JPS6267978A - Controller for superimpose display position - Google Patents

Abstract

PURPOSE:To prevent an omission of the information by storing the existence of a displaying subordinate picture, an illustration and characters and a displaying position of the subordinate picture and automatically changing the displaying position of the subordinate picture when both the display information overlaps. CONSTITUTION:A subordinate picture/character display control part 6 is ordinarily constituted by a microcomputer. The control part 6 has a display memory part 6a and a display position control part 6b. In the memory part 6a, the information of the existance of displaying of a subordinate picture and a picture and character and a subordinate picture display position are numerically stored. When both the subordinate picture and the picture and character display are superimposed, the display position is decided by using an arithmetic function of the microcomputer and when both the positions are superimposed, a new display position is instructed to a subordinate picture control part 2.

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.

2. Description of the Related Art In recent years, television receivers have been used to display reduced child images on the same screen as the parent image, pictures of channel numbers, etc.
A function to superimpose text information has been added. The double superimposition method will be explained below with reference to the drawings.

FIG. 3 shows a conventional superimposition method. In FIG. 3, the child image signal reduced by the child image control unit 2 is superimposed on the parent image by the signal switch 1 after the child image display position control unit 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 switching device 1 on which the child image is superimposed is superimposed with the display characters generated from the display character generating section 7 by the signal switching device 3, and the output is superimposed with the display characters generated from the display character generating section 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, in the method described in -, when the positions of the child image and the displayed character match, the child image is cut out by the displayed character. The problem was that information was missing.

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 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 when the display positions overlap, the display positions of the child images are automatically changed according to a programmed procedure.

Function: 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.

EXAMPLE An example 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.

The operations of the signal switch 1, child image control section 2, and signal switch 3 are the same as those in the conventional embodiment, and therefore will not be described here. 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 side (property) section 6b.
, the information on whether the child image and pictorial/character display are being displayed and the child image display position are stored in numerical form. Child images and drawings/
When both character displays are superimposed, the display position is determined using the arithmetic function of the microcomputer, and when the positions of both overlap, the child image control unit 2
711. to specify the new display position. FIG. 2 is a flowchart showing the process for displaying the picture/character display position at the bottom of the screen.

FIG. 2(a) shows Flow 5 when there is a picture/character display input.

In this case, it is determined whether or not a child image is being displayed, and if it is being displayed, its display position is determined, and if it is located at the bottom of the screen, the child image is displayed. Move to the top of the screen and memorize its position. FIG. 2(b) is the flowchart 1 when there is a child image input/position movement input. Determines the display position specification input, and if the lower side is specified, controls the child image to be moved to the upper side, and if the moat child image position specification input is upper side, displays the child image at the specified position, Furthermore, the display position is memorized.

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.
