Description

PAR information recoding device and method for advanced photo system camera}

The present invention relates to a device for recording aspect ratio (PAR) information of an Advanced Photo System (APS) camera and a method thereof. More specifically, the present invention relates to photographing information on a film using a single light emitting diode. An information recording apparatus of an advanced photo system camera for recording and a method thereof. .

As information is diversified according to industrial development, user needs are also diversified. Accordingly, cameras are becoming more versatile to satisfy various needs of users.

In response to this, an advanced photo system camera for recording photographing data on a film by magnetic information has been developed.

The film used for the Advanced Photo System camera is different from the film used for general cameras, and the number of films, film sensitivity, and type are recorded on the data disk mounted on the top of the film. It is possible to record in any area of the.

In addition, the Advanced Photo System camera can be used in various screen sizes, unlike 135 films (films used in conventional general automatic cameras). In other words, different ratios of the width and width of the prints recorded in each frame can be obtained to obtain a desired picture.

As shown in the accompanying FIG. 5, the picture size of the advanced photo system camera is determined according to the high vision size, the panorama size, and the like, depending on the aspect ratio of the prints recorded on the frame. It is divided into classic sizes. The high-vision size (H) has a film size of 27.4 × 15.6 mm, the panoramic size (P) has a film size of 127.4 × 9.6 mm, and the crack size (C) is a size of 22.3 mm × 15.6 mm Has

Hereinafter, with reference to the accompanying drawings, a description will be given of an operation of recording on a film the information of a screen size, i.e., high-vision, panorama, and classic, selected by an information recording apparatus of a conventional advanced photo system.

4 shows an information recording apparatus of a conventional advanced photo system camera. As shown in FIG. 4, the film used in the advanced photo system has two perforations formed per frame, unlike the conventional 35 film. Detect perforation At the bottom of the frame, an information recording unit 60 composed of two light emitting diodes is positioned at a corresponding position so as to record information corresponding to the selected screen size, that is, print aspect ratio (PAR) information.

In this conventional information recording apparatus, when the film is mounted on the camera, the film transfer is performed according to the information recorded on the data disc of the film as described above, and the film transfer is performed at the position where the first perforation of the unexposed frame is detected. Stop.

In general, the film for an advanced photo system camera is divided into four types, that is, unexposed, partial, processed, and exposed, unlike the conventional 135 film type. The film state information is classified according to the position of the data disk formed at the upper end of the film cartridge for the advanced photo system camera, that is, the rotation angle.

Therefore, when the film for APS is mounted, the control device of the camera detects the rotation angle of the data disk, and if the currently mounted film is an unexpanded film, performs film winding to the corresponding initial position, and mounts it. If the film is a partial film, the film transfer is performed to the next frame of the photographed frame, and in the case of the exposed film, the film is controlled to display that the currently mounted film is used film.

When the film transfer is stopped at the position where the first perforation of the frame to be photographed is detected according to the state of the film, as shown in FIG. 4 attached by the inertial force of the film transfer motor, the first frame of the frame to be scanned The film is stopped at the overrun position slightly past the position corresponding to the first perforation.

In this state, when the exposure operation is performed by the operation of the shutter button (not shown), the light emitting diode of the information recording unit 60 is operated to record the PAR information selected by the photographer at the bottom of the frame. In this case, when the screen size selected by the photographer is a high vision size, the light emitting diode is not driven. In the case of the panorama size, only one light emitting diode is driven to record 1 bit of information. All LEDs are driven to record two bits of information.

However, in the conventional information recording apparatus operating as described above, the PAR information is recorded by using two light emitting diodes, resulting in an increase in cost and inferior space installation efficiency.

Unlike the prior art, a technique for recording PAR information using light incident through a photographing lens without using a separate light emitting diode is disclosed in Korean Patent Application No. 96-78002 (December 30, 1996). 'Information recording device of an advanced photo system camera' and US patent application 5,740,479.

However, the prior art disclosed above requires a plate that selectively blocks light incident through the photographing lens and a driving mechanism for driving the same according to the screen size selection switch, which results in complicated structure, low space efficiency, and increased number of parts. As a result, product cost increases.

