The USB camera module is a general-purpose camera control board designed for both PCs and embedded systems like the ARM, Raspberry Pi, Odroid, and similar hardware. It supports almost all parallel interface image sensors and many MIPI camera sensors, including both global and rolling shutter sensors. The USB cameras adopt the standards of the USB interface, so they are easily expandable and adapted. What’s more, they could be made driver-free by following the USB device standards.
The UVC is one of the USB device classes. The drivers for UVC cameras to work have already been preinstalled in the operating system. Those driver-free USB cameras are UVC cameras. Computer and other mobile devices are connected directly through the USB interface — simply plug and play. These UVC compliant camera modules are compatible with Windows and Linux software and do not require drivers. The USB camera module integrates the camera unit and the video capture unit, and then connects to the host system through the USB interface. The camera unit combining the camera lens to the image sensor depends on different image requirements like view angle, resolution, sensor features, etc. The video capture unit usually considers the image processing application: the filter which wavelength band we need, compatible DSP or microcontroller, sensor commands support, frame rate, etc. IADIY offers several UVC board cameras as an implement for our current embedded MIPI camera modules. These cameras have more case-specific features like Wide Dynamic Range (WDR), low light enhancement, and also different view angle camera lens optional.

An electronic shutter electronically turns the image sensor on and off to control exposure. The sensor starts detecting light when activated and stops detecting light when deactivated.
Rolling shutter cameras capture the scene line by line, from top to bottom, causing a time difference between top and bottom parts. Motion or camera movement results in the distortion known as the rolling shutter effect. On the other hand, a global shutter camera is designed to capture an image by simultaneously exposing all the pixels in its image sensor to light for a brief period of time. Unlike a rolling shutter camera, which scans the image sensor row by row, a global shutter camera captures the entire image instantaneously.
Rolling shutter distortion is an effect that can occur while using rolling shutter cameras to capture fast-moving subjects. It is caused by the delay between the beginning and the end of the sensor readout. This can result in vertical or horizontal lines appearing bent or slanted, giving the image a distorted appearance. More global shutter camera module information is available at camera sensor module introduction or custom camera module requirements flow.
Since the rolling shutter captures different parts of the image at slightly different times, it can create motion blurriness. When there is an object moving at a very high speed, it may appear distorted or elongated due to the time difference in capturing different parts of the target. This is particularly noticeable in sports photography or when capturing moving vehicles. A faster shutter speed reduces the sensor's exposure time to light, helping to minimize motion blur. However, even at high shutter speeds, rolling shutter distortion can still occur if the subject is moving extremely fast. In such cases, the most effective solution is to use a camera module equipped with a global shutter. For capturing high-speed motion accurately, we recommend trying our global shutter camera module.
As our manufacturing facilities provide optics and camera modules design service and manufacturing of electro-optical subsystem, optical lens, camera module, image processing and laser sensing. We dispose of an unsurpassed design and development capacity, comprising an in-house optics & photonics division, an hardware division and an software integration division making us the ideal choice for clients who wish to outsource crucial designs and manufacturing to a highly qualified and trusted partner. As the camera module structure, we divide into 3 main sections:
Image sensor is the key part of camera sensor module. It decides the major parameters and features including image pixels and resolution, frame rate, S/N ratio, dynamic range, sensitivity, functions and control command support, etc.
Main characteristics of camera lens: diameter size, image circle(image size for sensor), focal length, FOV(field view angle), pixel resolution, F-number, distortion, environment reliability requirements, and the additional optical filter request.
The sensor driver is a necessary pare for driving the sensor to work and connect to the processor. It's a software program can be controlled by the processor need to consider whether the processor driver can support, the data interface and format of the processor need. Because there are too many kinds of processor and the driver programed for each different one. You'd better choose the image sensor there's the driver version for your processor. MIPI Alliance is an organization that develops interface specifications, the MIPI Camera Serial Interface was widely used in mobile industries. As this camera interface was high-performance, cost-effective. It was quickly expanded beyond the mobile industry. The MIPI camera module is separated with the DSP. It needs to program the firmware of DSP and using the grabber board to test in development and production.

Thermal module is the core of a thermal camera, consisting of infrared detector and processing circuits. IADIY thermal camera modules adopts high-performance infrared detectors for ultra-clear thermal imaging and sccurate temperature measurement. As our manufacturing facilities provide optics and thermal camera modules design service and manufacturing of photoelectronic, optical lens, sensor module, and image processing. We dispose of an unsurpassed design and development capacity, comprising an in-house optics & photonics division, an hardware division and an software integration division making us the ideal choice for clients who wish to outsource crucial designs and manufacturing to a highly qualified and trusted partner.
The higher an object's temperature, the more infrared radiation is emitted. Thermal camera can detect this radiation in a way similar to the way an ordinary camera detects visible light. It even works in total darkness because ambient light level does not matter. This makes it useful for rescue operations in smoke-filled buildings and underground. Thermal camera module is the core of the thermal camera, which detects infrared radiation and convert it into electric signals for thermal image processing. It can be applied in various fields such as outdoor night vision, temperature measurement, fire prevention, health and medical care, and autopilot. As the thermal camera module structure, we divide into 3 main sections:
Thermal Infrared sensor is the key part of thermal camera module. There are two types of thermal modules. Uncooled LWIR thermal camera sensor module can provide crisp and clear thermal images under normal temperature conditions. Cooled MWIR Camera Module adopts a variety of image processing algorithms, which is suitable for extreme conditions and applications. It is designed can be easily integrated into infrared systems that require advanced cooling and high-resolution thermal imaging solutions. It can detect small targets at extreme ranges making them highly suited for long range applications in challenging weather conditions.
Thermal imaging lenses, also known as thermal infrared lenses are made from materials like germanium and zinc selenide, and are transparent to infrared wavelengths. When choosing a thermal imaging lens, you can consider requirements like: spectral range, thermal sensitivity, resolution, range, and FOV(field of view), etc...
The image processing chip and circuit is a necessary part for driving the thermal sensor. With the help of AI image enhancement technology, AI SOC embedded ISP and processor can support enhanced resolution and improved image quality, while improving object recognition response speed. Through the application of AI ISP, the video surveillance industry can achieve improvements in video image quality, optimization of intelligent analytics, and enhanced security protection.
