FIELD: computer equipment.
SUBSTANCE: invention relates to the computer equipment. Image processing apparatus includes an installation module configured to arrange the depth value of the residual data bits of the color difference component and the depth value of the bits of the residual data of the luminance component so that they are uniform in the case where the depth value of the residual data bits of the color difference component of the image and the depth value of the residual data bits the components of the brightness of the image are different from each other; residual prediction module configured to predict the residual data of the color difference component in accordance with the bit depth value set by the setting unit by using residual luminance component data and with the possibility of generating the predicted residual data; and encoding unit configured to encode the predicted residual data generated by the residual prediction module.
EFFECT: prevented reduction of coding efficiency.
