4 image sensor core digital functions
4.1 mirror and flip
The OV5647 provides mirror and flip read-out modes, which respectively reverse the sensor data read-out order
horizontally and vertically (see
figure 4-1). In flip mode, the OV5647 does not need additional settings because the ISP
block will auto-detect whether the pixel is in the red line or blue line and make the necessary adjustments.
