15.1 Image Processing Algorithm Variants:
There are 6 different processing variants which can be changed by pressing
‘Select’ key from the device keypad. The user can navigate through the
processing variants using key combinations. Refer
Different variants work better on different types of input images. For example, for
images containing line drawing, “1 Bit Monochrome” is preferable, while for color
images, “8 Bit Gray” generate better results. Therefore, the device allows you to
explore the effects of different algorithms on the input image.
The supported image variants are:
1. 1 Bit Monochrome
2. 2 Bit Grayscale
3. 8 Bit Grayscale
4. 8 Bit Sharpen level 1
5. 8 Bit Sharpen level 2
6. 8 Bit Sharpen level 3
7. 8 Bit Sharpen level 4
This processing includes different levels of gray scaling and sharpening of the
image after resizing it to the device’s native pin grid size (40 x 60).
