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 |
| 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
