ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a vide appliance suitable for use in a case where a picture screen is displayed with an arbitrary size at an arbitrary position on a display screen, for example, and in detail makes a figure to be displayed on the picture screen in a superimposed fashion easy to be seen always.
2. Description of the Related Art
In a video appliance such a television receiver for example, it is carried out that on a display screen there are displayed a main picture screen as well as a sub-picture screen which is reduced in size. On the other hand, in such a video appliance, it has been carried out that a character or a figure indicating a reception channel or the like is displayed on the picture screen displayed on the display screen in a superimposed fashion (on screen display which is simply referred to as OSD). Thus, there occurs such a case that the picture screen, in which the superimposing display is carried out, is reduced in size and then displayed as the sub-picture screen described above.
By the way, such a figure displayed in a superimposed fashion is generally made small so as not to be become an obstacle to the picture screen. If such a small figure is reduced further, there is such a fear that this figure is difficult to be recognized visually.
Namely, as shown in
FIG. 4A
, for example, when the “OSD” of superimposing display having a size, which does not become an obstacle in a main screen, is reduced into a sub-picture screen, the “OSD” becomes very small and is difficult to be visually recognized. On the contrary, when as shown in
FIG. 4B
, the “OSD” is made as a large figure to be visually recognized even in the sub-picture screen, if this picture screen is made as a main picture screen, the large figure becomes an obstacle to the picture screen.
SUMMARY OF THE INVENTION
In view of the above point, an object of the present invention is to reduce or expand a figure to be displayed in a superimposing fashion in correspondence with expansion or reduction of a picture screen. Thus, the size of the figure to be displayed in a superimposing fashion is made substantially same in size even in a reduced picture screen, and hence the figure can be visually recognized with ease.
According to an aspect of the present invention, there is provided a video appliance in which a picture screen can be arbitrarily expanded or reduced on a display screen and displayed at an arbitrary position and which can reduce or expand a figure to be displayed in a superimposing manner in association with the picture screen in response to expansion or reduction of the picture screen.
