1. An image encoding device that encodes an image, the image encoding device comprising:
a processor; and
a non-transitory memory having stored thereon executable instructions, which cause the processor to:
generate a predictive image on a predictive unit for a current coding unit using predictive information, the prediction unit being included in the coding unit,
wherein in a first mode, the processor generates a coefficient code string based on a residual coefficient, the residual coefficient being generated by performing an orthogonal transformation process and a quantizing process on a differential image between the image to be encoded and the generated predictive image,
wherein in a second mode, the processor directly uses the differential image to generate the coefficient code string without performing the orthogonal transformation process and the quantizing process, and
wherein a syntax of the current coding unit includes flag information indicating whether the first mode or the second mode is applied for the current coding unit and the syntax is included in a syntax of the coding unit separate from a syntax of the prediction unit included in the syntax of the coding unit.
