Atsugi, Japan — Sony Semiconductor Solutions Corporation (SSS) today announced the upcoming release of the IMX675, a 1/3-type CMOS image sensor for security cameras with approximately 5.12 megapixels*2 that simultaneously delivers both full-pixel output of the whole captured image and high-speed output of regions of interest.
The new sensor also employs unique STARVISTM 2 technology from SSS, which delivers high-sensitivity and a wide dynamic range, but with approximately 30% less power consumption than conventional models,*3 thanks to its proprietary stacked structure.
These technologies come together to deliver high-performance, high-quality image capture regardless of usage conditions or time of day, thereby contributing to a safer, more secure society.

The requirements for security cameras vary depending on where and how they are used. At the same time, keeping the number of cameras optimized at a minimum is necessary to keep system costs low.
Thanks to proprietary Dual Speed Streaming technology from SSS, the new sensor can simultaneously output the whole captured image and specific regions of interest at different frame rates, enabling capture of a comprehensive image of the scene while also accurately recognizing quick-moving objects, all with a single camera. This design helps reduce system costs. The new sensor can be used to capture, for example, the whole image of an intersection while recognizing people and cars moving through it, or to capture an overall image of a highway while also capturing the details needed to identify the license plate numbers of cars travelling on it.
Additionally, STARVIS 2, a technology which delivers high sensitivity and a wide dynamic range, but with approximately 30% less energy consumption than conventional models,*3 enables a dynamic range of 78 dB, approximately 2.5 times that of conventional models,*3 when used in a single exposure method. As a result, the new sensor product has potential applications beyond security cameras, for instance in drive recorders and webcams, both of which are seeing increasing demand in recent times.

Main Features
■Equipped with Dual Speed Streaming for simultaneous full-pixel output of captured images and high-speed output of specific regions of interest
This image sensor is the industry’s first*1 to employ Dual Speed Streaming technology to simultaneously output all pixels in a captured image at a maximum rate of 40 frames per second while also reading specific regions of interest at a high frame rate, a feat made possible by its original readout circuits. The location of the region of interest in the frame can be specified vertically, together with the corresponding frame rate. Depending on the purpose, users can choose to read only the necessary region at high speed to lessen the load on the camera system at a later stage by reducing the amount of data compared to the conventional method of reading all pixels.
Example of frame rate and region of interest vertical specification
-
Example 1
All pixels: 40 fps
Vertical spec (12.5%): 320 fps -
Example 2
All pixels: 10 fps
Vertical spec (25%): 80 fps
Data size drops 50% compared to example 1 -
Example 3
All pixels: 10 fps
Vertical spec (12.5%): 320 fps
Data size drops 37.5% compared to example 1
■Consumes 30% less power than conventional models*3
■Single exposure method with approximately 2.5 times wider dynamic range than conventional models*3
■Improved sensitivity in the near-infrared domain delivers high-quality images in dark locations
