Original Abstract Submitted
this disclosure describes adaptive synchronization techniques for mitigating the impact of light flickering on images captured with active pixel sensor (aps) image sensors. in particular, these techniques apply to applications wherein the precise time at which an image is captured is not a critical parameter, such as machine vision (mv) applications. the techniques consist of repeating image captures until an image quality criterion is met, before transmitting the image to another system or processor for post-processing. the time between successive image captures may depend on the complexity of the on-sensor auto-exposure algorithm. the image quality criterion could change dynamically, e.g., based on parameters set by a host processing unit of the image capture system. one exemplary image quality criterion could be to determine that an average illuminance value for a region of interest (roi) with a given image is within a threshold amount of a target average roi illuminance value.
