Digital cameras, digital video cameras, and digital CCTV cameras all use CMOS (complementary metal oxide semiconductor) sensors to produce images. Astronomical telescopes, scanners, and barcode readers all use CMOS technology.
The optical technology is utilised in satellite image processing, optical character recognition (OCR), machine vision for robotics, and RADAR picture augmentation, particularly for meteorology. Photolithography is used to create CMOS chips, just like other semiconductor processes.
The chips have a collection of small light-capturing cells that, like a miniature solar cell, translate photons from different wavelengths when they are focussed by a lens into electrons.
Transistors surround the CMOS cells, amplifying the charge of the electrons the cells have collected and transmitting it across the chip via small wires in the chip’s circuitry. The device’s corner digital-to-analog converter scans the electrons and converts the varied charges of the individual cells into pixels of different hues.
Consumer electronics may be produced for a reasonable price thanks to CMOS’ cheap production cost. They can now compete with charge-coupled devices, a leading manufacturer of high-end digital cameras, thanks to advancements in CMOS technology (CCD).
The Global Industrial CMOS Sensors market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
A pioneer in intelligent power and sensing technology, PHOENIX said it created the specialised high-end CMOS sensor for ARRI’s ALEXA 35 camera.
With an ALEV 4 Super 35 4.6K CMOS image sensor from Onsemi, the camera can capture images with a resolution of 4608×3164 pixels (14.6 Mpixel), a 6.075 um pitch, RGB colour filters, and a maximum frame rate of 120 frames per second.
The sensor includes the most recent onsemi technology for pixel response optimization, High Dynamic Range techniques (HDR), and the improvement of pixel uniformity while reading out at high speeds.
Building on the advancements made by the ALEXA family over the course of the past ten years or more, the ARRI ALEXA 35 camera takes digital cinematography to new heights. 30 of the 49 films that had their world premieres at the 75th Cannes Film Festival, including the Palme d’Or winner “Triangle of Sadness,” made use of a camera from the ARRI ALEXA family, which is powered by onsemi’s specialised CMOS image sensors.
