Abstract

PURPOSE:To provide a camera by which a user takes great fun in various printed pictures having different aspect ratios. CONSTITUTION:An aperture 18 having the aspect ratio 1.5-1.9 as a standard photographic image plane is adopted, and the aspect ratio of the aperture 18 is changed by making two image plane regulating members 19 and 20 get in from two opposed long sides of the aperture 18 so that photographing may be performed by using at least three image planes having different aspect ratios. Since the length of the long side is not changed even though the aspect ratio is changed, the image circle of a photographing lens is effectively used. By adopting the image plane having the large aspect ratio as the standard image plane, the change of enlarging magnification is decreased, and it is advantageous to printing operation.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention makes it possible to easily obtain not only standard-sized print photographs obtained by photographing and printing within the standard exposure range defined by the aperture, but also cropped print photographs with a large aspect ratio. This is about a camera that has been used.

0002

[Prior Art] Some of the recent 35mm full-size compact cameras, such as the "Cardia Travel Mini" (product name) sold by the applicant, are capable of receiving panoramic printing services. There is something. In such cameras, the aperture size that regulates the exposure range for the film is 24 mm x 36 mm (aspect ratio 1.5), which is equivalent to a 35 mm full frame. Normally, images are taken through this aperture, but panoramic When intending to print, insert mask plates from above and below the aperture, and make a 13mm x 36m
It is now possible to take pictures in a horizontally long exposure range of "m" (aspect ratio approximately 2.8). When printing from a film taken on such a horizontally long screen, the printing magnification is approximately doubled to provide a horizontally long panoramic print photograph with an aspect ratio of approximately 2.8.

[0003] With the spread of the above-mentioned panoramic printing service, various demands regarding the size of printed photographs have been aroused among general users. In particular, when the aspect ratio of a printed photograph is increased, it is possible to give the photographic image greater breadth and depth, allowing users to enjoy photographic images that could not be obtained with conventional printed photographs with a uniform aspect ratio. You will be able to do this.

0004

[Problems to be Solved by the Invention] Considering this background, conventional cameras have an aspect ratio of "1.5".
A normal printed photo or one with an aspect ratio of 2.
．． I was only able to obtain one of the 8 panoramic print photos. For this reason, depending on the photographed scene, a normal print photograph has a small aspect ratio, and a panoramic print photograph has an aspect ratio that is too large. Of course, it is theoretically possible to obtain printed photos with a somewhat satisfactory aspect ratio if you make a special order when requesting prints.
With such a method, it is difficult to provide printed photographs with various aspect ratios to the general public, and the cost is also high.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a camera that allows the user to widely enjoy various printed photographs having different aspect ratios.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the camera of the present invention has an aperture that defines the standard exposure range of photographic film with an aspect ratio of 1.5 to 1.9, and a camera that defines the standard exposure range of the photographic film. The present invention is provided with trimming setting means for narrowing the standard exposure range by entering from two opposing long sides and setting at least two trimming exposure ranges having a larger aspect ratio than the standard exposure range.

Another camera of the present invention has an aperture that defines the standard exposure range of photographic film with an aspect ratio of 1.5 to 1.9, and an aperture that specifies the standard exposure range of photographic film with an aspect ratio of 1.5 to 1.9, and an aperture that specifies the standard exposure range of a photographic film with an aspect ratio of 1.5 to 1.9. a print mode setting means for selecting one of the print mode or at least two types of trimming print modes for printing a part of the screen photographed in a standard exposure range with different aspect ratios; and data recording means for recording print mode data on the film.

[0008]

[Embodiment] In FIG. 2 showing the external appearance of a camera which is an embodiment of the present invention, a photographing lens 3 is provided at the center of the front surface of the camera body 2, a finder 4 is provided at the upper center, and a viewfinder 4 is provided at the upper left of the camera body 2. A strobe light emitting unit 6 is provided in the upper right part of the distance measuring windows 5a and 5b. In addition to the shutter button 7, the upper part of the camera body 2 is provided with a screen size switching knob 8 that can be slid freely along a slit 9 to change the screen size to four levels: L, H, C, and P.

