Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device for shooting data of a camera.

[0002]

2. Description of the Related Art Conventionally, there has been a device for storing photographed data, but there has been a problem that when a large number of films are photographed and the data is stored, the difference between new data and old data cannot be recognized.

[0003]

In the conventional data memory card, it is attempted to distinguish between the new data and the old data by displaying a special display, but it cannot be said that the photographer can easily understand. ..

[0004]

According to the present invention, storage means for storing photographed data, writing means for designating and storing a specific location of the storage means, and erasing data by designating a specific location of the storage means. Erasing means, detecting means for detecting that a new film has been mounted, and when the detecting means determines that the film is intact, only the writing means is operated to write data, and the detecting means mounts a new film. When it is determined that the data is erased by the erasing means, the writing means writes the data.

[0005]

According to the above construction, when the new film is inserted, the control means erases the old data in advance and then writes the new data. I know if it's a film.

[0006]

EXAMPLE An example of the present invention will be described below. FIG. 1 shows the circuit configuration of this embodiment. The control means (1) is composed of a microcomputer, receives information from switches and photometric means, shutter speed TVC and aperture value A.
Calculate VC and control AE means. It also creates display data and controls the display means. The film detection means (2) sends the ISO sensitivity SV of the film to the control means.
It also detects the presence or absence of film and the end of winding. AE
The means (3) performs exposure based on AVC and TVC calculated by the control means. The lens (4) sends lens information to the control means (1). The photometric means (5) measures the brightness of the subject for exposure control and sends the value to the control means (1). The film driving means (6) winds and rewinds the film. The display means (7) displays the data from the control means (1). Storage means (8) is EEPROM
It is composed of M and the like, and stores and erases data under the control of the control means (1).

The switch S1 starts the exposure calculation. The switch S2 performs release. The switch S3 switches between a mode in which no data is stored and a mode in which data is stored. The switches S4 and S5 switch the exposure mode of the camera. The switch S6 is used to set a data storage area. The key ADJ switches between a mode for displaying shooting data and a shooting ready state. The key CD changes the display item in the mode for displaying data. Key UP, DOW
N is a mode for displaying data and changes the number of display frames.

2 to 5 show the flow of camera control according to this embodiment. First, in FIG. 2, the film storage area FA of the storage means is initialized to 1 in # 5. FA is 1
5 to 5, and the areas for storing the data of the storage means are divided as shown in FIG. Each area can store data for 40 frames. In step # 10, the switch S1 is viewed to determine whether to start the shooting operation of the camera. Here, if S1 is ON, the photographing operation is started. On the other hand, if S1 is OFF, it waits until S1 is turned ON. #
20, data required for control, specifically, BV (brightness of the subject) from the photometric means, SV from the film detection means
V (film sensitivity), AV0Z from lens (open aperture of lens), ZFZ (focal length of lens), and switch data S1, S2, S3, S4, S5 are obtained.

In step # 30, the main subject exposure amount EVS is calculated from the main subject brightness BV and the film sensitivity SV. This value is used to calculate the aperture value and shutter speed that will be controlled in later processing. In step # 40, the shooting aperture AVC and the shutter speed TVC are calculated to determine the exposure value of the camera. Here, one of the four exposure modes shown in Table 1 below is calculated according to the states of the switches S4 and S5.

[0010]

[Table 1]

At step # 50, the switch S3 is looked at in order to switch whether to store the data or not. here,
If S3 is OFF, shooting aperture AVC and shutter speed T
Go to # 670 in FIG. 3 to expose with VC. on the other hand,
If S3 is ON, the data storage process is performed after # 70. Next, at # 60, the switch ADJ is looked at to determine whether or not the mode for displaying the stored data is entered.
Here, if ADJ is OFF, the process proceeds to step # 670 in FIG. 3 in order to perform exposure with the shooting diaphragm AVC and the shutter speed TVC. On the other hand, if ADJ is ON, data storage processing is performed after # 70.

