Description

technical field [0001] The present invention relates to a display control device, a display device and a display method, in particular to a display control device, a display device and a display method capable of displaying individual images for multiple viewing directions on the same screen. Background technique [0002] In recent years, display devices such as televisions have been widely used not only at home but also as in-vehicle devices for outputting and displaying images and images to vehicle occupants. The vehicle-mounted display device was originally used to display route guidance to one's own vehicle, but in recent years, in addition to the use of route guidance, the vehicle-mounted display device has also been used as, for example, Patent Document 1 (Japanese Patent Laid-Open Publication No. 2003-244591 Publication) The display device disclosed in the vehicle-mounted television device, audio device, DVD playback device, etc. [0003] The uses of such in-vehicle ...

Problems solved by technology

[0013] In the case of displaying different images in multiple directions on one screen, it is conceivable that there will be a situation where it is necessary to simultaneously display an image with low resolution and an image that requires high resolution. However, Patent Documents 3 and 6 describe The device is to display the image for any direction with the same resolution, so there is a technical problem that the display resolution of a specific image cannot be improved, but the image can only be displayed at a resolution that cannot meet the user's requirements.

In addition, similarly, in the two-view display disclosed in Patent Document 5, since the display elements on the display are divided into the driver's seat side and the passenger's seat side for display, there is usually a reduction in the resolution of the display for each view. For half of such technical issues

In addition, the same technical problem will also occur in display devices for other purposes such as home use
