A releasing method of an image capturing module of an electronic device, including an electronic device, wherein the electronic device includes a first machine body and an image capturing module pivotally connected to the first machine body, and the image capturing module is restrained by the first machine body to approach to the first machine body. Performing a posture estimation procedure includes, sensing a first included angle between the first machine body and a gravity direction for determining whether the electronic device is in a tent position. When the electronic device is determined to be in the tent position, determine whether a release instruction is received, so as to decide whether to perform a release procedure, wherein when the release procedure is performed, the first machine body releases the image capturing module, so that the image capturing module is turned up relative to the first machine body.
