• a processor;
• and
• a memory coupled to the processor to store instructions that, when executed by the processor, cause the processor to perform operations comprising:
• reading out a table indicating image quality adjusting parameters corresponding to a plurality of predetermined program genres;
• determining respective image qualities of the plurality of images based on a combination of program genre of the plurality of images displayed in the multi-display mode, so as to reduce a difference of image qualities between the plurality of images according to the combination of program genre of the plurality of images;
• and
• processing the plurality of image data to cause the plurality of images to have the determined respective image qualities,
• wherein an image quality adjusting parameter corresponding to a program genre of a sub image displayed in the multi-screen display mode differs dependent on a program genre of a main image combined with the sub image.
