The **DFK33GR0234** is engineered with a 1/2.6-inch color CMOS sensor delivering 2.3 megapixels at a 16:10 aspect ratio. This resolution and aspect ratio provide excellent detail and a versatile field of view for various inspection scenarios. The global shutter technology is a defining feature, capturing all pixels simultaneously to eliminate motion artifacts that are particularly problematic in color imaging. With a 50 fps frame rate and GigE interface, it offers a balanced package for high-quality, dynamic color inspection.
Global Shutter: องค์ประกอบสำคัญสำหรับภาพสีเคลื่อนที่
การมี Global Shutter ใน **DFK33GR0234** สร้างความแตกต่างอย่างชัดเจนสำหรับงานภาพสีทุกประเภทที่เกี่ยวข้องกับการเคลื่อนที่ กล้อง Global Shutter จับภาพทุกพิกเซลในเซ็นเซอร์พร้อมกันในเวลาที่แน่นอน ซึ่งหมายความว่าข้อมูลสีแดง เขียว และน้ำเงินสำหรับวัตถุที่กำลังเคลื่อนที่ถูกรวบรวมในเวลาเดียวกันอย่างสมบูรณ์ ส่งผลให้ได้ค่าสีที่ถูกต้องและรูปทรงที่แม่นยำโดยไม่มีปรากฏการณ์ Color Smear หรือ Geometric Distortion
For color machine vision, the global shutter in the **DFK33GR0234** is more than just a feature; it’s a necessity for accuracy in dynamic environments. It prevents the temporal color misalignment that can occur with rolling shutters, where different color rows are exposed at slightly different times as an object moves. This ensures that color-based decisions—whether for sorting, verification, or defect detection—are made on data that accurately represents the object’s true color and shape at a specific moment, even at high speeds.
The 2.3MP resolution provides a richer dataset for color analysis algorithms. More pixels per color region lead to more statistically robust color measurements, reducing the impact of noise and improving repeatability. This is crucial in applications like food sorting (where color indicates ripeness), pharmaceutical packaging (where color verifies correctness), or any task requiring precise color matching. The additional vertical pixels (compared to 1080p) offer practical benefits for portrait-oriented inspections or when additional vertical context aids in decision-making.
Operating at 50 fps, the **DFK33GR0234** provides a responsive capture rate that aligns well with many industrial cycle times. This frame rate, combined with the global shutter, means there is minimal lag between an event occurring and its capture, and each captured frame is geometrically and chromatically accurate. This reliability is essential for inline inspection systems where every product must be checked, and a missed or distorted image could mean a defective product passing through.
The GigE Vision interface efficiently handles the substantial data throughput required by the **DFK33GR0234**. It leverages standard, cost-effective network infrastructure, allowing for easy integration into existing factory networks or the creation of dedicated vision networks. The long cable runs (up to 100m) provide flexibility in camera placement. Features like Power-over-Ethernet (PoE) can further simplify installation by delivering power through the data cable, reducing wiring complexity and cost.
This camera’s combination of attributes makes it ideal for demanding color inspection tasks across industries. In pharmaceuticals, it can verify colored pill coatings on high-speed filling lines. In automotive, it can inspect colored wire harnesses or connectors on moving assemblies. In consumer goods, it can check label position and color on bottles zipping by. Anywhere color is a critical quality attribute and products are in motion, the **DFK33GR0234** provides a reliable solution.
The **DFK33GR0234** positions itself as a compelling value proposition in the 2.3MP global shutter color camera segment. It delivers the critical combination of resolution, color accuracy, and motion-freeze capability that many inspections require. While some competitors may offer marginally higher specifications in one area, the **DFK33GR0234** provides a well-rounded, reliable package from an established vendor. This often translates to lower total cost of ownership when considering integration ease, software compatibility, and long-term support.
Optical and illumination quality are paramount for the **DFK33GR0234**. A high-resolution lens with good color correction (apochromatic or achromatic design) is necessary to fully utilize the sensor’s capabilities without introducing color fringing. Lighting must be uniform and spectrally stable; variations in color temperature will directly affect the color values captured by the camera. Using controlled, diffuse LED lighting with a high Color Rendering Index (CRI) is strongly recommended for consistent and accurate color imaging.
