Method and apparatus for prioritizing image quality of a particular subject within an image

摘要

A device capable of digital imaging detects multiple faces in image data received from an image sensor, performs pattern recognition to check if at least one of the detected faces is a priority face belonging to a ranked set of reference faces, adjusting at least one imaging related parameter (e.g., focus setting, exposure level, depth of focus in a plenoptic camera) of the device based on a region of interest (ROI) corresponding to the highest priority recognized face, and capturing an image.

主权项

1. An electronic apparatus comprising:
an image sensor configured to capture an image including a plurality of persons; a memory including data representing a ranked reference set of faces; a processor, coupled to the memory and to the image sensor, configured to:
receive image data from the image sensor;detect at least one face image in the image data;perform facial recognition on the at least one face image;in a case that a plurality of face images are detected in the image data and recognized as matching respective faces of the ranked reference set of faces,
select, as a designated face, a particular face image from the plurality of face images detected in the image data that corresponds to a highest ranked face in the ranked reference set of faces for a person of the plurality of persons,detect imaging conditions for a plurality of image regions in the image data,identify, as a region of interest, from the plurality of image regions in the image data, a particular image region that includes the designated face, andautomatically set at least one configuration parameter of the electronic apparatus based on the detected imaging conditions for at least the region of interest such as to prioritize the image quality of the designated face within a captured image of the plurality of persons that is captured using the electronic apparatus according to the automatically set at least one configuration parameter.
