Sony Releases CMOS Image Sensor for Automotive Cameras with 5.4 Effective Megapixels,
Sony has improved the saturation illuminance through a proprietary pixel structure and exposure method. When using the HDR imaging and LED flicker*3 mitigation functions at the same time,
this offers a wide 120dB*4 dynamic range, about three times higher than that of the previous product.
This means highlight oversaturation can be mitigated, even in situations where 100,000 lux sunlight is directly reflecting off a light-colored car in the front, and the like,
thereby capturing the subject more accurately even under road conditions where there is a dramatic lighting contrast such as when entering and exiting a tunnel.
