Digital Zoom and Interpolation
Unlike optical zoom, digital zoom uses a digital ima()ing process known as
interpolation to magnify images, resulting in slight deterioration of picture
quality.
Interpolation is applied at zoom positions beyond
(;1.
When zoom is increased
beyond the
[>
position, interpolation is initiated and the zoom Indicator turns
yellow to indicate that interpolation is being applied. The position of [)
moves to the top as image size decreases, allowing for confirmation of the
zoom positions at which shooting without interpolation is possible at the
current image mode setting
(OJ

Digital zoom can be disabled from the Digital zoom option
(CD

in the Small image size
setup menu
(OJ
