DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide digital still camera capable of performing both photography on a silver halide film and photography using a digital imaging device.

[0002]

2. Description of the Related Art In recent years, a silver halide digital still camera has been made capable of electronically using an image pickup device such as a CCD or so-called digital photography while photographing a photosensitive film represented by a silver halide film. Has been proposed. This type of camera has the advantage of obtaining a high-quality captured image by silver halide film photography by appropriately selecting between silver halide film photography and digital photography, and allows the photographed image by digital photography to be immediately confirmed. In addition, since it is possible to realize photographing utilizing each of the advantages of being able to retake images, it is possible to further enhance the convenience of the camera.

[0003]

However, on the other hand, since the silver halide film photography and the digital photography are configured independently of each other, the disadvantages of each photography mode remain. There is. For example, in digital photographing, it is possible to record photographed image data on a recording device and, at the same time, record photographing data such as date and time of photographing and photographing conditions on the same recording device. It is possible to use the photographing data. On the other hand, in silver halide film photography, in order to record photography data such as digital photography on a silver halide film, for example, recording photography data on a silver halide film by an optical method, or like an APS film, Photographing data is recorded by an electric method using a magnetic layer provided on a part of the silver halide film. For this reason, it is necessary to dispose a mechanism for performing these recordings in the camera, which leads to an increase in the number of parts and an increase in the price of the camera. Further, in this technique, since the photographing data is recorded in a limited area of the silver halide film, the recordable photographing data is largely limited, so that the desired photographing data may not be recorded in some cases.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to sufficiently record photographic data desired in silver halide film photography, while eliminating the need for a mechanism for recording and preventing an increase in camera components. An object of the present invention is to provide a silver halide digital dual-use still camera in which the size and cost of the camera are reduced.

The photographing operation of the camera having the above configuration will be described with reference to the flowchart of FIG. The control circuit 121
From the state of the half-press switch 112a, release button 1
When it is detected that 12 is half-pressed (S101), A
The distance measurement circuit 137 measures the distance based on the output from the F sensor 136, and the lens driving circuit 13 based on the distance measurement data.
3 controls the lens driving mechanism 103 to execute a focusing operation (S102). The finder optical system 108
Is a fixed focus configuration, so that it is always in focus and no AF operation is performed. Subsequently, photometry is performed by the photometry circuit 139 based on the output from the photometry sensor 138 (S103), and the aperture value of the aperture mechanism 104 is set based on the photometry data. Then, it is determined whether the release button 112 is fully pressed from the state of the full-press switch 112b (S104). If not, it is determined whether the release button 112 is turned off (S10).
5) Depending on the state, the process proceeds to step S101 or S103. When it is detected that the release button 112 is fully pressed, the setting mode is changed from the state of the mode switch 114 to the “digital single shooting mode” M
1. It is determined which of the “silver-salt film single photographing mode” M2 and the “silver-salt / digital simultaneous photographing mode” M3 (S106), and the process proceeds to each mode process described below.

In the case of the "digital single photographing mode" M1, an exposure operation in the digital camera section is executed (S1).
11). Here, in the digital camera unit, the control circuit 121 operates based on the photometric data and the image sensor driving circuit 13
1 to set the charge accumulation time in the image sensor 110. Then, the subject image formed by the finder optical system 108 is photoelectrically converted by the image sensor 110, and the obtained image signal is converted into digitized image data of a predetermined level by the gain control 122 and the A / D converter 123. A predetermined process is performed in the processing circuit 124. Then, the image data is converted to a D / A converter 125.
, And the photographed subject image is displayed as a monitor image on the liquid crystal monitor 111 by the liquid crystal drive circuit 126. At the same time, the image data obtained is written into the field memory 128, and a digital photographing operation is executed (S111).

Next, shooting data, for example, shooting date and time,
Data such as the charge storage time in the image sensor is acquired (S112), and digital image additional information to which data to be recorded together with the imaging is added is constructed (S1).
13). Then, the constructed digital image additional information is recorded in the flash memory 130 together with the image data (S114). In recording on the flash memory 130, one file 200 is constructed for one image data as shown in FIG. 5 showing the file structure of the recording information in the flash memory 130. Each file includes a file header area 201 for recording file format identification information and the like, an image data area 202 for recording the image data, a digital image additional information area 203, and a silver halide camera unit shooting data area 204. As described above, when the image data is recorded in the flash memory 130, the required header information is recorded in the file header area 201, and the compressed image data is recorded in the image data area 202. The digital image additional information is recorded in the additional information area 203. This allows
The image data and the photographing data are recorded in the flash memory 130. The image data is compressed data or RGB format image data.

