Title: CAMERA ASSEMBLY, METHOD FOR PORTRAIT TRACKING BASED ON THE SAME, AND ELECTRONIC DEVICE
Abstract:
A camera assembly, a method for portrait tracking based on the camera assembly, and an electronic device are provided. The camera assembly (10) includes: a first camera (100); a first motor (200) for driving the first camera (100) to move; a second camera (300), comprising a plurality of pixel blocks (310), each pixel block (310) being formed of a plurality of photosensitive pixels (311) and being configured to obtain a first photodiode pixel by capturing a portrait area through a first part of the plurality of photosensitive pixels (311) and to obtain a second photodiode pixel by capturing the portrait area through a second part of the plurality of photosensitive pixels (311) when a face is detected; a controller (400), configured to obtain a global photodiode pixel, to calculate a phase difference according to the global photodiode pixel, and to control the first motor (200) to drive the first camera (100) to move to an in-focus position according to the phase difference.
