Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a display control device characterized by a schedule management method, and more particularly to a control technology for displaying various advertisements one after another on a public display device in which lamps such as high-intensity LEDs (light emitting diodes) are arranged in a matrix. .
[0002]
[Prior art]
In the present application, the following scroll display system disclosed in detail in Japanese Patent Laid-Open No. 8-179717 has been developed and put into practical use. This is a scroll display technology in which a small and fine image can be visually recognized with a small number of light emitting elements (such as LED lamps). The most distinctive feature is that a fine image interpolated by the afterimage effect can be visually recognized only after the scrolling image is traced with a line of sight. This mechanism is named the tracking interpolation scroll display.
In this tracking interpolation type scroll display system, a large number of LED lamps are linearly arranged at a small constant interval d1 to form a lamp row, and a large number of the lamp rows are prepared and a large constant interval of at least an integer multiple of d1. They are arranged in parallel at d2. Then, image data in a bit map format corresponding to each element of the lamp row is prepared for one dot configuration, and the data of each row of the image is supplied to each lamp row in order and displayed. At the same time, the following temporal control is performed.
The number assigned to the lamp rows in the order of arrangement is i, the number assigned to each row data of the image data is j, and an integer of 2 or more appropriately set corresponding to the interval d2 is a. And Then, when the lamp row of the i-th column is displayed and driven by the column data of the j-th column, the lamp column of the (i + 1) -th column is displayed and driven by the column data of the (j−a) -th column. In addition, an algorithm for selectively distributing image data is set.
[0003]
A typical operation form of this scroll display system includes the following advertisement display. Install a display screen in the busy area of the downtown area. Many advertisers are recruited, and image data of advertisement messages according to each request is created and stored in the hard disk of a personal computer, which is the core of the system. Here, a series of image data having an arbitrary length in the scroll direction used for scroll display as a group of images is referred to as one program.
A large number of programs requested by each advertiser are each assigned a program ID for management. By passing the program ID to the display execution process, bitmap image data corresponding to the program ID is copied to the working memory area. Scroll display is performed by distributing and transferring the image data to the display device.
Also, even if a company operates as a dedicated advertising display, a variety of programs are produced in advance according to the seasons and days of the week or specific holidays, and also in the morning, noon, night, etc. A database is created by distinguishing by program ID. Then, it is operated while designating which program is to be displayed at a certain time on a certain day.

DETAILED DESCRIPTION OF THE INVENTION
=== Physical screen and virtual screen ===
As shown in FIG. 1A, 16 high-intensity LED lamps L1 to L16 are linearly arranged at a close interval along an elongated pole-shaped housing to constitute one pole-type display unit Bi. In the example shown in the figure, 32 display units B1 to B32 are prepared, and these are arranged almost parallel at a sparse interval. Flying vertical columns consisting of 32 display units B1 to B32 are arranged in a horizontal band in the form of vertical dots of 16 dots and horizontal rows of sparse 32 dots (16 × 32). Configure the physical screen. In this embodiment, the arrangement interval of the 32 display units B1 to B32 is about four times the vertical interval of the LED lamps in one display unit Bi.
[0014]
In the physical screen of the flying dot row shown in FIG. 1 (a), as shown in FIG. 1 (b), three dot rows are virtually arranged in the row spacing portion of the sparse 32 rows. Then, a virtual screen with a uniform dot distribution having a (16 × 125) dot configuration with a dot density substantially equivalent to a dense 16-dot vertical arrangement is assumed. That is, a screen that is assumed to have three display units arranged at equal intervals in an interval between two adjacent display units is referred to as a virtual screen.
[0015]
=== Principal operation of scroll display ===
The relationship between the physical screen of the (16 × 32) dot configuration flying dot row, the virtual screen of the uniform dot distribution of (16 × 125) dot configuration, and the bitmap image data to be scroll-displayed on this screen. It is shown in FIG. In the example of FIG. 2, an image of five characters “Aiueo” is scroll-displayed in the horizontal direction with a suitable space. The character font in this example has a (16 × 16) dot configuration.
[0016]
Assume that the image data for 5 characters to be displayed is bitmap data with 16 dots in one column and 125 dots in one row including a space between characters (this is called one program). As shown in FIG. 2, the image data of (16 × 125) dots is developed and displayed on a virtual screen with a uniform dot distribution having a (16 × 125) dot configuration. As actual display control, 32 columns of image data selected from 125 columns of image data are distributed to 32 display units B1 to B32, and each display unit is in accordance with 16 columns of data. The 16 lamps L1 to L16 in Bi are controlled and driven.
