Abstract: This application discloses a method for reducing an occlusion effect of an earphone, and a related apparatus. The method is applied to an earphone having at least one microphone and a speaker. The method includes: detecting occurrence of at least one of the following events: a user speaks and the user is in a motion state; and triggering at least one of the following operations in response to the at least one event: processing the user's sound signal based on the at least one microphone to suppress an occlusion effect of the earphone, and playing an audio by using the speaker, to mask a sound signal in the user's auditory canal. Embodiments of this application can reduce or even eliminate the earphone occlusion effect, to improve user experience.

Abstract: Embodiments of the present invention provide a method and a device for generating a morphing animation from multiple images, where the method includes: performing hue preprocessing on adjacent images among multiple images; determining the quantity of intermediate frames between the adjacent images according to a feature point differential of the adjacent images on which the hue preprocessing has been performed, generating, between the adjacent images through an image warping technology, intermediate frame images, the quantity of which is the same as that of the intermediate frames, insert the intermediate frame images between the adjacent images, and generate a morphing animation from the multiple images and the intermediate frame images that are inserted between all adjacent images among the multiple images. The morphing animation generated in the present invention is smooth and natural, thereby improving a morphing effect of the morphing animation.
