  • Method for light flicker analysis and device thereof
    Patent number: 9865044
    Abstract: This invention provides devices and methods of determining flicker-related parameters of a light emitting source. In one embodiment, the method has the following steps: a) acquiring one or more photo images or video images of a light emitting source with an image capturing device that has a rolling shutter; b) generating, with a processor, from the photo images or video images a flicker frame having one or more flicker dark lines, wherein each flicker dark lines has an output column value of 1; and c) generating, with a processor, one or more flicker-related parameters based on the flicker frame, thereby determining the flicker-related parameters of the light emitting source.
