Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a timepiece image display device for displaying an analog timepiece image on a television screen.

[0002]

As is well known, for example, a CRT (Cathode)
A television receiver capable of displaying an analog clock on a television screen such as a Ray Tube) has been conventionally configured as shown in FIG. That is, in FIG. 9, the microprocessor 11 generates dial display data for displaying the dial of the analog watch as an image, and based on the time information supplied to the input terminal 12, the minute hand of the analog watch. The pointer display data for displaying the image of the short hand or the short hand is generated.

The dial display data and the pointer display data output from the microprocessor 11 are CR
By being supplied to the T controller 13, the color signals R, G, B in dot units are converted. After that, the analog timepiece display color signals R, G, and B output from the CRT controller 13 are supplied to the image signal processing circuit 14 to be subjected to amplification processing, and then supplied to the CRT 15 so as to generate dots. The image is displayed as an aggregate. Figure 10
Indicates a pointer (at 1:22) of an analog timepiece, which is displayed as an image in dot units on the screen of the CRT 15.

The television broadcast signal received by the antenna 16 is supplied to a signal processing circuit 17 where it is subjected to channel selection processing and intermediate frequency conversion processing. And
The image signal output from the signal processing circuit 17 is supplied to the image signal processing circuit 14, whereby the color signals R, G, and
The image is displayed by the CRT 15 after conversion processing to B, combination processing with the color signals R, G, and B for analog type clock display output from the CRT controller 13 and the like.

However, in the image display means of the above analog type timepiece, the dial display data and the pointer display data output from the microprocessor 11 are the CRT.
The controller 13 controls the color signals R, G, and
Since it is converted into B and is displayed as an image on the CRT 15 as an aggregate of dots, there is a problem that it takes a long time for the pointer display data output from the microprocessor 11 to be completely displayed on the screen of the CRT 15. ing. For this reason, the switching of the display position of the pointer with the passage of time seems unnatural and is difficult for the user to see.

[0006]

As described above, in the conventional image display means for displaying the image of the analog type clock on the television screen, it takes a long time to display the image, so that the display position of the pointer is changed. Has the problem that it looks unnatural.

Therefore, the present invention has been made in consideration of the above circumstances, and provides a very good timepiece image display device which can perform high-speed and high-quality image display and is economically advantageous. The purpose is to do.

[0008]

A timepiece image display device according to the present invention is intended for displaying an analog timepiece image consisting of long hands and short hands on a television screen. Then, a time data generating means for generating time data by counting a reference signal of a constant cycle, and a plurality of display patterns of the long hand, which is a collection of fonts composed of a plurality of dots, are prepared and output from the time data generating means. Time data is prepared by providing a plurality of short hand display patterns with a font aggregate composed of a plurality of dots and a long hand display data generating means for outputting a signal for displaying a display pattern corresponding to the time data. Short hand display data generating means for outputting a signal for displaying a display pattern corresponding to the time data output from the generating means, a signal output from the long hand display data generating means and a short hand display data generating means. And a display means for combining the signal and displaying it on the television screen.

In the timepiece image display device according to the present invention, in the above object, when the time adjustment is requested, the display is switched so that the time is displayed numerically on the television screen instead of the display of the long hand and the short hand. It is equipped with means.

Further, the timepiece image display device according to the present invention is intended for displaying an analog timepiece image consisting of a dial, long hands and short hands on a television screen. Then, the time data generating means that counts the reference signal of a constant cycle to generate the time data, the detecting means that detects that the reference signal is not supplied to the time data generating means, and the detection result of the detecting means.

[0011]

According to the above-described structure, first, a plurality of display patterns of the long hand and the short hand are prepared in the font group, and the two display patterns are combined to display the analog timepiece image. Therefore, it is possible to reduce the time required for display to each step compared to the conventional display in dot units, and since the two display patterns of the long hand and the short hand are combined, It is possible to significantly reduce the number of fonts, which is economically advantageous, as compared with the method of preparing a display pattern in which the above are combined.

Further, when the time adjustment is required, instead of displaying the long hand and the short hand, the time is displayed numerically on the television screen, so that the desired time can be promptly set at the time adjustment. You will be able to set it.

Further, since the display form of the dial is changed by detecting that the reference signal is no longer supplied to the time data generating means for generating the time data, the time indicated by the analog clock is accurate to the present time. It is possible to easily notify the user of the difference from the above, and to prevent the wrong timer setting.

Further, the microprocessor 20 executes the control processing so as to realize the selected mode when the mode of the timer function is selected and set by the key operation unit 23.

