LN-320 (IMX307) Technical Overview
1/2.8-Inch CMOS Sensor Module with Multi-Interface HD Output
The Lntech LN-320 is a high-definition camera core module designed
for integration into professional security systems, industrial
imaging, and OEM equipment. It employs a Sony IMX307 1/2.8-inch CMOS sensor to deliver 1080p resolution video at 30 frames per second. A key feature is its multi-format video
output, providing HDMI, HD-SDI, and CVBS signals concurrently. With advanced image processing including 120dB Wide Dynamic Range and configurable SENS-up for low-light scenarios, it offers a balanced solution for a
variety of demanding imaging applications.
In-Depth Technical Analysis
1. Sensor Architecture and Performance
The module is built around the Sony IMX307, a back-illuminated CMOS sensor known for its high sensitivity and
low noise. With an effective resolution of 1845 (H) x 1097 (V) pixels, it provides a true 16:9 HD image. The 3.75µm pixel size contributes to its excellent light-gathering capability, making it
suitable for a wide range of lighting conditions.
2. Multi-Interface Output Strategy
The LN-320 is equipped with three distinct video outputs to
maximize compatibility:
HDMI: Provides a pure digital signal for direct connection to monitors
and modern recorders.
HD-SDI: Offers a broadcast-standard uncompressed signal suitable for
long-distance transmission over coaxial cable.
CVBS: Supplies a standard-definition analog signal for integration with
legacy equipment or as a backup feed.
3. Advanced Image Processing Capabilities
Wide Dynamic Range (120dB): Utilizes multi-exposure digital processing to balance extreme
lighting differences within a single frame, preserving details in
both highlights and shadows.
Low-Light Enhancement (SENS-up): Allows for frame accumulation with settings from x2 to x32, significantly boosting sensitivity in dark environments at the
potential cost of motion blur.
Exposure & Gain Control: Features automatic and manual shutter control (from 1/60s to 1/30,000s) and adjustable AGC (0-10 steps) for precise exposure management.
4. System Integration Notes
The standard CS lens mount ensures compatibility with a vast array of commercial lenses.
Image parameters such as Sharpness, DNR, BLC, HLC, and Mirroring are fully adjustable, typically via an On-Screen Display menu
controlled through a serial interface like RS-485.
The compact form factor (133.4x69x64.5mm) is designed for easy integration into various housings.
