Let's start this one with a question-
Do you love the camera that is with you?(I'm talking about the one you carry with yourself, the one interfaced to your cell phone.)
Most probably NO. Be it a BIGGGG NO or a SMALL NO, but it's a NO.
Possible reasons for the unsatisfied desire:
1. Clarity sucks.
It just feels too bad when the image loses the important details it needs to carry.
2. Too slow.
This is the most irritating one as people need to hold a pose or an awesome smile for too long, hurting your jaws.
3. Imperfect Auto focus.
The camera most of the times takes too long to focus on the object you desire to snap. E.g. Text on a magazine or a journal.
4. Digital Zoom:
Nobody likes digital zoom, we all want optical zooming capabilities. Digital zoom is the one in which the image loses its clarity on zooming.
Cause:
The lens used in all the cameras is made with Glass. And the problem with glass is that it's dimensions cannot be modified. So a solution already implemented in digital cameras and DSLRs is moving the lens forward or backward with a set of motors. But this isn't practically possible to implement in a cell phone due to probability issues and we don't enough battery life for playing angry birds, how can we power the motors.
Possible Solution:
A great solution Philips is working on is its FluidFocus technology. As the name suggests the technology uses fluids for lens. The lens used is made up of a liquid (similar to water, but supposedly not water) and oil and a power supply which creates a potential difference between the two liquids. To provide for great focus and zooming capabilities, the voltage is changed and as a consequence of surface tension, the curvature changes and thus changes the focus. So we can focus on a very close object or a very distant object just by changing the curvature using the potential difference.
Advantages:
1. Theoretically Infinite zooming.
2. Extremely small in size (~2.5mm).
3. Can be used in cell phones.
4. Cheap.
