Sony Develops Back-Illuminated Time-of-Flight Image Sensor With the Industry's Smallest Pixel Pitch

Sony Corporation today announced it has developed a back-illuminated time-of-flight ("ToF") image sensor with a 10µm pixel pitch, the industry's smallest...

This image sensor is equipped with an LED flicker mitigation function that reduces flickering when shooting LED signs and traffic signals, as well as an HDR function capable of 120dB wide dynamic range shooting.

The IMX390CQV is the first in the industry that can simultaneously mitigate LED flicker and shoot in HDR, a capability made possible by Sony's original pixel structure and exposure method. It also offers high-sensitivity performance capable of producing high-quality color images even in light conditions as low as 0.1 lux, which is equivalent to moonlight.

This image sensor simultaneously uses both the LED flicker mitigation and HDR functions to deal with these types of situations, providing more precise recognition in the diverse real-world traffic environments that drivers encounter.

The IMX390CQV is planned to meet the requirements of the AEC-Q100 Grade 2 automotive electronic component reliability tests this fiscal year. Moreover, with this new product, Sony also introduced a development process that complies with ISO26262 automobile functional safety standards, aiming to achieve a high level of design quality for an automotive product.

The new sensor also meets the functional safety requirement level ASIL C. By meeting these standards and quality requirements for automobile components, the product is ready for use in forward-sensing cameras for Advanced Driver Assistance System (ADAS) and cameras for Camera Monitoring System (CMS) that show persons and obstacles on an in-car monitor with clear visibility, an application expected to grow as a substitute for conventional rearview mirrors.
