As camera resolutions move higher, users want the flexibility not
to shoot at the camera’s maximum resolution for sending, (for
example), images via email or for posting images on a web site.
A typical digital camera records incrementally smaller sizes, com-
monly referred to as SQ modes, which include medium resolu-
tion, low resolution and lowest resolution. What is seldom men-
tioned is the fact that choosing these lower resolution options
with a camera other than the Olympus CAMEDIA E-10 Zoom
SLR or the Olympus C-2500L, at resolutions other than “highest”
necessitates throwing away important pixel data in the image.
The pixels are actually thrown out to accommodate a smaller
image size. Therefore images captured in these lower SQ modes
have degraded image quality for the simple reason that there are
less pixels in the smaller image.
For example, a high resolution file at 2240 x 1680 pixels must
be reduced in order to fit into a smaller resolution image space
of 640 x 480. A typical method to achieve this is to “step down”
the resolution by identifying surrounding pixels by using an al-
gorithm to identify them and throw them away, deeming them
less necessary to the final image.
TruePic™ Technology Advanced Solution
The CAMEDIA E-10 Zoom SLR with TruePic™ Technology dra-
matically improves image quality at lower resolution SQ modes
by using a far greater sampling area and an advanced algo-
rithm and does not “throw away” pixels when using SQ modes.
Rather, the algorithm learns the pattern of the image and repli-
cates it at lower resolutions.
Fringe-less Images with TruePic™
TruePic™ Technology also performs another function within
the camera’s ASICS. It eliminates blue and green artifacts by
70% to 80% (commonly called fringing) and creates smoother
edges in color transition areas of the image. The result is supe-
rior image quality.
