Next, the character / graphics drawing means 205 responds to the timing signal 212 sequentially output from the timing generating means 204, from the character / graphics data 209 and the character / graphics display parameter 211 to the character / graphics raster data 21.
3 is output. The display memory 206 stores the character / graphic raster data 213 and outputs a display signal 214. The display device 207 displays the display signal 214.

[0006]

However, in the conventional structure as described above, in order to create an image in which characters and figures move around randomly and change colors, the characters and figures displayed at each timing are changed. Since it is necessary to input all display parameters such as position and color, there is a problem that a large amount of work is required for creation.

In view of the above problems, it is an object of the present invention to provide an image display device capable of producing an image in which characters and figures move around randomly and change colors, with a small amount of work.

[0008]

[Means for Solving the Problems] To achieve the above object,
The image display device of the present invention includes a character / graphics input means for inputting character / graphics data, a character / graphics data storage means for storing the character / graphics data, a random number generation means for generating and outputting a random number, and a character / graphics from the random numbers. A character and graphic display parameter output means for calculating and outputting a character and graphic display parameter which is an attribute for displaying, a timing generating means for generating a timing signal for sequentially generating an image, and a response to the timing signal, A character and graphic drawing means for generating character and graphic raster data from the character and graphic data and the character and graphic display parameter, a display memory for storing the character and graphic raster data and outputting a display signal, and a display device for outputting the display signal to a screen. It is a configuration provided with.

[0009]

According to the present invention, the random number generating means having the above-mentioned configuration generates a random number, and the character / graphic display parameter output means calculates the character / graphic display parameter which is an attribute for displaying a character / graphic from the random number. Therefore, it is not necessary to input all the display parameters, the amount of work is small, and it is possible to create an image in which characters and figures move around randomly and change colors.

For example, when calculating the display parameter of the display position, convert the numerical value so that it is within the range of horizontal and vertical pixel numbers of the screen,
When calculating the display parameter of the display color, the value is R
Numerical values are converted so as to fall within the range of GB values, and are output as the character / graphic display parameter 112.

The timing generating means 105 sequentially outputs the timing signal 113 at the time when the movement of the character or the graphic is set. For example, set the movement of characters and figures for N seconds,
When generating the video of the TSC signal, N × 30 timing signals 113 are output. Character / figure drawing means 106
Generates the character / graphics raster data 114 from the character / graphics data 110 and the character / graphics display parameter 112 in response to the timing signal 113. Display memory 107
Stores the character / graphics raster data 114 and D
The display signal 115 that has been A / A converted is output. Display device 10
8 displays the display signal 115 on a CRT or a liquid crystal display.

As described above, according to the present embodiment, the random number generating means 103 generates the random number 111, and the character / graphic display parameter output means 104 uses the random number 111 to display the character / graphic which is an attribute for displaying the character / graphic. Parameter 112
Since it is possible to calculate, it is not necessary to input all the display parameters, the amount of work is small, and it is possible to create an image in which characters and figures move randomly and colors are changed.