[0017]
In the control to select 32 rows of image data from among 125 rows of image data and distribute them to 32 display units B1 to B32, the row intervals of the skip selection are distributed and arranged on the virtual screen. It is determined corresponding to the arrangement interval of the display units B1 to B32. That is, in the example of FIGS. 1 and 2, one column is extracted for every four columns in the image data and distributed to the display units B1 to B32.
[0018]
Then, while moving the bitmap image data developed on the virtual screen in the row direction, the data processing for controlling and driving the lamps L1 to L16 of the display units B1 to B32 is repeated according to the image data selected as described above. Thus, as illustrated in FIGS. 2A, 2B, and 2C, a scrolling image having a density of 16 dots per row and 125 dots per row due to the visual afterimage effect of a person observing a virtual screen. Make it visible.
[0019]
=== Overview of Display Control System ===
An overall outline of the data processing system of the system of the present invention is shown in FIG. A general personal computer can be used as the computer 1 serving as the center of the system. A dedicated data transfer circuit 2 is coupled to the expansion bus of the computer 1. The data transfer circuit 2 and 32 display units B1 to B32 are daisy chain connected by a transmission cable 3. An image memory 11 and a transfer buffer 12 for scroll display processing are set on the main memory of the computer 1. The hard disk device 13 of the computer 1 stores a large number of image data to be scrolled in units of handling called programs.
[0020]
The display unit Bi is a lamp driving circuit 4 that drives the lamps L1 to L16 for 16 dots, and data processing that relays and transfers the image data from the computer 1 and takes in the image data addressed to itself and supplies it to the lamp driving circuit 4. Circuit 5. The data processing circuit 5 has an input end connector IN and an output end connector OUT. The plug of the transmission cable 3 is fitted into this connector, and each element is daisy chain connected.
[0021]
=== Signal sent from data transfer circuit ===
The details of the lamp driving circuit 4 and the data processing circuit 5 in the display unit Bi are shown in FIG. 4, and the timing of the image data and the synchronization signal sent from the data transfer circuit 2 of the computer 1 to each of the display units B1 to B32 connected in a daisy chain. The relationship is shown in FIG.
The 16 lamps L1 to L16 included in one display unit Bi can each emit multicolor light consisting of RGB collective lamps. In this embodiment, it is assumed that one lamp is driven by data of 3 bits in total of 1 bit for each of RGB. A 3-bit set of RGB is image data for one dot.
[0022]
From the data transfer circuit 2, image data, a dot synchronization signal DCK, a unit synchronization signal UCK, a frame synchronization signal FCK, and a lamp driving pulse LDP are sent out. In synchronization with each clock of the dot synchronization signal DCK, 3-bit parallel image data for one dot is output in series. Image data for 16 dots to be distributed to the display unit Bi is continuously output. The first 16 dots of image data are data addressed to the first display unit B1, the subsequent 16 dots of image data are data addressed to the second display unit B2, and the further subsequent 16 dots of image data are data. The image data and the dot synchronization signal DCK are sequentially output so that the data is addressed to the third display unit B3.
[0023]
One clock of the unit synchronization signal UCK is output every 16 clocks of the dot synchronization signal DCK. That is, the unit synchronization signal UCK is a clock synchronized with a unit of one unit of image data output in series = 16 dots.
In this embodiment, a physical screen is composed of 32 display units B1 to B32. The data transfer circuit 2 outputs one clock of the frame synchronization signal FCK when starting to output image data for one screen = 32 units to be distributed to the 32 display units B1 to B32. That is, the frame synchronization signal FCK is a clock synchronized with the division of one screen = 32 units of serially output image data.
[0024]
=== Control System in Display Unit Bi ===
As shown in FIG. 4, the lamp drive circuit 4 of the display unit Bi includes a driver 41 that drives each of the 16 lamps L1 to L16 with RGB 3-bit data, and image data for 16 dots in the driver 41. And a shift register 43 that takes in 16-dot image data transferred in series and supplies the image data to the latch circuit 42 in parallel.
[0025]
Further, with the circuit configuration shown in detail in FIG. 4, the data processing circuit 5 of the display unit Bi relays image data from the computer 1 and captures image data addressed to itself.
The image data input from the previous stage is slightly delayed by the delay circuit 51 and sampled by the latch circuit 52 at the timing of the dot synchronization signal DCK to perform waveform shaping and timing adjustment, and the shift register 43 of the lamp driving circuit 4 Data is input and output to the subsequent stage.