In step # 70, a process for initializing the data display process is performed. An example of the data display is shown in FIG.
There are 1 to 6 PFs. This is set to PF = FA in order to display from the film area FA in which data is currently stored. The PF displays the following. PF = 1 Display data for film area 1 PF = 2 Display data for film area 2 PF = 3 Display data for film area 3 PF = 4 Display data for film area 4 PF = 5 Release without film Display time data (area 5) PF = 6 Select film storage area and display data reset.

P1 is a display item of data, and P1 = 1
Initialize to. The display items are as follows. P1 = 1 film area, ISO value display P1 = 2 control aperture AV, control shutter speed TV, exposure mode display P1 = 3 exposure correction value display P1 = 4 open aperture AV0Z, lens focal length ZFZ display P2 Is the number of film frames to be displayed and is from 1 to 40.

WFA is an area for selecting a film storage area and is initialized to WFA = FA. The display items are as follows. WFA = 1 Change to store data in film area 1 WFA = 2 Change to store data in film area 2 WFA = 3 Change to store data in film area 3 WFA = 4 Data in film area 4 Change to memorize WFA = 5 Erase all data.

At step # 80, the key ADJ is viewed to enter the mode for displaying the stored data. If ADJ is OFF, the stored data display mode after # 140 (FIGS. 4 and 5) is entered. At # 90, the key ADJ is looked at in order to exit the stored data display mode once entered. # 1 if ADJ is ON
After 10, the process goes out of the stored data display mode. #
At 100, it is determined whether or not PF = 6 in order to perform the process of selecting the film storage area. If PF = 6, then # 11
Area selection processing is performed at 0 and # 120. At # 110, the WFA is viewed for processing the film storage area. If WFA = 5, the process goes to step # 120 to erase all the data stored in the storage means. On the other hand, if WFA = 5 is not satisfied, the storage area FA is changed to FA = WFA in # 130.

In FIG. 4, in # 140, the key CD is viewed to change the display item. If the CD is ON, # 15
If it is OFF, it goes to the processing from # 175. In # 150, to change the display item, P1 =
Let P1 + 1. In order to return the item display to the film area and ISO value display, if P1 ≧ 5 in # 160 and # 170, P1 = 1 is set, and then the process goes to # 360 in FIG.

At step # 175, the switch S6 is viewed to determine whether or not the film storage area is set.
If S6 is ON, PF = 6 is set, the area setting process is performed in # 177, and then the process proceeds to # 360. On the other hand, if OFF, go to # 180.

In # 180, the PF is used to either change the display data or the storage area.
I see. If PF = 6, go to # 270. If PF = 6 is not satisfied, the process proceeds to the display change process from # 190. # 190
Now look at the UP key to change the display. If it is ON, # 2
00, go to # 270 if OFF. In order to change the display film area PF when P1 = 1 and to change the number of display film frames when P1 = 1, the value of P1 is determined in # 200. Here, if P1 = 1, in order to change the display film area, PF = PF + in # 210.
Set to 1. Since PF = 1 to 6, in # 220 and # 230, if PF ≧ 7, if PF = 1, then go to # 360.
On the other hand, if P1 = 1 is not set, P2 = P2 + 1 is set in # 240 in order to change the display film frame. Since the number of film frames is up to 40 frames (ie P2 = 1-40), # 2
In the case of 50 and # 260, if P2 ≧ 41, P2 = 1 is set and then # 360 is executed.

In # 270, the PF is used to either change the display data or the storage area.
I see. If PF = 6, the process goes to # 360 in FIG. 5, and if PF = 6, the process goes to the display change process from # 280. At # 280, the DOWN key is viewed for display change. If the DOWN key is ON, go to # 290 and OF
If F, go to # 360. When P1 = 1, the display film area PF is changed, and when P1 = 1 is not set, the number of display film frames is changed. Therefore, the value of P1 is determined in # 290. Here, if P1 = 1, PF = PF-1 is set in # 300 in order to change the display film area. PF =
Since 1 to 6, in # 310 and # 320, if PF ≦ 0, then P
After setting F = 6, go to # 360. On the other hand, if P1 is not 1, P in # 330 to change the display film frame
2 = P2-1. There are up to 40 film frames (that is, P2 = 1-40), so for # 340 and # 350, P
If 2 ≦ 0, set P2 = 40 and then go to # 360.

