5.4 Multi Camera VPAC Application Demo

This application demonstrates the use of the VISS node and TI's 2A (AE and AWB) algorithm. The dataflow is as shown below:

  1. Configure image sensors using the sensor driver firmware APIs.
  2. Acquire RAW images from camera sensors.
  3. Process the images on VISS.
  4. Run Auto Exposure (AE) and AutoWhiteBalance (AWB) algorithms, using H3A output from VISS.
  5. Run LDC on the output of VISS.
  6. Scale LDC output using MSC and arrange in a mosaic.
  7. Display the mosaic using display subsystem.
