Patent ID: 8854481

Claim:
An image stabilization device, comprising: a sensor having an array of pixels, wherein the sensor is configured to: identify a particular portion of a moving object by: counting, by each pixel, a number of electrons collected in its potential well; comparing, by each pixel, the number of electrons collected in its potential well to an electron threshold; determining, by any pixels whose number of electrons collected in their respective potential well meets or exceeds the electron threshold, a Gaussian curvature at their respective location; comparing, by the pixels whose number of electrons collected in their respective potential well meets or exceeds the electron threshold, an absolute value of their respective determined Gaussian curvature to a curvature threshold; and identifying, by a number of pixels whose number of electrons collected in their respective potential well meets or exceeds the electron threshold and whose absolute value of their respective determined Gaussian curvature meets or exceeds the curvature threshold, the particular portion of the moving object; track the moving object using the number of the pixels, wherein the number of the pixels track only the particular portion of the moving object; and form an image of the moving object using the number of the pixels and their neighboring pixels that were not used to track the moving object.
