Abstract

A method for censoring inappropriate images during a video call is disclosed. The method includes: receiving, from a first terminal, a stream including a plurality of images captured by the first terminal; attempting to detect a face in each of one or more sample images selected among the plurality of images included in the stream; determining that the face has not been detected in at least some of the sample images; performing image processing on at least one of the plurality of images included in the stream; and displaying the plurality of images included in the stream.

First claim

What is claimed is:

1. A method of a video call, the method comprising:
receiving, by a first mobile terminal, a video stream from a second mobile terminal with which the first mobile terminal has established a video call session;
displaying, on a display of the first mobile terminal, a series of images of the video stream during the video call session;
processing, by the first mobile terminal, at least part of the series of images to determine whether a human face is contained therein; and
further processing, by the first mobile terminal, to display the series of images such that:
(1) when it is determined, by the first mobile terminal, that a human face of a user is contained in a first one of the series of images, the first mobile terminal displays the first image on the display,
(2) when it is determined, by the first mobile terminal, that the human face of the user is not contained while a body part of the user is contained in a second one of the series of images that is received subsequent to the first image, the first mobile terminal applies a first visual effect to the second image to prevent the body part of the user from being exposed when displaying the second image,
(3) when it is determined, by the first mobile terminal, that the human face of the user is still not contained while the body part of the user is contained in a third one of the series of images that is subsequent to the second image, the first mobile terminal applies the first visual effect to the third image to prevent the body part of the user from being exposed when displaying the third image, and
(4) when it is determined, by the first mobile terminal, that the human face of the user is contained in a forth one of the series of images that is subsequent to the third image, the first mobile terminal displays the forth image without applying the first visual effect thereto.

2. The method of claim 1 , wherein the first mobile terminal analyzes the first image to determine a skin color of the human face, wherein the first mobile terminal applies the first visual effect on an area of the second image containing the skin color.

3. The method of claim 1 , wherein the first visual effect comprises at least one selected from a group consisting of a blur effect, a mosaic effect, substituting with another image, and adjusting of color, brightness, contrast, or saturation.

4. A non-transitory computer-readable recording medium having recorded thereon a program for executing the method of claim 1 .
