Figure 4-12 HP Digital Imaging Options dialog box The following settings can be adjusted on the HP Digital Imaging Options dialog box: ● Contrast Enhancement. Use to increase image contrast for a more visually pleasing result. This filter is useful with flat images (images in which much of the image 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. Use to adjust lighting levels to reveal areas in shadow. The filter locates dark areas in an image and brings out detail without degrading other features in the image. ● SmartFocus. Use to increase 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. Use to improve the sharpness of an image by increasing edge detail to make 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. Used to decreases noise artifacts that are often created by digital cameras or scanners. The filter locates areas that contain abrupt changes in pixel value compared to surrounding pixels (which denotes noise) and then applies a filter to smooth the output.
