Executive Technical Summary
A single-exposure HDR camera is an imaging system designed to capture full dynamic range information within one frame instead of combining multiple exposures. This approach eliminates motion artifacts such as ghosting and alignment errors, making it particularly suitable for high-speed industrial inspection and monitoring environments.
Engineers typically select single-exposure HDR sensors when scenes contain strong contrast, moving objects, or reflective materials. Performance evaluation focuses on exposure stability, frame timing consistency, dynamic range behavior, and integration reliability rather than resolution alone.
Executive Summary: Why Choose IMX678 in 2026?
The Tech Jump: The IMX678 utilizes STARVIS 2 technology, delivering a 2.5x wider dynamic range and significantly better NIR sensitivity than the previous generation (IMX415).
Larger Pixels: A 1/1.8" sensor format with 2.0μm pixels ensures superior Low-Light Performance and lower noise.
Best Use Cases: High-fidelity Medical Microscopy, Smart Traffic Systems (LPR), and Premium Video Conferencing.
Why Single-Exposure HDR in the IMX678 is a Game-Changer for Industrial Monitoring
In modern industry, speed and precision are everything. Yet when vision systems cannot keep up, efficiency suffers. High-contrast environments—bright factory lights alongside deep shadows, trucks entering dark warehouses from sunlit exteriors—pose one of the toughest imaging challenges. For engineers, clarity is the difference between streamlined workflows and costly downtime.
Traditional HDR (high dynamic range) cameras have long promised a solution, but in fast-moving environments, they introduce a new problem: motion artifacts. Ghosting, blur, and unreliable recognition are unacceptable in high-stakes industries.
This is exactly why Sony STARVIS 2 IMX678 USB Camera Module redefines the standard. With single-exposure HDR, it captures sharp, artifact-free 4K detail in every frame—no matter how fast the object moves or how extreme the lighting contrast.
Our USB camera with single-exposure HDR is designed for real-world industrial integration, bridging cutting-edge sensor performance with plug-and-play hardware usability.
Industrial Vision Trends in 2026
Industrial monitoring systems are increasingly shifting toward edge-based processing, where image data is analyzed locally instead of being transmitted to remote servers. This transition requires cameras that deliver consistent image quality, predictable timing, and minimal latency.
As automation systems integrate AI-driven perception, imaging modules must perform reliably across variable lighting conditions and motion scenarios. Cameras capable of maintaining detail in both bright and dark regions are therefore becoming essential components in modern inspection pipelines.
Together, this makes our product not just a sensor board, but a machine vision camera integration service-ready module.
Bandwidth and Streaming Considerations
Streaming high-resolution video depends on both interface bandwidth and host processing capability. When operating at higher resolutions or frame rates, compression format, USB controller performance, and system resources may influence sustained streaming stability.
For validation, engineers typically test continuous streaming duration, frame consistency, CPU utilization, and thermal behavior under real operating conditions.
The STARVIS 2 Advantage: IMX678 vs. IMX415
Why Upgrade Your Vision System?
In 2026, the IMX415 is still a capable sensor, but the IMX678 is the new king of 4K.
Bigger is Better: The move from a 1/2.8" sensor (IMX415) to a 1/1.8" sensor (IMX678) allows for 2.0μm pixels. This physically captures more photons, resulting in brighter, cleaner images in dim environments.
Power Efficiency: STARVIS 2 architecture reduces power consumption by ~30%, critical for battery-operated medical handhelds or edge AI boxes to prevent thermal throttling.
Enhanced NIR: Sensitivity in the Near-Infrared range (850nm/940nm) is boosted, making it ideal for "Zero-Lux" surveillance where discreet IR lighting is used.
Older HDR technologies (e.g., DOL-HDR) work by merging multiple frames of varying exposures. Imagine taking a dark shot for highlights and a bright shot for shadows, then blending them. In static scenes, this works.
But in motion—cars, forklifts, conveyor belts—the frames misalign. The result: ghosting artifacts, blur, and unusable data.
For industries, this means failed barcode scans, unreliable license plate recognition, and flawed quality control, leading to downtime and compliance failures.
Artifact-Free HDR for Moving Subjects
Solving the "Ghosting" Problem
Traditional DOL-HDR (Digital Overlap) takes two exposures sequentially, which often causes "ghosting" artifacts if the object moves between frames. The IMX678 supports advanced Clear HDR (and single-exposure HDR modes tailored by our ISP), which significantly reduces these artifacts. This makes 4K HDR finally viable for monitoring moving assembly lines or walking pedestrians where older cameras failed.
Engineering Perspective on Single-Exposure HDR
Unlike multi-frame HDR techniques that merge several exposures, single-exposure HDR captures the entire scene in one sensor readout. This eliminates alignment errors between frames and prevents motion artifacts when objects or cameras are moving.
For high-speed inspection systems, this design improves measurement stability, reduces processing complexity, and ensures consistent image data for downstream analytics.
Why Dynamic Range Matters in Industrial Vision
High dynamic range improves detection reliability in scenes where bright and dark regions coexist. In real environments such as factory entrances, conveyor systems, or outdoor checkpoints, lighting contrast can vary significantly.
Cameras capable of capturing detail across this range provide more usable visual data for recognition algorithms and reduce the need for manual exposure tuning.
The IMX678 Starvis 2 usb camera captures highlights and shadows simultaneously, within one exposure.
For industries needing stop motion blur in HDR video, the IMX678 is the definitive solution.

Can HDR reduce detection errors in high-contrast scenes?
Yes. By preserving detail in both bright and dark areas, HDR improves feature visibility for recognition systems.
Is higher resolution always necessary for industrial inspection?
Not always. Stable exposure and consistent frame timing often contribute more to reliable detection than resolution alone.
How do engineers evaluate camera stability?
They typically measure frame consistency, exposure behavior, and long-duration streaming reliability.
What causes ghosting artifacts in HDR imaging?
Ghosting occurs when multiple exposures are merged while objects move between frames.
Does lighting variability affect camera selection?
Yes. Lighting conditions directly influence required sensitivity, dynamic range, and exposure behavior.
Q: "Does the IMX678 USB module support 4K at 60fps?"
A: The sensor hardware supports it, but the USB 3.0 bandwidth limit typically caps 4K (3840x2160) transmission at 30fps (MJPEG/H.264). For true uncompressed 4K@60fps, we recommend our MIPI CSI-2 version of the IMX678. However, our USB module offers smooth 60fps at 1080P, which is ideal for low-latency video streaming.
Q: "Is this camera compatible with NVIDIA Jetson Orin for Edge AI?"
A: Yes. Our USB 3.0 IMX678 modules are fully UVC Compliant. On NVIDIA Jetson (Jetpack 5.x/6.x), they are recognized immediately as /dev/video0. You can ingest the video stream directly into DeepStream, GStreamer, or OpenCV for YOLO inference without compiling custom kernel drivers.
Q: "Can I get a custom lens mount (C-Mount / CS-Mount)?"
A: Yes. While the sensor is large (1/1.8"), we offer housings with C/CS Mount adapters. This allows you to use professional varifocal lenses for traffic monitoring or telecentric lenses for lab work, maximizing the sensor's optical potential.
