Abstract
A method for sampling a Bayer image having two dimensional planes of red, green and blue pixels, the method including the steps of: rotating the green plane by 45 degrees; sequentially sampling an m×m pixel block of the rotated image, where m is an integer greater than 1; providing an address for the m2 samples by determining a starting address for a first of the samples and thereafter applying a predetermined fixed sequence of offsets to obtain the addresses of the remaining samples.

A method for sampling a Bayer image having two dimensional planes of red, green and blue pixels, the method including the steps of:
- rotating the green plane by 45 degrees;
- sequentially sampling an m×m pixel block of the rotated image, where m is an integer greater than 1;
- providing an address for the m2 samples by determining a starting address for a first of the samples and thereafter applying a predetermined fixed sequence of offsets to obtain the addresses of the remaining samples.
An apparatus for sampling a Bayer image having two dimensional planes of red, green and blue pixels, the apparatus including:
- input means for rotating the green plane by 45 degrees;
- processing means for sequentially sampling an m×m pixel block of the rotated image, where m is an integer greater than 1;
- address means for providing an address for the m2 samples by determining a starting address for a first of the samples and thereafter applying a predetermined fixed sequence of offsets to obtain the addresses of the remaining samples.
