Abstract
An active pixel imaging system and method to generate an differential output signal consisting of the differences in a viewed image between adjacent detected flames. A buffered electrical charge storage capacity of the active pixel sensor is utilized to provide a system with reduced complexity and hardware requirements. In the imaging system, when a particular active pixel sensor is activated it generates a voltage signal corresponding to a previous frame's detect light intensity before the pixel is reset to generate a voltage signal corresponding to a present frame's detected light intensity. A differential output circuit is used to generate a differential output signal based on these two generated voltage signals.
