imageview

I have a bitmap and I want to scale it up to fill an ImageView and overlay the unscaled version of the bitmap on top.

Which would be cheaper (in terms of memory and processor usage)?

Using two ImageViews, one for each version of the bitmap
Using a canvas and drawing on the singular bitmap, using one ImageView

I saw this question about ImageView vs Canvas, but it doesn't address memory/processor concerns. My intuition says two ImageViews may use more RAM, while using a canvas would use more processing power while the drawing occurs.
