Abstract
The present disclosure relates to a technique for selectively reproducing multiple sounds for respective areas of a display through image analysis for each display area. A technique, for individually controlling multiple audio devices by analyzing an image to extract regions of the image and classifying sound types through data learning, can be provided.
Claims17
A display control circuit comprising:
- an image analysis circuit configured to analyze features of each region of an input image provided to an audio/video device;
- a sound analysis circuit configured to analyze input sound provided to the audio/video device in a frequency domain and a time domain and generate object sound information;
- a multi-sound generation circuit configured to generate multi-sound information by matching the object sound information to the features of each region from the image analysis circuit;
- and
- a sound control circuit configured to individually control sound for each area of the audio/video device according to the multi-sound information,
- wherein the image analysis circuit is configured to extract keypoints of the image by applying a feature extraction algorithm to an entire region of the input image, and cluster the keypoints and determine local regions comprising clusters to primarily classify objects present in the input image.
