  • Patent number: 12368814
    Abstract: Described are methods and systems that determine bokeh ratio of a camera, such as a webcam in an information handling system. A focal point and bokeh point are determined for the camera. An image of a Siemens star chart (star chart) is captured by the camera at the bokeh point. The diameter of the captured image of the star chart and diameter of blur circle in the image of the star chart are measured. The ratio of the diameter of the blur circle to the diameter of the captured image of the star chart is correlated to the bokeh ratio of the camera.
