ELECTRONIC DEVICE AND PHOTO CAPTURING METHOD

摘要

A photo capturing method includes recognizing a capturing target of a preview image of a camera device. A preview ratio of the preview image is obtained by calculating a ratio between an area of a smallest rectangle enclosing the capturing target in the preview image and an area of the preview image is calculated. A category that the preview image belongs to is determined according to the capturing target. An average ratio of the determined category is obtained. Once the preview ratio is not equal to the average ratio of the determined category, a capturing range of the camera device is adjusted.

1. A photo capturing method applied in an electronic device, the method comprising:
recognizing a capturing target of a preview image of a camera device of the electronic device; obtaining a preview ratio of the preview image by calculating a ratio between an area of a smallest rectangle enclosing the capturing target in the preview image and an area of the preview image; determining which category the preview image belongs to according to the capturing target and obtaining a determined category; obtaining an average ratio of the determined category; comparing the preview ratio and the average ratio; and adjusting a capturing range of the camera device when the preview ratio is not equal to the average ratio.
