Claim:
1. A method of providing merged video content from two independent video sources via a processor located onboard an aircraft, comprising: receiving an enhanced frame associated with an enhanced vision video from an enhanced vision system; receiving a synthetic frame associated with a synthetic vision video from a synthetic vision system; analyzing the enhanced frame to detect objects according to a first algorithm by receiving a set of pixels from the enhanced frame and determining whether the set of pixels correspond to a detected default frame segment of the synthetic frame, wherein the first algorithm is an object detection algorithm based upon an intensity difference threshold, the intensity difference threshold based on a minimum and a maximum intensity detected in the enhanced frame, and wherein analyzing the enhanced frame comprises altering the object detection algorithm to prevent the object detection algorithm from analyzing the set of pixels in response to the set of pixels corresponding with the detected default frame segment of the synthetic frame, and wherein the object detection algorithm is further altered to lower the intensity difference threshold to increase the presence of detected objects in the enhanced frame after the aircraft has taken off and before the aircraft has landed in response to the aircraft entering a landing phase of flight; analyzing the synthetic frame to provide the at least one detected default frame segment; selecting the detected objects from the enhanced frame and an enhanced frame segment from the enhanced frame corresponding to the detected default frame segment from the synthetic frame; providing the selected detected objects and the enhanced frame segment to a merged frame, wherein the merged frame comprises the detected objects, the enhanced frame segment, and the synthetic frame without the detected default segment; displaying the merged frame on a display, wherein the merged frame is provided as a single image representing the detected objects, the enhanced frame segment and the synthetic frame without the detected default segment correlated in the single image by position.
