Most of the DSLR cameras and mobile ’s cameras are using Rolling Shutter technology including Canon, Nikon, and iPhones, while industry cameras are using Global Shutter technology. Why cameras are so different, let’s take a look at the facts of these two kinds of technology.
If you are looking for more details, kindly visit HBVCAM.
Rolling Shutter, usually found in CMOS sensors is a method of capturing an image that does not expose the entire sensor pixels simultaneously, actually it exposures line by line from top to bottom.
Rather than the rolling shutter camera, the global shutter camera exposures all pixels at the same time. The shutter opens at a certain time then closed, blocking the light enter into the sensor.
Here is a short demonstration of how rolling shutter works in a simplified 10×10 CMOS sensor.
Most of the people think that the rolling shutter is bad. I don’t think so, it is just a kind of technology. There is no better from one than the other if you don’t compare them according to a given application. General speaking rolling shutter is good when low cost, high resolution, and high frame rate is needed, while the global shutter is good for fast moving objects and machine vision applications.
ArduCAM now introduces two global shutter camera headboard based on ON-Semi (used to be Aptina) MT9V022/ MT9V034 (0.3MP) and AR/AR (1.2MP). The camera headboard can be used with ARM, DSP, FPGA so similar platforms with parallel camera interfaces.
ArduCAM also provides USB camera shield for seamless integration for these global shutter camera board. Mono and color types are available for both types. The main spec for each sensor list below.
Send us an whenever you need any support from us.
You can download the software from our Developer Resources. Then, all you need is your Sales Order (SO) number. You may refer to question number 8 for more details about the sales order.
Please follow the below instruction.
Here's a step-by-step instruction to register and download the files from our Developer Website.
e-con Systems will provide basic support on the evaluation for all the customers who have purchased the camera. We will help in choosing the best compatible camera based on the application use case of the customer. This will help the customer to choose the right product for their system. e-con Systems will also provide hardware/software/firmware customizations like form factor, interface type, IP rating, and lens mount based on your requirements.
If you purchase any of our camera products in the online web store, we will ship them as per the lead time of the particular camera. As we use FedEx/UPS/DHL for shipping, it will take additional 3-4 business days to reach your place from the date of shipment.
For more USB Global Shutter Camera Moduleinformation, please contact us. We will provide professional answers.
A Sales Order (SO) number is a numeric code assigned to a particular request to buy our camera products. You can download the required files and software from our Developer Website using the SO number of your purchase of our camera products. Refer to question 1 for step-by-step instructions to register and download the files from our Developer Website.
Yes, e-con Systems' cameras in mass production are NDAA-compliant. We prioritize security and regulatory compliance in our camera solutions, ensuring they meet the standards outlined in the National Defense Authorization Act (NDAA). For more information, please refer to our blog post. If you have further questions or need assistance, feel free to reach out to us at .
By default, the camera is in auto exposure mode. When the scene has low-light conditions, the auto exposure algorithm will increase the exposure time, thus reducing the frame rate. You can set the maximum exposure limit using exposure compensation in the Extension Control menu or choose manual exposure to get desired frame rates. specific to the frame rate (to get 60fps, the maximum exposure time must be 1/60 => 16.66 milliseconds).
Our USB cameras are UVC-compliant and do not require any special camera drivers to be installed on the host PC. It's just a plug-and-play device. For Windows, by default, the MJPEC codec will be installed when installing e-CAMView. However, the codec might have failed to install in some cases, resulting in an MJPG stream preview. You need to install the MJPEG codec to camera streaming MJPG format. Please go to the e-CAMView installed directory "C:\Program Files (x86)\e-con Systems\e-CAMView" and install the "MJPEGCodec_RETAIL". Refer to the below image for your reference and then check the MJEPG.
Also, camera-related documents can be downloaded from our Developer Website, as mentioned in question 1.
This may be due to bandwidth limitations in the USB host. It can occur when multiple cameras are connected to a single USB host or in USB hosts of less powerful embedded boards. Read this blog for more information on USB practical bandwidths. For MJPEG, reducing the Q-Factor will improve the FPS and stability in case of any issues. If still required, reduce the frame rates.
Our USB camera has some additional controls and features, and these are not quite common controls. Hence they are not included in the standard UVC controls but are listed as UVC Extension controls. We have provided the extension unit SDK package to access the Extension Unit controls. The extension unit SDK package and API document can be downloaded from Developer Resources, as answered in question 1.
We have developed an OpenCV-based sample application v4.5.5 - OpenCVCam, a command line application for streaming and image capture, along with the support for standard UVC controls of e-con Systems' cameras in Windows and Linux.

Please refer to the installation manual to install the OpenCVCam application from here: https://github.com/econsystems/opencv/tree/master/Documents
Yes. Our USB cameras are UVC-compliant and do not require any special camera drivers to be installed on the host PC. It's just a plug-and-play device. The native UVC drivers of Linux Operating Systems shall be compatible with this camera. It should work with any direct show and V4L2 application. For more details, please refer to this blog.
In Linux, the firmware version can be obtained by using our QtCAM application. Please go to the Extension Setting tab and click on the Firmware version. In Windows, the firmware version can be obtained using our e-CAMView application. Please go to the UVC Extension menu and click on the Firmware version.
Yes. All our USB color cameras have an inbuilt ISP (Image Signal Processor). Our color camera has an onboard ISP to perform major image processing functions like debayering, WB control, Color correction and other image quality improvement features, reducing the processing load in the host platform. You could use any direct show and V4L2-based applications to access our camera.
