Abstract
An electronic device is provided. The electronic device includes: an inertial measurement unit, a camera device, and a processor. The inertial-measurement unit is configured to detect a pitch angle of the electronic device. The camera device is configured to focus on a target object to capture an object image. The processor is configured to execute an image-distance-measuring program to perform the following steps: obtaining a lens-focal-length parameter corresponding to the object image from an operating system performed by the electronic device; calculating a plurality of terminal parameters corresponding to the pitch angle according to the lens-focal-length parameter and the pitch angle; converting the terminal parameters to a plurality of linear parameters; and calculating an object distance between the target object and the camera device according to a linear equation of the linear parameters, and the upper focusing distance, and the lower focusing distance.
