How the Lack of Black Level Correction Can Affect Image Quality

Prabu KumarJuly 3, 20260

The first blog in this series covered what Black Level Correction (BLC) is, the physics behind dark current and the black level offset, how that offset is measured, why sensors add a deliberate pedestal before the ADC, and how BLC interacts with each stage of the ISP pipeline from lens...

Black Level Correction in Image Sensors: What It Is and Why It Matters

Prabu KumarJuly 3, 20260

Black Level Correction (BLC) is a vital stage in the Image Signal Processing (ISP) pipeline. It is one of the components of the camera tuning process, and is usually performed after Dead Pixel Correction. BLC’s primary purpose is to remove sensor-generated offsets and noise present even without incoming light. In...

How GMSL Health Monitoring and Error Recovery in e-con Systems’ STURDeCAM Series Enhances Autonomous Mobility

Prabu KumarJune 22, 20260

GMSL technology is a high-speed and power-efficient video link commonly used in advanced driver assistance systems (ADAS), smart traffic, and robotic applications. It operates by employing serializers to convert data into a serial stream on the transmitter side and deserializers to convert it back into a parallel word for processing...

How 10GigE Industrial Cameras Enable Scalable High-Speed Automation

Prabu KumarJune 19, 20260

It’s evident that industrial imaging, these days, depends more and more on automation workflows, which introduces a lot of pressure on imaging. Cameras are expected to send richer image data and keep up with high-throughput machinery. They should also connect to host systems already running robotics, inspection, and control workloads....

How to Implement External Trigger-Based Camera Synchronization on NVIDIA Jetson Orin NX and Orin Nano

Prabu KumarJune 19, 20260

Image synchronization is essential in embedded vision applications that require precise, simultaneous capture across multiple cameras. These cameras use external triggering to capture images at the same moment when a specific event occurs, such as an object reaching a target position on a conveyor belt. The synchronized image improves inspection...

A Vision Guide to Choosing the Right MIPI Interface: D-PHY vs. M-PHY vs. C-PHY vs. A-PHY

Prabu KumarJune 9, 20260

MIPI technology has evolved through multiple versions, particularly in its physical (PHY) layers. These help enable high-speed serial communication architectures that replace traditional parallel camera and display interfaces, improving bandwidth scalability, power efficiency, and EMI performance. The MIPI physical layers: M‑PHY, C‑PHY, D‑PHY, and A‑PHY are actively used in embedded...

Understanding the Role of Temporal Filters in Time of Flight (ToF) Cameras

Prabu KumarMay 18, 20260

Prabu KumarPrabu is the Chief Technology Officer and Head of Camera Products at e-con Systems, and comes with a rich experience of more than 15 years in the embedded vision space. He brings to the table a deep knowledge in USB cameras, embedded vision cameras, vision algorithms and FPGAs. He...

Why PCIe Frame Grabbers Stand Out: Accelerating Multi-Camera Systems with Lattice CertusPro-NX

Prabu KumarMay 5, 20260

Simply put, a frame grabber is the bridge between a camera (or a group of cameras) and a computer system. It captures image streams, timestamps/synchronizes them (when needed), and delivers frames to memory in a format the application can consume. The right frame grabber is typically a function of three...

Sony IMX678 vs IMX715 vs IMX415: Which Sony STARVIS Sensor Does Your Vision System Need?

Prabu KumarMay 6, 20260

Sony’s IMX415, IMX715, and IMX678 CMOS image sensors represent successive generations in Sony’s imaging portfolio. All three sensors deliver 4K Ultra-HD (3840 × 2160) resolution but differ significantly in pixel architecture, sensitivity, and imaging performance. These sensors are widely used in industrial inspection, smart surveillance, and factory automation, where imaging

Enabling Flexible Multi-Sensor USB Cameras with Lattice CrossLink-NX FPGAs

Prabu KumarApril 29, 20260

Fixed-function USB camera chips define a rigid pipeline from sensor to output and leave no room for reconfiguration. e-con Systems has built a USB camera solution on Lattice Semiconductor's CrossLink-NX33U FPGA that replaces that constraint. The result eliminates the need for separate ISP chips, external USB controllers, and multiple PCBs
