In November 2025, Samsung Electronics announced the official start of mass production for its ISOCELL Auto 4AC image sensor—the company’s first product optimized specifically for automotive scenarios. Focused on Surround View Monitoring (SVM) and Rear View Camera (RVC) applications, the sensor delivers all-weather clear vision for intelligent driving, leveraging its proprietary Corner Pixel™ technology and stringent automotive-grade certifications.
The sensor’s core innovation lies in its Corner Pixel™ structure: each pixel area integrates two photodiodes (3.0μm and 1.0μm), tailored respectively for low-light imaging and bright-light detail capture. This design enables a 120dB High Dynamic Range (HDR), allowing seamless handling of high-contrast scenarios such as tunnel entry/exit and backlit driving while minimizing motion blur. To address flicker from LED traffic lights and vehicle headlights, the sensor suppresses LED flicker above 90Hz by extending the exposure time of small pixels, providing accurate image data for autonomous driving systems.
Certified to AEC-Q100 Grade 2 standards, the ISOCELL Auto 4AC operates stably across an extreme temperature range of -40℃ to 125℃, covering diverse climatic conditions worldwide. It adopts a 1/3.7-inch optical format, integrating 1.2 million pixels (1280×960) with an Image Signal Processor (ISP). This integration enables direct output of high-definition images and simplifies the integration process of in-vehicle systems.
Duckhyun Chang, an executive from Samsung’s Sensor Division, noted that the ISOCELL Auto 4AC marks the starting point of the company’s automotive product lineup, with future expansion planned into fields like cockpit monitoring and high-level autonomous driving. Currently, the number of cameras per intelligent vehicle globally has increased to 6–8 units. The mass production of this sensor is expected to further strengthen Samsung’s competitiveness in the in-vehicle imaging sector and provide core visual component support for automakers including Tesla and NIO.
