Automaatteravustamismehanismis jaotatakse valgus läätsekoostu abil kaheks eraldi pildiks, millest üks pilt moodustatakse esimese tajuri jaoks ja teine teise tajuri jaoks ning kui kahe pildi vahekaugus ei ole õige, saadetakse objektiivi mootorile signaal, et objekt teravaks fookusesse tuua.
In the autofocus mechanism, the light is divided into two separate images by a lens assembly, one image is formed for the first sensor and the other for the second sensor, and if the distance between the two images is not correct, a signal is sent to the lens motor to bring the object into sharp focus.
