Introduction

The advancement of image sensor technology has led to a significant increase in high-resolution and ultra-high-resolution OEM cameras from machine vision suppliers. These developments, coupled with lower production costs driven by consumer markets, have expanded options for demanding inspection applications such as flat panel inspection, PCB inspection, wafer and component inspections.

System designers can leverage higher resolution cameras to improve field of view (FOV), measure smaller details, and increase throughput. However, selecting the appropriate camera involves more than just considering resolution; numerous technical parameters must be evaluated based on specific application requirements.

Key Considerations in Camera Selection

Resolution vs. Frame Speed

While resolution is a critical factor, it’s essential to balance this with frame speed for optimal system performance. Higher resolutions generate larger data volumes that require substantial processing power and sophisticated optics – elements that may not always be justified by the increased pixel count alone.

Pixel Pitch and Field of View

When replacing multiple cameras with fewer units or implementing high-resolution solutions, designers must consider pixel pitch and optical format compatibility to ensure seamless integration without compromising image quality or system functionality.

Sensor-Specific Optimization

Different image sensors excel in various performance characteristics:

  • Read noise optimization
  • Full well capacity management
  • Frame rate capabilities
  • Advanced imaging functions

Camera manufacturers implement additional design choices beyond sensor selection, including:

  • Image enhancement algorithms
  • Processing architecture
  • Interface protocols
  • Thermal management systems

Camera-Specific Case Studies

Adimec QUARTZ Q-12A65 (12 Megapixel)

This CMOSIS CMV12000-based camera offers 12 megapixels at 75 full frames per second over Camera Link. Its key strengths include:

  • Exceptional sensitivity for low-light applications
  • Robust dynamic range capabilities
  • Superior shutter performance for high-speed metrology

Advanced features such as Active Sensor Control with local/global Flat Field Correction (FFC) enhance image quality across varying temperature conditions without requiring additional tooling.

Adimec Sapphire S-25A30 (Vita 25k)

This alternative solution provides:

  • Flexible ROI implementation
  • Configurable resolution reduction capabilities
  • Excellent shot noise performance

Selection Process Recommendations

The camera selection process requires a systematic approach:

  1. Define precise application requirements before reviewing specifications.
  2. Consult with camera suppliers to understand design trade-offs and technical constraints.
  3. Test potential cameras under actual operating conditions, as simulated parameters often don’t reflect real-world performance.

This methodical evaluation ensures alignment between system capabilities and operational demands while avoiding costly implementation errors or suboptimal performance in critical industrial applications.
