Enabling vflip currently causes wrong colors. It seems that (at least with the current sensor setup) REG04_VFLIP_IMG only changes the vertical readout direction. Because pixels are arranged RGRG... in odd lines and GBGB... in even lines, either a one line shift or even/odd line swap is required, too, but apparently this doesn't happen. I finally figured out that this can be done manually by setting REG04_VREF_EN. Looking at hflip, it turns out that bit REG04_HREF_EN is set there permanetly, but according to my tests has no effect on the pixel readout order. So my conclusion is that the current documentation of sensor register 0x04 is wrong (has changed after preliminary datasheet version 2.2). I'm pretty sure that automatic vertical line shift/switch can be enabled, too, but until anyone finds ot how this works, we have to stick with manual switching.
