HDR10/HDR10+ Tone Mapping, smooth gaming 

Pixelworks recently scored a strategic agreement with HDM Nokia and just days before MWC the company announced its 5th generation Iris. Now, the company announced its next generation power efficient premier processor for mobile devices.

It is all about getting the mobile display processing technology, SDR to HDR conversion and smooth blur-free motion in gaming to the next level.

Pixelworks’ Iris 5 display processor enables stunning new visual experiences for smartphones at a fraction of the power consumption of previous generations in order to prepare for 5G inspired video consumption and gaming.

The Iris 5 dramatically improves video and image quality for LCD and OLED displays with refresh-rates of up to 120Hz, the newest Pixelworks chip offers OEMs a full suite of industry-leading features to visually differentiate a broad range of mobile products, including smartphones, gaming devices, and tablets.

Brings HDR 10+ to mainstream

This is the first Pixelworks chip to support HDR10+, which uses metadata that allows HDR tone mapping to adapt dynamically, scene-by-scene, for optimal black levels and peak brightness.

The Iris 5 chip also incorporates significant advancements to Pixelworks’ unique TrueClarity motion processing by adding adaptive intelligence and reducing power consumption by more than 50 percent, compared to the previous generation.

Leveraging built-in custom tuning capability, the system claims to mitigate judder and strobing effects that result from the differences between content frame rates and display refresh rates, while suppressing the undesirable "soap opera" effect associated with alternative approaches. TrueClarity technology is more advanced and more power-efficient than any motion processing solution currently available.

Pixelworks’ Iris 5 product (PX8568) is being unveiled in conjunction with Mobile World Congress 2019 in Barcelona, and the company anticipates sampling the chip during the first quarter in support of commercial mobile device launches in the second half of 2019.

The Pixelworks Iris 5 processor comes with the following features:

  • TrueClarity Smart Motion Processing adaptively removes artifacts that distract from movie storytelling, gaming and live sports, for blur- and judder-free viewing
  • HDR10/HDR10+ Tone Mapping provides cinematic-quality HDR playback that is true to the creator’s intent and facilitates certification by leading providers of HDR content
  • Realtime SDR to HDR Conversion transforms SDR videos and games to HDR quality with richer detail and color tonality
  • Multi-adaptive Display provides optimal viewing in all lighting conditions, with modes for Day Light View (DLV), Night View, Color Tone and Reading Mode for eye comfort
  • Local Contrast Enhancement offers best-in-class contrasting that exposes hidden texture in dark areas while retaining detail in bright regions of an image for uniformly superior display quality
  • Absolute Color Accuracy builds on Pixelworks’ industry-leading color calibration, enabling delta E<1, improved flesh tone, comprehensive color management and custom tuning

“We are excited to release the most feature rich and advanced version of our visual processor into a mobile market environment where consumers are seeking the ultimate visual experience”, said Anthony Gioeli, Pixelworks’ Executive Vice President and General Manager, Video Devices. “Visual display experience is more than a collection of pixel counts and frame rates. It is a delicately balanced collection of dynamic features and capabilities. The Iris 5 chip is the culmination of five generations of advanced visual processing research, refinement and tuning. Our enhanced portfolio of visual procession solutions provides mobile OEMs compelling differentiation and efficiency for all tiers of the market.”
