Figure 4-11 HP Digital Imaging Options dialog box HP drivers for Windows The following settings can be adjusted on the HP Digital Imaging Options dialog box: ● Contrast Enhancement. Increases image contrast for a more visually pleasing result. This filter is useful with flat images (images in which much of the content is compressed into a small dynamic range of pixel values). Flat images may result from low lighting, environmental haze, or camera or scanner limitations. ● Digital Flash. Adjusts lighting levels to reveal areas in shadow. The filter locates dark areas and brings out detail without degrading other features. ● SmartFocus. Increases the apparent resolution of lower resolution images. Many images that are downloaded from the Internet or from digital cameras can be compressed because of size restrictions and might exhibit pixilation artifacts when printed. SmartFocus upscales the image to the printer resolution without accentuating these artifacts. ● Sharpness. Improves the sharpness of an image by making the edges more prominent. The filter detects regions that contain significant variations in pixel value along a number of different vectors (which denotes edges) and then applies a filter to enhance detail. ● Smoothing. 134 Chapter 4 HP PCL 6, PCL 5, and PS Emulation drivers for Microsoft Windows ENWW
