Smaller Pixels for Higher Resolution
Reducing pixel size can increase a digital camera's performance. However, there are tradeoffs that need to be considered when going that route. In the search for ever-higher pixel counts for the digital still camera, it is clear that, if chip size remains constant, then “more pixels” means “smaller pixels.” The incentive in keeping the silicon area of the sensor as small as possible is lower chip cost. A larger chip also requires a larger and more costly lens, extra space on a printed...
