Sony sensor quadruples performance for industrial imaging
November 20, 2024
Sony Semiconductor has launched a 25Mpixel image sensor with a global shutter at 394 frame/s for high speed industrial automation.
The IMX925 stacked CMOS image sensor has a back-illuminated pixel structure with a high, 24.55-effective-megapixel count and is optimized for industrial equipment imaging.
A circuit structure optimizes pixel reading and sensor drive in the A/D converter, making processing approximately four times faster and twice as energy efficient as previous sensors while improved signal processing boosts the frame rate.
Along with the IMX925, Sony will also release three models in May 2025 with different sensor sizes and frame rates for recognition and inspection tasks in industrial equipment.
The IMX925 sensor is compact enough to be C mount compatible, the most common mounting standard for machine vision cameras. The increased image capture per unit of time reduces measurement and inspection process times and helping to save energy. The product is also expected to be useful in advanced inspection processes such as 3D inspections which employ multiple image data.
The new products are equipped with Sony’s proprietary Pregius S global shutter technology. The back-illuminated pixels and stacked structure enable high sensitivity and saturation capacity on very small, 2.74 µm pixels. This structure delivers 24.55 effective megapixels on the IMX925 in a C-mount-compatible 1.2-type size, delivering a high pixel count in a compact package.
This design also ensures that the sensors can capture fast-moving objects free of distortion, which in turn makes the products highly useful in compact, high-definition machine vision cameras that can be easily installed on equipment and manufacturing lines.
The sensors use Sony’s embedded clock SLVS-EC high-speed interface, which supports up to 12.5 Gbps/lane. With high-resolution image data transmitted on fewer data lanes than in the past, FPGA options are expanded, supporting the development of high-precision, high-speed cameras.
