Abstract
The present disclosure relates to a method and a device for capturing an image and a computer readable storage medium. In the method, a current motion parameter of the terminal and a current ambient light parameter are acquired, a current exposure parameter of the terminal is set based on the current motion parameter of the terminal and the current ambient light parameter, and the image is captured based on the set current exposure parameter of the terminal. The exposure parameter includes a shutter value, an aperture value and a sensitivity.
