1. In a system of image sensors using a scanning technique to capture image data, a method of image processing image data in an overlap area comprising: capturing image data in a first direction of traversal for a first overlap area of a first field of view (FOV) segment in an overlap time period, the first overlap area being shared with a second adjacent FOV segment; and capturing image data in a second direction of traversal opposite to the first direction of traversal for the first overlap area of the second FOV segment in the same overlap time period.
