Projector, non-transitory medium, and image generation method

An image generation system comprising:

• a storage section that stores character string data that indicates a character string in at least one language and arrangement designation data that indicates whether the character string in the at least one language is displayed in a left-to-right direction or a right-to-left direction;
• a determination section that determines arrangement of the character string based on the arrangement designation data;
• and
• an image generation section that generates an on-screen display (OSD) image that shows the character string in the left-to-right direction or the right-to-left direction based on the character string data and the arrangement of the character string determined by the determination section,
• when the image generation section generates a special image that shows a special character string including at least one of alphanumeric characters and symbols as part of the OSD image, the image generation section generating the special image that displays the special character string in the left-to-right direction,
• the storage section storing coordination data that indicates an upper-left coordination position or an upper-right coordinate position of the character string in the at least one language;
• when the determination section has determined that the arrangement of the character string is the right-to-left direction, the image generation section drawing the character string from the upper-left coordinate position indicated by the coordinate data;
• when the determination section has determined that the arrangement of the character string is the right-to-left direction, the image generation section determining a total length of the character string based on the character string data, and drawing the character string from a coordinate position obtained by subtracting the total length from the upper-right coordinate position indicated by the coordinate data;
• the special image including an entry field for the special character string;
• the storage section storing maximum character count data that indicates the number of characters that can be input to the entry field;
• and
• when the determination section has determined that the arrangement of the character string is the right-to-left direction and the image generation section generates an image that shows an input character string input to the entry field, the image generation section calculating a subtractive value by subtracting the number of characters of the input character string from the number of characters that can be input to the entry field based on the maximum character count data, determining the total length by summing up the number of characters of the input character string, the subtractive value, and the number of characters of the character string displayed in the right-to-left direction based on the character string data, and drawing composite character string from a coordinate position obtained by subtracting the total length from the upper-right coordinate position indicated by the coordinate data, the composite character string being obtained by adding the character string displayed in the right-to-left direction after an additional character string obtained by adding a blank character string corresponding to the subtractive value to the input character string.
