The factory default setting of an M25M with an L12 lens is a
high-resolution 180° panorama image
, in which parts of
the protective cover are still visible in the upper right and left
corners of the image.
Optimizing the M25M Panorama Image
In order to hide the protective cover in the panorama image, all that is often required is
the “panorama correction” function, which has already been integrated into the camera
software (controlling the camera via a web browser). Tilted vertical lines (if the camera is
mounted at an angle) may be optically straightened to the image edges using this func-
tion (see
Section 3.5). A welcome side effect of this is that the protective cover disappears
from the image.
If this measure does not work in some
special cases (camera tilt of approxi-
mately 0°), the protective cover can be
removed from the image by zooming
and, if necessary, by using the purely
software-based downward panning
function. The displayed image section
or the panorama, as the case may be,
is reduced slightly but the image details
are enlarged as a result of zooming.
