# 2D camera head configuration

| Article | Image resolution 2D [pix] | Angle of aperture [°] | Framerate [Hz] |
| --------| ------------------------- | --------------------- | -------------- |
| O3R222 | 1280x800 | 128x80 | 20 |
| O3R225 | 1280x800 | 128x80 | 20 |

## Mode
|Variable name|Short description|
|--|--|
|`mode` (for the 2D imager) |This parameter designates the acquisition mode: auto or manual exposure |standard_autoexposure2D, standard_manualexposure2D |

## Exposure time
|Variable name|Short description|
|--|--|
|`exposureTime`| Exposure time used for the acquisition of the RGB image, in ms.|

## Gain
|Variable name|Short description|
|--|--|
|`gain`| Image gain (affects sensibility to light).|

The gain is particularly useful in low light situations, used in combination with the exposure time: increasing the exposure time as well as the gain will result in a brighter image.
