Abstract
Systems and methods for camera sensor system self-calibration are disclosed. In an exemplary embodiment, a method may include exposing a camera sensor system to a known output from a camera display. The method may also include determining a calibration value by comparing image signals from the camera sensor system to expected values based on the known output from the camera display. The method may also include storing a calibration value in memory for retrieval during camera use.
Claims20
A method for camera sensor system self-calibration, comprising:
- exposing a camera sensor system to a known output from a camera display;
- determining a calibration value by comparing image signals from the camera sensor system to expected values based on the known output from the camera display;
- and
- storing a calibration value in memory for retrieval during camera use.

A camera system comprising:
- a camera display generating a known output;
- a self-calibrating camera sensor system attached to the camera display, the self-calibrating camera sensor system generating image signals corresponding to the known output when positioned adjacent the camera display;
- processing logic executing to compare the image signals generated by the self-calibrating camera sensor system to the known output from the camera display, the processing logic determining a calibration value for the self-calibrating camera sensor system based on the comparison;
- and
- a sensor control for applying the calibration value to the self-calibrating camera sensor system during use.
