Digital image exposure correction

A computer readable storage device comprising instructions to process an image, the instructions comprising:

• instructions to receive the image from an image capture device;
• instructions to determine a region of interest of a thumbnail of the image;
• instructions to calculate a likelihood that the region of interest influences exposure correction of the image;
• instructions to extract, from the image, values of at least one feature, wherein the at least one feature is a feature derived from the region of interest;
• instructions to determine an exposure correction of the image based on the extracted values;
• and
• instructions to correct the image by the determined exposure correction to produce an exposure-corrected image.

A system for processing an image, the system comprising:

• means for receiving the image from an image capture device;
• means for determining a region of interest of a thumbnail of the image;
• means for calculating a likelihood that the region of interest influences exposure correction of the image;
• means for extracting, from the image, values of at least one feature, wherein the at least one feature is a feature derived from the region of interest;
• means for determining an exposure correction of the image based on the extracted values;
• and
• means for correcting the image by the determined exposure correction to produce an exposure-corrected image.
