Pixel Depth | Select the form of the image data. Each option | |
| below identifies a data format that specifies the | |
| number of bits used to represent the tone of a pixel. | |
| The more bits per pixel, the more tones and colors | |
| you can capture in the scanned image. The | |
| highest number of bits possible is 24 bit color (or | |
| True Color), which can represent over 16 million | |
| colors. |
|
| Note, however, that the output devices you use | |
| should be capable of producing the same tones. | |
| Also, the larger the bits per pixel value chosen, the | |
| larger the size of the Image data. | |
| Possible values are: |
|
| Black and White | 8 Colors |
| 16 Gray Scale | 16 Colors |
| 255 Gray Scale | 64 Colors |
|
| 256 Colors |
|
| True Color |
|
| |
Halftone | Define the halftone processing applied to the | |
| scanned image. You will generally want to select | |
| None and let your image editing software or the | |
| output device perform the halftoning. | |
| The selections you see vary depending on the | |
| scanner you are using. Possible values are: | |
| None | Bayer dither |
| Hard Tone | Spiral dither |
| Soft Tone | Net dither 4 |
| Net Screen | Net dither 8 |
