Abstract: The disclosure discloses a method for preprocessing an image and a related electronic device. A current data frame captured through a camera is obtained by a pre-created drawing surface window called by a central processing unit (CPU) in response to a preview activating instruction of the camera. The current data frame is converted into a preview texture corresponding to the current data frame by the pre-created drawing surface window. The preview texture corresponding to the current data frame is sent to a graphics processing unit (GPU). The preview texture corresponding to the current data frame is processed by the GPU. The preview texture processed is sent by the CPU to an advanced driving assistance system (ADAS).
