Zusammenfassung:Disclosed are digital imaging devices that embody a method for eliminating modulated light effects in rolling shutter CMOS sensor images. The digital imaging device comprises an image sensor utilizing an electronic rolling shutter, a processor and firmware for implementing the methods. Embodiments of the method comprise detecting the presence of light modulation and the frequency of the light modulation, and synchronizing the exposure times to the modulation cycle time.
