Abstract
Techniques, devices, and systems disclosed herein include detecting a vertical synchronization (VSYNC) signal cycle, determining a high frequency trigger pulse based on detecting an illumination component's pulse width modulation (PWM) signal, the high frequency trigger pulse corresponding to the illumination component's deactivation times, receiving a delay time period and activating a first sensor, at a first time, within the VSYNC signal cycle, the first time determined based on the high frequency trigger pulse and the delay time period. The first sensor may sense a first sensor reading and may be deactivated after being activated. A display setting may be adjusted based at least on the first sensor reading and the illumination component may be activated after the first sensor is deactivated.
