1. A handheld magnification device for displaying a magnified representation of an object in a see-through manner, the handheld magnification device comprising: a casing having a camera face for pointing toward the object and a display face opposite to the camera face; a first and a second camera both adapted to acquire an image of the object, each camera having a corresponding field of view extending from the camera face of the casing, the first camera having a first working range proximate the handheld magnification device and the second camera having a second working range different from and extending beyond the first working range; a distance-sensitive sensor for measuring in real-time a distance parameter representative of a distance between the object and the handheld magnification device; a processing unit for receiving the distance parameter from the distance-sensitive sensor and for automatically selecting, based on the distance parameter and the first and second working ranges, one of the first and second cameras as a selected camera; and a display extending along the display face of the casing for displaying, in real-time, the magnified representation of the object based on the image acquired by the selected camera.
