Image output method to displays with different aspect ratios
View Patent ↗First and second division patterns are defined so that main areas A and A′ are similar to each other in shape, having the same horizontal-to-vertical ratio. Even if an image output apparatus is connected to a display unit having both first and second display screens, the image output apparatus generates an identical image for the main area A or A′ regardless of the aspect ratio of the display screen. The main areas A and A′ display important information and the like. Sub areas B and B′ display auxiliary information. The first and second division patterns may be determined so that the sub areas B and B′ are similar to each other in shape like the main areas.
1. An image output method for first and second display screens having different aspect ratios, comprising:
when outputting to the first display screen, dividing the first display screen into a main area and a sub area based on a first division pattern; and generating images for each of the respective areas and outputting the images to the first display screen; and when outputting to the second display screen, dividing the second display screen into a main area and a sub area based on a second division pattern, and generating images for each of the respective areas and outputting the images to the second display screen, wherein
the first and second division patterns are defined so that the main area obtained by dividing the first display screen and the main area obtained by dividing the second display screen are similar to each other in shape.
2. The image output method according to claim 1 , wherein identical images are output to the main areas obtained by dividing the first and second display screens.
3. The image output method according to claim 1 , wherein the first and second division patterns are further defined so that the sub area obtained by dividing the first display screen and the sub area obtained by dividing the second display screen are similar to each other in shape.
4. The image output method according to claim 3 , wherein:
the first display screen and the second display screen have aspect ratios of 16:9 and 16:12, respectively;
the first division pattern is defined to divide the first display screen in approximately 1.26:14.74 horizontally; and
the second division pattern is defined to divide the second display screen in approximately 9.77:2.23 vertically.
5. The image output method according to claim 3 , wherein images rotated by 90° are output to the sub areas obtained by dividing the first and second display screens, respectively, in accordance with their respective horizontal-to-vertical ratios.
6. The image output method according to claim 1 , wherein images having the same meaning are output to the sub area obtained by dividing the first display screen and the sub area obtained by dividing the second display screen, respectively.
7. The image output method according to claim 1 , wherein image information is output to the main area obtained by dividing the first or second display screen, and text information is output to the sub area obtained by dividing the first or second display screen.
8. The image output method according to claim 1 , wherein:
the sub area obtained by dividing the first display screen and the sub area obtained by dividing the second display screen are further divided into the same numbers of divided areas, respectively; and
the divided areas of the first and second display screens are associated with each other, respectively, and images having the same meaning are output to the associated divided areas of the first and second display screens.
9. The image output method according to claim 8 , wherein at least one pair of associated divided areas of the first and second display screens are similar to each other in shape and have the same horizontal-to-vertical ratios, and identical images are output to the respective divided areas.
