Continued from Sony Demoes Automotive Image Sensors at CES (1)

Second, Sony demonstrated that its wide-dynamic-range image sensor can take images both in a bright place with a brightness of about 40,000lx and in a dark place like a tunnel. Though the company did not disclose a specific dynamic range, it said that the dynamic range is wider than that of existing products (120dB).

Third, Sony had two kinds of demonstrations by using an image sensor whose pixel count was increased. One is to take horizontally-wide images by combining the sensor with a wide-angle lens with an FOV of 120°. The other is to take clear images of a distant sign by combining the sensor with a narrow FOV.

In the second demonstration, Sony showed that it is possible to take a clear image of a 1:18 scale model of a sign located 10m away (equivalent to the full-scale sign located 180m away). The pixel count of the sensor is larger than that of the 7.42-Mpixel product that the company announced in October 2017 (See related article).

"We placed the sign 10m away in consideration of the size of the booth, but it is possible to take images of it with no problem even if we put it farther away," the company said.

Also, in its booth, Sony exhibited a concept model of "Safety Cocoon," which uses about 10 image sensors and checks the 360-degree surrounding environment to ensure safety at the time of automatic driving.

Furthermore, Sony showed video of the automotive application of the ToF (Time of Flight) sensor that it announced in December 2017. For example, the company expects that the sensor will be set up in the interior of a vehicle for facial and gesture recognition.
