Sony launches large format CMOS image sensor with global shutter function and industry’s highest effective pixel count of 127.68 megapixels

TOKYO, March 10, 2021 /PRNewswire/ — Sony Corporation today announced the upcoming release of a 56.73mm diagonal large format CMOS image sensor “IMX661” for industrial equipment with a global shutter function and the sensor the highest in the industry*1 effective pixel count of 127.68 megapixels.*2

This product features an increased pixel count that results in an optical size nearly 10 times larger than the common 1.1-type image sensor corresponding to the C-mount*3 for industrial equipment. It also features Sony’s original global shutter pixel technology “Pregius“, which enables image capture without motion distortion. In addition, Sony’s original device configuration and the interface technology used enable high-speed image playback at a data rate close to four times faster*4 than conventional products.

Sony expects the new sensor, when used in industrial equipment cameras for a wide variety of applications, will help solve a variety of complex challenges, thereby contributing to the development of the industry.

*1: Among CMOS image sensors equipped with a global shutter. According to Sony’s research (as of the date of the announcement of the March 9, 2021).
*2: Based on the effective pixel specification method of the image sensor.
*3: The junction mechanism between the lens and the camera body.
*4: Compared to Sony’s “IMX253” 1.1 type, 12.37 effective megapixel CMOS image sensor equipped with global shutter function.

The needs for automation, labor saving and other benefits of digital transformation have been steadily growing in recent years in various fields of industrial equipment. This has accelerated the adoption of cameras for a wide variety of applications, driving demand for CMOS image sensors with higher imaging performance.

The new product combines Sony’s Pregius technology with large 3.6-type optical size (56.73mm diagonal), delivering increased pixel count and motion-distortion-free imaging. The device’s original configuration, which uses a chip-on-wafer process, along with Sony’s original interface technology, achieves high-speed playback nearly four times faster than conventional products*4 in full pixel playback mode. This design provides highly efficient imaging that captures a wide viewing angle without motion distortion in a single imaging operation. It also improves recognition accuracy through high-resolution imaging and provides a high level of processing performance. It can contribute to solutions for a variety of industrial equipment applications, for example, inspection processes for the production of electronic displays and substrates, large-scale monitoring and aerial photography, where its improved accuracy and its faster reading will help meet the need for a high level of productivity.

main Features

  • Industry’s highest effective pixel count at 127.68 megapixels
  • High-speed image playback
    Generally, increased pixel count means increased signal processing volume, which leads to issues such as lower frame rate and longer playback times. In order to realize high-speed playback, it is necessary to improve the processing functionality of the AD converter which converts the analog signal output of the pixel into digital signals, and at the same time, to increase the speed of the interface of exit.
    This product features Sony’s original device configuration using a chip-on-wafer process where chips with certain functions are stacked on the pixel wafer, allowing for optimal positioning of the AD converter. This design improves the processing functionality of the AD converter without increasing the size.
    The new sensor also uses the high-speed Scalable Low Voltage Signaling with Embedded Clock (SLVS-EC™)*7 interface standard developed by Sony to speed up the output interface. These two original technologies enable 127.68 megapixels, 10 bits, 21.8 fps, a high-speed output data rate nearly four times faster than conventional models*4. The dramatic increase in multipixel and readout speed greatly contributes to improved productivity in industrial applications.
  • *7: A data transfer method that uses an embedded clock signal. This eliminates the need to adjust the tilt between lanes and reduces the amount of cabling required, making the board design simpler and suitable for higher speeds.

    • Equipped with the signal processing capabilities needed for a variety of industrial applications
