Is there a camera available with a digital backdrop feature, such as one that you wou

[mickfolley]

I am interested in creating a white background behind my subject. I know this can be done through photoshop, but is too time consuming. I took hundreds of photos this month for a car dealership project with web design company , and would like to put the vehicles in with a white background, rather than the car lot.
Is there a camera available (preferably point and shoot) that has such a feature available?
Thanks for any info anyone might have! :-)
