e-con Systems has developed, customized, and deployed cutting-edge global shutter cameras - partnering with the world's leading sensor technology providers like Sony, onsemi and OmniVision. Our range of Global Shutter cameras ensures a High Frame Rate (up to 280 fps) to power your embedded vision applications.
With competitive price and timely delivery, HBVCAM sincerely hope to be your supplier and partner.
When a camera is on global shutter mode, the image sensor allows the sensor's pixels to start exposing and stop exposing simultaneously for the programmed exposure period. At the end of the exposure time, the pixel data readout begins - proceeding row by row until all pixel data has been read. Global shutter sensors are popularly used in applications that need to capture high-speed moving objects.
When on rolling shutter mode, artifacts are caused since every row in a frame is exposed at different times. The exposure of consecutive rows starts sequentially - resulting in deformations (or rolling shutter artifacts) in the output image while capturing moving objects. Conversely, the global shutter mode uses a mechanism that produces non-distorted images without wobble or skewing.
If you are interested in knowing more about how to choose the shutter type that suits your application, please visit this article: 'What are Global Shutter and Rolling shutter Cameras? How to choose the one that fits the application?'
Please watch the below video for a quick overview of the two camera shutter types:
As mentioned above, rolling shutter artifact occurs in the output image when the object moves too fast within the exposure time, and its position varies between the start and end of exposure times. The higher the exposure time or speed of the target object, the higher the artifacts. A global shutter camera can capture images in a single moment of time. There's no need for rolling or scanning, as with the rolling shutter. Hence, it can eliminate skewing and distortions in the captured images. It is used in applications like autonomous mobile robots, smart traffic management systems, warehouse & factory automation, etc.

Hi, yes, but our driver doesn&#;t support it. You have to manually do register writes to the camera for this. You can do this all through the Python API but you need to read the sensor data sheet to achieve what you want.
Please go the product page and see the sensor data sheet. Then find the mt9v034.c file in our code repo. Under the set frame size method you can see how we set the image read out size and turn pixel binning on as you lower the resolution.
So, you just need to run the set frame size code that you&#;d execute like normal and then after do a series of register writes to move the ROI of the camera readout to what you want to look at. This will give you a very high fps without any binning.
If you get this working please share the code and we my and an example to the IDE for this.
