Image acquisition method and device and computer readable storage medium

The invention relates to an image acquisition method and device and a computer readable storage medium, and aims to ensure that light equipment with a bright-dark period is in a normal lightening state in an acquired image and avoid the problem that the light equipment is extinguished in the image. The method comprises the following steps: in response to a received image capture instruction, determining whether a lighting device with a bright-dark period exists in a to-be-shot object; if it is determined that the lighting device exists, the exposure time of an M channel of an image sensor is adjusted, so that the lighting device is in a lightened state in an image collected by a target channel of the image sensor, and the target channel is an S channel and/or an L channel; and when the light equipment is in a lightened state in the image acquired by the target channel of the image sensor, shooting the to-be-shot object to obtain a shot image. 本公开涉及一种图像获取方法、装置及计算机可读存储介质，以确保具有亮暗周期的灯光设备在所获取的图像中处于正常点亮状态，避免灯光设备在图像
