摘要： 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.

摘要： A rapid color recognition method is provided. In the method, an area for representing a color of the pixel is identified according to the basic color component data of the pixel, and then the color code is outputted according to a predetermined color classification table of the area. In the method, since an isosceles right triangle plane is provided by extending and scaling the regular triangle plane by using one side of the regular triangle plane as a base, wherein the regular triangle plane is provided by normalizing the basic color component data. Therefore, the basic color component data is normalized without division operation, and thus the complexity of the operation of the color recognition is reduced.
