Check left/right and readable text
Mirror ON: raise your right hand. It should move below the R marker on the right. Toggle Mirror if the movement feels reversed.
Readable text: Mirror ON intentionally reverses writing. Switch Mirror OFF before reading or saving a document, label, or sign.
Privacy: the video stream stays in your browser. Nothing is uploaded, recorded, or sent to a server.
Resolution describes the frames displayed by this browser. Preview FPS is measured from delivered video frames when supported, otherwise it uses the browser-reported track setting. Lighting, USB bandwidth, browser load, and other camera apps can lower both values; this is not a test of the camera’s advertised maximum.
Camera & image
Brightness and contrast change only how the preview is displayed; the camera signal itself is untouched.
