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.

EPSON HyPict image enhancement technology performs all of these steps in the camera:

1.Captures image

2.Enhances and interpolates image

3.Applies JPEG compression

EPSON digital cameras allows you to select different image quality settings. (Not all of these settings are available for each model.)