The dot synchronization signal DCK and the frame synchronization signal FCK input from the previous stage are output to the subsequent stage via the buffer 58 and the buffer 59, respectively. The unit synchronization signal UCK input from the previous stage is slightly delayed by the delay circuit 61 and sampled by the latch circuit 62 at the timing of the dot synchronization signal DCK, so that waveform shaping and timing adjustment are performed. A unit synchronization signal UCK is output to the subsequent stage via the AND gate 55.
[0026]
The two flip-flops 53 and 54 are reset at the rise of the frame synchronization signal FCK from the previous stage. At the rise of the unit synchronization signal UCK from the previous stage, the two flip-flops 53 and 54 read their D inputs. The D input of the first stage flip-flop 53 is always “1”, and the Q output thereof is the D input of the second stage flip-flop 54.
Therefore, when the first unit synchronization signal UCK is input after being reset by the frame synchronization signal FCK, the flip-flop 53 is set (Q output becomes “1”), and the flip-flop 54 remains reset. is there.
Subsequently, when the second unit synchronization signal UCK is input, the flip-flop 54 is also set and its Q output becomes “1”. Once the flip-flops 53 and 54 are set, they remain set until the next frame synchronization signal FCK is input.
[0027]
The unit synchronization signal UCK from the previous stage is output to the subsequent stage via the AND gate 55. A Q output of the flip-flop 54 is applied to the AND gate 55 as a gate signal. As described above, the flip-flop 54 remains reset when the first unit synchronization signal UCK is input after the frame synchronization signal FCK is input, and is set at the rising edge of the second unit synchronization signal UCK. . Accordingly, the first unit synchronization signal UCK does not pass through the AND gate 55, and the second and subsequent unit synchronization signals UCK pass through the AND gate 55 and are output to the subsequent stage.
[0028]
The Q output of the flip-flop 53 and the inverted Q output of the flip-flop 54 are ANDed by an AND gate 56. Therefore, the output of the AND gate 56 becomes “1” only during the period from the rising edge of the first unit synchronization signal UCK after the input of the frame synchronization signal FCK to the second rising edge. When the output of the AND gate 56 becomes “1”, the dot synchronization signal DCK from the previous stage passes through the AND gate 57 and is applied to the clock input terminal of the shift register 43. In synchronization with the clock input at this time, the image data passed through the latch circuit 52 is shifted into the shift register 43.
[0029]
I will explain it again. After the frame synchronization signal FCK is input from the previous stage, the dot synchronization signal DCK from the previous stage is input to the shift register 43 only during the period from the rising time of the first unit synchronization signal UCK input from the previous stage to the second rising time. The image data from the previous stage is shifted into the shift register 43 in synchronization with the clock. During this period, image data for 16 dots = 1 unit is input from the preceding stage in synchronization with 16 clocks of the dot synchronization signal DCK. The image data for one unit is read into the shift register 43.
[0030]
Here, the interval period of the frame synchronization signal FCK generated by the computer 1 is called a frame cycle. The 32 unit synchronization signals UCK issued from the computer 1 in the frame cycle are referred to as UCK1, UCK2, UCK3,.
In the first display unit B1 closest to the computer 1, all 32 unit synchronization signals UCK1, UCK2, UCK3,... UCK32 are inputted, and an image for one unit inputted during the period of UCK1 to UCK2. Data is taken into the shift register 43 of the display unit B1.
UCK1 is not transmitted to the display unit B2 in the second stage, UCK2, UCK3, UCK4,. Of the shift register 43.
UCK2 is not transmitted to the display unit B3 in the third stage, and UCK3, UCK4, UCK5,. Of the shift register 43.
Then, only UCK32 is input to the display unit B32 at the last stage, and image data for one unit input during a period from the input time point of UCK32 to the input time point of the frame synchronization signal FCK at the beginning of the next frame cycle. Is taken into the shift register 43 of the display unit 32.
[0031]
As described above, image data for one screen = 32 units serially output from the computer 1 during one frame cycle is sequentially distributed to the 32 display units B1 to B32, and each shift register 43 is provided. Is taken in. Then, when the frame synchronization signal FCK indicating the start of the next frame cycle is output from the computer 1, the frame synchronization signal FCK becomes a strobe signal of the latch circuit 42 in all the display units B1 to B32, and the image of the shift register 43 is displayed. Data is read into the latch circuit 42. At the same time, the lamps L1 to L16 are driven to emit light according to the image data read into the latch circuit 42.
By repeating the data processing of the above frame cycle at high speed, the tracking interpolation type scroll display is realized on the screen of the flying dot row composed of 32 display units B1 to B32.
