Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a camera that can select a plurality of photographing modes.

[Conventional technology]

A camera equipped with programmable AE determines the shutter speed and aperture value according to the brightness of the subject, so it is convenient to take photographs.

However, since this programmable AE uniquely photographs the subject, there is a problem in that the photograph cannot be taken as intended by the photographer. For this reason, recent cameras are equipped with a manual shooting mode device such as a dial or button on the camera body so that the programmable AE can be changed to the shooting mode intended by the photographer, so that the desired photograph can be taken. On such cameras, to make it easy to know which shooting mode has been changed, a display mark is written on the dial, a display mark is placed next to the button, and a comment is also displayed on the LCD display. There is.

[Problem to be solved by the invention]

By the way, the camera body mentioned above incorporates a finder, a strobe, etc., and the size of the mode input device and liquid crystal panel is limited due to space issues, making it impossible to make the display marks, comments, etc. larger. For this reason,
These displays do not provide sufficient information to the photographer to suggest a photographic scene corresponding to the photographing mode, so there is a problem in that an inexperienced photographer cannot select an appropriate photographing mode.

Additionally, ``There are cameras like the Canon EO3J that allow you to set the shooting mode that corresponds to the shooting scene while looking at the photo, but this camera requires an art code book and a barcode reader in addition to the camera itself. There are issues of cost and portability.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an inexpensive camera in which the photographing mode is displayed with an illustration so that the photographing mode can be easily and appropriately selected.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an illustration ring that is provided on a lens barrel and has a plurality of illustrations arranged around its outer periphery, a selection means for selecting one illustration from the plurality of illustrations, and a selection means for selecting one illustration from among the plurality of illustrations. The camera body is provided with mode setting means for setting a photographing mode corresponding to the illustration selected by the means.

[Effect]

According to the above configuration, when the selection means selects one illustration from among the plurality of illustrations, the mode setting means sets the camera to a shooting mode corresponding to the selected illustration.

Hereinafter, the present invention will be explained according to the illustrated embodiments.

〔Example〕

FIG. 3 shows an embodiment of the camera of the present invention,
On the front side of this camera body 2 is a lens barrel 4 that holds a photographic lens 3. 5. A photometering window with a photometer behind it that measures the subject brightness. A finder window 6° and a strobe 7 are provided. The lens barrel 4 has a mode ring 8 for setting the shooting mode.
is rotatably provided. Further, a display window 9 is formed at the top of the lens barrel 4 to display an illustration corresponding to the shooting mode. Note that since the display window 9 is provided in an empty space of the lens barrel 4, it can be made large enough to facilitate observation. Further, a grip 11 incorporating a release button 10 is provided at the end of the camera body 2, and a liquid crystal display section 12 for displaying shooting information such as the number of remaining films is provided on the top surface.

FIG. 1 shows the main parts of the camera of the present invention, and a lens barrel frame 16 is screwed to the main body base plate 15 of the camera body 2. As shown in FIG. A click pin 1 is provided on the outer peripheral surface of the lens barrel frame 16.
7 is provided, and this click pin 17 engages with the mode ring 8 to click-stop the rotating mode ring 8 at a predetermined position. In addition, this lens barrel frame 16
A locking pin 18 is formed in the locking pin 18.
positions the code plate 19 fixed to the base of the lens barrel frame 16.

Five concentric conductor patterns 21 to 25 are printed on the surface of the code plate 19 from the outside. The outer conductor pattern 21 is continuous as shown in black in FIG. 2(A), but the four inner conductor patterns 22 to 25 are separated at some places. The conductor patterns 22 to 25 are used as 4-bit gray codes, and the lowest to lowest
Output the highest binary data. These conductor patterns 21-25 are connected to conductor patterns 21a-25a printed inside the code board 19, respectively, as shown in FIG. 2(B). These conductor patterns 21a to 25
a are respectively connected to the CPU 27 via lead wires. A signal generator 28 is connected to the CPU 27, and the signal generator 28 outputs a half-press signal and a release signal at the timing when the release button 10 is pressed halfway and fully pressed, respectively. Further, a ROM 29 in which an exposure control program is written is connected to the CPU 27.

The CPU 27 controls by applying a voltage to the conductor pattern 21 and detecting 4-bit position data from the conductor patterns 22 to 25 by inputting a half-press signal. Thereafter, the control of the CPU 27 reads an exposure control program corresponding to the position data from the ROM 29, and determines the optimum shutter speed and aperture value by referring to the subject brightness measured by the photometer, film sensitivity information, etc. Further, when a release signal is input, the CPU 27 operates the shutter and the aperture according to the selected shooting mode to take a picture.

Further, an illustration ring 30 that slides into contact with the code plate 19 is rotatably fitted into the lens barrel frame 16.

On the outer circumferential surface of this illustration ring 30, fifteen illustrations 31a to 310 and letters of standard mode are drawn clockwise. Note that since the illustration ring 30 is provided in an empty space of the lens barrel 4, each illustration 31a
The outer circumferential surface can be widened to provide a large space for ~31o. Therefore, the illustrations 31a to 31o can be made to be associated with photographing modes. A sliding brush 32 that contacts the conductive patterns 21 to 25 is formed on this illustration ring 30. Furthermore, a notch 33 is formed in the illustration ring 30, and a protrusion 34 formed in the mode ring 8 is fitted into this notch 33. Therefore, the illustration ring 30 is rotated by the mode ring 8. Furthermore, sixteen notches 35 into which the click pins 17 fit are formed on the inner circumferential surface of the mode ring 8. As a result, the mode ring 8 is click-stopped at 16 places when rotating, so the display core 9 has an illustration 3.
One illustration from 1a to 310 or a character in standard mode is surely displayed.

FIG. 4 shows a part of the illustration drawn on the illustration ring. Illustration 31a shows the portrait mode, and depicts a person in a blurred background. Further, the illustration 31b shows a sports mode, and depicts an athlete. Furthermore, illustration 31c shows the macro mode, and depicts a flower with a close-a knob. Illustration 31 below
d to 31o have pictures corresponding to other modes.

The operation of the camera configured in this way will be explained.

In portrait mode, for example, when photographing a person with a blurred background, first rotate the mode ring 8. Due to this rotation, the illustration ring 30 is rotated via the protrusion 34, and the illustration 31a is displayed on the display window 9. In addition, the mode ring 8 can be clicked by the click bin 17.
Since the knob is rotated, parts of the two illustrations will not be displayed on the display window 9 straddling the two illustrations. After this, when the release button 10 is pressed halfway, the CPU 27
A voltage is applied to the sliding brush 32 via. At this time,
Since the conductive pattern 25 is in contact with this sliding brush 32, the code plate 19 sends the 4-bit "10" to the CPU 27.
00'' position data is output. In this state, when the release button 10 is fully pressed, the CPU 27
The camera reads an exposure control program suitable for portrait mode from , and shoots in aperture priority mode with a large aperture.

Also, when shooting in sports mode or macro mode, rotate the mode ring 8 counterclockwise and display window 9.
