What is Local Contrast Enhancement of BenQ HDR-PRO?

As HDR technology has become immensely ubiquitous, there are more and more TV sets, monitors, and projectors with an HDR badge on them. But the truth is, with different display devices, the definition of HDR might vary. In particular, the use of contrast enhancer technology on display application is entirely different from that on a projector. Therefore, the contrast tuning is much harder and requires more professional know-how. Furthermore, compared with TVs, the way projectors screen a video to the audience is actually closer to projectors in cinemas.

By analyzing the histogram information of an image, regular contrast enhancing methods compute the level curves required for contrast enhancement to achieve a global contrast-enhanced effect. However, contrast enhancement and presentation of details are always a trade-off. The HDR-PRO contrast tuning technology of BenQ is a leading technology in the industry in providing local contrast enhancer, in which each image is divided into over 1,000 regions for the application of local contrast enhancement algorithm.

Based on the aforementioned technological theories, the contrast effect produced by the local contrast enhancer has a higher degree of stereo perception compared with the general contrast enhancer. Sharpness of images is also enhanced. As a company which consistently pursues high-quality video displays, BenQ uses imagery contrast know-how to enhance its HDR-PRO technology. Via professional tuning of ISF and THX certified engineers, BenQ creates darker black level and more optimized contrast details, and optimizes contrasting stereo perception with its leading exclusive technology. This will provide audio-video enthusiasts a richer 4K HDR image depth.

BenQ is committed to recreating authentic colors of images with the utmost clarity, and enhancing its dynamic contrast performance. This allows consumers to see videos in the comfort of their home that are closest to either what movie directors intend to present, or watching films in cinemas.
