Claim:
1. A method for processing sensor data in an image processor that implements at least one image enhancement process, the method comprising: receiving sensor data from an image sensor; performing a skin tone detection operation to identify skin tone areas in the sensor data in pre-capture processing; selectively modifying at least one image enhancement process for the identified skin tone areas prior to image capture; applying the at least one modified image enhancement process to the identified skin tone areas in the sensor data to generate modified sensor data; feeding the modified sensor data back to the image sensor, thereby enabling the image sensor to capture an image using the modified sensor data; wherein each step is performed in the image processor; dividing the sensor data into blocks of pixels and calculating a percentage of the skin tone area within each block of pixels; and determining a weighting scheme, wherein the weighting scheme assigns weights to the at least one image enhancement process based on the percentage of the skin tone area within each block of pixels, and wherein the at least one image enhancement process is modified based on the weights assigned.
