Abstract

A method for image scaling and shifting on a display unit comprises steps of: providing a first image to display on the display unit, in order to complete the shown on the display unit, the first image and the display unit having the same size of a length of x and a width of y; according to rotating the display unit with 90 degrees, transforming the first image with 90 degrees and scaling the first image to form a second image; the second image having a width of x and a length of x²/y; displaying a first part of the second image on the display unit; according to a shaking action, shifting a second part of the second image onto the display unit; wherein lengths of first part and the second part of the second image are x, and widths of both of them are y.

Claims

1. A method for image scaling and shifting on a display unit, comprising steps of:

providing a first image to display on said display unit, in order to complete the shown on said display unit, said first image and said display unit having the same size of a length of x and a width of y;

according to rotating said display unit with 90 degrees, transforming said first image with 90 degrees and scaling said first image to form a second image;

said second image having a width of x and a length of x²/y;

displaying a first part of said second image on said display unit;

according to a shaking action, shifting a second part of said second image onto said display unit;

wherein lengths of said first part and said second part of said second image are x, and widths of both of them are y.

2. The method according to claim 1 wherein a G sensor detects said display unit for rotating and shaking.

3. The method according to claim 1 wherein said display unit is on a mobile phone.

4. The method according to claim 1 wherein said display unit is on a digital camera.

5. The method according to claim 1 wherein said display unit is on an e-book.

6. The method according to claim 1 wherein said display unit is on a personal digital assistant (PDA).

7. The method according to claim 1 wherein said display unit is on a digital photo album.

8. The method according to claim 1 wherein said display unit is shaken left or right.
