Not so long ago, OmniVision, having launched the smallest medical camera on the market, became the holder of a world record officially registered in the Guinness Book of World Records. The record holder, the tiny OVM6948 CameraCubeChip device shown in the picture above next to a black pepper kernel, has a size of 0.575 by 0.575 millimeters, a resolution of 200 by 200 dots, and it has great potential to have a significant impact on the field of medical diagnostics, etc.
Currently, most of the subtle operations in the field of neurosurgery, cardiac surgery, gynecology, etc. are carried out almost blindly or using low-quality images that can provide fiber optic endoscopes. Only a few medical institutions can now afford the acquisition of technology that provides high image quality, and the tiny OmniVision module can be the solution to this problem.
“Our company’s technology offers a compact, high-quality solution, on the basis of which very affordable endoscopes, catheters and other devices will be created, the demand for which is growing literally every day,” says Aaron Chiang, head of OmniVision, “All this will reduce “risks of infection, and will reduce the time required for repair, pre-procedure testing and sterilization of reusable endoscopes.”
The OV6948 sensor, 0.65 by 0.65 in size and 1.158 mm long, is an OVM6948 camera mounted on a special tip. It also has a lighting device that guarantees high quality images, which is important when working in low light conditions. As a illuminator, a special LED is used that has a low operating temperature, which eliminates the heating of the sensitive elements of the camera matrix, reducing their sensitivity. All this provides the device with a viewing angle of 120 degrees and the ability to focus on objects located at a distance of 3 to 30 mm from the camera at a shooting speed of 30 frames per second.
The appearance of OmniVision cameras on the market will make it possible for medical institutions that previously could not afford such endoscopes due to funding problems to acquire compact endoscopes. In addition, patients who participated in the testing of prototypes noted “increased comfort and short rehabilitation time” after using this device compared to other similar devices, which is facilitated by the low power consumed by the camera (25 mW), eliminating undesirable side heating.
