Patent number: 7561189Abstract: 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.

Patent number: 7532773Abstract: 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.
