Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an index print exposure method for producing an index print in which a plurality of images recorded on a photographic film are arranged in a matrix. More specifically, the present invention relates to an index print exposure method capable of recording various information together with the image of each frame.

[0002]

2. Description of the Related Art Images recorded on a photographic film (hereinafter referred to as "negative film") taken by a photographing device such as a camera, index prints arranged in a matrix at predetermined intervals are recorded on the negative film. You can see the images that are present at a glance. In recent years, a photographic system has been proposed in which a negative film that has been subjected to development processing is stored in a cartridge and stored, and in such a photographic system, it is possible to confirm what the negative film in the cartridge is. It is extremely effective to use this index print.

In general, such an index print is an image recorded on one negative film on a CRT.
In accordance with this display, a photosensitive material (color paper) such as photographic paper is exposed to form an index image. When a CRT is used to expose an index image, it is possible to display an image for one negative film at a time and expose the color paper, but an exposure device for exposing the index image onto the color paper is used. It becomes large. For this reason, an index image exposure device using a liquid crystal display has been proposed.

On the other hand, in a liquid crystal display device, since a liquid crystal panel (LCD panel) for displaying images is small, each image becomes small when displaying a large number of images. There is a problem that the roughness of the print becomes noticeable and the finish of the index print is impaired. Therefore, a method in which the index image is divided into a plurality of images, the divided images are sequentially displayed on the LCD panel, and the color paper is exposed can be considered. As a result, the individual images displayed on the LCD panel can be made relatively large, and the roughness of the liquid crystal pixels can be made inconspicuous when finished as an index print.

When an index image is divided and exposed by using such an LCD panel, color paper is quantitatively conveyed so that a boundary portion at the time of divided exposure is located between the exposed images.

By the way, it has been proposed to record information about recorded images in the form of characters, figures, etc. on an index print. It is possible to clearly determine when, where, and for what purpose the image recorded in the index print is captured by the characters and the like recorded in the index print. The characters to be recorded in such an index print should be considered in consideration of the balance with each image of the index print.
The color paper is arranged at one end in the width direction along the longitudinal direction so as not to spoil the appearance of the finished index print.

[0007]

However, if a character or the like is applied to the boundary portion of the divided image, it cannot be recorded in an accurate shape, or the character spacing is deviated, and the quality of the finished index print is impaired. Further, when the display image is corrected in each divided image, the density of the character or the like is changed, and the gradation is different between the divided and exposed characters.

The present invention has been made in view of the above facts, and when recording characters and the like together with the image of each frame in an index print that is created by repeating divided exposure, an index having a good finish quality is provided. An object of the present invention is to provide an exposure method of an index print for producing a print.

[0009]

The invention according to claim 1 is
The index image is divided into image areas in which the images recorded on the photographic film are arranged in a matrix and character areas in which characters and the like are recorded along the transport direction of the photosensitive material are divided. An exposure method for index printing, in which each of the divided images is sequentially displayed on an exposure display device while the photosensitive material is conveyed by a predetermined amount to expose an index image on the photosensitive material to create an index print, which is continuous at regular intervals. When a series of characters that need to be divided are arranged so as to be divided between the characters, the divided characters have a predetermined interval on both sides of the dividing position on the photosensitive material. , The distance between other adjacent characters is displayed on the exposure material display device so as to be the predetermined space on the photosensitive material, and the index is added to the photosensitive material. Characterized by divided exposure images.

According to a second aspect of the present invention, there is provided the index printing exposure method according to the first aspect, wherein the amount of conveyance of the photosensitive material and the divided exposure regions are set so that at least adjacent divided exposure regions are in a non-overlapping state. During the setting, the interval between the arranged characters is set to an integral multiple of the interval between the divided exposure areas adjacent to each other.

According to a third aspect of the present invention, there is provided the index printing exposure method according to the first aspect, wherein the divided exposure areas adjacent to each other are overlapped between the adjacent image frames. When the conveyance amount and the divided exposure area are set, the interval between the arranged characters is set to an integral multiple of the width dimension of the overlapping portion along the photosensitive material conveyance direction.

According to a fourth aspect of the present invention, there is provided the method of exposing the index print according to the third aspect, wherein a linear black pattern having a uniform width along the conveyance direction of the photosensitive material is formed in the character area. When the exposure is performed by dividing into two, the exposure is performed by displaying on the exposure display device so that the figures overlap at the overlapping portion.

The invention according to claim 5 is the index printing exposure method according to any one of claims 1 to 4, wherein the recording area in which a series of characters are recorded is regarded as one image and the density correction is performed separately from the image area. It is characterized by performing.

[0014]

According to the first aspect of the present invention, the characters are arranged at preset intervals so that characters are not applied to the dividing positions during the divided exposure. As a result, it is possible to prevent the characters in the character areas that have been divided and exposed from overlapping each other and deteriorating the finish quality of the index print. Also,
The series of characters recorded on the index print can be evenly spaced, and the quality of the finished index print is not impaired.

In the present embodiment, various characters may be recorded in the character area, and a bar code and various characters formed over the area in which a plurality of characters can be recorded. It may be a figure. Even in these cases, the character interval may be set by treating it as one character or a word in which characters are connected.

