Abstract: A method and apparatus for enhancing the resolution of digital images. For each image a white balanced image is generated, which takes into account the differences in the colors of the sensor cell upon which the values are generated. Edge detection filters are then activated on the white balanced image and a weight is determined, indicating the probability that a feature which was detected as an edge is indeed an edge. At the last step, each detected edge is multiplied by the probability and is added to the luminance component, thus enhancing the edges. Preferred embodiments of the white balance image generation. Generating the white balanced image, detecting the edges and determining the weights are disclosed for sensors operating in Line Addition On mode and for sensors operating in Line Addition Off mode.
