Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a data imprinting device for a camera.

[Prior Art] Conventionally, in a data imprinting device for a camera, when correcting the time according to the time difference, the time is corrected by manual operation.

[Problems to be Solved by the Invention] In the conventional camera data imprinting device described above, troublesome operations are required when correcting the time according to the time difference. Therefore, by improving this, for example, an area code is determined according to the country, time difference data to be corrected according to this area code is held, and the time is corrected based on this correction data. Just add it to the camera's data imprinting device.

However, when such a time difference correction function is added, there is a drawback that when the time difference is corrected and only the time changes without changing the date, the operator cannot clearly confirm that the time difference has been corrected. .

In order to improve this drawback, it is conceivable to constantly display both the date and time on the display section of the data imprinting device of the camera. However, if the setting is to imprint only the date, the time will also be displayed, even though the time is not actually imprinted, giving the impression that the time is also imprinted. There was fear. Also,
In order to display both the date and time on the display portion in this way, the area of the display portion is enlarged, which has the disadvantage that the camera cannot be miniaturized.

[Means for Solving the Problems] The camera data imprinting device of the present invention includes a time difference changing means for correcting the date and time measured by the calendar means in accordance with a change in time difference, and a time difference changing means for adjusting the time difference by the time difference changing means. a detecting means for detecting that the date displayed on the display means is not changed due to the change; and a detecting means for detecting that the date displayed on the display means is not changed by the change; and a detecting means for detecting that the date is not changed as a result of the change; and time difference change display means for displaying the change on the display means.

Furthermore, the fact that the time difference has been changed by the time difference change display means is indicated by displaying the time measured after the time difference change on the display means for at least a predetermined period of time.

[Operation] When it is detected that the year, month, and day displayed on the display means are not changed due to the time difference change by the time difference change means, the display means displays for a predetermined time that the time has changed due to the time difference change. This allows you to confirm that the time difference has been corrected.

Further, the fact that the time difference has been changed may be indicated by displaying on the display means the time measured after the time difference has been changed, at least for a predetermined period of time.

[Example] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a data imprinting device for a camera according to the present invention. In FIG. 1, C1 is a control circuit for imprinting the date, and in addition to well-known parts such as a clock circuit (calendar means) 1 a display control circuit and an imprint control circuit (not shown), it also includes a data bank for correcting time differences. have. C2 is a camera control circuit that controls the camera;
Ll is an external display device (display means) that externally displays at least one of the date and time, and L2 is an imprint device that imprints onto the film.

In addition to ordinary silver halide cameras, for example, in electronic cameras such as video cameras and still video cameras (SVC), this corresponds to a recording device on a recording medium.

Switches SWI and SW2 are time difference
(rence) This is a correction code input switch, and the time difference correction code is shown as a two-digit number corresponding to the city of the world. For example, Tokyo is set to 21, Northeast is set to 20, Los Angeles is set to 4, etc. According to the selected time difference correction code, the time difference is automatically corrected based on a map stored in advance in the control circuit C1. The correction code input switch SWI operates the code 10 digit, and SW2 operates the code 1 digit, and each time the switch is pressed, the number changes by 1.

Note that the method of inputting information to correct the time difference is not limited to the input method using the time difference correction code described above, but you can also enter the city name or place name directly, display a world map, There are various input methods, such as pointing to a point on a map and entering the location.
It is similar to the so-called conventional world clock. In any case, the time difference is corrected according to the input information, and the year, month, day, and time measured by the clock device change. At the same time, the calendar display changes accordingly.

sw3 is daylight saving time.
This is a daylight saving time setting switch for setting (time).

SW4 is a mode changeover switch, and each time the switch is pressed, the display mode changes in the order of five display modes: year, month, date, January, day, year, year, month, year, day, hour, minute, and off (off). Note that in the following, the calendar display refers to the display of the year, month, day, January, day, 9, year, month, and year, and the time display refers to the display of the date, hour, and minute. Further, the display mode is not limited to this, and it goes without saying that other display modes, such as displaying hours, minutes, and seconds, may be used.

SW5 is a select switch, and by pressing the switch, a correction mode is selected and the digit to be corrected is changed one by one.

SW6 is a correction switch, and select switch SW5
The numerical value of the selected digit changes by one in response to the depression of the correction switch SW6.

FIG. 2 is an external view showing the display section of the external display device fLL in FIG. 1. 1 is the time difference correction code display section, 2 is the daylight saving time display section indicating that it is daylight saving time, 3 is the imprinting completion display section, and 4 is the display section of a conventional date imprinting device with a function to change the order of the year, month, and day. It is similar to that.

Figure 3 shows the calendar display state on the display section of external display device L1 when Tokyo (time difference code 21) is selected as the time difference correction code. Figure 4 shows the state of the calendar display on the display section of external display device L1 when the calendar display is switched from the calendar display to the time display in Figure 3. The operation when switching from the state shown in FIG. 3 to the state shown in FIG. 4, which shows the display of Step S2) to determine whether it is in month/day mode or not;
If it is "Y", that is, the date mode, change the display mode to the month, day, year mode, which is the display mode immediately after this date mode among the five display modes described above (
Step S7).

