Abstract

A mechanism for generating a 16:9 aspect ratio video image or other non-standard format video for transmission to an application expecting a standard 4:3 image. Software or firmware is inserted between the camera and the application. The image is cropped to obtain the desired aspect ratio (e.g., 4:3 is cropped to give 16:9). Black bars of pixels are added outside the cropped image to make it an actual 4:3 format. A pop-up assistant appears when the target application (e.g., an instant messenger application) is launched, with the assistant providing the controls for switching to 16:9 or other non-standard format.

Claims

1. An apparatus for modifying the aspect ratio of a video image, comprising:

a video feed input for providing a video image in an original aspect ratio format;

a transformation engine for modifying a received image, said transformation engine being located between said video feed input and a user application for said video;

a user input for indicating a desired image aspect ratio;

wherein said transformation engine, responsive to said user input, modifies said video image by substituting groups of black pixels for areas of said video image to give the desired aspect ratio in a region of said video image not covered by said black pixels; and

wherein said transformation engine provides a transformed video image to said user application in said original aspect ratio format.

2. The apparatus of claim 1 further comprising:

a quick assistant module for providing a quick assistant user interface on a screen proximate a window for said user application, said quick assistant providing a user interface for said user input.

3. The apparatus of claim 1 wherein said user application is an instant messenger application.

4. The apparatus of claim 1 wherein an aspect ratio selectable by a user includes 16:

9, and said original aspect ratio is 4;

3.

5. An apparatus for modifying the aspect ratio of a video image, comprising:

a video feed input for providing a video image in an original aspect ratio format;

a transformation engine for modifying a received image, said transformation engine being located between said video feed input and a user application for said video;

a user input for indicating a desired image aspect ratio;

wherein said transformation engine, responsive to said user input, modifies said video image by substituting groups of black pixels for areas of said video image to give the desired aspect ratio in a region of said video image not covered by said black pixels; and

wherein said transformation engine provides a transformed video image to said user application in said original aspect ratio format;

a quick assistant module for providing a quick assistant user interface on a screen proximate a window for said user application, said quick assistant providing a user interface for said user input;

wherein said user application is an instant messenger application; and

wherein an aspect ratio selectable by a user includes 16;

9, and said original aspect ratio is 4;
