The invention is applicable to the field of picture processing and provides an image processing method, an image processing device and a terminal. The method comprises the steps of receiving an operating instruction made by a user to multimedia photographing application of the terminal, making a response to the operating instruction, using a photographing unit of the terminal to take a picture and presetting an area superposed with time information on a photographing interface, wherein the time information is information of a time period from a first time point to a second time point; using a time information acquisition unit of the terminal to acquire the time information; detecting a superposition instruction input by the user, making a response to the superposition instruction and superposing the acquired time information onto the area which is preset in the photographing interface; and detecting a photographing instruction input by the user, making a response to the photographing instruction and outputting a photographed image superposed with the time information. The image processing method, the image processing device and the terminal provided by the embodiment of the invention have the advantage that the images photographed by using the terminal can display diversified information by superposing the time information onto the photographing interface of the terminal.