[0032]
=== Control of scrolling speed ===
As described above, by repeating the data processing of the frame cycle at a high speed, the tracking interpolation type scroll display is realized on the screen of the flying dot row composed of 32 display units B1 to B32. The scroll speed of the display is determined by the frame cycle, that is, the cycle of the frame synchronization signal FCK. The frame synchronization signal FCK is generated in the data transfer circuit 2, and its cycle is variably set by a cycle command value from the computer 1. That is, the computer 1 appropriately selects the scroll speed, and gives a cycle command value to the data transfer circuit 2 accordingly, and variably sets the cycle of the frame synchronization signal FCK.
[0033]
It is assumed that the minimum value of the period of the frame synchronization signal FCK (maximum value of the scroll speed) is determined as appropriate. On the other hand, the data transfer time for distributing the image data for one screen to the 32 display units B1 to B32 by the dot synchronization signal DCK and the unit synchronization signal UCK is sufficiently short and smaller than the minimum value of the cycle of the signal FCK. Therefore, even if the frame synchronization signal FCK is variably controlled, it is not necessary to change the data transfer processing speed using the dot synchronization signal DCK or the unit synchronization signal UCK. If necessary, change it.
[0034]
=== Control of display brightness ===
In order to variably control the display brightness of each LED lamp of each display unit Bi, a 1 KHz lamp driving pulse LDP is output from the data transfer circuit 2. The lamp driving pulse LDP is transmitted in series to all the units Bi through the buffer 70, and is applied to the control input DP of the driver 41 in each unit Bi. The display brightness of the LED lamp is changed by changing the duty ratio (pulse width) of the 1 KHz lamp driving pulse LDP. Increasing the duty ratio of the pulse LDP increases the lamp brightness, and decreasing the duty ratio decreases the brightness.
[0035]
The duty ratio of the lamp driving pulse LDP generated in the data transfer circuit 2 is variably set according to the luminance command value from the computer 1. In other words, the display brightness is appropriately selected in the computer 1, the brightness command value is given to the data transfer circuit 2 accordingly, and the duty ratio of the lamp driving pulse LDP is variably controlled.
[0036]
=== Programs and Databases ===
The computer 1 is based on a general personal computer, and includes a keyboard, a mouse (pointing device), a CRT monitor, and the like as peripheral devices for man-machine interface. As described above, the image memory 11 for the scroll display processing and the transfer buffer 12 are set on the main memory of the computer 1, and the hard disk device 13 handles many types of image data to be scrolled as a program. Accumulated in units and made into a database.
As shown in FIG. 6, each program file in the database is aggregated using a program ID as a key. Each program file is accompanied by a program name in which the contents of the image are expressed in Japanese characters and control parameters in addition to the bitmap-format image data as the main body.
[0037]
=== Program set (title) ===
The processing unit of the scroll display control is the aforementioned program, but the management unit of the display schedule in the system operation is the aforementioned program set. In this embodiment, the program set is called a title.
A title (program set) is a permutation of IDs of a plurality of assembled programs. As will be described later, each program is cyclically displayed according to the permutation. The program content of the title can be freely edited by the system operator. When “title editing mode” is selected on the schedule management menu selection screen in the computer 1, a title editing screen as shown in FIG. 7 is displayed.
In FIG. 7, in the right half of the screen, the program names of the programs registered in the program database are listed in Japanese characters. The left half of the screen is a column for entering a plurality of program names to be aggregated as a certain title ID, for example, “title 1”. By designating an arbitrary program name from the list display of program names in the right column with the cursor and clicking the arrow icon in the center with the mouse, the program name is also displayed in the left column. Thus, the program is registered in “Title 1”.
[0038]
By operating the personal computer as described above, an arbitrary number of program names are arranged in an arbitrary order in the left half column, and the contents of “title 1” are edited. Similarly, a plurality of titles such as “title 2” and “title 3” can be freely edited. The edited program contents of each title are aggregated in the form of a title table (program set table) and stored in an appropriate storage unit (such as the hard disk device 13). The concept of the title table is shown in FIG. This is a simple table content in which permutations of a plurality of program IDs assembled are associated with each title ID.
[0039]
=== Schedule management table ===
A schedule management table is created in an appropriate storage unit (such as the hard disk device 13) of the computer 1. In the schedule management mode, the set schedule management table is displayed on a screen as shown in FIG.
As shown in FIG. 9, in the schedule management table, the framework for one day is divided into frameworks (time frames) in units of one hour. As an incidental function, brightness parameters can be arbitrarily entered individually in 24 time frames for one day. The luminance parameter of this time frame is a numerical value in percentage with the maximum luminance being 100. Normally, the brightness parameter in the bright daytime is set to 100, and is set to 80, for example, so as to lower the display brightness appropriately at night when the surroundings are dark. Apart from the luminance parameter for each time frame, one basic luminance parameter can be arbitrarily set. This is determined by considering factors such as the environmental conditions in which each display device is installed and the power supply capacity, and is a numerical value that determines what percentage of the maximum luminance is the upper limit of the rated maximum luminance of the display device. .
