Image analysis device, image analysis method for telecommuting work security and terminal device including the same

An image analysis method comprising:

• generating, by an image converter, target image frames based on video image frames captured by a terminal device;
• generating a plurality of analysis results by a plurality of image analyzers respectively comprising a plurality of image analysis models, the plurality of image analyzers analyzing the target image frames respectively using the plurality of image analysis models different from each other;
• performing a respective analysis scheduling independently regardless of analysis execution states of other image analyzers;
• and
• determining a security mode of the terminal device based on the plurality of analysis results,
• wherein at least one image analyzer of the plurality of image analyzers is configured to omit an analysis of a target image frame that is received from the image converter before the at least one image analyzer completes an analysis of a previous target image frame of the target image frames.

A terminal device comprising:

• a display device;
• a camera configured to generate video image frames captured by the display device;
• an image analysis device configured to determine a security mode based on the video image frames;
• a security module configured to, based on the security mode, restrict a display of security data through the display device;
• and
• a security state determiner configured to determine the security mode of the terminal device based on a plurality of analysis results,
• wherein the image analysis device comprises:
• an image converter configured to generate target image frames based on the video image frames;
• and
• a plurality of image analyzers respectively comprising a plurality of image analysis models and configured to:
• generate the plurality of analysis results by analyzing the target image frames respectively using the plurality of image analysis models different from each other, and perform a respective analysis scheduling independently regardless of analysis execution states of other image analyzers,
• wherein at least one image analyzer of the plurality of image analyzers is further configured to omit an analysis of a target image frame that is received from the image converter before the at least one image analyzer completes an analysis of a previous target image frame of the target image frames.
