Field of the Invention The present invention relates to a camera, and more particularly to a method for adjusting a silver halide camera having the function of an electronic image pickup device having an electronic image pickup device for converting a subject image into an electric signal.

[0002]

2. Description of the Related Art In recent years, among so-called silver halide cameras using a silver halide film, many cameras having an electronic imaging function have been proposed. This kind of camera includes an image capturing unit that converts a subject image into an electronic image signal, an electronic image capturing apparatus that includes an electronic image signal captured by the image capturing unit on a recording medium, and includes an image display unit. A silver halide imaging device for exposing a subject image to a silver halide film; and a silver halide imaging and electronic device configured to execute an imaging operation by the electronic imaging device in conjunction with an exposure operation on the silver halide film. It is a camera that can also be used for shooting.

[0003] In a conventional camera having such a configuration, adjustment relating to a silver halide camera and adjustment relating to an electronic camera are performed.
One adjustment is required. However, since the camera has two functions, an additional adjustment space is required in terms of the camera space (internal space).

An extension is provided on the front of the camera, and the extension is overlapped and connected on the front of the camera. Further, an adjustment land is provided on the extension to allow adjustment on the front of the camera.

However, in this prior art, the adjustment pads of the camera are arranged in a concentrated manner by overlapping the respective flexible substrates, but when the adjustment pads are arranged in front of the camera, Has the following problems. First, it is necessary to remove at least all or a plurality of exterior members such as the front of the camera, and there is a difference in the result when the adjustment is performed without the exterior members.

Secondly, in the case of a camera that uses both silver halide photography and electronic photography, an adjustment pad on the camera side is required for electronic photography, but there is actually no space for overlapping a flexible substrate. Third, the adjustment pad on the front of the camera is difficult to attach during adjustment. Therefore, there is a need for a device that allows for easier adjustment in the use and configuration of the camera.

SUMMARY OF THE INVENTION An object of the present invention is to provide a camera which can be easily adjusted in adjusting the photographing of both cameras for both silver halide photography and electronic photography.

[0008]

Means for Solving the Problems In order to solve the above problems and achieve the object, the present invention takes the following measures. That is, according to the first aspect, the camera of the present invention is a camera that combines an adjustable silver halide imaging device that records on a silver halide film and an adjustable electronic imaging device that can capture an electronic image with an electronic imaging device. Electronic components for driving and controlling the silver halide photographing device are mounted, and a first substrate disposed on the front of the camera body and electronic components for driving and controlling the electronic imaging device are mounted. A second substrate having an adjustment check land and disposed on a lower surface of the camera body;

A camera configured and implemented to adjust the silver halide imaging device via a third substrate is proposed.

Further, when a part of the exterior member of the camera is removed, one of the first substrate and the second substrate is exposed so as to be exposed. The present invention proposes a camera characterized in that electrical adjustment of the other substrate from the substrate that has been made possible is made possible.

Also, adjustment pattern lands (103, 104) as adjustment check terminals to be described later are provided at the ends of the DM flexible substrate (81), so that adjustment work is possible.

Next, operation control in the camera according to the present embodiment will be described. The flowchart illustrated in FIG.
It shows a main sequence of a program related to the control procedure of the camera. When a battery as a power supply is loaded into the camera, the main CPU 58 starts operating, and a routine "main sequence" of the control program is started in the main storage area. First, in step S1, whether the power switch of the camera is turned on is checked. It is determined whether or not it is (S1). If the switch is on, the processing from step S4 described below is executed. If the switch is off, the following processing steps are executed from step S2.

In step S2, the LCD panel 74 is turned off, and the image processing LSI 57 is instructed to turn off the display of the LCD monitor 70 (S2). Thereafter, standby processing 1 for a predetermined period is performed (S3). This standby process 1 is for setting conditions for restarting the operation of the main CPU 58 after the stop before stopping the operation of the main CPU 58. In the standby process 1, the operation is set to start at the timing when the power switch is turned on. And the main CPU5
8 is suspended. When the standby state is released, the processing is executed from the head S1 of the main sequence. From step S4, the photographing lenses 30, 32 are extended from the retracted position to the wide position (S4).

In step S5, the LCD panel 74 is turned on (S5). Further, the main capacitor included in the flash circuit 56 is charged (S6). Here, the counting of the timer 1 built in the main CPU 58 is started (S7). The timer 1 is a counter that counts up at a predetermined time interval. The counter value is set to a predetermined initial value, and counting is started.

