Method for performing color interpolation on a down-sampled bayer image, and associated device

A device for performing color interpolation on a down-sampled Bayer image, the device comprising:

• at least one pixel prediction module, wherein with regard to at least one pixel to be interpolated in the down-sampled Bayer image, the at least one pixel prediction module performs at least one pixel prediction operation according to pixel values of a plurality of neighboring pixels kept by a down-sampling operation, in order to generate at least one simulation pixel value of at least one corresponding simulation pixel of at least one neighboring pixel discarded by the down-sampling operation;
• and
• at least one color interpolation module arranged to perform at least one color interpolation operation according to at least one pixel value of at least one neighboring pixel kept by the down-sampling operation and the at least one simulation pixel value, in order to generate a pixel value of the at least one pixel to be interpolated.
