The present invention relates to the technical field of data processing. Disclosed are an image processing method and apparatus, and an electronic terminal, capable of improving the image quality of a static image after the static image is superposed with a dynamic image. The method in the embodiments of the present invention comprises: receiving an image superposition instruction, and acquiring a static image, a dynamic image, a data length of the dynamic image and a coordinates position of the dynamic image in the static image; and then generating, according to the image superposition instruction, target image data comprising the static image and the dynamic image. The present invention is applicable to an image processing flow.
