Unlocking custom resolutions in USB cameras can be achieved through techniques like binning and cropping. Binning involves combining multiple pixels into one to improve low-light performance and increase frame rates, though it reduces resolution. Cropping allows you to capture a smaller area of the sensor, effectively increasing the frame rate while lowering resolution. These techniques give users greater control over the camera\'s output, allowing for tailored resolutions suited to specific applications. Whether for industrial, scientific, or creative use, they provide flexibility to optimize performance based on individual needs.
