A picture coding device includes a motion prediction unit, an intra picture prediction unit, and an input selection unit. The input selection unit selects a smaller one of a motion total obtained by adding a motion residual and a value into which a motion vector is coded and an intra picture total obtained by adding an intra picture residual and a value into which a prediction mode is coded. The device further includes an I_PCM judgment unit comparing a cost with a first threshold value. Additionally, the device includes an output selection unit selecting coded data obtained by arithmetic coding as data to be outputted to the outside if the cost is equal to or less than the first threshold value and selecting I_PCM data as the data to be outputted to the outside if the cost is larger than the first threshold value.
