    • A method is disclosed for capturing one or more images that include a lightning strike using an image capturing device. The method is performed by one or more processors of the image capturing device. The one or more processors automatically capture a plurality of images during a period of time using the lens of the device. Each of the plurality of images is processed to detect a presence of lightning within each image. Each image is processed based, at least part, on two consecutive captured images. Images that have been determined to include the presence of lightning are stored in a memory resource of the image capturing device.
    • 公开了一种用于捕获包括使用图像捕获装置的雷击的一个或多个图像的方法。 该方法由图像捕获装置的一个或多个处理器执行。 一个或多个处理器在使用该设备的镜头的一段时间期间自动地捕获多个图像。 处理多个图像中的每一个以检测每个图像内的闪电的存在。 每个图像至少部分地基于两个连续的拍摄图像进行处理。 被确定为包括闪电存在的图像被存储在图像捕获装置的存储器资源中。

    • A readout frequency of a sensor of a digital image capturing device is set based on a frequency of alternating current (AC) mains so that a readout period of the sensor of the digital image capturing device is not an integer multiple of a flicker period. The flicker period is equal to half of a period of the AC mains. A first image frame and a second image frame are captured using the sensor of the digital image capturing device. The second image frame is captured later in time than the first image frame. Whether flicker has occurred in the first and second image frames due to a periodic fluctuation of light emitted by a light source powered by the AC mains is detected by comparing a brightness of an area of the first image frame to a brightness of a corresponding area of the second image frame.
    • 基于交流(AC)电源的频率来设定数字图像捕获装置的传感器的读出频率,使得数字图像捕获装置的传感器的读出周期不是闪烁周期的整数倍。 闪烁周期等于交流电源周期的一半。 使用数字图像捕获装置的传感器捕获第一图像帧和第二图像帧。 第二个图像帧比第一个图像帧在时间上被捕获。 通过将第一图像帧的区域的亮度与第一图像帧的对应区域的亮度进行比较来检测由于由AC电源供电的光源发射的光的周期性波动,在第一和第二图像帧中是否发生闪烁 第二个图像帧。
