In early 2004 the average point-and-shoot camera we tested had a little more than 4Mp (megapixels). Now the average is nearly 6.5Mp. And that number may climb: companies such as Adobe are dreaming up concepts that will require much greater resolution - and point-and-shoot cameras could benefit from this megapixel mania.

Adobe's Advanced Technology Labs showed us a prototype lens that incorporates 20 smaller lens elements (each with 10Mp resolution, for a total of 200Mp) in a honeycomb pattern. Each element captures the same image but with a different depth of field and focus; you can then select the image with the depth and focus you want, or use Adobe's skunk-works software to combine portions of each element.
