Image acquisition method and device

The invention relates to the technical field of images, and discloses an image acquisition method and device. The image acquisition method comprises the following steps that the same area on an image acquisition interface screen receives a touch motion; whether the first duration of the touch motion is the same as or longer than a preset first preparation time or not is judged; if the first duration is the same as or larger than the first preparation time, a timekeeping prompt message is displayed, and whether the second duration of the touch motion is the same as or larger than a preset second preparation time or not is judged; if the second duration is the same as or larger than the second preparation time, and corresponding images are acquired periodically according to the preset time interval. According to the image acquisition method and device, the setting process of continuous shooting operation is simplified, a quicker continuous shooting mode is provided, operation accuracy is improved, and the application range of touch screen shooting is broadened.
