This invention discloses an image post process device and a method, in which, when this invention is going to amplify the being amplified image data, it first of all processes the image data particularly then to amply the size of the image data processed particularly, when it wants to reduce the image data, it first of all reduces the size of the data then to be processed particularly, when it amplifies the image, it selects the output zoom unit to be processed particularly then the amplified image data are output, when reducing the images, it selects the output particular processed units to be reduced then to be processed particularly and output, which can control the power loss for post process to images to the lowest and increase the speed of post process. |
