English French German Digital Image Effect Processing Description 1) Default: The original image (RGB colors) [Uses : Displays the original image from the Digital Presenter.] 2) Grayscale: The image(RGB colors) is changed to grayscale. [Uses : You can enhance readability or legibility of the image.] 3) Histogram: The program shows the histogram on the left-up side. This effect is available on Default, Grayscale, Binarization mode. [Uses : Lets you adjust the Digital Presenter's bright value or turn the lamp On/Off efficiently.] ✔ Note : A histogram illustrates how pixels in an image are distributed by graphing the number of pixels at each color intensity level. This can show you whether the image contains enough detail in the shadows (shown in the left part of the histogram), midtones (shown in the middle), and highlights (shown in the right part) to make a good correction. The histogram also gives a quick picture of the tonal range of the image, or the image key type. 4) Negative: This toggles Negative and Positive Image. [Uses : Converts negative film or slide image into positive image.] 5) Binarization: Assigns the image to 1 or 0 by threshold value. The threshold ranges 16~251 and the value is not automatically decided. The default value is 128 and you can set the value of Binrization by mouse or [ ], [ ] keys. [Uses : Applied to Image Analysis / Image Interpretion. (OCR, Pattern Recognition)] 6) Edge Detection: Identifies the areas of the image with significant transitions and emphasizes the edges. Find edges,outlines the edges of an image using the Prewitt mask. [Uses : Applied to Image Analysis / Image Interpretion in the Computer Vision.] 25 Italian Spanish
