ARRAY OF SCANNING SENSORS
First Claim
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.

Abstract
An array of image sensors is arranged to cover a field of view for an image capture system. Each sensor has a field of view segment which is adjacent to the field of view segment covered by another image sensor. The adjacent field of view (FOV) segments share an overlap area. Each image sensor comprises sets of light sensitive elements which capture image data using a scanning technique which proceeds in a sequence providing for image sensors sharing overlap areas to be exposed in the overlap area during the same time period. At least two of the image sensors capture image data in opposite directions of traversal for an overlap area. This sequencing provides closer spatial and temporal relationships between the data captured in the overlap area by the different image sensors. The closer spatial and temporal relationships reduce artifact effects at the stitching boundaries, and improve the performance of image processing techniques applied to improve image quality.
