A method of displaying images in a display apparatus having a first display portion (201; 301; 502) and a second display portion (202; 303; 505), the method comprising: displaying a first image on the first display portion (201; 301; 502) of the display apparatus; displaying on the second display portion a user interface for receiving image-quality condition settings for setting the image-quality condition of the image displayed on the first display portion; receiving a first setting from the user interface for setting an image quality condition of the first image displayed on the first display portion (201; 301; 502) and a second setting from the user interface for setting an image quality condition of the first image displayed on the first display portion (201; 301; 502), the first setting and the second setting being different from each other; generating, via a first display controller of the first display portion, an image with the first-image quality condition by applying the first setting to the first image displayed on the first display portion and an image with the second image-quality condition by applying the second setting to the first image displayed on the first display portion; transmitting the generated image with the first-image quality condition and the generated image with the second image-quality condition from the first display controller of the first display portion to a second display controller of a second display portion (202; 303; 505); displaying the transmitted image with the first-image quality condition and the transmitted image with the second image-quality condition on the second display portion of the display apparatus, while displaying the first image on the first display portion without resizing; receiving a selection signal indicating a selection of one of the images with the first or second image-quality condition displayed on the second display portion (202; 303; 505); and setting the first image displayed on the first display portion (201; 301; 502), without interrupting the displaying of the first image, to have an image-quality condition corresponding to the selected first or second image-quality condition. displaying a first image on the first display portion (201; 301; 502) of the display apparatus; displaying on the second display portion a user interface for receiving image-quality condition settings for setting the image-quality condition of the image displayed on the first display portion; receiving a first setting from the user interface for setting an image quality condition of the first image displayed on the first display portion (201; 301; 502) and a second setting from the user interface for setting an image quality condition of the first image displayed on the first display portion (201; 301; 502), the first setting and the second setting being different from each other; generating, via a first display controller of the first display portion, an image with the first-image quality condition by applying the first setting to the first image displayed on the first display portion and an image with the second image-quality condition by applying the second setting to the first image displayed on the first display portion; transmitting the generated image with the first-image quality condition and the generated image with the second image-quality condition from the first display controller of the first display portion to a second display controller of a second display portion (202; 303; 505); displaying the transmitted image with the first-image quality condition and the transmitted image with the second image-quality condition on the second display portion of the display apparatus, while displaying the first image on the first display portion without resizing; receiving a selection signal indicating a selection of one of the images with the first or second image-quality condition displayed on the second display portion (202; 303; 505); and setting the first image displayed on the first display portion (201; 301; 502), without interrupting the displaying of the first image, to have an image-quality condition corresponding to the selected first or second image-quality condition.
