Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera capable of storing data at the time of photographing.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open Nos. H8-6098 and H6-6-198 disclose a camera capable of storing shutter speed, aperture value, number of frames, and other data at the time of shooting in a memory.
67288 and the like.

[0003] When a moving subject or the like is photographed by a camera, continuous photographing is often performed. Then, in such continuous shooting, similarly to single shooting, setting (preparation) is performed in advance by internal storage of the control circuit.
It is conceivable to sequentially store and hold the obtained photographing data together with an addressing pointer in a memory outside the control circuit after each photographing.

[0004] On the other hand, improving the continuous shooting speed in continuous shooting is an important issue for cameras.

[0005]

However, in order to store (store) data in the memory, a certain amount of processing time is required depending on the processing time for setting the data to be stored and the processing time for actually storing the data in the memory. It takes time. In particular, when storing various types of shooting data,
Processing time also increases. Therefore, as the continuous shooting speed increases, the processing time cannot be ignored. This is also because the access speed of the control circuit to the memory provided outside the control circuit is lower than the access speed to the RAM or the like provided in the control circuit.

[0006] In a photographing sequence, setting and storing photographing data can be performed at once if a collective processing time can be secured. However, at present, once processing is performed, only the processing time is required. There is a problem that the continuous shooting speed is reduced.

On the other hand, by performing the processing at one time,
There is also a merit that there is little inconvenience when a power down or the like occurs during exposure.

Therefore, the present invention provides a camera which can store and hold photographing data without lowering the continuous photographing speed, and further, can select a process for data storage according to a photographing situation. It is intended to provide.

[0009]

In order to achieve the above object, in the camera according to the first aspect of the present invention, a control circuit capable of setting photographic data and a pointer for storing photographic data by internal storage, and this control circuit A storage means provided outside and capable of storing and holding imaging data and a pointer;
The control circuit causes the storage means to store the photographing data set by the control circuit in the storage means after each photographing operation based on the set pointer, and stores the pointer set by the control circuit in: After a plurality of times of photographing, a storage process for storing and holding in the storage means is performed.

That is, instead of performing the storing process of the photographing data and the pointer in the storage means at once after one photographing, the photographing data is not stored at one time after one photographing.
The pointers are respectively taken at the time when the above plural times of photographing are completed. By applying this to the continuous shooting, the time required for the storage process during the continuous shooting is reduced by one to the storage process of the shooting data and the pointer.
This makes it possible to reduce the time required to perform the shooting at one time after each shooting, thereby preventing a decrease in the continuous shooting speed or increasing the continuous shooting speed.

The setting (preparation) of the photographing data and the pointer in the control circuit may be performed before photographing, or the photographing data and the pointer which can be set before photographing are set before photographing, and are set after photographing. The possible photographing data may be performed after each photographing.

In the camera according to the second aspect of the present invention, a control circuit capable of setting photographing data and a pointer for storing photographing data by internal storage, and a control circuit provided outside the control circuit for storing and holding the photographing data and the pointer.

Storage processing for storing the pointer set in the storage means after the end of a plurality of shootings, and storing the shooting data and the pointer set by this control circuit after each shooting. Second means to be stored in the means
Is selectively performed.

That is, as in the first aspect, the storing process of the photographing data and the pointer into the storage means is performed separately after each photographing and after a plurality of photographing ends.
It is possible to select whether to collectively perform after each shooting.

More specifically, a first storage process is performed during continuous shooting, and a second storage process is performed during single shooting. In addition, a first storage process is performed during high-speed continuous shooting, and a second storage process is performed during low-speed continuous shooting. Further, the first storage processing may be performed when the amount of stored imaging data is large, and the second storage processing may be performed when the amount of stored imaging data is small. Furthermore, during continuous shooting, the first storage processing may be performed when priority is given to the continuous shooting speed, and the second storage processing may be performed when data storage retention is prioritized. Further, it may be configured to select whether to perform the first storage processing or the second storage processing in accordance with a user operation.

[0015] This makes it possible to store the photographing data and the like by using an appropriate storage processing method according to the camera situation and the user's intention.

In the camera according to the third aspect of the present invention, a control circuit capable of setting a plurality of photographing data by internal storage and a storage means provided outside the control circuit and capable of storing the photographing data are provided. And causing the control circuit to store, in the storage unit, the photographing data set for the single photographing among the plurality of photographing data set by the control circuit after each photographing. In addition, the control circuit is configured to perform a storage process of storing the photographing data, which is commonly set for the plurality of photographing operations, in the storage unit after the end of the plurality of photographing operations.

That is, the storage processing of a plurality of pieces of photographing data in the storage means is not performed at one time after each photographing, but the photographing data necessary for each photographing is stored every time after one photographing. The photographing data common to a plurality of times of photographing is performed when the above-described plurality of times of photographing ends. By applying this when performing continuous shooting, the time required for the storage process during continuous shooting is reduced as compared with the case where the storage process for all shooting data is performed once after each shooting. This makes it possible to prevent the continuous shooting speed from decreasing or to increase the continuous shooting speed.

The setting (preparation) of a plurality of photographing data in the control circuit may be performed before photographing,
For shooting data and pointers that can be set before shooting, before shooting, and for shooting data that can be set after shooting, 1
You may make it perform after every imaging | photography.

In the camera according to the fourth aspect of the present invention, a control circuit capable of setting a plurality of photographing data by internal storage and a storage means provided outside the control circuit and capable of storing and holding the photographing data are provided. The control circuit causes the storage means to store and hold the photographing data set for the one photographing among the plurality of photographing data set by the control circuit after each photographing; A first storage process for storing storage data in the storage unit after a plurality of times of photographing is completed, the photographing data set in common for the plurality of times of photographing out of the plurality of photographing data by the control circuit; And a second storage process for storing and holding a plurality of imaging data set in the storage means after each single imaging.

