Video: Image sensor uses dual speed streaming for security applications

22 July 2022

Sony Semiconductor Solutions Corp. (SSS) has introduced what it claims is the first complementary metal-oxide semiconductor (CMOS) image sensor for security cameras that simultaneously delivers both full-pixel output of the whole captured image and high-speed output of regions of interest.

The sensor uses dual speed streaming technology to output all the pixels in a captured image at a maximum rate of 40 frames per second. The sensor allows a single camera to provide comprehensive images of scenes but also supports high-speed recognition of specific objects at a high level of detail.

Using SSS’ STARVIS technology, the sensor has a high-sensitivity and a wide dynamic range but with about 30% less power consumption than conventional sensors. The STARVIS technology enables dynamic range of 78 dB, about 2.5 times that of conventional models.

Potential applications for the sensor beyond security cameras could be in drive recorders and webcams. In security cameras, the sensor can be used in security applications to capture a whole image of an intersection while recognizing people and cars moving through it, SSS said. Or it could be used to capture an overall image of a highway while capturing the details needed to identify the license plate numbers of cars traveling on it.
