Abstract

PURPOSE:To easily confirm the trimming range at the time of printing by recording the trimming range with characters or symbols, which can be understood visually, nearby a corresponding photographic picture plane on a film. CONSTITUTION:When a print of full size, trimming size(PM), or panorama size (PAN) is specified with switches SW2 - SW4, a shutter 16 is driven to perform exposure and then a microcomputer 17 decides the trimming range from the switches SW2 - SW4. When the SW3 is ON, an imprinting device 13 is driven through an imprinting circuit 12 to imprint characters 'PM' at an imprinting position 14 in the exposed frame. When SW4 is ON, on the other hand, characters 'PAN' are imprinted at the position 14. Then a photographic date, photographic conditions, trimming information, etc., are recorded on the magnetic track 11 on the film 2. Consequently, the intention of composition at the time of photography can easily be confirmed.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a camera capable of recording trimming information specifying a trimming range at the time of printing for a photographic screen shot in full size.

B. Prior Art A camera is known that can record trimming information that specifies a trimming range when printing on a photographed screen shot in full size. That is, by printing only the specified trimming range on both sides of a full-size photograph, a photograph similar to that obtained when zooming up or panorama photographing is obtained. The trimming information of this type of camera is recorded on a magnetic recording medium coated on the film, an IC memory, etc., or it is imprinted on the film as optically encoded information, and when printing, it is recorded on a magnetic recording medium coated on the film, an IC memory, etc. is played back by a playback device. Then, only the specified cropped area from the full-size image will be printed.

C9 Problems to be Solved by the Invention However, in conventional cameras that can record trimming information, the trimming information is recorded magnetically or electrically on a magnetic recording medium or IC memory, so it is difficult to record the negative film after development. There is a problem in that it is impossible to decipher with the naked eye what kind of cropping range was intended for printing the photographed screen just by looking at it, and it is confusing when requesting a print.

Further, even with a method of optically imprinting trimming information, the information is encoded and cannot be deciphered, resulting in a similar problem.

The purpose of the present invention is to record photographic information including trimming information for each frame in a magnetic, electrical, or optical recording format, and to record the trimming range near each photographic screen so that the meaning can be visually understood. Our aim is to provide cameras that are of the highest quality.

00 Means for Solving the Problems The present invention will be explained with reference to FIG. 1, which is a diagram corresponding to the claims.The present invention sets a trimming range at the time of printing with respect to the shooting screen of a film shot in full size. Setting means SW3. SW4, and setting means SW3. SW4
The present invention is applied to a camera capable of recording trimming information, which is equipped with a first recording means 9.10 for recording information on the trimming range set by the above on a recording medium in a recording format that cannot be visually read.

Then, the setting means SW3. is placed near the corresponding photographing screen on the film. The above object is achieved by providing second recording means 12, 13 for recording the trimming range set by SW4 in visually understandable characters or symbols.

81 action The second recording means 12.13 sets the setting means SW3. The trimming range set by SW4 is recorded with visually understandable characters or symbols.

Therefore, just by looking at the developed negative film, it is possible to easily identify the intended cropping range of each photographed screen.

In addition, in the above-mentioned sections and Section E that describe the present invention in detail, the same reference numerals as the elements of the embodiments corresponding to the reference numerals of each means are used to make the present invention easier to understand. It is not limited to the examples.

, F. Embodiment FIG. 2 is a block diagram showing the overall configuration of an embodiment of the present invention.

In the figure, 1 is a film cartridge, 2 is a photographic film, 3 is a winding Lisbourg, 1M is a film winding remoter, and a gear 4. gear 5
．． The take-up spool 3 is driven via a gear 6 and a spool gear 7 fixed to the take-up spool 3. 8 is a motor drive circuit that drives the winding remoter M.

Furthermore, 9 is a magnetic recording circuit that records trimming information on the magnetic track 11 coated with the magnetic recording medium on the film 2 via the magnetic head 10; An imprinting device 15 imprints characters or symbols indicating a trimming range at imprinting positions 14 near each photographic screen; 15 is a shutter drive circuit that drives a shutter 16;

Also, SWI is a switch that is turned on when the shutter release is released, SW2 is a switch that specifies normal full-size printing, SW3 is a switch that specifies printing of a cropped range to obtain a zoomed-in photo, and SW4 is a switch that obtains a panoramic photo. This is a switch that specifies printing of a panorama range.

