Introduction to the SONY IMX390CPV CMOS Image Sensor 2021-09-13

SONY IMX390CPV is a 1/2.7” (RCCB color filter) stacked CMOS image sensor with a resolution of 2.12 MP suitable for use with Advanced Driver Assistance Systems (ADAS) and automotive cameras.

IMX390CPV features a LED flicker mitigation function to reduce flickering when shooting LED signs and traffic signals. It also has an HDR function capable of 120dB wide dynamic range shooting. LED flicker mitigation and HDR shooting were made possible through SONY’s proprietary pixel structure and exposure technique. High sensitivity means high-quality color images can be produced even when there is just 0.1 Lux of illumination (the equivalent of moonlight). IMX390CPV meets the requirements of AEC-Q100 Level 2 on reliability testing for automotive electronic components. SONY also introduced the ISO 26262 automotive functional safety standard during the development process to ensure a high standard of design quality for automotive products.
The RCCB CFA image sensor used in the IMX390 means direct transmission for 50% of the light source, while the red and blue light filters each account for 25%. RCCB offers sensitivity superior to RGGB in weak lighting. The captured image can be used for machine analysis or human observation.
Key IMX390CPV features:
1. Both LED flicker mitigation and HDR
SONY's proprietary pixel structure and exposure technique for IMX390CPV offers both LED flicker mitigation and HDR functionality. The sensor offers accurate recognition of LED signs and lights to the front and back of the vehicle. Imagery can be captured with a wide dynamic range as well to prevent the loss of details from over-exposure or excessive shadows, such as when entering or leaving a tunnel.
LED flicker mitigation function
LEDs are now widely used in traffic signs signals as well as car headlights, taillights and indicator lights. Car cameras must then capture these elements accurately. LEDs flicker at a very fast rate however. Even though these flickers are undetectable to the naked eye, they create a phenomenon referred to as LED flicker when captured on camera. Ordinary CMOS image sensors often experience flickering from LED light, which impacts the accurate recognition of signals and surrounding vehicles. IMX390CPV solves this problem by making the exposure time longer than the LED flicker frequency and minimizing the amount of flickering.
120dB HDR function
Car cameras must be capable of shooting clear videos with minimal noise or loss of details due to shadows and over-exposure in high contrast scenarios such as entering a tunnel during the day or driving in the city at night. IMX390CPV features SONY’s proprietary pixel structure and exposure method to deliver an HDR function capable of shooting with 120 dB of wide dynamic range with low noise.
2. High sensitivity of 3,325mV
IMX390CPV is equipped with circuitry that converts the electronic signal from the photo-diode into a voltage signal. Maximum sensitivity is therefore 150% higher than that of conventional image sensors in 2 MP car cameras. Therefore, the image sensor is capable of capturing high-quality color images when there is as little as 0.1 Lux of light, the equivalent of moonlight. Camera reliability for recognition of obstacles, people and objects is improved.
