BufferedImage getRGB method performance

I need to analyze an image to see if its a black and white checkered image.

BufferedImage does provide a method where I can get the pixel information for an image.

What are the performance implications of the getRGB method()? People mention that using this method causes severe performance degradation.

I have a scanning application where a user will scan in multiple pages.Multiple pages can be part of one document.

The checkered page acts as document separator. So I will be analyzing each scanned in image to see if its a checkered image.
