Title:
METHOD AND APPARATUS FOR DETERMINING IMAGE FOCUSING REGION
Document Type and Number:
WIPO Patent Application WO/2020/118503
Kind Code:
A1
Abstract:
A method and apparatus for determining an image focusing region. The method comprises: acquiring an original video file, wherein the original video file comprises a video image stream and an audio stream (S11); generating a scene analysis heat map according to the video image stream and the audio stream (S12), wherein the scene analysis heat map is used for indicating the probability of a sound existing on each image unit from among multiple image units on a target image frame of the video image stream; and determining, according to the scene analysis heat map, at least one image focusing region, meeting a preset condition, on the target image frame of the video image stream (S13), wherein each image region in the at least one image focusing region comprises at least one image unit. The present method can determine a region, where a sound is most possibly produced, on a target image frame of a video image stream; moreover, other than an image collection apparatus and a sound collection apparatus, no extra devices need to be added to a terminal, thereby reducing the cost of the devices.
