Set the one that is suitable for the result of the switching.

That is, since it is possible to select the operation of switching the date format and the operation of switching the information to be displayed in an arbitrary order, these operations are repeated in series by repeating a specific operation. The operability is greatly improved compared to the conventional example that has been performed. In the display device according to the third aspect of the present invention, the control register 33 has, as information to be imprinted on the image, mode identification information indicating a combination of one or both of the date and the time, and the date and the time. Among them, the display form identification information indicating which one should be displayed on the display 32 is set. The display item setting means 34 selects one of the date and time given by the clock 31 corresponding to such display form identification information and gives it to the display 32, and the display form identification information shows the time, Further, when the mode identification information set in the control register 33 as described above indicates both the date and the time, among the segments forming the display 32,
A combination of specific segments that are not used for displaying the time is set to a lighting state.

That is, the fact that the information to be imprinted on the image includes the date is surely displayed by using the remaining segment in which the time is not displayed even when the time is displayed on the display 32. . Therefore, the existing segment of the display 32 is effectively used, and an increase in the number of signal lines involved in display control can be suppressed.

In the display device according to a fourth aspect of the present invention, in the display device according to the third aspect, the display form identification information set in the control register 33 includes a year which is a date imprinted on an image, Date format identification information is included that indicates a permutation of month, day values, and the combination of a particular segment forms a letter or symbol that identifies the aspect of that permutation.

That is, in the remaining segment in which the time is not displayed, the format of the date is surely displayed in addition to the fact that the information to be imprinted on the image includes the date. This segment is used more effectively, and the increase in the number of signal lines involved in display control can be suppressed. In the display device according to the invention described in claim 5,
The combination of a specific segment that indicates that the information to be imprinted on the image includes a date and the format of the date is either the year, month, or day in the permutation of the year, month, and day indicating the format. Form a permutation of letters or symbols that indicate one or two.

That is, regarding the format of the date imprinted on the image with the time displayed on the display 32, the redundant characters and symbols indicating the format are eliminated and displayed. The processing relating to display control can be simplified.

It should be noted that these drive level values “0”, “1”, and “2” are respectively “off state”, “lighting state”, and “control table 91F”. Either one of the extinguished state and the lit state given by "."

The control unit 82 monitors the initial setting and updating of the values of the mode register 51, the date format register 52 and the status register 53, and when the initial setting and updating are performed, the control unit 82 of the mode register 51 at that time point is monitored. The value M is compared with "0". Further, when the value M of the mode register 51 is “0” as a result of such comparison, the control unit 82 recognizes that it is in the standard mode state, and refers to the state register 53 to determine the value s. Ask for. Then, the control unit 82 controls the control table 91 based on the value s.
S The drive levels individually corresponding to the first year segment 83, the second year segment 84, the first month segment 85, the second month segment 86 and the hour / minute mode display unit 126 are obtained by referring to Drive level is "0",
If it is any one of "1", it is given as it is to the corresponding segment and display section. However, the control unit 8
When the drive level thus obtained is "2", the reference numeral 2 refers to the date format register 52 to obtain its value d. Then, the control unit 82 controls the control table 91F based on the value d. See first year segment 8

And drive levels individually associated with the second lunar segment 86 are determined and these drive levels are provided to the individually corresponding segments.

That is, in the standard mode, when the value s of the status register 53 indicates that nothing is displayed on the display 81, the first year segment 83, the second year segment 84, and the first month. The segment 85, the second month segment 86, and the hour / minute mode display unit 126 are all set to the off state, and the value s indicates that only the time should be displayed on the display 81 and is included in the time. When indicating the update state of the hour value or the minute value, all of the first year segment 83, the second year segment 84, the first month segment 85 and the second month segment 86 are set to the off state. Then, the hour / minute mode display unit 126 is set to the lighting state. Furthermore, when the value s of the status register 53 indicates that the date should be displayed on the display 81, and when the value of any one of the year, month, and day included in the date is updated, the hour / minute mode is set. The display unit 126 is set to the off state,
And the first year segment 83, the second year segment 8
4, Regarding the first month segment 85 and the second month segment 86, only one of the first month segment 85 and the second month segment 86 corresponding to the date format indicated by the value d of the date format register 52 is set to the lighting state and the other three. Is set to off.

If the value M of the mode register 51 is not "0" by the above comparison, the control unit 82 recognizes that it is in the full mode and refers to the date format register 52 to determine the value. Find d. Subsequently, the control unit 82
Is a control table 91F based on the value d. The drive levels individually corresponding to the first year segment 83, the second year segment 84, the first month segment 85, and the second month segment 86 are obtained by referring to the above, and these drive levels are individually corresponded. Give to the segment. Further, the control unit 82 obtains the value s of the state register 53 at that time, and when the value s is "0" or "1", sets the drive level of the hour / minute mode display unit 126 to "0". On the contrary, when the value s is "2", the drive level is set to "1" and the hour / minute mode display unit is driven.

That is, in the full mode, for the first year segment 83, the second year segment 84, the first month segment 85 and the second month segment 86, the date indicated by the value d of the date format register 52 is set. Only the ones corresponding to the type of are set to the lighting state and the others are set to the non-lighting state (FIGS. 11A to 11C), and the hour / minute mode display unit 1
Reference numeral 26 is set to a lighting state only when the time is displayed on the year / month / day display section 123, the month / date / time display section 124 and the year / minute display section 125 (FIGS. 11 (a) ′ to (c) ′). .

