Abstract

According to an embodiment, a system can dynamically control integration time in a time-of-flight (ToF) device based on current operating conditions. A signal scaler processes calibration data and real-time measurements to determine expected signal and ambient rates. Parallel calculations determine required integration times-one based on achieving maximum ranging distance and another based on measurement precision requirements. The system selects the longer integration time and applies user-defined bounds to optimize power consumption while maintaining specified performance. By adapting integration time to ambient light conditions and target reflectance characteristics, the system enables shorter integration times in favorable conditions while automatically increasing duration when needed for distant or low-reflectance targets.