According to the second aspect of the present invention, when a gap is formed between the divided image areas adjacent to each other on the photosensitive material, the character spacing to be recorded in the character area is an integral multiple of this spacing ( To be more precise, it is set to a natural number multiple).

According to the third aspect of the invention, the character spacing is set to an integral multiple (natural multiple) with respect to the width dimension of the overlapping portion of the divided image areas.

By setting the character spacing in this way, it is possible to obtain an index print in which characters are recorded at equal intervals and which has a good finish quality. Further, it becomes extremely easy to change the character spacing according to the number of characters.

According to the invention of claim 4, when the line segment recorded in the character area extends over a plurality of divided images,
It is formed in black. For example, when three colors of red (R), green (G), and blue (B) are overlaid to form a color image on a photosensitive material, even if the images are exposed by overlapping with black, the exposure time It is possible to prevent the difference between the two from being substantially noticeable.

According to the fifth aspect of the invention, the character area is treated as one image similar to the image of each frame in the image area, image processing is performed separately from the other images, and the photosensitive material is exposed.
As a result, it is possible to prevent the gradation change of the character in the character area from appearing when the divided exposure is performed, and it is possible to obtain the index print in which the character is recorded with a constant gradation. Also, since it is possible to prevent changes in gradation and the like,
It can be exposed to any color.

The negative film 12 from which each image has been read is then mounted on the film exposure section 16 of the photographic printer 10 and the exposure of the color paper 14 according to the image of each frame is started.

On the other hand, in the index exposure unit 18, the storage device 7 is provided prior to the operation of exposing the image of the negative film 12 mounted on the film exposure unit 16 onto the color paper 14.
Image data is read from 0, the number of exposures N is set, and the index image displayed on the LCD panel 52 and exposed on the color paper 14 is processed. An outline of the exposure operation in the index exposure unit 18 will be described with reference to the flowcharts shown in FIGS. 6 and 7.

The flowchart shown in FIG. 6 is executed when the index exposure unit 18 instructs the exposure process of the index image on the color paper 14, and the negative film 12 stored in the storage device 70 in the first step 100. Image data is read, images of each frame are arranged in a matrix in an area corresponding to the image area 82 and displayed on the CRT display 74 (step 1).
02). Next, the number of frames is judged from the read image data, and the number of divided exposures N for exposing each 10 frames is set (step 104).

By setting the number N of divided exposures, an index on the color paper 14 is obtained from the width dimension D ₁ of the divided image area, the carry amount D ₂ of the color paper 14 at the time of divided exposure, the total number of exposed frames, and the like. An area for recording an image can be obtained, and the film exposure unit 16 starts the image exposure of each frame after idling the area.

On the other hand, in the next step 106, it is confirmed whether or not the character to be inserted in the character area 84 is selected or input, and if an affirmative judgment is made, that is, if the data of the character to be recorded in the character area 84 is input, In step 108, the input data is read.
Next, the number of characters or the like is determined from the read data, the character spacing d ₁ is set from the preset and stored data, and one character straddles the boundary portion when performing divided exposure. Set the layout so that nothing happens. At this time, the character layout can be easily set by storing in advance the positions of the characters adjacent to the boundary where the divided exposure is performed with respect to the character spacing d ₁ . The characters to be recorded in the character area 84 are recorded in advance on the magnetic recording layer 13 of the negative film 12,
You may make it input automatically.

Next, the characters input in the set layout are displayed in the area corresponding to the character area 84 of the CRT display 74 (step 112). Here, the position of the character is corrected if necessary while confirming the display on the CRT display 64 (step 116). Next, when the layout of characters to be recorded in the character area 84 is determined (confirmed in step 116), the process proceeds to step 118 and the LCD
Image processing such as correction for performing exposure by displaying on the panel 52 is performed.

In the image processing performed in step 118,
With respect to the image divided and displayed on the LCD panel 52, for example, the gradation for displaying for each color of R, G, B is corrected for each image of each frame, and when the color paper 14 is exposed, the density and the like are substantially constant. So that

In this image processing, the character area 84
All the characters to be recorded in 1 are regarded as one image, and the gradation of each color is corrected separately from the image of each frame of the negative film 12 so that the density of the character becomes constant in any divided exposure. As a result, even if the character recorded next in the character area 84 is divided and exposed to the color paper 14,
It is possible to prevent the difference in gradation from occurring, and it is possible to obtain the index print 80 with good quality. That is, the character area 84 is regarded as one image, and is subjected to image processing and then divided.

On the other hand, the flowchart of FIG. 6 shows an example of the exposure processing in accordance with the conveyance of the color paper 14 in the index exposure section 18. This flowchart is executed when the color paper 14 is fed from the film exposure unit 16, and the conveyance of the color paper 14 fed in the first step 130 at a constant speed is started. At the same time, in the next step 132, it is determined whether or not the index image is exposed on the color paper 14.

Here, when the exposure of the index image on the color paper 14 is instructed and the image processing section 68 is performing the image processing (affirmative determination at step 132),
In step 134, the division exposure counter T is set (T = 1) and the division exposure number N is read.

