A California-based company had made the smallest camera sensor that measures only 0.5mm but can capture 200 x 200 resolution video at 30 fps.
The smaller the things are, the more technologically profound they are. Imagine the size of the first memory card back in 1956 which had only 5MB storage and how enhanced the realm had become in years, that it’s possible now to fit thousands of 1TB SD cards at the size of world’s first 5MB memory card.
In that aspect, this smallest camera sensor ever designed is only the size of a grain of sand and has won Guinness World Record for being the smallest commercially available image sensor.
Smallest Camera Sensor
OmniVision Technologies based in California, an expert in medical camera sensors, made the OV6948 sensor that measures only 0.575 mm x 0.575mm x 0.232 mm in dimensions, but capable of capturing 200 x 200 resolution video at up to 30 frames per second (fps). It’s so tiny that seems to be a piece of dust.
Initially developed for smaller-outer-diameter medical endoscopes in the medical sector, the sensor also could be integrated in wide range of applications including IoT, industrial, wearables and forensic devices.
The sensor is fitted into OVM6948-RALA camera created by Omnivision, that can fit down to even the smallest veins of the human body assisting surgeons in surgical procedures.
It has a 1/36-inch optical format and offers low-light sensitivity of 1000 mV/ux-sec. The image sensor has a pixel size of 1.75 microns, and needs a single 3.3V power supply. It can withstand temperatures from -200C to 700C.
Due to sensor’s low power consumption, less heat is dissipated at the distal tip of endoscope during the procedure, which improves patient comfort and allows procedures for longer-duration.
“The sensor enables easy integration with a 4-pin interface and analogue data output, capable of data transmission of up to 4 meters with minimal signal noise,” the company explains.
The camera unit offers a 1200 wide-angle of view, offering a depth of field range from 3mm to 30mm. In contrast, here is the largest camera ever made in the world, capturing images at 3.2 billion-pixels quality.
