor. The shape of
these spots may vary from dots to lines or other, sometimes irregular shapes. These spots occur in
random locations of the image, last only for a single frame and are more visible in dark images. This is
a principle issue of all image sensors and not a malfunction.
单帧画面出现斑点，可能是多种形状 —— 也被称为“数字尘埃”或“白斑”
自然和/或人工的辐射可能会引起影像传感器的非正常曝光。这些斑点的形状可能是点状、线状或其他不
规则形状。
这些点可能会随机出现在画面的任何地方，仅持续一帧，并在画面暗部更易显现。这是影像传感器的工
作原理导致的，并非故障。
Flicker
Some light sources (i.e. discharge tubes or LEDs) may cause an interference with sensor exposure.
This may result in image flickering or “bands” of different brightness moving up or down the image.
Please note that at higher frame rates (100 fps in 50Hz countries, 120 fps in 60Hz countries) even
tungsten light may flicker. A short recording and playback will show this flicker.
For information on how to reduce flicker when filming a monitor please see Setting a Shutter Value.
频闪
有些光源（例如灯管或 LED 灯）可能会引起对影像传感器曝光的干扰。这会导致画面频闪，或者在画面
里不同亮度、上下运动的条纹。
请注意在某些高帧率下（在
50Hz 国家拍摄 100 fps，在 60Hz 国家拍摄 120 fps），甚至钨丝灯也会发生频
闪。拍摄并回放一个短视频可以检查这种频闪。
Rolling Shutter
Due to the rolling shutter design principle of the sensor the following effects can be observed in certain
situations:
Skewed/slanted vertical lines: fast panning or fast-moving objects may result in vertical structures
to appear "skewed/slanted”. The intensity of the effect depends on the relative speed of panning/
object.
Partial exposure: very short light effects (i.e. a photographer’s flash or strobe light) may result in the
upper part of the image showing the light effect whereas the lower part does not or vice versa.
滚动快门
由于影像传感器的滚动快门工作原理，某些特定场合下会出现以下现象：
歪曲/倾斜的垂直线条：快速横摇或快速移动的物体会导致垂直线条呈现出“歪曲/倾斜”的状态。其
程度取决对横摇/物体运动的相对速度。
不完整曝光：非常短的灯光效果（例如照相机闪光灯或频闪灯）会导致仅有画面的上半部分被照明而
下半部分未被照明，反之亦然。
"Black Sun"
Very bright lights (i.e. the sun, or a photographer’s flash) may result in a black/magenta spot. Note:
pointing the camera directly into the sun may damage the sensor.
“黑太阳”
非常明亮的光源（例如太阳，或照相机闪光灯）可能会成为黑色/洋红色的斑点。注意：将摄影机直接对
准太阳可能会损坏影像传感器。
