Field: Audio-visual technology (Electrical engineering)
Classification: CPC A  G  H | IPC G  H

Claim 0:
1. An image sensor comprising:
a first radiation detector and a second radiation detector, each of which comprising a planar surface configured to receive radiation from a radiation source; and
a calibration pattern;
wherein the planar surfaces of the first radiation detector and the second radiation detector are not coplanar;
wherein the image sensor is configured to capture an image of a first portion of the calibration pattern and an image of a second portion of the calibration pattern, respectively using the first radiation detector and the second radiation detector;
wherein the image sensor is configured to determine a first transformation for the first radiation detector based on the image of the first portion of the calibration pattern and to determine a second transformation for the second radiation detector based on the image of the second portion of the calibration pattern;
wherein the image sensor is configured to capture an image of a first portion of a scene and an image of a second portion of the scene, respectively using the first radiation detector and the second radiation detector, to determine a first projection of the image of the first portion of the scene onto an image plane using the first transformation and to determine a second projection of the image of the second portion of the scene onto the image plane using the second transformation, and to form an image of the scene by stitching the first projections and the second projection.
