“Pinnacle’s work in HDR and motion-artifact compensating algorithms is becoming well known and their HDR ISP development is state of the art,” said Bill Pu, CEO Leopard Imaging.
Belmont, C.A. (PRWEB) August 16, 2017
Today, Pinnacle Imaging Systems(TM), announced the launch of its proprietary, Denali-MC(TM) camera-ready HDR Image Signal Processor (ISP) IP core. This next generation HDR video capture technology relies on Pinnacle Imaging’s advanced algorithms to accurately tone map high contrast scenes while minimizing HDR motion artifacts. The Denali-MC HDR ISP is able to render vastly greater shadow and highlight data from a high contrast scene making it an ideal integration for camera designers seeking to optimize image detail for surveillance cameras, automotive ADAS cameras, intelligent traffic systems, commercial drones and machine vision systems.

Industry Applications and Validation
The Denali-MC HDR ISP cores are adapted from Pinnacle Imaging’s patented HDR technology modeled on true human vision. The technology ensures preservation of a scene’s true color fidelity and full contrast range throughout the tone mapping process, all without producing halos, color shifts, undesired motion artifacts, or requiring external logic. Denali-MC is able to streamline HDR deployment for developers, reducing hardware costs in the process.
“At Fairchild Imaging, we have been very impressed with the Denali-MC ISP state of the art locally adaptive tone mapping (LATM) functionality,” said Vern Klein, Director of Sales and Marketing Fairchild Imaging. “I’ve seen first-hand how they can make a great sensor perform even better in its native WDR mode. Camera manufacturers will benefit from this technology, which provides high quality HDR functionality without requiring companion chips or additional hardware cost to support the algorithms.”
As the demands on video analytics become more complex, whether by end users or integrated autonomous systems, Denali-MC’s locally adaptive tone mapping technology directly results in more detail for surveillance video, intelligent traffic systems, commercial drones, machine vision, and body-worn cameras. For image analysis purposes, the rich source data can help improve automotive advanced driver systems, autonomous vehicle development, machine vision, and more.
“Pinnacle’s new Denali-MC HDR ISP is a significant achievement addressing HDR video requirements in surveillance, monocular camera automotive markets and machine learning with its customization, artifact compensation, color accuracy and quantifiable high dynamic range of 100 dB,” said Paul Gallagher, image sensor industry veteran and futurist. “Camera system developers in these markets would benefit from utilizing these attributes of the Denali-MC ISP as a standalone ISP or integrate Pinnacle’s HDR IP blocks within their existing ISP.”
Key Features of the Denali-MC HDR IP Core
For engineers and camera designers seeking to deliver the highest-quality video content, Denali-MC instantly provides a 16-bit data path capable of producing 100 dB or 16-EV steps of dynamic range. Denali-MC HDR IP completely eliminates halo artifacts and color shifts, and mitigates the ghost artifacts and transition noise often seen when merging multiple exposures. This allows Denali-MC to capture up to four exposure frames from 1080p video at 120 fps, while merging and tone mapping at 30 fps in real time. For applications requiring faster output frame rates, Denali-MC also supports a two frame merge mode exporting at 60 fps. Furthermore, Denali-MC can support up to 29 different CMOS sensors, 12 different HDR modes and is easily ported to the most widely-used logic platforms.
Integration with Third Party ISPs
While Denali-MC is available as a complete camera ready ISP, Pinnacle Imaging’s Merge and Tone Mapping HDR IP cores can also be easily integrated into third-party ISPs making it ideal for developers and engineers seeking a stand-alone HDR solution for their existing imaging pipeline. The merge block accepts raw Bayer data as input and provides tone mapped Bayer data back to the ISP.
“Pinnacle’s work in HDR and motion-artifact compensating algorithms is becoming well known and their HDR ISP development is state of the art," said Bill Pu, CEO Leopard Imaging. "Their new Denali-MC HDR ISP surpasses any other ISP I am aware of regarding its flexibility to be customizable and extensible to support many different sensors, logic and modes of HDR and over-all video quality.”
Currently, available configurations have been developed for Xilinx® Zynq® FPGA platforms. Pinnacle Imaging is also able to provide customizable IP blocks for Altera/Intel and other FPGA platforms as well as ASIC implementation.
