Image Quality—HyPict™ Image Enhancement Technology
Many digital cameras use an interpolation method to produce images with higher resolution than the camera's
CCD can capture. EPSON HyPict image enhancement technology uses an exclusive interpolation method.
EPSON HyPict image enhancement technology produces more
accurate results because it applies image enhancement before
JPEG compression.
The EPSON HyPict image enhancement technology uses
an in-camera processing system to interpolate an image
using full image data.
After the image is interpolated, the camera then converts
it to JPEG file format.
Other image enhancement technologies convert to JPEG
file format before enhancement. Since JPEG conversion
removes image data, these technologies do not use full
image data for the interpolation, resulting in less accurate
images.
Image quality—Resolution modes
EPSON digital cameras allows you to select different image quality settings. (Not all of these settings are available
for each model.)
The following chart explains the differences between the image quality settings:

Additionally, some EPSON digital cameras include a TIFF Uncompressed image quality setting, which does not
remove any image data through compression.
