CAMERA AND AUTO-FOCUSING METHOD OF THE CAMERA
First Claim
1. A camera, comprising:
- a depth-sensing lens, an auto-focusing apparatus, and a display screen;
at least one microprocessor; and
a storage device for storing one or more computer-readable programs, which when executed by the at least one microprocessor, cause the at least one microprocessor to;
drive the auto-focusing apparatus to move the depth-sensing lens aiming at a scene, and show images of the scene on the display screen;
determine a focusing position of the depth-sensing lens when an object is selected from the scene shown on the display screen;
sense a depth between the object of the scene and the camera using the depth-sensing lens;
determine a distance between the object of the scene and the focusing position of the depth-sensing lens;
calculate an optimal focus of the camera according to the depth and the distance;
drive the auto-focusing apparatus to move the depth-sensing lens from the focusing position of the depth-sensing lens to the optimal focus of the camera; and
controlling the depth-sensing lens to capture an image of the scene based on the optimal focus of the camera when a button of the camera is pressed.

Abstract
A camera includes a depth-sensing lens, an auto-focusing apparatus, and a display screen. In an auto-focusing method of the camera, a focusing position of the depth-sensing lens is determined when an image of the scene is shown on the display screen. The depth-sensing lens senses a depth between the object and the camera, and determines a distance between the object and the focusing position of the depth-sensing lens. An optimal focus of the camera is calculated according to the depth and the distance. The auto-focusing apparatus controls the depth-sensing lens to move from the focusing position to the optimal focus of the camera. The camera controls the depth-sensing lens to capture an image of the scene based on the optimal focus when a user presses a button of the camera.