[0009] L has a standard screen with a screen size of 24 mm x 36 mm and an aspect ratio of 1.5, and H has a screen size of 20 mm.
．． A high-definition screen with a size of 2mm x 36mm and an aspect ratio of 1.78, C has a screen size of 15.7mm x 36mm
P indicates a cinemascope screen with an aspect ratio of 2.30, and P indicates a panoramic screen with a screen size of 12.7 mm x 36 mm and an aspect ratio of 2.84. In addition,
A high-definition screen is a high-definition television screen, and images taken on this size screen are advantageous because they do not need to be trimmed when converted to electronic images such as electronic still images.

As shown in FIG. 1, the screen size switching knob 8 is connected to the head of a lever 12 fixed to a fan-shaped gear 11. By sliding the screen size switching knob 8, the gear 11 is rotated. be done. A click stop mechanism 13 is provided at the end of the gear 11 to regulate the stopping angle of the gear 11, and stops the gear 11 at four positions corresponding to the L, H, C, and P positions.

Gears 14 and 15 mesh with gear 11, and gear 16 meshes with gear 15. A screen regulating member 19, which integrally forms the upper long side of the aperture 18 with the shaft 14a, is fixed to the gear 14. Similarly, the gear 16 has an aperture 1 integrated with this shaft 16a.
A screen regulating member 20 forming the lower long side of the screen 8 is fixed. The gears 14, 15, and 16 all have the same pitch, and when the gear 11 rotates, the screen regulating members 19, 20 are rotated by the same angle in opposite directions. Note that the reference numeral 21 indicates a film set in the aperture 18. Further, reference numeral 22 is a shutter mechanism provided behind the photographing lens 3.

Although not shown, a switch is provided below the screen size switching knob 8 to change the field of view of the finder 4 in conjunction with the stop position of the screen size switching knob 8. The finder 4 is a Keplerian type real image finder, as shown in FIG.
Porro prism 2 provided between 3 and the eyepiece 24
A liquid crystal display board 26 indicating a field of view frame is provided on the incident surface side of the display device 5 . As shown in FIG. 4, a pair of line-shaped liquid crystal display sections 27, 28, and 29 are provided on the upper and lower portions of the liquid crystal display panel 26, respectively.

[0013] In order to facilitate selection of the aspect ratio of the photographic screen, each of these display parts has a slight density to the extent that the photographer can distinguish it from other fields of view. When the viewfinder field of view is selected by operating the screen size switching knob 8, the density of the selected viewfinder field becomes slightly higher than the density of the other fields of view, and it is possible to try changing the photographing screen. Then, when the shutter button 7 is pressed halfway, the density of the selected finder field of view becomes even higher, and the field of view can be clearly confirmed.

That is, when the screen size switching knob 8 is set to H and the shutter button 7 is pressed halfway, the liquid crystal display section 27
is driven, the vertical width of the finder visual field 30 corresponding to the standard screen shown in FIG. 5 is changed, and the finder visual field 31 corresponding to the high-definition screen shown in FIG. 6 is displayed. Further, when the screen size switching knob 8 is set to C and the shutter button 7 is pressed halfway, the liquid crystal display sections 27 and 28 are simultaneously driven to display a viewfinder field of view 32 corresponding to a cinemascope screen as shown in FIG. . Similarly,
When the screen size switching knob 8 is set to P and the shutter button 7 is pressed halfway, all of the liquid crystal display sections 27, 28, and 29 are driven at the same time, and a finder field of view 33 corresponding to a panoramic screen as shown in FIG. 8 is displayed. Ru.

The operation of the camera configured as above will be explained. To select the screen size, use the screen size switching knob 8.
This is done by moving back and forth along the slit 9. For example, to switch from a standard screen to a cinemascope screen, the screen size switching knob 8 is moved from L to C. As a result, the gear 11 is rotated counterclockwise via the lever 12, the gear 14 is rotated clockwise, and the gear 16 is rotated counterclockwise.
is rotated counterclockwise via gear 15 and click-stopped at a position corresponding to the cinemascope screen.