Reference numeral 17 denotes a control circuit comprised of a microcomputer and its peripheral components, which executes a control program to be described later to control recording of trimming information.

Here, the trimming range set by the apparatus of this embodiment will be explained.

Fig. 3(a) shows the trimming size 21 that is set to obtain a photo with the same angle as when shooting a zoom-up, and Fig. 3(b) shows the trimming size 21 that is set to obtain a photo with the same angle as when shooting a panorama. The panoramic size 22 is shown. rPMJ above the photographing screen 23 in FIG. 3(a) is a character indicating that the imprinting circuit 12 and imprinting device 13 have specified a print of trimming size 21 at the time of photographing, and as shown in FIG. 3(b) rPANJ above the photographing screen 24 is a character indicating that panoramic size 22 printing has been specified. These characters can be visually understood just by looking at the negative film, as described above. Further, a magnetic recording circuit 9 and a magnetic head 10 are provided on the magnetic track 11 below the photographing screen 23, 24.
Various photographic information including trimming information of the photographic screen 23 and 24 is recorded. This information is reproduced by a printer in the lab and printed according to the specified cropping range.

Note that when a full-size print is designated and photographed, nothing is imprinted at the imprint position 14, and no trimming information is recorded on the magnetic track 11 either. Therefore, if a frame does not have characters indicating the cropping range above the shooting screen of a negative film, it can be understood that the frame was intended to be full size at the time of shooting, and furthermore, the laboratory printer will print full size if no trimming information is recorded. I judge this and print it at full size, exactly as it appeared on the screen at the time of shooting.

FIG. 4 is a flowchart showing a control program executed by the control circuit 17. This program starts execution when trimming size or panoramic size printing is designated by switch SW3 or SW4. The recording operation of trimming information will be explained with reference to the figure.

In step S1, it is determined whether or not the shutter release is performed by the switch SWI, and the same step is repeated until the shutter release is performed.

When the camera is released, the process advances to step S2, where the shutter 16 is driven via the shutter drive circuit 15 to perform exposure.

Next, in step $3, switches SW2 to SW4
It is determined which trimming range has been specified. That is, if the switch SW2 is on, the process proceeds to step S6, if the switch SW3 is on, the process proceeds to step S4, and if the switch SW4 is on, the process proceeds to step S5.

In step S4, the imprinting device 13 is driven via the imprinting circuit 12, and the character r is placed at the imprinting position 14 of the exposure frame.
Imprint PMJ. Further, in step S5, the characters "PANJ" are imprinted at the imprint position 14 of the exposure frame.

In step S6, the motor M is driven via the motor drive circuit 8 to start feeding the film 2 by one frame. In the subsequent step S7, information regarding the photographing of the frame exposed in step S2, that is, the photographing date, photographing conditions, switch S
Photographing information such as trimming information regarding the trimming range during printing designated by W2 to SW4 is recorded on the magnetic track 11 on the film 2 by the magnetic head 10 via the magnetic recording circuit 9.

In step S8, it is determined whether or not one-frame forwarding has been completed, and the same step is repeated until it is completed, and upon completion, the process advances to step S9. In step S9, the motor M is stopped and the execution of the program is ended.

In this way, the shooting information of each frame, including the trimming information, is magnetically recorded on the magnetic track 11 of the film 2, and the trimming range at the time of printing is imprinted with visually understandable characters on the predetermined position of each frame. Just by looking at the negative film, you can easily see what kind of composition that frame was intended for when it was photographed. Therefore, it can be easily determined whether to request a print with the trimming range specified at the time of photography, or to request a print in a range different from the trimming range specified at the time of photography.

In the configuration of the above embodiment, switches SW3゜SW4
constitutes a setting means, the magnetic recording circuit 9 and magnetic head 10 constitute a first recording means, and the imprinting circuit 12 and imprinting device 13 constitute a second recording means.

Detailed explanation of the G0 invention According to the present invention, the cropping range at the time of printing with respect to the full-size photographic screen is recorded in the vicinity of the photographic screen using visually understandable characters or symbols. Just by looking at the developed negative film, you can easily confirm what kind of composition the frame was intended for when it was photographed, making it convenient to handle when requesting prints.
