Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a camera having a function of imprinting date, time, photographing location, etc. (hereinafter referred to as data) onto a photosensitive film (hereinafter referred to as film).

With advances in electronics technology, cameras have come to be provided with various useful additional functions.

One of these is the function of superimposing data on images of landscapes, people, etc., and is particularly useful for family records, travel photographs, and the like.

FIG. 2 is a conceptual diagram of a conventional camera with a data imprinting function. In the figure, 1 is a clock generation circuit. Usually, the time at that time is sampled by the controller 4, and the current time or date is displayed on a monitor display 9 attached to the back cover. For example, if the date and time needs to be corrected when replacing batteries or traveling abroad, press the clock correction key 3 while looking at the monitor display 9, and the clock correction circuit 2 will activate to set the date and time to be corrected. After the date and time are set, the corrected date and time will continue to be displayed on the monitor display. Enter the data you want to keep on the film, such as the name of the place you are traveling to and other necessary information, as shown below. First, the user presses and inputs the data key 7 while looking at the data displayed on the monitor display 9, and the necessary data is sequentially stored from the data input circuit board to the data memory 5. Then, when the shutter 11 is pressed to take a photograph of a person, landscape, etc., in the camera of this specific example, data is first sent from the data memory 5 to the LlCD driver 8 under the control of the controller 4 in the order in which it was input. , LKDlo emits light and data is imprinted onto the film. When all the data is output, the controller 4 sends a time signal from the clock circuit 1 if a date signal is needed. It is sent to the D driver 8, LIliDlo emits light, and is imprinted onto the film. In this way, place names, dates, times, etc. can be imprinted as needed, allowing the film to be used even more effectively.

Conventional cameras with data imprinting function, like this example,
While it is convenient that the data can be imprinted onto the film,
It has many drawbacks as listed below. One of them is that conventional cameras with data imprinting function usually display the date and time on an external monitor display, which serves as a kind of clock, but when traveling overseas, it is necessary to correct the time difference. When the need arises, the time must be adjusted each time by inputting a key switch, which is a waste of time. Furthermore, if it becomes necessary to imprint a place name or the like onto the film, the data must also be entered using a key switch, which is a redundant effort and there is a risk of missing a photo opportunity. Another drawback is that incorrect data may be imprinted onto the film as a result of repeated input changes. If incorrect data is imprinted, not only will the data imprint be worthless, but the photograph itself will have no value as a memorial or record.

Another way to set the time to the local time at your destination is to set the abbreviations of place names in advance, display some on the external monitor display, and set the local time by key operation. There are drawbacks.

One of them is that the abbreviations of place names are displayed on the display, which limits the number of place names that can be set in advance due to the size of the display. Another disadvantage is that displaying the abbreviations of place names on the display increases the cost of the display. Yet another drawback is that due to the abbreviation (
(TKO→TOKYO) If you don't get used to it, you won't know which place name it's referring to, and you won't be able to use it.

The present invention focuses on this drawback, and by inputting the place name,
To provide a camera with a data imprinting function that automatically changes the date and time and is easy to use and can be used by anyone.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a conceptual diagram of a camera with a data imprinting function according to the present invention.

The biggest difference between the present invention and conventional cameras with data imprinting function is that it is equipped with a circuit for identifying input place names.
Furthermore, a time correction circuit is installed, so that when a place name is entered, the built-in clock is automatically corrected to the local date and time.

In FIG. 1, 30 is a data key for manual operation. Data is entered while checking on the monitor display 22. For example, in the case of TOKYO in this example, when T is first input as data 30, the data input circuit 27 sends it as a digital signal corresponding to T to the data memory circuit 26 and stores it. When T is confirmed on the monitor display 22, 0 is similarly stored in the data memory circuit 26. Then, KYO is sequentially memorized and waits until the data input is completed and the shutter SW 20 is pressed. When the data input is completed, the data discrimination circuit compares the data with the place names of countries around the world currently stored in the data memory circuit, determines which place name has been input, and sends the data to the time correction circuit 24. At this time, the time correction circuit calculates the difference between GuiJ Nitsuji standard time and the time of the input place name,
A correction signal for the difference is sent to the clock circuit 23. For example, in this specific example, since TOKYO is input, the difference from Greenwich Mean Time is 9 hours, meaning that TOKYO is 9 hours ahead. The revised date and time is displayed on the monitor display 22. When the shutter SW 20 is pressed to take a picture of a landscape, a person, etc., the data memory circuit 26 is first activated by the controller 21.
The data already stored in is recalled. In this specific example, since TOKYO is input, it is sent to LED Drino-28 in order starting with T and ending with O.
1] 1iD29 emits light. When all the place names to be imprinted on the film have been emitted, the date is sent out at predetermined intervals, and I, 11iD2
9, it emits light and is imprinted on the film. The date at this time has already been automatically changed by the power of place names. If it is desired to further imprint the time on the film, the time is also sent to the LmD, which emits light and is imprinted onto the film.

In this way, after the input place name, the date, time, etc. are neatly lined up and imprinted onto the film. Note that data other than place names, such as people's names, are processed by the data discrimination circuit 2.
5, and no time correction is made. At this time,
Needless to say, the place name has already been entered.

As explained above, the camera with the data imprinting function according to the present invention automatically adjusts the time of the built-in clock by inputting data, and therefore has the following advantages.

(1) When a place name is entered, the date and time are automatically changed to the local time, so there is no tedious input and it is easy to use.

(2) Input errors will be eliminated, and the reliability of the data imprinted on the film will be increased, and the value of the film itself will also be improved.

(3) Anyone can input local place names easily and without error.

(4) Once the standard time is set, there is no need to adjust the time, so the switch for adjusting the time can be simplified, and the structure of the camera itself can be simplified and made smaller.

In this embodiment, the time is automatically corrected by providing a data discrimination circuit and a one-hour correction circuit, but the present invention is not limited to this. If the controller has a margin, the controller determines the data.

It may also have functions such as time correction. This further simplifies the structure, resulting in a smaller, lighter, and less expensive camera with a data imprint function.

As described above, in the camera with data imprinting function according to the present invention, the time of the built-in clock is automatically adjusted by inputting the place name of the destination, so anyone can use it easily without any training. , provides a compact, lightweight, and easy-to-handle camera with a data imprint function□
