Abstract: A method and an apparatus of image dynamic response re-mapping and a digital camera using the same. The apparatus first transforms an original Bayer image data into new transformed image data on a new image coordinate system, and then performs dynamic response re-mapping for the new transformed image data to calculate a gain modulated value. Finally, the apparatus adjusts the original Bayer image data according to the gain modulated value and outputs adjusted Bayer image data with dynamic response re-mapping. Because the apparatus transforms the original Bayer image data into the new transformed image data on the new image coordinate system in advance, it can reduce the bad effect on performing the dynamic response re-mapping on a high-frequency color signal and also keep the color coherence in color processing.

Abstract: A directional interpolation method and device for increasing resolution of an image is disclosed. The device includes an input terminal, a memory, a texture analysis module, a texture variance consistence module and an interpolation module. The input terminal receives signals representing the pixels of the image. The memory stores the pixels in row direction.
