| 摘 要： | 由于交流电的能量按照正弦波的形式周期性变化，当外界光源为灯光时，在曝光时间不满足交流电能量周期的整数倍的情况下，会使图像亮度随着行数的变化产生周期性变化，动态的图像看起来有条带（banding）在表面闪烁，即产生flicker．本文详细分析了fllicker产生的原因，并提出了一种自动检测flicker的方法，能够简单而有效检测到flicker的存在并进行消除．

| Abstract: | Because of the energy of alternating current is alternated periodically as the format of sine wave, when the lamp- house is generated from lamplight, at the case of exposure time is not the integer multiple, the luminance of image will alternated periodically by the line number, dynamic image will generate banding. This paper analyzes the reason of bringing flicker in detail, and brings forward a method of auto flicker detection which can detect flicker automatically and remove it. |