Therefore, it is an object of this invention to record PAR information on a film using one light emitting diode in an advanced photo system camera.

Further, another object of the present invention is to provide an information recording apparatus of an advanced photo system, which is excellent in space efficiency, simple in construction, and reduced in product cost.

In order to achieve this object of the present invention, in the present invention, PAR information of classic, panoramic, and high-vision screen sizes is recorded on a film by using one light emitting diode.

When the high-vision screen size is selected by the screen size selection means, the control means transfers the frame without driving the light emitting diode which is the information recording means. When the panoramic screen size is selected, one light emitting diode, which is an information recording means, emits light once to record one bit of information, and then drives the film conveying means to transfer the frame. When the classic screen size is selected, one light emitting diode is emitted once to record 1 bit of PAR information, and then the film is transported. When the first perforation of the frame is detected by the film transport, the film transport is stopped. The LED emits light once to record 1 bit of PAR information, and then transfers the film. When the second perforation of the corresponding frame is detected according to the film transfer, the film transfer is terminated.

In this way, PAR information according to the screen size selected by the photographer is recorded on the film.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a structure of an information recording apparatus of an advanced photo system camera according to an embodiment of the present invention, FIG. 2 shows a film structure according to the present invention, and FIG. 3 shows information according to an embodiment of the present invention. A flowchart of the recording apparatus method is shown.

As shown in FIG. 1 and FIG. 2, in the information recording apparatus of the advanced photo system camera according to the present invention, the perforation detector is provided at a corresponding position capable of detecting perforations P1 to P4 formed on the upper end of the film. 10 is located, and the operation control unit 40 is located at the output terminal of the perforation sensor 10. The information recording unit 60 is located at the output terminal of the operation control unit 40, and the information recording unit 60 is located corresponding to the position where the PAR information at the bottom of the film is recorded.

A release switch S1 that is operated in conjunction with a shutter button for selecting shooting and a screen size selection switch S2 for selecting a screen size of high vision, panorama, classic, etc. are connected to an input terminal of the operation controller 40. have. In addition, the metering unit 20 for measuring the brightness of the subject, the metering unit 30 for measuring the distance of the subject is connected to the input terminal of the operation control unit 40, the shutter driving unit for performing exposure by operating the shutter ( 70 is connected to the output terminal of the operation control unit 40.

The information recording unit 60 according to this invention consists of one light emitting diode. The film perforation sensing unit 10 includes a light emitting device that emits a predetermined amount of light and a light receiving device that receives light and outputs an electrical signal.

The operation of the information recording apparatus of the advanced photo system camera according to the embodiment of the present invention having such a structure is as follows.

When the film is mounted in the advanced photo system camera, the operation control unit 40 reads whether the current film is in an unexpanded or partial or processed or exposed state from a data disk mounted on the top of the film. When the film is in an unexpanded state, the first frame is positioned at the photographing position, and in the case of the partial state, the film is transferred to the next frame after the last exposed frame.

The operation control unit 40 drives the film transfer unit 50 according to the mounting of the film, so that the unexposed frame, that is, the non-photographed frame, is positioned at the photographing position. As the film is transported, the light emitting device of the perforation sensor 10 emits a predetermined amount of light, and the emitted light is irradiated to a portion where the perforation is formed.

When the light from the perforation detector 10 is irradiated to a portion where perforation is not formed, the light is reflected by the film and received by the light receiving element of the perforation detector 10 again. In this case, in the embodiment of the present invention, the light receiving element is configured to output a low level electric signal, but is not limited thereto.

On the contrary, when the light from the perforation detector 10 is irradiated to the portion where the perforation is formed, the light is not incident to the perforation detector 10 again as the light passes through the perforation. Therefore, in this case, the light receiving element outputs a high level electrical signal.

In this way, the operation control unit 40 determines the film transfer state according to the electrical signal output from the perforation detection unit 10. When the mounted film is in an unexpanded state, the operation controller stops driving the film transfer unit 50 when the first perforation of the third frame is sensed and then the second perforation is sensed. In addition, even when the mounted film is in a partial state, the driving of the film transfer unit 50 is stopped when the second perforation of the last exposed frame is detected.

