Image processing system with three-dimensional viewing and method of operation thereof

1. A method of operation of an image processing system comprising:

receiving an original image;

receiving a first position of a viewer from a position detector;

receiving a second position of the viewer from the position detector;

calculating a cropping offset for the original image based on the first position and the second position;

calculating a cropped image by cropping the original image by the cropping offset; and

displaying the cropped image on a display unit, wherein the cropping offset is based on an original image width, a display unit width, a viewer movement, a viewer distance from the position detector, a diagonal size of the display unit and a shifting constant, wherein calculating the cropping offset includes calculating the cropping offset p as:

2. The method as claimed in claim 1 , wherein calculating the cropped image includes cropping the original image on the left side.

3. The method as claimed in claim 1 , wherein calculating the cropped image includes cropping the original image on the right side.

4. The method as claimed in claim 1 , wherein displaying the cropped image includes:

calculating a top offset and a bottom offset based on the cropping offset for maintaining the aspect ratio of the display unit;

calculating the cropped image by cropping the original image by the top offset from the top of the original image; and

calculating the cropped image by cropping the original image by the bottom offset from the bottom of the original image.

5. A method of operation of an image processing system comprising:

receiving an original image;

receiving a first position of a viewer from a position detector; receiving a second position of the viewer from the position detector;

calculating a viewer movement based on the horizontal distance between the first position and the second position;

calculating a cropping offset for the original image based on the viewer movement;

calculating a cropped image by cropping the original image by the cropping offset; and

displaying the cropped image on a display unit, wherein the cropping offset is based on an original image width, a display unit width, a viewer movement, a viewer distance from the position detector, a diagonal size of the display unit and a shifting constant, wherein calculating the cropping offset includes calculating the cropping offset p as:

7. The method as claimed in claim 5 , wherein calculating the cropped image includes cropping the original image on the right side.

8. The method as claimed in claim 5 , wherein displaying the cropped image includes:

calculating a top offset and a bottom offset based on the cropping offset for maintaining the aspect ratio of the display unit;

calculating the cropped image by cropping the original image by the top offset from the top of the original image; and

calculating the cropped image by cropping the original image by the bottom offset from the bottom of the original image.

9. An image processing system comprising:

a get original image module for receiving an original image;

a viewer detection module, coupled to the get original image module, for receiving a first position and a second position of a viewer;

a crop image module, coupled to the position detector, for calculating a cropping offset for the original image based on the first position and the second position, and for calculating a cropped image by cropping the original image by the cropping offset; and
