The invention discloses a device and a method for amplifying image translation display. The device comprises a CPU, an LCD controller, an SDRAM controller, a band source destination windowing image scaler, an image scaler, an SDRAM and an LCD display screen. The invention also discloses the method for amplifying the image translation display, which comprises the following steps that: the CPU setsa source windowing address generator and a destination windowing address generator, starts the image scaler to implement scaling processing of images, writes the processed data into the SDRAM, and finally displays the data through an LCD display. The device and the method greatly reduce the read-write quantity of the data, save the bandwidth of the SDRAM, improve the display speed, and implement horizontal smooth movement of the amplified images, thereby achieving higher performance with lower cost.
