ON Semi is seeing a marked increase in the number of image sensors deployed per car in ADAS functions. Its most recent introduction provides, among other features, flicker reduction. This is intended to eliminate, directly at the sensor, the strobing effect that can occur when the image sampling cycle 'beats' with the pulsed waveform driving LED tail-lights in other vehicles, or illuminated speed-limit signs.

The sensor also has a high dynamic range, substantially exceeding that of the human eye; and it is also the only sensor in its applications space, ON claims, to have ASIL B support. Using a 4-exposure capture cycle to achieve HDR (high dynamic range) the device can reach frame rates of up to 40 fps, and dynamic range of 120 dB ...