On the other hand, the "silver film independent shooting mode" M
In the case of 2, the lens driving mechanism 103 is set to a position on the predetermined optical axis by the focusing operation performed in step S102, and the diaphragm mechanism 104 is set to the predetermined aperture value by the photometry operation performed in step S103. Is set to Further, the shutter drive circuit 135 drives the shutter mechanism based on the shutter speed obtained from the photometric operation, and exposes the subject image formed by the photographing lens 102 to the silver halide film 107 (S121). Then, following this photographing, the control circuit 121 outputs data obtained inside the camera at the time of the photographing or data input by the photographer in advance, such as date and time, film management number, frame number, aperture value, shutter Photographing data is acquired based on various data such as speed, lens focal length, photometry method, exposure method, and exposure correction amount (S122), and the constructed photographing data is photographed in the silver halide camera section of the file 200 of the flash memory 130. The data is recorded in the data area 204 (S123). In this case, the header information of 201 is recorded in the file header area, but is not recorded in the digital image addition area 203 and the image data area 202. Therefore, the file capacity is reduced.

Also, a “silver salt digital simultaneous shooting mode” M
In the case of No. 3, exposure in silver halide film photography is performed in the same manner as described above (S131), and then digital photography is performed (S131).
132), and further, acquisition of silver halide camera section photographing data (S1).
33) and the construction of the digital image additional information (S134), these data are stored in the digital image additional information area 20 of the corresponding file 200 in the flash memory 130.
3 and the image data 204 of the silver halide camera unit (S135).

As described above, while the image data and the photographing data in the digital photographing are recorded in the flash memory 130, the photographing data in the silver halide film photographing can be recorded in the same flash memory 130. Therefore, when it is desired to refer to the photographing data of the silver halide film photographing after photographing with the silver halide film, the file of the flash memory 130 corresponding to the photographed image is opened and the recorded photographing data of the silver halide camera unit is displayed on the liquid crystal display. This can be displayed on the section 118. In addition, when the digitally captured image data is displayed on the liquid crystal monitor 111, the digital image additional information can be displayed on the liquid crystal display unit 118 at the same time. In the shooting in the “silver salt digital simultaneous shooting mode”, the digitally shot image data is displayed on the liquid crystal monitor 111 and the digital image additional information and the silver halide camera section shooting data are simultaneously displayed on the liquid crystal display unit 11.
8 will be displayed. Files to be opened on the liquid crystal monitor 111 and the liquid crystal display unit 118 can be sequentially switched by an up switch 116 and a down switch 117.

In the above-described embodiment, an example is shown in which the present invention is applied to a lens shutter camera. However, it is needless to say that the present invention can be similarly applied to a single-lens reflex camera camera. Further, although a flash memory is shown as an example of a recording medium for recording image data and photographing data, the present invention can be applied to a camera provided with a recording medium of another system as long as the recording apparatus can electrically record. The same can be applied.

Further, in the above embodiment, the focus operation and the photometry operation are performed when the release button is half-pressed, and the photographing mode is determined when the release button is fully pressed. In the case of the camera of the system, since the focusing operation is not performed at the time of digital photographing as in the above embodiment, for example, when the release button is half-pressed, the photographing mode is determined first, and the silver halide The focusing operation may be performed only when film shooting is included.

[0019]

As described above, the present invention has a means for storing photographing data of silver halide film photographing in a recording device for recording image data of digital photographing. Can record a large amount of photographing data in the camera, eliminating the need for a mechanism for recording silver halide film photographing data, making it possible to reduce the size and cost of the camera, and to achieve many photographing operations on already photographed silver halide film. Data management can be realized. In particular, by recording the photographing data for the silver halide film photographed image and the additional information of the digital photographed image in the same file in the recording device for the image photographed at the same time, the silver halide film photographed image, the digital photographed image and It is possible to easily compare the respective photographing data with the additional information, and it is also possible to more appropriately perform image management.
