Software ISP Sample

The software Image Signal Processor (ISP) sample demonstrates how to use the GPU image processing available in NVIDIA® DriveWorks to convert from a RAW camera frame to a common DriveWorks image type, e.g., RCB. It uses the Software ISP API.

Software ISP Sample

The sample reads frames from a RAW camera recording, processes the frames to convert them to RCB format, and displays the result on screen. 

./sample_isp

The RAW pipeline provides options to select the demosaicing method. The default is to use the DW_DEMOSAIC_DOWNSAMPLE method. This method is fast but reduces the resolution of the frame. To produce full resolution output, change the demosaicing method to DW_DEMOSAIC_INTERPOLATION via: 

./sample_isp --interpolationDemosaic=1

It is possible to demosaic only a certain region of interest via the --enableCrop=0 and --cropLeft, --cropTop, --cropWidth, --cropHeight options: 

./sample_isp --enableCrop=1

For the full list of options, run the sample with the --help argument.
