DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for setting numerical data such as time and date in a camera.

[0002]

2. Description of the Related Art Conventionally, in cameras having a function of displaying numerical data such as time and date, numerical data such as time and date have been used.
In setting the data, a set key and a shift key are used. In other words, by operating the set key, it becomes possible to change the numerical data. By operating the shift key in this state, the type of data to be changed is selected. For example, each time the shift key is operated, the type of data is sequentially moved and selected, such as "year → month → hour → minute → end". When the set key is operated in a state where the type of data to be set is selected, the data is set.
The value for the data increases.

[0003]

However, in the above-mentioned conventional apparatus, since the numerical value is fed only in one direction (for example, in the + direction), for example, when there is data of 0 to 59 as in the case of a clock. However, if the data is excessive during setting, the shift key must be operated to make another round, which is very inconvenient.

It is also conceivable to add a dedicated operation key for performing reverse numerical feed, but there is a drawback that the cost is increased. The present invention has been made in view of such circumstances, and has as its object to enable setting of numerical data without providing a special operation unit for increasing or decreasing numerical values in a camera.

[0005]

To achieve the above object, a numerical data setting apparatus in a camera according to the present invention comprises:
A zooming operation unit for performing a zooming operation, a selection operation unit for selecting a type of numerical data to be set, and a numerical value of the selected numerical data is increased or decreased by operating the zooming operation unit. And control means.

[0006]

The type of numerical data to be set is selected by the selection operation unit, and the numerical value of the selected numerical data is increased or decreased by operating the zoom operation unit.

0:25), date (October 12, 1992) and the like are often displayed, but such information can be set using as few keys as possible. As shown in FIG. 3B, the mode of the information to be set is "time of clock" and "minute of clock" by operating a setting / shift key which is a selection operation unit provided in the camera body. , "Year", "month",
The date is set in the order of “day”, and in each setting mode,
By the operation of the E key, the information is incremented (increased) by one, and by the WIDE key operation, the information is decremented (decreased) by one. Thus, time and date data
When the data is set, the TELE or WIDE operation in the camera mode is not performed.

Next, the operation key input processing will be described with reference to FIG. The following processing is performed by the system control circuit 13 which is a control means. First, the setting mode
Is determined (step S411), and if set, it is determined whether the setting / shift key of FIG. 4 is operated (step S412). here,
If it has been operated, the set digit counter is incremented by 1 (step S413), and if it has not been operated, it is determined whether or not the set digit counter is END (step S414). Here, if it is the end, the set digit counter is set to the initial value (step S415), and the process returns to the main routine. If the set digit counter is not END, it is determined whether or not the TELE key of the camera is turned on. (Step S41
6). If the TELE key has been turned ON, the data in the RAM corresponding to the set digit counter is incremented by 1 (step S417), the process returns to the main routine, and if the TELE key has not been turned ON, It is determined whether the WIDE key of the camera has been turned ON (step S418). If the WIDE key has been turned ON, the RAM data corresponding to the set digit counter is decremented by 1 (step S419).
If the WIDE key has not been turned ON, the routine returns to the main routine.

If it is determined in step S411 that the setting mode is not the setting mode, it is determined whether or not the setting / shift key is operated (step S420). If it is ON, the mode conversion flag is set to ON. (Step S42
1) Returning to the main routine, if the ON operation has not been performed, it is determined whether or not the TELE key of the camera has been operated ON (step S422). At this time, if the ON operation has been performed, the TELE operation request flag of the camera is turned ON (step S423), and the process returns to the main routine. If the TELE key is not ON, the WIDE key of the camera is turned ON. It is determined whether or not it has been performed (step S424). If the ON operation has been performed, the WIDE operation request flag of the camera is turned ON (step S425). If the ON operation has not been performed, the process returns to the main routine.

As described above, according to the numerical data setting device in the camera according to the present embodiment, the information is incremented (increased) by one by the operation of the TELE key.
Since the information is decremented (decreased) by one by operating the IDE key, the numerical data can be set without providing a special operation unit for increasing or decreasing the numerical value. Accordingly, it is possible to reduce the number of operation keys, and thus to reduce the size and cost of the apparatus.
