Abstract

PURPOSE:To satisfy a desire for drawing and coloring a picture by displaying an image drawn on a magnetic picture plate on a CRT screen by an image conversion device and displaying a specified color on a position of the CRT screen correspondingly to the magnetic picture plate by means of a specified color display device. CONSTITUTION:When an image is displayed on a surface board 5 of the magnetic picture plate 2 by a magnetic pen 1, the image is immediately displayed on the CRT screen 3a by an image converter 3. When a position on the magnetic picture plate 2 is touched with the magnetic pen 1 while depressing any one of color specification buttons 10, a line with the color specified by the color specification button 10 appears on the corresponding position on the CRT screen 3a. Consequently, the desire for drawing and coloring a picture can be satisfied, and hands, cloth or the like are not dirtied at the time of coloring.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention converts an image drawn on a magnetic drawing board onto a CRT screen, and also converts an image drawn on a magnetic drawing board to a position on the CRT screen corresponding to a predetermined position on the drawing board. This invention relates to image conversion from a magnetic drawing board to a CRT screen and a color display device that can display colors of ψ.

(Prior Art) Drawing is an almost instinctive desire for children, and magnetic drawing boards are known as a solution to this desire. This involves defining a number of honeycomb-shaped chambers between a translucent top plate and a back plate on the back side, each room containing magnetized black powder, and a magnetic pen placed on the top plate. When brought into contact, the suction force causes the black powder to float near the surface plate, thereby expressing images such as pictures and letters. When erasing an image, the black powder floated by the erasing plate may be caused to settle onto the back plate using magnetic repulsion.

As described above, the magnetic drawing board has the convenience of allowing images to be easily drawn and erased, but the disadvantage is that the images that appear on the magnetic drawing board are only black and white and cannot be colored in one color.

(Technical Problems of the Invention) The present invention has been developed in view of the above circumstances, and in particular, a magnetic drawing board capable of displaying an image on a magnetic drawing board on a CRT screen and also displaying colors on a CRT screen. The technical problem is to provide an image conversion and color display device for CRT screens.

(Means for Solving the Problems) In order to solve the above problems, from the magnetic drawing board according to the present invention
The image conversion and color display device for the RT screen consists of a magnetic drawing board on which images such as characters and figures are drawn with a magnetic pen, an image conversion device that electrically reads out the image on the magnetic drawing board and displays it on the CRT screen, and a magnetic drawing board. The present invention is characterized by comprising a specified color display device that displays a specified color at a corresponding position on a CRT screen in accordance with a color specified at one position on a drawing board.

(Operations and Effects of the Invention) As described above, according to the present invention, an image on a magnetic drawing board is displayed on a CRT screen by an image conversion device, and an image on a CRT screen corresponding to the magnetic drawing board is displayed by a specified color display device. Since the specified color can be displayed at a certain position, the user's desire to draw or color can be satisfied, and the user does not get his or her hands or clothes dirty while coloring. Therefore, it is possible to play an interesting game that has never been seen before.

(Example) Hereinafter, an example according to the present invention will be described with reference to the drawings.

In the figure, the symbol A indicates an image conversion and color display device from a magnetic drawing board to a CRT screen. an image conversion device 3 that reads out the image and displays it on the CR7 screen 3a; and a specified color display device 4 that displays the specified color at a corresponding position on the CR7 screen 3a in accordance with a color specified at one position on the magnetic drawing board 2.
It is composed of.

As shown in FIG. 1(b), the magnetic drawing board 2 defines a large number of honeycomb-shaped chambers 7 between a translucent front panel 5 and a back panel 6 on the back side thereof, and each chamber 7 is magnetized. By placing black powder 8 in the container and bringing the magnetic pen l into contact with the surface plate, the black powder is floated near the surface plate 5 by its suction force, thereby expressing images such as pictures, letters, etc. Furthermore, the powder is caused to settle by an erasing plate 1a having an opposite polarity.

According to the above configuration, an image is displayed on the surface plate 5 of the magnetic drawing board 2 depending on whether the powder of each part N7, 7φ, etc. sinks or floats, which means that electrically it is 1. Since it can be represented by the number 0, by placing a reader 9 on the back side of the back board 6 to read whether each room is 1 or 0, the image on the magnetic screen 2 can be replaced electrically. can do.

The image conversion device electrically reads out the image on the surface plate 5 of the magnetic drawing board 2 based on the 1.0 signal from the reading device 9, and displays an image corresponding to the above image on the CR7 screen 3a. .

Next, the color designation display device displays the color designation buttons 10, 10Φ, etc. provided on the magnetic board 2, such as red, blue, green, yen, etc. By tracing the position of the above color selection button 10 with a magnetic pen,
．． A line having a color specified by 10... appears at the corresponding position on the CR7 screen 3a.

According to the above device configuration, when an image is displayed on the surface plate 5 of the magnetic drawing board 2 by the magnetic pen l, this image is immediately displayed on the CR7 screen 3a by the image conversion device 3, and the color specification button 10.10 By tracing a position on the magnetic drawing board with a magnetic pen while pressing one of the @ buttons, a line with the color specified by the color specification button appears at the corresponding position on the CR7 screen 3a. Therefore, not only the desire to draw and color is satisfied, but also the coloring process does not stain hands or clothes. Therefore, it is possible to play an interesting game that has never been seen before.

As shown in FIG. 2, if the magnetic drawing board 2 is provided with a copying function, the colored image on the CR7 screen 3a can be transferred to
can be copied.

In addition, as shown in FIG. 3, the video captured by the black and white video camera 15 is recorded on the video cassette 16, and by setting this on the magnetic drawing board 2, the recorded video is projected on the CR7 screen 3a. Draw by tracing on the surface plate 5 of the screen with the magnetic pen 11 while viewing the image on the CR7 screen 3a. As a result, an image resembling the image on the CRT screen 3a can be drawn on the surface plate 5 of the magnetic drawing board. In this case, the image on the surface plate 5 of the magnetic drawing board 2 appears as a duplicate on the CR7 screen 3a by the image converter W13. Thereafter, in the same manner as in the example of FIG. 1, by tracing the surface plate 5 of the magnetic drawing board 2 with the magnetic pen 1 while pressing the color specification button 10.10-@, the color specification button 1O110... A line with the selected color appears at the corresponding position on the CR7 screen 3a. Therefore, in the case of a figure, colors can be applied to each of the hair, skin, mouth, and background.

Incidentally, the magnetic drawing board 2 may be provided with a copying function if necessary.
