i.Resolution.
Is a further attempt by
Panasonic to increase the
apparent “sharpness” in the
JPEG camera image. It has
the two options i.Zoom and
ON. In the i.Zoom mode it
can be used to gain
increased digital zoom at
what Panasonic refer to as
minimal loss of image quality.
Confusingly, Panasonic call this “Extended Optical Zoom”. They claim
this to be equivalent of an increase in optical zoom for the reason that
the “cropped image on the sensor” provides a final image quality that
shows no deterioration in print quality. The reason this occurs is for the
fact that if you reduce the image size you require, effectively less pixels.
So from a 4000 x 3000 pixel sensor if we require an output that is say
8M (3264x2448 pixels) rather than a software down-sampling they chose
to create this image from the central area of the 4000x3000 pixels.
The effect is as though you had increased optical zoom.
