Yes. A practical way is to photograph a known straight vertical line while it moves at a constant speed, then measure how much the line is skewed or bent in the image.

One simple setup is to print a straight vertical line and mount it on a turntable spinning at a fixed rate, such as 45 rpm. Frame the shot so the image includes from the center toward the edge of the record’s path. Because the line’s motion is predictable, any bending or slant in the captured line is caused by rolling shutter readout.

More distortion means slower sensor readout. With the same setup, you can compare different cameras—or different shooting modes on the same camera—even if focal length changes, as long as you keep the geometry consistent enough for comparison.

In general, rolling shutter severity is tied to frame readout time: faster readout behaves more like a global shutter, while slower readout shows more skew with motion. Motion speed also matters: faster-moving subjects make the effect more obvious.
