Sony’s IMX928 Global Shutter Sensor: A Leap Forward in Industrial and Machine Vision

Sony Semiconductor Solutions has begun shipping samples of the IMX928, a 68.16-megapixel global shutter image sensor designed to deliver high resolution and speed for demanding imaging applications. This marks a significant step in the product lifecycle, moving the sensor from development to evaluation and potential integration into future camera systems.

Key Features and Specifications

The IMX928 distinguishes itself through its large format and unique geometry. Classified as a Type 2.0 optical format sensor with a diagonal of approximately 31.9 millimeters, it’s substantially larger than typical machine vision sensors and approaches the size of full-frame photographic sensors. The square sensor measures roughly 22.5 by 22.5 millimeters, offering a flexible imaging area of approximately 8256 by 8256 pixels.

A key advantage of the IMX928 is its global shutter architecture. Unlike rolling shutter sensors, a global shutter exposes every pixel simultaneously, eliminating distortion when capturing prompt-moving objects. This is particularly crucial in industrial and machine vision applications where accurate capture of dynamic scenes is essential.

Performance and Speed

Despite its high resolution, the IMX928 achieves impressive readout speeds. Sony specifies a frame rate of approximately 90 frames per second at 12-bit output. This performance places it among the fastest large-format global shutter sensors currently available. The sensor’s ability to capture 12-bit images at this speed is achieved through optimizations in sensor drive, pixel reading, and the analog-to-digital (A/D) converter.

Part of a Growing Family

The IMX928 is part of Sony’s Pregius S family of global shutter sensors and builds upon the foundation laid by the 105-megapixel IMX927, released in September. The family too includes the IMX929, which prioritizes even higher frame rates, reaching 136 frames per second. This expansion demonstrates Sony’s commitment to advancing global shutter technology across various sensor formats and performance levels.

Applications and Market Focus

While primarily targeted at industrial and machine vision markets, the IMX928’s capabilities have implications for other areas. The sensor’s square format and flexible output options are particularly well-suited for applications requiring adaptable framing and multi-aspect delivery. The availability of sample shipments signifies that manufacturers can now begin integrating the IMX928 into prototype systems, paving the way for commercial products in the near future.
