Global exposure and rolling shutter exposure are two mainstream shutter modes for image sensors, each with its own advantages and disadvantages in video chip applications. As a video processing chip provider, Shenzhen V-Well Technology's EM37180 series solutions support two mode switching and are suitable for security monitoring, industrial vision, and other scenarios.

The advantage of global exposure is the elimination of jelly effect, which is suitable for capturing fast-moving objects in vehicle electronics and industrial vision; The disadvantage is slightly higher power consumption and cost. Roller shutter exposure has outstanding cost-effectiveness in static scenes such as smart education and video conferencing, but it is necessary to avoid shooting high-speed objects.

The VW-3880 /VW-3880DP series USB camera solution from Shiduan Wei defaults to roller shutter exposure, making it suitable for entry-level applications;

; The EM37180 series supports global exposure mode and is used in security monitoring and other situations that require precise imaging. Please consult the manufacturer for the latest specifications for specific parameters.