Next, in the film exposing section 16, the color paper 14 which has been fed for recording an index image is fed.
When the unexposed region of is exposed to the index exposure unit 18, the front end of the unexposed portion is positioned at the exposure position (step 136) and the LCD panel 52 is prepared for exposure such as displaying the first divided image. To do.

Thereafter, in step 140, the color paper 14 is exposed according to the image displayed on the LCD panel 52. In this exposure process, the R, G, and B color images of each divided image are displayed on the LCD panel 52, and the color filter 54 is driven to irradiate the LCD panel 52 with light of a color corresponding to the display image. , And color paper 14 is overlaid and exposed.

In the next step 142, it is confirmed whether or not the overexposure for the three colors of the divided image is completed, and when an affirmative decision is made, the routine proceeds to step 144, where it is confirmed whether or not the divided exposure for a predetermined number of times is completed. When the divided exposure has not reached the predetermined number (divided exposure number N), 1 is added (incremented) to the divided exposure counter T to perform exposure of the next divided image (step 146), and the pulse motor 66 is used. Is driven to convey the color paper 14 by the carry amount D _2, and the area for exposing the next divided image is positioned at the exposure position, and then the T-th divided exposure is performed.

As a result, for example, one character is not divided in the character area 84 by the Mth exposure and the M + 1th exposure, and a series of characters is uniformly spaced d _1.
(See FIG. 4B).

When a predetermined number of divided exposures are completed (affirmative determination in step 144), the process moves to the first step 130 and the color paper 14 is conveyed at a constant speed and sent out from the index exposure section 18. This flowchart is for the color paper 14 from the index exposure unit 18.
When the exposure process is continued in the film exposure unit 16, the necessity of exposure of the index image is always confirmed in step 132, and the exposure process of the index image can always be started.

In the index print 80 having the index image formed and finished in this way, characters are not hung on the boundary portion of the image which is divided and exposed, and even when the divided exposure is performed, the character area is formed. Characters recorded in 84 are not irregularly spaced and are not irregular, and characters are recorded at uniform intervals, resulting in good quality.

Second Embodiment Next, a second embodiment of the present invention will be described. The basic configuration of the second embodiment is the same as that of the first embodiment, and the same parts are designated by the same reference numerals and the description thereof will be omitted.

The CD panel 52 blocks light to the overlapping portion 90.

The width dimension d ₄ of the overlapping portion 90 along the transport direction of the color paper 14 is D ₁ -D ₂ = d ₄ , (where 0 <d ₄ <d ₁ ) and recorded in the character area 84. The character spacing d ₁ is set to be an integral multiple (preferably an integral multiple of 2 or more) of the width dimension d ₄ of the overlapping portion 90.

D ₁ = nd ₄ (where n = 1, 2, 3, ...) By setting the character spacing d ₁ to be recorded in the character area 84 in this way by setting the width dimension d ₄ of the overlapping portion 90, The character area 8 of the index print 80 is the same as that described in the first embodiment.
4, characters can be recorded at uniform intervals, and an index print 80 with good finish quality can be obtained.

In the first and second embodiments, the character spacing d ₃ recorded in the character area 84 of the index print 80 formed by the divided exposure is defined as the gap d ₂ between the divided exposure areas or the width dimension of the overlapping portion 90. Although it is set as an integral multiple of d ₄ , at least d ₂ , d ₃ ≧ d, or d ₂ , d ₃ ≧ d ₄ (however, d ₂ <d ₃ ) and the gap d ₂ of the divided exposure area or the overlapping portion. 90
It may be set so that characters and the like do not straddle each other, and the arrangement of the characters may be adjusted by the character interval and the interval between words formed of the example characters. In addition, the graphic may be arranged as one character or a series of words.

[Third Embodiment] Next, a third embodiment of the present invention will be described with reference to FIG. In addition, this Example 3
Then, the basic configuration is the same as that of the second embodiment, and the same components are given the same reference numerals and the description thereof is omitted.

When the divided exposure is performed, the overlapped portions 90 are provided in the divided image areas adjacent to each other on the color paper 14, or at least no gap is formed so that a linear figure with a constant width is recorded in black. be able to. At this time, the characters to be recorded in the title frame 94 are arranged at the interval d ₁ and do not overlap with each other when the divided exposure is performed, so that the characters can be recorded in an arbitrary color different from that of the title frame 94.

Although the present invention is applied to the index exposure unit 18 provided integrally with the photographic printer 10 in this embodiment, the application of the present invention is not limited to this. The present invention may be applied to an index exposure unit provided in a printer processor that performs development processing, or may be applied to a so-called index printer that exposes an index image by itself.

[0070]

As described above, according to the present invention, when the index image is divided and exposed on the photosensitive material, the characters to be recorded in the character area are not applied to the boundary portion when the divided exposure is performed. The desired character can be accurately recorded on the print. Also, by setting the character spacing according to the gap of the exposure area or the width dimension of the overlapping portion at the time of divided exposure, the characters can be arranged at regular intervals, and the finish quality of the index print can be improved. It has an excellent effect.
