System and method for determining image resolution

摘要

Systems and methods for deductively determining a resolution setting for an imaging device based on one or more features of a scene are disclosed. The features may include the size of primary or foreground faces within the scene, a maximum amount of high frequency content within the scene, a lighting condition of the scene, or a battery level of an electronic device.

主权项

1. A system for determining an image capture resolution, comprising:
a processor configured to
operate an imaging device to obtain an image of a scene in a preview mode at a default image capture resolution;determine sizes of one or more regions of interest in the image of the scene;determine a scene-dependent resolution setting based on the determined sizes, the scene-dependent resolution setting being higher or lower than the default resolution, wherein the scene-dependent resolution setting is:
higher than the default resolution if a pixel area of a foreground region of the one or more regions of interest is less than a percentage of a field of view of the imaging device, andlower than the default resolution if the pixel area of the foreground region is not less than the percentage of the field of view of the imaging device;adjust the image capture resolution for the imaging device to the scene-dependent resolution setting; andobtain an image of the scene at the scene-dependent resolution setting.
