Abstract
An automated RAW image processing method and system are disclosed. A computer receives a RAW image and metadata from a camera and interpolates an interpolated image from the RAW image so that the interpolated image is in a first color space. Predefined characterization matrices associated with the camera are obtained. Each of the characteristic matrices is associated with a different illuminant. A conversion matrix is interpolated from the characterization matrices and a white balance of the RAW image. The interpolated image is converted with the conversion matrix into a second color space. A resulting image in a rendered color space is produced from the converted image, and the resulting image is made available to an application program.
