Introduction

This application demonstrates the use of VISS node and TI's 2A (AE & AWB) algorithm. It captures RAW images from the image sensor, processes it in VPAC and displays using Display Sub-System. It also processes H3A data for AE and AWB algorithms.

Supported plaforms

Platform	Linux x86_64	Linux+RTOS mode	SoC

Data flow

Steps to run the application on J721e EVM

1. Build the application and related libraries as mentioned in Build Instructions
2. Connect camera board on cam0 input port of the Fusion1 Platform
3. Use the is_interactive flag to run the demo in an interactive mode which allows the user to select sensor, processing options and print performance characteristics on the UART console.
4. Run the app as shown below

   ./vx_app_single_cam.out

5. The output is displayed through DSS on HDMI or eDP display - Display interface selection through compile time srtting in the file apps/basic_demos/app_tirtos/common/app_cfg_mcu2_1.h
