Sony Semiconductor Solutions Corporation (SSS) today announced the upcoming release of the IMX925 stacked CMOS image sensor, featuring a back-illuminated pixel structure and global shutter technology. Designed for industrial imaging, the new sensor offers 394 fps high-speed processing and a 24.55 effective megapixel count.
Pregius S global shutter technology
The IMX925 integrates Pregius S global shutter technology, providing a compact design with minimal noise and superior image quality. It also features a new circuit structure that optimizes pixel reading and sensor drive in the A/D converter.
This results in processing speeds that are approximately four times faster and twice as energy-efficient compared to previous models, such as SSS’s IMX530.
Along with the IMX925, SSS will launch additional models with varying sensor sizes and frame rates. These will enhance recognition and inspection tasks in industrial equipment, improving productivity in industries where fast, high-quality imaging is increasingly required.
Models
- IMX925 and IMX935: 1.2-type (19.3 mm diagonal), 24.55 effective megapixels
- IMX926 and IMX936: 1/1.1-type (14.0 mm diagonal), 12.41 effective megapixels
As factory automation continues to grow, there is a rising demand for machine vision cameras capable of fast, high-quality imaging. The IMX925 sensor, with its global shutter and back-illuminated pixel structure, delivers exceptional pixel characteristics, high sensitivity, and superior saturation capacity. These sensors are particularly useful for recognizing and inspecting electronic components.
The IMX925 is compact enough to be C-mount compatible, making it ideal for machine vision cameras. It offers higher frame rates, reducing inspection times and energy usage. The sensor is also expected to support advanced inspection processes, such as 3D inspections, which involve multiple image data.
Specifications
Key Features
- Optimized circuit structure: The new circuit design enables high-speed imaging and power efficiency. The IMX925 provides a 394 fps frame rate, about four times faster than previous products, with more than double the power efficiency.
- Global shutter with proprietary pixel structure: The Pregius S global shutter ensures high-definition, distortion-free imaging of fast-moving objects. The back-illuminated pixel structure provides high sensitivity and saturation with 2.74 µm pixels.
- Higher data transmission: The sensors use SSS’s SLVS-EC interface, supporting up to 12.5 Gbps per lane. This enhances camera precision and speed with fewer data lanes and expanded FPGA options.
Availability
The IMX925, IMX935, IMX926, and IMX936 image sensors are expected to begin sample shipments in May 2025.