At this time, due to the inertia of the motor (not shown) of the film transfer unit 50 is not located directly in the second perforation of the previous frame of the frame to be taken and stops by moving a certain distance further. Accordingly, as shown in FIG. 4, the perforation detector 10 is positioned beyond a predetermined distance dΔ in the second perforation of the previous frame # 1 of the frame # 2 to be photographed. .

As described above, after the frame to be photographed is transferred to the photographing position, the photographer operates the screen size selection switch S2 to select a desired screen size, and the operation control unit 40 displays PAR information corresponding to the selected screen size. Save to internal memory Next, when the release switch S1 is operated by the operation of the shutter button (not shown), the operation control unit 40 releases the shutter according to the subject brightness and distance measured by the light metering unit 20 and the ranger 30. The driving amount is set, and the shutter driving unit 70 is operated in accordance with the set shutter driving amount. Thus, a shutter (not shown) is opened to take a picture.

The operation controller 40 simultaneously records the PAR information on the screen selected by the photographer according to the flowchart shown in FIG. 3 attached to the film. When shooting starts in response to the shutter opening, the operation control unit 40 reads the PAR information selected by the photographer from the internal memory (not shown) (S110 to S120). When the selected screen size is the panorama size, the operation recording unit 60 is read. Drive once to record the PAR information on the film. That is, under the control of the operation controller 40, the light emitting diode of the information recording unit 60 emits light once, and 1-bit PAR information corresponding to the panorama is recorded at the bottom of the frame (S130).

When recording and capturing the PAR information is completed, the operation controller 40 drives the film transfer unit 50 to transfer the photographed frame. When the signal according to the detection of the second perforation (P3) is output after outputting a signal according to the detection of the first perforation (P2) of the frame photographed from the perforation detector (10) according to the film transfer, the operation control unit ( 40 stops the driving of the film transfer unit 50 to end the film transfer (S140 to S150).

When the screen size selected by the photographer is a high vision size, the operation control unit 40 drives the film transfer unit 50 according to the end of shooting without driving the information recording unit 60 so that the second perforation of the photographed frame is obtained. The film transfer is terminated when it is detected (S140 to S150).

When the screen size selected by the photographer is the classic size, the operation control unit 40 first drives the information recording unit 60 once and then drives the film transfer unit 50 to start the film transfer. That is, in the same way as the panorama size PAR information recording, the light emitting diode of the information recording unit 60 emits light once, writes one bit of PAR information on the film, and then starts film transfer (S160 to S170).

When the signal according to the detection of the first perforation (P2) is output from the perforation detection unit 10 in accordance with the film transfer, the operation control unit 40 stops the driving of the film transfer unit 50 to stop the film transfer, Again, the LED of the information recording unit 60 is driven once to record 1-bit PAR information. Therefore, when the classic size is selected, a total of 2 bits of PAR information is recorded at the bottom of the frame (S180 to S200).

After recording the PAR information corresponding to the classic size as described above, the operation control unit 40 drives the film transfer unit 50 again to recover the film transfer, and the second perforation from the perforation detection unit 10 in accordance with the film transfer. (P3) When the signal according to the detection is output, the film transfer is terminated (S210 to S230).

As described above, 0 bit PAR information is recorded at the bottom of the frame when the screen size selected by the photographer is high vision, and 1 bit PAR information is recorded at the bottom of the frame when the selected screen size is panorama. If the selected screen size is classic, two bits of PAR information are recorded at the bottom of the frame.

Therefore, one piece of light emitting diode can distinguish each piece of PAR information and record it on a film.

At the time of film development, the developer reads the PAR information recorded in this way and develops the film according to the selected screen size, so that the photographer can obtain a picture of a desired size.

As described above, according to the embodiment of the present invention, in the advanced photo system camera, PAR information can be easily recorded using one light emitting diode.

Therefore, the number of parts is reduced, the cost is reduced, and the configuration is simplified, thereby providing the effect of increasing the space efficiency.

This invention is susceptible to various modifications without departing from the claims set out below.
