Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention provides an AF mode with two selectable types: AF mode, AF mode, and one-shot mode; Exposure programs with many program diagrams such as feed mode, shutter high-speed program diagram, low-speed shutter program diagram, etc. Select one of several types of shooting operation (operation from shutter open to shutter closed) This invention relates to a camera in which shooting conditions can be set, and which has a series of settings that are respectively set for each of the following situations.

(Background of the Invention) Conventionally, in addition to the first program mode in which the aperture value and exposure time are uniquely determined based on the photometric value obtained by the photometer, the photographer has been able to set the AF mode, feeding mode, program diagram, etc. Various cameras have been proposed that have a second program mode that can be set arbitrarily according to the user's intention. For these cameras, when selecting the second program mode,
The photographer selects and sets one of the modes depending on the shooting situation he or she is shooting. For example, when performing sports photography, the AF mode is servo, the feed mode is continuous photography, and the program diagram is selected from a high-speed shutter program diagram, and the mode settings are made for each.

However, in the conventional example described above, the settings for each mode must be input every time the shooting scene is changed.
It was extremely annoying. For example, when changing from sports photography to landscape photography, you can change the AF mode from servo to one shot, and change the feed mode from continuous to single frame photography.
In addition, the program diagram had to be changed to a low-speed shutter side program that takes depth of field into consideration, and many operating procedures were required.

Also, for beginners, when shooting under certain shooting conditions, they may not know which AF mode, feed mode, or program diagram to set, and may shoot with inappropriate settings.
Occasionally, the result would be a preliminary photo or an out-of-focus photo.

(Objective of the Invention) The object of the present invention is to solve the above-mentioned problems, improve operability, and provide an easy-to-use camera even for people who are not familiar with camera operation.
To provide a camera capable of setting photographing conditions and capable of providing appropriate photographs matching the photographing conditions at that time.

(Features of the Invention) In order to achieve the above object, the present invention provides a photographing situation mode manual means for manually selecting a mode corresponding to the current photographing situation from among various selectable photographing situation modes; a storage means for storing in advance a series of combinations of setting modes suitable for each shooting situation; a detection means for detecting the shooting situation mode input by the shooting situation input means; and a detection means for detecting the shooting situation mode input by the shooting situation input means. A series of setting modes corresponding to each shooting situation mode,
A control means for automatically selecting and setting the AF mode from the storage means is provided, and by simply inputting the mode information of the current shooting situation, the AF mode and the AF mode that are most suitable for the shooting situation at that time can be set. The present invention is characterized in that a series of setting modes such as transmission mode, exposure program, etc. are automatically set.

(Embodiments of the Invention) Hereinafter, the present invention will be described in detail based on illustrated embodiments.

FIG. 1 is an external view of a camera according to an embodiment of the present invention. In the figure, SWI is a shirt release button, SW3 is a changeover switch for switching whether or not to use a strobe, and the accessory shoe ASI of the camera is connected to the strobe. It is placed in a position where it will automatically turn on when you install it. D.I.
ALL is a dial for manually controlling the shooting situation mode. SW4 is a setting button for inputting the shooting situation mode, and without pressing the setting button SW4, the dial D is pressed.
Manual shooting situation mode is possible by rotating the IALI. DISP 1 is a display device that is used both to display the shooting status mode and to display the frame counter. It is composed of a liquid crystal display, and normally displays a frame count, or when the setting button SW4 is pressed. The display switches to display the shooting status.

The shooting situation modes include 1) a mode suitable for shooting at home (hereinafter referred to as family mode), 2) a mode suitable for snapshot photography (hereinafter referred to as snap mode), and 3) a mode suitable for landscape photography (hereinafter referred to as landscape mode). 4) Mode suitable for sports photography (hereinafter referred to as Spora mode) 5) Mode suitable for portrait photography (hereinafter referred to as Portrait mode) 6) Mode suitable for close-up photography (hereinafter referred to as Close-up mode) 7) There are seven modes suitable for party photography (hereinafter referred to as party mode). By rotating dial DIAL 1 while pressing the setting button SW4, the program will be displayed on the display DISPI as shown in Figure 2. The character P”° and a number corresponding to the set shooting situation are displayed.

