DEVICE, SYSTEM AND METHOD FOR MULTI-POINT FOCUS

摘要

An electronic device achieving multi-point focus of a scene includes a digital camera, a depth-sensing camera, at least one processor, a storage device, a display device, and a multi-point focus system. The system receives one or more points designated by a user from an image of a scene previewed by the digital camera, and analyzes the one or more designated objects to be focused. Distances between the digital camera and each designated object to be focused are determined and the digital camera adjusts a focal length according to each distance. Images of the same scene at each focal length are captured and the images captured by the digital camera are processed to generate a new image which includes all of focus objects. The new image is output through the display device.

主权项

1. An electronic device, comprising a digital camera, a depth-sensing camera, at least one processor, a storage device, and a display device, each of which connects to each other using data bus; the electronic device further comprising a multi-point focus system, wherein the multi-point focus system comprises one or more programs stored in the storage device, which when executed by the at least one processor, cause the processor to:
receive one or more points designated by a user from an image of a scene previewed by the digital camera; analyze one or more objects to be focused according to the one or more designated points; obtain a distance between the digital camera and each of the one or more objects to be focused from the depth-sensing camera; control the digital camera to adjust a focal length according to each of distances, and capture images of the scene at each of focal lengths; process the captured image, and generate a new image which includes all of focus objects based on the processed image; and control the display device to display the new image.
