  DESIGN FEATURES Photoflash Capacitor Chargers
  Keep Up with Shrinking Cameras
  by Mike Negrete Introduction
  Camera-phones have come a long way
  since the п¬Ѓrst generation of integrated
  cameras offered low-resolution CMOS
  images through the eye of a plastic
  lens. Now PDAs and high-end cell
  phones include high quality cameras
  with 2 megapixel resolutions and glass
  optics. Since these devices are carried
  by most users at all times, size is of the
  utmost importance. LED flashes were
  introduced in early model cell phone
  cameras, but they cannot produce
  enough light and lack the spectral
  quality required for higher-end cameras. Although xenon flashes are an
  optimal source of light for photography, they required substantially more
  board space than LED flashes until
