Abstract: A sensor array module with wide angle for creating a composite image includes a first image sensor, a second image sensor, a storage unit and a processor. The first image sensor is for capturing a first image. The second image sensor is for capturing a second image and has a relative spatial relationship with respective to the first image sensor. The storage unit stores at least one transformation matrix obtained according to the relative spatial relationship between the first and the second image sensors. The processor combines the first image and the second image by using the transformation matrix to create the composite image. The present invention also provides an image calibration method, an operation method and an application for a sensor array module with wide angle.
