Abstract: A camera device is provided, which includes an image sensor and an optical lens arranged corresponding to the image sensor. An axis is defined on the light incident surface of the image sensor. The edge of the optical lens includes a straight segment that is parallel to the axis. Since the non-effective area of the optical lens is decreased, the camera module has a smaller size.
