Why images captured by image processing sample has vertical stripes?

When using the ImageProcessing example to get imags, you will see vertical stripes.

In this sample, there is some extra processing:
SimpleImagingLib::ImagingBuffer *lImagingBuffer = gImagingBuffers + lBuffer->GetID();
// Retrieve our image based on buffer ID - which has been set to the index of the array
lContrastFilter.Apply(lImagingBuffer);

This is to show "how to process data", and it makes your image filled with stripes.

You could simply delete them, then you will see correct image.

If you want to process image, please use your own code at the position of lContrastFilter.Apply().