In the following step S8, it is determined whether or not the first release switch is turned on by pressing the release switch (S8). If it is on, the processing steps from the following step S9 are executed, and if it is off, the process moves to step S16 described later.

From step S9, first, the image processing LSI
57 is turned on (S9), and the subject luminance value is taken in from the photometric sensor (SPD) 65 (S10). Then, a distance between two images is obtained based on a signal input from the autofocus module 41, and driving amount data of a photographing lens for driving to a focusing position is calculated. The motor 39 is driven according to the drive amount, and the focal position of each of the photographing lenses 30 and 32 is changed (S11).

Thereafter, based on the subject luminance value obtained in step S10, a program diagram or the like corresponding to the photographing mode, and the film sensitivity detected by a film sensitivity detection circuit (not shown), an appropriate exposure is performed by a known technique. Is calculated (S12).

In step S13, a subroutine "photographing sequence" is called, and an image is taken by the CMOS imager 48 and the silver halide film 33 is exposed (S13). Then, the process returns to step S5, and the process is repeated in the same manner.

In step S16, it is determined whether or not the operation button is turned on (S16). If the operation button is turned on, each process corresponding to the button pressed in step S17 is performed (S17). Thereafter, the process proceeds to step S18. If it is off, the determination process from the next step S18 is executed.

In step S18, the on / off state of the power switch of the camera is determined (S18). If the power switch is off, the process returns to step S2 to perform the processing. If it is on, further determination processing is performed in step S19. That is, since the timer 1 overflows when a predetermined time elapses after the counting of the timer 1 is started, it is determined here whether the timer 1 overflows (S19). If the timer 1 overflows, the processing from step S20 onward is performed. If the overflow has not yet occurred, the process returns to step S8, and the same processing is repeatedly executed.

From step S20, the LCD panel 74
Is turned off, and the image processing LSI 57 is instructed to turn off the LCD monitor 70 (S20). Then, standby processing 2 is performed (S21). In addition,
This standby processing 2 is the same as the main C
Before stopping the operation of the PU 58, the main C
This is a process for setting conditions for the PU 58 to start operating again. In the standby process 2, the operation is set to be started by a change in a switch linked to the operation button. Then, the operation of the main CPU 58 is stopped. When the standby is released, the same processing is performed from the above-described step S5.

The detailed components of the camera body according to this embodiment will be described. FIG. 5 is an exploded view of the configuration of the camera body and the camera body.

6, the lower cover 24 covering the second substrate is simply removed, and for example, the adjustment terminals (1) on the second substrate are removed.
03), the portion relating to the silver halide photographing function can be adjusted from here via the third substrate. Similarly, if the adjustment terminal (104) is used, a portion related to the electronic imaging function can be adjusted via the third substrate.

That is, since the DM flexible substrate 81 is attached so that the substrate surface 100A is exposed when the lower cover 24 is removed, the DM flexible substrate 81 can be easily removed.
In this state where the connector 80a of No. 0 is visible, the check pins of the adjusting device and the inspection device are
4 to check the signals of each part of the camera independently.

Thus, the inspection and adjustment operation of the internal substrate can be easily performed by removing only the lower cover 24 of the camera, and maintenance can be easily performed.

For example, the various substrates mounted inside the camera may be a hard substrate and a flexible substrate, each of which may be used in an appropriate material and in an appropriate position, and is not limited to the exemplified application examples. Also, the front and back of the substrate are not limited. In addition, the check terminal of the present embodiment is separated for electronic imaging and silver halide shooting, but these may be used in an appropriate combination, or may be used as a USB terminal or a JTAG terminal of other terminals. .

The exterior member to be removed at the time of adjustment is not limited to the lower cover, but may be another exterior member, and can be changed as desired with the change of the arrangement of the substrate. Furthermore, the substrate exposed when the exterior member is removed is not limited to a digital substrate (that is, a substrate on which electronic components for driving and controlling the electronic imaging device are mounted), but an analog substrate (that is, a substrate that drives the silver halide photographing function unit). Of course, a board on which electronic components to be controlled are mounted may be used.

In this embodiment, the data from the check terminal passes through the image processing IC.
You may make it output via a RELAY flexible board. According to these modified embodiments, an effect equal to or greater than that of the exemplary embodiment can be expected. In addition, various modifications can be made without departing from the spirit of the present invention.
