<p>The present art relates to an image processing device and method which are capable of suppressing the increase of the amount of codes of a quantization matrix. An axis setting unit (151) sets reference axes including matrix elements to be transmitted, according to the type of a quantization matrix. For a vertical axis set by the axis setting unit (151), a vertical axis setting unit (152) to a diagonal axis setting unit (154) each select, as a reference matrix element, a quantization matrix element to be transmitted, according to a mode in which the quantization matrix element is to be transmitted. An interpolation processing unit (155) performs interpolation processing and sets an interpolated quantization matrix. A residual processing unit (157) sets a residual quantization matrix. A parameter generation unit (156) transmits, as parameters, the reference matrix elements set by the vertical axis setting unit (152) to the diagonal axis setting unit (154), the differences between matrix elements, and data generated by the residual processing unit. This disclosure is applicable, for example, to an image processing device.</p> |
