Abstract
Embodiments herein include a focus evaluator configured to categorize portions of image content into different groupings depending on a respective focus value derived for each portion of the image content. The focus evaluator compares relative sizes of the different groupings to identify one or more groupings representative of an overall focus quality associated with the image content. Based on the identified one or more groupings, the focus evaluator generates the overall focus value for the image content.
