An image transmission apparatus has a difference calculator configured to calculate a difference between actual image data and current predicted data based on previous data, a quantizer configured to generate quantized difference data obtained by quantizing the difference, a quantization characteristic determinator configured to determine a quantization characteristic corresponding to the quantizer based on pixel values of a plurality of neighbor pixels located in surroundings of a current pixel, and a encoder configured to generate code word to be transmitted via a least single transmission line based on the quantized difference data.