With respect to the above, since the information format giving these values d and s is essentially the same as the conventional example, the description thereof will be omitted here. As described above, according to the present embodiment, the number of signal lines to be externally given to the display unit 81 to indicate the date format is reduced from “6” in the conventional example to “4”. In addition, both formats of the date to be imprinted on the frames shot in the standard mode and the full mode are surely displayed.

Therefore, the degree of freedom in mounting is expanded, the required number of bits of the output port of the control unit 82 is reduced, and the surplus output port can be utilized for higher functionality and the like. In the embodiment described above,
Although the display 81 is configured without including the segment indicating the day value forming the date, the present invention is not limited to such a configuration. For example, the permutation indicating the date format is “year / month / day”. In the case of being limited to three types, “month day year” and “date year”, it is possible to place only the segment indicating the month and it is necessary to make sure that such a format can be identified. Even if the above-mentioned permutation is not limited to three, a segment that individually indicates any two of the year, month, and day may be arranged.

Further, in each of the above-described embodiments, only the time is displayed in the state where the time is displayed as in the full mode, but the present invention is not limited to such a display mode. The date and time is 12 June 1, 1995.
As with the character string “1.12: 00” in the case of “hour 00”, the date can also be displayed together by using the extra segment located on the left side of the display surface.

FIG. 12 is a diagram showing a mode switching procedure in this embodiment. Hereinafter, the operation of this embodiment corresponding to the invention described in claim 2 will be described with reference to FIGS. 9, 12 and 4. The control unit 82 has initial values M0, d0, and d0, which should be set in the mode register 51, the date format register 52, and the status register 53 at the time of startup.
s0 is given in advance, and in the initialization process, these initial values are set in the corresponding registers. For the sake of simplicity, the initial values M0, d0, and s0 are “0” indicating the standard mode, “0” indicating that the date display order is “date”, and “date”. It is assumed that “1” indicating that the date should be displayed on the display unit 123, the month and date display unit 124, and the year / minute display unit 125.

In addition, the control unit 82 uses the switch 12 in the process of the regular processing after the above-mentioned initialization is completed.
While monitoring the states of the contacts 1 and 43 at a predetermined frequency, the length of the period in which these contacts are continuously closed is measured, and the following processing is performed according to the result of the monitoring and measurement. When the contact of the switch 121 is closed for a period of less than 2 seconds, the control unit 82 changes the value s of the status register 53 to “2” → “0” → “1” each time the event occurs. → "2"
.. and the display control processing adapted to the result of the update is activated as appropriate. Therefore, the information displayed on the year / month / day display section 123, the month / date / time display section 124, the year / day / minute display section 125, and the hour / minute mode display section 126 is “time” each time such a switch 121 is operated. → "None" → "Date" → "Time" ... Can be switched cyclically (Fig. 12).

When the contact of the switch 43 is closed for a period of 2 seconds or more, the control unit 82 sets the value d of the date format register 52 to "1" every time the event occurs.
→ "2" → "0" → "1" ... Is updated cyclically, and display control processing adapted to the result of the update is activated as appropriate. Therefore, the date format is cyclically switched to "month / day / year" → "date / year" → "year / month / day" → "month / day / year" ... each time the switch 43 is operated (FIG. 12).

The series of processes performed by the control unit 82 in this manner can be similarly performed by the control unit 41 in the embodiment shown in FIGS. 3 and 7, but this is omitted here for simplicity. A description of similar processing will be omitted. Further, when the contact of the switch 121 is closed for a period of 2 seconds or more, the control unit 82 causes the value s of the state register 53 at that time to be “0”, “1”,
Whichever value is "2", the value is saved in a predetermined storage area and then set to "3 (indicating that the correction target is the value of" year ")" (FIG. 12) and the date And the time correction process is started. In the process of such correction process,
The control unit 82 monitors the states of the contacts of the switches 121 and 43 at a predetermined frequency, and every time the contacts of the switch 121 are closed, the value s of the state register is “4” → “5” → “6” →
The value is sequentially updated to "7" (FIG. 12), and the value is returned to the value previously saved (FIG. 12). In addition, in the process of such correction processing, the control unit 82, every time the contact of the switch 43 is closed for a period of less than 2 seconds, the correction target indicated by the value s of the state register (“year , "Month", "day", "hour", or "minute") is incremented (decremented) to set the value to a desired value. The display control process for displaying the result of such correction on the display 81 is basically the same as that of the conventional example, and therefore the description thereof is omitted here.

As described above, according to the present embodiment, the display 8
Operation to switch the information to be displayed in 1 and that information,
Since it is possible to select and perform the operation of switching the date format in any order, it is possible to perform a large number of operations as compared with the conventional example in which these operations are performed in series by repeating specific operations. The nature is enhanced.

In each of the above-described embodiments, there is a mode in which both the date and the time are not displayed, as in the case where the value s of the status register 53 is "0". Not limited to such a mode configuration, for example, either the date or the time is always displayed except during calibration, or specific character information or graphic information is switched and displayed according to the date or time. The same can be applied to configurations of modes in which they are displayed or combined and displayed.
