NightMerge: Denoise-then-Merge Low-Light HDR SDK for Security Cameras

Software for security cameras that turns grainy night footage into clear, colorful images.

A licensable firmware module for security camera OEMs: each bracketed long exposure is wavelet-denoised, the set is merged into an HDR radiance map, and an adaptive-gain tone map produces a readable color night image instead of grainy single-exposure or IR-only footage.

Concept

A drop-in imaging module (SDK/firmware) for security camera manufacturers that replaces noisy single-exposure night modes or monochrome IR-only footage with a readable color night image from the same sensor. Pipeline: (1) capture a short bracket of long low-light exposures; (2) de-noise each frame with multiscale wavelet shrinkage (soft and hard thresholding); (3) merge the cleaned frames into an HDR radiance map; (4) tone-map with nonlinear adaptive gain that restores contrast within structures and along boundaries. The result is a standard video frame in which a porch light no longer blooms into a white disc and the dark yard is no longer buried in noise. OEMs integrate it as a 'night mode' on existing camera SoCs — no new sensor required.

Why now

Paper [5] demonstrates a wavelet framework that jointly reduces noise via soft/hard-thresholding shrinkage and enhances contrast within structures and along boundaries — precisely the per-frame cleanup that long low-light exposures need. Paper [0] shows that the HDR capture-to-radiance-map-to-tone-mapping pipeline is now a codified, practical discipline with equations and reference code, born of the last decade's unification of photography and computer graphics. Security camera vendors compete directly on night performance, and most still ship IR-only monochrome night modes; combining these two established techniques into a drop-in module is an engineering integration task, not a research risk.

A pragmatic integration of established HDR and wavelet denoising techniques into a B2B SDK for security camera OEMs to replace IR-only night modes.

Evidence strength
4/5
The idea relies on two well-documented pillars: a codified HDR pipeline and a specific wavelet-based denoising/contrast framework, making the technical path clear.
Market pull
4/5
Security OEMs have a high incentive to improve night-time color fidelity to compete on image quality, and the named beneficiaries are the primary market leaders.
Novelty & moat
3/5
While HDR and denoising are common, applying this specific combined pipeline as a drop-in firmware module for surveillance is a distinct application compared to the aesthetic/scientific tools in the catalog.
Feasibility
3/5
The math is established, but implementing this as a real-time firmware module on constrained camera SoCs requires significant optimization of the wavelet transforms.
Wedge clarity
5/5
The wedge is extremely sharp: a licensable 'Night Mode' SDK for existing camera hardware.
Simplicity / focus
5/5
The product is a single, focused imaging pipeline with one clear value proposition: better night color.

Who benefits

  • Axis Communicationscompany

    The premium camera OEM markets low-light color performance as a headline differentiator; a color night mode built from wavelet-denoised HDR brackets strengthens exactly that positioning.

  • Verkadacompany

    The cloud-managed camera vendor ships features via software updates, so a licensable night-mode module is a natural software-defined upgrade across its installed base.

  • Bosch Security and Safety Systemscompany

    A professional surveillance camera OEM competing on image quality; a drop-in night imaging module improves its offering without new sensor hardware.

  • Hanwha Visioncompany

    A high-volume surveillance camera maker; a differentiated color night image from existing hardware adds margin without hardware redesign.