As a result, the screen regulating members 19 and 20 narrow the width of the short side of the aperture 18 to change the aspect ratio of the photographic screen, and the screen size is changed from 35 mm full size to a cinemascope screen. At the same time, the liquid crystal display sections 27 and 28 of the liquid crystal display board 26 are switched to the liquid crystal display section 29.
It is driven to have a slightly higher concentration. When the shutter button 7 is pressed halfway, the viewfinder visual field 32 corresponding to the cinemascope screen shown in FIG. 7 is clearly displayed. The photographer decides on a composition according to the viewfinder field of view 32, and when the shutter button 7 is pressed, the shutter mechanism 22 is driven and a cinema scope size screen is exposed on the film 21 set in the aperture 18.

When changing to another screen, any one of the four types of screens can be selected by simply operating the screen size switching knob 8 in the same manner. Note that it is advantageous for printing work if the screens imprinted on a single film have the same aspect ratio, but for example, if a sensor is installed on the printer side to identify the aspect ratio of each screen, By changing the stretching magnification to a corresponding one and printing separately, it is possible to arbitrarily switch the aspect ratio of the screen even during shooting, and to imprint multiple screens with different aspect ratios on a single film.

In the embodiments described above, a 35 mm full-size screen with an aspect ratio of 1.5 is used as the standard screen, but a high-definition screen with an aspect ratio of 1.78, for example, may be used as the standard screen. In this case, there is an advantage that the viewfinder magnification can be increased, and that there is no need to greatly change the stretch magnification when printing a screen with a different aspect ratio. Furthermore, it goes without saying that the present invention is not limited to the numerical value of the aspect ratio or the number of screens. In this embodiment, a Keplerian type real image finder is used as the finder 4, but a daylight finder or other real image zoom finder may be used.

Further, in this embodiment, the screen size is changed by mechanical knob operation, but for example, a stepping motor may be used to sequentially change the screen size each time the operation button is pressed once. It is also possible to return to the standard screen upon receiving a photographing end signal every time the photographing is completed. In addition, methods to return to the standard screen include a timer method that returns the screen after a predetermined amount of time has passed after setting the screen to a screen with a different aspect ratio, and a main switch interlocking method that returns the screen to the standard screen when the camera's power switch is turned off. But that's fine.

Next, another camera of the present invention will be described with reference to FIG. 9, which shows a film 35 taken with this camera. The aperture of the camera is high-definition size, and between each shooting screen 36 of the film 35 used for this, H indicating high-definition size, C indicating cinema scope size,
Points P indicating the panoramic size and points indicating their trimming positions are each pre-exposed. Further, at the top and bottom of each photographic screen 36, L indicating 35 mm full size and a point indicating its trimming position are pre-exposed. The pre-exposure positions of these symbols L, H, C, P and the points indicating the trimming positions are accurately defined based on the position of the perforation 37.

At the bottom of the photographing screen 36, there are two information recording areas 38 and 39, upper and lower. Film feeding speed information is recorded. At the same time, trimming information of the photographic screen 36 and the like are recorded in the information recording area 39 at the lower stage. When such a film 35 is applied to the printer, the stretching magnification is automatically set based on the trimming information recorded in the information recording area 39, and a printed photograph having the aspect ratio intended by the photographer is printed.

[0022]

As explained above, the camera of the present invention narrows the standard exposure range defined by the aperture with an aspect ratio of 1.5 to 1.9, and narrows the standard exposure range defined by the aperture with an aspect ratio of 1.5 to 1.9. Since the cropping exposure range can be set, you can enjoy a wide variety of printed photos with different aspect ratios. Furthermore, even if the aspect ratio is changed, the length of the long side remains the same, allowing effective use of the image circle of the photographic lens. Furthermore, if a screen with a large aspect ratio is used as the standard screen, changes in the stretching magnification can be reduced, which is advantageous in printing operations. Also,
Another camera of the present invention has a standard print mode in which the entire area of the screen photographed in the standard exposure range is printed, or at least two types of cropping in which parts of the screen photographed in the standard exposure range are printed at different aspect ratios. Since one of the print modes is selected and the selected print mode data is recorded on the film, it becomes possible to widely enjoy various printed photographs with different aspect ratios with a simple mechanism.
