摘要： An apparatus and a method for efficiently executing correction of false color, such as purple fringe, caused by chromatic aberration and for generating and outputting high-quality image data are provided. A white-saturated pixel is detected from image data, a false-color-pixel detection area is set around the detected white-saturated pixel, and pixels having color corresponding to false color such as purple fringe are detected from the set area. The detected pixels are determined as false-color pixels and correction processing based on the values of the surrounding pixels is performed on the determined false-color pixels. With this configuration, an area of false color such as purple fringe generated in the neighborhood of a white-saturated pixel can be efficiently detected, pixel values can be partially corrected, and high-quality image data can be generated and output without affecting the entire image.

摘要： A projected image of a three-dimensional object is displayed in a frame which is a constituent of a moving picture. Shape information concerning the shape of a surface of the three-dimensional object and a characteristic point on the projected image of the surface are designated. The projected image of the surface of the three-dimensional object is transformed into a corresponding two-dimensionally developed expanded image. Rendering is effected on an overall expanded image storage area that stores the entire part of the expanded image of the surface. A predetermined cut-out region is cut out of the overall expanded image storage area, and a retouching work such as an editorial work is effected on the expanded image, based on the content of the cut-out region. The retouched expanded image is then re-transformed back to the projected image on the frame. Three-dimensional retouching such as a three-dimensional editorial work can therefore easily be effected on a two-dimensional moving picture.
