Abstract

A method of operating a data processing apparatus is provided. The method includes receiving video data; receiving a virtual test signal representative of a location of a virtual object; setting data representing the horizontal and vertical size of the virtual object dependent upon the location of the virtual object; overlaying the received video data with an image of the virtual object at locations determined from the virtual test signal to generate virtual test video data; and analysing the virtual test video data and generating an alarm signal based on an output signal generated by said analysis.

Claims

1. A method of operating a data processing apparatus comprising:

receiving video data;

receiving a virtual test signal representative of a location of a virtual object;

setting data representing a horizontal size and a vertical size of the virtual object dependent upon a location of the virtual object;

overlaying the received video data with an image of the virtual object at locations determined from the virtual test signal to generate virtual test video data; and

analysing the virtual test video data and generating an alarm signal based on an output signal generated by said analysis.

2. The method of claim 1, further comprising:

responding to user input to display in an image of a scene displayed on a display screen the virtual object representative of a real size object to establish a first datum position and to store data defining the first datum position;

varying a size of the virtual object in the image responsive to the user input;

storing the data representative of the horizontal size and the vertical size of the virtual object relative to the displayed image at the first datum position;

displaying said virtual object at a second datum position in said image responsive to the user input and to store data defining the second datum position;

varying the size of the virtual object on the display screen at the second datum position responsive to user input; and

storing data representative of the vertical size and the horizontal size of the virtual object at the second datum position relative to the displayed image.

3. The method of claim 1, wherein the received video data is pre-recorded video data retrieved from computer memory.

4. The method of claim 1, wherein the virtual object is representative of an object that has been captured from the video data.

5. The method of claim 1, further comprising receiving at least one of audio data and external data, and wherein analysing the virtual test video data further comprises analysing the received at least one of audio data and external data and generating the alarm signal based on the output signal generated by said analysis.

6. Data processing apparatus comprising:

a video data receiver configured to receive video data;

a virtual test signal receiver configured to receive a virtual test signal representative of a location of a virtual object;

a video overlay engine configured to overlay the received video data with the virtual object at locations determined from the virtual test signal to generate virtual test video data, wherein the video overlay engine is configured to set data representative of a horizontal size and a vertical size of the virtual object dependent upon the location of the virtual object; and

an alarm engine configured to analyse the virtual test video data and generate an alarm signal based on an output signal generated by said analysis.

7. The data processing apparatus of claim 6 which is operative to:

respond to user input by displaying in an image of a scene displayed on a display screen the virtual object representative of a real size object to establish a first datum position and to store data defining the first datum position;

vary a size of the virtual object in the image responsive to the user input;

store data representative of the horizontal size and the vertical size of the virtual object relative to the displayed image at the first datum position;

display said virtual object at a second datum position in said image responsive to the user input and to store data defining the second datum position;

vary the size of the virtual object on the display screen at the second datum position responsive to the user input; and

store data representative of the vertical size and the horizontal size of the virtual object at the second datum position relative to the displayed image.

8. The data processing apparatus of claim 6, wherein the received video data is pre-recorded video data retrieved from computer memory.

9. The data processing apparatus of claim 6, wherein the virtual object is representative of an object that has been captured from the video data.

10. The data processing apparatus of claim 6, further comprising at least one of an audio data receiver and an external data receiver configured to receive at least one of audio data and external data, respectively, and wherein the alarm engine is further configured to analyse at least one of the received audio data and external data, respectively, to generate the alarm signal.

11. A carrier carrying a computer program comprising non-transitory processor-implementable instructions for causing a computer to perform a method comprising:

receiving video data;

receiving a virtual test signal representative of a location of a virtual object;

setting data representing a horizontal size and a vertical size of the virtual object dependent upon the location of the virtual object;

overlaying the received video data with an image of the virtual object at locations determined from the virtual test signal to generate virtual test video data; and

analysing the virtual test video data and generating an alarm signal based on an output signal generated by said analysis.

12. The carrier of claim 11, wherein the program further comprises instructions for causing the computer to perform the method further comprising:

responding to user input to display in an image of a scene displayed on a display screen the virtual object representative of a real size object to establish a first datum position and to store data defining the first datum position;

varying a size of the virtual object in the image responsive to the user input;

storing data representative of the horizontal size and the vertical size of the virtual object relative to the displayed image at the first datum position;

displaying said virtual object at a second datum position in said image responsive to the user input and to store data defining the second datum position;

varying the size of the virtual object on the display screen at the second datum position responsive to the user input; and

storing data representative of the vertical size and the horizontal size of the virtual object at the second datum position relative to the displayed image.

13. The carrier of claim 11, wherein the received video data is pre-recorded video data retrieved from a computer memory.

14. The carrier of claim 11, wherein the virtual object is representative of an object that has been captured from the video data.

15. The carrier of claim 11, wherein the program further comprises instructions for causing the computer to perform the method further comprising receiving at least one audio data and external data, and wherein analysing the virtual test video data further comprises analyzing the received at least one of audio data and external data, respectively, and generating an alarm signal based on an output signal generated by said analysis.
