To allow image processing fit to an environment in a used area, without conducting a setting operation for the image processing by a user.

A signal processing circuit 17 conducts the image processing, using a parameter corresponding to a set language data out of the parameters (for example, color conversion factor, convergence point of color balance, gamma conversion coefficient, and an edge intensifying factor), different each other, corresponding to the plurality of language data, by perceiving that the language data are set to be fit to the used areas.
