color CMOS QSXGA (5 megapixel) image sensor with OmniBSI™ technology
OV5647
proprietary to OmniVision Technologies PRELIMINARY SPECIFICATION version 1.0
4.4 50/60Hz detection
When the integration time is not an integer multiple of the period of light intensity, the image will flicker. The function of
the detector is to detect whether the sensor is under a 50 Hz or 60 Hz light source so that the basic step of integration
time can be determined. Contact your local OmniVision FAE for auto detection settings.
