Machine Vision Camera

lastmod 2026-04-24created 2024-11-129 edits

A Machine Vision Camera is a camera used in automated vision systems to identify and analyze objects. Using image processing and analysis techniques, these cameras perform product inspection, quality control, robot vision, object recognition, motion tracking, automated inspection and measurement, and more.

Capture board vs frame grabber

Capture boards and frame grabbers perform similar functions but are used for slightly different purposes. The differences between the two devices are as follows

Capture board
Main purpose: Used to feed a video signal into a computer to capture and record the screen.
Usage: Used for game broadcasting, streaming, recording educational videos, saving video conferencing material, etc.
Main functions: Can receive external signals such as HDMI, SDI, and AV and capture them as high-quality video, and usually also supports real-time streaming.
Frame grabber
Main purpose: Used in industrial, medical, and research fields to capture images or video frames for use as data.
Usage: Captures images from microscopes, industrial cameras, inspection equipment, etc. for data analysis or quality inspection.
Main functions: Used when high-resolution image capture and high frame rates matter, and often used in high-precision image analysis and computer vision systems.

Summary:

Item

Capture board

Frame grabber

Main purpose

Game broadcasting, streaming, video recording

Image/frame capture in industrial, medical, and research fields

Usage

Capturing and streaming HDMI/SDI input video

High-resolution image capture from microscopes, industrial cameras, etc.

Main functions

Real-time streaming, video recording
