Abstract
A method of adjusting exposure settings for a digital camera includes searching at least a portion of the field of view of the camera for pixels having a flesh tone. The flesh tone pixels are analyzed to identify at least one flesh tone spot. Spot metering of the field of view of the camera is carried out such that at least one flesh tone spot is given greater weight than the rest of the field of view. Then, the exposure settings are adjusted based on the spot metering.
