Digital Natural Image Engine : DNIe

July 4, 2009

Samsung Electronics is one among the leading players in the plasma display industry. Sharp images with life-like perfection are the major highlight of all Samsung televisions. Although many other displays come with the same specs as that of a Samsung telly, the output picture quality differs drastically. Why is it so? All credit goes to the efficacious image processing system implemented in the Samsung displays. DNIe stands for Digital Natural Image Engine, and is a natural image technology debuted by Samsung in 2003. Most of the contemporary HDTVs from Samsung come with this competent image processing system.

dnie-effects-on-pictue-quality Digital Natural Image Engine : DNIe DNIe chip was evolved during the venture of Samsung designers and engineers for improvising the picture quality of non-HD televisions. However, due to the rapid enhancement in detailing and colour saturation, it was adopted for HD televisions as well. DNIe boosts the quality of output images drastically with the help of a Four Step Process. It optimizes and enhances the image as well as sound in such a way to draw the users into a distinct world of High Definition Entertainment.

Four-Step Process

1. Motion Optimiser
This step refines the image distortions and blurs due to the fast motion sequences. DNIe curtails the noise and blurs in the frame to a great extent in its maiden stride itself. Motion Optimiser is a combination of motion adaptive techniques and temporal filtering, which helps to decrease the noise between sequential frames. It also helps to cut-short the spatioal noise in a 2D image.

2. Contrast Enhancer
Conventional contrast enhancement leaves a fading effect in the output images of televisions; hence the displayed frames will lose the natural lustre and vibrancy. In DNIe, Samsung has employed Contrast enhancer that enriches the brightness and contrast levels considerably to render bright whites and deep darks. Samsung makes use of more than a million criteria to spot out the optimal contrast to render “the best” images as output. Wicked black levels and shimmering whites are realized in Samsung HDTVs with the help of contrast enhancer.

3. Detail Enhancer
It analyses the picture signal in finesse to sharpen the frames optimally for rendering life-like video output. In Detail Enhancer, video signal elements are closely examined to render crisp images with neat image separation and graual edge transition. Many of the image enhancement processes end up giving “over-sharp” images that looks “plastic”. However Samsung has adapted intricate technology to get wind the optimal detailing and sharpness for the output images.

4. Colour Optimizer
The hues of the input video signal are analyzed closely to determine the overall brightness of the video image. The colour saturation of each scene is calculated in detail, and is optimized perfectly to render life-like images. The red, green and blue shades in the video input signals are balanced in such a way to reproduce high quality output signal with natural and realistic colours.

dnie-technology Digital Natural Image Engine : DNIe Samsung is one among the global leaders in the plasma display industry. Although, it is one among the leading image processing systems, DNIe cannot be turned off in all Samsung HD Televisions. Some among the users many have their own discretions about picture quality, and chances for disliking the DNIe is also there. Since the digital signals are manipulated in DNIe image processing system, it will be better if Samsung provides an ON/OFF option for it.
