USB LISM-PI26xx – USB Line Scan Camera System
High-Precision Imaging. Modular Design. USB Simplicity.
The USB LISM-PI26xx is a compact, high-performance line scan camera system built for modern machine vision, industrial inspection, and embedded imaging applications. It offers a clean and flexible solution for acquiring high-resolution line-based image data — all over a single USB connection.
Designed for developers, integrators, and OEMs, the USB LISM-PI26xx combines a customizable sensor module with a powerful USB interface board, offering both the precision of analog control and the convenience of a plug-and-play software API. Whether you’re scanning high-speed motion or building a tightly integrated product, this system gives you full control over every aspect of acquisition — from pixel timing to trigger synchronization and analog signal tuning.
A Complete Line Scan System
At the heart of the system is the LISM-PI26xx sensor module, which supports a variety of CMOS linear image sensors and provides a configurable analog front end. Paired with the USB LISM-PI26xx interface board, the system becomes a fully host-controlled camera with real-time streaming, software-defined acquisition, and flexible hardware integration.
All configuration is handled over USB via a dedicated software API — giving you programmatic access to timing, resolution, trigger modes, gain, offset, and more. The 16-bit pixel data is streamed directly to the host computer or processor, line-by-line, without the need for a separate frame grabber or external synchronization hardware.
The sensor and interface boards are connected via a 26-pin flexible flat cable (FPC), which allows the camera head to be mounted separately from the USB board — ideal for embedded applications, tight enclosures, or systems that require mechanical isolation.
Flexible Triggering and Integration
The USB LISM-PI26xx supports a variety of acquisition modes to fit a wide range of applications. Internal free-running and software-triggered modes are available for continuous or timed imaging, while external and encoder-based triggering allows for precise synchronization with moving parts or production lines.
In encoder mode, the system can be configured to capture one line per movement step — ideal for conveyor systems or rotational scanning. Integration time, pixel clock frequency, trigger delay, and pulse widths can all be configured in software at runtime.
A programmable trigger output is also included to control external lighting, synchronize additional equipment, or close a control loop with downstream devices.
Optimized for Embedded and Industrial Use
The hardware design emphasizes compactness, modularity, and low power consumption. The interface board is powered entirely via USB 2.0, with no need for an external power supply. The sensor module measures just 48 × 38 × 7.2 mm³, making it easy to embed into devices or mount in space-constrained environments.
The system includes an EEPROM for persistent storage of configuration settings, as well as a ring buffer architecture to ensure continuous data capture — even in high-throughput environments.
Software API and Platform Support
The USB LISM-PI26xx is controlled via a dedicated software API that supports:
- Device detection and initialization
- I²C register-level communication with the sensor
- Configuration of acquisition modes and parameters
- Real-time access to image data via a circular buffer
- EEPROM read/write for persistent settings
- The SDK includes libraries for Windows (32-/64-bit DLL) with sample code. Support for Linux and Raspberry Pi is in development.
The clear, modular API design makes it easy to integrate the system into your own application — whether you’re building custom control software, automation tools, or embedded systems.
