摘要： A driving device for driving an image display system, which sequentially receives input image data corresponding to gradation of each pixel of a display image and outputs a driving voltage signal includes: an operation section for obtaining output image data of which a bit number is smaller than a bit number of the input image data based on input image data of a target pixel to be processed and input image data of a pixel in vicinity of the target pixel; a reference voltage generation section for generating a plurality of reference voltages of different levels; and a reference voltage selection section for selecting one of the plurality of reference voltages. The operation section is configured to obtain output image data of the target pixel so that a difference between the input image data and output image data of the target pixel and a difference between the input image data and output image data of the pixel in vicinity of the target pixel cancel out each other.
