Image capturing parameter adjustment in preview mode

摘要

A method, which is performed by an electronic device, for adjusting at least one image capturing parameter in a preview mode is disclosed. The method may include capturing a preview image of a scene including at least one text object based on a set of image capturing parameters. The method may also identify a plurality of text regions in the preview image. From the plurality of text regions, a target focus region may be selected. Based on the target focus region, the at least one image capturing parameter may be adjusted.

1. A method, performed by an electronic device with an image sensor, for capturing at least one image, the method comprising:
capturing a preview image of a scene including at least one text object; identifying a plurality of text regions in the preview image; selecting a target focus region from the plurality of text regions; determining at least one brightness value associated with the target focus region; comparing the at least one brightness value to a threshold value; and adjusting at least one image capturing parameter for the image sensor based on the comparison.
