5. Microscopes: USB cameras are frequently integrated into microscopes, enabling researchers, scientists, or medical professionals to capture and analyze microscopic images. These cameras provide a convenient way to digitally record and study samples.

The convenience of USB cameras extends beyond consumer cameras. They are the first choice in many embedded vision systems even today. Since our topic of interest is the application of USB cameras in embedded vision, we will discuss USB cameras, USB camera modules, USB Video Class (UVC), and related topics from that point of view.

On the other hand, in the embedded camera world, the terms “USB camera” and “USB camera module” are sometimes used interchangeably, but there is a technical distinction. A USB camera, in this context, refers to a complete camera system that includes the lens, sensor array, baseboard, adaptor board, and sometimes an Image Signal Processor (ISP) and enclosure. It is a fully integrated solution that can be directly connected to an embedded vision device or system.

Choose between rolling or global shutter options to capture precise and accurate images in any application. With a range of resolutions from 1MP to 13MP, you can select the perfect camera for your specific requirements.

While modern embedded vision systems mostly use USB3 cameras since they offer high transfer rates, there could be some applications where USB3 is overkill and USB2 cameras are more suitable (because of lower cost). Examples of such applications include vending kiosks, video conferencing systems, digital signage, biometric devices, and assistive devices.

USB cameras find applications in various embedded vision devices. Their versatility, ease of integration, and compatibility make them a popular choice for capturing and processing visual data. Here are some popular use cases where USB cameras are commonly employed:

4. Document cameras: USB cameras are integrated into document cameras or visual presenters used in classrooms, offices, or conference rooms. These cameras capture images or live videos of documents, objects, or whiteboards, which can be projected or shared in real-time.

USB cameras provide a reliable and versatile solution for capturing and processing visual data in embedded vision systems. In addition to universal compatibility reasons, other reasons that USB cameras are highly preferred include:

One of the standout features of these cameras is their seamless integration into your system. With driverless functionality, they work effortlessly with Linux or Windows 10/11 operating systems, saving you time and effort during the setup process.

6. Skin scanning devices: USB cameras find applications in skin scanning devices used in dermatology and cosmetics. These cameras capture high-resolution images of the skin for identifying lesions, analyzing texture & moisture levels, and even diagnosing cancer.

One of the standout advantages of USB cameras is their simplicity. With a USB interface, these cameras can be effortlessly plugged into almost any system or device without the need for additional drivers or complex setup procedures. This “plug-and-play” feature allows users to quickly and conveniently integrate USB cameras into their existing setups, saving time and eliminating compatibility concerns.

3. Telemedicine: In telemedicine applications, USB cameras are used to capture high-resolution images or video footage for remote medical consultations, diagnostic purposes, or patient monitoring. They are employed in devices such as telemedicine carts or telepresence robots.

In the world of camera interfaces, USB (Universal Serial Bus) has emerged as one of the most popular and widely adopted options. Its widespread usage can be attributed to several key factors – such as easy integration, high bandwidth, and affordability – that make it a go-to choice for both professional and consumer cameras alike.

A USB camera module, in the embedded context, specifically refers to the camera component that consists of the sensor, baseboard, and lens mount. It may not include additional elements like an adapter board, lens, or ISP. The module serves as a building block that can be integrated into various embedded vision devices or applications, such as robots or industrial systems, with the ability to use the lens of your choice or an external ISP.