That is, as in the third aspect of the invention, a plurality of set photographing data (photographing data set for one photographing and photographing data commonly set for a plurality of photographing) are stored. It is possible to select whether to perform storage processing in the storage means after each photographing operation and after a plurality of photographing operations are divided or performed collectively after each photographing operation.
Specifically, the first storage process is performed during continuous shooting, and the second storage process is performed during single shooting. In addition, a first storage process is performed during high-speed continuous shooting, and a second storage process is performed during low-speed continuous shooting. Further, the first storage processing may be performed when the amount of imaging data is large, and the second storage processing may be performed when the amount of imaging data is small. Furthermore, during continuous shooting, the first storage processing may be performed when priority is given to the continuous shooting speed, and the second storage processing may be performed when data storage retention is prioritized. Further, it may be configured to select whether to perform the first storage processing or the second storage processing in accordance with a user operation.

Thus, it is possible to store and hold photographing data and the like by using an appropriate storage processing method according to the camera situation and the photographer's intention.

At step 110, the film cartridge is loaded. At the next step 120, when it is detected that the back cover has been changed from the open state to the closed state through the back cover open / close switch (not shown), the process proceeds to step 130.

In step 130, a timer waits for a fixed time until the loaded state of the film cartridge is stabilized. Thereafter, in step 140, the film ISO sensitivity and the number of images that can be shot are read from the DX contact state of the cartridge by the DX reading unit 64. Then, Step 1
At 50, the film feeding motor is driven in the normal rotation direction to feed the film in the winding direction.

Next, in step 240, the distance is measured by the distance measuring circuit 55, and the result is used in step 250.
Then, the AF driving circuit 56 is driven to focus the photographing lens.

Next, at step 260, it is determined whether or not the exposure start switch 53 (SW2) is turned on.
If it is not turned on, the process returns to step 200 and the same operation is repeated. If it is turned on, the process proceeds to step 270, where the shooting data is set.

Here, the photographing data refers to a shutter speed, an aperture value, the number of frames, and the like.
These photographing data are stored in the RAM 50a in the control circuit 50.
Refers to the operation of temporarily storing (preparing).

Next, at step 280, a storage pointer is set. Here, the storage pointer refers to step 2
When the photographing data prepared in step 70 is stored in the memory 60, the memory 60 designates a location (address) in which the data is to be stored. RAM 50a inside

Next, the routine proceeds to step 290, where the shutter control circuit 57 and an aperture control circuit (not shown) are operated to perform exposure (photographing) on the film. Upon completion of the film exposure, the process proceeds to step 300, where the photographing data prepared in step 270 is stored in the memory 60 based on the pointer prepared in step 280.

When the process of storing the photographing data in the memory 60 is completed, the process proceeds to step 310, in which the film feeding motor 59 is rotated forward to start film winding. Subsequently, in step 320, the perforation is detected by the photo reflector 7, and when the feeding of one frame is completed, in step 330, the film feeding motor 5 is turned on.
In step 340, the number of frames (photographed frames) is counted up by one.

In the next step 350, it is determined whether or not continuous shooting is to be performed. If continuous shooting is to be performed, the process returns to step 270 to continue shooting. If the continuous shooting is not performed (including the case where the continuous shooting is completed), the process proceeds to step 360,
The storage pointer is stored in the memory 60.

When the process of storing the storage pointer in the memory 60 is completed, in the next step 370, it is determined whether or not the number of frames has exceeded the number of recordable images read in step 140.
Return to 0.

On the other hand, if the number exceeds the allowable number, the process proceeds to step 600, in which the film feeding motor 59 is reversed to start feeding the film in the rewinding direction. Each time one frame of perforation is detected in step 610, the number of frames is counted down by one in the next step 620, and in the following step 630,
The same operation is repeated until the number of frames becomes zero.

When the number of frames becomes 0, step 640
Wait for the leading end of the film to pass through the position of the photo-reflector 7, wait for a certain time by a timer in step 650 to wait for the film to be caught in the cartridge, and then in step 660, 59 is stopped, and the film rewinding is terminated.

Thereafter, when it is detected in step 670 that the back cover opening / closing switch is changed from the closed state to the open state, in step 680, the process waits until the cartridge is removed, and ends a series of photographing sequences.

When the high-speed continuous shooting mode is set, the first state is determined, and when the low-speed continuous shooting mode is set, the second state is determined. When the amount of data to be stored is large, the first state is determined, and when the amount of data is small, the second state is determined. Further, the first state and the second state may be manually set by a user operation such as a process selection switch (not shown).

Then, after executing step 340 ',
In steps 262, 264, 266, and 268, the setting (preparation) of the shooting data and the storage pointer in the RAM 50a and the storage of the set shooting data and the storage pointer in the memory 60 are collectively performed.

That is, when the camera state is the second state, after the exposure of the film (every time after one frame is photographed), from setting of the photographing data and the storage pointer to storage are collectively performed.

Step 360 or step 268
When the storage processing of the storage pointer is completed, the process proceeds to the shooting sequence of the next frame or the rewinding sequence as in the first embodiment (steps 370 to 680).

As described above, according to the present embodiment, the process of storing the shooting data and the storage pointer in the memory 60 is divided after each shooting and after the end of the continuous shooting based on the camera situation and the intention of the user. It is possible to select whether to perform it all at once or collectively after one shooting. Therefore, the photographing data and the storage pointer can be stored in the memory 60 by a storage processing method appropriate for the camera situation and the user's intention.
