It is reported that apple has purchased camera sensor maker LinX. LinX makes multi-element camera assemblies for computers, smart phones and tablets. The LinX sensors are capable of refocusing the image after it has been captured, similar to the Lytro light field camera that I've talked about before. There is no word from Apple as to when they will start using these sensors, or even if they will use them. If they did start using these sensors the picture quality would certainly begin to rival that of a DSLR. Right now we can only wait and see what Apple has planned for these little wonders. You can read more about it here and here.
