Before the smartphones are launched, they go through several testing. It’s done to know whether the device stands true to its features. Of course, no brands want to face failure, so testing is a crucial phase of the product. Similarly, a CMOS image sensor test is conducted to know the quality of the image that the camera holds.
A Brief About CMOS Sensor
CMOS stands for Complementary Metal-Oxide-Semiconductor. Just like a computer chip, a CMOS sensor is an electronic chip that helps in digital processing. With the help of CMOS sensor-digital cameras, digital video cameras, and digital CCTV cameras can build images. From high-tech devices like telescopes to barcodes, use this chip. CMOS is more widely used than CCD (charge-coupled device); it’s one type of image sensor. Due to the barriers of CCD, which CMOS can do make it more in demand.
Like other semiconductor technologies, the automated test equipment features a range of tiny light-capturing cells that capture the photons at their several wavelengths as focused by a lens. Thus, translate them into electrons which are like a mini solar cell.
3 Reasons for CMOS Testing on Smartphones
➤ To Verify Biosensors
In hospitals, many diseases are detected under the microscope, like blood-borne diseases, tumor cell detection, and any bacterial infections. The objects which are challenging to see from naked eyes, a microscope comes in handy. The series of lenses in the microscope help to identify the disease. In 2007, it was discovered that mobile phones cameras capture objects from the eyepiece lens of a microscope. Afterward, with the help of CMOS, several imaging systems in smartphones are introduced to meet the demands of detection problems. Better to look for the 5G semiconductor testing before the launch to know the working of biosensors in your smartphones.
➤To Have a Better Quality of Smartphones’ Microscope
Do you know your smart-phones based microscope has an additional attachment that consists of a range of lenses and optical components? Due to these extra attachments, your smartphones serve as microscopes and produce images of analytes. Now as every brand tries hard to improve the quality of smartphone-based microscopes to stand out from competitors. How to check the quality? Again semiconductor testing is done to check if all the elements of the lens are working correctly or not.
➤ To Detect Image Functionalities of Smartphones
The increased number of cameras in smartphones has called attention to the need for high-resolution yet professional images. It’s vital to have CMOS testing to detect the functionalities of every camera. For instance, to check the low-light photography quality.
The Bottom Line
CMOS testing is crucial to know the quality & functionality of cellphones-based images. CMOS technology is gradually advancing to deliver high-end digital cameras. Moreover, the testing is affordable and gives the brands accurate testing results. I hope you now have a better understanding of CMOS sensor testing.
