B. Summary of the Invention The present invention provides an image display device in which the color information and/or shape information of cursor data is sequentially changed at a predetermined period of time and is synthesized on the input image signal. Cursor data can be clearly displayed even when a background color or background shape is included.

C. Conventional technology Traditionally, in news programs, in addition to videos of newscasters and commentators taken with TV cameras, and videos of crime scenes recorded with video tape recorders (VTR), photographs and commentary corresponding to the news are shown. Still images are sent out on boards, etc., so that viewers can easily understand the news content.

A so-called still image file device has been proposed for creating still images, filing them, reading them out at a predetermined timing, and sending them out (Japanese Patent Applications No. 1-108760 and 1-108761).

In practice, in this still image file device, when a person in charge of creating images creates still image data to be filed, first, still image information such as a photograph is photographed with a television camera.

The video signal obtained as a result is displayed on the screen of an image display device configured with a cathode ray tube (CRT), and the person in charge of drawing cuts out one desired frame of this video signal, and as a result, the result is shown in FIG. ), the still image PIC for one frame is displayed on the screen DSPO of the image display device.

Next, if the person in charge of drawing designates a rectangular cursor frame at a predetermined position and size by inputting coordinates from a keyboard, etc., the cursor frame KSW corresponding to the specified input will be displayed on the screen D.
It is displayed superimposed on the still image PIC of SPO.

After confirming that the cursor frame KSW is in the desired position and shape, the person in charge of drawing can then issue a reduction instruction from the keyboard, etc., as shown in FIG. 4(B).
Still images 5 PIC are reduced and displayed within the cursor frame KSW.

Furthermore, if the person in charge of drawing inputs text data such as an explanation using the keyboard at the bottom of the cursor frame KSW where the still image 5 PIC is displayed, the desired text data will be displayed below the cursor frame KSW in addition to the still image 5 PIC in the cursor frame KSW. DTM is displayed, and in this way desired still image data can be created.

The still image data created in this way is filed in a large capacity storage device such as a magneto-optical disk device, and as a result, a still image file is formed on the magneto-optical disk.

D Problems to be Solved by the Invention By the way, in the image display device of the still image file device having the above configuration, the cursor frame KSW displayed overlapping the still image PIC on the screen DSPO has a fixed display color in the image display device. In addition, predetermined display colors are used depending on the purpose.

However, the cursor frame KS consisting of such a single display color
In W, the cursor frame K changes depending on the background color on the screen DSPO.
There is a problem in that the visibility of the SW itself is significantly deteriorated.

Therefore, depending on the background color on the screen DSPO, for example, when the background color is black, the cursor frame KSW is displayed in white, and conversely, when the background color is white, the cursor frame KSW is displayed in black. equipment is used.

However, even with this method, still image PI is displayed on the screen DSPO.
In the case of displaying C, various color information is mixed as a background color, and therefore it is still insufficient in practical terms to improve the visibility of the cursor frame KSW.

Furthermore, as shown in Fig. 5, a similar problem occurs when a cross-shaped cursor KS is displayed on a grid-like background shape MX displayed on the screen DSPI. Therefore, even if the display shape of the cursor KS is changed to a circle or a square, when a still image PIC is displayed on the screen DSPl, various shapes may be mixed as background shapes, making it difficult to visually recognize the cursor KS. However, it was still insufficient for practical purposes to improve performance.

The present invention has been made in consideration of the above points, and aims to propose an image display device that can significantly improve the visibility of cursor data regardless of the background color and/or background shape on the screen. be.

E Means for Solving the Problems In order to solve the problems, the present invention includes a cursor data forming means 74 that generates cursor data DK having color information and shape information, and a cursor data forming means 74 that sequentially generates color information of the cursor data DK at a predetermined period of time. and/or cursor data changing means 74 and 75 for generating changed cursor data DG*s by changing shape information; and input image signal VDsy (DGos
ro) and the above-mentioned changed cursor data DGo to generate a composite image signal VD++sp (DGゎ, □), and the composite image signal V Dvsp
A display means 36 for displaying (D Gpsr+) is provided.

Changed cursor data DG*s obtained by sequentially changing the color information and/or shape information of the F-action cursor data DK at a predetermined period
is synthesized on the input image signal VDsy (D-Gospo), the input image signal VDsy (DC
+sp. ), even if the background contains various color information and shape information, the cursor data DK (KSW, KS)
