In fields like machine vision, high-speed photography, and drone aerial photography, fast-moving objects often leave behind frustrating distortions in photos, known as the "jello effect." This phenomenon is caused by the unsynchronized exposure times of pixel rows in traditional rolling shutter cameras. However, a technology is changing all of that: Global Reset Release (GRR) mode. Muchvision is committed to integrating this technology into our high-performance camera modules to provide you with clearer, more reliable vision solutions.
What is Global Reset Release (GRR) Mode?
Simply put, GRR mode is an innovative method that allows a rolling shutter sensor to mimic the behavior of a global shutter sensor. It perfectly solves the problem of unsynchronized exposure across pixel rows through three stages:
Reset Phase: All pixel rows are reset at the exact same moment, preparing to capture a new image.
Integration Phase: All pixel rows begin their exposure at the same time, collecting light synchronously.
Readout Phase: After exposure is complete, the sensor data is read out row by row, just like a standard rolling shutter.
It is this "synchronized exposure, asynchronous readout" mechanism that allows GRR mode to drastically improve the performance of rolling shutter cameras without significantly increasing costs.
Core Advantages and Value of GRR Mode
Eliminates Image Distortion: The most significant advantage of GRR mode is its ability to effectively eliminate the "jello effect" and localized distortions that traditional rolling shutters create when capturing fast-moving objects. It provides you with stable, true-to-life, and undistorted images.
A Cost-Effective Alternative to Global Shutters: Global shutter cameras are often expensive due to their complex structure and manufacturing costs. The emergence of GRR mode offers a more cost-effective, high-performance alternative for applications with budget constraints but demanding performance requirements.
Expands the Application Scope of Rolling Shutters: High-speed motion capture and other demanding tasks were once off-limits for rolling shutter cameras. The introduction of GRR mode allows these cameras to excel in applications that require precise imaging, such as high-speed defect detection, drone photography, and sports capture.
It is worth noting that while GRR mode performs excellently in image clarity, the sequential readout can lead to uneven image brightness in certain specific environments. However, this issue can be effectively addressed with an external mechanical shutter or ambient light suppression techniques.
