According to one embodiment, a moving image encoding method is disclosed. The method can generate a prediction error image based on a difference between an input moving image and a predicted image. The method can execute transform and quantization on the prediction error image to generate quantized transformation coefficients. The method can generate edge information which indicates an attribute of an edge in a local decoded image corresponding to an encoded image. The method can generate, based on the edge information, control information associated with application of a filter to a decoded image at a decoding side. The method can set filter coefficients for the filter based on the control information. In addition, the method can encode the quantized transformation coefficients and filter coefficient information indicating the filter coefficients to output encoded data.
