Abstract

An image processor includes a quantization unit receiving first data before quantization and outputting second data after quantization, a prediction unit obtaining a difference value between the second data and third data being prediction data and outputting the difference value as fourth data, and an encoding unit encoding the fourth data. The quantization unit includes a first processing unit dividing the first data by a quantization coefficient, so as to obtain fifth data including a fraction as a result of division and a second processing unit rounding up or rounding off the fraction such that a value of the fourth data becomes smaller based on comparison between the third data and the fifth data, so as to obtain the second data.
