1. A method of displaying an image comprising the steps of: storing a font of a language to be written from left to right in ROM for storing OSD-related data in an ordinary style in which the font is not reversed left to right, and storing a font of a language to be written from right to left in ROM for storing the OSD-related data in a style in which each ordinary font is reversed left to right, reading menu data, which are component data of a setup menu to be displayed on a screen, from said ROM for storing the OSD-related data and deploying the read data on RAM for a work area, reading frame data and icon data from said ROM for storing the OSD-related data according to said menu data deployed in said RAM for a work area, and deploying the read data in a memory section as OSD picture data, acquiring a selection language, which is a language to be displayed, reading text data of the acquired selection language from said ROM for storing the OSD-related data, selecting the font to be used from said text data, reading word data and font data from said ROM for storing the OSD-related data and deploying the read data in said memory section as said OSD picture data, deciding whether or not said selection language is a language to be written from right to left, if said selection language is a language to be written from right to left, then setting up information indicating reversion in a reversion selection register for selecting whether to reverse an OSD picture left to right, and if said selection language is a language to be written from left to right, then setting up information indicating no reversion in a reversion selection register, and If a setup value of said reversion selection register is the information indicating reversion, then reversing left to right said OSD picture stored in said memory section and transferring the reversed picture to VRAM.