When the clock display mode is selected and set by the key operation unit 23, the microprocessor 20
Generates dial display data for displaying the image of the dial of an analog watch, and based on the time data generated by itself, the minute hand display data and the minute hand display data for displaying the minute and hour hands of the analog watch as an image. Are generated respectively. And this microprocessor 20
The dial display data and the minute hand display data output from the above are supplied to an OSD (On Screen Display) circuit 24. The short hand display data output from the microprocessor 20 is also supplied to another OSD circuit 25.

These OSD circuits 24 and 25 function as so-called character generators. That is, the OSD circuit 24 makes a plurality of dots (for example, 6 dots in the horizontal direction × 4 dots in the vertical direction = 24 dots) based on the input dial display data and long hand display data.
The color signals R, G, and B for displaying the image of the dial and the minute hand are generated for each font unit constituted by. Also, the OS
The D circuit 25, based on the input short hand display data,
Color signals R, G, and B for displaying the short hand as an image are generated for each font unit.

Here, the color signals R, G, corresponding to the dial and the minute hand and the minute hand generated by the OSD circuits 24, 25, respectively.
B is time-divided to another switch circuit 27 by the switch circuit 26. The switch circuit 27 includes analog color clock display color signals R, G, and B derived from the switch circuit 26, and a color signal R output from the microprocessor 20 for image display of, for example, a volume level or a channel. , G, B are led to the image signal processing circuit 28 in a time division manner.

The CRT 29 is subjected to conversion processing into B, composition processing with the color signals R, G, B derived from the switch circuit 27, and the like.
Will be displayed as an image.

Here, FIG. 3 shows the analog type timepiece as C.
9 is a flowchart showing the processing operation of the microprocessor 20 when displaying an image on the RT29 screen. First, when the clock display mode is selected and set by the key operation unit 23 and a display of an analog clock is requested (step S1), the microprocessor 20 causes the step S2 to be performed.
Then, the dial display data including the display data indicating the shape of the dial and the position data for designating the display position on the CRT 29 screen is generated and output to the OSD circuit 24.

Thereafter, the microprocessor 20 calculates the display data indicating the shape of the long hand in step S3, and specifies the display position of the long hand on the CRT 29 screen based on the time data generated by itself in step S4. Position data is generated, and the minute hand display data composed of these display data and position data is output to the OSD circuit 24 in step S5. In addition, the microprocessor 20 calculates the display data indicating the shape of the short hand in step S6, and, in step S7, the position for designating the display position of the short hand on the CRT 29 screen based on the time data generated by itself. Data is generated, and in step S8, the short hand display data composed of these display data and position data is output to the OSD circuit 25, and the processing operation is ended (step S9).

Then, from the OSD circuit 24, the color signals R for displaying the dial and the long hand in units of fonts are displayed.
G, B are generated, and the OSD circuit 25 generates color signals R, G, B for displaying an image of the short hand in font units, and the image display by both color signals R, G, B is combined. As a result, as shown in FIG. 4, an analog clock is displayed as an image on the screen of the CRT 29.

According to the configuration as in the above embodiment, the OSD circuits 24 and 25 output the dial / long hand display data and the short hand display data output from the microprocessor 20 to the color signal of a unit of a plurality of dots. R, G,
Since the image is displayed on the CRT 29 as a set of fonts by converting it into B, the time required for the display data output from the microprocessor 20 to be completely displayed on the screen of the CRT 29 is reduced to the conventional one. It can be shortened to each stage as compared with the display in dot units. Therefore, the display position of the pointer can be switched at high speed with the passage of time, and a display that is not unnatural for the user and can be viewed easily can be performed.

Further, for example, the hour and minute hands of an analog type clock displayed on the screen of the CRT 29 as shown in FIG.
As shown in (a) and (b), it is composed of 6 fonts and 4 fonts, respectively, and if the display position of each pointer is switched in units of 1 minute, 60 patterns of one minute hand of an analog type clock are displayed. The total number of fonts required to do is 6 x 60
= 360 fonts, and the total number of fonts required to display one rotation of the short hand is 4 × 60 = 240 fonts, which is sufficiently suitable for practical use.

Further, the long hand display data and the short hand display data are converted into color signals R, G, B in units of fonts by the OSD circuits 24, 25, respectively, and these color signals R,
Since G and B are combined on the CRT 29 screen and displayed as an image, the total number of fonts is also reduced in this respect.

That is, the minute hands and the minute hands of the analog type timepiece are not separately prepared as separate patterns in font units, and all the patterns necessary for displaying the analog type timepiece in which the minute hands and the minute hands are combined are in font units. If it is prepared in, the total number of fonts (360 + 240) necessary to display the minute hands and the minute hands of the analog type clock mentioned above is displayed.
= 600 fonts), the total number of fonts for displaying a pattern in which the long hand and the short hand overlap (for example, 2:10) is added, and the ratio of the total number of fonts for displaying the same pattern is added to these totals ( This is because it becomes necessary to prepare thousands of fonts that are multiplied by 100%, and it becomes extremely unsuitable for practical use.

