<p>The method involves transforming a raw digital image (10) by applying a low frequency local convolution kernel (S) and high frequency local convolution kernels (V, H, D) to pixels of the image for obtaining a low frequency co-efficient image (10S) and high frequency co-efficient images (10V, 10H, 10D), where the kernels are square matrices of four pixels or Haar wavelets. A luminance image is reconstructed using the low frequency co-efficient image. Chrominance images are reconstructed using the high frequency co-efficient images. Independent claims are also included for the following: (1) a computer program comprising instructions for implementing a raw digital image demosaicing method (2) a graphic circuit or an imaging circuit of an image sensor, comprising a processor for implementing the raw digital image demosaicing method.</p> |
