Simultaneous LED flicker suppression and high-quality HDR shooting
1/2.7-type effective pixel 2.45-megapixel CMOS image sensor for automotive cameras

Sony has announced the commercialization of a new 1/2.7-type 2.45-megapixel effective pixel IMX390CQV CMOS image sensor for automotive cameras. Sample shipments are scheduled to begin in May of this year.

The newly announced image sensor features flicker mitigation, which reduces screen flicker when photographing LED signs and traffic lights, and HDR capabilities, enabling 120dB*2 wide dynamic range shooting. It also boasts high sensitivity, enabling high-quality video capture even in low-light conditions as low as 0.1 lux, similar to moonlight.

Recently, LEDs have been widely used not only in traffic signals and signs, but also as light sources for automotive equipment such as headlights and brake lights. Furthermore, automotive cameras are required to capture high-quality images with a wide dynamic range, even in situations with significant contrast, such as when entering or exiting a tunnel during the day. This image sensor responds to these situations by simultaneously utilizing LED flicker suppression and HDR functions, thereby improving recognition accuracy in various real-world traffic environments encountered by drivers.

The IMX390CQV plans to meet AEC-Q100 Grade 2, the reliability testing standard for automotive electronic components, within this year. Sony has also adopted a development process that complies with the ISO26262 automotive functional safety standard, meeting ASIL C functional safety requirements.

A Sony official said, “The IMX390CQV meets these safety quality requirements and can be used in forward-sensing cameras for driver assistance systems (ADAS) and monitoring system cameras that replace rearview mirrors.”

Image sensor capable of capturing images quickly or slowly

When designing an image sensor, the most critical step is to fully understand how to use the device. The product equipped with the device must explain to customers how they should operate it. Customer requirements are endless, such as whether customers primarily want to use the device in high frame rate or low-light environments, or whether they want to optimize for low power consumption or low read noise. While it is natural that the finished product will be used in more than one way, if the use cases for the new product run counter to the direction desired in the design, complications can arise.

ON Semiconductor Unveils Imaging Solution for High-End Security Cameras

ON Semiconductor has introduced the AR0521 CMOS image sensor, an imaging product based on a 2.2 micrometer (μm) backside-illuminated (BSI) pixel technology platform specialized for security and surveillance applications. This latest imaging solution provides 8, 10, or 12-bit output and delivers excellent video performance at 5MP 6fps (frames per second) in 1440p mode to accommodate 16:9 video. The 2.2 μm BSI pixel provides a larger linear well while producing lower noise than smaller pixels, enabling superior low-light performance essential in security camera applications.

SalePoint Signs Multi-Year Partnership Agreement with AWS… Promoting Identity Security that Integrates Even AI Agents

Sailpoint has entered into a multi-year strategic partnership agreement with AWS and is moving forward with establishing an integrated governance system that manages both human and non-human identities together. The plan is to consistently manage access permissions in an environment where AI agents are increasing as work execution entities, while applying the principle of least privilege and automated policy enforcement. The two companies plan to jointly expand capabilities to manage the identities of various entities, including AI agents, within a single layer in the AWS environment. This collaboration is interpreted as a move to design security and governance together in corporate environments where AI adoption is expanding.

Databricks Unveils Open AI Security Monitoring 'Lakewatch'

Databricks entered the security market on March 24 by unveiling LakeWatch, an open-source agentic SIEM. The core functionality of this product is to integrate and analyze security, IT, and business data in a single environment to support AI-based threat detection and investigation. The company explained that it reduces the limitations of existing security operations centers, which have had to forgo some data due to high cost structures, and enables large-scale data analysis and automation based on open formats and ecosystems. LakeWatch is currently offered as a private preview, with Adobe and Dropbox mentioned as early customers. Databricks also announced an expanded partnership with Anthropic as well as the acquisition of Antimatter and SiftD.ai.
