Sony has developed a CCD (Charge Coupled Device) imaging sensor that can help automate the car to identify electronic road signs Sensor that are clearer when transitioning between dark tunnels and 'rudeness'.

The I MX390 sensor is equipped with an anti-flicker function, which means that the LED road sign image is clearer in the auto-driving 'eyes'. Since LED road signs are often used to indicate temporary changes in road conditions Fuel Rail Pressure Sensor or speed limits, it is important that autopilot vehicles recognize them.

  In the standard imaging sensor, due to the sensor scanning frequency and road signs display frequency differences, LED road signs look like a flash, or produce strobe effect. A similar problem sometimes occurs when shooting with a conventional camera at a TV.

  The IMX390 sensor also supports the HDR (High Dynamic Range) function, which means that it can see more details in high-contrast scenes, such as when the car is out of the tunnel in fine weather conditions. Under normal circumstances, the imaging sensor can 'see' the tunnel outside the scene, the tunnel Temperature Sensor will appear inside the 'dark', or can see the tunnel inside the scene, and the tunnel will appear outside the 'a white vast.'

  The HDR function helps to balance this situation so that the imaging sensor can 'see' the inside of the tunnel and 'see' the external scene of the tunnel, which is very important for autopilot vehicles and helps them in any Circumstances can 'see' the road ahead.

  Sony produced a video, the new sensor and the existing sensors were compared.
Prior to this, HDR and anti-flicker technology has emerged, but no one imaging sensor at the same time with these two technologies, so developers can only choose Pressure Sensor one or use two sensors. The Sony IMX390 sensor supports both technologies at the same time.

  Sony is the world leader in imaging sensors, and its imaging sensors are not only used in their own cameras and cameras, but also in the opponent's products.
