  • Page 30: Binary Reading

    3.2 Basic image functions 3.2.3 Binary reading [A.3.3.2 CONTROL command / Control register A#1/B#1= B’xxxxxx0x’] Following three parameters are available when binarizing the image. The 256 levels of the density at each pixel is processed by Contrast and binarized by fixed Threshold (Density). When the White level following is se ON, the white level of the CCD output follows the background of the document.

  • Page 31: Halftone Reading

    Image Functions Halftone reading 3.2.4 This scanner supports two types of halftone image, that is Dither and Error Diffusion. NOTICE: The density of the halftone can not be adjusted by the Threshold in Table 3.4 but the Brightness in Table 3.5. Dither This is a way of producing halftone images with white and black pixels.
  • Page 32 3.2 Basic image functions Error diffusion This is a way of producing halftone (Pseudo grayscale) images with white and black pixels. Optical density of pixels and its adjacent pixels are totaled and black pixels are repositioned in the order of density in accordance with relations between adjacent pixels. This scheme aims to minimize errors between scanned density and printed density on the average.

  • Page 33: Grayscale Reading

    Image Functions 3.2.5 Grayscale reading [A.3.3.2 CONTROL command / Control registerA#2/B#2 = B’xxxxxx1x’] Eight bit Grayscale reading is available. Following image processing functions can be specified for grayscale reading. (See Table 3.2) • X,Y resolution • Main window area • Contrast •...
  • Page 34 3.3 Optional image function IPC-3D: Dynamic Threshold is identical to the Simplified Dynamic Threshold in IPC mode. (See section 3.3.2) NOTICE 1: Threshold, Brightness, and Contrast settings are ignored in DTC mode. NOTICE 2: Gamma correction is also ignored in DTC mode. Pre-filter The pre-filter performs filtering before processing the Dynamic Threshold.
  • Page 35 Image Functions Gradation Gradation specifies the gamma curve correction before processing Dynamic Threshold. When scanning news papers or old documents which background is dark, it is desirable that the gamma curve has coarse steps in the lighter side and fine steps in the darker side. This is called High Contrast gamma curve.
  • Page 36 3.3 Optional image function Dynamic Threshold Curve For the Dynamic Threshold function, the threshold is changed with the average optical density of a small area (e.g. 5x5 pixel area). Relation between the threshold and maximum density is formed as a curve when the threshold is expressed in the Y-axis and the maximum density in the X-axis.
  • Page 37 Image Functions This function allows a customer to select a threshold curve. Several different curves are prepared, one is the OCR type and other is the image type. The characteristic of the curve is deferent between IPC-2D and IPC-3D. IPC-2D: The image type curve has steeper inclination in the middle of the curve.
  • Page 38 3.3 Optional image function Equal to White Equal to White specifies the result of binaizing when the value of a pixel equals the threshold. The default is Equal to White OFF. The effect of this parameter is slight but, if the scanned image text is bold, set to Equal to White. If the scanned Image text is too narrow or lost, set to Equal to Black (Equal to White OFF).
  • Page 39 Image Functions Noise Removal Noise Removal reduces the isolated spot noise after Dynamic Threshold. If the image is noisy. Turn on the Noise Removal and set the granularity to the size of noise to be removed. The parameter of Noise Removal is as follows. Table 3.13 Parameter of Noise Removal Control Parameter...
  • Page 40 3.3 Optional image function Smoothing Smoothing in DTC mode is done after binarizing. This function smooths a slant line or curve by eliminating jagged edges on the line. An irregularly protruding portions are removed and an Irregularly cut portions are filled In. The parameters of smoothing are as follows. The Image Smoothing do no smoothing.

If text edges are not clear or faint, turn on the Image Emphasis. Three levels of Image Emphasis, High/Mid/Low, are available. As a side effect, Image Emphasis also emphasizes the noise.

  • Page 47 Image Functions A utomatic Separation With this feature, the scanner automatically recognize the text areas and photo areas on the document. For the areas that are recognized as text areas, scanned data are processed as pure binary with no halftone algorithm (fixed threshold or automatic binarization). For areas that are recognized as photo areas, scanned data are processed with a halftone algorithm (Dither or Error Diffusion).
  • Page 48 3.3 Optional image function Mirror image / Black and White reverse A scanned Image is turned over symmetrically in the main scan direction, generating a mirrored reflection of an image. Black and White Reverse turns the black part of the Image white and white part of the Image black. This effect Is similar to the negative/positive Images from camera.

    Image Functions Zooming 3.3.4 [A.3.3.3 IMAGE CONTROL command / Image control registerA#5,A#6/B#5,B#6] Zooming is the function to enlarge or reduce the image from 400 dpi. X and Y independent variable resolutions are supported. This zooming is processed in grayscale, so smooth and non-distorted images can be obtained even when halftone is applied.

  • Page 198 A.4 Third Party Slot A.4.5 Logical Specification Please refer to Chapter 6 for logical commands/statuses those sent or received in control signal. Multi-bit image data is available from this third party slot. To validate multi-bit scanning, bit 1 in control register #2 must be set to ‘1’.
  • Page 199 Duplex reading B.2 Extended control register #2 The basic transfer rate of M3097DE is two times faster than that of M3093DE. Front-side transfer rate depends upon the output resolution. This is because the scanner reads front-side image while transferring the data. Back-side transfer rate is selectable from basic speed to fourfold speed. The transfer rate is specified by the extended control resistor #2 as follows.
