In step S58, it is determined whether a strobe light emission request has been issued. Here, if a strobe light emission request has been made, the process proceeds to step S61, and if the request has not been made, the process proceeds to step S59. Then, in step S59, a strobe light emission request is set, and in the following step S60, a strobe light emission amount for catchlight is set.

In step S61, it is determined whether or not the second-stage switch of the release detection switch, that is, the second release detection switch 46, is on. Here, the second release detection switch 4
If the switch 6 is not turned on, the process proceeds to step S62. If the switch 6 is turned on, the process proceeds to step S63.

In step S62, the first-stage switch of the release detection switch, which is the two-stage switch,
That is, it is determined whether the first release detection switch 45 is turned off. Here, if the first release detection switch 45 is not off, the process proceeds to step S61, and if it is off, the process proceeds to step S75.

In step S63, when the infinity mode is not selected, the infinity mode obtained in step S55 is selected based on the focusing feed amount calculation obtained in step S53. Focus sync lens drive control, which is a focus adjustment operation, is performed based on the amount of extension. Next, in step S64, it is determined whether a strobe light emission request has been set. Here, if the strobe light emission request has not been set, the process proceeds to step S67, and if it has been set, the process proceeds to step S65.

In step S65, it is determined whether or not the camera is in the red-eye reduction mode. Here, if the current mode is not the red-eye reduction mode, the process proceeds to step S67. On the other hand, if the mode is the red-eye reduction mode, the flow shifts to step S66 to perform strobe light emission control for red-eye reduction.

In step S67, based on the photometric calculation result obtained in step S56, if a shutter opening / closing request and a strobe light emission request are set, a strobe light is emitted. In particular, when the catchlight mode is selected and the catchlight emission amount is set in step S60, the strobe is emitted based on the catchlight emission amount. This step S6
When a series of exposure control is completed in step 7, the process shifts to step S68 to determine whether or not the continuous shooting mode is being performed.

If it is not in the continuous shooting mode in step S68, the flow shifts to step S73 to set a flag F_WINDREQ indicating a film winding request to "1". On the other hand, if it is in the continuous shooting mode in step S68, the process moves to step S69 to perform the operation of winding up one horse.

Next, in step S70, it is determined whether or not the second release detection switch 46 has been turned off. Here, if the second release detection switch 46 is off, the process proceeds to step S74, and if not, the process proceeds to step S71.

In step S71, it is determined whether a strobe light emission request has been set. Here, if it is determined in step S71 that the strobe light emission request has been set, the process proceeds to step S72.
After charging control of the strobe light emission capacitor is performed as necessary for strobe light emission, the process proceeds to step S67, where exposure control is performed again. On the other hand, step S
If it is determined in step 71 that the strobe light emission request has not been set, the flow shifts to step S67 to perform exposure control again.

In step S74, in step S63
Focusing reset drive control is performed to return the focusing lens whose drive has been controlled to the initial position. Next, after the release request is released in step S75, the process returns to step S8 of the main flowchart.

As described above, the positions where the first mode setting button used in the first specification and the first mode setting button used in the second specification are provided are different.
It is possible to easily confirm which specification is selected simply by checking the position of the first mode setting button without looking at the window display.

In addition, a camera capable of selecting a plurality of specifications can be provided only by replacing the LCD window to which the first mode setting button is fixed. Therefore, it is easy to change not only the time of manufacturing the camera but also the specifications according to the use of the camera.

According to the present embodiment described in detail above, in portrait photography, a flashlight is emitted separately from exposure control to make the subject's pupil shine, The first specification with a red-eye reduction mode that can reduce the so-called red-eye phenomenon by firing the flash prior to shooting during flash shooting, and the infinity that can reliably focus on subjects at infinity A camera with a second mode, in which a mode and a continuous shooting mode in which continuous shooting is performed by holding down the release button are added, simply by replacing the LCD window which can be easily replaced from the outside. It is possible to divide.

In the present embodiment, the display of various modes corresponding to the first specification and the second specification is formed on the LCD window by printing or the like, and when the various modes are selected, By lighting a geometrical display on the LCD at a position corresponding to the display, it is not necessary to provide a large number of display units corresponding to a plurality of specifications on the LCD. Can be achieved.

In the above-described embodiment, each of the derivative mode switches is selected from two modes and no mode selection. However, the third mode may be selected instead of no mode selection. Of course it is good.

Although the first mode setting button has substantially the same shape, for example, the shape of the top of the button may be different between the first specification and the second specification.

In the above-described embodiment, the selection by each derivative mode switch is made of two modes and no mode selection. However, more modes may be selectable, or only one mode may be selected. Needless to say, if an LCD window having no first mode setting button is attached to the camera, a camera of the third specification to which a mode by the first mode setting button is not added at all can be provided. It can be easily made.

If the top of the first mode setting button and the color of the first mode setting button are changed according to the first specification and the second specification, which specification is selected at a glance, it is convenient.

Further, the shapes and configurations of the conductive portion and the land pattern formed by conductive printing formed on the contact portion at the bottom of the first mode setting button are not limited to the above-described embodiment. For example, the land pattern is not limited to the shape shown in FIG. 7B, that is, a pair of land patterns provided with the first and second patterns is provided, and the land pattern is operated by operating buttons. Needless to say, any other pattern can be used as long as it allows conduction.

Further, in the present embodiment, a pair of land patterns is provided at two places, and the operation buttons are selectively arranged at the positions corresponding to the two land patterns. If one with the attached button and one without the corresponding operation button is prepared, the third specification, the fourth specification
The camera having the specifications can be easily manufactured.

According to the above embodiment of the present invention,
The following configuration can be obtained.

(1) A first switch composed of a pair of electrical contacts for selecting a camera mode, and a pair of electrical contacts corresponding to an operating member different from the operating member for operating the first switch A camera comprising: a second switch composed of: and an operation member that can operate the switch only in one of the first switch and the second switch.
