Image sensor comprising an imaging module installed in a body module and a lens module

An image sensor comprising:

• a main body module;
• and
• a lens module and an imaging module mounted on the main body module,
• wherein the imaging module comprises:
• an imaging element, and
• a first hardware controller, configured to set an information for distortion aberration correction and perform distortion aberration correction on an image data output by the imaging element by using the set information for distortion aberration correction, and
• the main body module comprises a second hardware controller configured to:
• acquire an imaging module form information indicating a form of the imaging module from the mounted imaging module and acquire a lens module form information indicating a form of the lens module from the mounted lens module,
• acquire a size information indicating a number of pixels and/or a pixel size of the imaging element within the mounted imaging module and a distortion aberration characteristic information indicating distortion aberration characteristics of an optical system within the mounted lens module from a predetermined device by using the imaging module form information and the lens module form information, and
• set the size information and the distortion aberration characteristic information of the imaging module as the information for distortion aberration correction.
