Provided is an image processing device provided with: a prediction unit that, when performing intra-prediction that is on the basis of a dynamically constructed prediction function, in order to avoid or mitigate an increase in processing cost necessary to construct the prediction function, generates a predicted value for the chroma of a pixel of a decoded image using a function of the value of the corresponding luma; a coefficient calculation unit that calculates the coefficients of the function used by the prediction unit by referring to the neighboring pixels of the block to which the pixel belongs; and a control unit that controls the ratio of the number of reference pixels used by the coefficient calculation unit to the block size of the block. |
