1. A method for combining image data, the method comprising: receiving a first sensor data set from a first sensor, the first sensor data set comprising a plurality of first subsets, each first subset comprising sensor data; receiving a second sensor data set from a second sensor, the second sensor data set comprising a plurality of second subsets, each second subset comprising sensor data; generating an image metric comprising a plurality of slots by repeating the following until a final slot of the image metric is reached: generating display data from a first subset for a slot of the image metric; and generating display data from a second subset for a next slot of the image metric; and displaying an image generated from the image metric.
