12. ST VGXY61 camera sensor driver¶
The ST VGXY61 driver implements the following controls:
12.1. V4L2_CID_HDR_SENSOR_MODE¶
Change the sensor HDR mode. A HDR picture is obtained by merging two captures of the same scene using two different exposure periods.
| HDR linearize | The merger outputs a long exposure capture as long as it is not saturated. | 
| HDR subtraction | This involves subtracting the short exposure frame from the long exposure frame. | 
| No HDR | This mode is used for standard dynamic range (SDR) exposures. |
