CDigital Zoom and Interpolation
Unlike optical zoom, digital zoom uses a digital imaging process known as interpolation to magnify images (A126), resulting in slight deterioration of picture quality.
Interpolation is applied at zoom positions beyond V. When zoom is increased beyond the V position, interpolation is initiated and the zoom indicator turns yellow to indicate that interpolation is being applied. The position of Vmoves to the right as image size decreases, allowing for confirmation of the zoom positions at which shooting without interpolation is possible at the current image mode setting.
When the image size is small
•Digital zoom (A168) in the Setup menu (A159) can be limited to the range at which interpolation is not in effect, or it can be turned off.
