English21Resolution boxResolution is used to decide how delicate thescanner captures the original image.When the original is scanned and turned into adigital image, the scanner captures and records theimage in terms of pixels. As more pixels are usedto record an image, more details in the image canbe represented.Resolution is usually measured in dpi (dot per inch). If you plan toscan an image using higher resolution, the scanner will record theimage with more pixels thus improving the quality of the scannedimage.One drawback of scanning at higher resolutions, however, is theamount of memory required to store these images. In addition, asresolution increases above a certain value, the file size of the scannedimage will become larger without improving the image quality. It istherefore recommended that you select a scan resolution appropriateto the purpose of your scan job.You can select resolution (ranging from 200dpi to 2700dpi) from theResolution box or select Custom… to customize resolution. Thefollowing dialog box will appear:You can adjust the resolution of the X(horizontal) and Y (vertical) axisindependently by dragging the scrollbars in this dialog box. This mayhowever cause the resolution of theX-axis to be different from that of theY-axis. Consequently, the shape ofthe original image will be altered. Toavoid this, you can check the Synccheck box to adjust the resolutions ofthe X- and Y-axes simultaneously, which will constrain the proportionsof the original image.When you get the desired effect, click on the OK button to confirmyour settings and close the dialog box. If you are not satisfied with theadjustment, click on the Cancel button to cancel your settings andclose the dialog box. |