In FIG. 5, in # 360 to # 440, display data is created to display the shooting data. First, in # 360, the PF is viewed to either change the display data or the storage area. PF
= 6, go to # 460. If PF = 6, go to # 36.
Go to the process of creating display data from 5. Where PF =
If not 6, the photographing data of the RL frame of the currently designated film area PF is read from the storage means in # 365. When P1 = 1, the film area P is set at # 380.
The display data of the film sensitivity of F and area PF is made. P
When 1 = 2, the display data of the photographic aperture AV, the photographic shutter speed TV, and the exposure mode of P2 frames in the film area PF are created in # 400. When P1 = 3, the display data of the exposure correction value of the P2 frame of the film area PF is created in # 420. When P1 = 4, P in film area PF at # 440
Create display data for 2 frames of lens focal length and open aperture. Next, in # 450, the above # 380, # 400, and # 4.
The display data created in # 20 and # 440 is output to the display means.

Since # 460 to # 540 are PF = 6, the flow is for changing the film storage area or erasing all data. In # 460, the UP key is viewed to change the storage area. If the UP key is ON, WFA = WFA + 1 in # 470 to advance the storage area.
And # 48 to limit between WFA = 1-5
In 0 and # 490, if WFA ≧ 6, WFA = 1 is set and then # 540 is executed. On the other hand, if the UP key is OFF, look at the DOWN key at # 500 to change the storage area. Since the DOWN key is ON, in # 510, WFA = WFA-1 is set to return the storage area. WFA = 1 ~
WFA in # 520 and # 530 to limit between 5
If ≦ 0, set WFA = 5 and then go to # 540. # 5
In 40, display data for film storage area selection is created,
Output to display means. Then, it returns to # 90 of FIG.

In FIG. 3, # 550 to # 730 are flows for processing data storage. In step # 550, the switch S2 is viewed for the exposure operation. If S2 is ON, at S560, the S3 switch is looked at to determine whether to store data. If S2 is OFF, the process returns to # 10 in FIG. Here, if S3 is ON, # 57
A process of switching the area to be stored with 0 depending on the presence or absence of the film is performed. First, if there is a film, the number of shots RL is counted and RL =
Let RL + 1. If the number of shots RL ≧ 41, data is not stored, so the value of RL is determined in # 590 and RL <4
If it is 1, the process proceeds from # 600 to the data storage process. # 60
At 0, if the number of shots RL = 1, old data in the storage area is erased and new data is stored,
Determine the value of RL. If RL = 1, it means that it is the first image to be photographed, so that the old data in the storage area FA of the storage means is erased in # 610. If RL = 1, go to # 620. In # 620, the shooting data is stored in the RL frame of the storage area FA.

If there is no film, the number of shots RL is counted in order to store the shot data in # 630, and RL =
Let RL + 1. RL for 640 and # 650
If ≧ 41, RL = 1 is set, and if RL <41, the process directly goes to # 660. In # 660, since there is no film at this time, the photographed data is stored in the storage area FA = 5 of the storage means RL
Store in the frame.

When the process of storing the photographed data in # 620 and # 660 is completed, in # 670, the exposure operation is performed based on the AVC and TVC.
Is output. In step # 680, the film is wound to take the next frame. In step # 690, the switch S3 is viewed for processing only in the data storage mode. # 700
In order to change the storage area when the film is all wound up, it is judged whether the film is over. S
If 3 is ON and the film is finished, # 7
In No. 10, since the film is all wound up, it is necessary to advance the film area and store the FA from the first frame.
= FA + 1 and RL = 0. Since the film is gone, rewind the film at # 715. Since the storage film areas are from 1 to 4, the FA value is determined in # 720 and # 730 to warn when the area returns from 4 to 1. Here, if FA ≧ 5, FA = 1 is set and the data of the warning display is output to the display means, and then the process goes to # 10 to continue the control. An example of the warning display is shown in FIG.

[0025]

As described above, according to the present invention, it is possible to easily determine which film the data belongs to even when many films are photographed.
