Digital Zoom and Image Quality
When the camera is zoomed in to the maximum optical zoom magnification,
rotating and holding the zoom control at
g (i) triggers digital zoom. With digital
zoom, you can magnify a subject up to 4× the maximum magnification of optical
zoom (18×) for a total of up to 72× magnification.
Focus will be on the center of the screen (without active focus area display) when
digital zoom is in effect.
Unlike optical zoom, digital zoom uses a digital imaging process known as
interpolation to magnify images, resulting in slight deterioration of picture quality.
The V icon appears under the zoom indicator at the top of the monitor to mark
the maximum zoom ratio possible before deterioration from digital zoom occurs.
When the zoom ratio exceeds V towards the telephoto side, the zoom indicator
will turn yellow and picture quality will begin to deteriorate.
C
Maximum zoom ratio without interpolation
The position of V under the zoom indicator moves closer to the telephoto side as the image size
(
A 89) gets smaller. Deterioration from digital zoom will not occur until the zoom ratio reaches the
following levels for each mode.
When the zoom ratio reaches the following levels, zoom operations pause temporarily. If you
continue to hold the zoom control at
g (i) and increase the zoom after this point, the images will
start to get grainier.
Digital zoom can be limited to the range at which interpolation is not in effect, or it can be turned off
