Abstract:
1. In a video processing system, a method for transforming an original image into a new image, the original image and the new image being both conformed with a Bayer pattern, the original image comprising M rows of original data, the new image comprising Q rows of new data, M and Q being positive integers larger than or equal to 1, a memory being previously provided, a first index i being larger than or equal to 1 and smaller than or equal to (M/2−1), a second index j being larger than or equal to 1 and smaller than or equal to (Q/2), said method comprising the steps of: (a) based on the (2i−1)th row of original data among the M rows of original data, generating a (2i−1)th row of intermediate data and storing the (2i−1)th row of intermediate data into said memory; (b) based on the (2i)th row of original data among the M rows of original data, generating a (2i)th row of intermediate data and storing the (2i)th row of intermediate data into said memory; (c) based on the (2i+1)th row of original data among the M rows of original data, generating a (2i+1)th row of intermediate data, during the process of generating the (2i+1)th row of intermediate data, simultaneously generating the (2j−1)th row of new data among the Q rows of new data based on the (2i−1)th and (2i+1)th rows of intermediate data, and storing the (2i+1)th row of intermediate data into said memory to replace the (2i−1)th row of intermediate data; and (d) based on the (2i+2)th row of original data among the M rows of original data, generating a (2i+2)th row of intermediate data, during the process of generating the (2i+2)th row of intermediate data, simultaneously generating the (2j)th row of new data among the Q rows of new data based on the (2i)th and (2i+2)th rows of intermediate data, and storing the (2i+2)th row of intermediate data into said memory to replace the (2i)th row of intermediate data; whereby, the Q rows of new data in the new image are sequentially generated and the original image is transformed into the new image.
