An image decoding device 200 includes: a local addition unit 104a that adds level values of decoded residual coefficients existing around a residual coefficient to be decoded and derives a sum total value of level; a transform unit 104b that transforms the sum total value of level into an amount of shift and an index; a table reference unit 104c that refers to a predefined table and outputs a pre-correction Rice parameter corresponding to the index; and a correction unit 104d that derives a post-correction Rice parameter on the basis of the pre-correction Rice parameter and the amount of shift.
