Google patents video tech that fixes blur using motion sensors

This patent describes a method for stabilizing video and removing blur in real time by using data from motion sensors instead of analyzing the image pixels directly. The system calculates how much the camera moved to create a correction filter, then refines this filter with a mathematical tool to sharpen the image while controlling noise.

Why it mattersThis approach could make video recording on phones and cameras smoother and clearer without slowing down the device, as it relies on cheaper sensor data rather than heavy image processing.

In the filing’s own words

Systems and methods for real-time image deblur and stabilization can utilize sensor data for estimating motion blur without the high computational cost of image analysis techniques. The estimated motion blur can then be utilized to generate a motion blur kernel for image correction. The systems and methods can further refine the correction by processing the motion blur kernel with a polynomial filter to generate a sharpening kernel. The systems and methods can provide for real-time correction even with minimal to no stabilization masking.

What exactly they claim (claim 1)

1. A computer-implemented method for improved deblurring of an image, the method comprising: generating, by a computing system comprising one or more processors and one or more sensors, sensor data, wherein the sensor data is descriptive of motion occurring during an exposure time of the image; determining, by the computing system, an estimated motion blur for the image based on the sensor data; determining, by the computing system, masking strength for motion blur masking based on the estimated motion blur; determining, by the computing system, a motion blur kernel to correct motion blur for the image captured during the exposure time based on the estimated motion blur; processing, by the computing system, the motion blur kernel with one or more polynomial filters to generate a sharpening kernel, wherein the sharpening kernel comprises one or more terms for controlling at least one of frequency amplification or noise amplification; and generating, by the computing system, an augmented image by applying the sharpening kernel and the motion blur masking to the image.
