{
With this method the rows of the sensor are read out twice with different gains (Gain A /
Gain B). The gain factor between Gain A and Gain B is set using the HDRGainRatioSelec-
tor feature.
By reading out the rows twice, an image with twice the height is generated. The image
is calculated to the previous height, taking into account the different gains and can be
adjusted with further settings (e.g. tone mapping).
Notice
Because each row is read out twice (Gain A / Gain B), the frame rate is halved.

With this method every row of the sensor are read out with different exposure times (Ex-
posure Time Row 1: HDRExposureTimeBrightArea / Exposure Time Row 2: HDRExpo-
sureTimeDarkArea.
The resulting image can be adjusted with further settings (e.g. tone mapping).
Notice
With this method, the number of rows read out is the same as for a non-HDR image.
The framerate is unchanged.
