Vision Sensors are sensor devices that capture visual information and convert it into electrical signals for further processing. They typically integrate an image-sensing element with supporting circuitry to acquire and output image data in a form suitable for electronic systems.

Within the broader Sensors category, vision sensors focus on detecting and representing scene content such as brightness and spatial patterns, enabling machine-readable imaging and optical measurement functions.

• Core function: Convert incident light into structured image signals.
• Common implementations: Solid-state image sensors and related vision-sensing modules.
• System role: Provide visual data as an input source for downstream processing and control.
