• Resumen

  • The article provides information about digital photography. Digital cameras come with lots of bells and whistles. But what matters more is picture quality, and it has improved significantly in the newest pixel takers. Instead of striking unexposed film, light entering a typical digital camera is focused onto a charge-coupled device. A microprocessor reads the charge in each pixel as a digital signal and constructs an image of the scene. A so-called four-megapixel camera has a charge-coupled device with four million pixels. The higher this resolution, the sharper the photograph. But affordable lens systems cannot resolve light into more than six or eight megapixels.
