Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a superimposition display position control device that eliminates superimposition at the same position when a plurality of images are superimposed.

BACKGROUND OF THE INVENTION In recent years, television receivers have been equipped with a function to superimpose a reduced child image on the same screen as the parent image, as well as pictorial and textual information such as channel numbers and other operating conditions. The above superimposing method will be explained below with reference to the drawings.

FIG. 3 shows a conventional superimposition method. In FIG. 3, the child image control unit 2
The reduced-processed child image signal is superimposed on the parent image by the signal switching device 1 after the child image display position control section 4 specifies the display position on the screen. At this time, the parent image of the child image display portion is cut out. Further, the output of the signal switcher 1 on which the child image is superimposed is superimposed with the display characters generated from the display character generator 7 by the signal switcher 3, and the output is superimposed with the display characters generated from the display character generator 7. will be displayed. Display characters are stored in a character generation memory 8, and the type of character and display timing are controlled by a display character generation control section 5.

Problems to be Solved by the Invention However, the above method has a problem in that when the positions of the child image and the displayed character match, the child image is cut off by the displayed character, and the child image information is missing. Ta.

In view of the above problems, the present invention provides a superimpose display position control device that enables automatic change of the child image display position.

Means for Solving the Problems In order to achieve this object, the superimpose display position control device of the present invention stores information about whether a child image and pictures/characters are being displayed and the display position of the child image in a storage means of a microcomputer. The sub-images are stored in the sub-images, and if the display positions overlap, the display positions of the child images are automatically changed according to a programmed procedure.

Effect: With this configuration, when a child image and a pictorial/character display overlap, the child image is automatically moved, and the superimposed information of both can be displayed without missing.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a child image display position control device according to an embodiment of the present invention, and FIG. 2 shows a processing flow for automatically changing the display position.

Signal switch 1, child image control unit 2, signal switch 3
Since the operation is similar to that of the conventional embodiment, the explanation here will be omitted. The child image/character display control section 6 is usually composed of a microcomputer. The child image/character display control section 6 has a display storage section 6a and a display position control section 6b, and the display storage section 6a stores information on whether or not the child image and pictorial/character display are being displayed, and the child image display position. Convert it into numbers and memorize it. If both the child image and the picture/text display are superimposed,
The display position is determined using the arithmetic function of the microcomputer, and if the two positions overlap, a new display position is instructed to the child image control unit 2. FIG. 2 is a flowchart showing the process for displaying the picture/character display position at the bottom of the screen.

Figure 2a shows a flowchart when there is a picture/character display input. In this case, first it is determined whether a child image is being displayed, and if it is being displayed, its display position is determined. , if the child image is located at the bottom of the screen, the child image is moved to the top of the screen and its position is memorized. Figure 2b is a flowchart when there is a child image input/position movement input. First, it is determined whether or not characters/pictures are being displayed, and if characters are being displayed, the display position specification input of the child image is input. If the lower side is specified, the child image is controlled to be moved to the upper side, and if the child image position specification input is upper side, the child image is displayed at the specified position, and the display position is memorized. I try to do that.

Effects of the Invention As described above, according to the present invention, the presence or absence of a child image and pictures/characters being displayed and the display position of the child image are memorized, and when the display information of both sides overlaps, the display position of the child image is automatically changed. By changing this, both pieces of superimposed information can be easily displayed on the same screen without missing them.
