1. A method for manufacturing a panoramic image sensor, comprising the steps of:
- providing a sensor body,disposing on the surface of the sensor body a plurality of imaging sensors, each having a field of view,presenting a pattern to the plurality of imaging sensors,allowing said sensors to capture an image of the pattern appearing in its respective field of view, andprocessing said captured images to identify overlapping regions within the fields of view of a plurality of sensors to thereby calibrate the plurality of image sensors to generate a panoramic image,wherein calibrating includes generating a lookup table having information of which sensor pixel of which sensor “
sees”
a portion of the pattern at a time.

Abstract
The systems and methods described herein include, among other things, a technique for calibrating the outputs of multiple sensors, such as CCD devices, that have overlapping fields of view and mapping the pixels of those outputs to the pixels of a display screen by means of a lookup table so that a user can see a selected field of view within the larger fields of view that are seen by the sensors.

12. Apparatus for calibrating a panoramic image sensor, comprising:
-
a sensor body, a plurality of imaging sensors, each having a plurality of pixels and being disposed on the surface of the sensor body and having respective fields of view, a pattern disposed within-the fields of view of at least two sensors for allowing said at least two sensors to capture an image of the pattern appearing in its respective field of view, and a calibration mechanism for processing said captured images to identify overlapping regions within the fields of view of a plurality of sensors and for generating a look up table correlating pixels in a panoramic image with pixels in said plurality of sensors, wherein the lookup table includes information of which sensor pixel of which sensor “
sees”
a portion of the pattern at a time. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method for manufacturing a panoramic image sensor, comprising the steps of:
-
providing a sensor body, disposing on the surface of the sensor body a plurality of imaging sensors, each having a field of view, presenting a pattern to the plurality of imaging sensors, wherein presenting a pattern includes tracing a pattern with a light source across a surface, allowing said sensors to capture an image of the pattern appearing in its respective field of view, and processing said captured images to identify overlapping regions within the fields of view of a plurality of sensors to thereby calibrate the plurality of image sensors to generate a panoramic image, wherein calibrating includes generating a lookup table with the information of which pixel of which sensor responds to the light source at a defined point on the pattern. - View Dependent Claims (25, 26, 27, 28, 29)
