Abstract
This application describes method and apparatus for LED Flickering Management (LFM) using spatially multiplexed image sensors. An example method includes configuring the sensor with diverse exposure settings to capture images of a scene with an LED light source. For each pixel position, multiple intensity values are collected across these images. An estimated linear regression model, incorporating an estimated Quantum Efficiency (QE) factor, is constructed using these values. The pixel intensities are then adjusted based on this estimated QE factor, aligning them with the regression model. This process results in modified images of the scene, effectively managing LED flickering for accurate image capture.