[0040]
In the title name column at the left end of the schedule management table, the name of the title edited and registered in the “title editing mode” described above is automatically written. In the schedule management table illustrated in FIG. 9, three titles “Christmas”, “Animation”, and “New Year” are registered. Then, set the time zone to display each title by putting a circle in the square of the corresponding time frame (when you place the cursor on the square and click, it will be marked with Click to clear the circle).
[0041]
=== Procedure for executing display ===
The computer 1 performs control for program display according to the procedure shown in the flowchart of FIG. 10 based on the schedule management table. In the first step 401, it is recognized to which time frame of the schedule management table the current date and time indicated by the calendar and the clock attached to the computer 1 belongs, and it is determined whether or not the display schedule is set in the corresponding time frame. If the title to be displayed is set, the title ID is acquired. In step 402, the title table (program set table) is examined to obtain a permutation of a plurality of program IDs aggregated in the corresponding title, and the program file of each program ID is read from the hard disk device 13, The image data of each program is developed in the image memory 11 as a bitmap.
[0042]
In the next step 403, the head address of the image data of the program to be displayed next in the program sequence of the corresponding title is set in the register s. Further, the scroll speed parameter written in the program file is acquired, and a cycle command value corresponding to the parameter is given to the data transfer circuit 2. Thus, the cycle of the frame synchronization signal FCK is determined. In addition, the brightness parameter written in the program file, the brightness parameter set in the current time frame of the schedule management table, and the environmental conditions and power capacity of each display device are set together. Based on the basic brightness parameter, a brightness command value for displaying the program is calculated, and the brightness command value is given to the data transfer circuit 2. Thus, the duty ratio of the lamp driving pulse LDP is determined.
[0043]
After the above preprocessing, the display sequence is started. It should be noted that the image data of each program that has been bitmap-developed in memory has a vertical size of 16 dots (1 dot is a total of 3 bits of RGB) and a horizontal size. The data for 16 vertical dots is referred to as column data, and each column data is sequentially numbered D1, D2, D3,... (General term is expressed as Dj). For simple explanation, it is assumed that the image memory 11 has a configuration in which one word is (16 × 3) bits and column data Dj is stored at an address j.
[0044]
First, in step 502, the start pointer P is set to 1, and in the next step 503, the value of the start pointer P is moved to the address pointer j (j = P = 1 in this description stage). In step 504, the column counter C is set to 1.
In the next step 505, the image memory 11 is read-accessed at the address j indicated by the address pointer j, and the read column data Dj is written to the address C indicated by the column counter C in the transfer buffer 12. In the next step 506, 4 is added to the address pointer j. Here, instead of adding 1 to the address pointer j, “add 4 to j” directly represents a feature of the tracking interpolation scroll display system.
[0045]
In the next step 507, it is checked whether or not the value of the column counter C has reached the final value n = 32. Until C = 32, 1 is added to the column counter C in step 508, and then the process returns to step 505. The image memory 11 is read-accessed according to the address pointer j updated in step 506, and the column data Dj is transferred to the transfer buffer 12. Write to the updated address C. If C = 32, the display data for 32 columns to be transferred to the 32 display units B1 to B32 is aligned in the transfer buffer 12.
[0046]
In step 509, the column data D1 to D32 for 32 columns on the transfer buffer 12 are output from the data transfer circuit 2 to each display unit Bi. This data transfer operation has already been described in detail. In the next step 510, 1 is added to the start pointer P, and preparation is made to advance the image to be displayed by one unit in the scroll direction. In the next step 511, it is checked whether or not the value of the start pointer P has reached a value MAX indicating the edge of the image to be displayed. Until P = MAX, the process returns to step 503 to scroll the image.
[0047]
When P = MAX, the routine proceeds to step 512, where it is determined whether or not the end time of the time frame currently being displayed has passed. If not, the routine proceeds to step 513, where the current processing target title is selected. The program is switched to the next program, and the process returns to step 403 to perform initial setting according to the new program and execute the display sequence after step 502. If the end time of the time frame has passed, the process returns from step 512 to the first step 401.
[0048]
【The invention's effect】
According to the present invention, it is very easy to manage the operation schedule of which programs are displayed in what order. Even those in charge of operations who do not have special expertise to handle information devices such as personal computers can freely select from a large number of programs in the database and edit schedules freely. It is easy to display the program in the desired combination at the desired time. This dramatically increases the practicality and usefulness of the system.
