An important role of copiers and scanners is to
faithfully
reproduce the image quality of the original. With digital
cameras, on the other hand, it is essential to regenerate captured images
naturally
.
However, attempting to faithfully reproduce a captured image does not always result in a natural image. This is
why
image rendering
, an inherent technology of digital cameras, is so important to digital photography.
Image rendering is the inclusion of several elements including ‘exposure control appropriate to the scene
Æ
auto exposure (AE)’, ‘color reproduction based on human sense
Æ
addition of memorized colors’, ‘faithful
color reproduction independent of background colors/color reproduction that compensates for the color
temperature of the light source
Æ
auto white balance (AWB)’ and ‘tone representation that looks natural to the
eye

characteristic’. Obviously, image rendering assumes that ‘precise focus control

is performed as well.
