Pinnacle Imaging Systems launches Denali-MC HDR ISP IP core said to preserve a scene’s color fidelity and full contrast range throughout the tone mapping process, all without producing halos, color shifts, and undesired motion artifacts.
Denali-MC 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, including 9 Aptina/ON Semi, 6 Omnivision and 11 Sony sensors, and 12 different pixel-level gain and frame-set HDR methods, and is said to be easily ported to the most widely-used logic platforms.
HDR-Specific Features:
“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.”
“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.”
Pinnacle also publishes a video demo of its HDR capabilities (short version, long version):

HDR-Specific Features:
- Advanced motion compensation algorithms virtually eliminate HDR merge artifacts and transition noise
- Proprietary Locally Adaptive Tone Mapping technology preserves color fidelity through the entire tonal range without creating halo artifacts or color shifts
- Automatic EV bracketing
- Automatic or manual contrast adaptation for global or local video correction
- React concurrent still frame and video capture feature, non-destructively extracts four source LDR Bayer images, merged Bayer HDR, tone mapped Bayer or HDMI RGB still frames without interrupting video
- Ability to capture separate HDR and tone mapped output video streams concurrently (ideal for ADAS applications)
- Two or four frame multiple exposure merge (with Sony IMX290 implementation)
- HDR + Low illumination capabilities with Sony IMX290 sensor enable 24/7 round the clock video capture capabilities for any contrast and lighting condition
