PROBLEM TO BE SOLVED: To prevent the error diffusion effect from weakening, when the value of 0 or a value near 0 is outputted in a D/A converter.SOLUTION: A selection device comprises: an acquisition unit for acquiring a digital selection signal; and an output unit for outputting a selection signal to a plurality of unit cells, respectively. The selection signal instructs the unit cell to output a value corresponding to the selection signal. The total of the values instructed to be outputted by the selection signals outputted to the plurality of unit cells depends on the digital selection signal. If the output corresponding to the digital selection signal has a value 0, there is a unit cell to which a selection signal for instructing to output a value N not 0 is outputted. |
