Abstract
A moving image coding apparatus includes a coding section, an intraframe filter circuit, and a selector. The coding section predicts a pixel block in a current frame from a preceding frame by a motion compensation scheme, and performs orthogonal transformation and quantization for a predicted error, thereby coding the predicted error. The intraframe filter circuit performs intraframe filtering for each pixel of an input frame. The selector adaptively determines and sets the filter characteristic of the intraframe filter circuit on the basis of a pixel of the input frame and a corresponding pixel of a predicted image or adaptively selects an output from the intraframe filter circuit having an optimal filter characteristic.
