  • Patent number: 11140327
    Abstract: An image-capturing device includes a camera module and a controller. The camera module captures an image of an object. The camera module includes a first camera and a second camera. The first camera has a first field of view (FOV) and captures an image in the first FOV, so as to produce a first image. The second camera is adjacent to the first camera and has a second FOV, in which the first FOV is wider than the second FOV. The second camera captures an image in the second FOV, so as to produce a second image. A displayer displays one of the first and second images. When a zoom ratio of the first image increases, the controller selects a display region in the first image according to an object distance, such that the display region is enlarged and then displayed on the displayer.
