Description

[Detailed Description of the Invention] [Summary] The present invention provides an LUT memory type refresh type display device in which the blink period of display information is determined by the execution cycle of a display program or a predetermined period determination hardware such as an oscillator. In order to more universally improve the problem that the blinking time and color are determined by
The blink minor routine is made independent of the refresh program.

[Industrial application field]

The present invention relates to blink control of a display device.The blinking operation that changes the volatility and color of the 0 display in a certain period to make it stand out is useful for distinguishing specific display content from other display content on the same screen. It is increasingly being used in electronic display devices. The present invention describes improvements to that basic method.

[Conventional technology]

FIG. 3 shows the main part of color processing in a conventional LUT memory type display device.

Reference numeral 1 indicates a screen refresh memory consisting of a plurality of surfaces having display information (referred to as a color number) including brightness and color corresponding to the dots on the display screen, 2 an address circuit for reading out the memory, and 13 a wrapping corresponding to the three primary colors. LUT with data
(lookup table). The output of LUT is CR
Connected to the video signal generation circuit of the T display tube.

Conventionally, when blinking, an LU receives color information at a fixed cycle determined by a program from the CPU 10 etc. that controls the display.
The method used was to rewrite the T memory.

That is, the coordinates of the screen refresh memory 1 are read out in parallel, and the display information (color number) corresponding to the coordinates is read out in R.
This is the address of each LUT memory 13 that supports the three primary colors of GB, and the color code indicated by the LUT at the 1st address was sent to a CRT display tube section that does not record it as real color information. In the case of blinking, when the program came to the location designated by the printer, the CPU10 rewrote the LUT memo IJ13 to change the display color.

[Problem that the invention seeks to solve]

In the conventional method, the printer operation is determined in the display program of the CPU that controls the display, and even if the operator wants to specify blinking during operation, it is extremely difficult to change it immediately. I want to draw the viewer's attention by blinking a specific figure or scene.

[Means for solving problems]

In the screen refresh memory readout section of the LUT memory format glue-fresh type display device shown in FIG. LUT-shaped message memory 6゛ that changes color by blinking from color, linked with reading of screen refresh memory 1,
A printer pattern memory 3 that can be changed and set from the outside, a lap counter 4 used to select the current pattern of the printer pattern (color state due to color switching of pixel display), and means for switching between two LUTs. A printer controller 5 having a multiplexer function is provided.

[For production]

The color number data read from the screen refresh memory l is passed through an appropriate delay circuit 7 to LUT6 and LU
The T-shaped memory 6' refers to the printed color table and prepares to output a color signal to the display section, and reads out the blink pattern corresponding to the dot from the blink pattern memory 3, and the blink controller 5 with a multiplexer function
For example, 1.0 in the horizontal direction of column #F in Figure 2 assigned to that color number (1 is blink color, 0 is normal color)
If a blink pattern as shown in is developed and the blink pattern is counted using the output of the lap counter 4 which determines the time on the horizontal axis of the pattern memory, it will indicate the current state to be displayed (for example, 1). Therefore, when the LUT 6 in this state is replaced by the LUT 6°, the blink color data that has been expanded and stored in the CPtJ in the LUT 6 is sent to the video signal generation circuit.

In this manner, the color impression of the video signal can be switched between the normal color and the blink color depending on the contents of the blink pattern memory 3.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to FIGS. 1 and 2.

In Figure 1, 1 is a screen refresh memory, 2 is an address circuit, 3 is a blink pattern memory, 4 is a circulation counter, 5 is a blink controller, 6 is an LUT that displays normal colors, and 6° is an LUT-like memory that displays blink colors. , 7 is a delay circuit.

FIG. 2 shows an example of the printer pattern memory 3, and takes the case where the screen refresh memory 1 is arranged in a vertical column and consists of four pages with N=3, and the color numbers that are display information are from #0 to #. Assuming that there are 16 possible combinations up to F, these combinations are written vertically. On the horizontal axis, the normal color is set to 0 and the blink color is set to l, and the time series state is written as 1.0.

Here, 16 blink states are written, but since the contents can be determined by the operator, this memory may be a memory representing at least two states or a memory representing eight states.

The present invention attempts to describe printer information of a color number corresponding to a read pixel with reference to FIG.

In FIG. 1, a screen refresh memory 1 corresponding to color and brightness information is scanned by an address circuit 2 to extract a color number corresponding to display coordinates, and then passed through a delay circuit 7 to compensate for delays in another route circuit, which will be described later. , LUT memory 6 and L
The color information is read out to the video signal by referring to the UT-shaped memory 6, and as mentioned above, the following elements 3, 4.5 are used.
The main points of the present invention will be developed through a different route consisting of: That is, the blink pattern memory 3 storing the blink pattern corresponding to the same color number as mentioned above is addressed from the screen refresh memory 1, and the pattern to be blinked with the color number is developed and stored in the printer controller 5 having a multiplexer function. . When the blink controller 5 with the multiplexer function is selected using the output of the circulation counter 4 which counts the blink pattern for each color number in units of vertical synchronization pulses, the blink information at the current time of the dot just taken out (0 normal If the output from the blink controller 5 is used to change the LUT 6 and the LUT-like memory 6, the current color data to be displayed will be displayed.

In this way, each dot forming the screen has a printer pattern for each color number written in the screen refresh memory l.

The blink color can be freely changed by changing the LUT-shaped message memory 6'' using the CPU I O, and the contents of the blink can also be freely changed using the blink pattern memory 3 using software or an input device such as a keyboard.

The diagram of the blink pattern memory shown in Figure 2 is just one example of the blink pattern as mentioned above, but only the color number to be blinked is written as 1.0, alternately for each single or multiple color number. be.

It may be possible to use a random number table or music rhythm information to determine the sequence of 1's and 0's that correspond to this blink pattern.

An additional feature is that since the blink controller 5 based on the vertical synchronization signal is used to switch the LUT, there is no noise when switching colors.

〔Effect of the invention〕

According to the present invention, the blinking operation can be performed pixel by pixel, and it is possible to blink between any used colors in any period that is a multiple of the reference unit time.

Therefore, for example, any figure that has a different color number on one display screen can be taken out and blinked to attract attention, and by using the present invention, all the displayed objects can be arbitrarily displayed. An unrealistic screen that blinks at different time intervals with different colors can be obtained by simply setting conditions.As mentioned above, the present invention makes the presentation free and easy for new displays. Therefore, it will have a great effect on future displays.