If it is "N", that is, the month, day, and day mode, it is determined whether or not it is the month, day, and year mode. The display mode is changed to month/year mode (step S7). If "N", that is, it is not the month-day-year mode, it is determined whether it is the day-month-year mode (step S4), hereinafter,
The display mode is determined and changed in the same way as above (
Steps 85-S7).

Next, in the case of the calendar display shown in Figure 3, let us consider the case where the time difference correction code is Northeast (time difference correction code 20), which has a one-hour time difference with Tokyo. If the display shown in the figure is displayed and the display mode remains unchanged as a calendar display, the user will not be able to confirm the correction even if the time difference is corrected, and the time difference will not be corrected properly. In this case, the time difference correction code is manually entered (step 5), as shown in the flowchart in Figure 7.
ll) = time difference calculation and correction are performed (step 512)
Therefore, according to the present invention, after the time difference correction operation, the display as shown in FIG. 8 is displayed for a predetermined period of time. In other words, in the date mode shown in Figure 3, if you enter the northeast time difference correction code and perform the time difference adjustment operation as described above, the calendar display will be replaced by the calendar display shown in Figure 3 for a predetermined period of time, as shown in Figure 8. The date and time are displayed in the display mode.

This allows the operator to reliably confirm that the time difference has been corrected. After being displayed in the state shown in FIG. 8 for a predetermined period of time, the display mode is automatically switched to the display mode before the correction operation, that is, the date display mode shown in FIG. Also, if the display mode before the corrective action was day, month, year,
Return to day/month/year display mode. This operation will be explained with reference to the flowchart shown in FIG. First, a time difference correction code is input (step S21), time difference is calculated and corrected based on the input time difference correction code (step 522), and it is determined whether the current display mode is the date, hour, and minute mode (step 523). ), if it is "Y", that is, the date, hour, and minute mode, it displays in the current display mode (step S27), and if it is "N", that is, it is not the date, hour, and minute mode, it is determined whether or not it is currently in the off mode (step 524);
If "Y", that is, off mode, return, r N
, 1. That is, if it is not the off mode, it changes to the date, hour, and minute mode and displays for a predetermined time (step S25).After this, it returns to the original display mode (step 526).

(Figure 0 shows another example, and in Figure 3, it shows the case where the time difference correction code is selected as Los Angeles. In Los Angeles, it is 5:10 p.m. of the previous day, so the date part of the calendar display changes. In addition, in this embodiment, the date arrangement is automatically switched to the arrangement most customarily used by residents of the city corresponding to the selected time difference correction code. , it can be seen that the time difference correction operation has been reliably carried out.Furthermore, FIG. 11 shows a case where, in this embodiment, the date, hour, and minute are displayed instead of the calendar display for a predetermined time, as in the above-mentioned embodiment. These operations are shown in the 12th display.
This will be explained with reference to the flowchart shown in the figure. Step S3
1 to S35 and S36 are steps S21 to S in FIG.
25 and S27, and the explanation will be omitted. After the date and time are displayed for a predetermined time in step S35, it is determined whether the original display mode matches the customary arrangement of cities corresponding to the time difference correction code input in step S31 (step 537). , "Y", that is, if it matches the conventional arrangement, return to the original display and proceed to step S.
39>, "NJ", that is, if it does not match the customary layout, the display mode is switched to a display mode according to the customary layout corresponding to the city (step 538).

In addition, in the above-mentioned embodiment, due to a change in time difference,
Although the date, hour, and minute are always displayed for a predetermined period of time, the mode may be switched to the date, hour, and minute mode for a predetermined period of time only if the year, month, and day are not changed even if the time difference is changed.

Furthermore, in the above-described embodiment, the calendar display section displays the date, hour, and minute for a predetermined period of time according to the time difference correction; however, the calendar display section is not limited to this; The mode may be automatically switched to the date, hour, and minute mode, and the calendar display may be returned to immediately upon completion of the correction operation, or the calendar display may be returned to the calendar display after a predetermined period of time has elapsed.

Note that if the next time difference correction operation is performed before the predetermined time period for displaying the date, hour, and minute mode has elapsed, it is desirable that the time difference correction be given priority.

[Effects of the Invention] As explained above, according to the camera data imprinting device of the present invention, when it is detected that the date displayed on the display means is not changed by changing the time difference by the time difference changing means, By displaying on the display means that the time has changed due to the time difference change for a predetermined period of time, it is possible to confirm that the time difference correction has been reliably made. Furthermore, the fact that the time difference has been changed may be indicated by displaying on the display means the time measured after the time difference has been changed, at least for a predetermined period of time. Therefore, it is possible to confirm that the time difference has been changed or corrected.

In addition, unlike the case where both the date and time are always displayed on the display part of the data imprinting device of the camera, there is no risk of giving a misunderstanding that even the time is imprinted, and it is possible to display both the date and time on the display part of the data imprinting device of the camera. Since there is no need to display it on the display section, there is no need to enlarge the area of the display section, which has the advantage that miniaturization of the camera is not hindered, and there is no need to increase the cost.
