Description

  The present invention relates to a video selection / playback system for displaying video data on display screens having different aspect ratios, and in particular, the video displayed when the display screen is switched between portrait orientation and landscape orientation. Visual effect is achieved by displaying different video data with different aspect ratios on the display screen when the display screen is in portrait and landscape orientations, while the data is always switched in a direction that is easy for the viewer to see according to the installation direction. The present invention relates to a video selection / playback system that can enhance the image quality.

  Conventionally, in order to give the game a story, to enhance the sense of reality and to enhance the fun, the technology that plays the video that reflects the story during the game has been developed, and various display methods have been devised. Technology is being developed and used. In particular, when enjoying a game using a portable type device such as a smartphone, a tablet terminal, or a portable game machine, it is required to play a video with the highest interest effect on a screen with a small display area. Development of technology for displaying images with various tastes is in progress.

  For example, there is a technique disclosed in Japanese Patent Application Laid-Open No. 2012-16616 as a technique that makes a video image in a game elaborate. Here, regarding a game operated by a game machine having a plurality of screens, when the two-dimensional coordinates of a specific object among the objects positioned by the two-dimensional coordinates satisfy a predetermined condition, the two-dimensional coordinates of each object are used. A technique is disclosed in which a three-dimensional coordinate of each object is calculated to model the object, and an image operated by a predetermined animation is displayed on a game screen. As a result, it is possible to provide a realistic video that is linked to the movement of the user.

  However, according to the above technique, it is considered that it is possible to enhance the interest of the game, but it is not possible to express the sense of reality during the game and to express the story of the game. In addition, there is no added device to enhance the game's interest, such as showing the part that could not be seen by rotating the screen using the characteristics of the screen with different aspect ratios. However, there is a problem that it cannot be said that the interest effect of the user is necessarily increased.

  In Japanese Patent Laid-Open No. 2005-204762, a display screen for two screens including a first display screen and a second display screen is provided, and one of the courses, items, enemy characters, and player characters is displayed on one display screen. On the other display screen, a technique for displaying one of a course, an item, and an enemy character is disclosed. Here, when the player character moves to the other display screen, the display type of one display screen and the other display screen is switched, and the display screen without the player character is another type of course or item that is not displayed. It is suggested that this can stimulate the player's curiosity.

  However, it is thought that this technology can stimulate the curiosity of the user, but since two images are always displayed, the effect of enhancing the interest like discovery by switching images is not necessarily exhibited. I couldn't say that. In addition, it does not use the effect of utilizing the screen characteristics with different aspect ratios, and it cannot be said that it is sufficient to enhance the interest effect of the user.

Therefore, by displaying separate video data with different aspect ratios in the vertical and horizontal directions and changing the vertical and horizontal display, the information that could not be recognized on one screen is visualized by switching the image, and the video enhances the interest effect Development of a selective reproduction system has been desired.
