The most important business for Sony today is that of the photo sensors, and seeing the explosion coming with the arrival of autonomous cars it was obvious that they had to search how to get into the business. This is how Sony is introducing its first sensor manufactured specifically for use in cars equipped with autonomous driving systems, the IMX390.
Sony says that it is also the first of its kind, since today autonomous cars they use cameras that are currently on the market, where none of them has been created to work in conditions that require a car that is constantly capturing images from the outside. Therefore, the Japanese want to be the first in this market and the first tests that have shown amazing results.
Sony IMX390: high sensitivity, HDR and technology anti-blink
Cameras are a very important element for autonomous cars, But today neither is optimized for this type of applications, they are not capable of handling complex lighting situations, making it difficult to read and detection of traffic signs as well as other vehicles and pedestrians.
Sony is presenting its new IMX390 sensor with 2.45 megapixels, where one of your keys is in its sensitivity of 120dB HDR, that allows you to have a better signal to noise ratio, which will have a greater dynamic range and thus handle different situations and changes in lighting in only a few seconds. It also has a of just 0.1 lux light sensitivity, which means that you will be able to perceive objects during the night under conditions of minimum illumination.
But one of the most important points of this sensor is that eliminates the so-called ‘ LED flicker’, It is that flicker that occurs on the screen or LED panels, which in situations spanning a car without a driver becomes very important. With this, the vehicle will be capable of detecting signs with clarity, which is have been updated in several regions of the world to screens and LED systems.
This sensor will be capable of working with these three elements at the same time, by combining these features depending on the scene. For example, the change of light when it enters or exits a tunnel, detect objects at night even though they are not illuminated, as well as identify the content of digital, such as traffic lights or displays signs, regardless of the location or the time of day.
Sony IMX390 will start its tests in this 2017, with a view to a production may large scale to make deliveries in March 2018. The best way to understand the benefits and capabilities of this sensor is through the following videos, where Sony is focused on the three key issues that we discussed.
