Embedded infrared image super frame processing method based on fixed integral time

The invention provides an embedded infrared image super frame processing method based on fixed integral time. The embedded infrared image super frame processing method comprises the following steps: carrying out local motion estimation on continuous two frames of images output by an infrared focal plane detector by a super frame imaging and processing circuit according to external control signals, and judging a scene changing rate; repeatedly reading primary light current signals generated by the detector by virtue of a reading circuit in the single frame forming time by an infrared imaging system; selecting a corresponding sub-frame accumulation method according to the scene changing rate, carrying out non-uniform correction compensation and the sub-frame accumulation on sub-frames by using the super frame imaging and processing circuit, generating novel image frame, mapping the novel image frames and processing the rest of images, and outputting according to image outputting frame frequency and format of the conventional infrared imaging system. The embedded infrared image super frame processing method has the advantages of the conventional super-frame algorithm; the super frames are processed by an embedded platform; the application of a complex special device is omitted; a proper sub-frame accumulating method is selected by taking the scene image changing rate into account.
