How to stitch a large number of panoramic groups of photos automatically?

Thank you. Sweep Panorama of Sony is exactly what I was asking about, but I did not know this term.

I noticed that Sony's other smaller non-SLR cameras have the Sweep Panorama mode too. My next camera, which may come soon, must have that feature.

I have just noticed another person asked about this feature for Canon more than a year ago. I thought I could not not the only person tired of using a stitch application to generate panorama picture one at a time.
