Platform and Sensor Device Drivers#

The driver divides into two main parts that are configured in separate ways – the image modes and the general features of the image sensor.

Image Modes#

These are major attributes that impact the image data stream formatting. They require a static pre-configuration within the device tree (DT):

  • Image / streaming resolution

  • Pixel format / bit depth

  • Data rate / lane configuration

Each driver provides access to 3 – 5 pre-built configurations, reflecting the main operation modes of the imager. Besides the full resolution, which is always available, they allow receiving image streams in common video resolutions like VGA, Full HD, and UHD as supported or as make sense by the imagers, and utilize sensor features like ROI and binning.

These configurations act as examples for implementation and are available as source code. Due to the size limitation of the device tree, it is not possible to integrate an extensive set of options.

General Features#

These are attributes of the image sensor that do not manipulate the data stream formatting. The drivers provided with the Software Pack integrate the sensor features as shown in the table below.
