<p>Disclosed is a moving image coding device which is provided with a coding control unit (113), a loop filter processing unit (107), an interpolation filter processing unit (110), a prediction image generation unit (111), a conversion unit (102), a quantization unit (103), and a coding unit (112). The coding control unit (113) obtains loop filter information, which is control information for performing a filter process of a local decoding image signal which indicates an image signal decoded for each pixel in the unit of process block. The loop filter processing unit (107) performs the filter process of the local decoding image signal on the basis of the loop filter information, to obtain a reproduction image signal. The interpolation filter processing unit (110) calculates, by using only an integer pixel, a pixel value of a decimal pixel, which is shifted by a 1/4 pixel in a horizontal direction or a vertical direction from the integer pixel of an image represented by the reproduction image signal, to obtain a reference image including the integer pixel and the decimal pixel. The prediction image generation unit (111) makes a motion compensating prediction with respect to the reference image, to generate a prediction image signal. The conversion unit (102) converts a residual signal which indicates a difference between an input image signal, which is an image signal inputted, and the prediction image signal, to obtain conversion coefficient information. The quantization unit (103) quantizes the conversion coefficient information, to obtain quantization conversion coefficient information. The coding unit (112) codes the quantization conversion coefficient information and the loop filter information.</p> |
