DNIe is a “natural image” technology introduced by Samsung in 2003. Originally developed as part of a concerted effort by Samsung to improve television picture quality on non-high-definition-televisions, the DNIe chip is now used in Samsung's plasma and high definition televisions (HDTV). DNIe offers better detail than conventional televisions by using four proprietary processes that optimize and enhance image quality and sound: a Motion Optimizer that is a noise processing technology used to eliminate blurring and noise in moving images; a Contrast Enhancer that offers rich details and image quality; a Detail Enhancer that automatically analyzes the picture signal and reproduces images that result in lifelike video; a Color Optimizer that analyzes the video signals being generated so that the quantities of reds, greens, and blues are calculated to provide natural, realistic colors.

The digital natural image enhancement (DNIe) chip was first released by Samsung in 2003 as part of the company's concerted effort to improve picture quality on standard (non-HDTV) televisions. Now used in Samsung's plasma, LCD, and HDTVs, DNIe renders images in a more natural, lifelike manner.

"The secret of DNIe TM begins with an Intelligent Analyzer that analyzes any kind of input signal to optimize the picture quality. By analyzing the frequency characteristics of the input signal, the Analyzer automatically detects the amount of noise in the signal, identifies the source level as analogue, SD, or HD, and even determines whether it has been scaled."

"DNIe generally improves most HD and DVD content with a few exceptions, but it's a mixed bag with NTSC sources. Many HD and DVD images are made sharper with DNIe, contrast is improved, and color accuracy is enhanced in many scenes." [Extremetech.com]

"DNIe is Samsung's image "enhancement" engine...On the surface these claims sound great, but on closer examination most of these features are either impossible (6 times density enhancer) or undesirable (dynamic contrast ratio). For every image DNIe makes better there are two images that it makes worse. There is no way these sets can hold a calibration with DNIe enabled. If accuracy is desired DNIe should be turned off and left off. On the HLP DNIe can be easily disabled in the user menu. It should be noted that there are a few models of Samsung DLPs (notably the HLR series) that have DNIe permanently enabled. Before purchasing a Samsung display I would make sure that DNIe can be toggled from the user menus." [Gadgetbench.com]

"DNIe is a video enhancer that makes the picture more colorful and lifelike. You can tell too. In the DNIe product demo, the screen is split - one side shows natural footage, the other shows DNIe enhanced footage. The difference is remarkable. The natural footage is boring and robbed of color while the DNIe footage is bright and crisp. The user controls when DNIe is used, which is good because not everyone will want enhanced video all the time – like an editor previewing footage to see what color correction is required."