Next, the case where the time is adjusted will be described. This time adjustment is CR in the above clock display mode.
This is realized by requesting the time setting mode by operating the key operation unit 23 while the analog timepiece is displayed on the T29 screen. When this time adjustment mode is set, the microprocessor 20 erases the indication of the minute hand and the minute hand, leaving only the dial display of the analog type timepiece, as shown in FIG. Operates to display a digital watch in the center of the dial.

Then, the user operates the key operation unit 23 to set the desired value by moving the time digit and the minute digit of the digital timepiece forward or backward respectively, and then the key operation unit 23. The time adjustment work is completed by performing the operation of time adjustment completion.

FIG. 7 shows the time adjustment mode.
9 is a flowchart showing a processing operation of a microprocessor 20 when an image of a digital timepiece is displayed on a CRT 29 screen. First, when the time adjustment mode is requested by the key operation unit 23 in the state where the clock display mode is selected and set (step S10), the microprocessor 20 displays the display data indicating the shape of the dial in step S11. Dial face display data including position data for designating the display position on the CRT 29 screen is generated and output to the OSD circuit 24.

Thereafter, in step S12, the microprocessor 20 generates time display data for displaying the two-digit numerical value representing the time of the digital timepiece and the two-digit numerical value representing the minute in the OSD circuit. Then, the processing operation is finished (step S13). Then, the OSD circuit 24 outputs the color signals R, G, B for displaying the image of the dial in font units, and for displaying the 4-digit numerical value representing the hour and minute of the digital clock as an image. The color signals R, G and B are output, and the digital timepiece is displayed as an image on the screen of the CRT 29 as shown in FIG.

As described above, when the time is set, the analog timepiece display is switched to the digital timepiece display, so that the user can perform the time adjustment work quickly and accurately. That is, as described above, by converting the long hand and short hand display data output from the microprocessor 20 into color signals R, G, B of a font unit composed of a plurality of dots and displaying the image, the conventional dot is displayed. Although it is possible to speed up the display operation of the pointer as compared with the display unit in units, in order to actually display the pointer as an image, it is necessary to perform the processing shown in the flowchart of FIG. is there.

Therefore, if the time is adjusted while the analog type clock is still displayed, when the user moves the hands at high speed to adjust the position of the hands at a desired time, the continuous processing of the flowchart shown in FIG. 3 is performed. Therefore, the user feels the moving speed of the pointer slowly.
However, the display operation of the digital timepiece is much simpler than the display operation of the hands as shown in the flowchart of FIG. 7, so that the time digit and the minute digit can be swiftly adjusted when adjusting the time. The desired value can be set.

When the time adjustment is completed and the timepiece display mode is returned to, the time display is immediately performed by the analog timepiece corresponding to the time set by the time adjustment, so that the position of the hands is accurately set. Can be matched.

Further, as described above, the time is measured by the microprocessor 20 counting the number of cycles per unit time of the reference signal in which the level of the commercial AC voltage supplied to the input terminal 21 is limited by the attenuator 22. Has been done. Therefore, the microprocessor 20
For example, when the commercial AC voltage is not applied to the input terminal 21 due to a power failure or the plug is pulled out from the outlet, that is, when the reference signal is not supplied, the time counted up to that point is reset and the reference signal is restarted. When is supplied, it operates so as to count the time from 00:00, for example.

In this case, of course, the CRT 29
The time indicated by the analog clock displayed on the screen is
It will be different from the exact current time, but for the user,
It may be difficult to distinguish whether the time has been reset once, and the timer may be set without knowing that the time has been reset.

Therefore, when the time is once reset, the microprocessor 20 assumes that an analog clock as shown in FIG. 8 is displayed on the screen of the CRT 29.
It works to make the dial blink. This allows
The user can recognize that the time indicated by the analog clock displayed on the screen of the CRT 29 is different from the current time, and can prevent erroneous timer setting.

In this case, it is possible to blink the entire dial, for example, 00 minutes, 05 minutes, 10 minutes, 15 minutes, 2
0 minutes, 25 minutes, 30 minutes, 35 minutes, 40 minutes, 45 minutes, 50
It may be a part of the dial such as the positions of minutes and 55 minutes. Further, the colors of the dial may be alternately switched, for example, red, blue, red, blue, .... The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.

[0040]

As described above in detail, according to the present invention,
It is possible to provide a very good timepiece image display device that can perform high-speed and high-quality image display and is economically advantageous.
