Abstract: The disclosure discloses an image copying method, which includes the steps of: copying, an image to be copied, to a destination address line by line, in the case of the image to be copied having a width of one pixel; copying, the image to be copied, to the destination address by a number of bytes according to a size of the image to be copied, in the case of the image to be copied not having a width of one pixel. The image copying method can save the image copying time and deduce the Central Processing Unit (CPU) occupation rate.

Abstract translation: 本公开公开了一种图像复制方法，其包括以下步骤：在要复制的图像的情况下，将要复制的图像逐行地复制到目的地址，具有一个像素的宽度; 在要复制的图像不具有一个像素的宽度的情况下，根据要复制的图像的大小将要复制的图像复制到目的地地址多个字节。 图像复制方法可以节省图像复制时间，并推导出中央处理单元（CPU）占用率。