Therefore, when the shirt release button SWI is pressed, the camera starts the release operation, but if 1" is displayed on the DISP 1 display at this time, ° "2"" is displayed in family mode. If it is displayed, it is in Snap mode, if Pa3° is displayed, it is in Landscape mode, if "4" is displayed, it is in Sports mode, and if "5" is displayed, it is in Landscape mode. If "6" is displayed, the shooting operation will proceed in portrait mode, if "7" is displayed, the shooting operation will proceed in party mode. Therefore, the photographer All you need to do is select the number that matches the shooting situation with the dial DIALL and press the release button.After that, you can set the AF mode to ``Funshot'' or servo, and the feed mode to set continuous shooting or single frame shooting. The settings and the settings of any of the program diagrams described later are automatically performed in the optimal combination according to the shooting situation at the time, and as a result, it is possible to take proper photos without failure in any shooting situation. becomes possible.

In addition, when the setting button SW4 is not pressed, including during release, and when the so-called shooting situation mode is not set, a frame counter is displayed as shown in FIG. 3. In this case, a rectangular frame surrounding the number is displayed at the same time to indicate that the frame counter is displayed. Furthermore, when a shooting situation mode other than the family mode is input, the program "P" is displayed blinking to alert the photographer. This is because shooting in family mode is common and doesn't have much special features, but no matter what you shoot, it won't be a major failure, but on the other hand, shooting in other modes may result in unsuccessful photos depending on the subject. This is to give a warning.

Next, when performing strobe photography, when it is detected that a strobe is attached to the accessory shoe ASI by turning on the changeover switch SW3, the camera operation is switched to strobe mode. When performing strobe photography, a strobe program diagram (hereinafter referred to as a strobe diagram) suitable for each photography situation is selected as described later.

Here, FIG. 4 shows combinations of modes that are considered to be optimal for each shooting situation.

As is clear from FIG. 4, in this embodiment, in the family mode, the AF mode is one shot, the feeding mode is one frame shooting, and the program diagram when the strobe is not used is ■.
The strobe diagram when using a strobe is ■, the snap mode is AF mode is servo, the feeding mode is continuous shooting, the program diagram when not using a strobe is ■, the strobe diagram when using a strobe is ■, landscape mode Here, the AF mode is one-shot, the feeding mode is 1-frame shooting, the program diagram when the strobe is not used is ■, the strobe diagram when the strobe is used is ■, and in the sports mode, the AF mode is servo and the feeding mode is The program diagram when continuous shooting and no strobe is used is ■ The strobe diagram when a strobe is used ■ In portrait mode, the AF mode is one shot, the feeding mode is continuous shooting, and the program diagram is when no strobe is used Is it a strobe diagram when using a strobe? In close mode, AF mode is one shot, feeding mode is one frame shooting,

(Reasons for selecting AF mode) Family mode, landscape mode, portrait mode,
In close-up mode and party mode, you won't be tracking a moving object that moves at high speed, so the AF mode will use a one-shot mode that stops focusing once it's in focus, and on the other hand, in snap mode and sports mode, you won't be able to track a subject that is moving to a certain extent. I will be chasing you, so A.
The F Moto uses a servo that constantly tracks the subject and performs focusing operations.

(Reason for selecting feeding mode) In family mode, landscape mode, close moto, and party mode, each frame is normally shot separately, so one frame is shot. Especially in family mode, even if you accidentally press and hold the shirt release button SWI,
It can be said that the specification settings are easy to use even for beginners, as there is no need to take two frames. On the other hand, in Snap mode, Sports Moto, and Portrait modes, it is desirable to shoot continuously in order to avoid capturing the movement of the subject or subtle changes in facial expressions.

If this is not the case, the process returns to step 2 and the next photographing operation is started in order to perform continuous photographing.

[Step 28] If the feeding mode is single frame shooting, -
Since the next photograph will not be taken unless the hand is released from the shirt release button SWI, the process remains in step 28 until the button SWI is released (turned off). Therefore, the state of the hot button SWI is read from the input port P9, and when it is turned off, the process returns to step 2 to prepare for the next photographing operation.
