The invention provides an image processing method and a mobile terminal. The mobile terminal is provided with a flexible screen. The method comprises the steps of when a display screen of the mobile terminal displays a target image, detecting a bending operation of a user for the flexible screen; if the bending operation is detected, determining a to-be-processed target image area in the target image according to the bending operation; and encrypting the target image area. In the prior art, when one picture has both to-be-checked information and private information, user privacy is easy to disclose. The imaging processing method and mobile terminal solve the problem in the prior art.
