Patent ID: 8599280

Claim:
A multiple source automatic white balancing method, the method comprising: performing a first image processing on a subject image and generating a first processed image; performing a second image processing on the subject image and generating a second processed image; and generating a third processed image by blending the first and second processed images together based on an output of an outdoor weight map function, wherein the first image processing is performed using parameters associated with indoor lighting, and the second image processing is performed using parameters associated with outdoor lighting, generating the third processed image includes determining the output of the outdoor weight map function for each of a plurality of sections of the subject image, and forming each of a plurality of a sections of the third image by blending a corresponding section of the first processed image with a corresponding section of the second image based on the output of outdoor weight map function associated with a corresponding section of the subject image, and determining the output of the outdoor weight map function for each of a plurality of sections of the subject image includes determining a brightness value for each of the plurality of sections; comparing the brightness value to upper and lower brightness thresholds for each of the plurality of sections; selecting one of a high brightness outdoor weight function, a low brightness outdoor weight function, and a combination of the high and low brightness outdoor weight functions based on the comparison; and generating the output based on the selected function.
