A camera device with multiple lens units and having a function of changing focus automatically comprises: a camera unit with multiple lens units, an image display screen and an image control circuit. The camera unit includes a lens assembly with a plurality of lens units, a base tightly adhered to a back of the lens frame, an image sensor is installed on the base at a position with respect to the lens cavity; and at least one passive sensor being set with different sensing length which is exactly matched with the focus or visual angle of each lens set. The image control circuit is installed between the camera unit and the image display screen and has a detecting signal judging portion, a priority image operation portion, and an image display execution portion. The image display execution portion receives the signals from the detecting signal judging portion or priority image operation portion, and then receives images of a specific lens, and then actuates a screen and displaying the image on the screen. After displaying the image on the screen through a time period, then the operation is stopped. Thereby, the focusing and adjusting structure of a camera device is simplified. The lifetime is prolonged and the cost is reduced.
