- Resolution better than HD
In addition, it is important to know who the cameras are made for, for what purpose they serve and how you can get the most out of them.
For whom are the USB 2 cameras intended?
The USB 2 cameras are not only developed for industrial applications, but can also be used for professional and medical applications. Whether you work with microscopes in the lab, are involved in life sciences, are interested in Internet or Things or medical technology, USB 2 cameras are definitely a good option! With their compact shape and variety of models, there is such a camera for everyone.
Editing your own images with a USB 2 camera?
The ultimate goal of recording images with this camera is that you can edit the images. That’s why we explain here how date works exactly. The drivers you need to transfer the images to your computer and actually edit them are easy to find on the internet and download from different websites. Each camera contains software that allows the user to set a specific area of interest, gain, exposure time, frame rate, trigger delay and digital output (flash) delay and duration. The USB 2 cameras can be controlled using different programming languages, for example C# and C++. This way, the cameras can be easily integrated with existing software systems. Exposure, gain and white balance can be set to a certain level or the camera can adjust these parameters automatically. The software allows capturing still images in JPEG and Bitmap file formats or video in AVI format. In addition, the software can perform edge enhancement, image mirroring and image capture, in vertical and horizontal direction, as well as hot pixel correction. Direct Show (WDM), ActiveX and TWAIN drivers and SDK documentation are included. In addition to USB 2 cameras, there are also USB 3 cameras on the market. These cameras have more megapixels, can be controlled by multiple software applications and are supported by multiple different programming languages. Nevertheless, these newer cameras are also more expensive than the USB 2, so it depends on what you expect from the camera, what you want to spend on it and what programming language(s) you and your employees master.
